Composite catalytic tannin extract method desulfurization device and its desulfurization process method

Abstract

The invention discloses a composite catalytic tannin extraction method desulfurization device and a desulfurization process method thereof. The desulfurization device includes a desulfurization tower and a regeneration tank, and the regeneration tank includes an outer cylinder, an inner cylinder and a cover cylinder. There is a sieve plate, a liquid storage chamber is formed between the outer cylinder and the inner cylinder, the outer cylinder is provided with a lean liquid port, the cover cylinder is provided with a sulfur foam port, and the outer cylinder is provided with a spray device (8) , the injection device includes a nozzle (13), a suction pipe (15), a throat pipe (16) and a diffuser pipe (17). The air self-suction port communicated with the suction chamber, and the inner wall of the suction pipe is provided with a spiral deflector (18) which can make the self-suction air form a vortex. The invention can not only greatly improve the desulfurization efficiency, but also effectively remove organic sulfur and inorganic sulfur, improve the activation of desulfurized rich liquid, slow down the growth of secondary salts, reduce the consumption of desulfurizers, catalysts and soda ash, save costs, and benefit Environmental friendly.

Description

technical field [0001] The invention relates to coke oven gas desulfurization equipment and a desulfurization process method. Background technique [0002] Coke oven gas is an important medium-to-high-value gas fuel produced in coking production. It can be used not only for steel production, but also for urban residents. It can also be used as a raw material for the production of synthetic ammonia, methanol and other chemical products. However, coke oven gas contains more harmful substances such as hydrogen sulfide, ammonia and hydrogen cyanide, which are toxic and corrosive to the human body and will cause serious pollution to the environment. Therefore, coke oven gas must be desulfurized and decyanidated. At present, the liquid is mainly used to remove hydrogen sulfide and hydrogen cyanide in the gas, and the OTS desulfurization catalyst (binuclear phthalocyanine cobalt sulfonate organic polymer compound) is used to cooperate with tannin extract and vanadium pentoxide.

Problems solved by technology

At present, the main problem of the ejector is that the formed vacuum degree is not high, and the amount of inhaled air is small, so that the desulfurization rich liquid cannot be fully contacted with the self-priming air quickly and fully, so that the regeneration effect of the desulfurization rich liquid is poor, which affects the desulfurization treatment effect of the desulfurization tower. and tower blockage
