Gas chilled water washing filter device

Abstract

The present invention provides a gas-chilled water-washing filter device, which comprises: a water-washing unit, the water-washing unit includes an inlet pipe and a water-washing pipe, and the top of the inlet pipe is connected to one end of the water-washing pipe , the inlet pipe is provided with a water injection port and a gas injection port; a gas filter decompression unit, one end of the gas filter decompression unit is connected to the other end of the water washing pipe, and the other end of the gas filter decompression unit is set There is an air outlet. The gas quenching water washing and filtering device completes dust removal and sulfur removal in one step, the equipment occupies a small area, is safer to use, and can suppress reverse reactions and increase product yield.

Description

Technical field [0001] The present invention belongs to the field of chemical reaction equipment and the device, and more particularly to a gas-cooling water washing filter. Background technique [0002] my country's domestic production capacity is limited, and it is impossible to meet the rapid growth of domestic demand. Therefore, the importance of imported gas in my country's natural gas consumption structure is also a great proportion. In 2018, the national natural gas production was 107.7 billion cubic meters, consumption of 147.1 billion cubic meters, supply and demand gap reached 39.4 billion cubic meters. From January to April 2013, my country's natural gas production was 40.2 billion cubic meters, an increase of 7.7% year-on-year, with an import of 17.1 billion cubic meters, an increase of 32.3%, and the substantial growth of imported gas sources indicated that the domestic gas source supply still can't keep up. The pace of growth. The same period of natural gas is 56.8 ...

Problems solved by technology

[0003] Traditional coal-to-methane gas needs to be catalyzed by catalyst, three-stage dedusting, and water washing in sequence. Catalysis and three-stage dedusting equipment occupy a large area, which is not conducive to the promotion of equipment integration

[0004] In the coal-to-methane gas process, the output product is a mixture of methane gas, water vapor, dust and sulfide. This product cannot be used in the future, and sulfur removal and dust removal are usually required. However, the sulfur removal and dust removal in the prior art The method is to filter the output products through the filter screen. Through actual use, it is found that the efficiency of dust removal and sulfur removal is low. In addition, the inventors found that when the dust removal of coal-to-gas products is carried out by traditional methods, methane reverse reaction is very easy to occur, resulting in methane gas production. rate reduction
