Continuously purifying device for circulate bed

The utility model belongs to drinking water and technical field of sewage treatment equipment.Be particularly useful for the river, the lake is the small-sized drinking water treatment in village, township, town at water source and the processing of sanitary sewage and the not too big trade effluent of viscosity that all trades and professions produce.

Along with industry constantly develops, industrial water consumption increases gradually and produces a large amount of sewage, has not only polluted environment, has also polluted the water source.Prevent that for China that water resource lacks pollution of waterhead is very important, especially utilizing river, lake to be the area, drinking water source, guarantee that drinking water quality standard is current pressing issues.The filtering technique of water is a very important technology, therefore, constantly pursues both at home and abroad and develops simple, efficient, the novel easily filter of Economics and Management.Japan works out the body-internal-circulation continuous filter in nineteen eighty-two, as shown in Figure 1.Processed former water is entered by water inlet pipe ［ 13 ］, flows into former pool ［ 1 ］, enters layer of sand ［ 3 ］ by import ［ 2 ］, suspension is removed, clean water flows into the user by entering clean water chamber ［ 8 ］ every sand net ［ 7 ］ by clear water outlet pipe ［ 9 ］, has finished filter process.Sand, water and the mud that is trapped pass through compressed air hose ［ 14 ］ in device bottom, enter into sand extraction tube ［ 10 ］, in pipe, enter silt particle separation chamber ［ 4 ］ after the vigorous stirring collision, compressed air hose in the separation chamber ［ 11 ］ is sent into compressed gas and is stirred again, mud and water are drained from discharge pipeline ［ 12 ］, and the sand of being cleaned enters the filter chamber by import ［ 2 ］, is distributed in the layer of sand surface, reach the circulation back and forth of sand, the purpose that mud constantly separates.

The extracorporal circulatory system continous way RSF type filter that Fig. 2 worked out for Japan in 1987.Processed former water is entered from filter bottom by water inlet pipe ［ 21 ］, holds back suspension by filter course ［ 22 ］, and clear water slowly rises and enters cloth sand umbrella ［ 23 ］ top and enter in the water leg ［ 24 ］, supplies with the user, finishes filter process.Sand, water and mud flow to upgrading slot ［ 25 ］, sand, water and mud are sent into the silt particle separation chamber ［ 27 ］ at top with compressed gas by riser ［ 26 ］, carrying out sand separates with mud and cleans, mud and rinse water are together discharged by sump ［ 28 ］, the clean sand that cleaned is by cloth sand umbrella and barrel gap, again fall above the filter course, add auxiliary water tube ［ 29 ］ for sand, water and mud are better flowed in carrier pipe, thereby reach the purpose of automatic washed-out sand of circulation and continuous filtration.China Jiangsu Province building environmental protection research institute copys the CF series extracorporal circulatory system continous way sand filtration water purifier that Japanese RSF series is produced, and its technical performance reaches external like product level.

In sum, use between body-internal-circulation filter course ［ 3 ］ and the clean water chamber every sand net ［ 7 ］ separately, promptly will bear the pressure of filter course sand every the sand net, prevent that again sand runs off, resistance is greatly inevitable like this, and the area of Guo Lving is again little simultaneously.And extracorporal circulatory system has solved this difficult problem.But the common problem that exists of these three kinds of products is that floor space is a unit, and filter area also is a unit, and utilizes compressed gas to carry sand continuously, and air consumption is big, and is uneconomical.

The purpose of this utility model is intended to solve above-mentioned weak point, proposes circulation fluidized bed continous way water purifier.The shutter that utilization is holded up filters, and improves the filter element area.Utilize the plunger induction system, save a large amount of compressed gas.Reduce cost.

Primary structure of the present utility model is made up of two filter beds, cavity, plunger induction system and the separation chamber that four fan louvre blades constitute.Processed water by water inlet pipe in the cavity the filter bed, processed water precipitates at this, enters two filter beds by the inboard louvre blade of two fans simultaneously, and mud is trapped at this, clear water flows into two header tanks respectively by two fan outside louvre blades, uses for the user.Be filtered mud, water and filtrate that bed is held back, send into the separation chamber by the plunger induction system of controller, pulse valve and air knife formation and separate.The separation chamber is made up of carrier pipe, discharge pipeline, upper hopper and playpipe.

The main advantage of the utility model is to utilize four fan louvre blades to form two filter beds, on 1 unit of floor space, the area of 5～6 times filter element is just arranged, when filtering velocity equates, this patent is 5～6 times the processing water yield of above-mentioned three products, but cost only is 1/4.Utilizing the plunger induction system in addition, is that one section filtrate water, one section gas, one section filtrate water, one section gas are the trifle section and rise in course of conveying, and hoisting velocity is slow, and tube wear is little, saves a large amount of compressed gas.
