Abstract

The utility model relates to environment protection equipment. The utility model is designed and provided to solve the problems that the separating process effect of the oil and dust of the waste water discharged by the existing wet dust extraction filter is not ideal, and the occupied area of the equipment is big. The utility model is mainly composed of a vertical type box body, a sewage standing tank arranged on the top of the box body, a filtering group arranged under the tank, a water purifying tank arranged under the filtering group, and a cleaning door on the box body. The waste water is precipitated and is filtered through multiple process, more than 98% of the powder dust and the foreign matter are filtered out, the de-oiling rate can reach 80%, and the circulating using purified water can be obtain; meanwhile, the occupied are of the equipment is small, and the maintenance is convenient.

Description

Recirculated water oil dirt separation processor

The utility model relates to environment protection equipment.

At present, the wet dust removal filter of administering flue gas is more, and for the wastewater treatment that this class dust removal filter is discharged, middle-size and small-size being mostly is in line, and waste water 100% is drained, and does not have circulation or recycles very waste.Relatively large employing filtering ponds, water is reusable, but the filtering ponds floor space is big, and filtration time is also long.Also simple water tank of some middle-size and small-size employing is done the recirculated water use, greasy dirt adopts from overflowing and handles, and dust adopts sedimentation to handle, though certain effect is arranged, but because of dust needs certain hour from sedimentation, often the dust in the water tank does not also drop to the bottom and is just taken away a part by the current of water pump.Even dropped to the dust of bottom, also taken away by the current of water pump easily.The capital causes nozzle to stop up, and lowers dust removing effects.

The purpose of this utility model is to overcome above-mentioned shortcoming, designs, provides a kind of floor space little, to contained dust, greasy dirt, foreign material filtration, the fabulous recirculated water oil dirt separation processor of separating effect in the waste water.

Main structure of the present utility model is: a vertical casing is arranged, and the casing top is provided with sewage and leaves standstill the pond, and the filter screen group is equipped with in below, this pond, and filter screen group below be a water purifying tank, the filter screen group right chest portion be arranged with and clean.

The sewage that the sewage that dust removal filter is discharged is pumped to the vertical cabinet top leaves standstill the pond, overflows behind the Chi Shuiman, is waterfall shape and flows down, and runs down in the water purifying tank after filtering through the filter screen group that comprises the multiple tracks filter screen again.Oil slick is discharged from the oil scupper at casing middle part, and dust, foreign material leave standstill the slagging pipe of bottom, pond and the slagging pipe of water purifying tank bottom is discharged from sewage, and the water of water purifying tank is pumped after outlet pipe refilters after filtration and recycles.

The filter screen group comprises the multiple tracks filter screen, can adopt oblique filter screen, also available conical screen or other forms of filter screen and their combination.

For effective filtration number of times that can guarantee sewage with separate oil, dirt better, below each oblique filter screen or downside water fender is arranged.In the conical screen side water fender is arranged also.

For the ease of discharging oil slick, be provided with oil scupper on water purifying tank top, allow the horizontal overflow of oil slick discharge.

In addition, also be provided with control water polo valve on water purifying tank top, when the water purifying tank water level was lower than the ball valve control line, ball valve was that nature is opened from the outside to the additional water source of water purifying tank.

The utility model has following advantage:

1, vertical modern design is reasonable, takes up an area of few.

2, save clear water, guaranteed the no slag degree of recirculated water simultaneously.Filter effect to dust reaches 98%, and bigger particle foreign material filter effect is reached 99.9%, and the de-oiling rate reaches 80%, and as seen its filter effect is splendid.So waste water can be recycled and the difficult nozzle that stops up through handling.

3, easy to maintenance, clean easily.

Further specified below in conjunction with accompanying drawing and illustrated embodiment:

Fig. 1 is an organigram of the present utility model;

Fig. 2 looks schematic diagram for the right side of the present utility model.

See Fig. 1,2, the waste water of dust removal filter being discharged with pump is pumped to the sewage at casing of the present utility model 1 top and is left standstill pond 2, big heavier dust foreign material are in this sedimentation, overflow outside the pond after the sewage storage is full, being waterfall shape flows down successively below the oblique filter screen 5 in four roads that are separated by through length and each oblique filter screen or the water fender 7 of downside, dust major part in the sewage is hunted down, and oil slick overflows to oil scupper 9 outflows.Remaining then flows into tapered filter screen 6 set with water and filters, and the one side also has water fender 7.Water purification falls into water purifying tank 3, and remaining oil slick flows out through oil scupper 9 and drain line 13.The water of water purifying tank refilters once through the water pipe 10 that filters out of bottom, pond.The available then pump that adds is pumped to the dust removal filter repeated use.Be lower than the control line of control water polo valve 8 when the water purifying tank water level after, can be through make-up pipe 14 to water purifying tank input make-up water.The dust of sedimentation, foreign material can emit from the scum pipe 11 that leaves standstill the bottom, pond and the scum pipe 12 of water purifying tank bottom.In casing, the cleaning door 4 on top is used for cleaning and maintenance.Leave standstill Chi Dingshang and also can add a lid 13.
