Description

Technical Field

[0001] The utility model relates to the technical field of gas dissolving devices, in particular to an external jet gas dissolving device. Background Art

[0002] The flotation machine is a water treatment equipment that uses a dissolved air system to generate a large number of fine bubbles in the water, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density lower than that of water. The buoyancy principle is used to make it float on the water surface, thereby achieving solid-liquid separation. It uses a dissolved air device to dissolve air in water.

[0003] However, the dissolved air principle is based on the diffusion of gas molecules, so the dissolved air tank is quite large, but the dissolved air efficiency is unsatisfactory; the dissolved air tank has low strength and lacks wear-resistant, pressure-resistant and corrosion-resistant structures; it lacks an air pressure monitoring structure and its safety needs to be improved.

[0004] For example, a dissolving device on an air flotation device disclosed in Chinese patent CN219232171U introduces water and compressed air into a dissolving mixing tube through a water inlet and a compressed air inlet pipe, respectively, so that water and compressed air can be preliminarily mixed and preliminarily dissolved under a certain pressure, and then the gas-liquid mixed flow continues to move forward into the dissolving tank. By adjusting the eccentricity between the dissolving mixing tube and the dissolving tank and adding a guide plate, the gas-liquid mixed flow is injected into the dissolving tank in the form of a jet at high speed along the tangent direction of the inner wall of the dissolving tank. A water outlet pipe is arranged at the other end of the dissolving tank, so that the gas-liquid mixture can move in the dissolving tank in a high-speed spiral manner. During the high-speed spiral motion, the contact surface between water and gas is constantly changing, which is more conducive to the further dissolution of gas into water. Under the joint action of these two aspects, the gas dissolution rate of the equipment is significantly improved. At the same time, the operation is convenient and saves costs and resources. Covers are set on both sides of the dissolved gas tank for sealing. The sealing gasket set between the dissolved gas tank and the cover can improve the sealing between the cover and the dissolved gas tank. The reinforcement layer set on the dissolved gas tank can improve the strength of the dissolved gas tank and make it have higher pressure resistance. The wear-resistant casing and corrosion-resistant coating set on the inner wall of the dissolved gas tank can reduce the wear and corrosion caused by water flow scouring.

[0005] However, in the prior art, the gas and water are dissolved by relying solely on air pressure, and the relative solubility is not high.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] An external jet gas dissolving device comprises a tank body 1. A connection structure is installed on the outer surface and inside of the tank body 1. The middle of the left side of the tank body 1 is connected to the gas dissolving structure, and the right side of the tank body 1 is connected to the cooling structure.

[0029] The cooling structure includes a cooling unit and a conduction unit. The cooling unit includes a cooling box 301. A refrigerator 302 is installed on the top of the cooling box 301. A liquid injection pipe 303 is installed near the top in the middle of the right side of the cooling box 301. A cold plate 304 is connected to the bottom of the refrigerator 302. An asynchronous motor 309 is installed in the middle of the bottom of the cooling box 301. An impeller 310 is connected to the output end of the asynchronous motor 309. The conduction unit includes a disk column 305. A cold conduction column 306 is connected to the left end of the disk column 305. An insulation pipe 307 is arranged on the outer surface of the cold conduction column 306. A threaded column 308 is connected to the end of the cold conduction column 306 away from the disk column 305.

[0030] The right end of the insulation pipe 307 is fixedly connected to the middle of the left side of the cooling box 301, the end of the insulation pipe 307 away from the cooling box 301 is fixedly connected to the right end of the tank body 1, the outer surface of the cold guide plate 304 is fixedly connected to the inner wall of the cooling box 301, and the outer surface of the threaded column 308 abuts against the right end inside the tank body 1.

[0031] By setting up the cooling structure, the refrigerator 302 is used for cooling, and the cold is conducted through the cold plate 304, the disk column 305, the cold column 306, and the threaded column 308, so that the water temperature can be effectively reduced, which is more conducive to the dissolution of gas and liquid. Starting the asynchronous motor 309 to drive the impeller 310 can stir the coolant inside the cooling box 301, so that the cold transfer effect is better.

[0032] Coolant is injected into the cooling box 301 through the injection pipe 303, and the refrigerator 302 is turned on for cooling at the same time. The top fin of the cold conduction plate 304 is in contact with the cooling surface of the refrigerator 302, so that the cold can be transferred. After the transfer, the cold is in contact with the disk column 305, so that the disk column 305 transfers the cold to the threaded column 308 through the insulation pipe 307, thereby effectively cooling the dissolved gas water body, so that the efficiency of the gas solution is higher. At the same time, the asynchronous motor 309 is started to drive the impeller 310 to rotate, so that the coolant in the cooling box 301 can be stirred, so that the contact area between the coolant and the cold conduction plate 304 and the disk column 305 is increased, and the coolant is used as a medium for cold conduction, which has a better effect.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, the connection structure includes a pressure valve 101, a pressure gauge 102 is arranged on the right side of the pressure valve 101, a water outlet pipe 103 is arranged at the bottom of the pressure valve 101, a float mounting flange 104 is arranged on the right side of the pressure gauge 102, a guide plate 105 is arranged at the bottom of the float mounting flange 104, and a partition plate 106 is arranged on the right side of the guide plate 105. The pressure valve 101 and the pressure gauge 102 are installed on the top of the outer surface of the tank body 1, the float mounting flange 104 is installed on the right end of the outer surface of the tank body 1 near the top, the water outlet pipe 103 is installed on the bottom of the outer surface of the tank body 1, and the outer surfaces of the guide plate 105 and the partition plate 106 are connected to the inner wall of the tank body 1.

[0035] The gas dissolving structure includes a water inlet 201, an air inlet pipe 202 is installed near the right end of the top of the outer surface of the water inlet 201, a nozzle 203 is connected to the right end of the water inlet 201, a throat 204 is connected to the right end of the nozzle 203, a diffusion pipe 205 is connected to the right end of the throat 204, and a straight pipe 206 is connected to the right end of the diffusion pipe 205.

[0036] By controlling the air intake, the ratio of gas to water produced under a certain volume can be effectively controlled, and the formation of dissolved gas water can be completed more efficiently, ensuring the stability of dissolved gas water during operation, thereby improving the utilization value and conversion rate of microbubbles.

[0037] The treated water is transported into the tank body 1 through the water inlet 201 by a high-pressure pump. During the water transport process, air is injected into the water through the air inlet pipe 202 by an air compressor. The water and air inside the tank body 1 can be kept in balance by using the pressure valve 101 and the pressure gauge 102 to ensure that the gas content inside the water body meets the requirements. At the same time, the cooling structure is used to transfer cold energy to reduce the water temperature and ensure better gas solubility. Therefore, when the pressure is released, the air dissolved in the water will be quickly released, so that the gas is formed in the form of fine bubbles, which has a strong adsorption capacity.
