Gas safety detection system and method for lithium battery rotary kiln and medium

Abstract

The embodiment of the invention is suitable for the field of lithium battery rotary kilns, and provides a gas safety detection system and method for a lithium battery rotary kiln and a medium. The system comprises a first temperature module, a second temperature module, a first pressure module and a second pressure module which are arranged in the kiln, and a calculation module which calculates the temperature difference and the pressure difference inside and outside the kiln; a temperature difference and pressure difference relation model is stored in the server, the rotary kiln heating system is used for heating or cooling a rotary kiln, and the valve module is used for controlling the opening degree of an exhaust port of the rotary kiln. And based on the relation model and the real-time temperature and pressure inside and outside the kiln, the rotary kiln heating system and the valve module are controlled to adjust the temperature and the pressure in the rotary kiln, and the pressure in the kiln is adjusted to the normal level on the premise that the ratio of the temperature difference to the pressure is kept unchanged or fluctuates within a certain range, so that the safety of gas in the kiln is improved.

Description

technical field [0001] The application belongs to the field of lithium battery rotary kiln, and in particular relates to a gas safety detection system, method and medium of a lithium battery rotary kiln. Background technique [0002] Rotary kiln In many production industries such as building materials, metallurgy, chemical industry, environmental protection, etc., rotary cylinder equipment is widely used for mechanical, physical or chemical treatment of solid materials. This type of equipment is called rotary kiln. The application of the rotary kiln originated from cement production. In 1824, the British cement worker J Asp invented the earth shaft kiln with intermittent operation; Eransome) invented the rotary kiln, and put it into production after obtaining patents in Britain and the United States, and soon gained considerable economic benefits. The invention of the rotary kiln led to the rapid development of the cement industry, and at the same time promoted people's res...

AI Technical Summary

Problems solved by technology

[0004] 1) The pressure has a direct impact on the temperature in the kiln. If the pressure changes, the critical temperature in the normal working state of the kiln will change, thereby affecting the normal operation of the kiln;

[0005] 2) If there is a sudden change in pressure, forcibly reducing the pressure through pressure relief will increase the safety hazard of the exhaust port, and it is very likely that the exhaust port will collapse, or even fry the kiln.
