This method has low absorption efficiency, wastes a large amount of water resources, and the concentration of hydrogen fluoride in the absorption liquid is low, increasing the pressure of subsequent treatment. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a hydrogen fluoride absorption device, which solves the problem that the single use of the spray method to absorb hydrogen fluoride easily causes waste of water resources.

[0005] To achieve the above object, the utility model provides the following technical solution: a hydrogen fluoride absorption device, including an absorption chamber, one end of the absorption chamber is provided with a conveying pipeline for conveying hydrogen fluoride into the absorption chamber, one end of the absorption chamber is connected with an output pipeline, and a feeding channel for inputting or outputting hydrogen fluoride in the absorption chamber is established between the conveying pipeline and the output pipeline. A terminal absorption member for absorbing the overflowing hydrogen fluoride is connected to the output pipeline;

[0006] The absorption chamber includes a chamber body and an internal liquid disposed inside the chamber body for absorbing hydrogen fluoride. A top cover for reducing the overflow of hydrogen fluoride to be absorbed is covered on the top of the chamber body.

[0022] The following will be combined with the drawings and embodiments to detail the implementation manner of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.

[0024] Figures 1 - 4 For an embodiment of the present utility model, the specific problem targeted by this specific embodiment is as follows: Most existing hydrogen fluoride absorption devices use spray devices, and the absorption liquid sprays the incoming hydrogen fluoride from the top of the tower. This method has low absorption efficiency, wastes a large amount of water resources, and the hydrogen fluoride concentration in the absorption liquid is relatively low, increasing the pressure of subsequent treatment. Based on the above-mentioned existing problems, this solution proposes a hydrogen fluoride absorption device. When hydrogen fluoride enters this absorption device, the absorption chamber 1 is first used for import absorption, maximizing the contact between hydrogen fluoride and the built-in liquid 12, thereby increasing the dissolution degree of hydrogen fluoride in the built-in liquid 12. On the other hand, when part of the hydrogen fluoride still overflows from the liquid surface of the built-in liquid 12, an end absorption member 5 for absorbing the overflowing hydrogen fluoride is provided to absorb hydrogen fluoride step by step, reducing the intervention amount of water resources, and thus enhancing the hydrogen fluoride stock in the unit water body.

[0025] A hydrogen fluoride absorption device is specifically provided with an absorption chamber 1. One end of the absorption chamber 1 is equipped with a conveying pipeline 2 for conveying hydrogen fluoride into the absorption chamber 1. One end of the absorption chamber 1 is connected to an output pipeline 3. The conveying pipeline 2 and the output pipeline 3 establish a material passing channel 4 for the input or output of hydrogen fluoride in the absorption chamber 1. After hydrogen fluoride enters from the conveying pipeline 2, it is absorbed by the built-in liquid 12 placed in the absorption chamber 1, and then overflows outwards through the output pipeline 3. An end absorption member 5 for absorbing the overflowing hydrogen fluoride is connected to the output pipeline 3, and the overflowing hydrogen fluoride is introduced into the end absorption member 5 through the output pipeline 3 for secondary absorption.

[0026] In the specifically described embodiment, the absorption chamber 1 includes a chamber body 11 and an internal liquid 12 disposed inside the chamber body 11 for absorbing hydrogen fluoride. The internal liquid 12 refers to a liquid that can absorb hydrogen fluoride. When in specific use, distilled water or natural water received from the urban pipe network can be filled in the chamber body 11. A top cover 13 for reducing the overflow of hydrogen fluoride to be absorbed is provided over the top of the chamber body 11. An output pipe 3 penetrates through the center of the top cover 13 and communicates with the inside of the chamber body 11. A regulating valve and an external air pump for conveying the overflowing hydrogen fluoride to the shunt pipe 51 are connected to the output pipe 3. A barometer for measuring the internal air pressure is installed on the chamber body 11. When the pressure value inside the chamber body 11 reaches a preset value, the regulating valve opens and drives the controller to control the air pump to be energized to extract the overflowing hydrogen fluoride into the output pipe 3. The liquid level of the internal liquid 12 is higher than the installation height of the conveying pipe 2 but lower than the installation height of the output pipe 3. The conveying pipe 2 is installed below the midline of the chamber body 11. A plurality of the conveying pipes 2 are provided at one end of the chamber body 11. The conveying pipe 2 includes a fixing sleeve installed on the chamber body 11 and a pipe body extending into the chamber body 11 through the fixing sleeve. A check valve for preventing the backflow of the internal liquid 12 is installed on the pipe body. Thus, after the hydrogen fluoride enters the chamber body 11, the hydrogen fluoride diffuses into the internal liquid 12, maximizing the contact between the hydrogen fluoride and the internal liquid 12, and thereby increasing the dissolution degree of the hydrogen fluoride in the internal liquid 12.

[0027] The end absorption member 5 includes a shunt pipe 51 sleeved on the output pipe 3. Two symmetrically arranged conduits 52 are connected to the shunt pipe 51. A treatment tank 53 for absorbing the shunted hydrogen fluoride is connected to any one of the conduits 52. A diversion bridge 54 is connected between the two treatment tanks 53. The diversion bridge 54 is specifically a hollow pipe body, and the hydrogen fluoride flows between the two treatment tanks 53 inside it. The installation height of the diversion bridge 54 on the treatment tank 53 is higher than the docking height of the conduit 52 and the treatment tank 53. A cavity is formed inside the treatment tank 53. An inlet and an air flow guide port are provided on the tank body. The conduit 52 is connected to the inlet, and the diversion bridge 54 is connected to the air flow guide port. A spray head 55 for spraying water into the cavity is installed on the top plate of the tank body. A nozzle 56 for spraying water into the air flow guide port is provided inside a single treatment tank 53. The shunt pipe 51 shunts the overflowing hydrogen fluoride in two directions, reducing the inventory of hydrogen fluoride in a single treatment tank 53. Thus, the internal liquid 12 in the treatment tank 53 is used to further absorb the hydrogen fluoride, and a diversion bridge 54 is provided in the two treatment tanks 53 to facilitate the flow of the overflowing hydrogen fluoride between the two treatment tanks 53, increasing the treatment speed.

The provision of power also belongs to the common knowledge in the art. And the present invention mainly protects mechanical devices, so the control mode and circuit connection of the present invention will not be further explained.
