Description
Technical field
The present invention relates to a kind of processing and clean rainwater for the filter of cooling tower moisturizing.
Background technology
Along with economic society is fast-developing, there is the lack of water of different reasons in the most cities of China, southern area water quality lack of water is even more serious, and the problem that water for industrial use and cities and towns water are vied each other has also appearred in some area, and shortage of water resources has become one of key factor of restriction socio-economic development.Recirculated cooling water refers to the cooling production equipment of water, refrigeration machine etc., and the temperature of water self raises, and by cooling device, water temperature is reduced, recycles.The consumption of cooling water is very huge, and for example the cooling tower rate of water make-up of some public buildings accounts for the 30%-50% of building total water amount, is all to adopt running water as moisturizing at present, has more aggravated the present situation of water scarcity.Nationwide rainfall season and air-conditioning are used season roughly the same.Rainy season, rainfall was large, especially southern area rainfall is shorter interval time, in urban hard underlying surface except the with serious pollution underlying surface Rainwater Qualities such as motor road are poor, other hard underlying surface rainfall runofves water quality after 10 minutes is more clean, and major pollutants are chemical requirement (COD), solid suspension (SS), turbidity etc.But current rare cooling tower adopts rainwater as moisturizing, be mainly that administrative staff think that device for treating rain water needs special maintenance, operation cost also can increase, and uses inconvenience, safeguards complicated.On the one hand, except initial rainfall, a large amount of hard underlying surface rainfall runoff water quality is better, has a large amount of good water sources to utilize; Administrative staff think that treatment facility complexity needs special messenger to safeguard on the other hand, cause the enthusiasm of rainwater utilization not high; How device for treating rain water being simplified, reduced operating cost, can control major pollutants again, guarantee water quality treatment amount, is the key that advances rainwater catchment system.
The existing patent application that rainfall runoff is processed mostly is simple solid-liquid separator, needs periodic maintenance, and the effects of purification quality after the device processes of automatic backwash is limited, for example:
China Patent Publication No. CN102614688A discloses a kind of rainwater runoff pollution treatment facility with self-cleaning function, this treatment facility is only the precipitate and separate to rainfall runoff, takes up an area greatlyr, and clean-up effect is limited, be mainly used in pollution more serious, the rainfall runoff precipitate and separate that silt is more.
China Patent Publication No. CN202410360U discloses a kind of dmp filter purifier, and this device adopts fibre bundle simple structure, has realized gravity backwash, but equipment filters for the processing of early-stage rainwater and need to regular labor cleaning.
The disclosed apparatus structure of China Patent Publication No. CN2249634Y, CN202410274U is simpler, but has special backwashing system, and power consumption increases controlling unit when increasing, and is unfavorable for system maintenance.
Summary of the invention
The object of the present invention is to provide a kind of processing to clean rainwater for the filter of cooling tower moisturizing, when effectively controlling major pollutants, solving existing equipment needs the problem of safeguarding specially, promotes carrying out of rainwater utilization.
To achieve these goals, the technical solution used in the present invention is:

Container of the present invention is provided with upper cover, and described upper cover and container are connected to form the space of a sealing.
Upper cover of the present invention is connected with container by hasp or screw buckle, and upper cover can facilitate the periodic inspection of equipment, and the hasp between upper cover and container or screw buckle can guarantee flexible and convenient operation.
The top of upper cover of the present invention is provided with passage, to get rid of and enter the gas in container in time.
The bottom of light filler of the present invention, the top of perforated plate are provided with supporting layer, and supporting layer has a fixed gap and realizes Quick drainage backwash.
The bottom of container of the present invention has certain gradient or is the impurity eliminating that back taper is convenient to precipitation.
The present invention also comprises PLC electrical control cubicles, and described PLC electrical control cubicles is connected with electric-controlled switch, and electric-controlled switch is by receiving the folding of the On/Off signal controlling self of intake pump.
Compared with prior art, the present invention has following remarkable result:
(1) the present invention utilizes the characteristic of light filler to realize gravity type automatic backwash, and the backwash pump that does not need conventional filtration equipment to arrange, has saved initial cost.
(2) the present invention does not need special maintenance, saves human cost, easy to use.
(3) the present invention is except container and accessory weight, and filler weight is negligible, and weight of equipment alleviates greatly, can be used in the position of load-bearing requirement, is convenient to transportation and installs.
(4) the present invention is because the characteristic loss of flood peak of light filler is little, low to the performance requirement of intake pump, reduces equipment performance requirement, reduces investment outlay equally.
