Spray towers, also known as wet scrubbers or spray scrubbers, are air pollution control devices used to remove harmful gases and particulates from industrial emissions.These sophisticated systems effectively cleanse exhaust gases, ensuring environmental compliance and protecting public health by reducing air pollution. In this article, we delve into the intricacies of spray towers, exploring their workings, types, benefits, and applications across various industries.

Electrostatic precipitators, commonly abbreviated as ESPs, are advanced air pollution control devices that efficiently remove particulate matter, such as dust and smoke particles, from industrial exhaust gases.

The biological scrubber has the following features:

Efficient purification capacity: The bioscrubber uses the biodegradation capacity of microorganisms to efficiently remove organic pollutants in the exhaust gas, such as volatile organic compounds (VOCs), ammonia, etc. Microorganisms grow and multiply inside the tower, forming biofilms, or bio-particles, that convert organic pollutants into harmless substances.

Wide applicability: The biological scrubber is suitable for the treatment of various organic waste gases, including industrial waste gas, chemical waste gas, printed waste gas, etc. It can handle high and low concentrations of exhaust gases and adapt to different temperature and humidity conditions.

Low energy consumption and low operating costs: In the process of treating waste gas, the biological scrubber does not require external energy supply, and the microbial degradation process is natural and environmentally friendly. In addition, it does not require the use of expensive media substances and has low operating costs.

Stability and reliability: The bioscrubber has good stability and operational flexibility. The microorganism is attached to the filler or supporting material, which can adapt to different load changes and operating conditions, and maintain a high processing efficiency.

Advantages of electrostatic precipitator

2. Energy saving: In regenerative thermal oxidizer system, the heat from the exhaust gas is recovered through the heat exchanger, which improves the energy utilization efficiency and reduces the production cost.

Desulfurizing Tower process Introduction

The flue gas enters the cylinder of the spray desulfurization tower, and forms a contact interface with the absorber slurry spray cloud in the internal rising stage of the spray desulfurization tower (the flow rate is 1.5-2m/s). The flue gas and the liquid fog particles are fully in contact with the countercurrent, and the dust particles wet by absorbing S02 and trapping dust particles flow down into the bottom of the desulfurization tower in the process of fog particles landing, and are discharged into the sedimentation tank from the overflow hole. The purified gas rising in the cylinder is defogged and dehydrated by the gas-water separator to complete the whole dust removal and desulfurization procedure, and then is led out through the upper cone part of the cylinder. The waste liquid is discharged into the sedimentation tank through the overflow hole at the bottom of the cylinder, (the overflow hole has water seal design to prevent air leakage, and is equipped with a cleaning hole to facilitate the cleaning at the bottom of the cylinder) after precipitation (ash removal) and alkali (regeneration) recycling. At the same time, in order to facilitate the maintenance of the desulfurization system and deal with emergencies, a bypass flue can be built if conditions permit.

Municipal sewage (municipal wastewater) A general term for sewage discharged into the urban sewage system. In the combined drainage system, production wastewater and rainwater interception are also included.

First, from the perspective of water quality and treatment technology, urban domestic sewage, especially the domestic sewage without flushing and drainage, has good water quality and high organic matter content. Many uses of water in cities, such as cooling, flushing, building, irrigation, etc., do not require high water quality. Sewage utilization technology has been developed and mature, and water treatment technology can fully meet its technical support.

Second, from the perspective of water quantity, urban sewage volume and water consumption are almost equivalent, and rainwater has the characteristics of seasonality and randomness, which can be used as urban reclaimed water.

Third, from the perspective of engineering construction, the use of urban sewage and rainwater need to use equipment far smaller than the use of tap water required by the amount of engineering.

Four, from the economic point of view, not only save pure water resources, but also reduce the cost of sewage, reduce the cost, there are significant economic benefits.

Domestic sewage treatment is an important role in water resource management in urban and rural areas, with the following applications and implications:

1. Protection of water resources: through the treatment of domestic sewage, reduce the pollution of water resources and protect the sustainable use of water resources.

2. Prevention of disease transmission: The treatment of domestic sewage can effectively kill pathogenic microorganisms and reduce the risk of disease transmission.

3. Improve environmental quality: domestic sewage treatment can reduce water and soil pollution, improve environmental quality,

4. Promote sustainable development: Domestic sewage treatment can improve the utilization efficiency of water resources and promote sustainable development of urban and rural areas.

