Abstract
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
The present invention relates to a kind of plating air flotation slot dissolving, specifically electroplate the Liqiud-gas mixing device that is used for making Water Soluble Gas in the air flotation slot dissolving.
Background technology
Know all that at electroplating industry the waste water that plating production process is discharged contains a large amount of impurity, directly discharging not only can pollute environment, and can cause the waste of water resource if this waste water is not handled.
Summary of the invention
The problem that the present invention will solve provides a kind of Liqiud-gas mixing device, adopts this Liqiud-gas mixing device and air flotation slot to be used, and can not pollute environment the electroplating effluent processing of evolving, and avoids the waste of water resource.
For addressing the above problem, adopt following scheme:
The characteristics of a kind of Liqiud-gas mixing device of the present invention are to comprise that water inlet pipe and Water Soluble Gas go out pipe, and water inlet pipe and Water Soluble Gas go out between the pipe has trunnion, and the caliber of trunnion goes out the caliber of pipe less than water inlet pipe and Water Soluble Gas.Be connected through compressing head between said water inlet pipe and the trunnion, the inner chamber of compressing head is taper, and its end diameter that is connected with water inlet pipe is greater than the other end.Said Water Soluble Gas goes out between pipe and the trunnion and is connected through amplifying head, and the inner chamber of amplifying head is taper, and it goes out to manage the end diameter that is connected greater than the other end with Water Soluble Gas.There is the conical nozzle concentric with it inside of water inlet pipe, and a less end and the trunnion of nozzle bore is relative.Said water inlet pipe has perforate on the tube wall between nozzle and the compressing head, be connected with air inlet pipe in the perforate.
Take such scheme, have the following advantages:
Can know by such scheme; Owing to a kind of Liqiud-gas mixing device of the present invention can mix in the process of passing through compressing head and trunnion with compressed air and produces the air water mixed liquor getting into water in it; This mixed liquor is behind the process amplifying head, and the bubble in it expands rapidly, thereby produces Water Soluble Gas.This Water Soluble Gas is introduced in the electroplating wastewater, can be made the impurity in the waste water float to liquid surface, utilize the air flotation slot cleaning shoe that the impurity of liquid surface is scraped off again, can realize that the evolution of electroplating effluent is handled.
Description of drawings
Fig. 1 is the structural representation of a kind of Liqiud-gas mixing device of the present invention;
Fig. 2 is the application of a kind of Liqiud-gas mixing device of the present invention in the air flotation slot dissolving.
The specific embodiment
As shown in Figure 1, a kind of Liqiud-gas mixing device of the present invention comprises that water inlet pipe 7 and Water Soluble Gas go out pipe 1, and water inlet pipe 7 and Water Soluble Gas go out between the pipe 1 has trunnion 3, and the caliber of trunnion 3 goes out the caliber of pipe 1 less than water inlet pipe 7 and Water Soluble Gas.Be connected through compressing head 4 between said water inlet pipe 7 and the trunnion 3, the inner chamber of compressing head 4 is taper, and its end diameter that is connected with water inlet pipe 7 is greater than the other end.Said Water Soluble Gas goes out between pipe 1 and the trunnion 3 and is connected through amplifying head 2, and the inner chamber of amplifying head 2 is taper, and it goes out to manage the 1 end diameter that is connected greater than the other end with Water Soluble Gas.There is the conical nozzle concentric with it 6 inside of water inlet pipe 7, and the less end in nozzle 6 apertures is relative with trunnion 3.Said water inlet pipe 7 has perforate on the tube wall between nozzle 6 and the compressing head 4, be connected with air inlet pipe 5 in the perforate.
As shown in Figure 2, a kind of Liqiud-gas mixing device of the present invention is loaded on air flotation slot dissolving inside, and introduces water and compressed air from water inlet pipe 7 and air inlet pipe 5 respectively.Water is accelerated through nozzle 6 back flow velocitys, and fully mixes with compressed air, flow to trunnion 3 through compressing head 4 again, makes the gas-vapor mix flow velocity increase.Gas-vapor mix liquid is gone into Water Soluble Gas and is gone out pipe 1 through amplifying head 2 is laggard, because the cross section increases suddenly, flow velocity moment reduces, and makes the air bubble expansion in the gas-vapor mix liquid, forms the Water Soluble Gas ejection.Water Soluble Gas is imported the reaction zone of air flotation slot, can react, make impurity and separated form water in the electroplating effluent, import the air flotation slot clear water zone again through the settling zone deposition of air flotation slot, and with clear water, thereby realize the purified treatment of electroplating effluent with electroplating effluent.
