Description

Technical Field

[0001] The present invention relates to the technical field of condensate recovery, and specifically to a device and method for recycling the condensate after the steam for dyeing is cooled down. Background Art

[0002] Dyeing and finishing factories are traditional processing factories with high consumption and high wastewater discharge. Due to the increase in production capacity and requirements, the amount of water and steam required for daily production has doubled, which also increases the burden of sewage treatment. In the face of increasingly severe environmental governance and water and discharge restrictions, therefore, it is urgent for the dyeing and finishing industry to rationally utilize water resources and save energy and reduce emissions. According to the dyeing temperature-raising principle of overflow dyeing machines, steam passes through heating tubes and indirectly contacts the dye solution in the dye vat. As the temperature changes, the dye solution reaches the required dyeing temperature within a certain period of time, achieving the effect of dyeing and coloring. Since it is steam heating during processing, during the process of heating the dye solution, the hot steam cools and condenses into hot water, which is continuously discharged outside the machine through the steam trap of the machine. In the past, the condensate generated during dyeing processing was directly discharged into the sewer and then concentrated into the sewage tank. This is also a relatively large amount of water resources. This water source is relatively clean. Currently, most factories discharge this part of the water in vain, which is really a great waste and also increases the load of sewage treatment.

[0003] Therefore, there is an urgent need to design a device and method for recycling the condensate after the steam for dyeing is cooled down to solve the above problems. Summary of the Invention

An inlet valve is installed on one side at the bottom of the air-operated pump. An outlet valve is installed on the other side at the bottom of the air-operated pump. A water collection tank is installed on the top of the tank cover behind the air-operated pump. A coiled heat exchange tube is installed inside the water collection tank. A regular exhaust valve is installed at the center of the top of the water collection tank, and the top of the regular exhaust valve is connected to the air supply pipe through a pipe fitting. A high-pressure valve is installed on one side of the top of the water collection tank. A chemical dosing tank is installed on the top of the tank cover of the second water tank. A pressure sensor is installed at the outer bottom of the chemical dosing tank through an angle piece. A support leg rod is installed at the bottom of the pressure sensor. An air pump is installed on the top of the tank cover near the air-operated pump through a mounting seat. An air delivery valve is installed on one side of the air pump. A circulation pump is installed on one side of the top of the tank cover of the second water tank. The input end of the circulation pump is provided with a pump head extending into the first water tank.

[0006] Preferably, a pressure relief valve is installed on one side of the top of the tank cover of the second water tank, and a control box is installed on one side of the top of the tank cover of the third water tank.

[0007] Preferably, an exhaust pipe is installed on one side of the top of the air-operated pump, and the exhaust pipe is connected to the regular exhaust valve. A high-pressure gas valve pipe is installed on the side of the top of the air-operated pump away from the exhaust pipe, and the high-pressure gas valve pipe is respectively connected to the high-pressure valve and the air delivery valve through a pipe fitting.

[0008] Preferably, a condensed water inlet valve is installed on the side of the top of the water collection tank away from the high-pressure valve, a cold water valve is installed at one end of the heat exchange tube, and a hot water valve is installed at the other end of the heat exchange tube.

[0009] Preferably, an air intake filter disc is installed on the back of the air pump, and a mounting seat is installed on the outer side at the bottom of the air pump.

[0010] Preferably, a feed valve is installed on one side of the top of the chemical dosing tank, a protective cover is installed on the top of the chemical dosing tank, a reversing gear disc is installed on one side inside the protective cover, a stirring paddle extending into the chemical dosing tank is installed at the bottom of the reversing gear disc, a motor is installed on one side of the protective cover, and the output end of the motor is connected to the reversing gear disc through a transmission rod.

[0011] Preferably, a connecting pipe is installed at the bottom of the first water tank, the second water tank and the third water tank through a control valve.

[0012] A method for recycling the condensed water after the cooling of the steam for dyeing, characterized in that the using steps are as follows:

[0013] Step 1: First, the steam condensate enters the inside of the water collection tank through the condensate inlet valve. Cold water is injected into the inside of the heat exchange tubes through the cold water valve. The condensate containing the steam heat inside the water collection tank can conduct heat exchange with the cold water inside the heat exchange tubes, enabling the water source inside the heat exchange tubes to obtain heat. The water source containing heat can be directly used after being output through the hot water valve, thereby saving the steam and hot water used for dyeing and saving the steam consumed normally for dyeing. Moreover, since the heating time of the steam for dyeing is shortened, the steam heating cost can be saved. Desizing and cloth washing require heating;

