[0001] The utility model relates to the technical field of condensate recovery and reuse, and particularly relates to a device for recovering and reusing chemical process condensate. Background Art

[0002] In the process of chemical production, the technology of condensate recovery and reuse is of great significance for energy conservation, emission reduction and cost reduction. As a by-product in the production process, chemical process condensate contains certain thermal energy and water resources. If it can be effectively recovered and reused, the resource utilization rate can be significantly improved. However, there are many technical problems in the field of chemical process condensate recovery and reuse at present.

[0003] The impurities mixed in the condensate produced by different chemical processes are different. Some chemical process condensates may contain metal ions, such as iron ions, copper ions, etc.; some may contain organic pollutants, such as benzene, phenolic substances; and some may contain suspended particulate impurities, such as sediment, dust, etc. This requires selecting appropriate filter media according to the specific types of impurities for targeted treatment in the process of condensate recovery and reuse.

[0004] However, the traditional filtration equipment for chemical process condensate recovery and reuse has obvious defects. The types and quantities of its filter media are mostly fixed, which makes the equipment can only filter one or several specified chemical process condensates. Take a condensate wastewater recovery and reuse device proposed in a patent application with the application number CN202420847783.6 as an example. Due to the limitation of its filter media, it cannot flexibly cope with condensates with various different impurities. When facing condensates with new types of impurities or complex impurity components, this equipment with fixed filter media often fails to achieve an ideal filtration effect, resulting in unqualified quality of the recovered condensate and unable to meet the requirements of production reuse, thus affecting the efficiency and quality of the entire chemical production. Therefore, this application proposes a device for recovering and reusing chemical process condensate to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a device for recovering and reusing chemical process condensate, which can effectively solve the problems in the background art.

The water outlet pipe is fixedly inserted on the lower shell. There are two hydraulic cylinders fixedly installed on the two upper connecting ears and the two lower connecting ears. The second inserting ring is fixedly installed at the lower end of the upper shell. There are several filtering components stacked between the upper shell and the lower shell. The filtering component consists of a round pipe, a first inserting ring, a blocking net and filter materials. The first inserting ring is fixedly installed at the lower end of the round pipe. There are two blocking nets symmetrically and fixedly installed on the inner wall of the round pipe. The filter materials are filled between the two blocking nets.

[0007] Preferably, a second annular groove is opened at the upper end of the lower shell on the main body of the filtering device, and four supporting legs are symmetrically and fixedly installed on the outer wall of the lower shell.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0016] Please refer to Figure 1 、 Figure 2 as well as Figure 3 、 Figure 4 ​As shown, a chemical process condensate recovery and reuse device includes a filter body 1. The filter body 1 consists of an upper shell 3, an inlet pipe 4, an upper connecting lug 5, a lower shell 6, a lower connecting lug 7, an outlet pipe 8, a hydraulic cylinder 9, and a second insert ring 17. The inlet pipe 4 is fixedly inserted into the upper shell 3. There are two upper connecting lugs 5, which are symmetrically fixedly installed on the outer wall of the upper shell 3. The lower shell 6 is located below the upper shell 3. There are two lower connecting lugs 7, which are symmetrically fixedly installed on the outer wall of the lower shell 6. The outlet pipe 8 is fixedly inserted into the lower shell 6. There are two hydraulic cylinders 9. The filter assembly 2 is fixedly installed on two upper connecting ears 5 and two lower connecting ears 7. The second insert ring 17 is fixedly installed on the lower end of the upper housing 3. Several filter assemblies 2 are stacked on the upper housing 3 and the lower housing 6. The filter assembly 2 consists of a circular tube 11, a first insert ring 12, a baffle net 15, and filter media 16. The first insert ring 12 is fixedly installed on the lower end of the circular tube 11. There are two baffle nets 15, which are symmetrically fixedly installed on the inner wall of the circular tube 11. The filter media 16 is filled between the two baffle nets 15. When using this chemical process condensate recovery and reuse device, the steps for filtering chemical process condensate are as follows: The condensate from the chemical process is introduced into the upper housing 3 of the filter equipment body 1 through the inlet pipe 4. The condensate passes through multiple stacked filter components 2 in sequence, and after being filtered by the filter media 16, it flows out through the outlet pipe 8, completing the filtration process. The steps for flexibly selecting and combining different filter media 16 of the filter components 2 according to different chemical process condensates are as follows: First, start the hydraulic cylinder 9. The piston rod of the hydraulic cylinder 9 drives the upper housing 3 to move upward, so that the upper housing 3 is away from the lower housing 6. Then, through the handle 13 on the outer wall of the circular tube 11 of the filter component 2, the existing filter components 2 with unsuitable filter media 16 are adjusted accordingly. Next, based on the impurities in the condensate, select the appropriate filter material 16 filter assembly 2. First, insert the first insert ring 12 of the bottom filter assembly 2 into the second annular groove 18 opened at the upper end of the lower housing 6. Then, insert the first insert ring 12 of the remaining filter assemblies 2 into the first annular groove 14 opened at the lower filter assembly 2 in sequence. Finally, close the hydraulic cylinder 9 to move the upper housing 3 downward, so that the second insert ring 17 is inserted into the first annular groove 14 opened at the upper end of the round tube 11 of the top filter assembly 2. Then, the new chemical process condensate can be filtered.

