Description

Technical Field

[0001] This utility model relates to the field of de-temperature and de-pressure technology, specifically a multi-channel de-temperature and de-pressure device. Background Technology

[0002] A desuperheating and pressure reducing device is an energy-saving device that reduces the steam parameters provided by the user to the appropriate temperature and pressure required by the user, so as to meet the user's requirements and fully save heat energy and make rational use of heat energy. It generally consists of a main steam pipe body, a safety protection system, a thermal control system, etc.

[0003] A search revealed a desuperheating and pressure reducing device disclosed in Chinese Utility Model Patent No. CN220135221U. This utility model patent is designed with two desuperheating water control and regulation systems: a small desuperheating water control and regulation system and a large desuperheating water control and regulation system. When the main body of the desuperheating and pressure reducing device is under high load, the large desuperheating water control and regulation system is used to regulate the steam temperature. The pipe diameter of the water supply pipe in the large desuperheating water control and regulation system is designed to meet the desuperheating water volume required for the rated flow of the main body of the desuperheating and pressure reducing device. When the main body of the desuperheating and pressure reducing device is under low load (below 30% load), the small desuperheating water control and regulation system is used to regulate the steam temperature. This completely solves the safety hazard of the outlet temperature of the desuperheating and pressure reducing device fluctuating and difficult to control when the main body of the desuperheating and pressure reducing device is running under low load.

[0004] However, in actual use, water is directly injected into the main pipe through the pipeline, which can easily lead to uneven mixing of steam and water, resulting in low cooling efficiency. In addition, the device requires a regulating valve to control the flow rate, which can easily lead to low operating accuracy and water volume not meeting the requirements. Therefore, a multi-channel de-cooling and pressure reducing device is proposed to solve the above problems. Utility Model Content

In addition, the device requires a regulating valve to control the flow rate, which easily leads to low operating accuracy and water volume not meeting the requirements.

[0009] Furthermore, the main body extends through the sleeve, and there are two temperature sensors and two pressure sensors.

[0010] Furthermore, the temperature sensor on the left is located near the air intake, and the temperature sensor on the right is located near the exhaust.

[0011] Furthermore, both pressure sensors are located between the two temperature sensors, and there are three of each of the first and second fixing rings, with the first and second fixing rings spaced apart.

[0012] Furthermore, there are three sets of both large-hole nozzles and small-hole nozzles, with ten large-hole nozzles in each set, which are equidistantly distributed inside the first fixing ring.

[0013] Furthermore, the three first branch pipes extend to the outside of the sleeve and are connected to the first water inlet pipe on the side away from the three first fixing rings, and the three second branch pipes are connected to the second water inlet pipe on the side away from the three second fixing rings.

[0014] Furthermore, both the inlet pipe and the second inlet pipe are fixedly installed with a delivery pump, and both the inlet pipe and the second inlet pipe are equipped with a one-way solenoid valve.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The multi-channel de-cooling and de-pressure reducing device in this embodiment includes a main body 1, a sleeve 2 installed on the outside of the main body 1, an air inlet 3 on the left side of the main body 1, an exhaust port 4 on the right side of the main body 1, and auxiliary mechanisms 5 provided inside and outside the sleeve 2.

[0025] The auxiliary mechanism 5 includes a temperature sensor 501, a pressure sensor 502 fixedly mounted on the top of the main body 1, a first fixing ring 503 fixedly mounted on the outside of the main body 1, a large-hole nozzle 504 fixedly mounted on the inner wall of the first fixing ring 503, a second fixing ring 505 fixedly mounted on the outside of the main body 1, a small-hole nozzle 506 fixedly mounted on the inner wall of the second fixing ring 505, a first branch pipe 507 fixedly mounted on the top of the first fixing ring 503, a first water inlet pipe 508 connected to the top of the first branch pipe 507, a second branch pipe 509 connected to the bottom of the second fixing ring 505, and a second water inlet pipe 510 connected to the bottom of the second branch pipe 509.

[0026] Specifically, through the cooperation of the various structures of the auxiliary mechanism 5, it is possible to input different amounts of water according to different loads, and to ensure that the steam and water are mixed more evenly, resulting in higher cooling efficiency.

[0027] exist Figure 1 and Figure 2 In the middle, the main body 1 is externally connected to a pressure relief pipe 6, a pressure relief valve 7 is fixedly installed on the outside of the pressure relief pipe 6, and a pressure gauge 8 is fixedly installed on the outside of the pressure relief pipe 6.

