Spray saturator for coke oven gas production

Abstract

The invention relates to the field of soot deamination equipment, and discloses a spray saturator for coke oven gas production, including a saturator body, an air inlet pipe, a spray chamber, a spray chamber, a spray channel, a spray head, Downcomer, full flow pipe and acid remover, the spray chamber is set in the body of the saturator to spray out ammonia gas from soot, the spray chamber is equipped with an adjustment box at the center, the The upper part of the soot in the spray chamber enters from the top of the side of the adjustment box. The spray saturator for coke oven gas production, through the design of the first soot pipe and the second soot pipe in the spray chamber, the soot on the upper and lower sides of the adjustment box in the spray chamber can be mixed with the The mother liquor of sulfuric acid sprayed out from the nozzle fully reacts, so that NH will not be generated due to excess sulfuric acid in the soot reaction above the spray chamber 4 HSO 4 Impurities, NH3 pages in the soot above the spray chamber can fully react with sulfuric acid to ensure a good deamination effect.

Description

technical field [0001] The invention relates to the field of soot deamination equipment, in particular to a spray saturator for coke oven gas production. Background technique [0002] The spray saturator is a deammonization equipment used in the process of purifying the gas produced in the coking plant and coal gas production. The spray saturator is divided into an upper section and a lower section. The upper section is the absorption chamber, and the lower section is the crystallization chamber. The absorption chamber is divided into three parts: the front chamber, the annular spray chamber and the rear chamber. The crystallization chamber is connected to the downcomer. The absorption chamber has a built-in acid remover, which is a cyclone separation structure, and is used to separate the mother liquor in the soot. [0003] However, the spray chamber 3 of the existing spray type saturator has a certain height value. When the soot enters the spray chamber 3, the shower head ...

Problems solved by technology

[0003] However, the spray chamber 3 of the existing spray type saturator has a certain height value. When the soot enters the spray chamber 3, the shower head 6 is located at the top of the shower chamber, which makes the soot above the spray chamber 3 and the shower head 6. The sprayed mother liquor is fully contacted and reacted, resulting in excessive mother liquor when the reaction is carried out above the spray chamber 3, and the product is NH 4 HSO 4 , leading to subsequent crystallization of NH 4 HSO 4 and (NH 4 ) 2 SO 4 Mixtures that affect (NH 4 ) 2 SO 4 Recycling production, but the soot below the spray chamber and the mother liquor sprayed from the nozzle 6 have not fully contacted and reacted, resulting in NH in the smoke 4 If the reaction is not complete, the deamination effect of soot is not good
