Description

Technical Field

[0001] This utility model relates to the field of recycling and reuse devices, and in particular to a condensate recycling and reuse device. Background Technology

[0002] High-temperature steam in industrial pipelines is generally not 100% usable. During long-distance transportation or when encountering pipeline bends, U-turns, or ascents, some steam will condense into condensate. To prevent condensate from affecting steam transport, the traditional practice is to drain the condensate. However, directly discharging condensate has the following drawbacks: First, because condensate contains impurities, it can easily pollute the environment. Second, the condensate in the pipeline still has a high temperature, and direct discharge is not conducive to energy conservation. Utility Model Content

[0003] To address the shortcomings of existing condensate treatment methods that easily cause environmental pollution and heat waste, this invention proposes a condensate recycling and reuse device to reduce environmental impact and heat waste.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A condensate recovery and reuse device includes a water tank, a water level detector, a controller, an inlet pipe, a valve assembly, a main water supply pipe, a main booster pump, a collection pipe, an outlet pipe, a return valve, and a return pipe. One end of the inlet pipe is connected to a condensate source, and the other end is connected to the water tank through the valve assembly. The water level detector is installed on the water tank. The controller controls the opening and closing of the valve assembly based on the water level signal from the water level detector. The water tank is connected to the collection pipe via the main water supply pipe and the main booster pump. Multiple outlet pipes are installed on the collection pipe to supply water to multiple water-using devices. The collection pipe is also connected to the water tank through a return pipe. The return valve is installed on the return pipe and is controlled by the controller. The return pipe is spirally wound around the water supply pipeline of the water-using devices.

[0005] With the above setup, the recycling and reuse device can recycle condensate water for reuse, reducing environmental pollution and the waste of water resources and energy. In addition, when the return water pipe returns water, it passes through the water supply pipeline of the water-using equipment, using the condensate water to preheat the water in the water-using equipment, further improving the energy-saving effect.

[0006] Furthermore, the recycling device also includes a base for supporting the water tank, main booster pump, and water collection pipe. The base is installed on the upper side of the water-using equipment and has a through hole. The return water pipe extends through the through hole to the lower side of the base to be wrapped around the water supply pipe of the water-using equipment.

[0007] The above settings reduce the footprint of the recycling and reuse equipment.

[0008] Furthermore, the recycling and reuse device also includes a secondary water supply pipe, a secondary booster pump, a main shut-off valve, and a secondary shut-off valve. The water tank is connected to the water collection pipe through the secondary water supply pipe and the secondary booster pump. The main shut-off valve and the secondary shut-off valve are respectively installed on the main water supply pipe and the secondary water supply pipe, and are both controlled by the controller.

[0009] With the above settings, the auxiliary booster pump can be used as a backup booster pump to prevent the recycling device from shutting down in case of a failure of the main booster pump. In addition, the auxiliary booster pump can work simultaneously with the main booster pump to further increase the output flow of condensate water and achieve better energy-saving effect.

[0010] Furthermore, the recycling and reuse device also includes expansion joints installed on the main water supply pipe and the auxiliary water supply pipe.

[0011] The above-mentioned design prevents the main and auxiliary water pipes from cracking due to thermal expansion and contraction.

[0012] Furthermore, the valve assembly includes a first manual valve and a pneumatic valve group connected in parallel to the water inlet pipe. The pneumatic valve group includes a second manual valve, an air valve, and a third manual valve arranged in series. The air valve is controlled by a controller.

[0013] The above settings facilitate the maintenance of the air valve.

[0014] Furthermore, the recycling device also includes a lifting ring that is fixedly connected to the upper side of the base edge.

[0015] The above setup facilitates the hoisting of the recycling and reuse equipment. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figures 1 to 3A condensate recovery and reuse device includes a water tank 3, a water level detector 4, a controller 5, an inlet pipe 6, a valve assembly 7, a main water supply pipe 8, a main booster pump 9, a collection pipe 10, an outlet pipe 11, a return valve 12, and a return pipe 13. One end of the inlet pipe 6 is connected to a condensate source, and the other end is connected to the water tank 3 through the valve assembly 7. The water level detector 4 is installed on the water tank 3. The controller 5 controls the opening and closing of the valve assembly 7 according to the water level signal from the water level detector 4. The water tank 3 is connected to the collection pipe 10 through the main water supply pipe 8 and the main booster pump 9. Multiple outlet pipes 11 are installed on the collection pipe 10 to supply water to multiple water-using devices. The collection pipe 10 is also connected to the water tank 3 through the return pipe 13. The return valve 12 is installed on the return pipe 13 and is controlled by the controller 5. The return pipe 13 is spirally wound around the water supply pipeline of the water-using devices.

[0022] With the above setup, the recycling device can recycle condensate for reuse, reducing environmental pollution and waste of water and energy. In addition, when the return water pipe 13 returns water, it passes through the water supply pipeline of the water-using equipment, using the condensate to preheat the water in the water-using equipment, further improving the energy-saving effect.

