Description

Technical Field

[0001] This invention relates to the field of industrial gas treatment technology, specifically to a comprehensive device for industrial gas dust removal, cooling, water removal, and purification. Background Technology

[0002] In modern industrial production processes, the generation of gases is usually accompanied by dust, moisture, and other impurities. During the reuse process, this can cause corrosion and blockages in reuse equipment and pipelines, resulting in low gas utilization efficiency. Furthermore, in northern winters, moisture freezes inside the pipelines, causing dust to adhere to the pipe walls, severely impacting normal production. Cleaning is also difficult, and the cleaning costs and losses are a major pain point for enterprises.

[0003] Currently, the treatment of moisture and dust accompanying production gases typically employs methods such as separation towers, purifiers, and heat exchangers. However, firstly, these treatment methods are relatively limited in their effectiveness and require the cooperation of multiple treatment devices to address different gas production processes, resulting in complex composition and control procedures. Secondly, while current treatment equipment achieves a certain degree of gas purification, its operating costs are high and gas purification is incomplete. In view of these issues, this case was developed through in-depth research. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a comprehensive device for industrial gas dust removal, cooling, water removal, and purification, thus solving the problems in the existing background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive device for industrial gas dust removal, cooling, water removal, and purification, comprising: The gas supply pipeline is provided with a first interface and a second interface at intervals along the gas supply direction; The separator has a separation inlet and a separation outlet, with the first interface connected to the separation inlet; A condenser has a condensation inlet and a condensation outlet, wherein the condensation inlet is connected to a separation outlet and the condensation outlet is connected to a second interface; A brine assembly, connected to the condenser, provides the condensing medium to the condenser; A settling assembly, which connects the separator and the condenser, is used to receive the drainage from the separator and the condensate formed by the condenser. A water supply assembly, which is connected to the sedimentation assembly and the separator, is provided with water for the separator.

[0007] The filter includes a booster drive, a transmission device, a tilting drum, and a cleaning component; The booster drive is installed on the sedimentation pipeline, the transmission is connected to the booster drive, a separation tank is provided on the sedimentation tank, the tilting drum is rotatably installed on the separation tank, and the tilting drum has a plurality of evenly distributed filter holes. The tilting drum is connected to the transmission, and the cleaning component is provided at intervals between the tilting drum to clean the dirt on the surface of the tilting drum.

[0008] The sedimentation tank is connected to a sewage delivery pump unit.

[0009] The water supply components include a water supply pump set, a spray cooler, and water supply pipelines; The water supply pump set is connected to the spray cooler and the temporary storage tank, and the water supply pipeline is connected to the spray cooler and the separator. The water supply pump set is connected to the first cooling tower.

[0010] The brine assembly includes a cold brine tank, a hot brine tank, and a brine generator unit; The cold brine tank and the hot brine tank are connected to the condenser, and the brine unit is connected to the hot brine tank; The condenser has a condensate inlet and a condensate outlet pipe. The condensate inlet is connected to the cold brine tank via an external pump set, and the condensate outlet is connected to the hot brine tank. The brine unit is connected to the hot brine tank via an internal pump set. The cold brine tank, hot brine tank, external pump group, and condenser form an external brine circulation system to provide cooling water to the condenser. The hot brine tank, internal pump group, cold brine tank, and brine unit form an internal brine circulation system to cool the internal brine circulation system.

[0011] The integrated industrial gas dust removal, cooling, water removal, and purification device also includes a chiller unit, which is connected to the brine unit and the spray cooler to cool the inlet water and the internal circulation of the brine in the separator.

[0012] The chiller unit includes a circulating water tank, a second cooling tower, an external circulation pump set, and an internal circulation pump set. The second cooling tower is installed on the circulating water pool. The external circulation pump set is connected to the circulating water pool, and the external circulation pump set, the spray cooler, the brine unit, and the second cooling tower form an external cooling circulation. The internal circulation pump set is connected to the second cooling tower and the circulating water pool to form an internal cooling circulation.

