Deodorizing device for acid and alkaline gas from reaction kettle

Abstract

The invention discloses a deodorizing device for acid and alkaline gas from a reaction kettle. The deodorizing device comprises the reaction kettle, a draft fan, a deodorizing tank and an online pH monitor, wherein the deodorizing tank comprises a chemical spraying tank and an adsorption tank; a buffer solution storage tank is mounted at the top end of the chemical spraying tank; a water inlet anda chemical inlet are formed in the top end of the buffer solution storage tank; a matching cap is mounted at the chemical inlet; a pH measuring pipe is arranged on the cap; strip-shaped openings parallel to the separating plate are formed in the top of the adsorption tank; adsorption screens are vertically placed at the strip-shaped openings; an gas exhausting port and a water draining port are formed in one surface, parallel to the separating plate, of the adsorption tank; a transmitter placing tube is vertically arranged at the top end of the water draining port; a transmitter is placed inthe transmitter placing tube; and the transmitter is used for transmitting a signal to the online pH monitor. The deodorizing device performs gas condensation, acid and alkaline neutralization and adsorptive deodorization on the acid and alkaline gas from the reaction kettle, is applicable to deodorization of the acid and alkaline gas, and reduces emission of the acid and alkaline gas.

Description

technical field [0001] The invention belongs to the technical field of deodorizing devices, in particular to a deodorizing device for acid-base gas in a reactor. Background technique [0002] The reaction kettle is a commonly used chemical reaction container. Due to chemical reactions, a large amount of odorous gases are often produced, such as ammonia and other acidic gases with pungent odors and sulfur dioxide and other acidic gases that pollute the environment, which will affect the surrounding environment. affect human health. [0003] Chinese patent document CN205833815U discloses a deodorizing device for a reactor, which only discharges the peculiar smell in the reactor through an induced draft fan, and the deodorizing effect is limited; Chinese patent document CN206454612U discloses a deodorizing adsorption device for a reactor, There is a deodorization adsorption device under the reaction kettle, and the gas in the product is sucked by the fan, so that it passes thr...

[0002] The reaction kettle is a commonly used chemical reaction container. Due to chemical reactions, a large amount of odorous gases are often produced, such as ammonia and other acidic gases with pungent odors and sulfur dioxide and other acidic gases that pollute the environment, which will affect the surrounding environment. impact on human health

[0003] Chinese patent document CN205833815U discloses a deodorizing device for a reactor, which only discharges the peculiar smell in the reactor through an induced draft fan, and the deodorizing effect is limited; Chinese patent document CN206454612U discloses a deodorizing adsorption device for a reactor, There is a deodorization adsorption device under the reaction kettle, and the gas in the product is sucked by the fan, so that it passes through the annular adsorption network, so as to realize the deodorization and adsorption treatment of the gas. However, only through the annular adsorption with activated carbon adsorption layer Adsorption by the net, due to the fast gas flow rate, its effect is limited

In addition, deodorization devices are usually not targeted to deodorize specific gases, so the deodorization effect is limited
