Description

Hydrogen filter

Technical Field

The utility model relates to the field of gas filtering equipment, in particular to a hydrogen filter.

Background

With the development of hydrogen energy, hydrogen filters are increasingly used in hydrogen production and hydrogen application, and especially large-scale hydrogen power plants are widely used. Most of hydrogen filters in the current market are vertical and adopt a flange cover or end enclosure structure, so that hydrogen is easy to leak, the working steps for replacing filter elements are complicated, and the operation and maintenance time is long; in addition, the filter occupies a large area and is very difficult to hoist.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model provides the hydrogen filter which has the characteristics of convenience in filter element replacement and simplicity in operation and maintenance.

In order to achieve the purpose, the utility model adopts the technical scheme that:

a hydrogen filter comprises a shell, wherein openings are formed in two ends of the shell, the edge of the opening on the left side is welded into an inlet conical section, and the edge of the opening on the right side is welded into an outlet conical section; the other end of the inlet conical section is welded with an inlet flange; the other end of the outlet conical section is welded with an outlet flange; a support plate is welded at the opening at the right side of the shell; the supporting plate seals the right opening of the shell; the filter element is arranged in the shell and is detachably arranged on the support plate; the support plate is provided with an opening through which the filter element port can pass; the shell is characterized in that an exhaust port is welded on the upper surface of the shell, and a drain outlet is welded on the lower surface of the shell.

Furthermore, a lifting lug is welded on one side of the outer surface of the shell.

Further, the lifting lug is two.

Further, the shell is a hollow cylinder with two open ends.

Further, the number of the filter elements is at least one.

Further, the filter element is in threaded connection with the support plate.

Further, the fillet weld size of the support plate welded with the right opening of the shell is 8 mm.

Compared with the prior art, the utility model has the beneficial effects that:

according to the hydrogen filter disclosed by the utility model, the support plate is welded at the opening at the right side of the shell, so that hydrogen can be prevented from leaking, and the sealing property is good; the hydrogen filter is horizontally arranged, and the filter element and the support plate are detachably connected, so that the filter element is more convenient to replace; in addition, the inlet and the outlet of the hydrogen filter are on the same horizontal line, the on-site piping is more free and convenient, the hydrogen filter is integrally provided with no traditional flange cover sealing structure, and the hydrogen is not easy to leak.

in the figure: 1. an inlet flange; 2. an inlet cone section; 3. a housing; 4. lifting lugs; 5. an exhaust port; 6. an outlet cone section; 7. an outlet flange; 8. a support plate; 9. a sewage draining outlet; 10. a filter element; a. a hydrogen inlet; b. and (4) a hydrogen outlet.

Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings.

As shown in fig. 1, the hydrogen filter disclosed by the utility model comprises a shell 3, wherein the shell 3 is hollow, two ends of the shell are provided with openings, the edge of the left opening is welded into an inlet conical section 2, and the edge of the right opening is welded into an outlet conical section 6; an inlet flange 1 is welded at one end of the inlet conical section 2, which is far away from the shell 3; an outlet flange 7 is welded at one end of the outlet conical section 6, which is far away from the shell 3; a support plate 8 is welded at the opening at the right side of the shell 3; the supporting plate 8 seals the right opening of the shell 3; therefore, the high tightness can be ensured, and hydrogen is not easy to leak; the filter element 10 is arranged in the shell 3, the number of the filter elements 10 is at least one, and the filter elements 10 are detachably arranged on the support plate 8; the support plate 8 is provided with an opening for the filter element to pass through; the gas vent 5 has still been welded to the 3 upper surface of casing, and lower surface welding has drain 9, and the welding of surface one side has lug 4.

Preferably, the two lifting lugs 4 are arranged on the same side of the outer surface of the shell.

Preferably, the housing 3 is a hollow cylinder open at both ends.

Preferably, the filter cartridge 10 is screwed to the support plate 8.

Preferably, the fillet weld of the support plate 8 and the right opening of the shell 3 is 8mm in size.

When the hydrogen filter works actually, the inlet flange 1 in the hydrogen filter disclosed by the utility model is connected with a hydrogen pipeline or used equipment, and the outlet flange 7 is connected with the hydrogen pipeline or used equipment; hydrogen enters the filter from the hydrogen inlet a, is discharged from the filter element port after being filtered by the filter element 10, and enters a hydrogen pipeline or used equipment through the hydrogen outlet b.
