Benefits of technology

Inventions described earlier have several benefits such as reducing costs associated with handling lignocleous slurry (LSC) and disposable plaster boards (SPB). By combining these processes together, energy consumption reduces emissions while producing useful products like ceramics. Additionally, the apparatuses mentioned allow for efficient collection and recycling of resources without generating any harmful substances. Overall, these improvements improve environmental impactiveness and lower operational expenses compared to traditional methods.

Problems solved by technology

Technologies described in the technical problem addressed in this patents include improving the efficiency and effectiveness of treatments involving animal sources like cowhide residues (CR), poultry shell scrains (PS) and fish scales, while reducing their negative effects on both human health and natural environments. Current solutions involve either disposing them directly back onto animals or burning them at harvest sites, resulting in potential contamination issues. Additionally, current techniques require significant amounts of energy input during decomposition processes due to the presence of organics containing nitrogen compounds called ammoniacal metals ("AMS"), making it challenges to dispose of AML".

Abstract

The invention relates to a device for disposing leather sludge and waste by using a cement kiln and a process method of the device, and belongs to the technical field of leather waste treatment. The device is characterized in that a discharging hole of a storage tank (29) communicates with a feeding hole of a decomposing furnace (23) through a feeding device, a discharging hole of the decomposingfurnace (23) communicates with feeding holes of preheaters (22), and discharging holes of the preheaters (22) communicates with a feeding hole of the cement kiln (25); and an air outlet of the cementkiln (25) and an air outlet of the decomposing furnace (23) communicates with air inlets of the preheaters (22), air outlets of the preheaters (22) is connected with a dust remover, and the storage tank (29) is also connected with a negative pressure pumping device. The device for disposing the leather sludge and waste by using the cement kiln is low in treatment cost, and no secondary pollution exists in the treatment process; and according to the process method, residue ash obtained by combustion of the leather sludge and waste and kiln feeding cement raw material are preheated and then enter the cement kiln to be calcined, so that the influence on the quality of produced cement can be avoided.
