Description

Technical Field

[0001] This utility model relates to the field of gas collection technology, and in particular to a diversion-type pyrolysis carbonization gas collection device. Background Technology

[0002] Pyrolysis carbonization is an important thermochemical conversion technology. It involves high-temperature heating of carbonaceous materials under anaerobic or oxygen-deficient conditions, with the presence of an inert gas as a protective atmosphere. During this process, the carbonaceous materials undergo complex chemical reactions, decomposing into various products, mainly including solid carbon, liquid tar, and gaseous products. However, toxic and usable gases are often generated during carbonization, necessitating their collection. A diversion-type pyrolysis carbonization gas collection device is a key component of the pyrolysis carbonization system. It is primarily used to collect the gases generated during the pyrolysis carbonization process. Structurally, it has different channels to achieve the diversion function. When the carbonaceous raw material is carbonized in the pyrolysis furnace, this diversion collection method helps in the subsequent purification and utilization of the gases. For example, the collected hydrogen and methane can be used as high-quality fuels for heating and power generation. However, excessively high gas temperatures during collection can damage the equipment, requiring cooling operations.

[0003] Existing gas cooling mechanisms consist of coolant, pipes, and bolts. These mechanisms primarily aim to lower the temperature of the high-temperature gases produced by pyrolysis. They typically operate on the principle of a heat exchanger, using a pipe-type heat exchanger where the high-temperature gas flows inside the pipes while a cooling medium surrounds it. As the high-temperature gas passes through these pipes, heat is transferred to the cooling medium through the pipe walls, thus lowering the gas temperature. This cooling mechanism effectively prevents damage to subsequent collection equipment caused by excessively high gas temperatures and allows some impurities and condensable gases that are gaseous at high temperatures to condense, facilitating subsequent separation and collection. For example, tar vapor can become liquid after cooling, thus better separating it from other gases. However, this type of cooling device cannot recycle the cooling medium, significantly increasing costs, and requires periodic replacement of the cooling medium, reducing the collection rate. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a diversion-type pyrolysis carbonization gas collection device, which aims to improve the existing technology where the cooling device cannot cool and recycle the cooling medium, greatly increasing the cost, and requiring regular replacement of the cooling medium, which reduces the collection rate.

An exhaust pipe is connected to the right side of the outer wall of the fixed cylinder.

[0008] As a further description of the above technical solution:

[0009] The front and rear ends of the second cooling box are provided with multiple square holes, and multiple filter screens are fixedly connected inside the second cooling box.

[0010] As a further description of the above technical solution:

[0011] The filter box has multiple filter screens fixedly connected inside, and the front side of the outer wall of the gas collecting bottle is connected to an outlet pipe.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the gas generated by carbonization first enters the cooling pipe through the second inlet pipe, and then is decelerated by the baffle plate. Then, the pump draws the coolant inside the second cooling tank into the inlet pipe through the liquid delivery pipe, and then enters the cylindrical hole in the first cooling tank through the inlet pipe. At this time, the coolant will cool the gas in the cooling pipe. Then, the cooled liquid flows back into the cooling tank through the liquid outlet pipe.

Then the air enters the fixed cylinder through the gap between the ring and the cylindrical plug, and finally is discharged through the exhaust pipe. This achieves the function of stabilizing the overall gas pressure and improving the overall safety by venting the air inside the bottle. Attached Figure Description

[0039] Specifically, the internal structure of the carbonization furnace 1 is fixedly connected to a filter screen 17, which ensures that impurities are effectively separated during the carbonization process, guaranteeing the purity of the carbonized products. In addition, an annular fixing block 24 is fixedly connected to the lower part of the outer wall of the carbonization furnace 1.

A square support block 25 is fixedly connected to the right side of the connecting bridge 23, and a base 22 is fixedly connected to its bottom. This design makes the center of gravity of the entire carbonization furnace 1 lower and the stability stronger. Finally, the top left side of the base 22 is fixedly connected to the bottom of the carbonization furnace 1. This connection method not only ensures the integrity of the device, but also facilitates the installation and movement of the equipment.

[0040] Working principle: First, the gas generated by carbonization enters the cooling pipe 4 through the second air inlet pipe 3. Then, the gas is slowed down by the gas baffle plate 10 inside the cooling pipe 4. Then, the booster pump 13 draws the coolant inside the second cooling tank 12 into the inlet pipe 7 through the liquid delivery pipe 11. The coolant then enters the cylindrical hole 9 inside the first cooling tank 6 through the inlet pipe 7. At this time, the coolant will cool the gas in the cooling pipe 4. Then, the cooled liquid flows back into the second cooling tank 12 through the outlet pipe 8. At this time, it is slowed down by the filter screen 15 and drips to the bottom of the second cooling tank 12. It is cooled down by the cold air entering through the square hole 14. At the same time, the cooled gas enters the gas collection bottle 18 through the outlet pipe 5. This realizes the function of cooling and collecting the collected gas and recycling the coolant.

[0041] When the gas collecting bottle 18 begins to fill with gas, the air inside will enter the filter box 202 through the inlet pipe 201, and then be filtered by the filter screen 16 inside the filter box 202. Subsequently, the cylindrical plug 205 is lifted and moved away from the ring 204. At the same time, the spring 203 is compressed, and then the air enters the fixed cylinder 207 through the gap between the ring 204 and the cylindrical plug 205. Finally, it is discharged through the exhaust pipe 208. When the gas pressure inside the bottle is balanced, the spring 203 pushes the cylindrical plug 205 back. At this time, the cylindrical plug 205 and the ring 204 are together, which realizes the function of stabilizing the overall gas pressure by venting the air inside the bottle and improving the overall safety.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
