Problems solved by technology
[0002] It is known in the electroplating industry that the wastewater discharged from the electroplating production process contains a large amount of impurities. If this wastewater is discharged directly without treatment, it will not only pollute the environment, but also cause waste of water resources.

Embodiment Construction
[0010] Such as figure 1 Shown, a kind of gas-liquid mixing device of the present invention comprises water inlet pipe 7 and water-soluble gas outlet pipe 1, throat pipe 3 is arranged between water inlet pipe 7 and water-soluble air outlet pipe 1, and the pipe diameter of throat pipe 3 is smaller than water inlet pipe 7 and water-soluble gas outlet pipe 1. The diameter of the water-soluble gas outlet pipe 1. The water inlet pipe 7 is connected with the throat pipe 3 through the compression head 4, the inner cavity of the compression head 4 is tapered, and the diameter of the end connected to the water inlet pipe 7 is larger than the other end. The water-soluble gas outlet pipe 1 is connected with the throat pipe 3 through the enlargement head 2, and the inner chamber of the enlargement head 2 is tapered, and the diameter of one end connected with the water-soluble air outlet pipe 1 is larger than the other end. The inside of the water inlet pipe 7 has a conical nozzle 6 concen...

The invention relates to a gas-liquid mixing device which can be arranged in a solution tank in an electroplating gas floating tank and is used for manufacturing water soluble gas. The gas-liquid mixing device is characterized by comprising a water inlet pipe and a water soluble gas outlet pipe, wherein a venturi is arranged between the water inlet pipe and the water soluble gas outlet pipe, and the diameter of the venturi is less than those of the water inlet pipe and the water soluble gas outlet pipe. The water inlet pipe is connected with the venturi by virtue of a compression head, the inner cavity of the compression head is conical, and the diameter of one end, connected with the water inlet pipe, of the compression head is more than that of the other end of the compression head. The water soluble gas outlet pipe is connected with the venturi by virtue of an amplifying head, the inner cavity of the amplifying head is conical, and the diameter of one end, connected with the water soluble gas outlet pipe, of the amplifying head is more than that of the other end of the amplifying head. A conical nozzle concentric with the water inlet pipe is arranged in the water inlet pipe, and one end with the less diameter of the nozzle is opposite to the venturi. A hole is formed on the pipe wall between the nozzle and the compression head and is connected with a gas inlet pipe. When the gas-liquid mixing device is matched with the gas floating tank for use, electroplating effluents can be subjected to evolution treatment, the environment pollution is avoided, and the waste of water resources is avoided.
Description
technical background [0001] The invention relates to an air-dissolving tank for an electroplating air flotation tank, in particular to a gas-liquid mixing device for producing water-soluble gas in the air-dissolving tank for an electroplating air flotation tank. Background technique [0002] It is known in the electroplating industry that the wastewater discharged from the electroplating production process contains a large amount of impurities. If this wastewater is discharged directly without treatment, it will not only pollute the environment, but also cause waste of water resources. Contents of the invention [0003] The problem to be solved by the present invention is to provide a gas-liquid mixing device, which can be used in conjunction with an air flotation tank to carry out evolutionary treatment of electroplating waste liquid without polluting the environment and avoiding waste of water resources . [0004] In order to solve the above problems, the following solu...