[0014] Step 2: The air pump is powered on to operate to generate high-pressure gas. The air supply valve is opened, and the high-pressure gas is transported to the inside of the pneumatic pump or the water collection tank through the high-pressure gas valve pipe. The corresponding air valve is opened for pressurization according to the air pressure conditions inside the pneumatic pump and the water collection tank. The pneumatic pump or the water collection tank under high pressure is convenient for water source transportation. When the air pressure inside the pneumatic pump and the water collection tank reaches the safety value, the regular exhaust valve is opened to relieve the pressure inside the pneumatic pump and the water collection tank. The relieved gas enters the inside of the aeration pipe through the pipe fittings, and the relieved gas is evenly ejected through the aeration pipe, thereby forming an aeration effect, enabling the water source inside the second water tank to be evenly mixed with the water softener, ensuring the water softening effect and efficiency of the water source inside the second water tank;

[0015] Step 3: The steam condensate inside the water collection tank is transported to the inside of the pneumatic pump through the water inlet valve. The pneumatic pump transports the steam condensate to the inside of the first water tank for precipitation through the water outlet valve. The water level inside the first water tank can be monitored in real time through the level gauge, and the monitored electrical signal is transmitted to the control box. The control box controls the operation of the circulation pump. The circulation pump is powered on to pump the precipitated water to the second water tank through the pump head, and the water level inside the second water tank is monitored in real time through the level gauge. When the water level inside the second water tank reaches the set value of the control box, the circulation pump stops transporting the water source, ensuring that the water volume inside the second water tank is at the set value, facilitating the staff to accurately proportion the water softener according to the water volume. When adding the water softener, the control box opens the feeding valve. The water softener inside the dosing tank falls into the inside of the second water tank through the feeding valve, and the weight of the water softener inside the dosing tank can be monitored in real time through the pressure sensor, and the monitored electrical signal is transmitted to the control box. The control box controls the dosing amount of the water softener according to the change in the weight of the water softener inside the dosing tank, ensuring the accuracy of the water softener dosing and the water softening effect of the water source inside the second water tank. The softened water is transported to the inside of the connecting pipe through the control valve at the bottom of the second water tank. Opening the control valve at the bottom of the corresponding third water tank can transport the water source inside the second water tank to the inside of the third water tank for storage, and the water source inside the third water tank can be supplied for use on the desizing machine and the washing machine.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The condensate recovery and utilization device and method for the steam used in dyeing inject cold water into the interior of the heat exchange tube 601 through the cold water valve 602. The condensate containing the steam heat in the water collection tank 6 can conduct heat exchange with the cold water inside the heat exchange tube 601, enabling the water source inside the heat exchange tube 601 to obtain heat, achieving the purpose of heat recovery of the device. Moreover, the water source containing heat can be directly used after being output through the hot water valve 603, thereby saving the hot water of the steam used in dyeing and the steam consumed normally in dyeing. Also, since the heating time of the steam used in dyeing is shortened, the steam heating cost can be saved, and the desizing and cloth washing require heating up.

[0018] 2. The condensate recovery and utilization device and method for the steam used in dyeing can relieve the pressure of the pneumatic pump 5 and the water collection tank 6 by opening the regular exhaust valve 605. The relieved gas enters the interior of the aeration pipe 201 through the pipe fittings, and the relieved gas is evenly ejected through the aeration pipe 201, thus forming an aeration effect, enabling the water source in the second water tank 2 to be evenly mixed with the water softener, ensuring the softening effect and efficiency of the water source in the second water tank 2, and eliminating the need for an additional power device for stirring and mixing, thereby saving the energy consumption of the power device, improving the energy conservation and emission reduction performance of the device, and enhancing the energy conservation and environmental protection of the device.

[0019] 3. The condensate recovery and utilization device and method for the steam used in dyeing can monitor the weight of the water softener in the chemical dosing tank 8 in real time through the pressure sensor 802, and transmit the monitored electrical signal to the control box 403. The control box 403 controls the dosing amount of the water softener according to the change in the weight of the water softener in the chemical dosing tank 8, ensuring the accuracy of the water softener dosing and the softening effect of the water source in the second water tank 2. The softened water is transported to the connecting pipe 9 through the control valve 901 at the bottom of the second water tank 2. Opening the control valve 901 at the bottom of the corresponding third water tank 3 can transport the water source in the second water tank 2 to the interior of the third water tank 3 for storage. The water source in the third water tank 3 can be supplied for use on the desizing machine and the washing machine. Currently, about 1200 tons of hot water can be recovered every day. By recycling this part of the hot water, not only can more than 36,000 tons of hot water be saved every month, saving 1 / 6 of the steam consumed normally (the desizing and cloth washing require heating up), but also since the heating time is shortened, it is equivalent to having 2 - 2.5 more production days per month, that is, the monthly output can be increased by 5%, and at the same time, the load of sewage treatment is reduced.

