Pot calciner thermoregulation control device and method

Abstract

The invention discloses a pot calciner thermoregulation control device and method. The device comprises a photoelectric temperature sensor installed on a flame channel of a pot calciner, air conditioners installed on inlets of air channels of the pot calciner and a negative pressure regulator installed on an outlet of a gathering flue of the pot calciner, the photoelectric temperature sensor, the air conditioners and the negative pressure regulator are electrically connected with a control unit of the pot calciner, and the control unit of the pot calciner is in communication with a remote client side. When real-time temperature, detected by the photoelectric temperature sensor, of the flame channel is not within the target temperature range, the control unit of the pot calciner directly sends an instruction, or the remote client side sends an instruction to the control unit of the pot calciner, then the control unit of the pot calciner sends the instruction to the air conditioners and the negative pressure regulator to regulate respective opening degrees and then regulate the combustion degree of volatile matter in the flame channel, the real-time temperature of the flame channel is automatically and accurately regulated to be within the target temperature range, and the automation degree of the pot calciner is improved.

Description

technical field [0001] The invention relates to the field of tank type calciner, in particular to a temperature adjustment control device and a temperature adjustment control method for the tank type calciner. Background technique [0002] At present, calcined petroleum coke is required in the fields of aluminum carbon products, graphite electrodes, carbon electrodes, recarburizers, and titanium smelting. The calcining equipment for petroleum coke mainly includes rotary kilns and tank calciners. Among them, the pot calciner is widely used in domestic carbon factories to produce calcined petroleum coke required for aluminum prebaked anodes due to its advantages of small burning loss, high calcining quality, and realization of calcining without external fuel. However, compared with the rotary kiln, the pot calciner still has the following obvious defects: the pot calciner has a low degree of automation, and the adjustment and control of the calcining temperature mainly depends...

Problems solved by technology

However, compared with the rotary kiln, the pot calciner still has the following obvious defects: the pot calciner has a low degree of automation, and the adjustment and control of the calcining temperature mainly depends on the experience of the workers. On the one hand, the temperature error of manual observation is large, and the temperature cannot be realized Accurate adjustment, and temperature is the main control factor of the true density of the main quality index of calcined petroleum coke, so the product quality is difficult to guarantee; The service life of the tank-type calciner; third, the low degree of automation of the tank-type calciner leads to a large amount of labor for workers and increased labor costs; fourth, the current shortage of high-tech temperature-adjusting workers makes it difficult for companies to invest in new production capacity to find outstanding talent
