Abstract
The utility model discloses a sulfuric acid filter plant, and provides a filter for filtering impurity particles in a sulfuric acid refining process. The sulfuric acid filter plant comprises a filter tube, filter cloth, a depositing tube and an end cover. The filter tube is a pipeline, recycle acid of sulfuric acid flows through the pipeline, the depositing tube is disposed under the filter tube, is perpendicularly fixed onto the filter tube and is communicated with the filter tube, the filter cloth is arranged in the filter tube above the depositing tube and can completely cover the integral cross section of the filter tube, the end cover is disposed at the lower end of the depositing tube, and a lower port of the depositing tube is closed by the end cover. The sulfuric acid filter plant is simple in technology, convenient to use and easy to modify, impurity particles in the recycle acid can be removed completely and are prevented from damaging a magnetic pump, further, pollution accidents are indirectly prevented, and stable and continuous production of the sulfuric acid is guaranteed.
Description
Technical field
The utility model relates to gas washing in SA production, is specially impurity screening particulate filtration device in a kind of sulfuric acid treatment process.
Background technology
In the production preparation process of sulfuric acid; Have a large amount of sulfur trioxides and produce, sulfur trioxide is the acid anhydrides of sulfuric acid, meets water and can generate sulfuric acid; And sulfuric acid is the composition that harm is arranged in the acid rain most, so the sulfur trioxide of overflowing in the sulphuric acid process can cause very serious pollution to environment.In order to stop this pollution, be exactly need be in the production cycle of sulfuric acid in the process, sour pump adopts totally-enclosed lining teflon magnetic drive pump.Because the gap of magnetic drive pump lining teflon is very little, in a single day have impurity particle in the recycle acid and just be easy to the polytetrafluoroethylene (PTFE) cover is ground away, cause the damage of equipment, have to stop production.Therefore, need a kind of device to filter out, guarantee the ordinary production of equipment getting impurity particle in the recycle acid.
The utility model content
The technical problem that the utility model solved is to provide a kind of sulfuric acid filter, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
The sulfuric acid filter comprises and filters body, filter cloth, deposited tube and end cap, wherein; Filter the pipeline that body is flowed through for the sulfuric acid recycle acid, deposited tube be arranged on filter body below, be vertically fixed on and filter on the body; The centre is interconnected, and said filter cloth is arranged in the filtration body of deposited tube top, can cover the whole cross section of filtering body fully; Said end cap is arranged on the lower end of deposited tube, and the lower port of deposited tube is closed.
The upper end of said filter cloth is fixed on deposited tube left side wall correspondence in the position of filtering body upside inside pipe wall; The lower end is fixed on the deposited tube right side wall and filters the position that body is connected; Cross section is a circular arc; Make things convenient for to get impurity particle in the filtration cycle acid, form eddy current again in the deposited tube, prevent impurity particle deposition caking.
In said deposited tube lower end, the inboard of end cap is provided with ring structure, prevents that recycle acid from flowing out from the end cap position, and said end cap is fixed on the deposited tube lower end through sealing bolt.
In the utility model, said filter cloth adopts the polytetrafluoroethylene (PTFE) filter cloth.
Beneficial effect: the utility model technology is simple, and is easy to use, and repacking can be removed the impurity particle in the recycle acid easily fully, prevents that it from causing damage to magnetic drive pump, and then the indirect generation that prevents contamination accident, ensured that stable the continuing of sulfuric acid produces.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Among the figure: filter body 1, filter cloth 2, sealing bolt 3, end cap 4, sealing ring 5, deposited tube 6.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Sulfuric acid filter referring to Fig. 1; Comprise and filter body 1, filter cloth 2, deposited tube 6 and end cap 4, and be arranged on the sealing ring 5 between end cap 4 and the deposited tube 6, deposited tube 6 be arranged on filter body 1 below; Be vertically fixed on and filter on the body 1; The centre is interconnected, and said filter cloth 2 is arranged in the filtration body 1 of deposited tube 6 tops, and end cap 4 is fixed on the lower end of deposited tube 1 through sealing bolt 3.
The utility model is when installing and using, and recycle acid flows into from the left end that filters body, through the filtration of filter cloth; Pure recycle acid flows out from filtering the body right-hand member, and the impurity particle in the recycle acid is all leached by filter cloth, along with constantly washing away of recycle acid; Impurity particle falls in the deposited tube in the effect of self gravitation; Because the eddy current that the filter cloth structure is brought makes to be unlikely to impurity particle constantly motion in deposited tube at the deposition caking.
In the utility model, the bottom of deposited tube is provided with end cap, and the staff just can regularly open end cap, and the impurity particle that deposits in the deposited tube is cleared up.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