A regular exhaust valve 605 is installed at the center of the top of the water collection tank 6, and the top of the regular exhaust valve 605 is connected to the air supply pipe 201 through a pipe fitting. A high-pressure valve 606 is installed on one side of the top of the water collection tank 6. A chemical dosing tank 8 is installed on the top of the tank cover 4 of the second water tank 2. A pressure sensor 802 is installed at the outer bottom of the chemical dosing tank 8 through an angle piece. A support leg rod 803 is installed at the bottom of the pressure sensor 802. An air pump 7 is installed on the top of the tank cover 4 near the pneumatic pump 5 through a mounting seat 703. An air delivery valve 702 is installed on one side of the air pump 7. A circulation pump 10 is installed on one side of the top of the tank cover 4 of the second water tank 2. A pump head 1001 extending into the first water tank 1 is installed at the input end of the circulation pump 10.

[0031] A pressure relief valve 402 is installed on one side of the top of the tank cover 4 of the second water tank 2. The air pressure inside the second water tank 2 can be monitored in real time through the pressure relief valve 402. When the air pressure inside the second water tank 2 reaches the set value, pressure relief can be carried out through the pressure relief valve 402, ensuring the stability of the air pressure inside the second water tank 2. And a control box 403 is installed on one side of the top of the tank cover 4 of the third water tank 3. The control box 403 is electrically connected to the liquid level gauge 401, the pressure relief valve 402, the pneumatic pump 5, the inlet valve 501, the outlet valve 502, the high-pressure gas valve pipe 503, the cold water valve 602, the hot water valve 603, the high-pressure valve 606, the air pump 7, the air delivery valve 702, the pressure sensor 802, the blanking valve 804, the motor 807, the feed valve 808, the control valve 901 through wires, facilitating the control of the device operation.

[0032] An exhaust pipe 504 is installed on one side of the top of the pneumatic pump 5, and the exhaust pipe 504 is connected to the regular exhaust valve 605. By connecting the regular exhaust valve 605 and the exhaust pipe 504, it is convenient to control the pressure relief of the air pressure inside the pneumatic pump 5 and the water collection tank 6. A high-pressure gas valve pipe 503 is installed on the side of the top of the pneumatic pump 5 away from the exhaust pipe 504, and the high-pressure gas valve pipe 503 is respectively connected to the high-pressure valve 606 and the air delivery valve 702 in a through manner. The air pump 7 can respectively deliver high-pressure gas into the pneumatic pump 5 and the water collection tank 6 through the high-pressure gas valve pipe 503, increasing the air pressure inside the pneumatic pump 5 and the water collection tank 6. Through the air pressure thrust, it is convenient to transport the condensed water inside the pneumatic pump 5 and the water collection tank 6.

[0033] A condensate water inlet valve 604 is installed on the top of the water collection tank 6, away from the side of the high-pressure valve 606. Steam condensate enters the interior of the water collection tank 6 through the condensate water inlet valve 604. One end of the heat exchange tube 601 is equipped with a cold water valve 602, and the other end of the heat exchange tube 601 is equipped with a hot water valve 603. Cold water is injected into the interior of the heat exchange tube 601 through the cold water valve 602. The condensate water containing steam heat inside the water collection tank 6 can exchange heat with the cold water inside the heat exchange tube 601, and the heated water source can be directly used after being output through the hot water valve 603.

[0034] An air intake filter disc 701 is installed on the back of the air pump 7. When the air pump 7 is powered on and operates, it can suck air into the interior through the air intake filter disc 701. The air passing through the air intake filter disc 701 can effectively filter dust and floating objects, ensuring the cleanliness of the inhaled air. In addition, an installation seat 703 is installed on the outer side of the bottom of the air pump 7. The air pump 7 can be firmly fixed on the top of the pool cover 4 through the installation seat 703, ensuring the stability of the installation of the air pump 7.