Through domestic sewage treatment, environmental pollution can be reduced, sustainable use of water resources can be protected, and people's living environment can be improved.

The pollution caused by industrial wastewater mainly includes: organic aerobic material pollution, chemical toxicant pollution, inorganic solid suspended matter pollution, heavy metal pollution, acid pollution, alkali pollution, plant nutrient pollution, thermal pollution, pathogen pollution, etc. Many pollutants have color, odor or foam, so industrial wastewater often presents an aversive appearance, resulting in large areas of water pollution, directly threatening people's life and health, so it is particularly important to control industrial wastewater.

A characteristic of industrial wastewater is that the water quality and quantity vary greatly depending on the production process and mode of production. Such as electricity, mining and other sectors of the wastewater mainly contains inorganic pollutants, and paper and food and other industrial sectors of the wastewater, organic matter content is very high, BOD5(five-day biochemical oxygen demand) often more than 2000 mg/L, some up to 30000 mg/L. Even in the same production process, the water quality in the production process will change greatly, such as oxygen top blowing converter steelmaking, different smelting stages of the same furnace steel, the pH value of wastewater can be between 4 ~ 13, suspended matter can be between 250 ~ 25000 mg/L.

Another characteristic of industrial wastewater is: in addition to indirect cooling water, it contains a variety of materials related to raw materials, and the existence form in wastewater is often different, such as fluorine in glass industry wastewater and electroplating wastewater is generally hydrogen fluoride (HF) or fluoride ion (F-) form, and in phosphate fertilizer plant wastewater is in the form of silicon tetrafluoride (SiF4); Nickel can be in ionic or complex state in wastewater. These characteristics increase the difficulty of wastewater purification.

The amount of industrial wastewater depends on the use of water. Metallurgy, paper making, petrochemical, electric power and other industries use large water, the amount of waste water is also large, such as some steel mills smelting 1 ton of steel waste water 200 ~ 250 tons. However, the actual amount of wastewater discharged from each factory is also related to the recycling rate of water.

Belt dryer is a common drying equipment. Its working principle is to send the high humidity material into the dryer through the conveyor belt. After heating, the water gradually evaporates, and then the moisture is discharged through the exhaust fan, so as to achieve the purpose of drying.

Specifically, the belt dryer is mainly composed of conveyor belt, heater, fan and so on. The material is transmitted to the heater through the conveyor belt, and the water on the surface of the material begins to evaporate after being heated by the hot air in the heater. As the material moves, the water gradually evaporates until the material is completely dry. The exhaust fan pulls the air with water vapor out of the dryer, so as to ensure that the relative humidity inside the dryer is lower than the ambient humidity and ensure the drying effect of the material. Finally, the material is exported from the outlet of the dryer and the whole drying process is completed.

Belt dryer has the advantages of fast drying speed, high efficiency and good drying quality, which is widely used in food, chemical, pharmaceutical and other industries. At the same time, when using the belt dryer, it is necessary to pay attention to the input amount of materials, temperature, humidity and other factors to ensure the stability of the drying process and the drying effect of materials.

The expansion coupling sleeve is used to connect the main shaft of the thin film drying machine, which reduces the friction loss between the main shaft and the bearing. The structure is simple and easy to use.

4) In the sludge mixing and firing power generation project, the control of dry sludge form and moisture content is very critical, which will affect the operation of the subsequent incineration system of the drying system. On the one hand, the horizontal thin film drying process can generate granular products with uniform particle size and no dust, and on the other hand, it can quickly realize the adjustment of moisture content by changing the steam pressure and the speed of the two-stage linear drying machine. The good control of the shape and moisture content of the dry sludge can ensure the stable operation of the whole system.

The equipment has the advantages of simple operation, large processing capacity and good separation effect.

Filter press sludge dewatering machine is a widely used equipment in industry, which can effectively separate solids from liquids. Filter press functionality is derived from high-pressure operation, which compacts the solid filter cake and minimizes moisture content. This core technology solves the solid-liquid separation problem in many industries and is an important part of industrial production.

The operation of the sludge dewatering filter press consists of several steps. First, the slurry (a mixture of solid and liquid) is delivered to the filter press under high pressure. Then, the corresponding filter media (such as filter cloth) will trap the solids in the slurry and allow the liquid to pass through. The separated liquid, also called filtrate, is discharged through a system of pipes. In this process, the high pressure not only effectively separates the solid, but also compreses the moisture of the filter cake and improves the drying degree of the filter cake.