[0013] A comprehensive industrial gas treatment process includes the following steps: Industrial gas is sequentially fed into a separator and a condenser. The separator and condenser work together to perform three functions: dust removal, cooling, and water removal of the industrial gas, and a closed-loop water circulation system is constructed. The drainage generated by the separator and condenser is fed into the settling assembly, where the settling structure and self-driven filter achieve the separation of impurities in the condensate and the circulation of clean water. The condenser is connected to the brine assembly. Through the dual-circulation temperature control of the chiller unit and the brine assembly, the condenser temperature is kept stable, and the water resources are recycled. By using pipe insulation, centralized drainage, and settling components for protection, the system can be made to operate stably in the low-temperature environment of northern winters.

[0014] The wastewater external pump unit on the sedimentation assembly periodically discharges the settled impurities and sludge.

[0015] Beneficial effects This invention provides an integrated device for industrial gas dust removal, cooling, dehydration, and purification. It offers the following advantages: This integrated industrial gas treatment device achieves efficient dust removal, cooling, and dehydration of industrial gases through a two-stage integrated design of a separator and a condenser, simplifying the process and preventing blockages in winter; closed-loop water circulation reduces fresh water consumption and energy consumption; the self-driven filter uses water flow to complete efficient filtration and dirt removal, balancing operational economy and environmental protection, and comprehensively improving gas treatment efficiency.

[0016] 1) The industrial gas treatment process is highly integrated, requiring only two stages of equipment: a separator and a condenser to complete the entire purification process. The separator first captures solid impurities in the gas through spray sedimentation technology, while the condenser uses a stable cold brine medium provided by the brine component to condense water vapor in the gas into liquid water and allow it to settle. The two devices work together to achieve the triple functions of dust removal, cooling, and water removal, which greatly simplifies the complex pipeline structure of traditional multi-device series connection and reduces control nodes. Especially in the low-temperature environment of winter in the north, by centrally discharging condensate to the sedimentation component, the blockage of pipelines and equipment pollution caused by water vapor condensation are effectively avoided, ensuring the stable operation of the system in low-temperature scenarios.

[0017] 2) The closed-loop water circulation system significantly reduces operating costs. After the sedimentation component separates the condensate and impurities generated by the separator and condenser, the upper clear water is filtered twice by the filter and then returned to the storage tank through the backflow pipe. The water in the storage tank is pumped to the spray cooler for cooling and then used as the spray water for the separator. The water supply pipe only needs to replenish the water lost by natural evaporation, which greatly reduces the consumption of fresh water. While improving cooling efficiency, it also reduces energy consumption, achieving efficient recycling of water resources and cost optimization.

[0018] 3) The filter in the settling assembly is designed with self-driving technology at its core, which has both operational and environmental advantages. The filter uses the water flow in the settling pipeline to drive the booster drive, which drives the rotating drum and the cleaning components to work. No additional power source is required, reducing energy consumption. The rotating drum effectively traps residual impurities, and the cleaning components remove dirt from the filter screen surface in real time, avoiding clogging and extending the equipment life, reducing maintenance frequency. It also reduces wastewater discharge and environmental impact by recycling the filtered water. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7 The present invention provides an implementation scheme: In the modern industrial gas production process, the preparation of industrial gas is accompanied by a lot of water vapor and impurities, which not only causes insufficient gas purity and affects the use of gas, but also easily causes pipeline blockage and equipment pollution in the winter in the north due to the low temperature.

[0029] Currently, controlling water vapor, impurities, and temperature in industrial gases requires the cooperation of various equipment. However, there are many types of equipment, and their composition and control processes are quite complex. Furthermore, although the current treatment equipment has achieved a certain gas purification effect, its operating costs are high, and the gas purification is not thorough.

[0030] To address the aforementioned issues, this application discloses an integrated device for industrial gas dust removal, cooling, water removal, and purification, comprising: a gas supply pipeline 1, a separator 2, a condenser 3, a brine assembly 4, a sedimentation assembly 5, and a water supply assembly 6.

