Abstract
The utility model provides a high temp. gas dust remover. The utility model is characterized in that the high temp. gas dust remover uses a ceramic tube to filter, solid particles passing through the multi-hole wall of the ceramic tube are intercepted by the multi-hole wall to fall into an ash hopper, after clean gas is mixed in the inner cavity of the ceramic tube, the clean gas reaches a pressure balancing chamber through an outlet, gas going out the balancing chamber goes to a subsequent working section. The utility model is suitable for eliminating the high temp. outlet coil gas of fluidized bed gasifying furnaces, the high temp. outlet combustion gas of fluidized bed boilers or solid particles in the high temp. outlet gas of smelting furnaces.
Description
The utility model relates to a kind of gas cleaning at high temperature device, particularly earthenware deduster.
At present, China's dedusting mainly adopts cyclone dust collectors, sack cleaner and electrostatic precipitator, the subject matter that they exist is: cyclone dust collectors efficiency of dust collection low (＜85%), sack cleaner and electrostatic precipitator can not high temperature resistant (＜250 ℃), three's common drawback is not withstand voltage, and general occasion is normal pressure equipment.
This practical purpose provides a kind of high temperature, high pressure, high efficiency dedusting device, solves the thermal release problem of solid particle in the gas.
The purpose of this utility model can reach by following measure, 1. earthenware fixed disk upper and lower end face outer rim is respectively sealing surface and the connecting screw hole that is complementary with pressure equalizing chamber bottom metal flange sealing surface and pressure vessel top metal flange sealing surface, the center is the earthenware installing hole of band seal boss, is the housing pin hole around the installing hole; 2. earthenware top is flange, and the bottom is a garden arcuation end socket.Earthenware stretches in the pressure vessel through earthenware fixed disk center mounting hole during assembling, and flange relies on the soft seal circle be enclosed within the earthenware neck to coincide in center mounting hole on the seal boss; 3. the sealing gland lower surface is the sealing convex surface that is complementary with the earthenware flange, and outer rim is the screw connecting hole that is complementary with earthenware fixed disk housing pin hole, and the center is that clean gas portals.Assembling back sealing gland is locked in the earthenware outer end by soft seal pad and housing pin.4. dust remover roof is provided with high-voltage pulse blowback nitrogen system, and the nitrogen nozzle portals through pressure balance chamber interior, sealing gland gas and enters the earthenware inner chamber.
The utility model compared with prior art has following advantage:
(1) deduster pressurized chamber is high pressure resistant stainless steel thick wall shell, high temperature resistant silicon carbide ceramics screen pipe is installed in high-pressure chamber inside by special device, this does not bear gas-static earthenware in dust removal process, so the utility model can use under high-temperature high-pressure state.Whole device design pressure 2.0MPa, 800 ℃ of design temperatures are handled tolerance 50-100NM
3/ h.(2) ceramic filter tube adopts common process to fire, the prosperity of filter membrane micropore, and diameter is 5-30 μ, so deduster efficiency of dust collection height generally can reach more than 99.9%, (3) are simple in structure, and are easy to maintenance.
Accompanying drawing is that this is suitable for novel structural representation.
Below in conjunction with accompanying drawing facility example of the present utility model is further described:
As shown in the figure: the outer silk of high alumina heating tube 1, pressure vessel 2, earthenware 3, earthenware fixed disk 4, sealing gland 5, pressure equalizing chamber 6, deduster metal flange 7, metal shell 8, ash bucket 9, temperature controller 10, high pressure nitrogen 11, dusty gas 12, clean gas 13.Ceramic flange is connected with fixed disk 4 by two-sided soft seal; Sealing gland 5 is locked in the outer end of ceramic flange by hold-down bolt; The existence of pressure equalizing chamber 6, the pressure of balance earthenware surfaces externally and internally on the one hand makes end of gas seal in the sealing that is transferred between metal flange 7 and the earthenware fixed disk 4 on the other hand and goes.Earthenware 3 adopts carborundum to make base stock, and porous wall two-layerly is made of inside and outside, and internal layer is passive rigid backbone, and skin is the ceramic filter membrane of micropore prosperity.
The high temperature dust gas 12 that comes from cyclone dust collectors during operation imports pressure vessel 2 through the deduster bottom, then, pass earthenware porous wall 3, solid particle falls into ash bucket 9 through the porous wall interception, clean gas is after the earthenware inner chamber converges, arrive pressure equalizing chamber 6 through outlet, the gas 13 that goes out the balance cylinder goes to follow-up workshop section.High voltage pulse nitrogen 11 blows off and is adsorbed on the ash cake of earthenware outer wall.
Claims (1)
