Description

Technical Field

[0001] This application relates to the field of condensate collection and reuse, and in particular to a condensate collection and reuse device. Background Technology

[0002] In the fabric production and processing industry, wet heat processing steps such as dyeing, printing, washing, and drying are common processes. In these steps, the moisture evaporated from the fabric forms high-temperature steam, which is discharged through the steam outlet of the dyeing and drying equipment. The drying equipment usually accelerates the evaporation of moisture through forced ventilation. When the airflow speed is high, an entrainment effect will occur. When the steam comes into contact with the fabric surface, the shear force of the airflow may peel off tiny droplets containing dye particles from the fabric surface, forming aerosols, which are discharged with the steam. This means that the steam often carries dye particles, which are then condensed to form dye-containing condensate.

[0003] Currently, many companies use rather crude methods to treat condensate during fabric production, often directly discharging it into the environment, resulting in a huge waste of water resources, increasing the cost of obtaining fresh water, raising the overall production cost of fabric, and hindering the company's sustainable development and market competitiveness. Utility Model Content

[0004] In order to reduce water waste and environmental pollution, this application provides a condensate collection and reuse device.

[0005] This application provides a condensate collection and reuse device, which adopts the following technical solution:

[0006] A condensate collection and reuse device, comprising

[0007] The condensation collection system is used to receive steam from the steam outlet of the dyeing and drying equipment and condense the received steam to form condensate.

[0008] The multi-stage recovery tank includes a primary recovery tank, a secondary recovery tank, and a tertiary recovery tank connected in sequence, and the output end of the condensation collection system is connected to the primary recovery tank;

[0009] A water storage tank is used to store condensate.

[0010] The pumping mechanism is used to pump the condensate from the three-stage recovery tank to the storage tank.

[0011] By adopting the above technical solution, the condensation collection system receives steam from the steam outlet of the dyeing and drying equipment and condenses it into condensate, realizing the preliminary treatment and conversion of steam. The condensate is transported to the primary recovery tank, and then passes through the secondary and tertiary recovery tanks in sequence. The multi-stage recovery tanks enable the condensate to undergo graded purification treatment. The pumping mechanism pumps the purified condensate from the tertiary recovery tank to a storage tank for storage. In this way, not only is the condensate containing dye particles collected and purified efficiently, realizing the recycling and reuse of condensate and reducing the waste of water resources, but also the graded purification effect of the multi-stage recovery tanks is achieved. At the same time, the entire device has a simple structure, is easy to operate and maintain, and is suitable for large-scale promotion and application.

[0012] Optionally, the condensation collection system includes a steam guide pipe, a condenser, and a conveying pipe. One end of the steam guide pipe is connected to the steam outlet of the dyeing and drying equipment, and the end of the steam guide pipe away from the dyeing and drying equipment is connected to the input end of the condenser. The output end of the condenser is connected to the conveying pipe, and the end of the conveying pipe away from the condenser extends into the interior of the primary recovery tank.

[0013] By adopting the above technical solution, the steam guide pipe directs the steam from the steam outlet of the dyeing and drying equipment to the condenser, completing the steam collection and transmission steps. The condenser condenses the steam, converting the gaseous steam into liquid condensate, thus realizing the steam condensation step. The conveying pipe transports the condensate to the primary recovery tank, converting the steam generated by the dyeing and drying equipment into condensate and transporting it to the multi-stage recovery tank, thereby realizing the subsequent graded purification treatment of the condensate, achieving the effect of efficiently collecting dye-containing condensate, laying the foundation for the recycling and reuse of condensate, and reducing the waste of water resources.

[0014] Optionally, the steam guide pipe is arranged at an angle relative to the horizontal plane, and the inlet end near the dyeing and drying equipment is higher than the outlet end far from the dyeing and drying equipment.

[0015] By adopting the above technical solution, the condensate can automatically flow to a lower position by gravity during the steam flow process, without the need for additional power assistance, ensuring the high efficiency of condensate collection, realizing the efficient collection and purification of dye-containing condensate, and reducing water waste.

[0016] Optionally, the primary recycling tank has a primary hole, which connects to the secondary recycling tank. The secondary recycling tank has a secondary hole, which connects to the tertiary recycling tank. The horizontal height of the bottom of the inner wall of the secondary hole is lower than that of the bottom of the inner wall of the primary hole.

