Description

Technical Field

[0001] This utility model relates to the technical field of de-cooling and de-pressure devices, specifically a split-type de-cooling and de-pressure device. Background Technology

[0002] The desuperheating and pressure reducing device is a steam thermal energy parameter (pressure, temperature) conversion device and waste heat energy energy utilization energy device widely used in modern industry, such as combined heat and power, centralized heating (or steam supply), and enterprises in light industry, power, chemical industry, and textile industry. Through the device, the steam parameters provided by the user are reduced to the appropriate temperature and pressure required by the user to meet the user's requirements, and the thermal energy can be fully saved and used rationally.

[0003] In existing split-type desuperheating and pressure reducing devices, desuperheating water is transported to the steam output end through pipelines and then atomized and sprayed by atomizing nozzles. This structural design reduces the service life of the atomizing nozzles due to high temperatures. Once the atomizing nozzles are damaged, it will affect the normal operation of the device. To address this issue, a split-type desuperheating and pressure reducing device is needed. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the existing split-type de-cooling and de-pressure reducing devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a split-type desuperheating and pressure reducing device. A water pump delivers desuperheating water from the storage tank to the atomization section. When high-pressure, high-temperature steam is depressurized through the pressure reducing orifice plate and pressure reducing valve, it enters the atomization section. When the steam enters the middle of the atomization section, the low-pressure, high-temperature steam will increase the pressure. The briefly pressurized high-temperature steam atomizes the desuperheating water and mixes it with the high-temperature steam before being discharged into the steam output pipe to reduce the pressure, thus achieving the effect of cooling and depressurizing. Compared with the prior art, it does not require an atomizing nozzle, thereby improving the service life of the device.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A split-type desuperheating and pressure reducing device, comprising a steam inlet pipe and a steam outlet pipe;

[0009] A pressure reducing valve is installed on the steam inlet pipe, and a pressure reducing orifice plate is installed inside the steam inlet pipe. The steam inlet pipe is connected to the steam outlet pipe through an atomizing section. A pressure relief valve, a temperature sensor, a pressure sensor, and a gas-liquid separator are installed on the steam outlet pipe. The gas-liquid separator is connected to a storage tank through a pipe. The storage tank is connected to the atomizing section through a water supply pipe. A water pump is installed between the water supply pipe and the storage tank.

[0010] As a preferred embodiment of the split-type de-icing and de-pressure device of this utility model, wherein: the diameters at both ends of the atomizing section are larger than the diameter in the middle, and the water supply pipe is connected to the atomizing section.

[0011] As a preferred embodiment of the split-type de-heating and de-pressure device described in this utility model, the water supply pipe is provided with a shut-off valve, a throttle valve and a water supply regulating valve in sequence from right to left.

[0012] As a preferred embodiment of the split-type de-temperature and pressure reducing device described in this utility model, a temperature sensor and a pressure sensor are further provided on the steam output pipe, and the detection ends of the temperature sensor and the pressure sensor are located in the inner cavity of the steam output pipe.

[0013] As a preferred embodiment of the split-type de-cooling and de-pressure device described in this utility model, there are multiple pressure-reducing orifice plates, and the number of through holes on the pressure-reducing orifice plates decreases sequentially from the steam inlet end to the atomization section.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the desuperheating water in the storage tank is transported to the atomization section by a water pump. When the high-pressure high-temperature steam is depressurized by the pressure reducing plate and pressure reducing valve, it enters the atomization section. When the steam enters the middle of the atomization section, the low-pressure high-temperature steam will increase the pressure. The briefly pressurized high-temperature steam atomizes the desuperheating water and mixes it with the high-temperature steam before being discharged into the steam output pipe to reduce the pressure, thereby achieving the effect of cooling and depressurization. Compared with the prior art, there is no need for an atomizing nozzle, thus improving the service life of the device. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides the following technical solution: a split-type desuperheating and pressure reducing device. During use, a water pump delivers desuperheating water from the storage tank to the atomization section. When high-pressure, high-temperature steam is depressurized through the pressure reducing orifice plate and pressure reducing valve, it enters the atomization section. When the steam enters the middle of the atomization section, the low-pressure, high-temperature steam will increase the pressure. The briefly pressurized high-temperature steam atomizes the desuperheating water and mixes it with the high-temperature steam before being discharged into the steam output pipe to reduce the pressure, thus achieving the effect of cooling and depressurizing. Compared with the prior art, it does not require an atomizing nozzle, thereby improving the service life of the device.