[0031] Gas supply line 1 is connected to the gas production equipment. The produced gas is introduced into gas supply line 1. A first interface 11 and a second interface 12 are provided at intervals along the gas supply direction. Separator 2 has a separation inlet 21 and a separation outlet 22. The first interface 11 is connected to the separation inlet 21. Condenser 3 has a condensation inlet 31 and a condensation outlet 32. The condensation inlet 31 is connected to the separation outlet 22, and the condensation outlet 32 ​​is connected to the second interface 12. Brine component 4 is connected to condenser 3 to provide condensation medium for condenser 3. Sedimentation component 5 is connected to separator 2 and condenser 3 to receive the drainage of separator 2 and the condensate formed in condenser 3. Water supply component 6 is connected to sedimentation component 5 and separator 2 to supply water to separator 2.

[0032] In this process, industrial gas flows from the first interface 11 to the second interface 12 in the gas supply pipeline 1. The first interface 11 is connected to the separation inlet 21. The industrial gas first enters the separator 2 from the first interface 11. The separator 2 is preferably a spray tower. The separator 2 sprays and settles the gas, causing impurities in the industrial gas to settle. The condenser inlet 31 of the condenser 3 is connected to the separation outlet 22, so that the industrial gas that has been purified is discharged from the separation outlet 22 into the condenser 3. The condenser 3 uses the cold brine generated by the brine component 4 as a heat exchange medium to condense and settle the water vapor contained in the industrial gas. The purified industrial gas can then be introduced into the application site. The impurities and condensate generated by the condenser 3 and the separator 2 are discharged into the settling component 5. The settling component 5 separates the condensate and impurities, thereby recycling the water resources.

[0033] In some embodiments of this application, the sedimentation assembly 5 includes a temporary storage tank 51, a sedimentation tank 52, a sedimentation pipeline 53, a filter 54, and a backflow pipe 55; the temporary storage tank 51 is connected to the water supply assembly 6, the sedimentation pipeline 53 is connected to the condenser 3 and the separator 2, and the sedimentation pipeline 53 is connected to the sedimentation tank 52, the backflow pipe 55 is connected to the temporary storage tank 51 and the sedimentation tank 52, and a filter 54 is provided between the backflow pipe 55 and the sedimentation tank 52; wherein, a water supply pipe is connected to the temporary storage tank 51, and a first cooling tower 511 is also provided on the temporary storage tank 51.

[0034] The settling tank 52 is a space for settling treatment. A settling structure 57 is installed in the settling tank 52 to facilitate the settling of the condenser 3 and the separator 2. The clean water separated by settling is filtered twice by the filter 54 and then introduced into the temporary storage tank 51 through the backflow pipe 55. The temporary storage tank 51 is then connected to the water supply component 6 to supply the separated clean water to the spray device of the separator 2, so as to achieve the purpose of water recycling. In order to meet and make up for the gap caused by water loss, a water replenishment pipe is installed on the temporary storage tank 51 to replenish the water volume and maintain the water supply stability of the separator 2. A first cooling tower 511 is also installed on the temporary storage tank 51 for internal circulation of the temporary storage tank 51 to cool the water in the temporary storage tank 51.

[0035] In some embodiments of this application, as per the appendix to the specification... Figure 4-7 It is known that the sedimentation structure 57 includes a sedimentation baffle 571, a interception baffle 572, and a buffer baffle 573. The sedimentation baffle 571, the interception baffle 572, and the buffer baffle 573 are arranged sequentially and spaced apart in the sedimentation tank 52 along the water flow direction. The sedimentation baffle 571 and the buffer baffle 573 are both located on the bottom surface of the sedimentation tank 52 and are spaced apart from the top surface of the sedimentation tank 52. The interception baffle 572 is located on the top surface of the sedimentation tank 52 and is spaced apart from the bottom surface of the sedimentation tank 52. A filter screen plate 574 is transversely connected between the interception baffle 572 and the buffer baffle 573.

