Abstract
The invention provides a circumferential spiral tower tray for a gas washing tower, a gas cleaning device and application thereof. The circumferential spiral tower tray (10) comprises a spray column inlet pipeline (202), a spray column (206) and a spiral tower tray main body (102), wherein the spray column inlet pipeline (202) is arranged on one side of the upper part of a gas washing tower (1.2) and is basically perpendicular to walls (12 and 22) of the gas washing tower (1.2); the spray column inlet pipeline (202) further comprises an spray column inlet (204) which extends out of the wall of the gas washing tower (1.2); the spray column (206) is connected with the spray column inlet pipeline (202) at the approximate center of the gas washing tower (1.2) in a basically perpendicular mode; the circumference of the spray column (206) is uniformly distributed with a plurality of spray holes (208); the inner side of the spiral tower tray main body (102) is arranged in an upward spiral mode around the outer side of the spray column (206) from the lower end edge (104); and the outer side of the spiral tower tray main body (102) is connected with the inner walls (12 and 22) of the gas washing tower (1.2).
Description
technical field [0001] The present invention generally relates to the technical field of coal gasification, and specifically relates to a combined spiral tray for high-efficiency washing and purification of coal gas, a gas purification device including it and its application, especially for coal, petroleum coke, biomass, and combustible industries. A purification process and device for coal gas produced by pressurized gasification of waste as raw material and its application. Background technique [0002] In the pressurized gasification gas that uses coal, petroleum coke, biomass, and combustible industrial waste as raw materials, in addition to CO and H 2 In addition to other active ingredients, it also contains CO 2 、H 2 O, H 2 S, COS, CH 4 , N 2 , Ar, NH 3 , HCN, HCl, HCOOH and ash and other components, the purpose of the preliminary purification is to remove the NH 3 , HCN, HCl, HCOOH and ash, etc., for civil use and further transformation and removal of CO 2 、H ...