[0028] Specifically, the pressure relief valve 7 is activated by the controller, and the pressure is discharged through the pressure relief pipe 6, thus achieving the pressure reduction effect.

[0029] exist Figure 1 and Figure 2 In the middle, the main body 1 passes through the sleeve 2, and there are two temperature sensors 501 and two pressure sensors 502.

[0030] Specifically, by setting pressure sensors 502, one detects the pressure at 3 points in the air intake and the other detects the pressure at 4 points in the exhaust port, ensuring that the pressure relief meets the requirements.

[0031] exist Figure 1 and Figure 3 In the middle, the left temperature sensor 501 is closer to the air inlet 3, and the right temperature sensor 501 is closer to the exhaust outlet 4.

[0032] Specifically, by setting two sets of temperature sensors 501, one is responsible for detecting the temperature of the steam input from the air inlet 3, and the other is responsible for detecting the temperature of the steam after cooling is completed, so as to ensure that the cooling meets the requirements.

[0033] exist Figure 2 and Figure 3 In the middle, two pressure sensors 502 are located between two temperature sensors 501. There are three first fixing rings 503 and three second fixing rings 505, and the first fixing rings 503 and the second fixing rings 505 are arranged at intervals.

[0034] Specifically, the large-hole nozzle 504 is fixed by setting the first fixing ring 503. When the steam pressure detection load is high, the controller drives the delivery pump 9 to start, and the water in the first water inlet pipe 508 will enter the first branch pipe 507, thereby supplying water to the large-hole nozzle 504.

[0035] exist Figure 2 and Figure 3 In the middle, there are three sets of large-hole nozzles 504 and small-hole nozzles 506. Each set of large-hole nozzles 504 has ten nozzles and they are evenly distributed inside the first fixing ring 503.

[0036] exist Figure 2 and Figure 4In the middle, the three first branch pipes 507 extend to the outside of the sleeve 2 on the side away from the three first fixing rings 503 and are connected to the first water inlet pipe 508. The three second branch pipes 509 are connected to the second water inlet pipe 510 on the side away from the three second fixing rings 505.

[0037] Specifically, the second fixing ring 505 is used to limit the small hole nozzle 506. When the load is small, the controller drives the bottom delivery pump 9 to start, and water is delivered to the second fixing ring 505 and the small hole nozzle 506 through the second branch pipe 509.

[0038] exist Figure 2 and Figure 5 In the middle, a delivery pump 9 is fixedly installed on the outside of the water inlet pipe 508 and the second water inlet pipe 510, and a one-way solenoid valve 10 is installed on the outside of the water inlet pipe 508 and the second water inlet pipe 510.

[0039] During implementation, the following steps are performed: When in use, steam first enters the main body 1 through the air inlet 3. At this time, the pressure sensor 502 and temperature sensor 501 on the left side will detect the steam and transmit the data to the designated pan-tilt unit. Then, according to the monitored load, but less than 30Q, the controller drives the bottom delivery pump 9 to start. At this time, the second water inlet pipe 510 supplies water to the second fixed ring 505 and the small nozzle 506 through the second branch pipe 509. The small nozzle 506 sprays water to cool the steam. At the same time, the pressure relief valve 7 is activated, and the pressure relief pipe 6 relieves pressure. When the steam moves to the end near the exhaust port 4, the pressure sensor 502 and temperature sensor 501 will detect the gas after the cooling and pressure reduction are completed. Similarly, when the load on the main body 1 is large, water is sprayed by the large nozzle 504 to cool and reduce pressure.

[0040] In summary, by setting two sets of temperature sensors 501, one responsible for detecting the temperature of the steam input from the air inlet 3 and the other responsible for detecting the temperature of the steam after cooling, the cooling is ensured to meet the requirements. By setting pressure sensors 502, one detects the pressure at the air inlet 3 and the other detects the pressure at the exhaust outlet 4, the pressure relief is ensured to meet the requirements. By setting a first fixing ring 503 to fix the large-hole nozzle 504, when the steam pressure detection load is high, the controller drives the delivery pump 9 to start, and the water in the first water inlet pipe 508 will enter the first branch pipe 507 to supply water to the large-hole nozzle 504. By setting a second fixing ring 505 to limit the small-hole nozzle 506, when the load is small, the controller drives the delivery pump 9 at the bottom to start, and water is supplied to the second fixing ring 505 and the small-hole nozzle 506 through the second branch pipe 509. By setting the large-hole nozzle 504 and the small-hole nozzle 506 in a ring shape, the water output is ensured to be more uniform, thereby making the steam and water mix more evenly and the cooling efficiency higher.