[0036] The aforementioned settling tank 52 can be built adjacent to the temporary storage tank 51 to facilitate the arrangement of the backflow pipe 55. The water flowing out of the condenser 3 and the separator 2 is introduced into the settling tank 52 through the settling pipe 53. The water flows through the space between the settling baffle 571 and the top surface of the settling tank 52 and flows into one side of the intercepting baffle 572. During this process, the suspended solids have sufficient time to settle. The settling water further enters between the intercepting baffle 572 and the settling baffle 571. Since the intercepting baffle 572 is connected to the top of the settling tank 52, it can block the impurities at the top, allowing them sufficient time to settle. The continuing to flow settling water is filtered and intercepted by the buffer baffle 573 and the filter screen 574, in which the suspended solids and impurities are separated, and the water enters the buffer space between the buffer baffle 573 and the settling tank 52.

[0037] In some embodiments of this application, a sewage external pump group 5645 is connected to the sedimentation tank 52. The sewage external pump group 5645 can discharge the suspended solids and impurities settled at the bottom of the sedimentation tank 52 and clean the sedimentation tank 52 regularly to enable the sedimentation tank 52 to work for a long time.

[0038] In some embodiments of this application, the filter 54 includes a booster drive 541, a transmission device 542, a tilting drum 543, and a cleaning device 544; the booster drive 541 is installed on the sedimentation pipeline 53, the transmission device 542 is connected to the booster drive 541, a separation tank is provided on the sedimentation tank 52, the tilting drum 543 is rotatably installed on the separation tank, and the tilting drum 543 has a plurality of evenly distributed filter holes, the tilting drum 543 is connected to the transmission device 542 in a driving connection, and the cleaning device 544 is provided at intervals between the tilting drum 543 to clean the dirt on the surface of the tilting drum 543.

[0039] The filter 54 is powered by the drainage from the condenser 3 and the separator 2. Specifically, a booster drive 541 is connected to the end of the settling pipe 53. The booster drive 541 can be a multi-stage paddle with coaxial blades. When the water flows through the settling pipe 53, it directly drives the booster drive 541 to rotate. The booster drive 541 then drives the transmission 542 to move. The transmission 542 will synchronously drive the tilting drum 543 to move. The tilting drum 543 uses its evenly distributed filter holes to further filter the settling upper layer water, thereby removing residual impurities in the settling upper layer water. Then, the transmission 542 can drive the cleaning component 544 to move, synchronously sweeping away impurities attached to the outside of the tilting drum 543.

[0040] Specifically, refer to the instruction manual. Figure 4-7 It is understood that the aforementioned transmission device 542 includes a connecting seat 5421, a transmission rod 5423, a first transmission wheel set 5422, and a second transmission wheel set 5424. The connecting seat 5421 is connected to the tail end of the settling pipe 53. The inner cavity of the connecting seat 5421 provides installation space for the first transmission wheel set 5422. The first transmission wheel set 5422 is connected to the booster drive 541 and the transmission rod 5423 respectively. The booster drive 541 drives the first transmission wheel set 5422 to rotate. Composed of multiple meshing gears, it serves to steer and amplify torque. The first transmission wheel set 5422 can drive the transmission rod 5423 to rotate. The transmission rod 5423 rotates through the second transmission wheel set 5424, which is installed on one side of the tipping roller 543 and the sweeping component 544. The second transmission wheel set 5424 drives the tipping roller 543 and the sweeping component 544 to rotate, thereby causing the tipping roller 543 and the sweeping component 544 to interact and sweep away the impurities attached to the tipping roller 543.

[0041] Specifically, the filter screen holes on the aforementioned tilting roller 543 trap impurities. The tilting roller 543 is connected to the second transmission wheel set 5424. The aperture of the filter screen holes is smaller than the mesh of the filter screen plate 574. Multiple paddles are spaced apart on the outside of the tilting roller 543. These paddles can block the impurities trapped by the tilting roller 543, making cleaning convenient.