[0017] By adopting the above technical solution, since the horizontal height of the bottom of the inner wall of the secondary hole is lower than that of the bottom of the inner wall of the primary hole, the possibility of condensate backflow between the primary and secondary recovery tanks is reduced. This allows the condensate to flow sequentially through the primary, secondary, and tertiary recovery tanks in a predetermined direction for graded purification treatment, which is beneficial to improving the condensate purification efficiency and recycling rate.

[0018] Optionally, an inspection port is provided on the top wall of the water storage tank, and a sealing cover is provided at the inspection port.

[0019] By adopting the above technical solution, it is convenient for staff to enter the water storage tank for inspection and maintenance, and the sealing cover improves the sealing performance of the water storage tank, reducing the possibility of external debris falling into the water storage tank.

[0020] Optionally, a handle is attached to the top of the sealing cap.

[0021] By adopting the above technical solution, the handle makes it easy for the operator to lift the sealing cover, saving time and effort.

[0022] Optionally, the inner wall of the primary recovery tank is connected to an isolation plate, which is located between the output end of the condensation collection system and the primary hole, and a flow port is formed between the bottom wall of the isolation plate and the inner bottom wall of the primary recovery tank.

[0023] By adopting the above technical solution, the isolation plate is set between the output end of the condensation collection system and the primary hole, and the bottom wall of the isolation plate forms a flow port with the bottom wall of the primary recovery tank. This prevents the condensate flowing into the primary recovery tank from overflowing directly from the liquid surface to the primary hole and entering the secondary recovery tank. The condensate can only flow through the flow port. When passing through the flow port, due to the change in the flow path and the space limitation, the impurities in the condensate are more likely to sink to the bottom of the primary recovery tank due to their own gravity, thereby further improving the effect of removing impurities from the condensate.

[0024] Optionally, the isolation plate is inclined, with the bottom of the isolation plate tilted towards the direction close to the primary hole.

[0025] By adopting the above technical solution, the baffle plate is set at an angle with its bottom tilted towards the primary orifice. When condensate flows into the primary recovery tank, it flows downward along the inclined baffle plate. During this process, due to the change in water flow direction and the effect of the inclined surface, some larger impurities in the condensate will settle below the baffle plate due to inertia and gravity. Afterward, the condensate continues to flow through the flow opening formed by the baffle plate and the bottom wall of the primary recovery tank. This further slows down the water flow rate, prolongs the sedimentation time of impurities, and improves the sedimentation effect. Compared with the ordinary baffle plate setting method, this inclined setting can more effectively reduce the possibility of condensate flowing into the primary recovery tank overflowing directly from the condensate liquid surface into the secondary recovery tank, thereby reducing the possibility of impurities following into the secondary recovery tank. This significantly improves the impurity removal effect of the condensate, thereby improving the purification efficiency of the entire condensate collection and reuse device, helping to achieve efficient recycling and reuse of condensate, and reducing water waste and environmental pollution.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The condensation collection system receives steam from the steam outlet of the dyeing and drying equipment and condenses it into condensate, achieving preliminary treatment and conversion of the steam. The condensate is transported to the primary recovery tank, and then sequentially passes through the secondary and tertiary recovery tanks. The multi-stage recovery tanks enable the condensate to undergo graded purification treatment. The pumping mechanism pumps the purified condensate from the tertiary recovery tank to a storage tank for storage. In this way, not only is the condensate containing dye particles collected and purified efficiently, realizing the recycling and reuse of condensate and reducing water waste, but also the graded purification effect of the multi-stage recovery tanks is achieved. At the same time, the entire device has a simple structure, is easy to operate and maintain, and is suitable for large-scale promotion and application.

[0028] 2. The steam guide pipe directs the steam from the steam outlet of the dyeing and drying equipment to the condenser, completing the steam collection and transmission steps. The condenser condenses the steam, converting the gaseous steam into liquid condensate, thus realizing the steam condensation step. The conveying pipe transports the condensate to the primary recovery tank. The steam generated by the dyeing and drying equipment is converted into condensate and transported to the multi-stage recovery tank, thereby realizing the subsequent graded purification treatment of the condensate. This achieves the effect of efficiently collecting dye-containing condensate, laying the foundation for the recycling and reuse of condensate, while reducing the waste of water resources.

