Description

Technical Field

[0001] This utility model relates to the field of acid gas purification technology, specifically to an acid gas emission device. Background Technology

[0002] Industrial production is accompanied by environmental problems. In industrial production processes such as electroplating, chemical processing, and pickling, a large amount of acid mist gas is generated. If acid mist gas is directly emitted into the air, it will cause air pollution, ultimately harming people's health and the ecological environment.

[0003] For example, the acid mist purification tower with uniform gas distribution proposed in document number "CN214075926U" describes, in paragraph

[0026] , that "the acid gas is forced into the inlet, enters the middle of the tower body along the extension pipe, and moves upward from the middle under the obstruction of the guide block. The gas is then diverted from the center outward by the cross-shaped diversion plate above, so that it is evenly distributed inside the tower body and fully contacts the metal corrugated packing layer impregnated with the chemical solution, resulting in a neutralization reaction." This process involves the acid gas passing through each layer of metal corrugated packing and contacting the neutralizing liquid distributed within the metal corrugated packing layer to undergo a neutralization reaction. However, this method of allowing the gas to pass through the metal corrugated packing layer cannot ensure sufficient contact between the neutralizing liquid and the gas, meaning that the acid gas and the neutralizing liquid cannot be fully mixed, resulting in a mediocre purification effect. Therefore, we propose an acid gas emission device. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: an acidic gas emission device, including a mixing tank 10, on the inner side of which at least one atomizing nozzle 18 and at least one blowing head 19 are installed. The blowing head 19 is used to spray acidic gas, while the atomizing nozzle 18 is used to atomize an alkaline neutralizing liquid that neutralizes the acidic gas, such as... Figure 4 As shown, the blowing head 19 and the atomizing nozzle 18 should be positioned opposite each other so that the acidic gas and the atomized neutralizing liquid can be flushed together and mixed quickly.

[0023] Two preheating pipes 5 are also provided on one side of the atomizing nozzle 18. One preheating pipe 5 is connected to the atomizing nozzle 18 through a pipe, and the other preheating pipe 5 is connected to the air blowing head 19 through a pipe. Each preheating pipe 5 is equipped with a heating device to heat the acidic gas and neutralizing liquid passing through the preheating pipe 5. It should be emphasized that the preheating pipe 5 connected to the atomizing nozzle 18 is equipped with an induced draft fan, which quickly guides the acidic gas into the preheating pipe 5; while the preheating pipe 5 connected to the air blowing head 19 is equipped with a high-pressure delivery pump, which quickly delivers the neutralizing liquid into the preheating pipe 5. Therefore, the acidic gas and neutralizing liquid passing through the preheating pipe 5 can be heated to the set temperature, and then the acidic gas and the atomized neutralizing liquid are mixed in the mixing tank 10.

[0024] The bottom of the mixing tank 10 is connected to the mixing pipe 8, and the free end of the mixing pipe 8 is connected to the condenser 9, as follows. Figure 1 and Figure 4 As shown, the mixing pipe 8 is bent, specifically in an S-shape or an arch shape, and its end near the mixing tank 10 is connected to the bottom of the connecting cover 11. Specifically, the top of the connecting cover 11 is detachably connected to the bottom of the mixing tank 10, that is, the edge of the connecting cover 11 is connected to the edge of the mixing tank 10 by bolts.

[0025] Furthermore, the top of the mixing tank 10 is detachably equipped with a sealing cover 7, specifically, the edge of the sealing cover 7 is fastened to the edge of the mixing tank 10 by bolts. The top of the sealing cover 7 is equipped with a motor 6, and the rotating shaft of the motor 6 is equipped with a stirring shaft 17. The stirring shaft 17 is located inside the mixing tank 10 and is equipped with multiple sets of stirring blades. Atomizing nozzles 18 and blowing heads 19 are distributed on both sides of the stirring shaft 17. When the acidic gas and the atomized neutralizing liquid can be flushed together, the mist can be further mixed by the stirring blades. Then the mixed gas travels along the mixing pipe 8. Since the mixing pipe 8 has a certain length, the atomized neutralizing liquid and the acidic gas can be further mixed during the process of the gas traveling along the mixing pipe 8.

[0026] Since both the gas and the neutralizing liquid entering the mixing tank 10 are at high temperatures, the molecular motion speed also increases, allowing the acidic substances in the gas to come into full contact with the atomized neutralizing liquid. After passing through the mixing pipe 8, they are fully mixed. The gas in the mixing pipe 8 is then liquefied and condensed by the condenser 9, and the neutralizing liquid can be collected.

[0027] Furthermore, such as Figure 1 and Figure 4 As shown, the mixing tank 10 has an inwardly recessed U-shaped groove on its lower side, which allows the mixing tank 10 to form a shape that is narrow in the middle and wide at both ends. This structure is similar to a "Venturi" mixer. Therefore, when the gas-liquid mixture passes through the narrow part of the mixing tank 10 and then enters the wide part, its volume will expand rapidly, thereby increasing the degree of gas turbulence.

[0028] Furthermore, the heating device includes a heating element 20 installed on the preheating pipe 5. The heating element 20 is an electric heating element, such as a heating rod, heating wire, or heating ceramic. The heating element 20 is located inside the insulation shell 4. The insulation shell 4 is divided into two halves. When the insulation shell 4 is closed, the insulation shell 4 encloses the heating element 20, allowing the heat emitted by the heating element 20 to directly contact the preheating pipe 5. The insulation shell 4 is specifically made of refractory materials such as ceramic shell or steel shell. Insulation layers, such as insulation cotton, heat insulation bricks, aerogel boards, etc., are provided on both the inner and outer walls of the insulation shell 4.

[0029] The two halves of the insulation shell 4 are detachably connected, and the edges of the two halves of the insulation shell 4 are specifically fastened with bolts. Figure 1 As shown, one half of the thermal insulation shell 4 is mounted on the mounting plate 3, and both ends of the mounting plate 3 are mounted on the base 1 via the first bracket 2.

[0030] Based on the above embodiments, the sides of the mixing pipe 8 and the connecting cover 11 are respectively provided with connecting brackets 13. The ends of the connecting brackets 13 are detachably installed on the second bracket 12. Specifically, the two are fastened by bolts. The bottom of the second bracket 12 is installed on the base 1, so that the mixing pipe 8 and the connecting cover 11 can be supported.

[0031] Based on the above embodiments, since the gas-liquid mixture in the mixing pipe 8 may contain a small amount of liquid at the edge of the temperature range, at least one guide pipe 14 is connected to the bottom of the mixing pipe 8. The other end of the guide pipe 14 is connected to the liquid collection tank 16, which is connected to the liquid pump 15 via a conduit. The liquid formed by liquefaction in the mixing pipe 8 flows into the liquid collection tank 16 along the guide pipe 14. When the liquid in the liquid collection tank 16 reaches a certain amount, the liquid can be pumped to a neutralization liquid storage location, such as a storage pool or storage tank, by the liquid pump 15. It should be noted that the liquid collected by the condenser 9 is also pumped to the liquid storage location for storage. The liquid collection tank 16, the liquid pump 15, and the condenser 9 are also installed on the base 1.

[0032] Based on the above embodiments, it should be noted that the preheating pipe 5 can be bent, which can increase the flow time of gas and neutralizing liquid in the pipe.

[0033] Based on the above embodiments, it should be noted that the mixing pipe 8 is provided with an insulation layer, such as insulation cotton or other materials.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
