Background technology
In sulphuric acid process, acid making system need add water to the pump groove when doing suction operation production sulfuric acid, and present most of enterprise is a method of taking directly to add to the pump groove water.Use this method,, be easy to generate a large amount of heat when adding water owing to be the concentrated sulfuric acid in the pump groove; Acid can produce a large amount of acid mists with water in cohesive process, acid mixing device is advanced sour threeway, acid inlet tube and water inlet pipe cause very big corrosion, and equipment is because corrosion; Shorten service life, damages easily.And it is cast iron pipe that existing acid mixing device advances sour threeway, and water inlet pipe is the SS920 pipe, and not anti-dilute sulfuric acid of a concentrated sulfuric acid resistant and acid mist are corroded easily.
The utility model content
The purpose of the utility model is to provide the concentrated sulfuric acid acid mixing device of a kind of acid mist of effectively avoiding producing in the sulphuric acid process to equipment corrosion.
The technical scheme that the utility model adopted is:
A kind of concentrated sulfuric acid acid mixing device comprises that acid mixing device advances sour threeway, acid inlet tube, water inlet pipe and pump groove, also comprises the water seal cover, and said water seal cover is arranged on the top that acid mixing device advances sour threeway; Said water inlet pipe comprises first water inlet pipe and second water inlet pipe; One end of said first water inlet pipe is connected with inlet valve, and the other end stretches into the inside of said water seal cover; Said second water inlet pipe runs through acid mixing device and advances sour threeway, and an end stretches into the inside of said water seal cover, and the other end stretches into below the liquid level of pump groove; Said second water inlet pipe upper end is stretched into the inner entrance height of water seal cover and is higher than the freeboard that said first water inlet pipe stretches into water seal cover inside.
The material that said acid mixing device advances sour threeway is the stainless steel lining four fluorine tube.
The material of said water inlet pipe is a four fluorine tube.
The material of said first water inlet pipe is the material of ordinary tap water water inlet pipe.
The concentrated sulfuric acid acid mixing device that the utility model provides, simple in structure, easy to operate, and changed material, the acid mist that can avoid effectively producing in the diluting concentrated sulfuric acid process prolongs the service life of equipment to advancing the corrosion of sour threeway and water inlet pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-first water inlet pipe, the 2-acid inlet tube, 3-water seal cover, the 4-acid mixing device advances sour threeway, 5-flange, 6-second water inlet pipe, 7-pump groove, 8-flange, 9-flange, 10-inlet valve.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof the utility model is described further.
A kind of concentrated sulfuric acid acid mixing device comprises that acid mixing device advances sour threeway 4, and the upper and lower that acid mixing device advances sour threeway 4 is connected with flange 5 and flange 8 respectively, advances the top placement of sour threeway 4 or is connected with water seal cover 3 with flange 5 at acid mixing device; The lid sealing of flange 9 adpting flanges can be used in the top of water seal cover 3, also direct welded seal.First water inlet pipe 1 is the ordinary tap water water inlet pipe, and an end is connected with inlet valve 10, and the other end stretches into the inside of water seal cover 3; Second water inlet pipe 6 runs through acid mixing device and advances sour threeway 4, and the inside of water seal cover 3 is stretched in the upper end, and the following position of sulfuric acid liquid level of pump groove 7 is stretched in the lower end; Second water inlet pipe 6 closely cooperates with flange 5, and between the flange 8 annular gap is arranged, and is convenient to pass through from the concentrated sulfuric acid that acid inlet tube 2 flows into the inside of its annular gap inflow pump groove 7.First water inlet pipe 1 can be that welding or flange are connected with second water inlet pipe 6 and the junction of water seal cover 3.Second water inlet pipe, 6 upper ends are stretched into water seal cover 3 inner entrance heights and are higher than the freeboard that first water inlet pipe 1 stretches into water seal cover 3 inside, so just can reach the water seal effect of water seal cover 3.Do to inhale operation and produce the needed water of sulfuric acid and flow into water seal cover 3 through first water inlet pipe 1, when the height of the water seal cover 3 inner waters surface entrance height greater than second water inlet pipe, 6 upper ends, water is through second water inlet pipe, 6 inflow pump grooves 7.
The material that the prior art acid mixing device advances sour threeway 4 is a cast iron pipe, is easy to be corroded, and is replaced by 304 stainless steel inner lining four fluorine tubes and can prevents corrosion effectively.
The prior art water inlet pipe is a SS920 pipe that is directly led to pump groove 7 by running water pipe; Not anti-dilute sulfuric acid of concentrated sulfuric acid resistant and acid mist; Be easy to be corroded; The utility model is divided into two parts with water inlet pipe, and a part is common running water first water inlet pipe 1, and another part is second water inlet pipe 6 that directly contacts with sulfuric acid that adopts the four fluorine tube material.So both solve the etching problem of water inlet pipe, also taken into account the problem of production cost.
The course of work is following:
Open the inlet valve 10 of first water inlet pipe 1, running water flows in the water seal cover 3 through water inlet pipe 1, and the water of water seal cover 3 inside joins pump groove 7 inside through the water inlet of second water inlet pipe, 6 upper ends; The concentrated sulfuric acid gets into acid mixing device from acid inlet tube 2 and advances in the sour threeway 4, among the middle part and the annular gap inflow pump groove 7 between second water inlet pipe 6 through flange 8.A large amount of acid mists that the concentrated sulfuric acid and water produce in cohesive process, acid mist part middle part and the annular gap between second water inlet pipe 6 through flange 8 rises to acid mixing device and enters sour threeway 4 inside, and another part is on the top of pump groove 7.When do to inhale operation produce the needed water of sulfuric acid add enough after, close inlet valve 10, the first water inlet pipes 1 sealing cover 3 that stops to feed water and add water, the upper end water inlet of second water inlet pipe 6 also stops to add water to pump groove 7.Even there is a spot of acid mist to rise to water seal cover 3 inside through the bottom of stretching into second water inlet pipe 6 below pump groove 7 liquid levels; Also can be in the 3 inner dilutions of water seal cover; Thereby first water inlet pipe 1 is thoroughly separated with acid mist, and the acid mist that has formed when having stopped to add water is to first water inlet pipe 1 and follow-up Corrosion of Pipeline thereof.
