Washing device for Lurgi coal gasifier outlet sample gas pretreatment system

Abstract

The invention relates to the technical field of gasification furnaces, in particular to a washing device for a Lurgi coal gasifier outlet sample gas pretreatment system, which comprises a tank body with an open upper end and an open lower end , an upper flange cover and a lower flange cover, circumferential ring grooves are formed in the positions, corresponding to the edges of openings in the upper end and the lower end of the tank body, of the lower side face of the upper flange cover and the upper side face of the lower flange cover respectively, the upper flange cover and the lower flange cover are connected through a long screw rod, an air inlet, an air outlet and a water inlet which are communicated with the interior of the tank body are formed in the upper flange cover, and an air inlet pipe is arranged in the tank body. The upper end of the air inlet pipe is communicated with the air inlet, a water inlet ball valve is arranged at the position, corresponding to the water inlet, of the upper flange cover, the oil removal and pressure stabilization effects can be well achieved, and measurement sample gas is provided for a subsequent online monitoring system.

Description

technical field [0001] The invention relates to the technical field of gasifiers, in particular to a water washing device used in a sample gas pretreatment system at the outlet of a Lurgi coal gasifier. Background technique [0002] At present, crude gas from Lurgi furnace gasifier in the coal chemical industry has the characteristics of special gas composition, high oil content, different processes, and being in an explosion-proof area. The workload is heavy, the real-time performance is poor, and there are high security risks. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a water washing device for a sample gas pretreatment system at the outlet of a Lurgi coal gasifier. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a water washing device for the sample gas pretreatment system at the outlet of Lurgi coal gasifier, compris...
