Abstract
The utility model discloses a refined sulphuric acid burner gas precision filter, including import ring flange, filtration barrel, filter element, barrel end cover and export ring flange, the middle part longitudinal installation has the fender that separates in the cartridge filter, separates the fender and will filter the inside filter chamber that divide into two the same of barrel, is equipped with filter element in the filter chamber, and filter element includes frame and the filter cloth of parcel on the frame, and the middle part connecting rod of frame is the arc. The utility model discloses can make sulphuric acid burner gas get into the internal reposition of redundant personnel of cartridge filter, and then separately filter, improve filterable efficiency to guarantee the production quality of refined acid.
Description
Technical Field
The utility model belongs to the field of sulfuric acid preparation, concretely relates to refined sulfuric acid burner gas precision filter.
Background
In the preparation of refined sulfuric acid, the SO of the sulfuric acid production system must be used3Furnace gas, SO entrained by sulfuric acid3The furnace gas often carries impurities to enter a refined acid absorption process, the quality of the refined sulfuric acid is affected, particularly the production quality of the refined acid is directly affected, and therefore a filter is needed to remove the impurities, and the production quality of the refined acid is guaranteed.
SUMMERY OF THE UTILITY MODEL
To the deficiency that prior art exists, the utility model provides a refined sulfuric acid burner gas precision filter can solve the problem among the above-mentioned background art.
The utility model discloses a realize through following technical scheme: the utility model provides a refined sulphuric acid burner gas precision filter, includes import ring flange, filters barrel, filter element, barrel end cover and export ring flange, the middle part is vertically installed at the internal middle part of cartridge filter and is separated the plate washer, it will to separate the plate washer filter the barrel is inside to be divided into two the same filter chambers, be equipped with in the filter chamber filter element, filter element includes frame and the filter cloth of parcel on the frame, the middle part connecting rod of frame is the arc.
The frame and the filter cloth are both made of polytetrafluoroethylene.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses a vertically install the design that separates the plate washer at the middle part in the cartridge filter, will filter the inside filter chamber that divide into two the same of barrel, be equipped with filter unit in every filter chamber for sulphuric acid burner gas gets into the reposition of redundant personnel in the cartridge filter, and then separately filters, has improved filterable efficiency, thereby guarantees the production quality of refined acid.
2. The utility model discloses the middle part connecting rod of frame is the arc, and then makes the area increase of parcel filter cloth on the frame, has improved filterable area, and then has improved filterable efficiency to guarantee the production quality of refined acid.
Drawings
FIG. 1 is a schematic sectional view of the present invention;
fig. 2 is a schematic view of the structure at a-a in fig. 1.
In the drawings: 1. an inlet flange plate; 2. a filter cylinder; 3. a filter member; 31. a frame; 4. a cylinder end cover; 5. an outlet flange; 6. a baffle plate; 7. a filter chamber.
Detailed Description
The precision filter for refined sulfuric acid furnace gas as shown in figures 1 to 2 in the attached drawings of the specification comprises an inlet flange 1, a filtering cylinder 2, a filtering part 3, a cylinder end cover 4 and an outlet flange 5, wherein a baffle 6 is longitudinally arranged in the middle of the inside of the filtering cylinder 2, the baffle 6 divides the inside of the filtering cylinder 2 into two identical filtering cavities 7, the filtering part 3 is arranged in each filtering cavity 7, the filtering part 3 comprises a frame 31 and filtering cloth wrapped on the frame 31, and a connecting rod in the middle of the frame 31 is arc-shaped.
The frame 31 and the filter cloth are made of polytetrafluoroethylene.
The working process of the example is as follows:
furnace gas in the refined acid enters the filtering component 3 through the inlet flange plate 1 and is filtered through polytetrafluoroethylene filter cloth on the filtering component 3, impurity particles are remained in the two filtering cavities 7 in the filtering cylinder 2, and pure furnace gas is discharged from the outlet flange plate 5.
Because the lower extreme of filtering barrel 2 is installed barrel end cover 4, we just can be through the dismantlement to filter element 3 and barrel end cover 4, clear up the impurity of two filter chambers 7 in filtering barrel 2.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