[0035] One side of the top of the chemical dosing tank 8 is equipped with a feed valve 808, and a protective cover 805 is installed on the top of the chemical dosing tank 8. One side inside the protective cover 805 is equipped with a reversing gear disc 806. The bottom of the reversing gear disc 806 is equipped with a stirring paddle 801 extending into the interior of the chemical dosing tank 8. One side of the protective cover 805 is equipped with a motor 807. The output end of the motor 807 is connected to the reversing gear disc 806 through a transmission rod. By opening the feed valve 808, the water softener can be transported into the interior of the chemical dosing tank 8 for storage. When the water softener is stored, the motor 807 is periodically turned on through the control box 403. The motor 807 rotates through the transmission rod to drive the reversing gear disc 806 to rotate. The rotating reversing gear disc 806 can drive the stirring paddle 801 to rotate. The rotating stirring paddle 801 can stir and disperse the water softener stored in the interior of the chemical dosing tank 8, effectively solving the problem of caking and blocking of the water softener, and at the same time avoiding the influence of caking of the water softener on the feeding efficiency.

[0036] The bottoms of the first water tank 1, the second water tank 2 and the third water tank 3 are installed with a connecting pipe 9 through a control valve 901. The first water tank 1, the second water tank 2 and the third water tank 3 can be connected through the cooperation of the control valve 901 and the connecting pipe 9, facilitating the transportation of the water sources inside the first water tank 1, the second water tank 2 and the third water tank 3. Each water tank is about 15*15*5 m3 and can store about 1000 tons of water.

[0037] A method for recycling the condensate water after the steam for dyeing is cooled has the following usage steps:

[0038] Step 1: First, steam condensed water enters the water collecting tank 6 through the condensed water inlet valve 604, and cold water is injected into the heat exchange tube 601 through the cold water valve 602. The condensed water containing steam heat in the water collecting tank 6 can exchange heat with the cold water in the heat exchange tube 601, so that the water source in the heat exchange tube 601 obtains heat. The water source containing heat is output through the hot water valve 603 and can be used directly, thereby saving steam hot water for dyeing and saving the steam normally consumed for dyeing. In addition, since the heating time of dyeing steam is shortened, the steam heating cost can be saved. Desizing and washing cloth need to be heated.

[0039] Step 2: The air pump 7 is powered on to generate high-pressure gas, and the air delivery valve 702 is opened to transport the high-pressure gas to the inside of the pneumatic pump 5 or the water collecting tank 6 through the high-pressure gas valve pipe 503. The corresponding air valve is opened to increase the pressure according to the air pressure inside the pneumatic pump 5 and the water collecting tank 6. The pneumatic pump 5 or the water collecting tank 6 under high-pressure state is convenient for water source transportation. When the air pressure inside the pneumatic pump 5 and the water collecting tank 6 reaches a safe value, the periodic exhaust valve 605 is opened to release the pressure inside the pneumatic pump 5 and the water collecting tank 6, and the pressure-relieved gas enters the inside of the aeration pipe 201 through the pipe fitting, and the pressure-relieved gas is evenly sprayed out through the aeration pipe 201, thereby forming an aeration effect, so that the water source inside the second water pool 2 is evenly mixed with the water softener, ensuring the softening effect and softening efficiency of the water source in the second water pool 2, so that it does not need to set up a separate power device for stirring and mixing, thereby saving the energy consumption of the power device, improving the energy-saving and emission-reduction performance of the device, and increasing the energy-saving and environmental protection of the device;

[0040] Step 3: The steam condensate inside the water collecting tank 6 is transported into the pneumatic pump 5 through the water inlet valve 501. The pneumatic pump 5 transports the steam condensate into the first water tank 1 through the water outlet valve 502 for sedimentation. The water level inside the first water tank 1 can be monitored in real time through the level gauge 401, and the monitored electrical signal is transmitted to the control box 403. The operation of the circulation pump 10 is controlled through the control box 403. The circulation pump 10 is energized to pump the sedimented water to the second water tank 2 through the pump head 1001, and the water level inside the second water tank 2 is monitored in real time through the level gauge 401. When the water level inside the second water tank 2 reaches the set value of the control box 403, the circulation pump 10 stops transporting water, ensuring that the water volume inside the second water tank 2 is at the set value, which is convenient for the staff to accurately proportion the water softener according to the water volume. When adding the water softener, the blanking valve 804 is opened through the control box 403. The water softener inside the dosing tank 8 falls into the second water tank 2 through the blanking valve 804, and the weight of the water softener inside the dosing tank 8 can be monitored in real time through the pressure sensor 802, and the monitored electrical signal is transmitted to the control box 403. The control box 403 controls the dosing amount of the water softener according to the change in the weight of the water softener inside the dosing tank 8, ensuring the accuracy of the water softener dosing and the softening effect of the water source inside the second water tank 2. The softened water is transported into the connecting pipe 9 through the control valve 901 at the bottom of the second water tank 2. Opening the control valve 901 at the bottom of the corresponding third water tank 3 can transport the water source inside the second water tank 2 into the third water tank 3 for storage. The water source inside the third water tank 3 can be supplied for use on the desizing machine and the washing machine. Currently, about 1200 tons of hot water can be recycled every day, and this part of the hot water is recycled. Not only can more than 36,000 tons of hot water be saved every month, saving 1 / 6 of the normal steam consumption (the desizing and cloth washing require heating up), but also because the heating-up time is shortened, it is equivalent to having 2 - 2.5 more production days per month, that is, the monthly output can be increased by 5%. At the same time, the load of sewage treatment is also reduced.

