Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes, and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figure 1 shown, a high-efficiency boiler desulfurization device includes a desulfurization tank body 1. The right side in the middle of the outer surface of the desulfurization tank body 1 is fixedly connected with a liquid injection pipe 2. The lower end of the outer surface of the desulfurization tank body 1 is fixedly connected with a support assembly 3, which can support the desulfurization tank body 1 and the drive mechanism 4. The lower part of the support assembly 3 is fixedly connected with a drive mechanism 4, which can extract the waste gas to be purified. The middle of the inner cavity bottom wall of the desulfurization tank body 1 is fixedly connected with a gas transmission mechanism 5, which can support the aeration mechanism 6 and at the same time transport the extracted waste gas. A number of aeration mechanisms 6 are fixedly connected in an annular array inside the gas transmission mechanism 5, which can fully blow out the extracted waste gas into the desulfurization liquid in the accommodation cavity 9 for desulfurization. The upper side outside the gas transmission mechanism 5 is fixedly connected with an anti-backflow mechanism 7, which can prevent backflow during the operation of the liquid injected into the accommodation cavity 9. The upper part of the anti-backflow mechanism 7 is fixedly connected with an air-dispersing mechanism 8, which can collect and discharge the desulfurized gas. The lower part of the inner cavity of the desulfurization tank body 1 is provided with an accommodation cavity 9.

[0023] In order to achieve the purpose of supporting the desulfurization tank body 1 and the drive mechanism 4, refer to Figure 2 , the support assembly 3 includes a protective base 31, which can protect and support the desulfurization tank body 1. A number of support columns 32 are fixedly connected in an annular array at the lower end of the outer surface of the protective base 31, and the lower ends of the number of support columns 32 are jointly fixedly connected with a chassis 33.

[0024] In order to achieve the purpose of extracting the waste gas to be purified, refer to Figure 2, the driving mechanism 4 includes a motor 41, which can drive the fan 42. The output end of the piston rod of the motor 41 is fixedly connected to the fan 42. The upper part of the outer surface of the fan 42 is fixedly connected to an air supply pipe 43, and the left part of the outer surface of the fan 42 is fixedly connected to an air extraction pipe 44. The lower ends of the outer surfaces of the motor 41 and the fan 42 are jointly fixedly connected to the upper part of the outer surface of the chassis 33.

[0025] When it is necessary to extract the sulfur-containing waste gas, the driving motor 41 drives the fan 42 to start working, so that the air extraction pipe 44 sucks in the sulfur-containing waste gas and transports it through the air supply pipe 43 into the inner cavity of the first gas transmission pipe 52.

[0026] In order to support the aeration mechanism 6 and transport the extracted waste gas at the same time, refer to Figure 3 , the gas transmission mechanism 5 includes a fixed sleeve 51, which can support the aeration mechanism 6 and isolate the desulfurization liquid injected into the inner cavity of the accommodation chamber 9. In the middle of the inner cavity of the fixed sleeve 51, there is a fixedly connected first gas transmission pipe 52, which can transport the extracted sulfur-containing waste gas through the first gas transmission pipe 52 into the inner cavities of a number of connecting pipes 61.

[0027] In order to fully blow out the extracted waste gas into the desulfurization liquid in the inner cavity of the accommodation chamber 9 for desulfurization, refer to Figure 4 , the aeration mechanism 6 includes a connecting pipe 61. In the middle of the inner cavity of the connecting pipe 61, there is a fixedly connected solenoid valve 62. On the side of the outer surface of the connecting pipe 61 away from the first gas transmission pipe 52, there is a fixedly connected second gas transmission pipe 63. At intervals on the side of the second gas transmission pipe 63 away from the first gas transmission pipe 52, there are a number of exhaust nozzles 64 fixedly connected, and the number of exhaust nozzles 64 communicates with the inner cavity of the accommodation chamber 9.

[0028] When the sulfur-containing waste gas transported through the first gas transmission pipe 52 enters the inner cavities of a number of connecting pipes 61, the solenoid valves 62 in the inner cavities of the number of connecting pipes 61 are remotely controlled to open, so that the sulfur-containing gas is discharged through the inner cavities of the corresponding second gas transmission pipes 63 and the number of exhaust nozzles 64, so that the sulfur-containing gas discharged through the number of exhaust nozzles 64 is blown into the desulfurization liquid in the inner cavity of the accommodation chamber 9.

[0029] In order to prevent backflow of the liquid injected into the inner cavity of the accommodation chamber 9 during operation, refer to Figure 4 , the anti-backflow mechanism 7 includes a fixed disc 71. On the outer side of the lower end of the outer surface of the fixed disc 71, there are a number of conical shells 72 fixedly connected in an annular array, which can transport the desulfurized gas through the number of conical shells 72 into the inner cavity of the fixed disc 71. At the same time, because the number of conical shells 72 is conical, the backflow of the sulfur-containing liquid is effectively prevented. The middle part of the lower end of the outer surface of the fixed disc 71 is fixedly connected to the upper end of the outer surface of the fixed sleeve 51, and the inner cavities of the number of conical shells 72 are jointly connected to the inner cavity of the accommodation chamber 9.

[0030] For the purpose of collecting and discharging the gas after desulfurization, refer to Figure 4 , the gas dispersing mechanism 8 includes a gas collecting pipe member 81. A discharge pipe 82 is fixedly connected to the middle of the upper end of the outer surface of the gas collecting pipe member 81, which can realize the function of transporting the gas after desulfurization to the outside. The outer surface of the gas collecting pipe member 81 is fixedly connected to the upper part of the inner cavity of the desulfurization tank body 1, and the lower end of the outer surface of the gas collecting pipe member 81 is fixedly connected to the upper end of the outer surface of the fixed disc 71.

[0031] It should be noted that the specific installation methods of the motor 41 and the fan 42, the connection method of the circuit, and the control method in the present invention are all conventional designs, and the present invention will not be elaborated in detail.

[0032] The working principle of the present invention: First, an appropriate amount of desulfurization liquid is injected into the inner cavity of the accommodating cavity 9 through the liquid injection pipe 2. Then, the driving motor 41 drives the fan 42 to start working. The sulfur-containing waste gas is extracted through the air extraction pipe 44 and then discharged into the inner cavity of the first gas transmission pipe 52 through the air supply pipe 43. Then, the solenoid valves 62 in the inner cavities of a plurality of connecting pipes 61 are opened, so that the extracted sulfur-containing gas is blown out through a plurality of exhaust nozzles 64 into the desulfurization liquid in the inner cavity of the accommodating cavity 9. The gas after desulfurization will be transported upward through a plurality of conical shells 72 into the inner cavity of the gas collecting pipe member 81, and finally discharged to the outside through the discharge pipe 82.
