Description

High-efficient inner loop air supporting device

Technical Field

The utility model belongs to the water treatment facilities field, concretely relates to high-efficient inner loop air supporting device.

Background

In the field of water treatment, the air floatation process is a common physical and chemical process and is mainly used for treating emulsified oil or micro suspended particles with relative density close to 1, which are difficult to remove by natural sedimentation or floating in wastewater. The principle is that air is introduced into the wastewater and is separated out from the wastewater in the form of micro bubbles to form a carrier, so that pollutants such as emulsified oil, micro suspended particles and the like in the wastewater are adhered to the bubbles and float to the water surface along with the bubbles to form a three-phase mixture of foam gas, water and particles (oil), and the purposes of separating impurities and purifying the wastewater are achieved by collecting the foam or scum.

Traditional air supporting device waste water flows automatically and gets into the gas-liquid mixture contact zone, through dissolving the gas water pump with the gas-liquid mixture back through bottom releaser release bubble, wrap up the suspended solid in the bubble, from the middle part directly get into the separation storehouse, the bubble of wrapping up the suspended solid carries out gas-liquid separation on separation storehouse upper portion through the strength effect suspension, but in this in-process, the reaction is inhomogeneous can appear, the bubble parcel is inhomogeneous, make partly suspended solid can not get into the microbubble and combine to carry out the come-up separation, thereby reduce the flotation separation effect of air supporting, it is poor to go out water quality.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a high-efficient inner loop air supporting device, improve bubble parcel effect, make play water quality of water improve greatly to above-mentioned prior art not enough.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high-efficient inner loop air supporting device, including dissolving gas water releaser, arrange in order by the divided district of intaking of baffle, the contact zone, disengagement zone and clear water district, a serial communication port, intake zone and contact zone lower part, upper portion intercommunication in contact zone and the disengagement zone, intake zone upper portion is equipped with a water inlet, the bottom in clear water district is equipped with an outlet pipe, be equipped with flow control valve on the outlet pipe, it sets up in the contact zone bottom to dissolve gas water releaser, the baffle middle part between intake zone and the contact zone is equipped with a baffle, the baffle is downward and cover the contact zone to one side, leave the rivers passageway between baffle end and the baffle between contact zone and the disengagement zone, disengagement zone and clear water district lower part are linked together through a inlet tube that passes the baffle, clear water district bottom is passed through the outside pipe connection jar circulating pump and is dissolved gas water gas. The dissolved air water releaser of contact zone releases the bubble, wraps up the suspended solid in the bubble, and the in-process that rises collides with the baffle repeatedly for the dissolved air bubble is easier, more even parcel suspended solid.

Furthermore, the bottom of the water inlet area, the bottom of the contact area and the bottom of the separation area are provided with a plurality of sludge discharge openings.

Further, the baffle between the water inlet area and the contact area and the baffle form an angle of 60 degrees.

Further, the flow regulating valve is an electric valve or a pneumatic valve.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses a set up a baffle in the contact storehouse, make the bottom wrap up the bubble of suspended solid and collide repeatedly with the baffle at the in-process that rises for it is easier, more even parcel suspended solid to dissolve the gas bubble, improves the effect of solid, liquid, oil separation, makes play water quality of water improve greatly.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: 1. a water inlet area; 2. a contact zone; 3. a separation zone; 4. a clear water zone; 5. a water inlet; 6. a water outlet pipe; 7. a flow regulating valve; 8. a dissolved gas water releaser; 9. a baffle plate; 10. a water inlet pipe; 11. a circulation pump; 12. an air inlet pipe; 13. a sludge discharge port.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

As shown in figure 1, a high-efficiency internal circulation air flotation device comprises a dissolved air water releaser 8, a water inlet area 1, a contact area 2, a separation area 3 and a clear water area 4 which are sequentially arranged and separated by a partition plate, wherein the lower parts of the water inlet area 1 and the contact area 2 are communicated, the middle upper part of the contact area 2 and the separation area 3 is communicated, the upper part of the water inlet area 1 is provided with a water inlet 5, the bottom of the clear water area 4 is provided with a water outlet pipe 6, the water outlet pipe 6 is provided with a flow regulating valve 7, the dissolved air water releaser 8 is arranged at the bottom of the contact area 2, the middle part of the partition plate between the water inlet area 1 and the contact area 2 is provided with a baffle plate 9, the baffle plate 9 is inclined downwards and covers the contact area 2, a water flow channel is reserved between the tail end of the baffle plate 9 and the partition plate between the contact area 2 and the separation area 3, the lower parts, the dissolved air water releaser 8 is connected with an air inlet pipe 12. The dissolved air water releaser 8 of the contact area 2 releases air bubbles, wraps the suspended matters in the air bubbles, and repeatedly collides with the baffle 9 in the rising process, so that the dissolved air bubbles can wrap the suspended matters more easily and more uniformly.

The bottom of the water inlet area 1, the contact area 2 and the separation area 3 is provided with a plurality of sludge discharge ports 13, a baffle plate between the water inlet area 1 and the contact area 2 forms a 60-degree angle with the baffle plate 9, and the flow regulating valve 7 is an electric valve or a pneumatic valve.
