Abstract
The utility model discloses an entrainment separator, belonging to a purification device in the metal smelting field and overcoming the defects in the prior art that plenty of dust and entrainment containing heavy metals are mixed in metallurgical off-gas scrubbed with dust scrubbers and environmental pollution and resource waste are caused by direct emission of the metallurgical off-gas. The entrainment separator mainly comprises a shell, wherein an entrainment inlet is formed in the bottom of the shell; an entrainment outlet is formed in the top of the shell; the upper space of the shell is larger than the lower space; two filter devices are arranged in the shell and comprise a filter screen A and a filter screen B; the filter screen A is installed above the filter screen B; the filtration pores of the filter screen A are smaller than the filtration pores of the filter screen B. The three-stage entrainment separator is mainly used for purifying the scrubbed metallurgical off-gas.
Description
Technical field
The utility model belongs to a kind of purifier in metal smelt field, specifically, relates in particular to a kind of mist catcher.
Background technology
In metal smelt process, tend to produce the flue gas during smelting of large amount of complex component, these flue gas during smeltings are directly discharged into and in natural environment, are easy to cause environmental pollution, in order to reduce the pollution of flue gas during smelting to air, people often adopt dust washing device to wash flue gas during smelting, the mist that is mixed with a large amount of dust in flue gas during smelting after washing and contains heavy metal, directly discharge will pollute the waste of environment and resource.
Summary of the invention
In order to solve the mist that is mixed with a large amount of dust and contains heavy metal in the flue gas during smelting after the washing of available technology adopting dust washing device, directly discharge will pollute the defect of environment and the wasting of resources, and the utility model provides a kind of mist catcher.
The utility model is achieved through the following technical solutions:
A kind of mist catcher, comprise housing, housing bottom is provided with mist entrance, case top is provided with mist outlet, housing upper space is greater than lower space, is provided with two groups of filters in housing, and described filter comprises screen pack first and screen pack second, screen pack first is arranged on the top of screen pack second, and the filter opening of screen pack first is less than the filter opening of screen pack second.
Compared with prior art, the beneficial effects of the utility model are:
Flue gas during smelting after washing is carried out to classified filtering, screen pack third by gross porosity falls oarse-grained dust and foamed filter, tiny foam and dust filter by the screen pack second of pore, housing upper space increases, and flue gas during smelting pressure decreased, utilizes two groups of filtration groups, by the screen pack second of gross porosity and the screen pack third of pore, filter respectively mist, in mist, heavy metal is through filtering layer by layer, discharges after reaching discharge standard, prevents mist contaminated environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mist entrance in the drawings, 1; 2, screen pack second; 3, screen pack first; 4, housing; 5, mist outlet.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of mist catcher, comprise housing 4, housing 4 bottoms are provided with mist entrance 1, housing 4 tops are provided with mist outlet 5, housing 4 upper spaces are greater than lower space, are provided with two groups of filters in housing 4, and described filter comprises screen pack first 3 and screen pack second 2, screen pack first 3 is arranged on the top of screen pack second 2, and the filter opening of screen pack first 3 is less than the filter opening of screen pack second 2.
The utility model in use, is used in conjunction with the wash mill of flue gas during smelting, and mist entrance 1 is connected with the gas vent of wash mill; During work, flue gas during smelting after washing enters in housing 4 by mist entrance 1, after the screen pack second 2 in two groups of filtration groups, screen pack first 3 are filtered, most dust and heavy metal mist are blocked in filtration group successively, and the flue gas during smelting after filtration is discharged finally by mist outlet 3.
