Automatic time-sharing reversing system and method for double-hearth lime kilns

Abstract

The invention provides an automatic time-sharing reversing system and method for double-hearth lime kilns. The system comprises an automatic coordination switchboard, an upper computer and lower computers, which are in communication connection. The lower computers associate and control the double-hearth lime kilns in a one-to-one correspondence mode so as to collect fuel gas reversing signals of the multiple double-hearth lime kilns and feed the fuel gas reversing signals back to the automatic coordination switchboard through the upper computer. The automatic coordination switchboard ranks the sequence of the gas reversing events of the multiple double-chamber lime kilns according to the internal program logic measurement and calculation of the automatic coordination switchboard, and sequentially sends a reversing allowing instruction to the lower computers through the upper computer, and the lower computers are switched in one by one to control the gas reversing of the double-chamber lime kilns. And after reversing is completed, the lower computers send reversing completion signals to the automatic coordination switchboard through the lower computers, so that automatic worry-free real-time control is realized, manual nursing is not needed, the labor intensity of operators is reduced, the vigor and manpower of the operators are saved, the production efficiency is improved, and the accident rate and the energy consumption are reduced.

Description

technical field [0001] The application belongs to the technical field of lime production, and more specifically relates to an automatic time-sharing reversing system for a double-bore lime kiln and an automatic time-sharing reversing method for a double-chamber lime kiln. Background technique [0002] For factories that use double-chamber lime kilns to produce lime, generally multiple kilns are used to produce in parallel at the same time to improve production efficiency. When performing gas reversing between the calcining kiln chamber and the regenerative kiln chamber of each kiln, if the gas consumption of multiple kilns is large, and the distance from the gas generating device is close or there is no medium storage at the outlet pipeline of the gas generating device When installing equipment (such as gas cabinets), when two or more kilns perform gas reversing at the same time, it will have a greater impact on the inlet pressure of each gas branch pipe of the gas pressuriz...