[0042] Specifically, the cleaning component 544 includes a pair of oppositely arranged rotating parts 5441 and a rotating belt 5442 arranged around the pair of rotating parts 5441. The rotating belt 5442 is simultaneously driven by the pair of rotating parts 5441 and the second transmission wheel set 5424. A cleaning strip 5443 is provided on the outside of the rotating parts 5441. The cleaning strip 5443 abuts against the outside of the turning roller 543. The cleaning strip 5443 is densely covered with cleaning bristles. Under the cleaning action of the cleaning bristles, the impurities isolated by the turning roller 543 are swept away.

[0043] In some embodiments of this application, the water supply assembly 6 includes a water supply pump set 61, a spray cooler 62, and a water supply pipeline 63; the water supply pump set 61 is connected to the spray cooler 62 and the temporary storage tank 51, and the water supply pipeline 63 is connected to the spray cooler 62 and the separator 2; wherein, the water supply pump set 61 is connected to the first cooling tower 511.

[0044] The water supply assembly 6 is powered by a water supply pump set 61. Preferably, at least two water supply pumps are installed in the water supply pump set 61 to ensure stable operation. The water supply pump set 61 draws purified water from the temporary storage tank 51 and introduces it into the spray cooler 62. The spray cooler 62 cools the purified water. The cooled water is then transported to the separator 2 through the water supply pipeline 63 for spray separation. A flow monitoring sensor is installed on the water supply pipeline 63 to monitor the flow rate of the water supply pipeline 63 and control the water supply pump set 61. The water supply pump set 61 is also connected to the first cooling tower 511. The water supply rate of the water supply pump set 61 is controlled according to the flow rate of the flow monitoring sensor. At the same time, a portion of the water can be diverted to the first cooling tower 511 so that the diverted water falls from a height and comes into contact with the air, thereby achieving cooling.

[0045] In some embodiments of this application, the brine assembly 4 includes a cold brine tank 41, a hot brine tank 42, and a brine generator 43; the cold brine tank 41 and the hot brine tank 42 are connected to the condenser 3, and the brine generator 43 is connected to the hot brine tank 42; the condenser 3 has a condensate inlet 33 and a condensate outlet 34, the condensate inlet 33 is connected to the cold brine tank 41 through an external pump group 45, the condensate outlet is connected to the hot brine tank 42, and the brine generator 43 is connected to the hot brine tank 42 through an internal pump group 44; wherein, the cold brine tank 41, the hot brine tank 42, the external pump group 45, and the condenser 3 constitute an external brine circulation to provide cooling water to the condenser 3, and the hot brine tank 42, the internal pump group 44, the cold brine tank 41, and the brine generator 43 constitute an internal brine circulation to cool the internal brine circulation.

[0046] The brine assembly 4 serves to provide cooling water to the condenser 3. The brine assembly 4 consists of a cold brine tank 41, a hot brine tank 42, and a brine compressor unit 43. The brine compressor unit 43 acts as a temperature control device. Through the internal circulation of brine formed by the brine compressor unit 43, the hot brine tank 42, and the internal pump unit 44, the brine is cooled and circulated internally. This process cools the brine in the hot brine tank 42, and the cooled brine is then introduced into the cold brine tank 41. The cold brine tank 41 serves as the cooling source for the condenser 3. The cold brine tank 41, the condenser 3, and the hot brine tank 42 are all connected. This constitutes an external brine circulation system. The cold brine tank 41 is connected to the condenser inlet 33 of the condenser 3 via an external pump group 45. Under the action of the external pump group 45, the cold brine in the cold brine tank 41 is sent into the condenser 3. In the condenser 3, the cold brine exchanges heat with the purified gas, causing the industrial gas to cool down and condense. The treated industrial gas achieves the purpose of dehydration. After heat exchange, the cold brine flows back into the hot brine tank 42. Through the internal and external dual circulation brine component 4, the cold brine is cooled down while avoiding the effects of poor condensation caused by temperature fluctuations, thus forming a closed-loop brine temperature control mechanism.