[0017] Specifically, the upper end of the lower housing 6 on the main body 1 of the filter equipment has a second annular groove 18. Four support legs 10 are symmetrically fixed on the outer wall of the lower housing 6. The hydraulic cylinder 9 on the main body 1 of the filter equipment is fixedly connected to the lower connecting lug 7 by bolts. The piston rod of the hydraulic cylinder 9 is fixedly connected to the upper connecting lug 5 by bolts. Two handles 13 are symmetrically fixed on the outer wall of the round tube 11 on the filter assembly 2. The upper end of the round tube 11 has a first annular groove 14. The round tube 11 on the uppermost filter assembly 2 passes through the first annular groove 14 at its upper end. An annular groove 14 is fitted onto a second insert ring 17 fixedly installed at the lower end of the upper housing 3. The first insert ring 12 on the lowest filter assembly 2 is inserted into the second annular groove 18 opened at the upper end of the lower housing 6. The first insert rings 12 on the remaining filter assemblies 2 are inserted into the first annular grooves 14 opened on the filter assemblies 2 below them. To prevent water leakage, the first insert ring 12, the second insert ring 17, the first annular groove 14, and the second annular groove 18 are interference-fitted to form a tight connection, effectively preventing condensate from seeping out from the gaps; multiple filter assemblies 2 The filter media 16 inside are all different to better deal with the complex and diverse impurities in the condensate from chemical processes. For example, for condensate containing metal ions (such as iron ions, copper ions, etc.), ion exchange resin can be filled in some filter components 2 as filter media 16 to remove metal ions using the principle of ion exchange. For condensate containing organic pollutants (such as benzene, phenols), activated carbon is selected as filter media 16. Activated carbon has a strong adsorption capacity and can effectively adsorb organic pollutants. If the condensate contains suspended particulate impurities (such as silt, dust, etc.), materials with good filtration performance, such as quartz sand, are used as filter media 16. In this way, in actual use, filter components 2 with different filter media 16 can be flexibly combined according to the specific impurity composition of the condensate from chemical processes to achieve a more precise and efficient filtration effect, ensuring that the quality of the recovered condensate meets the standards and meets the requirements for production reuse. The baffle 15 is made of corrosion-resistant metal material, and the mesh size is smaller than the particle size of the filter media 16. It is fixed to the inner wall of the round tube 11 with bolts to prevent the filter media 16 from leaking.

[0018] Ultimately, by setting up a filter equipment body 1 consisting of an upper shell 3, an inlet pipe 4, an upper connecting ear 5, a lower shell 6, a lower connecting ear 7, an outlet pipe 8, a hydraulic cylinder 9, and a second insert ring 17, and by setting up multiple filter components 2 consisting of a round pipe 11, a first insert ring 12, a baffle net 15, and filter media 16 on the filter equipment body 1, the device can flexibly select and combine different filter media 16 filter components 2 according to the different impurities in the chemical process condensate. This makes the device more versatile. Compared with traditional filter equipment with fixed filter media 16, this device can significantly improve the filtration effect on condensate from different chemical processes, ensure that the quality of the recovered condensate meets the standards and production reuse requirements, thereby improving the efficiency and quality of the entire chemical production. Moreover, the hydraulic cylinder 9 facilitates the opening and closing operation between the upper shell 3 and the lower shell 6, making it easier to replace and maintain the filter components 2, thus improving work efficiency.

[0019] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
