Description

Technical Field

[0001] This utility model relates to the field of de-cooling and de-pressure technology, and in particular to a de-cooling and de-pressure device with waste heat recovery function. Background Technology

[0002] A desuperheater / pressure reducer is an industrial device used to convert high-temperature, high-pressure steam into low-temperature, low-pressure steam.

[0003] The main function of a desuperheater and pressure reducer is to reduce the temperature and pressure of steam. When high-temperature and high-pressure steam passes through the desuperheater and pressure reducer, the steam undergoes temperature and pressure reduction. Since the desuperheater and pressure reducer does not utilize the high temperature and high pressure of the steam directly, the high-temperature and high-pressure steam is now first heat utilized before entering the desuperheater and pressure reducer. For example, the high-temperature steam is used to heat the liquid, thereby achieving the effect of waste heat utilization. Moreover, the desuperheated steam only requires a small amount of power to reach the required temperature when passing through the desuperheater and pressure reducer.

[0004] However, most current methods of utilizing high-temperature and high-pressure steam involve directly heating liquids, which is ineffective. Furthermore, the high pressure of the high-temperature and high-pressure steam is not utilized. Therefore, we propose a de-temperature and pressure reducing device with waste heat recovery function. Utility Model Content

[0005] The purpose of this invention is to provide a de-cooling and de-pressure reducing device with waste heat recovery function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a de-cooling and pressure-reducing device with waste heat recovery function, comprising:

[0007] The desuperheating and pressure reducing device body has a water storage mechanism inside.

[0008] A flow channel assembly is disposed inside the body of the desuperheater and pressure reducer. The flow channel assembly is used to guide the steam entering the body of the desuperheater and pressure reducer. The flow channel assembly includes a central shaft disposed inside the body of the desuperheater and pressure reducer, and a spiral blade is fixedly sleeved on the outer wall of the central shaft.

[0009] Preferably, a second connecting ring is fixedly sleeved on both sides of the outer wall of the de-cooling and pressure reducing device, and a plurality of second connecting holes are opened on one side of the second connecting ring.

[0010] Preferably, a water inlet pipe is fixedly connected to the top of the outer wall of the desuperheater and pressure reducer body, and the inside of the water inlet pipe is connected to the inside of the water storage mechanism. A water outlet pipe is fixedly connected to the bottom of the outer wall of the desuperheater and pressure reducer body, and the inside of the water outlet pipe is connected to the inside of the water storage mechanism. A valve is installed inside the water outlet pipe.

[0011] Preferably, the ends of the inlet pipe and the outlet pipe are both fixedly sleeved with a first connecting ring, and the top end of the first connecting ring is provided with a plurality of first connecting holes.

[0012] Preferably, the water storage mechanism includes a water storage cylinder, which is fixedly inserted into the inner wall of the desuperheater body. The interior of the water storage cylinder is connected to the interior of the inlet pipe and the outlet pipe, respectively. The outer wall of the spiral blade is fixedly connected to the inner wall of the water storage cylinder.

[0013] Preferably, the water storage mechanism includes a spiral tube, which is fixedly connected to the inner wall of the desuperheater body. The two ends of the spiral tube are respectively connected to the interior of the inlet pipe and the outlet pipe, and the outer wall of the spiral blade is fixedly connected to the outer wall of the spiral tube.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention utilizes a central shaft and spiral blades. The spiral blades guide the steam within the desuperheater and pressure reducer, causing the steam to spiral forward within the blades. This increases the steam's movement path within the desuperheater and pressure reducer, prolonging the contact time between the steam and the water storage mechanism and improving waste heat recovery efficiency. Simultaneously, the spiral blades gradually slow down the steam as it passes through them, allowing for a pre-decompression before the steam undergoes desuperheating and pressure reduction, thus reducing the power consumption of the desuperheater and pressure reducer.

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.

[0022] Example 1:

[0023] The device includes a desuperheating and pressure reducing device body 101 and a flow channel assembly. The desuperheating and pressure reducing device body 101 is equipped with a water storage mechanism. High-temperature and high-pressure steam enters the desuperheating and pressure reducing device body 101 for desuperheating and pressure reducing and then discharges. The high-temperature steam can heat the liquid inside the water storage mechanism by contacting it, so that the high-temperature steam is desuperheated before desuperheating and pressure reducing, which can achieve the effect of waste heat recovery and also reduce the power of the desuperheating and pressure reducing device body 101.

[0024] In a preferred embodiment, a flow channel assembly is disposed inside the desuperheater and pressure reducer body 101. The flow channel assembly is used to guide the steam entering the desuperheater and pressure reducer body 101. The flow channel assembly includes a central shaft 201 disposed inside the desuperheater and pressure reducer body 101. A spiral blade 202 is fixedly sleeved on the outer wall of the central shaft 201. The spiral blade 202 guides the steam inside the desuperheater and pressure reducer body 101 in a spiral manner, so that the steam will spiral forward inside the spiral blade 202. This increases the movement path of the steam inside the desuperheater and pressure reducer body 101, prolongs the contact time between the steam and the water storage mechanism, and improves the waste heat recovery efficiency. At the same time, the arrangement of the spiral blade 202 will cause the steam to gradually slow down when passing through the spiral blade 202, so that the steam can be depressurized once before desuperheating and pressure reducing, thereby reducing the power of the desuperheater and pressure reducer body 101.

