Abstract

The utility model discloses an electrolytic bath for exhausting acid mist. The electrolytic bath is at least provided with an embedded or external acid mist exhaust pipeline, wherein the exhaust pipeline is arranged above the electrolyte surface in the electrolytic bath and communicated with an inner chamber of the electrolytic bath by small vents. The electrolytic bath disclosed by the utility model has a good acid mist exhaust effect and has the characteristics of being reasonable in structural design, simple and convenient, and causing no influences to technological operation.

Description

A kind of electrolyzer for the acid mist pump drainage

Technical field

The utility model belongs to the electrolyzer equipment manufacturing technology field of non-ferrous metal industry, particularly, relates to a kind of electrolyzer for the acid mist pump drainage.

Background technology

In the non-ferrous metal wet smelting process, the uncovered liquid level of electrolyzer top can a large amount of acid mist of effusion.The gas that electrolysis, electrolytic deposition process produce mainly contains hydrogenchloride, chlorine, oxygen, hydrogen etc.These gases can adhere to the acid drop liquid level of overflowing together, form acid mist in air, and steel systeming equipment and operator ' s health bring serious harm in the workshop thereby give.

At present the effective means of control acid mist is at the electrolysis groove face exhaust hood to be installed, as patent CN 202688461 U, CN 201826033 U etc.But, according to processing condition and workman's operational requirement of electrolysis, electrodeposition, above the electrolyzer groove face, need to go out the dress pole plate continually, detect short circuit, wash away operations such as bus.After groove face covers exhaust hood, then need to lift by crane continually cover, bring greatly inconvenience to operation, and increased working strength of workers.In addition, exhaust hood mostly is corrosion resistant glass reinforced plastic material greatly, and there is the serious aging problem in life-time service, can increase the production cost of enterprise during replacing.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of pump drainage acid mist effective, do not influence technological operation, reasonable in design, easy electrolyzer.

The utility model is to realize by following technical scheme: a kind of electrolyzer for the acid mist pump drainage is provided with an embedded or external acid mist pump drainage pipeline at least on the described cell wall; This pump drainage pipeline is arranged in the electrolysis liquid surface top of described electrolyzer and is communicated with the electrolyzer inner chamber by airing hole.

The embedded form of described pump drainage pipeline on described cell wall adopts whole embedded or local embedded.

Described pump drainage pipeline is placed on upper edge or the inboard of described cell wall.

The utility model structure is effective to the acid mist pump drainage, and is safe and reliable to operation, greatly improved workshop condition.In addition, the utility model reasonable in design is easy, and the mode that adopts electrolysis flute length sidewall one or both sides that the pump drainage pipeline is set has substituted exhaust hood traditionally, has saved to take up room, and the technological operation of workshop groove face is had no effect.

Description of drawings

Fig. 1, Fig. 2 are that the utility model is at the structural representation of each embedded one or two pump drainage pipeline of electrolysis flute length sidewall both sides;

Fig. 3, Fig. 4 are that the pump drainage pipeline is in the whole embedded or local embedded diagrammatic cross-section of electrolysis flute length sidewall;

Fig. 5, Fig. 6 are that the utility model is at the structural representation of each external one or two pump drainage pipeline of electrolysis flute length sidewall both sides.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.Should be understood that following embodiment is only for explanation the utility model but not for limiting scope of the present utility model.

Embodiment 1, with reference to Fig. 1, and a kind of electrolyzer for the acid mist pump drainage, it is made of long sidewall, short sidewall, base plate at least, and 1 liang of inboard of described electrolysis flute length sidewall respectively is provided with an embedded acid mist pump drainage pipeline 2; This pump drainage pipeline 2 is positioned at the electrolysis liquid surface top; Described pump drainage pipeline 2 is communicated with the electrolyzer inner chamber by airing hole 3, and the position, termination of pump drainage pipeline 2 connects with extraneous pipeline and induced draft fan, to realize the acid mist pump drainage of electrolysis liquid surface top.Pump drainage pipeline 2 described in this example is whole embedded form, and specifically with reference to Fig. 3, in addition, described pump drainage pipeline 2 also can adopt the part embedded in the embedded form of electrolysis flute length sidewall 1, specifically with reference to Fig. 4.Pump drainage pipeline 2 inner chambers are that other Any shape with cavity such as circle, rectangle all can.

In addition, according to the electrolysis process difference, when less or groove face is narrower when effusion acid mist amount, can be only at the side design pump drainage pipeline 2 of electrolysis flute length sidewall 1.

Embodiment 2, with reference to Fig. 2,1 liang of inboard of the sidewall of electrolysis flute length described in this embodiment respectively is provided with two embedded acid mist pump drainage pipelines 2 of series connection, two pump drainage pipelines, 2 adjacent end portions on long sidewall 1 one sides are provided with pipe plug and the pump drainage air-flow in two pump drainage pipelines 2 are flowed out to rightabout short sidewall 4 separately, this set is applicable to the electrolyzer that length is long, from two while pump drainage of sidewall, more even along long sidewall direction acid mist pump drainage.Surplus with embodiment 1.

Embodiment 3, and with reference to Fig. 5, the sidewall of electrolysis flute length described in this embodiment 1 both sides respectively are provided with an external acid mist pump drainage pipeline 2, and outer seated position is for long inside sidewalls, and is surplus with embodiment 1.

Embodiment 4, and with reference to Fig. 6, the sidewall of electrolysis flute length described in this embodiment 1 both sides respectively are provided with two acid mist pump drainage pipelines 2 that series connection is external, and outer seated position is long sidewall upper edge, and all the other are fully with embodiment 2.

The utility model structure is effective to the acid mist pump drainage, and the technological operation of workshop groove face is had no effect.Can replace existing exhaust hood fully aspect the acid mist pump drainage in non-ferrous metal hydrometallurgy field.
