Abstract
The invention relates to a pot-type furnace flame path temperature automatic control device. The pot-type furnace temperature automatic control device is formed in a way that front wall volatile matter is sent to an inlet of a first layer flame path through a front wall pipeline, the front wall pipeline is provided with an electrically operated valve, the rear wall volatile matter is sent to the front ends of a second layer flame path and a fourth layer flame path through a rear wall pipeline, the rear wall pipeline is provided with an electrically operated valve, the tail ends of the first layer flame path, the second layer flame path and the fourth layer flame path are respectively provided with a thermocouple, each thermocouple is connected with a temperature transmitter, the temperature transmitter is connected with a central controller, and the central controller is connected with the electrically operated valves. The pot-type furnace temperature automatic control device is advantaged in that in dependence on the detected temperature of the flame paths, the distribution proportion of volatile matter entering the flame paths is automatically controlled, furthermore the temperature of the first layer flame path, the second layer flame path and the fourth layer flame path are controlled, and finally the flame path temperature distribution is controlled. Operationally, the labor intensity of workers is reduced, and the production stability, the product quality and the thermal efficiency of the pot-type furnace are improved.
Description
Technical field
The present invention relates to a kind of automatic temperature control, particularly relate to the pot type burner fire path temperature automaton that carbon industry produces aluminium anode, negative electrode, electrode and charcoal element graphitized material.
Background technology
Can-type calcine furnace is low mainly due to carbon burnt loss, production process and constant product quality well gradually at calcining petroleum coke market dominate, particularly aluminium anode calcining workshop section.But pot type burner also exists larger problem, namely automatization level is low, or even does not almost control.Pot type burner product depends on hopper Temperature Distribution, and hopper temperature depends on the length of flame in quirk and Temperature Distribution.At present, depend on manual intervention and knowhow completely in the production of pot type burner for the control of temperature, not only labour intensity is large, and required temperature adjustment post is many, and temperature regulates not in time, is inaccurate, has had a strong impact on stability and the converter life of product quality.Therefore develop pot type burner fire path temperature automatic control system and can not only improve furnace thermal efficiency, more can ensure that product quality and stove run more stable, extend stove service life.
Summary of the invention
The present invention is a kind of pot type burner automatic temperature control proposed to solve the problem, its objective is and well control fugitive constituent reasonable distribution in quirk, thus control quirk flame length and Temperature Distribution, improve pot type burner production stability and the thermal efficiency.
For reaching above-mentioned purpose pot type burner automatic temperature control of the present invention, be made up of following manner: front wall fugitive constituent delivers to the entrance of first floor quirk by front wall pipeline, front wall pipeline is provided with motor-driven valve, rear wall fugitive constituent delivers to second layer quirk and the 4th layer of quirk front end by rear wall coil road, and motor-driven valve is provided with on rear wall coil road, thermocouple is respectively equipped with at first floor quirk, second layer quirk and the 4th layer of quirk end, each thermocouple is connected with a temperature transmitter, temperature transmitter is connected with central controller, and central controller is connected with motor-driven valve.
Motor-driven valve is electric butterfly valve.
When fluctuation appears in stove fire path temperature, thermocouple detected temperatures, delivers to central controller by signal by temperature transmitter, send instruction to motor-driven valve, regulate aperture, thus regulate the fugitive constituent flow entering first floor quirk, second layer quirk and the 4th layer of quirk, thus realize the control of temperature.
Thermocouple required precision ± 1 DEG C.
Central controller is PID feedback controller.
Advantageous effect of the present invention:
The present invention can enter the fugitive constituent allocation proportion of quirk by the temperature automatic control detected by quirk, and then controls the temperature of the quirk first floor, two layers and four layers, the final Temperature Distribution controlling quirk.Operation reduces labor strength, improves pot type burner production stability, product quality and the thermal efficiency.

Motor-driven valve is electric butterfly valve.
When there is fluctuation in stove fire path temperature, thermocouple 1 detected temperatures, signal is delivered to central controller 3 by temperature transmitter 2, send instruction to motor-driven valve 4, regulate aperture, thus regulate the fugitive constituent flow entering first floor quirk, second layer quirk and the 4th layer of quirk, thus realize the control of temperature.
Thermocouple 1 required precision ± 1 DEG C.
Central controller 3 is PID feedback controller.
