Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of carbon production tank furnace, and particularly relates to a volatile flow structure of tank furnace. BACKGROUND

[0002] Carbon enterprises use tank furnaces for calcination production to complete high-temperature modification of green petroleum coke and obtain cooked petroleum coke. The high-temperature modification process of green petroleum coke can precipitate volatile and other flammable gases. In order to effectively utilize the chemical energy in the volatiles, the traditional calcination production sets a volatile collection main channel communicated with the material tank at the upper part of the tank furnace to collect the volatiles escaping from the material tank and send them into the flue as fuel for the furnace body to burn and heat the material.

[0003] The volatile flow structure of the tank furnace mainly includes two types. One is a traditional volatile flow structure of tank furnace as shown in FIG. 1, which includes one main channel 1 and four auxiliary channels 1-1 arranged at the front and rear walls and communicated with the end of the material tank. This structure can cause uneven distribution of volatiles into the flue. The existing technology has improved the structure. The improved volatile flow structure of the tank furnace is as shown in FIG. 2, which cancels the four auxiliary channels and adds two edge channels 1-2 parallel to the main channel. Figure 1 Figure 2 Figure 3 is a longitudinal sectional view at the position of the front wall. The volatiles are precipitated from the inside of the material of the material tank 3, distributed into the first layer flue 13 through the main channel 1, the edge channel 1-2 and the volatile horizontal channel 6, and burned in the first layer flue 13 through the volatile vertical channel 5. Figure 2 However, whether it is the traditional tank furnace or the improved tank furnace, the volatile flow structure is arranged at the upper part of the tank furnace, which causes the temperature of the volatile collection channel to be low, and the volatiles are easy to condense and adhere to the wall of the collection channel to form solid attachments. With the cumulative effect of time, the volatile collection channel is gradually blocked, and the flow area becomes smaller and smaller, so manual cleaning of the volatile collection main channel is required. Usually, the cleaning period is half a month, and the cleaning process mainly uses compressed air to blow at the volatile horizontal cleaning hole 7 and the vertical cleaning hole 11. Not only is the operating environment temperature high, but also a large amount of harmful gas is generated, which is the last obstacle for the tank furnace to realize environmental protection production for calcination of petroleum coke.

[0004] SUMMARY In view of the above-mentioned shortcomings and deficiencies of the prior art, the present application provides a volatile flow structure of tank furnace. By canceling the main channel and the edge channel, volatile vertical channels are arranged at both sides of the ends of the material tank and directly connected with the volatile escape channels of the material tank. The volatiles directly enter the first layer flue through the volatile vertical channels after escaping from the material tank, which completely solves the problem of coking and blocking of volatile flow in the main channel due to cooling of volatiles, and realizes environmental protection production of the tank furnace.

[0005] ​​​

[0006] To achieve the above object, the main technical scheme adopted by the present application comprises:

[0007] A volatile matter flow structure of a tank furnace comprises a furnace body, a material tank arranged in the furnace body, and a first layer flue, further comprising a volatile matter vertical flue arranged in the furnace body, wherein the volatile matter vertical flue is arranged in the top brickwork of the first layer flue and is communicated with the first layer flue, and the other end of the volatile matter vertical flue is communicated with the material tank through a volatile matter escape outlet. The traditional and current volatile matter collection main flue of the tank furnace is cancelled by arranging the checker bricks communicated with the volatile matter escape outlet of the upper part of the material tank on the upper part of the first layer flue, so that the production and environmental protection problems caused by the coking and blocking of the traditional and current volatile matter main flue of the tank furnace are solved from the root.

[0008] Further, the top of the volatile matter vertical flue is provided with a volatile matter flow control device.

[0009] Further, the volatile matter vertical flue is composed of cover bricks and checker bricks, the checker bricks have a flow channel structure in the middle, and the cover bricks are arranged on the top of the flow channel of the checker bricks. The cover bricks are movable parts, and the length and width of the cover bricks are not less than the corresponding width and length of the checker bricks. The position of the cover bricks on the upper part of the checker bricks can be adjusted to control the flow of the volatile matter, which is beneficial to the uniform distribution of the volatile matter and further realizes the stable combustion of the flue.

[0010] Further, the volatile matter vertical flue is communicated with a vertical cleaning hole, and the position of the cover bricks is adjusted through the vertical cleaning hole. The position of the cover bricks can be adjusted through the vertical cleaning hole by using a tool, so as to adjust the flow area of the volatile matter vertical flue, control the flow of the volatile matter at different positions, and better match the production changes.

[0011] Further, the material tank is arranged between two first layer flues and is communicated with a material tank cleaning hole.

[0012] Further, four volatile matter vertical flues are arranged on each first layer flue, two material tanks are arranged between two adjacent first layer flues, and volatile matter vertical flues are arranged at the positions of the four corners of each material tank. This is beneficial to the escape of the volatile matter and makes the escape more uniform.

[0013] The present application has the following beneficial effects:

[0014] The volatile matter flow structure of the tank furnace of the present application is easy to implement. The traditional and current volatile matter collection main flue of the tank furnace is cancelled by arranging the checker bricks communicated with the volatile matter escape outlet of the upper part of the material tank on the upper part of the first layer flue, so that the production and environmental protection problems caused by the coking and blocking of the traditional and current volatile matter main flue of the tank furnace are solved from the root. The position of the cover bricks on the upper part of the checker bricks can be adjusted to control the flow of the volatile matter, which is beneficial to the uniform distribution of the volatile matter and further realizes the stable combustion of the flue.
