Abstract
The utility model provides a refined sulfuric acid filter, which comprises an inlet flange plate, a filter cartridge, an outlet flange plate, a filter component and an impurity removing end cap. The refined sulfuric acid filter is characterized in that the inlet flange plate and the outlet flange plate are mounted at two ends of the filter cartridge respectively, an inclined cylinder for holding the filter component is further arranged on the lower portion of the filter cartridge, the impurity removing end cap is mounted at the end opening of the inclined cylinder, the filter component comprises a polytetrafluoroethylene tube with a hole and polytetrafluoroethylene cloth lined in the polytetrafluoroethylene tube, the plane of a lower end opening of the filter component contacts with the impurity removing end cap, and two sides of an upper end opening of the filter component are inlaid into the upper inner wall and the lower inner wall of the filter cartridge respectively. The refined sulfuric acid filter has the advantages that impurity particles in recycle acid can be removed completely, the problem of abrasion of a magnetic pump caused by the impurity particles is solved thoroughly, production of refined sulfuric acid is stabilized, and benefits are created for enterprises.
Description
Technical field
The utility model belongs to the sulfuric acid preparation field, especially relates to a kind of POV filter.
Background technology
In the preparation process of POV, can produce a large amount of sulfur trioxides, sulfur trioxide is discharged in the atmosphere; Can cause environmental pollution again; In order to stop this pollution, just need be in POV production cycle 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 the polytetrafluoroethylene (PTFE) cover in the pump is ground away, cause the stopping production of POV.
Summary of the invention
The purpose of the utility model provides a kind of sulfuric acid filter of simple in structure, simple to operate, good filtration effect.
The technical scheme of the utility model is: a kind of POV filter; Comprise suction flange dish, filtration barrel body, outlet(discharge) flange dish, filter element and contaminant removal end cap; The two ends of said filtration barrel body are separately installed with suction flange dish and outlet(discharge) flange dish; Also be provided with the oblique cylinder that is used for laying filter element in the bottom of filtration barrel body; At oblique cylindrical port the contaminant removal end cap is installed; Said filter element comprises polyfluortetraethylene pipe and the teflon cloth of liner in polyfluortetraethylene pipe that has perforate, and filter element lower port plane contacts with the contaminant removal end cap, and the both sides of filter element port are embedded in respectively in the inwall of filtration barrel body upper and lower.
Further, between said filter element port and the filtration barrel body, and between filter element lower port and the contaminant removal end cap, also be respectively equipped with polytetrafluoroethylene sealing gasket.
Further, said teflon cloth is 40 order teflon cloth.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, can the impurity particle in the recycle acid be removed fully, thoroughly solve the problem of impurity particle wearing and tearing magnetic drive pumps, it is stable that refining acid is produced, and gives enterprise's create beneficial result.

The specific embodiment
As shown in Figure 1, the technical scheme of the utility model is:
A kind of POV filter; Comprise suction flange dish 1, filtration barrel body 2, outlet(discharge) flange dish 3, filter element 4 and contaminant removal end cap 5; The two ends of said filtration barrel body 2 are separately installed with suction flange dish 1 and outlet(discharge) flange dish 3; Also be provided with the oblique cylinder that is used for laying filter element 4 in the bottom of filtration barrel body 2; At oblique cylindrical port contaminant removal end cap 5 is installed; Said filter element 4 comprises polyfluortetraethylene pipe and the teflon cloth of liner in polyfluortetraethylene pipe that has perforate, and filter element 4 lower port planes contact with contaminant removal end cap 5, and the both sides of filter element 4 port are embedded in respectively in the inwall of filtration barrel body 2 upper and lowers.
In the present embodiment, between said filter element 4 port and the filtration barrel body 2, and between filter element 4 lower port and the contaminant removal end cap 5, also be respectively equipped with polytetrafluoroethylene sealing gasket 6.
Said teflon cloth is 40 order teflon cloth.
The course of work of this instance:
Prepare in the process at sulfuric acid; Recycle acid gets into filter element 4 through suction flange dish 1; And filter through the perforate and the teflon cloth of polyfluortetraethylene pipe on the filter element 4, impurity particle has been left in the filter element 4, and pure recycle acid flows out from outlet(discharge) flange dish 3.
Because the lower end of filter element 4 is equipped with contaminant removal end cap 5, we just can be regular opens contaminant removal end cap 5, and the impurity in the filter element 4 is cleared up.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (3)