[0025] The desuperheater and pressure reducer body 101 has a second connecting ring 601 fixedly sleeved on both sides of its outer wall. The second connecting ring 601 has multiple second connecting holes 602 on one side. The second connecting ring 601 and the second connecting holes 602 facilitate the connection of the desuperheater and pressure reducer body 101 to the external steam pipe, thereby improving the ease of use of the desuperheater and pressure reducer body 101.

[0026] The top of the outer wall of the desuperheater 101 is fixedly connected to an inlet pipe 401, and the inside of the inlet pipe 401 is connected to the inside of the water storage mechanism. The bottom of the outer wall of the desuperheater 101 is fixedly connected to an outlet pipe 402, and the inside of the outlet pipe 402 is connected to the inside of the water storage mechanism. A valve 403 is installed inside the outlet pipe 402. By injecting liquid into the water storage tank 301 through the inlet pipe 401, steam can be used to heat the liquid inside the water storage tank 301 when it passes through the water storage tank 301. The valve 403 is used to control the flow of liquid in the water storage tank 301.

[0027] The inlet pipe 401 and the outlet pipe 402 are both fixedly sleeved with a first connecting ring 501. The top of the first connecting ring 501 is provided with a plurality of first connecting holes 502, which facilitate the connection of the inlet pipe 401 and the outlet pipe 402 with external pipes.

[0028] The water storage mechanism includes a water storage cylinder 301, which is fixedly connected to the inner wall of the desuperheater and pressure reducer body 101. The interior of the water storage cylinder 301 is connected to the interior of the inlet pipe 401 and the outlet pipe 402 respectively. The outer wall of the spiral blade 202 is fixedly connected to the inner wall of the water storage cylinder 301. Liquid enters the interior of the water storage cylinder 301 through the inlet pipe 401, so that steam can heat the liquid inside the water storage cylinder 301 when it passes through the water storage cylinder 301. When the valve 403 is closed, the liquid is filled into the water storage cylinder 301, so that the maximum volume of liquid can be heated.

[0029] Example 2:

[0030] The device includes a desuperheating and pressure reducing device body 101 and a flow channel assembly. The desuperheating and pressure reducing device body 101 is equipped with a water storage mechanism. High-temperature and high-pressure steam enters the desuperheating and pressure reducing device body 101 for desuperheating and pressure reducing and then discharges. The high-temperature steam can heat the liquid inside the water storage mechanism by contacting it, so that the high-temperature steam is desuperheated before desuperheating and pressure reducing, which can achieve the effect of waste heat recovery and also reduce the power of the desuperheating and pressure reducing device body 101.

[0031] In a preferred embodiment, a flow channel assembly is disposed inside the desuperheater and pressure reducer body 101. The flow channel assembly is used to guide the steam entering the desuperheater and pressure reducer body 101. The flow channel assembly includes a central shaft 201 disposed inside the desuperheater and pressure reducer body 101. A spiral blade 202 is fixedly sleeved on the outer wall of the central shaft 201. The spiral blade 202 guides the steam inside the desuperheater and pressure reducer body 101 in a spiral manner, so that the steam will spiral forward inside the spiral blade 202. This increases the movement path of the steam inside the desuperheater and pressure reducer body 101, prolongs the contact time between the steam and the water storage mechanism, and improves the waste heat recovery efficiency. At the same time, the arrangement of the spiral blade 202 will cause the steam to gradually slow down when passing through the spiral blade 202, so that the steam can be depressurized once before desuperheating and pressure reducing, thereby reducing the power of the desuperheater and pressure reducer body 101.

[0032] The desuperheater and pressure reducer body 101 has a second connecting ring 601 fixedly sleeved on both sides of its outer wall. The second connecting ring 601 has multiple second connecting holes 602 on one side. The second connecting ring 601 and the second connecting holes 602 facilitate the connection of the desuperheater and pressure reducer body 101 to the external steam pipe, thereby improving the ease of use of the desuperheater and pressure reducer body 101.

[0033] The top of the outer wall of the desuperheater 101 is fixedly connected to an inlet pipe 401, and the inside of the inlet pipe 401 is connected to the inside of the water storage mechanism. The bottom of the outer wall of the desuperheater 101 is fixedly connected to an outlet pipe 402, and the inside of the outlet pipe 402 is connected to the inside of the water storage mechanism. A valve 403 is installed inside the outlet pipe 402. By injecting liquid into the spiral tube 701 through the inlet pipe 401, the steam can heat the liquid inside the spiral tube 701 when it passes through the spiral tube 701. The valve 403 is used to control the flow of liquid in the spiral tube 701.

The top of the first connecting ring 501 is provided with a plurality of first connecting holes 502, which facilitate the connection of the inlet pipe 401 and the outlet pipe 402 with external pipes.

[0035] The water storage mechanism includes a spiral tube 701, which is fixedly connected to the inner wall of the desuperheater body 101. The two ends of the spiral tube 701 are respectively connected to the interior of the inlet pipe 401 and the outlet pipe 402.
