Description

Technical Field

[0001] The utility model belongs to the technical field of unsymmetrical dimethylhydrazine gas-liquid separation, and specifically relates to unsymmetrical dimethylhydrazine gas-liquid separation equipment. Background Art

[0002] Unsymmetrical dimethylhydrazine, also known as 1,1-dimethylhydrazine, is a colorless, flammable liquid with the chemical formula C2H8N2. It is a liquid fuel with high specific impulse, high heat of combustion, and high density impulse. It is widely used in launch tests for missiles, satellites, spacecraft, and other applications, as well as in the main fuel of launch vehicles.

[0003] In the process of treating UDMH wastewater, UDMH gas-liquid separation equipment is required to ensure that the UDMH wastewater meets discharge requirements. However, the separated gas may contain unreacted oxygen, trace amounts of UDMH or other harmful gases. Therefore, it is necessary to install an activated carbon adsorption box at the exhaust port of the equipment to remove or reduce the content of harmful substances in the gas and ensure that the discharged gas meets environmental protection standards.

[0004] However, when the activated carbon adsorption box is not in use, harmful substances and impurities from the outside are easily adsorbed and fixed by the activated carbon plates inside the activated carbon adsorption box. The adsorption capacity of the activated carbon plates is limited. When the adsorption of the activated carbon plates reaches saturation, the adsorption effect will be greatly reduced, and the adsorbed harmful substances may even be released, causing secondary pollution. The moisture in the air will compete with the activated carbon plates for adsorption sites, thereby reducing their adsorption efficiency for UDMH gas. Utility Model Content

[0005] The purpose of this utility model is to provide a unilateral dimethylhydrazine gas-liquid separation device, which can control the sealing contact and separation of the sealing disk and the conical cover, thereby controlling the closing and opening of the connecting pipe and the discharge pipe. When closed, it can effectively block the external air and prevent the moisture and impurities in the external air from being adsorbed by the activated carbon plate, slowing down the saturation of the activated carbon plate and improving the service life and adsorption capacity of the activated carbon plate.

[0006] The technical solutions adopted in this application are as follows:

[0007] The top of the tube has a circle which is connected to the bottom of the tube, and the bottom of the tube is connected to the tube by a threaded hole, and the top of the tube is connected to the tube by a threaded hole.

[0008] Furthermore, two plug-in slots are provided on one side of the adsorption box, and detachable activated carbon plates are provided inside the plug-in slots.

[0009] Furthermore, an induced draft fan is provided on the inner wall of the connecting pipe and below the rotating shaft.

[0010] Furthermore, a first connecting rod is fixed to one end of the two rotating shafts and located outside the connecting tube, a second connecting rod is rotatably installed between one ends of the two first connecting rods, an electric push rod is rotatably installed on the outer wall of the adsorption box, and the output shaft of the electric push rod is rotatably connected to the middle part of the second connecting rod.

[0011] The technical effects achieved by this utility model are:

[0012] The utility model discloses a unilateral dimethylhydrazine gas-liquid separation device, which is provided with a sealing disk and a conical cover. The electric push rod cooperates with the second connecting rod and the first connecting rod to drive the rotating shaft to rotate, and the rotation drives the Z-shaped limit rod to rotate. The Z-shaped limit rod cooperates with the limit groove to drive the guide rod on the mounting plate to move, and the guide rod drives the sealing disk to move, thereby controlling the sealing contact and separation between the sealing disk and the conical cover, thereby controlling the closing and opening of the connecting pipe and the discharge pipe. When closed, it can effectively block the external air and prevent the moisture and impurities in the external air from being adsorbed by the activated carbon plate, slowing down the saturation of the activated carbon plate, and improving the service life and adsorption capacity of the activated carbon plate. In addition, it can also reduce the trouble of frequently replacing the activated carbon plate. When in use, it is sufficient to open the connecting pipe and the discharge pipe.
