Description

High efficiency particulate air filter

(1) technical field

The utility model relates to a kind of filter plant, specifically a kind of suspended particles that are used for separating water inlet, the high efficiency particulate air filter of suspended impurity content in the reduction water inlet.

(2) background technology

Use at present filtering material filter as filter plant, the suspended particles that are used for separating water inlet are comparatively general, it have water quality treatment wide, produce characteristics such as water quality stabilizing; But the filtrate in the existing filtering material filter mostly is quartz sand, ANTHRACITE FILTER MEDIA, uses this media filtration precision low, and the filter bed pollutant holding capability is little, and the rate of filtration is low.Further improved afterwards and adopted the synthetic filtrate of a kind of fiber, though this filtrate can remedy the defective that conventional particles media filtration precision is low, the filter bed pollutant holding capability is little, filtering velocity is low, but it is because little with the difference in specific gravity of water, place this synthetic fibers formed body filtrate cleaning performance is poor, and fiber easily runs off during backwash.

(3) summary of the invention

Technical assignment of the present utility model is at the deficiencies in the prior art, provides a kind of filtering accuracy height, the rate of filtration is fast, pollutant holding capability is big, the backwash water consumption rate is low, add the high efficiency particulate air filter that dose is low, operating cost is low and floor space is little.

The technical scheme that its technical problem that solves the utility model adopts is:

High efficiency particulate air filter, comprise the filter tank body and fill in self adaptation comet formula fiber filtering among the filter tank body, rational backwash space is left in the top of self adaptation comet formula fiber filtering, in tank body, also be provided with run through self adaptation comet formula fiber filtering on three-way pipe and following three-way pipe, the wherein two-port of last three-way pipe is positioned at the inner chamber middle and lower part of filter tank body, be respectively and just wash water inlet and backwash delivery port, the 3rd port of last three-way pipe stretches to the interior top of chamber of filter tank body; The wherein two-port of following three-way pipe is positioned at the inner chamber middle and lower part of filter tank body, is respectively the backwash water inlet and is just washing out the mouth of a river, and the 3rd port of following three-way pipe stretches out from the bottom of filter tank body for just washing discharge outlet.

Above-mentioned high efficiency particulate air filter, the bottom of its filter tank body is provided with air inlet, also is provided with the blast pipe that runs through self adaptation comet formula fiber filtering in the filter tank body.

Above-mentioned high efficiency particulate air filter, its self adaptation comet formula fiber filtering is a kind of filtering material that is made of fibre bundle and tow joint, is comet formula fiber filtering.This comet formula fiber filtering is that fiber filtering is processed into an end is solid, the comet formula structure that an end is loose.Because by plastics, pottery, rubber or the metal intelligent nuclear proportion proportion greater than comets tail, intelligent nuclear has played the densification effect to fibre bundle when filtering, thereby improved the retaining power of filter bed.During backwash because the difference in specific gravity of intelligent nuclear and comets tail, the comets tail fiber is whole to be swung with the backwash current, produce stronger knockout press, mutual collision between the comet body simultaneously, also having aggravated filtrate suffered machinery in water uses firmly, the irregular section of intelligent nuclear makes the comet body produce rotation, the mechanicals efforts that filtrate is subjected to when having strengthened backwash under the effect of backwash current.The common result of above-mentioned several our power makes the suspended particulate attached to fiber surface be easy to come off, thereby has greatly improved the wash degree of filtrate, has also reduced the backwash water consumption.

During filtration, current are entered by filter top, from top to bottom by behind the self adaptation comet formula fiber filtering packed layer, clear water is flowed out by filter bottom, dirt of holding back when filtering layer and impurities accumulation are to a certain degree the time, when pressure reduction is increased to certain numerical value up and down by the gauge measurement filtering layer, stop to filter the beginning backwash.Backwash water and air or separately water, use air separately, feed by filter bottom, to break up because of the filter bed that filters compacting, because the characteristic of self adaptation filtrate, be easy to come off attached to the dirt on the filtrate, get clean purpose express developed thereby reach, backwashing water is discharged by the filter top.In backwash process, stop to filter, filter again after subject to backwash the finishing.

High efficiency particulate air filter of the present utility model compared with prior art, the beneficial effect that is produced is:

1) filtering accuracy height: the clearance to suspension in the water can reach more than 95%, and impurity such as larger molecular organics, virus, bacterium, colloid, iron are had certain removal effect.

2) rate of filtration is fast: being generally 40m/h, reaching as high as 60m/h, is more than 3 times of normal sands filter.

3) pollutant holding capability is big: being generally 15-35Kg/m3, is more than 4 times of normal sands filter.

4) backwash water consumption rate is low: the backwash water consumption is less than the 1-2% of cycle drainage amount.

5) add that dose is low, operating cost is low: because filter bed structure and filtrate self, flocculant dosage is the 1/2-1/3 of routine techniques.The raising of cycle aquifer yield, ton water running expense also reduces thereupon.

6) floor space is little: produce the identical water yield, floor space is below 1/3 of normal sands filter.With Economic and Efficiency Analysis excellent effect of the present utility model is described below:

Be applied to 10000 cubic metres of-50000 cubic metres of middle-size and small-size water factories of day output, can save the coagulating basin and the sedimentation basin that require in the conventional process flow, integrate coagulation, precipitation, filter.The water factory of 50000 cubic metres of outputs meter per diem, the cost of coagulating basin is 1,500 ten thousand yuan, the cost of sedimentation basin is 1,200 ten thousand yuan also near 1,500 ten thousand yuan and adopt the cost of DA high efficiency particulate air filter, then saves totally 1,800 ten thousand yuan of costs of equipment.Moreover, it also saves the floor space of equipment greatly, if then need 4000 square metres of floor spaces by conventional process flow, this project product only needs 300 square metres of the device spaces, then can save and take up room 3700 square metres, and this project product can be realized the unmanned automatic operating.Set up automation water factory about one 500 square metres can effectively improve in resident's the watering condition of samll cities and towns and vast rural area.

Certain company's sewage disposal system and for example, former design adopts 2 sand filters and 5 water pumps, handle the other drainage of circulation of 40m3/h, take up an area of 11 * 9=99m2, use high efficiency particulate air filter of the present utility model instead, only get final product with 800 1 of φ, water pump reduces to 2, floor space is reduced to 45 * 11=49.5m2, can also invest by corresponding minimizing pipe valve, and the backwash water consumption can be saved more than 50%.
