Description

Technical Field

[0001] This utility model relates to the technical field of steam supply equipment, specifically an adjustable steam supply equipment. Background Technology

[0002] Steam supply is a process that uses steam as a heat energy carrier to stably and continuously supply steam to various steam-using equipment or processes through a specific pipeline system, equipment and control device. In the recycled resource chemical fiber processing industry, raw materials need to be dried by steam after cleaning, and steam supply equipment is used to supply steam.

[0003] For example, the authorized patent with announcement number CN206430080U (a centralized steam supply and distribution device) includes a distribution box, which is connected to a steam production device via an air inlet pipe. The steam production device is mounted on a bracket. An electrical control box is installed on one side of the distribution box, and a storage battery is installed inside the electrical control box. One end of the air inlet pipe passes through the distribution box and is connected to a first branch pipe. A first solenoid valve is installed on the air inlet pipe. Several second branch pipes are installed on the first branch pipe. A second solenoid valve, a pressure relief valve, and a steam flow meter are installed on the second branch pipes. From top to bottom, the components are the second solenoid valve, the pressure relief valve, and the steam flow meter. A third branch pipe is installed at the bottom of the second branch pipe. Several fourth branch pipes are installed on the third branch pipes. A third solenoid valve is installed on the fourth branch pipes.

[0004] While the aforementioned existing technologies facilitate steam distribution, they lack a steam regulation structure during supply. Consequently, traditional steam supply pipelines are mostly used directly for distribution within the plant, without steam moisture treatment or steam superheating treatment. This results in unstable steam quality, increased equipment corrosion, and impacts production processes and product quality. Therefore, the market urgently needs to develop an adjustable steam supply device to help solve these existing problems. Utility Model Content

The steam-water separation mechanism includes a second electric valve, a first supply pipe, a steam-water separator, and a second supply pipe. Gas pipe one and gas supply pipe two are fixedly installed on both sides of the gas-water separator. One end of gas supply pipe one is fixedly connected to electric valve two, which is fixedly installed at the rear end of the four-way pipe. One end of gas supply pipe two is fixedly connected to a direct current pipe. A water replenishment mechanism is provided at the front end of the four-way pipe. The water replenishment mechanism includes electric valve three, gas supply pipe three, a water replenishment tank, and gas supply pipe four. Gas supply pipe three and gas supply pipe four are fixedly installed on both sides of the water replenishment tank. One end of gas supply pipe three is fixedly connected to electric valve three, which is fixedly installed at the front end of the four-way pipe. One end of gas supply pipe four is fixedly connected to a direct current pipe. A temperature sensor two is fixedly installed above gas supply pipe four.

[0007] Preferably, a water supply pipe is fixedly installed above the water replenishment tank, a flow regulating valve is fixedly installed above the inside of the water replenishment tank, one end of the water supply pipe extends into the inside of the water replenishment tank and is fixedly connected to the flow regulating valve, a water distributor is fixedly installed below the flow regulating valve, and multiple atomizing nozzles are fixedly installed below the water distributor.

[0008] Preferably, the height of the third gas supply pipe is lower than that of the fourth gas supply pipe, and a distribution plate is fixedly installed inside the water supply tank, with multiple vent holes inside the distribution plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting up a steam-water separation mechanism and a water replenishment mechanism, when the steam temperature is lower than the same steam saturation temperature during steam supply, the equipment uses the steam-water separation mechanism to achieve water-steam separation and obtain dry steam, thus avoiding the corrosion caused by steam carrying water to the equipment and extending the service life of the equipment.

When the steam is replenished with water, the flow regulating valve can accurately adjust the amount of water replenished, ensuring that the ratio of condensate to steam is appropriate and avoiding the impact of too much or too little water replenishment on the steam quality. The water distributor and atomizing nozzles atomize the water evenly, increasing the contact area between water and steam, making the steam cooling process faster and more uniform, effectively reducing the steam temperature and increasing its practicality.

