3. Binciken amfani da makamashi na tattalin arziki yayin ƙaddamar da na'urar bushewa na bakin ciki

Bayan kusan rabin wata na aikin ba da izini guda ɗaya da aikin laka na tsarin bushewar fim na bakin ciki, sakamakon shine kamar haka.

Ƙaƙwalwar ƙirar ƙirar ƙira na na'urar bushewa na bakin ciki guda ɗaya a cikin wannan aikin shine 60 t / d. A halin yanzu, matsakaicin matsakaicin jiyya na sludge yayin lokacin ƙaddamarwa shine 50 t / d ( abun ciki mai ɗanɗano shine 79%), wanda ya kai 83% na sikelin jiyya na sludge rigar tushe da 87.5% na ƙirar ƙirar bushewar tushen jiyya.

Matsakaicin danshi na sludge mai bushewa wanda na'urar bushewar fim ɗin bakin ciki ke samarwa shine 36%, kuma abun ciki mai ɗanɗanon busasshen busassun busassun busassun busassun busassun na'urar bushewa yana fitar da shi shine 36%, wanda yake daidai da ƙimar ƙimar ƙirar ƙirar (35%).

Aunawa ta waje cikakken tururi mita a cikin sludge bushewa bitar, da cikakken tururi amfani ne 25 t/d, da theoretical jimlar yawan zafin rana na latent zafi na tururi vaporization ne 25 t × 1 000 × 2 014.8 kJ/kg÷4.184 kJ = 1.209 × 1.209 × 8. Matsakaicin jimlar ruwan ƙafe na yau da kullun na tsarin bushewa shine (50 t ×0.79) - [50 t × (1-0.79)] ÷ (1-0.36) × 1 000 = 23 875 kg / d, Sa'an nan naúrar zafin amfani da tsarin bushewa na sludge shine 1.203 871 9 × 8porated / 5k ruwa; Saboda sludge bushewa tsarin ne batun da canji na rigar sludge danshi abun ciki, da ingancin waje tururi, da kuma halaye na Semi-bushe sludge samfurin sufuri kayan aiki ga granularity bukatun da sauran dalilai, shi wajibi ne don inganta darajar daban-daban masu canji a nan gaba dogon lokacin da gwaji aiki, don haka kamar yadda ya taƙaita mafi kyau aiki yanayi da kuma tattalin arziki makamashi amfani index na tsarin.
