Description

Technical Field

[0001] A cooling and recovery integrated device for corrosive gas-liquid mixtures belongs to the field of gas-liquid recovery equipment. Background Technology

[0002] In the industrial field, along with the production of main products, some derivatives are often produced. These derivatives often appear in the form of gas-liquid mixtures. Some are corrosive and cannot be directly discharged, while others have certain recycling value. The most common practice is to first separate the gas and liquid phases, then cool them down and process them separately. The gas phase material is generally discharged into the atmosphere after subsequent processing, while the liquid phase material with recycling value is recycled. However, the existing treatment schemes for corrosive gas-liquid mixtures have the following drawbacks: (1) The entire recycling system requires separate heat exchange devices, collection devices, and gas-liquid separation devices, which is quite complex. (2) In actual working conditions, the equipment often needs to come into contact with corrosive materials, and most of the equipment is made of metal, so its lifespan is short, resulting in increased costs. Therefore, designing a technical solution that can realize the recycling and treatment of corrosive gas-liquid mixtures and improve their service life has become an urgent problem to be solved in this field. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated cooling and recovery device for corrosive gas-liquid mixtures that integrates a gas-liquid separation chamber, a heat exchanger and a liquid collection tank into one unit, and realizes gas-liquid separation, heat exchange and liquid material collection of corrosive gas-liquid mixtures using the same equipment, thus simplifying the complexity of the system.

[0004] The technical solution adopted by this utility model to solve its technical problem is: the integrated cooling and recovery device for corrosive gas-liquid mixture includes a tank body, on which a material input end and an input end are provided. The tank body includes a heat exchange tank, a gas-liquid separation chamber is provided at the top of the heat exchange tank, and a liquid collection tank is provided at the bottom of the heat exchange tank. The gas-liquid separation chamber, the heat exchange tank, and the liquid collection tank are connected and fixed as a whole in sequence. The material input end and the input end are respectively connected to the gas-liquid separation chamber.

[0005] Preferably, the top cover is installed on the top of the heat exchange tank to form a gas-liquid separation chamber.

[0006] Preferably, a number of tubes are arranged axially inside the heat exchange tank, with the upper end of the tubes connected to the gas-liquid separation chamber and the lower end of the tubes connected to the liquid collection tank.

[0008] Preferably, the heat exchange tank has a multi-segment structure arranged along the axial direction.

[0009] Preferably, the two adjacent sections of the heat exchange tank are connected by an alternating internal and external structure.

[0010] Preferably, the gas-liquid separation chamber, heat exchange tank, and liquid collection tank are fixed together as one unit by multiple fixing bolts around the perimeter.

[0011] Preferably, a liquid phase material outlet is provided on the side of the liquid collection tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the technical solution of this application, the gas-liquid separation chamber, heat exchanger and liquid collection tank are fixed as one unit, and the gas-liquid separation, heat exchange and liquid material collection of corrosive gas-liquid mixture are realized by using the same equipment, thereby reducing the complexity of the system.

[0022] Figures 1-4This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0023] like Figures 1-3 As shown, a cooling and recovery integrated device for a corrosive gas-liquid mixture includes a tank body, which includes a heat exchange tank 4. A top cover 3 is provided on the top of the heat exchange tank 4, and a liquid collection tank 7 is provided at the bottom of the heat exchange tank 4. The top cover 3, the heat exchange tank 4, and the liquid collection tank 7 are fixed together by a number of fixing bolts 5 around the pipe body.

[0024] A material inlet 2 and a material outlet 1 are provided on the top of the top cover 3. The gas-liquid mixture enters through the material inlet 2, and after gas-liquid separation is completed in the tank, the gas phase material is output through the material outlet 1. A heat exchange medium inlet 6 is provided at the lower part of one side of the heat exchange tank 4, and a heat exchange medium outlet 10 is provided at the upper part of the other side of the heat exchange tank 4. The heat exchange medium enters through the heat exchange medium inlet 6, flows in the heat exchange tank 4, and is output through the heat exchange medium outlet 10. The separated liquid phase material convects with the heat exchange medium in the heat exchange tank 4, exchanges heat, and then enters the liquid collection tank 7 for collection.

[0025] Combination Figure 4 A number of tubes 12 are arranged axially inside the heat exchange tank 4. The upper end of the tubes 12 is flush with the upper part of the heat exchange tank 4, and the lower end of the tubes 12 is flush with the lower part of the heat exchange tank 4. The upper end of the tubes 12 is sealed with the upper end of the heat exchange tank 4, and the lower end of the tubes 12 is sealed with the upper end of the heat exchange tank 4. That is, the upper end of all the tubes 12 forms the upper end of the heat exchange tank 4, and the lower end of all the tubes 12 forms the lower end of the heat exchange tank 4.

[0026] The top cover 3 is installed on the upper end of the heat exchange tank 4 and forms a gas-liquid separation chamber 11. The material inlet 2 and the material outlet 1 mentioned above are both connected to the gas-liquid separation chamber 11.

[0027] To improve the overall corrosion resistance of the device in this application, the tank body of the heat exchanger 4 is preferably made of a corrosion-resistant non-metallic material. However, due to the large volume of the heat exchanger 4, the processing of the one-piece structure is difficult. In the technical solution of this application, the tank body of the heat exchanger 4 is designed as a multi-segment structure arranged along the axial direction, further combined with... Figure 5 The adjacent tank sections are connected by an interlocking internal and external structure and sealed by external fixing bolts 5, which reduces the processing difficulty of heat exchange tank 4.

[0028] The specific working process and working principle are as follows:

[0029] An external exhaust device is connected to the material outlet 1, creating a negative pressure inside the gas-liquid separation chamber 11. Under this negative pressure, the gas-liquid mixture enters through the material inlet 2. After entering the gas-liquid separation chamber 11, the liquid phase falls due to its own weight, while the gas phase is output through the material outlet 1 for further processing, thus completing the gas-liquid separation.

[0030] The heat exchange medium enters through the heat exchange medium inlet 6, flows within the heat exchange tank 4, and exits through the heat exchange medium outlet 10. The falling liquid material enters the tube set 12 and flows downwards along the arrangement direction of the tube set 12. During the downward flow, the liquid material convects with the heat exchange medium, exchanges heat, and then enters the collection tank 7 for collection.

[0031] After the liquid material is collected to a certain height in the collection tank 7, it is discharged through the liquid material outlet 8 located on the side of the collection tank 7. A drain port 9 is also provided at the bottom of the collection tank 7 to empty the material in the collection tank 7.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
