Abstract
The invention provides an explosion-proof filter for high-temperature flue gas. The explosion-proof filter comprises a cylinder shell, a fireproof material layer is arranged on the inner wall of the shell in a lined mode, the bottom of the shell is provided with a cone hopper ash outlet, the top end of the shell is provided with an openable cover, the side wall close to the top end of the shell is provided with a flue gas outlet, a high-temperature flue gas outlet is formed in the side wall above a cone hopper of the shell, a fixed plate is arranged in the shell and divides the shell into a top clean area and a lower flue dust area, tubular filter elements are arranged below the fixed plate, a blowback system is arranged on the upper portion of the fixed plate, and the blowback system comprises a blowback pipeline, spray nozzles which are arranged on the blowback pipeline and are opposite to the tubular filter elements, a pulse system which is connected with the blowback pipeline and arranged outside the shell and a distributor connected with the pulse system. The occupied area is small, the capturing effect is good, the filtering accuracy is high, dust particles of which the diameters are smaller than 1 micrometer can be filtered, the filtering efficiency reaches 99% or above, clean gas enters subsequent process equipment, and the emission standard is met.
Description
Technical field
The present invention relates to the high-temperature filter in metallurgical system, chemical system, power system, flue gas and dust-laden filter plant.
Background technology
The high-temperature dust contained in incineration flue gas, can make follow-up equipment pipeline dust stratification, and life-time service can cause systematic pipeline to block, and does not reaches discharging standards.
Summary of the invention
The technology of the present invention overcomes above-mentioned deficiency just, it is provided that a kind of seizure dust in high temperature normality, has superpower acid-proof alkaline and can be suitable in the flue gas environment of high temperature 350-1600 DEG C the high-temperature flue gas explosion-proof filter intercepting seizure dust.
For being to realize the object of the invention, provide techniques below scheme: a kind of high-temperature flue gas explosion-proof filter, including cylinder shell, inner walls is lined with refractory masses, housing bottom is cone bucket ash hole, housing tip is provided with openable lid, it is provided with exhanst gas outlet on the sidewall of housing nearly top, above housing cone bucket, side-walls is provided with high-temperature flue gas import, fixed plate is set in it is characterized in that housing and divides housing 135 into the clean area at top and the flue dust district of bottom, tubular type filter element it is provided with below fixed plate, fixed plate is provided above blowback system, blowback system includes blowback pipeline, it is arranged at nozzle relative with tubular type filter element on blowback pipeline, the pulse system being arranged at outside housing that is connected with blowback pipeline and be connected distributor with pulse system.
As preferably, housing cone bucket is provided with manhole.
As preferably, tubular type filter element is high temperature-resistant acid-resistant base material.
The method have the benefit that the present invention is a kind of round volume, it is without dead angle dust stratification, and to there being combustible dust at high temperature will not produce blast, tubular filter has a superpower acid-proof alkaline, high temperature resistant reaches 1600 DEG C；Do not burn, non-sticky dirt, and the resistance to temperature of high-temperature tubular filter and acid and alkali-resistance compare；Considerably beyond former old-fashioned electric cleaner, sack cleaner, dry collector.Floor space is little, it is effective to trap, filtering accuracy is high, can be with the filter diameter grit less than 1 micron, and filter efficiency reaches more than 99%, makes the gas of cleaning enter subsequent process equipment, reaches discharge standard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
nullEmbodiment 1: a kind of high-temperature flue gas explosion-proof filter，Including cylinder shell 1，Housing 1 inwall is lined with refractory masses 2，For cone bucket bottom housing 1，Cone bucket end is ash hole 1.1，Housing 1 top is provided with openable lid 1.2，It is provided with exhanst gas outlet 1.3 on the sidewall of housing 1 nearly top，Above housing 1 cone bucket, side-walls is provided with high-temperature flue gas import 1.4，Fixed plate 3 is set in housing 1 housing 1 is divided into the clean area 4 at top and the flue dust district 5 of bottom，Tubular type filter element 6 it is provided with below fixed plate 3，Fixed plate 3 is provided above blowback system 7，Blowback system 7 includes blowback pipeline 7.1、It is arranged at nozzle 7.2 relative with tubular type filter element 6 on blowback pipeline 7.1、The pulse system 7.3 being arranged at outside housing 1 that is connected with blowback pipeline 7.1 and be connected distributor 7.4 with pulse system 7.3.Housing 1 is bored bucket and is provided with manhole 8.Tubular type filter element 6 is high temperature-resistant acid-resistant base material.
The tubular type filter element of high-temperature flue gas filter is fixed in housing, and high-temperature tubular filter element is fixed in fixed plate, and fixed plate plays the buffer action to dust-containing area and clean area.Dust-laden high-temperature smoke gas enter dust-containing area and by under rear portion air-introduced machine or flue gas differential pressure action, by outer surface inner surface by filter element intercept dust, dust gear at tubular type filtering element (cartridge) outer surface, the gas making cleaning enters tubular filter in-core, is discharged into the clean area on filter top immediately.High-temperature tubular filter element is the most long-pending more thick along with outer surface dust dirt cake, and the inside and outside differential pressure of filter element is increasing；When pressure drop reaches to design pressure drop, high-temperature filter starts blowback system, utilizes compressed air contra-injection, is disposed by surface dirt cake, instantaneous back draught and the air pressure brought thereof can be disposed and adsorb the dirt cake at filter element outer surface, and dirt cake i.e. falls into dust arrester after departing from.After removing dirt cake, filtration system can start new de-dusting cycle.