A stirring paddle (801) extending into the chemical dosing tank (8) is installed at the bottom of the reversing gear disc (806). One side of the protective cover (805) is provided with a motor (807), and the output end of the motor (807) is connected to the reversing gear disc (806) through a transmission rod.

7. A condensate recovery and utilization device for the steam after cooling in dyeing, characterized in that: The bottoms of the first water tank (1), the second water tank (2) and the third water tank (3) are provided with a connecting pipe (9) through a control valve (901).

8. A method for recycling the condensed water after the steam for dyeing is cooled down, which is characterized in that: The using steps are as follows: Step 1: First, steam condensate enters the inside of the water collection tank (6) through the condensate inlet valve (604). Cold water is injected into the heat exchange tube (601) through the cold water valve (602). The condensate containing steam heat inside the water collection tank (6) can perform heat exchange on the cold water inside the heat exchange tube (601), so that the water source inside the heat exchange tube (601) obtains heat. The water source containing heat is output through the hot water valve (603) and can be directly used. Thus, the steam hot water for dyeing can be saved, the normal consumption of steam for dyeing can be saved, and since the heating time of the steam for dyeing is shortened, the steam heating cost can be saved. Desizing and cloth washing require heating up. Step 2: The air pump (7) is energized to operate to generate high-pressure gas. The air supply valve (702) is opened, and the high-pressure gas is transported to the inside of the pneumatic pump (5) or the water collection tank (6) through the high-pressure gas valve pipe (503). The corresponding air valve is opened for pressurization according to the air pressure conditions inside the pneumatic pump (5) and the water collection tank (6). The pneumatic pump (5) or the water collection tank (6) under high pressure is convenient for water source transportation. When the air pressure inside the pneumatic pump (5) and the water collection tank (6) reaches the safety value, the regular exhaust valve (605) is opened to relieve the pressure inside the pneumatic pump (5) and the water collection tank (6). The pressure-relieving gas enters the aeration pipe (201) through the pipe fittings, and the pressure-relieving gas is evenly ejected through the aeration pipe (201), thereby forming an aeration effect, so that the water source inside the second water tank (2) is evenly mixed with the water softener, ensuring the water softening effect and softening efficiency of the water source in the second water tank (2). Step 3: The steam condensate inside the water collecting tank (6) is transported into the pneumatic pump (5) through the water inlet valve (501). The pneumatic pump (5) transports the steam condensate into the first water tank (1) through the water outlet valve (502) for precipitation. The water level inside the first water tank (1) can be monitored in real time through the liquid level gauge (401), and the monitored electrical signal is transmitted to the control box (403). The circulation pump (10) is controlled to operate through the control box (403). The circulation pump (10) is energized to pump the precipitated water to the second water tank (2) through the pump head (1001), and the water level inside the second water tank (2) is monitored in real time through the liquid level gauge (401). When the water level inside the second water tank (2) reaches the set value of the control box (403), the circulation pump (10) stops transporting water, ensuring that the water volume inside the second water tank (2) is at the set value, which is convenient for the staff to accurately proportion the water softener according to the water volume. When adding the water softener, the blanking valve (804) is opened through the control box (403). The water softener inside the chemical dosing tank (8) falls into the second water tank (2) through the blanking valve (804). The weight of the water softener inside the chemical dosing tank (8) can be monitored in real time through the pressure sensor (802), and the monitored electrical signal is transmitted to the control box (403). The control box (403) controls the dosing amount of the water softener according to the change in the weight of the water softener inside the chemical dosing tank (8), ensuring the accuracy of the water softener dosing and the softening effect of the water source inside the second water tank (2). The softened water is transported into the connecting pipe (9) through the control valve (901) at the bottom of the second water tank (2). By opening the control valve (901) at the bottom of the corresponding third water tank (3), the water source inside the second water tank (2) can be transported into the third water tank (3) for storage, and the water source inside the third water tank (3) can be supplied for use on the desizing machine and the washing machine.
