Description

A kind of pressure relief filter with grate plate
Technical field
A kind of filter is the utility model is related to, specially a kind of pressure relief filter with grate plate, belonging to filter should Use technical field.
Background technology
Coal chemical technology widely uses pressure relief filter to filter the dust granules in pressure release gas, reduces the pollution of environment. Such as in gasification furnace coal adding system, lock hopper passes through the purpose of filling pressure release to realize to gasification furnace coal, in lock hopper pressure release, pressure release Contain a large amount of dust, it is necessary to be filtered to pressure release gas in gas, then discharge.
Filter element of gas filter material has Fe3Al, woven wire, ceramics etc. several.Ceramic element poor toughness, is used primarily in On fly-ash filter, for the dust in filtering technique coal gas, seldom apply in pressure relief filter.Pressure relief filter now uses Fe3Al metal agglomeration filter cores and metal fiber felt silk screen filter core, main cause are that pressure relief filter working environment is complicated, such as pressure release Speed is very fast, and filter core both ends pressure difference is big etc., and this needs filter core to have enough intensity and toughness.
The metal filtering core specification that pressure relief filter uses is essentiallyBecause pressure relief filter operating mode is complicated, filter The situation of breaking releasing often occurs in core, and after filter core fracture, fracture filter core generally enters lock hopper with blowback air-flow, then Other systems are entered back into, until it is stuck by valve or pipeline, filter core is at this moment broken by the stable operation of serious threat system.
After the fracture of pressure relief filter filter core, have substantial amounts of dust and be discharged, environment is needed by serious pollution Damage equipment is repaired as early as possible, and takes out the filter core of fracture, it is generally the case that larger breaking portion can rest on filter Tapering, less part enter lock hopper and other device interiors, want to be drawn off that substantial amounts of manpower and time need to be expended, therefore, A kind of pressure relief filter with grate plate is proposed regarding to the issue above.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of pressure relief filter with grate plate.
The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of pressure relief filter with grate plate, bag Include filter tapering and the filtering air inlet installed in filter tapering low side, the top inside the filter tapering End is provided with grate plate, and filter core fixed tube sheet is provided with the top of the grate plate, gas is provided with the filter core fixed tube sheet Body filter core;The filter core fixed tube sheet is provided with filter core gas outlet, and end socket is fixed with the outside of the filter core fixed tube sheet Fastening bolt;The top of the filter core fixed tube sheet is provided with ellipse head, and the top of the ellipse head is provided with filter outlet Mouthful.
Preferably, the gas filtration filter core is cylindrical structural.
Preferably, circumferentially array is distributed the gas filtration filter core on the filter core fixed tube sheet.
Preferably, the grate plate is grid-shaped structure, and grid is circular configuration.
Preferably, the circular port of the grate plate is less than the diameter of the gas filtration filter core.
The beneficial effects of the utility model are:The circular port of grate plate of the present utility model is less than the straight of gas filtration filter core Footpath, be advantageous to be intercepted the filter core of fracture, filter core is unlikely to failure after fracture and further expand, overall structure Compact, overall volume is small, and maintenance is convenient, and when gas filtration filter core is broken, the filter core of fracture can be intercepted and stayed by grate plate In the top of grate plate, avoid fracture filter core from entering pressure release lock hopper, jam valve and pipeline with blowback air, there is good economic effect Benefit and social benefit, are adapted to promote the use of.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram;
Fig. 2 is the utility model grate plate scheme of installation.
In figure:1st, filtering air inlet, 2, filter tapering, 3, grate plate, 4, gas filtration filter core, 5, filter core fixing pipe Plate, 6, filter core gas outlet, 7, ellipse head, 8, filter outlet mouth, 9, end socket fastening bolt.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to shown in Fig. 1-2, a kind of pressure relief filter with grate plate, including filter tapering 2 and installed in institute State the filtering air inlet 1 of the low side of filter tapering 2, the top inside the filter tapering 2 is provided with grate plate 3, described The top of grate plate 3 is provided with filter core fixed tube sheet 5, and gas filtration filter core 4 is provided with the filter core fixed tube sheet 5;It is described Filter core fixed tube sheet 5 is provided with filter core gas outlet 6, and the outside of the filter core fixed tube sheet 5 is fixed with end socket fastening bolt 9;Institute The top for stating filter core fixed tube sheet 5 is provided with ellipse head 7, and the top of ellipse head 7 is provided with filter outlet mouth 8.
As a kind of technical optimization scheme of the present utility model, the gas filtration filter core 4 is cylindrical structural.
As a kind of technical optimization scheme of the present utility model, the gas filtration filter core 4 is in the filter core fixed tube sheet 5 On circumferentially array be distributed.
As a kind of technical optimization scheme of the present utility model, the grate plate 3 is grid-shaped structure, and grid is circle Structure.
As a kind of technical optimization scheme of the present utility model, the circular port of the grate plate 3 is less than the gas filtration The diameter of filter core 4.
When in use, in pressure leak process, when lock hopper needs pressure release, pressure release gas is by filtering air inlet 1 for the utility model Into pressure relief filter, the dust in pressure release gas is intercepted by gas filtration filter core 4, and clean gas is by filter core gas outlet 6 Into the top of pressure relief filter, then discharged by filter outlet mouth 8;In blowback punching course, when lock hopper needs to rush During pressure, gases at high pressure first pass through filter outlet mouth 8, and into pressure relief filter, gases at high pressure enter filter core by filter core gas outlet 6 Inside 4, blowback is carried out to filter core 4, entered after being discharged together by filtering air inlet 1 by the dust under blowback and gases at high pressure Lock hopper, complete the punching course of lock hopper.Filter core fracture intercepts, and when gas filtration filter core 4 is broken, grate plate 3 can be by fracture Filter core intercepts the top for staying at grate plate 3, avoids fracture filter core from entering pressure release lock hopper, jam valve and pipe with blowback air Road.
