Abstract

The present invention relates to a kind of pot type burner fire path temperature automaton.Pot type burner automatic temperature control, is made up of following manner:Front wall fugitive constituent is sent to the entrance of first floor quirk by front wall pipeline, front wall pipeline is provided with motor-driven valve, wall fugitive constituent is sent to second layer quirk and the 4th layer of quirk front end by rear wall coil road afterwards, and motor-driven valve is provided with rear wall coil road, thermocouple is respectively equipped with first floor quirk, second layer quirk and the 4th layer of quirk end, each thermocouple is connected with a temperature transmitter, and temperature transmitter is connected with central controller, and central controller is connected with motor-driven valve.Advantages of the present invention effect:The present invention can enter the fugitive constituent allocation proportion of quirk according to the temperature automatic control detected by quirk, and then control the temperature of the quirk first floor, two layers and four layers, the final Temperature Distribution for controlling quirk.Labor strength is reduced in operation, improves pot type burner production stability, product quality and the thermal efficiency.

Description

Pot type burner automatic temperature control
Technical field
The present invention relates to a kind of automatic temperature control, more particularly to carbon industry production aluminium anode, negative electrode, electrode And the pot type burner fire path temperature automaton of charcoal element graphitized material.
Background technology
Can-type calcine furnace is mainly due to carbon burnt loss is low, production process and product quality stability are well gradually forged in petroleum coke Burn market and occupy leading position, particularly aluminium anode calcining workshop section.But pot type burner there is also it is larger the problem of, that is, automate Low SI, almost do not control even.Pot type burner product depends on hopper Temperature Distribution, and hopper temperature depends on quirk The interior length of flame and Temperature Distribution.At present, the control in the production of pot type burner for temperature depend entirely on manual intervention and Knowhow, not only labor intensity is big, and required temperature adjustment post is more, and temperature adjustment is not in time, is inaccurate, and has a strong impact on The stability and converter life of product quality.Therefore exploitation pot type burner fire path temperature automatic control system can not only improve stove heat Efficiency, it more can guarantee that product quality and stove operation are more stable, extend stove service life.
The content of the invention
The present invention is a kind of pot type burner automatic temperature control in order to solve the above problems and propose, the purpose is to very Fugitive constituent reasonable distribution in good control quirk, so as to control quirk flame length and Temperature Distribution, improve pot type burner production Stability and the thermal efficiency.
Pot type burner automatic temperature control of the present invention for the above-mentioned purpose, is made up of following manner:Front wall fugitive constituent leads to The entrance that front wall pipeline is sent to first floor quirk is crossed, front wall pipeline is provided with motor-driven valve, and rear wall fugitive constituent is sent to by rear wall coil road Second layer quirk and the 4th layer of quirk front end, and motor-driven valve is provided with rear wall coil road, in first floor quirk, second layer quirk and Four layers of quirk end are respectively equipped with thermocouple, and each thermocouple is connected with a temperature transmitter, and temperature transmitter is controlled with center Device connection processed, central controller are connected with motor-driven valve.
Motor-driven valve is electric butterfly valve.
When stove fire path temperature fluctuates, thermocouple detection temperature, signal is delivered into center by temperature transmitter Controller, instruction is sent to motor-driven valve, aperture is adjusted, so as to adjust into first floor quirk, second layer quirk and the 4th layer of quirk Fugitive constituent flow, so as to realize the control of temperature.
Thermocouple required precision ± 1 DEG C.
Central controller is PID/feedback controller.
Advantages of the present invention effect:
The present invention can enter the fugitive constituent allocation proportion of quirk according to the temperature automatic control detected by quirk, and then control The temperature of the quirk first floor processed, two layers and four layers, the final Temperature Distribution for controlling quirk.Labor strength is reduced in operation, Improve pot type burner production stability, product quality and the thermal efficiency.

Fig. 1 is the control device schematic diagram of the present invention.
In figure:1st, thermocouple;2nd, temperature transmitter;3rd, central controller;4th, motor-driven valve;5th, front wall pipeline;6th, rear wall coil Road.
Embodiment
Embodiments of the invention combination accompanying drawing is described in detail in below, but protection scope of the present invention is not by embodiment Limited.
Pot type burner automatic temperature control of the present invention as shown in the figure, is made up of following manner:Front wall fugitive constituent passes through preceding Wall coil road 5 is sent to the entrance of first floor quirk, and front wall pipeline is provided with motor-driven valve 4, and rear wall fugitive constituent is sent to by rear wall coil road 6 Two layers of quirk and the 4th layer of quirk front end, and motor-driven valve 4 is provided with rear wall coil road 6, in first floor quirk, second layer quirk and Four layers of quirk end are respectively equipped with thermocouple 1, and each thermocouple 1 is connected with a temperature transmitter 2, and temperature transmitter 2 is with Centre controller 3 is connected, and central controller 3 is connected with motor-driven valve 4.
Motor-driven valve is electric butterfly valve.
When stove fire path temperature fluctuates, the detection temperature of thermocouple 1, during signal is delivered to by temperature transmitter 2 Controller 3 is entreated, instruction is sent to motor-driven valve 4, aperture is adjusted, so as to adjust into first floor quirk, second layer quirk and the 4th layer The fugitive constituent flow of quirk, so as to realize the control of temperature.
Required precision ± 1 DEG C of thermocouple 1.
Central controller 3 is PID/feedback controller.
