Description

Technical Field

[0001] This utility model relates to the field of energy processing technology, specifically to a processing equipment for producing water gas from coal. Background Technology

[0002] Water gas, a low-calorific-value gas, is mainly composed of hydrogen and carbon monoxide. Industrially, it is used as fuel and is also a raw material for the production of synthetic ammonia, methanol, dimethyl ether, and fuel oil. Its applications are very wide. Currently, most water gas production methods use fixed-bed gasifiers with high-quality anthracite lump coal or coke as raw materials. However, hydrogen sulfide gas is also generated during the production process. If not treated in time, it will not only harm human health but also seriously corrode equipment.

[0003] In recent years, with the further development of related technologies, the patent application document with application number 202020030216.3 proposed that "in the processing equipment for producing water gas from coal, the processed water gas is introduced into the inner cavity of the adsorption box through a conduit, and the diethanolamine aqueous solution in the adsorption box absorbs the hydrogen sulfide in the water gas. At the same time, the activated carbon filter element in the inner cavity of the secondary filtration box also plays the role of filtering trace amounts of hydrogen sulfide gas, thus achieving the effect of filtering hydrogen sulfide in the water gas." However, the process of diethanolamine aqueous solution absorbing hydrogen sulfide generates a large amount of waste heat, which still has an adverse effect on the overall processing environment. It can be seen that the existing technology has not completely solved the problems of the existing technology. Utility Model Content

[0030] Working principle:

[0031] Example 1

[0032] For the water gas produced by the existing equipment, it is guided to the interior of the solution treatment tank 1 through the gas guide pipe 9, so that the water gas is fully mixed with the diethanolamine aqueous solution placed in the solution treatment tank 1, and then the diethanolamine aqueous solution is used to absorb the hydrogen sulfide in the water gas.

[0033] After preliminary treatment, the water gas will enter the interior of the second treatment box 22 through the connecting pipe 4. Then, the activated carbon pre-placed inside the second treatment box 22 will be used to re-absorb the water gas, further eliminating the residual hydrogen sulfide in the water gas. The water gas after re-treatment will be transported to the storage container through the diversion pipe 8.

[0034] Regarding the waste heat generated by the absorption of hydrogen sulfide from water gas by the diethanolamine aqueous solution inside the solution processing tank 1, the water pump 6 can be started to pump external cold water into the semi-open U-shaped hollow plate 5. Multiple heat sinks 12 absorb the waste heat emitted by the solution processing tank 1 and then discharge it through the first drain solenoid valve pipe 7, thereby cooling the solution processing tank 1 and preventing the waste heat from affecting the processing environment.

[0035] Example 2

[0036] For the secondary utilization of waste heat, external cold water can be pumped into the semi-open U-shaped hollow plate 5 by water pump 6. Multiple heat sinks 12 can be used to absorb the waste heat emitted by the solution treatment tank 1. The resulting hot water is then turned off by closing the first drain solenoid valve pipe 7 and opening the third drain solenoid valve pipe 14. The hot water is then introduced into the annular space through the third drain solenoid valve pipe 14 to assist in heating the activated carbon inside the second treatment tank 22. The hot water is then discharged through the second drain solenoid valve pipe 10. The adsorption performance of the heated activated carbon is usually enhanced, which can better absorb the residual hydrogen sulfide in the water gas.
