Abstract

The invention discloses a central tube multi-nozzle gas washer. The washer comprises a condensate spray pipe, one end of the condensate spray pipe is provided with a condensate inlet, the other end of the condensate spray pipe is used for being inserted into a crude syngas outlet of a gasifier, a sleeve which sleeves the condensate spray pipe is arranged on the periphery of the condensate spray pipe, one end of the sleeve is installed at the crude syngas outlet of the gasifier in a sealed mode, the other end of the sleeve is of a sealing structure, the end, provided with a condensate inlet, of the condensate spray pipe is installed on the sealing structure in a sealed mode, a gas outlet is formed in the sleeve wall surface, side nozzle assemblies perpendicular to the condensate spray pipe wall surface are arranged on the outer wall surface of the condensate spray pipe at intervals, and the side nozzle assemblies are located on the portion, extending into the sleeve and the crude syngas outlet of the gasifier, of the condensate spray pipe. High voltage process condensate and the crude syngas are sprayed in the perpendicular direction through the side nozzle assemblies, a flow field is optimized, the condensate and the syngas are mixed to be more uniform, the wetting effect is greatly improved, and fine ash is more likely to be removed at a downstream elution tower.

Description

technical field

[0001] The invention belongs to the technical field of chilled coal gasification, in particular to a central tube multi-nozzle gas scrubber. Background technique

[0002] In the chilled coal gasification process, the chilled high-temperature and high-pressure crude synthesis gas needs to be further processed to remove the coarse slag and fine ash entrained in the crude synthesis gas to meet the requirements of downstream devices. Generally, the crude syngas is pre-washed and wetted by a Venturi scrubber, and then the fine ash is removed by a scrubber. In order to ensure the pre-washing effect, a nozzle scrubber is usually added before the Venturi scrubber. The high-pressure process condensate is inserted into the crude synthesis gas pipeline through the nozzle, and sprayed into the crude synthesis gas in reverse, while the crude synthesis gas is wetted. , use the high-speed airflow of the nozzle to blow back part of the coarse slag accumulated in the synthes...