[0016] (3) The utility model is fixedly connected to the water tank by one end of the recovery pipe installed below the steam-water separator and the lower end of the return water pipe installed below the water tank, so that the water separated by the steam-water separator enters the water tank through the recovery pipe, and the excess water in the water tank flows back to the water tank through the return water pipe, thus realizing the recycling of water, reducing the waste of water resources, and increasing practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of an adjustable steam supply device, including an inlet pipe 1, a temperature sensor 8 fixedly installed above the inlet pipe 1, an externally connected power plant steam constant pressure supply device, a four-way pipe 2 fixedly installed on one side of the inlet pipe 1, an electric valve 3 fixedly installed on one side of the four-way pipe 2, a direct current pipe 4 fixedly installed on one side of the electric valve 3, a regulating proportional valve 5 fixedly installed on one side of the direct current pipe 4, a supply pipe 6 fixedly installed on one side of the regulating proportional valve 5, a pressure sensor 7 fixedly installed above the supply pipe 6, the pressure sensor 7 being an EJA110 pressure sensor, and a steam-water separation mechanism provided at the rear end of the four-way pipe 2. The steam-water separation mechanism includes an electric valve 9, a gas delivery pipe 10, a steam-water separator 11, and a second gas delivery pipe 12. Two 12 are fixedly installed on both sides of the gas-water separator 11. One end of the gas supply pipe 10 is fixedly connected to the electric valve 2 9. The electric valve 2 9 is fixedly installed at the rear end of the four-way pipe 2. One end of the gas supply pipe 2 12 is fixedly connected to the direct current pipe 4. The front end of the four-way pipe 2 is provided with a water replenishment mechanism, which includes an electric valve 3 13, a gas supply pipe 3 14, a water replenishment tank 15, and a gas supply pipe 4 16. The gas supply pipe 3 14 and the gas supply pipe 4 16 are fixedly installed on both sides of the water replenishment tank 15. One end of the gas supply pipe 3 14 is fixedly connected to the electric valve 3 13. The electric valve 3 13 is fixedly installed at the front end of the four-way pipe 2. One end of the gas supply pipe 4 16 is fixedly connected to the direct current pipe 4. A temperature sensor 29 is fixedly installed above the gas supply pipe 4 16. Both the temperature sensor 1 8 and the temperature sensor 29 are PT100 temperature sensors.

[0024] Steam is delivered through the inlet pipe 1, and its temperature is detected by the temperature sensor 8. When the steam temperature is lower than the equivalent steam saturation temperature, the equipment uses a steam-water separation mechanism, which opens the electric valve 9, allowing the steam to flow through the gas delivery pipe 10 to the steam-water separator 11, achieving water-water separation and obtaining dry steam. This avoids corrosion caused by water in the steam and extends the equipment's service life. When the steam temperature is higher than the equivalent steam saturation temperature, the water replenishment mechanism activates, opening the electric valve 13, allowing the steam to flow through the gas delivery pipe 14 to the water replenishment tank 15, replenishing the steam and lowering its temperature. When the steam temperature is within the steam saturation temperature range, the electric valve 3 opens, allowing the steam to flow into the direct current pipe 4, and then through the regulating proportional valve 5, finally outputting from the gas supply pipe 6. Simultaneously, the steam pressure is monitored in real time by the pressure sensor 7, and the regulating proportional valve 5 is used to adjust the steam pressure, which helps stabilize the steam pressure and temperature, improving steam quality. Overheated steam or steam containing water is treated at the supply point to prevent damage to downstream equipment, increasing practicality.

[0025] Please see Figure 3 A water supply pipe 21 is fixedly installed above the water supply tank 15. A flow regulating valve 22 is fixedly installed inside the water supply tank 15. One end of the water supply pipe 21 extends into the interior of the water supply tank 15 and is fixedly connected to the flow regulating valve 22. A water distributor 23 is fixedly installed below the flow regulating valve 22. Multiple atomizing nozzles 24 are fixedly installed below the water distributor 23. The height of the air supply pipe 3 14 is lower than the height of the air supply pipe 4 16. A distribution plate 25 is fixedly installed inside the water supply tank 15. Multiple air vents are provided inside the distribution plate 25.

[0026] When water is added when the steam temperature is higher than the equivalent steam saturation temperature, the flow regulating valve 22 can precisely adjust the amount of water added, ensuring that the ratio of added condensate to steam is appropriate, avoiding excessive or insufficient water addition that would affect steam quality. The water distributor 23 and the atomizing nozzle 24 atomize the water evenly, increasing the contact area between water and steam, making the steam cooling process faster and more uniform, effectively reducing the steam temperature, preventing steam overheating, and the distribution plate 25 and its vent holes can buffer and evenly distribute the mixture of steam and water, making the mixture of steam and water more complete and improving the water addition and cooling effect.

