Abstract
The utility model relates to a middle-low temp. micro-porous duster. Filter medium is arranged between dust gas and clean air inside a dusting chamber, and the windward side of the filter medium is provided with an ash bucket and a hammer type rocker ash removing device. Due to the adoption of the filter medium made of micro-porous materials, the utility model has high dusting effect (generally can reach more than 97%), no secondary pollution, small resistance loss and long service life, being suitable for occasions with smoke exhausting temperature that is less than 400DEG C. The utility model also has simple structure, low manufacturing cost, low running cost, normalization and seriation and has important popularization and application value in the field of an industrial boiler and fields similar to the field of the industrial boiler.
Description
The utility model relates to the auxiliary equipment of the cleaning or the processing of combustion products or combustion residue, specifically a kind of deduster.
Middle low temperature ash-laden gas is one of main root of atmosphere pollution, has more than 100,000 as the existing Industrial Boiler of China, and per hour the dusty gas of Pai Chuing is about 10 billion cubic meters, although generally adopt various cleaners, dust removing effects is not very good.As the cyclonic separation dedusting, efficiency of dust collection is low, and generally only about 70%, and resistance is big, is approximately 80mmH
2O; Bag-type dusting, resistance is bigger, and fragile; The foam dedusting not only can bring secondary pollution, and can corrode back-end ductwork etc.Therefore, the dust removal problem of industrial smoke evacuation is the important topic that environmental administration waits to solve always.
The purpose of this utility model is: a kind of deduster that adopts the metal micro-holes material as filter medium is provided, realizes gas solid separation, reach the dedusting purpose.
Below in conjunction with accompanying drawing, the description by to embodiment provides the technical solution of the utility model.
Accompanying drawing: structural representation of the present utility model.
As shown in drawings, between dusty gas in dirt pocket 4 and the peace and quiet air, the filter medium 2 that adopts poromerics is set, the windward side lower end of filter medium 2 is provided with ash bucket 7, after dusty gas entered dirt pocket 4 by a, behind the medium 2, peace and quiet air was led away by b after filtration; Dust is trapped within filter medium 2 windward sides, drops in the ash bucket 7.Windward side at filter medium 2 is provided with hammer fork ash handling equipment 1, and bump filter medium 2 is in case the micropore obstruction; The dirt pocket side is provided with the preceding cleaning eye 5 and the back cleaning eye 3 of filter medium 2, and ash bucket 7 is provided with visor 6, can observe the dust stratification amount in the ash bucket.Microporous medium 2 can be the single-layer metal silk screen, the multiple layer metal web plate, and powder metallurgy plate etc., micropore size is generally about 0.5～20 μ m.
According to technological requirement, economizer, air that deduster of the present utility model can be arranged on heat transmission equipments such as boiler give before the hot device, also can be contained in thereafter.
The utility model is compared with background technology, and the useful effect that has is:
1. adopt the filter medium of microvoid material, the dust removing effects height generally can reach more than 97%, does not have secondary pollution;
2. drag losses is little, generally only is 10～30mmH
2O
3
3。Long service life was generally 5～10 years;
4. be applicable to that exhaust gas temperature is not more than 400 ℃ occasion.
In addition, characteristics such as the utility model also has simple in structure, and cost is low, and running expense is low can be standardized and seriation, therefore, have great application value in Industrial Boiler and near field.
Claims (3)