[0047] According to the instruction manual Figure 1 It is known that an integrated device for industrial gas dust removal, cooling, water removal and purification also includes a chiller unit 7, which is connected to a brine chiller unit 43 and a spray cooler 62, respectively, for cooling the water inlet and the internal circulation of brine in the separator 2.

[0048] In some embodiments of this application, the chiller unit 7 includes a circulating water tank 71, a second cooling tower 72, an external circulation pump unit 73, and an internal circulation pump unit 74; the second cooling tower 72 is installed on the circulating water tank 71, the external circulation pump unit 73 is connected to the circulating water tank 71, and the external circulation pump unit 73, together with the spray cooler 62, the brine unit 43, and the second cooling tower 72, constitutes an external cooling circulation, and the internal circulation pump unit 74 is connected to the second cooling tower 72 and the circulating water tank 71 to constitute an internal cooling circulation.

[0049] The chiller unit 7 is centered on the circulating water tank 71, and a second cooling tower 72 is installed on the circulating water tank 71. The circulating water tank 71 is connected to two sets of circulation systems, an inner and an outer one. The outer circulation system is powered by an outer circulation pump set 73, which pumps water from the circulating water tank 71 and delivers it to the brine chiller unit 43 and the spray cooler 62, respectively, providing circulating cooling water for the spray cooler 62 and the brine chiller unit 43. The circulating cooling water is mixed with the water that has passed through the spray cooler 62 and is about to enter the separator 2, as well as the hot water that has passed through the brine chiller unit 43. The brine undergoes heat exchange to lower its temperature. The heated circulating cooling water then passes through the second cooling tower 72, exchanges heat with the air, and returns to the circulating water pool 71 to achieve cooling. The internal circulation pump unit 74 draws water from the circulating water pool 71 and introduces it into the second cooling tower 72. The water falls in the second cooling tower 72 and exchanges heat with the air, thereby lowering the temperature of the water in the circulating water pool 71 and preparing for external circulation cooling. At the same time, the circulating water pool 71 simultaneously meets the cooling needs of the brine unit 43 and the spray cooler 62, and the internal and external circulations work together.

[0050] In summary, the integrated industrial gas dust removal, cooling, water removal, and purification device applying the technical solution of this application has the following beneficial effects: 1) The industrial gas treatment process is highly integrated, requiring only two stages of equipment, separator 2 and condenser 3, to complete the entire purification process. Separator 2 first captures solid impurities in the gas through spray sedimentation technology, while condenser 3 uses the stable cold brine medium provided by brine component 4 to condense water vapor in the gas into liquid water and let it settle. The two devices work together to achieve the triple functions of dust removal, cooling and water removal, which greatly simplifies the complex pipeline structure of traditional multi-device series connection and reduces control nodes. Especially in the low-temperature environment of winter in the north, by centrally discharging condensate to sedimentation component 5, the blockage of pipelines and equipment pollution caused by water vapor condensation are effectively avoided, ensuring the stable operation of the system in low-temperature scenarios.

[0051] 2) The closed-loop water circulation system significantly reduces operating costs. After the sedimentation component 5 separates the condensate and impurities generated by the separator 2 and condenser 3, the upper layer of clear water is filtered twice by the filter 54 and then returned to the storage tank 51 through the backflow pipe 55. The water in the storage tank 51 is transported to the spray cooler 62 by the water supply pump set 61 and then used as the spray water for the separator 2. The water replenishment pipe only needs to replenish the water lost by natural evaporation, which greatly reduces the consumption of fresh water. While improving cooling efficiency, it also reduces energy consumption, realizing the efficient recycling of water resources and cost optimization.

