Abstract
The utility model relates to a device for purifying water in an air flotation method. Pressurized air is not generated by an air compressor. An automatic air adding pipe is arranged on an outlet pipe of the water pump for water supply of a pressure air dissolving tank. Water operated by the water pump and compressed air are together pressed to the pressure air dissolving tank. Solid and liquid are separated in an air flotation separation system to obtain the purpose of purifying water quality. The utility model has the advantages of saving the investment cost of air compressors, improving noise pollution and operating conveniently.
Description
The utility model is the pressure floatation air purifier of no air compressor machine, belongs to control device in the physics.
As everyone knows, the pressure air-dissolving device of existing pressure floatation air clean water treatment is made up of pressure pump, air compressor and pressure air-dissolving tank three parts, implement this covering device and must increase the pneumatics unit cost of equipment in the purified water treatment device, and when start, gas in the pressure air-dissolving tank,, liquid balance-conditioning system trouble.
The purpose of this utility model is to save the pneumatics unit in the pressure floatation air purifier, directly installs an automatic blowdown pipe and Controlling System on pumping line additional, and device is simple, noise pollution and the energy efficient of reducing easy to adjust.
The utility model is achieved like this, after installing an automatic blowdown pipe on the outlet pipe of water pump additional, can with the function collection of air compressor machine and water pump one, pump operation supplies water simultaneously, pressurized air is filled in pressure air-dissolving tank, utilize the effect of filler in the dissolving to generate dissolved air water, dissolved air water is continuously delivered to molten gas release system automatically by the pressure of compressed gas in the pressure air-dissolving tank, in the dissolved air flotation system, reach the solid, liquid separating effect, finish pressure floatation air water purifying purpose.
Elaborate below in conjunction with accompanying drawing: water pump 1 among the figure, blowdown pipe 2, vacuum breaker 3, pressure air-dissolving tank 4, liquid level meter 5, filler 6, constant pressure valve 7, pressure relay 8, magnetic valve 9 is formed, on the outlet water pipe of axial flow pump, install blowdown pipe additional, a vacuum breaker is installed on the pipeline between blowdown pipe and the pressure air-dissolving tank, the aqueous reflux that prevents pressure air-dissolving tank goes back, there is a magnetic valve air supply tank upper end, magnetic valve is by the pressure relay trip switch on pressure air-dissolving tank next door, during the water pump stall, magnetic valve is opened, in the air admission blowdown pipe, during starting mode of pump, closed electromagnetic valve, air in the blowdown pipe promptly by the hydraulic pressure of exit of pump in dissolving, be provided with one group of porous sieve plate at the middle part of pressure air-dissolving tank, heap has a lot of garland fillers above the sieve plate, to increase gas, the contact area of liquid two-phase is along with the pressure air-dissolving tank water level rises.Air is compressed in the pressure air-dissolving tank, and pressure increases, and the dissolved air amount also increases in the water, treats that pressure rises to 03～04MPa/cm
2The time, pressure relay works, water pump is shut down, dissolved air water is under the pressurized air effect in the pressure air-dissolving tank, in dissolving, flow to the dissolved air release the molten gas release system, decompression discharges, can produce a large amount of micro-bubbles, floating on the water surface, micro-bubble in the floating process of water in air flotation pool in the pending water suspended substance adhesion and aggregation get up to float to the water surface, draw together out by drawing together the foam machine, reach the water purification purpose, during termination of pumping, the magnetic valve on the blowdown pipe reopens, be full of air in the blowdown pipe again, along with liquid level in the pressure air-dissolving tank reduces, the process pump of pressure relay starts above-mentioned action again, and circulation opens and closes like this, automatically carry out the while to pressure air-dissolving tank water supply air feed, uninterruptedly supply with the pressure floatation air water purification purpose that dissolved air water is realized no air compressor machine to molten gas release system.It not only adopts in water supply and sewage work, in the also widespread use of engineering of water treatment of field of environment protection.
Claims (1)
1, a kind of pressure floatation air purifier that constitutes by water pump, pressure air-dissolving tank, it is characterized in that pump outlet is equipped with a blowdown pipe, there is a magnetic valve blowdown pipe upper end, magnetic valve is by the pressure relay trip switch on pressure air-dissolving tank next door, and the Controlling System of being made up of pressure relay, magnetic valve is controlled the work of pressure floatation air purifier.
