Clarifier with cleaning function
Technical field
The present invention relates to a kind of air-flow purifier.
Background technology
Clarifier is as air cleaning unit, applied more and more, wherein high-pressure electrostatic clarifier; Comparatively general in the industry, its structure comprises housing and is located at the battery lead plate in the housing, utilizes positive-negative electrode plate to produce high voltage electric field and comes udst separation; But the cleaning of high-pressure electrostatic clarifier need disassemble usually and could accomplish at present, has so not only delayed normal purification work, dismantles and assemble simultaneously comparatively trouble again; Need great amount of manpower, long-term so operation is unrealistic, needs to improve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenience for washing to have the heat exchanger of cleaning function efficiently to the above-mentioned state of the art.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of clarifier with cleaning function is characterized in that comprising
The clarifier body comprises housing and is located at the battery lead plate in the housing that housing bottom has waste liquid outlet, and case top has the cleansing medium import;
Drip tube or sparge pipe, liquid feeding end are provided with cleansing medium valve and cleaning agent valve, and outlet end is communicated with aforesaid cleansing medium import; And
Oily-water seperating equipment has waste liquid import, waste oil outlet and wastewater outlet, and aforesaid waste liquid import is connected with the waste liquid outlet of clarifier body.
As preferably, described cleansing medium valve and cleaning agent valve are magnetic valve.Can certainly adopt mechanical hand-operated valve.
For improving cleaning performance, stop the dirt dead angle, described battery lead plate vertically is arranged in the housing, and the top of said housing has the shower of horizontally set, and this shower injection direction is over against battery lead plate.
Further, multilayer is independent of each other from top to bottom is arranged in the housing for described battery lead plate, has dividing plate between every layer of battery lead plate, and accordingly, the top of said housing has the cleansing medium import that cleansing medium is incorporated into every layer of battery lead plate.Further, described every layer of battery lead plate upper end is equipped with shower, and this shower injection direction is over against the battery lead plate of every layer of correspondence.
Compared with prior art, the invention has the advantages that: need not dismounting and just can accomplish cleaning, whole cleaning is convenient and swift, and scavenging period is shorter, does not influence normal heat exchange work basically.Overall structure is simple, and cooperation can be removed the cleaning agent of greasy dirt, and cleaning performance is comparatively desirable.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1; Clarifier 5 in the present embodiment is applied on the forming machine baking oven 100 as the secondary purification of the degree of depth, and the hot gas in the flue gas leading 7 passes through primary purifying device 4, heat exchanger 101, clarifier 5 successively; Discharge from delivery pipe 6 at last; The waste gas that produces in the cloth type-approval process is like this discharged after through heat exchange, most of heat recovery and utilization, and energy consumption reduces.
As shown in Figure 2, clarifier 5 comprises clarifier body 10, sparge pipe 3 and oily-water seperating equipment 9.
Like Fig. 3, Fig. 4 and shown in Figure 5, the clarifier body 10 in the present embodiment comprises housing 1a and is located at the battery lead plate 2a in the housing 1a, and housing 1a bottom has waste liquid outlet 4a, and housing 1a top has cleansing medium import 3a.Two layers of independent of each other being arranged in the housing 1a and vertically were provided with about battery lead plate 2a divided, and had dividing plate (nothing shows among the figure) between every layer of battery lead plate.In conjunction with Fig. 6 and shown in Figure 7, every layer of battery lead plate 2a upper end is equipped with shower 5a, and this shower 5a injection direction is over against the battery lead plate 2a of every layer of correspondence.The top of housing has two cleansing medium import 3a, and one of them introduces the upper strata with cleansing medium, and another flow into lower floor with cleansing medium.The sewage that the upper electrode plate cleans the back generation passes through the waste liquid outlet 4a that built-in conduit (nothing shows among the figure) flow into the bottom.The conduit here is near the housing disposed inboard.
In conjunction with shown in Figure 2; Sparge pipe 3 liquid feeding ends are provided with cleansing medium valve 1 and cleaning agent valve 2; Outlet end is communicated with cleansing medium import 3a; Oily-water seperating equipment 9 has waste liquid import, waste oil outlet 91 and wastewater outlet 92, and the waste liquid import is connected through header 8 with the waste liquid outlet 4a of heat exchanger body 10.Oily-water seperating equipment 9 can adopt settling tank, scraper-type hand trip device or floating-oil collector etc.
In conjunction with shown in Figure 8, for ease of control, the cleansing medium valve 1 in the present embodiment is magnetic valve with cleaning agent valve 2.Cleansing medium valve 1 can be realized control through controller with cleaning agent valve 2, and time set, scavenging period and cleaning agent adding proportion etc. can manual adjustments controls.The sparge pipe 3 here also can substitute with drip tube.Scavenging period generally was controlled in a few minutes, and is shorter, do not influence normal heat exchange work basically.Medium can adopt steam or water during cleaning.
During cleaning, close clarifier body 10, start cleaning procedure, clean the sewage that finishes and dispose through oil water separator 9.Clarifier need not dismounting, and is convenient and swift.
