[0002] In the field of material chemical component detection, with the continuous progress of science and technology and the increasing complexity of industrial production, accurate analysis of material components becomes increasingly important. However, various harmful gases are inevitably produced during the detection process, and if these harmful gases are not properly treated, they will not only cause serious pollution to the detection environment and threaten the health of the operating personnel, but also affect the accuracy of the detection results.

[0003] The existing harmful gas collection equipment cannot efficiently remove impurities in harmful gas after collection, and large particle impurities in the gas cannot be effectively separated from the gas flow and continue to enter the subsequent processing link with the gas flow, which not only causes wear and tear to the subsequent gas separation equipment, reduces the service life of the equipment, but also may cause impurities to mix with the target harmful gas, affecting the accuracy of gas separation; secondly, in the gas separation link, the existing gas separation equipment cannot accurately separate different harmful gases according to their physical or chemical properties, so that the purity of the separated gas is not high, which is difficult to meet the requirements of subsequent in-depth analysis and processing of specific harmful gases, in addition, the existing gas separation equipment is usually fixed and integrated, and cannot be quickly replaced to adapt to the separation of different types of harmful gases according to the detection requirements, which seriously affects the efficiency and quality of the detection work. SUMMARY

[0005] In order to achieve the above-mentioned utility model purposes, the utility model adopts the following technical scheme:

[0006] A harmful gas separation and storage structure for material chemical component detection, comprising: an impurity separator, a connecting pipe provided at the gas inlet end of the impurity separator, and a storage tank connected with the gas outlet end of the impurity separator; the gas outlet end of the impurity separator is movably connected with the storage tank through a gas separator, and the gas separator is used for separating the detected gas.

[0007] Further, one end of the connecting pipe is provided with a fan, and the input end of the fan is communicated with the collecting cover.

[0008] Further, the bottom end of the impurity separator is connected with the dust collecting tank, and a second electromagnetic valve is arranged at the connection position of the dust collecting tank and the impurity separator.

[0009] Furthermore, the impurity separator includes: a cylindrical body and a cone connected to the cylindrical body; a spiral air inlet is opened on one side of the cylindrical body, and the spiral air inlet is connected to the connecting pipe; an air guide pipe is provided through the cylindrical body, and multiple sets of guide plates are provided on the inner wall; the bottom end of the cone is connected to the dust collection tank.

[0010] Furthermore, the gas separator includes: a pipeline body and a gas separation membrane installed on the inner wall of the pipeline body; one end of the pipeline body is connected to the gas guide pipe through a connector, and the other end is connected to the storage tank through a first solenoid valve.

[0011] Furthermore, the storage tank is made of transparent material, and a pressure gauge is provided on one working surface.

[0012] Furthermore, the air guide tube is 2 / 3 of the working dimension of the cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (I) This utility model, through the setting of a collection hood, a fan, connecting pipes and an impurity separator, can actively and efficiently collect harmful gases generated during the chemical composition detection of materials, and introduce them into the cylinder in a spiral manner. Utilizing centrifugal force, large particles of impurities are thrown against the inner wall of the cylinder and slide down the inner wall to the bottom of the cone, eventually entering the dust collection tank.

Identical components are represented by the same reference numerals.

[0023] like Figures 1-3 As shown, this embodiment provides a hazardous gas separation and storage structure for material chemical composition detection, including: an impurity separator 1, a connecting pipe 2 disposed at the inlet end of the impurity separator 1, and a storage tank 7 connected to the outlet end of the impurity separator 1; the impurity separator 1 can effectively separate various impurities mixed in the hazardous gas, preventing these impurities from entering the subsequent gas separation and storage stages, thereby avoiding damage to related equipment, and improving the purity of the finally stored gas, laying the foundation for subsequent accurate analysis and treatment of hazardous gases; the outlet end of the impurity separator 1 is connected to the storage tank 7 via a gas separator 5. The gas separator 5 is threadedly connected to the storage tank 7, and a sealing ring is provided at the connection. The gas separator 5 is used to separate the detected gas. It can accurately separate the mixed gas after impurity separation based on the unique physical or chemical properties of different gases, providing high-purity samples for subsequent in-depth research and treatment of harmful gases. One end of the connecting pipe 2 is equipped with a fan 4, and the input end of the fan 4 is connected to the collection hood 3. The fan 4 can provide strong suction. During operation, the fan 4 can actively and efficiently draw harmful gases quickly through the collection hood 3 into the connecting pipe 2, improving the collection efficiency of harmful gases.

