Problems solved by technology

[0007] The co-processing of combustible waste in cement kilns will bring a large number of harmful components (such as potassium, sodium, chlorine, sulfur, etc.) that affect the quality of cement. At present, the ability of cement kilns to co-process combustible waste without affecting the quality of cement is limited. ; Therefore, in order to improve the ability of cement kilns to co-process combustible wastes, some technologies adopt the method of bypass ventilation, but bypass ventilation will cause additional energy loss, so the ventilation volume is generally controlled at the kiln tail outlet of the total flue gas Amount of 5%-10%, still slightly insufficient

Abstract

The invention relates to a cement kiln cooperative processing combustible waste and by-pass exhaust power generation complementary system. The cement kiln cooperative processing combustible waste and by-pass exhaust power generation complementary system aims to have higher combustible waste processing capacity and can guarantee the production quality of cement. According to the technical scheme, the cement kiln cooperative processing combustible waste and by-pass exhaust power generation complementary system comprises a power generation device, a kiln tail preheater, a kiln head waste heat boiler and a kiln tail waste heat boiler, wherein the kiln head waste heat boiler and the kiln tail waste heat boiler are connected with the power generation device through a steam circulation loop; an air inlet of the kiln head waste heat boiler is connected with an exhaust gas outlet of a clinker cooler; an exhaust gas outlet of the kiln tail preheater is connected with an air inlet of the kiln tail waste heat boiler; a discharge outlet of the kiln tail preheater is connected with a feed inlet of a feed-end chamber in a rotary kiln. The cement kiln cooperative processing combustible waste and by-pass exhaust power generation complementary system further comprises a collection device, an incinerator, a raw material vertical mill and a by-pass exhaust device, and an exhaust gas outlet of the incinerator is connected into a decomposing furnace of the kiln tail preheater.

Description

technical field [0001] The invention relates to a combustible waste system, in particular to a cement kiln cooperative processing combustible waste system. Background technique [0002] Combustible waste refers to the solid and semi-solid waste produced by human beings in production, consumption, life and other activities, which has a certain calorific value and can be burned under certain conditions (the definition abroad is more extensive, and waste produced by animal activities also belongs to this category), in layman's terms, it is "garbage" with calorific value. Combustible waste mainly includes municipal solid waste, crop straw, sludge, discarded plastic or rubber products, damaged wooden furniture, animal carcasses, spoiled food, human and animal manure, etc. [0003] The European Union has made several changes in the treatment of combustible waste such as municipal solid waste and sludge: at the beginning, it was mainly landfill and incineration, and the ash after ...
