Abstract

The separator for separating oil from oil waste water or separating two kinds of liquid in different specific weight is equipped with one automatic control float valve comprising flat, water pressure sealing plug and water drainage port. The oily waste water is made to enter from the upper part of the separator, and this can reduce the distance for oil to float to the upper part of the separator and shorten the separating time. The float is controlled by the water level inside the separator to move up and down to control the opening of the water pressure sealing plug, so that water drains from the bottom while oil floats inside the separator. After the separated oil reaches some height, oil is exhausted via the oil exhaust valve for collection. The separator is small in size and great in separating capacity and has no power consumption.

Description

Automatic control float valve oily-water seperating equipment

One, art field:

This invention belongs in field of environment protection the oily waste water treatment technology and carries out the oily water separation technique field.

Two, art background:

3, the major products [Sichuan environment 2000.1] of China's environment industry Situation and enviromarketing urgent need.

Three, goal of the invention:

Be used for the waste water of oil-containing and grease is carried out the fluid separation applications processing that oil removal is handled, is used to carry out two kinds of different specific weights.Four, Fa Ming content:

Automatic control float valve oily-water seperating equipment is to be used for waste water to oil-containing and grease to carry out oil removal and handle, be used to carry out the device that the fluid separation applications of two kinds of different specific weights is handled.Have that wastewater treatment capacity to oil-containing and grease is big, equipment volume is little, oil removal separative efficiency height to oil and grease in the waste water, the no energy consumption of device processes waste water operation, equipment transportation, convenient for installation and maintenance, characteristics such as isolated oil and grease water content are low, recovery convenience.

Main feature is:

1, by buoyancy device or ball float, hydraulic pressure sealing-plug, buoyancy device or ball float and hydraulic pressure sealing-plug connection rope (bar) and discharge outlet formation automatic control float valve.

2, oil and the grease to proportion＜1 mixes dispersed oil, the oil slick that forms, oil removal separation rate＞90% with water;

3, this no oil skimmer of device and mud scraper do not have mechanical wearing terrain.

When 4, handling oily waste water, the unpowered energy resource consumption of equipment.

5, the oily waste water treating capacity is big, and equipment volume is little, and floor space is few, and is in light weight.

6, the device clean and maintenance is convenient, can carry out spoil disposal simultaneously when the work operation and clean.

7, oil and grease reclaim conveniently, recovered oil and grease water content＜10%;

Automatic control float valve oily-water seperating equipment principle is:

Automatic control float valve oily-water seperating equipment has multiple structural approach, shown in figure (1) and figure (2).Among the figure;

1, container; 2, oily waste water import; 3, filter the distributing net; 4, container cover; 5, ball float;

6, hydraulic pressure sealing; 7, discharge outlet; 8, buoyancy device or ball float and hydraulic pressure sealing-plug connection rope (bar);

9, draining valve; 10, swash plate; 11, draining valve; 12, oil extraction dirt water valve; 13, oil reservoir;

14, water layer;

1, from the waste water import oily waste water is sent into, oily waste water is the distributing net after filtration, after filtering the bulky grain thing of easy obstruction, oily waste water is evenly distributed on the large tracts of land of filter screen, reduce the disturbance degree of depth of the impulsive force of influent waste water to noodle in the container, whereabouts waste water makes the oil of container bottom and water to leaving standstill through swash plate, and elaioleucite does not have decline power can not drop to the container bottom.

Automatic control float valve oily-water seperating equipment advances oily waste water from top, because of having reduced the path distance that makes little elaioleucite float to container top in leaving standstill water, has dwindled the floating interval of floating dock of elaioleucite, has also just reduced the disengaging time of oil with water.The grease that swims on the water surface can adsorb the little elaioleucite that has just entered rapidly, accumulates oil slick.The water that enters in the container is subjected to gravity effect, and the decrease speed of water is fast, separates with oil rapidly, be deposited to oil below.Proportion＜1 because of oil, the decline degree of depth is only entered container decline impulsive force effect of depth, after the decline impulsive force is offset by the resistance of water, grease is floated by buoyancy of water, the swash plate degree of depth that impulsive force reaches when entering so elaioleucite can only reach waste water, can not drop to the bottom of container, the surface viscosity of oil is big, and vibration is disturbed in the impact that swims in the time of alleviating oily waste water on the water surface and enter.

When 2, the oily waste water height in entering container is higher than the height of buoyancy device or ball float and hydraulic pressure sealing-plug connection rope (bar), the buoyancy of profit makes the ball float come-up, remove on the hydraulic pressure sealing-plug of ball float connection rope (bar) pulling sealing discharge outlet and open, make separate drop to container bottom water outside the discharge outlet amount discharge container, isolated oil is appointed the floating container top that is retained in.When a large amount of oily waste waters constantly enters container, oil is constantly separated with water, and water is constantly discharged.Along with the oily waste water quantitative changeization that enters container, ball float constantly fluctuates, and pulling hydraulic pressure sealing-plug moves up and down regulates opening water discharge mouth size, regulates discharge water and advances the water yield that waste water adapts.After no oily waste water enters container, water level descends, at this moment the interior profit height of container is lower than the height of ball float and hydraulic pressure sealing-plug connection rope (bar), the hydraulic pressure sealing-plug lose ball float on move pulling force, the hydraulic pressure sealing-plug is descended by the pressure of self gravitation, water and the influence of draining attraction, with discharge outlet sealing, isolated oil and part water can not be discharged, oil is retained in the container.

Utilization can improve the separation treatment efficiency to profit in the method for container bottom float valve automatic control draining, and elaioleucite is can not be deposited to container bottom because of buoyancy of water leaving standstill under the undirected down situation that impulsive force is disturbed relatively.When oil is subjected to the pressure that continuous descending water produces, because of the Inlet and outlet water balance, this pressure is balance also, there is the power that elaioleucite is upwards floated all the time in buoyancy of water, so certain degree of depth of catchmenting is arranged when container, the shock vibration when separating the water that drops to container bottom and not entered by waste water, outside the successive amount discharge container of discharge outlet, realize continuous processing big yield oily waste water, reduced volume of a container greatly, realized the continuous processing procedure of automatic control float valve water-oil separating.

By draining and flushing, contaminated possibility is very little because of constantly for hydraulic pressure sealing-plug and discharge outlet.The hydraulic pressure sealing-plug is subjected to the lifting pulling of ball float to regulate the size that discharge outlet is opened, constantly regulate displacement, when no oily waste water entered, the hydraulic pressure sealing-plug was subjected under the situation of water pressure in suitable counterweight and surface, can well seal discharge outlet, make isolated oil can not leaked out container.

When 3, isolated oil is kept somewhere the height of draining valve in container, open draining valve and drain the oil, oil extraction is closed draining valve after finishing, continuation is sent oily waste water into container, above repeatedly process reaches oily waste water is carried out oil removal or water-oil separating processing, and reclaims waste oil or separating oil.

4, the particle that contains part proportion＞1 in waste oil water can precipitate in container after handling the oily waste water certain hour, forms greasy filth in the bottom, needs to remove.Insert container bottom with high-pressure water pipe during removing, or at the default syringe pipe of container bottom, the greasy filth with the high pressure water washing container bottom makes greasy filth floating, greasy filth with water outside the automatic amount discharge container of discharge outlet.Removing greasy filth can not influence the oil slick on container top, can not influence the work of equipment normal process oily waste water yet.

5, low and contain under the high condition of grease in temperature, the reply container is incubated or heats, and water is not freezed and makes grease noncondensing.