[0027] Please see Figure 2 Support plates 17 are symmetrically fixedly installed at the front and rear ends below the water tank 15. A water tank 19 is fixedly installed below the support plates 17. A pump box 20 is fixedly installed at the rear end above the water tank 19. A water pump is installed inside the pump box 20. A water pump is installed at the input end of the water pump and the water pump is inserted into the water tank 19. One end of the water supply pipe 21 extends into the pump box 20 and is connected to the output end of the water pump. A water supply pipe 30 is fixedly installed on one side of the water tank 19. The water supply pipe 30 is connected to a water supply device for water replenishment.

[0028] The water pump ensures a stable water supply from the water tank to the makeup water tank, meeting the makeup water needs of the makeup water mechanism when the steam temperature is too high, reducing the steam temperature in time, and ensuring steam quality. The water supply pipe 30 is connected to an external water supply device, providing a water source to the water tank and ensuring that there is always enough water in the water tank for makeup water operation. This avoids the makeup water mechanism from failing to work properly due to water shortage and ensures that the equipment can stably regulate the steam temperature during long-term operation.

[0029] Please see Figure 1 and Figure 3 A recovery pipe 18 is fixedly installed below the steam-water separator 11. One end of the recovery pipe 18 is fixedly connected to the water tank 19. A return water pipe 26 is fixedly installed in the middle below the water tank 15. The lower end of the return water pipe 26 is fixedly connected to the water tank 19.

[0030] The water separated by the steam-water separator 11 enters the water tank 19 through the recovery pipe 18, and the excess water in the water replenishment tank 15 flows back to the water tank 19 through the return water pipe 26, realizing water recycling for reuse, greatly reducing water waste and lowering water costs.

[0031] Please see Figure 2 and Figure 4 The water tank 19 has heat dissipation plates 27 symmetrically fixed on both sides inside. The heat dissipation plates 27 extend to the outer end face of the water tank 19. Multiple heat dissipation fins 28 are fixedly installed on one side of the heat dissipation plates 27. The heat dissipation fins 28 have several heat dissipation holes inside. Both the heat dissipation plates 27 and the heat dissipation fins 28 are made of die-cast aluminum alloy.

[0032] Die-cast aluminum alloy has good thermal conductivity. The heat dissipation plate 27 can quickly transfer the heat of the water in the water tank 19 to the heat dissipation fins 28. The heat dissipation fins 28 increase the heat dissipation area, and the heat dissipation holes further promote air circulation and accelerate heat dissipation, realizing the natural heat dissipation capacity of the water tank 19, effectively reducing the temperature of the water in the water tank and increasing its practicality.

[0033] Working principle: During use, steam is input through the inlet pipe 1. Temperature sensor 8 monitors the steam temperature in real time. When the steam temperature is detected to be lower than the saturation temperature, the steam-water separation mechanism is activated. Electric valve 9 opens, allowing wet steam to enter the steam-water separator 11 through the gas delivery pipe 10 for water-water separation. Dry steam flows into the direct current pipe 4 through the gas delivery pipe 12. The separated condensate flows back to the water tank 19 through the recovery pipe 18. When the steam temperature is too high, the water replenishment mechanism is activated. Electric valve 13 opens, allowing superheated steam to enter the water replenishment tank 1. 5. Simultaneously, the water pump adjusts the water in the water tank 19 through the flow regulating valve 22, and then sprays it evenly through the atomizing nozzle 24. It mixes thoroughly with the steam to cool it down. The cooled steam flows into the direct current pipe 4 through the gas supply pipe 16. Excess water returns to the water tank 19 through the return water pipe 26 for recycling. When the steam temperature is within the steam saturation temperature range, the electric valve opens, and the steam flows into the direct current pipe 4. Then, when the steam is supplied and output, the pressure is adjusted by the regulating proportional valve 5 and then output from the gas supply pipe 6 to the subsequent distribution equipment, which increases its practicality.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