[0025] Figures 1-3 The diagram shown is a structural schematic of the first embodiment of a split-type de-icing and de-pressure device according to this utility model. Please refer to [link / reference]. Figures 1-3 The main body of the split-type desuperheating and pressure reducing device of this embodiment includes a steam inlet pipe 100 and a steam outlet pipe 200.

[0026] A pressure reducing valve 110 is installed on the steam inlet pipe 100, and a pressure reducing orifice plate 120 is installed inside the steam inlet pipe 100. The steam inlet pipe 100 is connected to the steam outlet pipe 200 through the atomizing section 130. The steam outlet pipe 200 is equipped with a pressure relief valve 210, a temperature sensor 220, a pressure sensor 230, and a gas-liquid separator 240. The gas-liquid separator 240 is connected to the liquid storage tank 250 through a pipe. The liquid storage tank 250 is connected to the atomizing section 130 through a water supply pipe 260. A water pump 270 is installed between the water supply pipe 260 and the liquid storage tank 250.

[0027] The diameters at both ends of the atomizing section 130 are larger than the diameter in the middle. The water supply pipe 260 is connected to the atomizing section 130. From right to left, the water supply pipe 260 is equipped with a shut-off valve 261, a throttle valve 262, and a water supply regulating valve 263. The steam output pipe 200 is also equipped with a temperature sensor 220 and a pressure sensor 230. The detection ends of the temperature sensor 220 and the pressure sensor 230 are located in the inner cavity of the steam output pipe 200. There are multiple pressure reducing orifice plates 120, and the number of through holes on the pressure reducing orifice plates 120 decreases sequentially from the steam inlet end to the atomizing section 130.

[0028] The steam inlet pipe 100 carries the pressure reducing valve 110 and the pressure reducing orifice plate 120, which can reduce the pressure of high-temperature and high-pressure steam. The atomizing section 130 connects the steam inlet pipe 100 and the steam outlet pipe 200, and briefly pressurizes and then depressurizes the low-pressure and high-temperature steam. The high-pressure and high-temperature steam atomizes the desuperheating water, achieving mixing with the high-temperature and high-pressure steam and thus cooling the steam. The steam outlet pipe 200 carries the pressure relief valve 210, temperature sensor 220, pressure sensor 230, and gas-liquid separator 240. 10 is used to reduce the pressure in the steam output pipe 200 when the pressure is too high. Temperature sensor 220 and pressure sensor 230 are used to detect the pressure and temperature in the steam output pipe 200. Gas-liquid separator 240 is used to separate gas and liquid in the steam. Liquid storage tank 250 is used to store desuperheating water. Water supply pipe 260 is used to connect atomizing section 130 and liquid storage tank 250. Shut-off valve 261 is used to control the opening and closing of water supply pipe 260. Throttling valve 262 is used to control the flow rate and pressure of water supply pipe 260. Water supply regulating valve 263 is used to automatically adjust the valve opening size according to the demand for desuperheating water.

[0029] Working principle: The desuperheating water in the storage tank 250 is transported to the atomizing section 130 by the water pump 270. After the high-pressure high-temperature steam is depressurized by the pressure reducing plate 120 and the pressure reducing valve 110, it enters the atomizing section 130. When the steam enters the middle of the atomizing section 130, the low-pressure high-temperature steam will increase the pressure. The briefly pressurized high-temperature steam will atomize the desuperheating water and mix it with the high-temperature steam before being discharged into the steam output pipe 200 to reduce the pressure, thus achieving the effect of cooling and depressurization. Compared with the existing technology, it does not require an atomizing nozzle, thereby improving the service life of the device.