[0024] like Figure 4As shown, the bottom end of the impurity separator 1 is connected to the dust collection tank 10. A second solenoid valve 11 is provided at the connection between the dust collection tank 10 and the impurity separator 1. The second solenoid valve 11 can control the opening and closing state of the dust collection tank 10. Specifically, the impurity separator 1 includes: a cylinder 101 and a cone 103 connected to the cylinder 101. A spiral air inlet 104 is opened on one side of the cylinder 101. The spiral air inlet 104 is connected to the connecting pipe 2. When harmful gas enters the spiral air inlet 104 through the connecting pipe 2, the harmful gas will enter the cylinder 101 in a spiral trajectory. Large particles of impurities in the harmful gas are thrown towards the inner wall of the cylinder due to centrifugal force. As the gas continues to rotate and flow, these impurities gradually slide down the inner wall of the cylinder 101 to the dust collection tank 10. A gas guide pipe 102 is provided through the cylinder 101, and multiple sets of guide plates 105 are provided on the inner wall. The gas guide pipe 102 is 2 / 3 of the working size of the cylinder 101. The gas guide pipe 102 ensures that the harmful gas has enough space in the cylinder 101 for centrifugal separation of impurities, and also ensures that the gas after impurity separation can smoothly enter the gas separator 5 through the gas guide pipe 102. The bottom end of the cone 103 is connected to the dust collection tank 10.

[0025] like Figure 5 As shown, the gas separator 5 includes: a pipe body 501 and a gas separation membrane 502 installed on the inner wall of the pipe body 501; one end of the pipe body 501 is connected to the gas guide pipe 102 through a connector 6, and the other end is connected to the storage tank 7 through a first solenoid valve 8; the gas separation membrane 502 performs fine identification and separation of mixed gases based on the unique physical or chemical properties of different gases; different types of gases will pass through the gas separation membrane 502 at different rates due to differences in their molecular size, chemical affinity, and other properties, thereby achieving precise separation of the target harmful gas from other gases; and the gas separation membrane 502 is existing technology and will not be described in detail here; the storage tank 7 is made of transparent material, and a pressure gauge 9 is provided on one working surface. The pressure gauge 9 can accurately display the pressure value of the gas in the storage tank 7 in real time. The operator can adjust the gas collection and storage process in a timely manner by observing the changes in the pressure gauge 9 to prevent safety accidents caused by excessive pressure and ensure the safe and stable operation of the entire harmful gas separation and storage process.

[0026] Working principle: When collecting target harmful gases, the operator replaces the corresponding gas separation membrane 502 according to the properties of the target harmful gases. Then, one end of the gas separator 5 is connected to the impurity separator 1 through the connector 6, and the other end is threaded to the storage tank 7. Then, the fan 4 is started. The fan 4 draws the harmful gas into the connecting pipe 2 through the collection hood 3. The harmful gas enters the impurity separator 1 through the connecting pipe 2. The impurities in the harmful gas fall into the dust collection tank 10 through centrifugal force. The impurity-removed gas enters the gas separation membrane 502 in the gas separator 5 through the gas guide pipe 102. The gas separation membrane 502 filters the target harmful gas and collects it into the storage tank 7. During this process, when the pressure gauge 9 reaches the critical value, the operator closes the first solenoid valve 8 and removes the storage tank 7.
