Description
Technical field
The utility model relates to gas purification technique fields, and in particular to the equipment of a kind of pair of high temperature gas cleaning dedusting.
Background technique
Dust refers to that the aerial solia particle that suspends, partial size are generally less than 75 μm, can be suspended in for a long time big
It is to lead to one of main pollution sources of air pollution in gas.The main source of dust has industry to form dust and oneself in atmosphere
So form dust.And industry is formed in dust often containing heavy metals such as a large amount of cadmium, manganese, chromium, it is more tight to the harm of human body
Weight.Research has shown that the mankind be chronically exposed to industry formed in the excessively high gas of Dust Capacity will lead to serious respiratory disease,
Cardiovascular disease and increase cancer probability.Therefore reducing industry formation dust, content is most important in an atmosphere.
The important sources that industry forms dust are the generations such as metallurgy, chemical industry synthesis, coal chemical industry and garbage disposal
Dusty gas, such as straw splitting gas, lignite cracking gas, garbage cracking gas or cracking waste plastics gas etc..These dusty gases
Temperature generally at 200 DEG C or more, since the temperature of this kind of gas is higher, so the requirement to cleaner is also very high.Mesh
Preceding common cleaner has electric dust-removing equipment, filter bag cleaner and cyclone dust removal equipment.Wherein, electric dust-removing equipment is to high temperature
When dusty gas dedusting, since the operating temperature of electric precipitation is generally below 200 DEG C, so this is just needed first to high-temperature dusty gas
Cooling, not only increases the cost of dedusting, and electric precipitation can also generate a certain amount of ozone during dedusting, make to atmosphere
At secondary pollution.Filter bag cleaner traps solid in dusty gas using the bag type filter elements that fiber fabric makes
Grain object；Although this kind of cleaner not will cause the secondary pollution to atmosphere, big to air resistance, efficiency of dust collection is low；Rotation
Wind dust-extraction unit be grit is separated from air-flow by means of centrifugal force by making dust-contained airflow rotate, then by weight
Power effect makes grit fall into ash bucket, although its resistance is smaller, dust of the cyclone dust collector for partial size less than 10 μm
Grain Scavenging activity is poor.
In order to make up the defect of above-mentioned cleaner, the cleaner more efficiently to high-temperature dusty gas is provided, in
State patent document CN10653750A discloses a kind of gas dust-removing device, dust pelletizing system and dust removal method with agitation component,
The dust-extraction unit includes the shell with air inlet and air outlet, media units and mixing component disposed in the housing,
It is provided with electrode on the side wall of the shell, so that media units and electrode is collided by the stirring of agitation portion and generates electrostatic, lead to
It crosses electrostatic the dust in gas is adsorbed on media units, achieve the effect that dedusting.Above-mentioned cleaner passes through electricity
Field action realizes the effect to the lesser granular absorption of partial size, but it must have mixing component, and mixing component is to high temperature
Tolerance it is limited, and when in dust-extraction unit when Dust Capacity reaches it is a certain amount of when, having the case where a certain amount of electrostatic
Under easily explode.
