Two c-type fixed mounts are arranged with the housing of the air inlet, described two c-type fixed mount mutual cooperation rings are located at housing week
To on the air inlet of setting；And c-type fixed mount is provided with thick effect filter screen.
Screen pack, plasmasphere and the ultraviolet-sterilization layer of the present invention uses preform structure, by being detachably connected
Mode is installed in housing, is easy to the charge and discharge operations to purifier, when screen pack, plasmasphere or ultraviolet-sterilization layer are any
Layer damage after, only need to change corresponding to purifying layer, beneficial to reduce change and maintenance cost；In addition, go out in air inlet, first
At air port and the second air outlet, filter screen is provided with by clamshell and c-type fixed mount, clamshell and c-type fixed mount provided with filter screen are same
Sample is preform structure, is arranged on by detachable connection on housing；Clamshell is mainly used in installing efficient filter, will be efficient
Filter screen, which is fixed on clamshell, is made prefabricated component, then clamshell is integrally located on the first air outlet and the second air outlet again, just
In charge and discharge operations；It is mainly used in addition, installing efficient filter on the first air outlet and the second air outlet to through being purified in housing
Gas carry out last essence filtering, ensure and discharge gaseous mass；C-type fixed mount is mainly used in installing thick effect filter screen, will slightly imitate
Filter screen is fixed on c-type fixed mount, and then two c-type fixed mounts are fastened in the housing sidewall of air inlet again, are easy to fill
Unload operation；Thick effect filter screen is mainly used in carrying out preliminary filtration treatment to the waste gas of adsorptive purifier, removes granular powder trifle in the world
Thing.Finally, air intake choma is set can be divided into two-way and purified respectively with housing surrounding, the gas into housing：Air inlet is to
Purification channel, the air inlet to the purification channel of the second air outlet of one air outlet, effectively improve ventilation, realize high-efficient purification.
Preferably, installation is circumferentially offered at the first air outlet of the housing and the port edge of the second air outlet
Groove, the clamshell open end edge are embedded in the mounting groove, and the edge of clamshell is provided with magnetic stripe absorption and is fixed on mounting groove
It is interior.
Carried out at the first air outlet and the second air outlet of clamshell and housing by embedded mounting groove and magnet adsorption effect
Fixation is detachably connected, it is simple in construction, it is easy to operate, and have good sealing function.
Preferably, convex is provided with installing plate in the openend side wall of the c-type fixed mount, is offered on the installing plate
Through hole；Described two c-type fixed mounts are arranged the air inlet of sub- housing, pass through two installing plates being in contact of screw bolt passes
On through hole two c-type fixed mounts are pressed abd fixed on air inlet.
Set installing plate, through hole and bolt to be mainly used in c-type fixed mount being pressed abd fixed on the air inlet of housing, both protected

Enter in housing, and hermatic door is provided with installing port.
Plasmasphere, ultraviolet-sterilization layer and screen pack are detachably pacified in a manner of being coordinated and being slided by chute and slide rail
It is simple in construction loaded in housing, it is easy to operate, substantially increase the efficiency of loading and unloading.
Preferably, the screen pack uses activated carbon adsorption layer.
After gas enters housing by air inlet, it is divided into the two-way branch flow vertical with airintake direction, especially flows up
Gas in the particulate matter that does not remove because inertia and self gravitation effect can deposit downwards, by air inlet and the second air-out
Set sieve plate to be mainly used in removing this partial particulate thing impurity on passage between mouthful, and there is pole using activated carbon adsorption layer
High adsorption surface area and absorption property, prevent particulate contaminant from falling into plasmasphere both ultraviolet-sterilization layers.
Preferably, by the plasmasphere on the passage of air inlet to the second air outlet and ultraviolet-sterilization layer in the housing
Thickness is respectively by the thickness of corresponding plasmasphere and ultraviolet-sterilization layer on the passage of air inlet to the first air outlet in housing
Half.
Because the density of most waste gas is less than the density of air, it can flow up more, if entering the gas of housing by air inlet
Body is evolved by the passage between air inlet and the first air outlet mostly, then can reduce purification efficiency；The present invention is by changing two
Purification half storey thickness in passage, the resistance in air inlet to the second air outlet passage is reduced, ensure the gas that air inlet enters
Two passages are uniformly flowed to, improve purification efficiency.
Preferably, the clarifier also includes support, and the housing bottom side wall is fixed on support.
Support is set mainly to be easy to set clamshell cover with the second air outlet on housing, while can will also be installed on second
Clamshell on air outlet is strengthened being fixed on support by bolt.
The present invention compared with prior art, has the following advantages and advantages：