[0023] Specifically, one end of the inlet pipe 6 is connected to the steam output pipe of the water-using equipment. The condensate in the steam output pipe enters the water tank 3 through the inlet pipe 6 and valve assembly 7. Under the action of the main booster pump 9, the condensate in the water tank 3 enters the water collection pipe 10 through the main water supply pipe 8. The return water valve 12 is closed. The condensate in the water collection pipe 10 supplies water to multiple water-using equipment through multiple outlet pipes 11. The water-using equipment in this application is connected to the water supply pipeline, which is connected to the municipal water network. The water supply pipeline supplies water to the water-using equipment. When there is an outlet pipe 11 supplying condensate to the water-using equipment, the water supply pipeline can reduce the amount of water supplied to the water-using equipment, thereby achieving a water-saving effect. In addition, the condensate has a high temperature, and the heat is utilized after entering the water-using equipment, achieving an energy-saving effect. The water level detector 4 monitors the water level in the water tank 3 in real time. When the water level drops to 1 / 3 of the height of the water tank 3, the main booster pump 9 continues to run to prevent frequent start and stop of the main booster pump 9. The controller 5 sends an opening signal to the return water valve 12, and the main booster pump... A portion of the condensate output from pump 9 flows back to water tank 3 through return valve 12 and return pipe 13, reducing the output of condensate and preventing insufficient condensate in water tank 3. At this time, water tank 3, main booster pump 9, water collection pipe 10, and return pipe 13 form a closed loop. Under the action of main booster pump 9, condensate continuously circulates in the closed loop. During the circulation, condensate passes through the water supply pipeline of the water-using equipment, using the temperature of the condensate to continuously preheat the water in the water supply pipeline. The recycling device of this application preheats the water in the water supply pipeline during the water tank 3 replenishment period without stopping the main booster pump 9. It uses the circulation of condensate to preheat the water in the water-using equipment, preventing heat loss after the condensate is idle. When the water level reaches 3 / 4 of the height of water tank 3, controller 5 sends a closing signal to valve assembly 7 and return valve 12 to prevent the water level in water tank 3 from being too high. At this time, the condensate output from main booster pump 9 flows into the water-using equipment through water collection pipe 10 and outlet pipe 11.

[0024] As one implementation method, the recycling device also includes a base 20 for supporting the water tank 3, the main booster pump 9, and the water collection pipe 10. The base is installed on the upper side of the water-using equipment and has a through hole 19. The return water pipe 13 extends through the through hole to the lower side of the base to be wrapped around the water supply pipe of the water-using equipment.

[0025] The above settings reduce the footprint of the recycling and reuse equipment.

[0026] In another embodiment, such as Figure 4 The recycling device also includes a secondary water supply pipe 14, a secondary booster pump 15, a main shut-off valve 16 and a secondary shut-off valve 17. The water tank 3 is connected to the water collection pipe 10 through the secondary water supply pipe 14 and the secondary booster pump 15. The main shut-off valve 16 and the secondary shut-off valve 17 are respectively installed on the main water supply pipe 8 and the secondary water supply pipe 14, and are both controlled by the controller 5.

[0027] With the above settings, the auxiliary booster pump 15 can be used as a backup booster pump to prevent the recycling device from shutting down after the main booster pump 9 fails. In addition, the auxiliary booster pump 15 can work simultaneously with the main booster pump 9 to further increase the output flow of condensate water and achieve better energy-saving effect.

[0028] When the water level in water tank 3 rises to 3 / 4 of its height, controller 5 does not select to close valve assembly 7. Instead, controller 5 opens auxiliary shut-off valve 17 and auxiliary booster pump 15. Auxiliary booster pump 15 works in conjunction with main booster pump 9. Condensate in water tank 3 is discharged to water-using equipment through main shut-off valve 16, main water supply pipe 8, main booster pump 9, water collection pipe 10, and water outlet pipe 11. Simultaneously, it is discharged to water-using equipment through auxiliary shut-off valve 17, auxiliary water supply pipe 14, auxiliary booster pump 15, water collection pipe 10, and water outlet pipe 11. The water equipment discharges condensate with a larger output flow rate, preventing the water level in water tank 3 from becoming too high and maximizing heat recovery. In addition, when the main booster pump 9 malfunctions, the controller 5 shuts off the main shut-off valve 16 and the main booster pump 9 to perform maintenance on the main booster pump 9. At this time, the auxiliary booster pump 15 takes over the operation of the main booster pump 9 to continue supplying water to the water equipment, and the condensate recovery and reuse can continue without stopping. After the main booster pump 9 is restored, the controller 5 reopens the main shut-off valve 16 and the main booster pump 9.

[0029] As one implementation method, the recycling device also includes expansion joints 21 installed on the main water supply pipe 8 and the auxiliary water supply pipe 14.

[0030] The above-mentioned design prevents the main water pipe 8 and the auxiliary water pipe 14 from cracking due to thermal expansion and contraction.

[0031] In one implementation, the valve assembly 7 includes a first manual valve 71 and a pneumatic valve group connected in parallel to the water inlet pipe 6. The pneumatic valve group includes a second manual valve 72, an air valve 73 and a third manual valve 74 arranged in series. The air valve 73 is controlled by the controller 5.

[0032] The above settings facilitate the maintenance of air valve 73.

[0033] In the initial stage of the recycling device of this application, the first manual valve 71 is closed, and the second manual valve 72 and the third manual valve 74 are open. The controller 5 can control the opening and closing of the gas valve 73. When the gas valve 73 is open, the condensate in the steam output pipeline can enter the water tank 3 through the water inlet pipe 6. When the gas valve 73 is closed, the water inlet pipe 6 stops replenishing water to the water tank 3. When the gas valve 73 malfunctions, the first manual valve 71 can be manually opened and the second manual valve 72 and the third manual valve 74 can be closed. The condensate in the steam output pipeline enters the water tank 3 through the first manual valve 71 and the water inlet pipe 6. At this time, no condensate will pass through the gas valve 73, and the gas valve 73 can be repaired or replaced. After the gas valve 73 is restored, the first manual valve 71 is closed and the second manual valve 72 and the third manual valve 74 are reopened.

[0034] As one implementation method, the recycling device also includes a lifting ring 18 fixedly connected to the upper side of the base edge.

[0035] The above setup facilitates the hoisting of the recycling and reuse equipment.

[0036] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
