Description

Technical Field

[0001] The utility model relates to the technical field of gasifiers, in particular to a smoke and pulverized coal conversion feeding device for a gasifier. Background Art

[0002] Gasifier refers to a reaction furnace used to produce coal gas, water gas and semi-water gas. The furnace body is cylindrical, the outer shell is made of steel plate or brick, lined with refractory bricks, and equipped with charging equipment, blast pipes and gas pipes. According to the structure, it can be divided into mechanical generator, step generator, generator with rotating furnace body and two-stage generator. According to the process, it can be divided into fixed bed or fluidized bed gasifier.

[0003] In the smoke-pulverized coal conversion charging device of the coal gasifier with patent publication number CN2799561Y, it is proposed that "the scattered smoke-pulverized coal is first closed and heated and sintered to remove smoke and form blocks, and then sintered into semi-coke that can be used as raw material for the coal gasifier. Then it is directly and closedly put into the coal gasifier for gas production. Through closed charging and closed heating, it is avoided that the coke oven is directly connected to the outside air through the charging bin, and the coal gasifier is directly connected to the coke oven and the outside air, so that the leakage of combustible gas in the coke oven and the coal gasifier can be effectively prevented, and the continuous and smooth progress of gas production is ensured."

[0004] However, the above device still has certain shortcomings when used. In the comparative scheme, the scattered smoke powder coal is sintered in advance and then put into the gasifier for gas production;

[0005] This feeding method does not have a guiding structure. When there is a lot of coal, it will accumulate in the coking furnace, causing some of the coal to be difficult to leak out, resulting in blockage of the pulverized coal when it enters the gasifier, thereby affecting the production efficiency of the gasifier.

[0024] By setting up an anti-clogging feeding structure 6, the electric push rod 18 and the closing valve 19 inside the feed barrel 10 and the discharge barrel 12 are used to open and close independently, so as to realize the closed feeding and closed heating of the pulverized coal. In combination with the continuous rotation of the guide rod 17 inside the feed barrel 10 and the discharge barrel 12, a hole gap can be formed in the pulverized coal at the center position of the feed barrel 10 and the discharge barrel 12, so as to speed up the leakage speed of the pulverized coal and avoid blockage during feeding, thereby ensuring the production efficiency of the gas generator.

[0025] Specifically, a bracket 3 is movably connected between the base 1 and the generator body 2 , and a recovery box 4 is provided on the top of the base 1 , and the recovery box 4 is located below the generator body 2 .

[0026] In this embodiment, the bracket 3 can be used to stably connect the generator body 2 and the base 1, and the recovery box 4 can be used to recover the materials produced in the generator body 2. The principle of the generator body 2 has been proposed in a double bell coal feeding mechanism for a gas generator with patent publication number CN112980511B, and will not be described here.

[0027] Specifically, the mounting structure 5 includes a back plate 7, which is connected to the surface of the base 1. A mounting half ring 8 is provided on the front side of the back plate 7.

[0028] In this embodiment, the anti-clogging feeding structure 6 can be quickly assembled and disassembled by using the mounting half ring 8 and the fixing half ring 9.

[0029] When in use, first open the top cover 14, then put the pulverized coal into the feed barrel 10, and then put the top cover 14 back to the top of the feed barrel 10, so that the top of the feed barrel 10 is closed, and then start the electric push rod 18, so that the electric push rod 18 drives the closing valve 19 to be gradually stored in the driving groove 15, so that the connecting port 20 at the bottom of the feed barrel 10 is opened, and then the guide rod 17 is started by an external power supply to rotate, so that the pulverized coal leaks down along the rotation direction of the guide rod 17, so that the pulverized coal in the feed barrel 10 falls into the coking furnace structure 11, and then the coking furnace structure 11 is started, and the coking furnace heats the pulverized coal in a closed manner to sinter it into semi-coke, and the working principle of the coking furnace structure 11 has been described in detail in the pulverized coal conversion and feeding device of the coal gasifier with patent publication number CN2799561Y, which will not be expanded here;

[0031] Then, the electric push rod 18 is started again, so that the closing valve 19 moves, so that the connecting port 20 at the top of the discharge barrel 12 is closed and the connecting port 20 at the bottom is opened, and then the guide rod 17 is started by an external power supply, so that the smoke and pulverized coal leaks down along the rotation direction of the guide rod 17, so that the smoke and pulverized coal in the discharge barrel 12 enters the interior of the generator body 2 through the connecting port 20 at the bottom of the discharge barrel 12 and along the direction of the introduction channel 13

[0032] In summary, the smoke and pulverized coal conversion feeding device of the gasifier, by setting an anti-blocking feeding structure 6, uses the electric push rod 18 and the closing valve 19 inside the feed barrel 10 and the discharge barrel 12 to adopt independent opening and closing, thereby realizing closed feeding and closed heating of the smoke and pulverized coal, and then cooperates with the continuous rotation of the guide rod 17 inside the feed barrel 10 and the discharge barrel 12, so that the smoke and pulverized coal at the center position inside the feed barrel 10 and the discharge barrel 12 can form a hole gap, so as to speed up the leakage speed of the smoke and pulverized coal and avoid blockage during feeding, thereby ensuring the production efficiency of the gasifier.
