Steel wire surface treatment defogging components

Abstract

The invention belongs to the technical field of gas purification, and provides a demisting assembly for steel wire surface treatment.The demisting assembly comprises a cover shell arranged on the upper portion of a pickling tank in a matched and buckled mode, a flow guide pipe arranged on the top of the cover shell in a communicated mode, a mist collecting tower arranged on the top of the flow guide pipe and a separating tower arranged at the side of the mist collecting tower side by side; the mist collecting tower and the separating tower are communicated through an air pipe, the side of the mist collecting tower is radially provided with a mist exhaust pipe, the inner end of the mist exhaust pipe extends to the middle of an inner cavity of the mist collecting tower and corresponds to the air pipe, and the outer end of the mist exhaust pipe is connected with a draught fan.According to the steel wire surface treating and demisting assembly, the structural design is reasonable, and concentration of acid mist can be achieved through the cover shell and the flow guide pipe, so that the continuously increased acid mist flows to the mist collecting tower through the flow guide pipe and is conveyed into the separating tower in a static state; no negative pressure influence can be caused to acid liquid in the pickling tank in the process, so that the acid mist between the pickling tank and the cover shell is in a static state; accordingly, the stability of the whole system is guaranteed, and excessive volatilization of the acid mist is avoided.

Description

technical field [0001] The invention belongs to the technical field of gas purification, and in particular relates to a defogging component for steel wire surface treatment. Background technique [0002] Steel wire needs to be pickled on the surface before galvanizing to remove impurities. However, the existing pickling tanks are usually open, resulting in a large amount of acid mist in the workshop, making the working environment extremely harsh. However, after installing a demisting device on the pickling tank, it cannot be demistered by high-pressure suction, which will lead to excessive volatilization of the pickling tank and waste of acid liquid. Therefore, how to collect and filter acid mist It is the technical problem to be solved in this application. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and deficiencies, and provide a steel wire surface treatment defogging assembly with reasonable and compa...