[0029] 3. Since the bottom of the secondary orifice wall is lower than the bottom of the primary orifice wall, the possibility of condensate backflow between the primary and secondary recovery tanks is reduced. This allows the condensate to flow sequentially through the primary, secondary, and tertiary recovery tanks in a predetermined direction for graded purification, which is beneficial for improving the condensate purification efficiency and recycling rate.

[0034] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0035] This application discloses a condensate collection and reuse device.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2 A condensate collection and reuse device includes a condensate collection system 1, a multi-stage recovery tank 2, a pumping mechanism 3, and a water storage tank 4. The condensate collection system 1 condenses the steam produced at the steam outlet of the dyeing and drying equipment to form condensate, and transports the condensate to the multi-stage recovery tank 2. The multi-stage recovery tank 2 includes a primary recovery tank 21, a secondary recovery tank 22, and a tertiary recovery tank 23 that are connected in sequence and arranged in a straight line. This allows the dye-containing condensate to flow through the primary recovery tank 21, the secondary recovery tank 22, and the tertiary recovery tank 23 in sequence for graded purification treatment, effectively removing pollutants from the condensate, realizing the recycling and reuse of condensate, reducing environmental pollution and water waste. The pumping mechanism 3 is used to pump the condensate from the tertiary recovery tank 23 to the water storage tank 4.

[0038] The condensation collection system 1 includes a steam guide pipe 11, a condenser 12, and a conveying pipe 13. One end of the steam guide pipe 11 is connected to the steam outlet of the dyeing and drying equipment, and the end of the steam guide pipe 11 away from the dyeing and drying equipment is connected to the input end of the condenser 12, so that the steam generated by the dyeing and drying equipment flows to the condenser 12 through the steam guide pipe 11. The steam guide pipe 11 is tubular. In this embodiment, the condenser 12 is a shell-and-tube condenser 12. The output end of the condenser 12 is connected to the conveying pipe 13. The end of the conveying pipe 13 away from the condenser 12 is the output end and is inserted into the primary recovery tank 21, so as to convey the condensate to the primary recovery tank 21.

[0039] Furthermore, to allow the condensate in the steam to flow by gravity, the steam outlet of the dyeing and drying equipment is located directly above the primary recovery tank 21 and at the end of the primary recovery tank 21 furthest from the secondary recovery tank 22. The steam guide pipe 11 is installed at an angle. Specifically, the horizontal height of the end of the steam guide pipe near the dyeing and drying equipment is higher than the horizontal height of the end of the steam guide pipe near the condenser 12, and the slope of the steam guide pipe 11 is 5° to 60°. This allows the condensate to flow automatically to a lower position by gravity during the steam flow process, without the need for additional power assistance, ensuring the high efficiency of condensate collection.

[0040] The primary recovery tank 21 has a circular primary hole 211, which connects to the secondary recovery tank 22. The secondary recovery tank 22 has a circular secondary hole 221, which connects to the tertiary recovery tank 23. The primary hole 211 is located at the top of the primary recovery tank 21, allowing impurities in the condensate to settle directly to the bottom of the primary recovery tank 21 by gravity, thus performing preliminary filtration. Similarly, the secondary hole 221 is located at the top of the secondary recovery tank 22, at the end of the secondary recovery tank 22 furthest from the primary recovery tank 21, to further settle and filter the condensate, thereby improving the condensate recovery rate.

[0041] To improve the smooth flow of condensate, the horizontal height of the output end of the delivery pipe 13 is higher than the horizontal height of the top of the inner wall of the primary hole 211, and the horizontal height of the bottom of the inner wall of the secondary hole 221 is lower than the horizontal height of the bottom of the inner wall of the primary hole 211.

[0042] The pumping mechanism 3 includes a pumping device 31, a first water pipe 32, and a second water pipe 33. The input end of the pumping device 31 is connected to the first water pipe 32. The end of the first water pipe 32 away from the pumping device 31 is inserted into the tertiary recovery tank 23, so that the first water pipe 32 is inserted into the condensate in the tertiary recovery tank 23. The length of the first water pipe 32 inserted into the tertiary recovery tank 23 can be set according to the actual situation. The pumping device 31 is connected to the tertiary recovery tank 23 through the first water pipe 32. The output end of the pumping device 31 is connected to the second water pipe 33. The end of the second water pipe 33 away from the pumping device 31 is inserted into the water storage tank 4. The pumping device 31 is connected to the water storage tank 4 through the second water pipe 33. In this embodiment, the pumping device 31 is a centrifugal pump.

