Description

Anti-blocking device of dissolved air releaser for pressurized dissolved air floatation water treatment

Technical Field

The utility model relates to a pressurization dissolves gas air supporting water treatment technical field, specifically is a dissolve gas releaser and prevent stifled device for in pressurization dissolves gas air supporting water treatment.

Background

The existing dissolved air releaser mainly comprises a TS type, a TJ type and a TV type.

The TS type dissolved air releaser is a first generation air release product, belongs to a low-pressure dissolved air releaser, is a domestic original special releaser, can release a large amount of micro bubbles meeting the air floatation water purification requirement under low pressure, but is continuously eliminated due to no anti-blocking measures, and is subsequently provided with a water ejector vacuumizing anti-blocking facility on the basis, thus obtaining the TJ type dissolved air releaser after improvement.

When impurities in water block the releaser to affect normal air release, the TJ type dissolved air releaser can start the water ejector to work. Negative pressure is generated in the vacuum tube to lift the reed, so that the water flow passage is enlarged to discharge impurities. After the washing is carried out for a period of time, the gate is closed, and the reed can be reset and put into normal operation.

When the TV type dissolved air releaser works normally, the vibrating disk keeps a clearance with the fixed disk in the best working state due to the pressure of the spring. When the impurity in water blocks the releaser and can not release gas normally, the air source of the air compressor can be connected to make the vibration disk fall for a certain distance, so that the water flow channel is enlarged, the impurity is quickly washed away by the dissolved gas water, after about several seconds, the air source is cut off and the air release valve is opened to release gas, so that the vibration disk is reset and is in a working state again.

The existing device for pressurizing and dissolving air flotation water treatment for wastewater has more attached anti-blocking devices and complex anti-blocking operation.
