Abstract
The invention relates to an XMC-type crystal cotton skeletonless pulse dust removal device. Filter materials in the dust removal device adopt novel materials, namely crystal cotton, and the highest application temperature can reach more than 1500 DEG C; the service life is high and the longest service life can be 10 years, and the crystal cotton has strong acid resistance, alkali resistance and corrosion resistance; and the filtration efficiency reaches more than 99.9 percent, and the emission concentration is less than 1 micrometer. The operating principle of the device is as follows: dusty high-temperature air enters into a tank body 9 of a dust remover from a dusty air inlet 12, passes through a closed ended crystal cotton filter bag 8 and a bottomless crystal cotton filter bag 5 from the outer surface to the inner surface, arrives at a clean area on the upper part of the dust remover, and is emptied. When dust particles become thicker, a blowing system is started through PLC, and the dust particles are cleaned off by utilization of contra injection of compressed air; the dust particles which are absorbed on the outer surface of the crystal cotton filter bag can be cleaned off by air flow which is instantly blown in the reverse direction and the air pressure brought by the air flow; and after the dust particles are dropped off, the dust particles are fallen into a dust cabin and exhausted out of the dust remover from a dust falling opening 17.
Description
Technical field
The present invention relates to a kind of crystal cotton frameless pulse precipitation apparatus, relate in particular to a kind of dust arrester that is fit to various high temperature, corrosive gas.
Technical background
Along with the rapid growth of national economy, brought going from bad to worse of earth environment.Along with country continues to increase the dynamics of environmental requirement, the dedusting discharge index is decided to be :≤50mg/m
3Present domestic dedusting industry adopts electric precipitation, bag-type dust mostly, satisfies the discharge standard of current national requirements for environmental protection only.Moreover existing filter bag is owing to be subjected to the restriction of temperature, and must add supporting cooling installation in system, and the while does not also have effective anti-corrosion measure for corrosive gas.So, need increase very big expense aspect the energy and the material, and the replacement cycle of environmental protection facility is very short, this is not inconsistent with the state basic policy of saving energy and reduce the cost at all.Traditional sack cleaner adopts cooling, preserving method, promptly in system, increase equipment such as aerial cooler, though this technology can reach the purpose of cooling, but the temperature of high-temperature flue gas is unsettled, so be difficult to guarantee operation steady in a long-term, the life-span of equipment also has a greatly reduced quality, and the maintenance of equipment amount is very big.In this case, a kind of crystal cotton frameless pulse precipitation apparatus is quietly given birth to. and this device is low with its operating cost, efficient is high, stable, applied widely, long service life, and has obtained affirming of users and relevant department, expert.
Crystal cotton frameless pulse precipitation apparatus has the technical advantage that is different from other dedusters, its filter efficiency is apparently higher than electric cleaner, sack cleaner and wet scrubber, fund input is lacked than other deduster, and operating cost is well below the deduster of other types.Be a kind of novel dust removing equipment that is worthy to be popularized.
Summary of the invention
The invention provides a kind of crystal cotton frameless pulse precipitation apparatus, is a kind of applied widely, long service life, operating cost is low, efficient is high novel high-efficiency environment friendly equipment.
What the filtration filtrate in the pulse dust removal device of the present invention adopted is new material---brilliant cotton, Applicable temperature reaches as high as more than 1500 ℃, thereby just saves the expense of this link of cooling; And long service life, the longlyest move 10 years, reduced the stopping production that causes because of the filtrate problem in service, cause unnecessary economic loss, significantly reduced the maintenance link, saved human and material resources; Corrosivity also is the importance that cleaner need be considered, and this filtrate is to adopt non-ceramic fibre material to make, and has extremely strong acid-alkali-corrosive-resisting performance; This kind filtrate can make the filter efficiency of deduster reach more than 99.9% simultaneously, and concentration of emission is below 1 μ m.The most important thing is that this deduster does not need the support of metallic framework, has saved steel.This device adopts the PLC automatic control system, and is simple and compact for structure, simple to operately guarantees stable and reliable operation, and can be connected with the national environmental protection on-line monitoring system is supporting, realizes remote on-line monitoring.
Crystal cotton frameless pulse precipitation apparatus of the present invention is widely used in that high-temperature flue gas purification that heat power plant boiler, cement plant, mine, metallurgy, chemical industry, pharmacy, fragmentation, the hot stove of food and various ore deposit, blast furnace etc. are produced is handled and the recovery of material.Especially to the heavy metal in the flue gas of refuse burning, especially Hg, bioxin (PCDDS), furans pernicious gases such as (PCDFs) have good catharsis, can also effectively purify pernicious gases such as cyanide, arsenide, ammonia, carbon monoxide, benzene, chlorine, formaldehyde.
Crystal cotton frameless pulse precipitation apparatus of the present invention has following advantage:
Floor space is little, in light weight, small investment, operating cost is low, Applicable temperature is wide, corrosion-resistant, efficient is high.The whole system energy consumption is little, maintenance capacity is little, operating cost is low, efficient is high, and adopts steel less, and system's operation is simple and reliable.