[0043] Specifically, a fixing hole 41 is provided on the top wall of the water storage tank 4, and a second water pipe 33 is inserted into the fixing hole 41. The outer wall of the second water pipe 33 is interference-fitted with the hole wall of the fixing hole 41. An inspection port 42 is provided on the top wall of the water storage tank 4, and a sealing cover 5 is provided at the inspection port 42. The sealing cover 5 is used to seal the water storage tank 4, making it convenient for staff to enter the water storage tank 4 for inspection and maintenance. The sealing cover 5 can ensure the airtightness of the water storage tank 4 and reduce the possibility of external debris falling into the water storage tank 4.

[0044] The top wall of the sealing cover 5 is connected to a handle 51, which is in the shape of an inverted U. The two ends of the handle 51 are fixed to the top wall of the sealing cover 5, making it easy to open the sealing cover 5.

[0045] The implementation principle of Embodiment 1 of this application is as follows: The steam guide pipe 11 directs the steam from the steam outlet of the dyeing and drying equipment to the condenser 12. The condenser 12 condenses the steam, converting the gaseous steam into liquid condensate. The conveying pipe 13 conveys the condensate to the primary recovery tank 21. Dye particles in the condensate settle. When the condensate in the primary recovery tank 21 exceeds the horizontal height of the bottom of the inner wall of the primary hole 211, the condensate overflows through the primary hole 211 to the secondary recovery tank 22. Similarly, when the condensate in the secondary recovery tank 22 exceeds the horizontal height of the bottom of the inner wall of the secondary hole 221, the condensate overflows through the secondary hole 221 to the tertiary recovery tank 23, thus achieving multi-stage recovery. The condensate collection tank 2 enables the condensate to undergo graded purification. The operator presets the condensate height in the tertiary recovery tank 23 according to the actual situation, and the preset height is lower than the horizontal height of the bottom of the inner wall of the secondary hole 221. When the condensate in the tertiary recovery tank 23 is at the preset height, the pumping device 31 is started. The pumping device 31 pumps the purified condensate in the tertiary recovery tank 23 to the storage tank 4 through the first water pipe 32 and the second water pipe 33 for storage, realizing the recycling and reuse of condensate, reducing the waste of water resources. Moreover, through the graded purification effect of the multi-stage recovery tank 2, the entire device has a simple structure, is easy to operate and maintain, and is suitable for large-scale promotion and application.

[0046] Example 2

[0047] The difference from Embodiment 1 is that, in order to reduce the possibility that the condensate flowing into the primary recovery tank 21 may overflow directly from the condensate surface into the secondary recovery tank 22, causing impurities to follow into the secondary recovery tank 22, a baffle plate 6 is fixedly connected to the wall of the primary recovery tank 21. The baffle plate 6 is located between the output end of the conveying pipe 13 and the primary hole 211. There is a flow port between the bottom wall of the baffle plate 6 and the inner bottom wall of the primary recovery tank 21 for condensate to pass through. Furthermore, the horizontal height of the top wall of the baffle plate 6 is higher than the horizontal height of the top of the inner wall of the primary hole 211, and the horizontal height of the top wall of the baffle plate 6 is higher than the horizontal height of the output end of the conveying pipe 13, so that the condensate only passes through the flow port and flows in a U-shaped trajectory, increasing the sedimentation time of impurities and further improving the effect of removing impurities from the condensate.

[0048] Furthermore, the isolation plate 6 is inclined, and the bottom of the isolation plate 6 is inclined towards the direction close to the primary hole 211. Specifically, the distance between the top of the isolation plate 6 and the pool wall where the primary hole 211 is opened is greater than the distance between the bottom of the isolation plate 6 and the pool wall where the primary hole 211 is opened.

[0049] Similarly, the same type of isolation plate 6 can also be installed in the secondary recycling pool 22 and the tertiary recycling pool 23. The effect of the installation is the same as that of the isolation plate 6 in the primary recycling pool 21, and will not be elaborated further here.

[0050] The implementation principle of Embodiment 2 of this application is as follows: when the condensate is discharged from the conveying pipe 13 into the primary recovery tank 21, the isolation plate 6 guides the flow direction of the condensate, so that the condensate can flow from the bottom through the flow port to the secondary hole 221, which facilitates the sinking of dye particles in the condensate and improves the impurity removal effect of the condensate.

[0051] The above are all preferred embodiments of this application. These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