[0052] 3) The filter 54 in the settling assembly 5 is designed with self-driving technology as its core, which has both operational and environmental advantages. The filter 54 uses the water flow in the settling pipe 53 to drive the booster drive 541, which drives the rotating drum 543 and the cleaning component 544 to work. No additional power source is required, which reduces energy consumption. The rotating drum 543 effectively traps residual impurities, and works with the cleaning component 544 to remove dirt from the filter screen surface in real time, avoiding clogging and extending the equipment life, reducing maintenance frequency. It also reduces wastewater discharge and environmental impact by recycling the filtered water.

[0053] In other embodiments of this application, a comprehensive industrial gas treatment process is also disclosed, adapted to the implementation of the aforementioned comprehensive industrial gas dust removal, cooling, water removal, and purification device, comprising the following steps: Step S100: The industrial gas is sequentially introduced into the separator and the condenser. The separator and the condenser work together to perform three functions: dust removal, cooling and water removal of the industrial gas, and a closed-loop water circulation system is constructed.

[0054] Step S110: Industrial gas enters the separator through the first interface of the gas supply pipeline. Cooling water is sprayed downwards through the top spray device. When the gas flows from bottom to top, it comes into full contact with the water film. Solid impurities are captured by the water film and settle to the bottom drain, thus achieving dust removal and preliminary cooling.

[0055] Step S120: The gas processed by the separator enters the condenser through the separator outlet and exchanges heat with the -10℃ cold brine provided by the brine component in a countercurrent manner outside the tube bundle. The gas temperature drops to 10-15℃, the water vapor condenses into liquid water and is discharged into the settling component through the condensate outlet pipe. The dried gas is output to the application site through the second interface, completing the integration of dust removal, cooling and water removal functions.

[0056] Step S200: The drainage generated by the separator and condenser is fed into the settling assembly. The settling structure and the self-driven filter achieve the separation of impurities in the condensate and the circulation of clean water, and the sludge resource utilization is completed simultaneously.

[0057] Step S210: The condensate discharged from the separator and condenser enters the sedimentation tank through the sedimentation pipe, and passes through the sedimentation baffle, interception baffle, buffer baffle and filter screen in sequence to achieve the classification and sedimentation of suspended solids and separation of clear water.

[0058] Step S220: After the sedimentation supernatant water enters the separation tank, the water flow drives the booster water wheel to rotate the tilting drum. The 0.3mm filter holes on its surface trap residual impurities. The cleaning component removes the filter screen dirt in real time through the rotating brush. The clean water after secondary filtration flows back to the temporary storage tank through the backflow pipe. The sludge is discharged periodically by the sewage external pump group.

[0059] Step S300: The condenser is connected to the brine assembly. The temperature of the condenser is kept stable through the dual circulation temperature control of the chiller unit and the brine assembly, and the water resources are recycled.

[0060] Step S310: The clean water in the temporary storage tank is transported to the spray cooler by the water supply pump set and cooled to 8-12℃. It is then returned to the separator spray device through the water supply pipeline. The flow monitoring sensor adjusts the pump set speed in real time. Excess water is diverted and cooled by the first cooling tower before being replenished to the system.

[0061] Step S320: The cold brine tank continuously supplies cooling to the condenser through the external pump set. After heat exchange, the heated brine flows back to the hot brine tank, enters the brine unit through the internal pump set to cool down to -10℃, and then returns to the cold brine tank, forming an external circulation. At the same time, the brine unit and the circulating water pool achieve heat exchange through the second cooling tower to maintain a stable internal circulation temperature.

[0062] Step S400: Ensure stable system operation in the low-temperature environment of northern winter through pipeline insulation, centralized drainage and settlement component protection.

[0063] Step S410: During operation in northern winters, the condensate produced by the separator and condenser is discharged into the settling assembly. The pipes are prevented from freezing by the insulation design of the temporary storage tank and the settling tank. The sludge at the bottom of the settling tank is discharged regularly to prevent blockage.

[0064] Step S420: The first and second cooling towers achieve dual cooling through air-water heat exchange, ensuring that the temperature of the spray water and brine remains stable within the process requirements range, and avoiding increased gas flow resistance or equipment contamination caused by low temperature.
