Abstract
The invention discloses a pneumatic flotation device, comprising an air floater main body (6), wherein a gas-water mixing pump (1), a water pump inlet (2), a mixing tank (3), a pressure gauge (4) and a pipeline valve (5) are installed at the lower part of the air floater main body (6); an effluent weir (13), an exhaust hood (9), a water collecting sump (14) and a blow pipeline (7) are installed on the upper part of the air floater main body (6); a plurality of universal swing joints (8) and air concentrators (16) arranged thereon are evenly distributed and installed on the blow pipeline (7); and a scum collector (10), a vertical flow tank (11), a deslagging bucket connecting joint (12) and a deslagging tube (15) are installed on the central axis of the air floater main body (6). The invention has the advantages that the gas-water mixing pump of the invention is used to replace the original dirty water pump and the original aerating system, thus omitting a dissolved air vessel and a fan (or air compressor) and reducing the air dissolving time. The pneumatic scum collection system and the floatation scum collector of the invention solve the easily occurred problems that a mechanical scraper is difficult to collect recovered scum totally and the scum has high moisture content.
Description
Technical field:
The invention relates to the pressure flotation unit, particularly about the pneumatic type flotation unit.
Background technology:
General pressure flotation facility is to be made of dissolving, floation tank.The main effect of dissolving is, gas is dissolved in the water, therefore needs certain dissolution time and pressure, generally is 20-30 minute, and pressure is 0.3-0.5.The effect of floation tank is that the Shuitu of having dissolved gas so reduces pressure, and water-soluble gas is discharged with the micro-bubble form, has reached the purpose of removing impurity (as oil, suspension etc.) in the water.Wrapped up on the impurity of bringing up climbs up on top of the water by bubble, with mechanical scraper plate it is scraped impurity feeder, otherwise processed then again.There is following shortcoming in above-mentioned facility: dissolving belongs to press device, and certain manufacturing requirement is arranged, simultaneously volume also big (generally be will handle the water yield " cubic meter/hour " 1/2nd).Floation tank floats at the water surface because sump oil that is floatingly selected and flotation agent (generally mostly being aluminium polychloride and polyacrylamide) form scum silica frost when handling oil-polluted water, and is very easily broken.When mechanical scraper plate scrapes scum silica frost and it is scraped in the process of scum silica frost feeder, part scum silica frost or sink in the water because of vibrations, or because of sternly not missing from the scraper plate both sides at the scraper plate two ends.When scraper plate scrapes the cell wall of scum silica frost feeder, because the minor variations of the water level that the fluctuation of water yield size causes is high slightly as water level, then there are a large amount of water and scum silica frost together to scrape into the scum silica frost feeder, caused difficulty to dross dehydration.As low slightly, then there is a large amount of scum silica frost might not advance the scum silica frost groove and sinks under water once more, can collect to scum silica frost and bring very big difficulty.In addition, if contain volatile material in the water, the quality of air environment on the floation tank is with very poor.As want to improve environment and floation tank is added a cover cover, can produce adverse influence to corrosion and inspection, the maintenance of scraping the slag facility again.
Also have a kind of newer flotation facility in the market, generally be called concavo-concave air supporting.Be characterized in,, air sucked in the water, through stirring air is broken into micro-bubble and is scattered in the water, enter floation tank then and carry out flotation by the high speed rotation of impeller in water.But it is scraped the slag form and still adopts machinery to scrape slag.It is identical with aforesaid pressure flotation that the slag facility is scraped in its floation tank agent.This technology has just been saved dissolving than the former, and needs supporting related facility because of pressurizeing.
Summary of the invention:
The objective of the invention is to solve the problem that above-mentioned prior art exists and a kind of pneumatic type flotation unit is provided.
The technical solution of pneumatic type flotation unit of the present invention is by air-water mixing pump (1), pump intake (2), blending tank (3), Pressure gauge (4), pipeline valve (5), Air-float separator main body (6), blowing pipeline (7), universal swinging joint (8), hood (9), scum collector (10), perpendicular stream jar (11), scummer connects joint (12), effluent weir (13), water leg (14), scum pipe (15), form, it is characterized in that air-water mixing pump (1) being installed pump intake (2), blending tank (3) in the bottom of Air-float separator main body (6), Pressure gauge (4), pipeline valve (5) is equipped with effluent weir (13) and hood (9), water leg (14) on the top of Air-float separator main body (6), blowing pipeline (7), go up uniform several universal swinging joint (8) and the blowing head (16) mounted thereto of being equipped with at blowing pipeline (7), scum collector (10) is installed on the axis of Air-float separator main body (6), perpendicular stream jar (11), scummer connects joint (12), scum pipe (15).
The invention has the advantages that:
1, the air-water mixing pump used of the present invention is replaced original sewage pump and refueling system, this pump can suck the pump housing and dissolved under pressure with air simultaneously when sending water, by the pipeline current limliting gas, water are fully mixed once more, save dissolving and air blast (or air compressor), also reduced dissolved air time.
2, pneumatic scum silica frost gathering system of the present invention and unsteady scum collector, solved that mechanical scraper plate easily goes out be difficult to all collect reclaimed scum silica frost and the high difficult points of scum silica frost moisture content.
3, the present invention has accomplished flotation facilityization, closure, and the dusty gas easily collecting is for its subsequent treatment has been created condition, favourable to improving environment.
4, the present invention also solved the flotation facility airtight after, original machinery is scraped the slag fault and is difficult to timely discovery, machinery to scrape slag equipment perishable and go wrong and be difficult to the problem of maintenance in time.
5, the present invention is simple to operate, and is reliable, and operation needs personal management and maintenance hardly automatically.
