Abstract

The utility model discloses a wet type filter with serial type ball-body grid plates and belongs to the filter. By adoption of the wet type filter, the technical problems of large filtering resistance, poor dedusting effect and no self-cleaning capability and the like of the existing filter can be solved. The key points of the technical scheme are as follows: the wet type filter comprises the serial type ball-body grid plates (1), pressing bolts (2),a shell (3) and a cover plate (4), wherein the serial type ball-body grid plates (1) adopt fine metal wires (101); after perforated plastic balls (104) are connected in series, a plurality of rows of plastic balls are combined and fixed on a structural frame (103) by tensioning devices (102) to form the ball-body grid plate (1), and then the serial type ball-body grid plates with same structures are overlapped and combined, are arranged in the shell (3) in series and are used for filtering steam-water mixture containing dust. The filter with the structure generates slight vibration under the action of airflow by means of the ball bodies, cleans the deposited dust on the ball bodies automatically without adding an external power device, and is mainly applied in horizontal type dedusting systems for mines and the like with limited installation height.

Description

A kind of string row formula spheroid screen wet filter

Technical field

The utility model relates to a kind of filter, particularly a kind of string row formula spheroid screen wet filter.

Background technology

At present, the filter by ball filler as filter medium, at iron and steel, be widely used in the industries such as chemical industry, building materials.Its main application mode is on the packed bed in vertical turbulent tower, place certain thickness hollow plastic pellet 104, air-flow is passed through packed bed from the bottom of tower, rely on the power of air-flow, make baton round 104 produce irregular motion, simultaneously, in the top of filling ball spray water mist, produce moisture film at spherome surface on the one hand, the dust in gas is produced and adheres to, on the other hand the laying dust of spherome surface produced to cleaning performance.This frame mode part that comes with some shortcomings: when packing layer thickness is larger, when the pressure of gas is inadequate, the spheroid filler is difficult for forming turbulence state, and the filtration filtration resistance power of packing layer is large.When the spheroid thickness low LCL, and gas pressure is on packed bed during skewness, and spheroid easily produces again packing phenomenon, and packing layer is poor again to the adhesiving effect of the dust in gas.

Summary of the invention

It is little that the purpose of this utility model is to provide a kind of filtration resistance, good dedusting effect, the string row formula spheroid screen wet filter with automatically cleaning ability.

The utility model solves the technical scheme that its technical problem adopts: it comprises string row formula spheroid screen 1, hold-down bolt 2, housing 3, cover plate 4, many string row formula spheroid screens 1 overlay in housing 3, fixing with hold-down bolt 2, cover plate 4 is for the installation or removal screen.

String row formula spheroid screen 1 described in the utility model comprises baton round 104, and baton round 104 forms string by wire 101, and every string spheroid forms row by tensioning apparatus 102 on structural framing 103 sections.

The utility model is in housing 3, and a plurality of same structure string row formula spheroid screens 1 in tandem, fix with hold-down bolt 2.

Tensioning apparatus 102 disposed at equal distance described in the utility model are on the horizontal or vertical direction of framework, and every one metal wire 101 of spheroid in tandem, respectively have a set of tensioning apparatus 102.

The perforation of baton round 104 described in the utility model is in the sphere diameter position.Sphere diameter is φ 25-φ 30, and aperture is about 2mm.

Structural framing 103 described in the utility model is rectangle.

The beneficial effects of the utility model are: 1, filtration resistance is little, single string row's spheroid screen, the gap between spheroid is larger, dust-contained airflow was worn screen, grit with moisture film on spheroid, contact produce adhesion and condense and and flow separation; 2, under the effect of air-flow, string comes the spheroid on wire 101, can produce with air-flow the vibrations of pettiness, when the grit gathered when spherome surface reaches certain thickness, and can be automatically from breaking away from surface; Without add-on device and manpower, the laying dust on the Automatic clearance spheroid, realize the regeneration of filtering function; 3, change easy to clean, in During Process of Long-term Operation, the residual laying dust on screen is more, while affecting strainability, can open cover plate 4, takes out screen and cleans.
