Annular nozzle temperature and pressure reducing device

Abstract

According to the annular nozzle temperature and pressure reducing device, when steam enters a pipe body from a steam inlet and then enters a venturi tube, after the steam enters a narrow channel in the venturi tube, the flow speed is increased, the pressure is reduced, and then a temperature reducing water switch is turned on to enable temperature reducing water to be sprayed out from the atomizing end of a temperature reducing water pipeline; meanwhile, due to the fact that the annular pipeline is communicated with the attemperation water pipeline and the inner spaces of the multiple nozzles, in other words, attemperation water flows into the first spring nozzle, the second spring nozzle, the third spring nozzle and the fourth spring nozzle after passing through the attemperation water pipeline and the annular pipeline, and adjustment of the large change range of multiple working conditions is achieved by selecting the number of the opened nozzles; and after temperature reduction of the temperature reduction water, the steam flows out of the steam outlet of the pipe body, so that pressure reduction and temperature reduction of the steam are realized.

Description

Technical Field

[0001] This utility model belongs to the technical field of de-heating and de-pressure devices, and particularly relates to a ring nozzle de-heating 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 cogeneration, centralized heating (or steam supply), and enterprises in light industry, power, chemical industry, and textile industry. Through this 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 heat energy can be fully saved and used rationally.

[0003] Existing de-cooling and pressure-reducing devices cannot achieve a wide range of adjustment functions under different operating conditions according to different pressure differences and flow rates, which limits their application. Therefore, this utility model proposes a ring nozzle de-cooling and pressure-reducing device to solve the above problems. Utility Model Content

[0004] This invention provides a ring nozzle cooling and pressure reducing device, which aims to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a ring nozzle cooling and pressure reducing device includes a tube body and a spring atomizing nozzle assembly.

[0006] One side of the tube is a steam inlet, and the other side is a steam outlet. The spring atomizing nozzle assembly is located near the steam inlet of the tube. A venturi tube is provided inside the tube.

[0007] The spring atomizing nozzle assembly includes a desuperheating water pipe, an annular pipe, and multiple nozzles. The desuperheating water pipe and multiple nozzles are distributed in a ring shape on the outside of the pipe body and are all connected to the inside of the Venturi tube. The annular pipe connects the internal space of the desuperheating water pipe and multiple nozzles.

[0008] Preferably, a stop is provided on the inner wall of the tube near the steam outlet, the stop being used to limit the Venturi tube.

[0009] Preferably, the tube body and the venturi tube are connected by a slider.

[0010] Preferably, a nameplate holder is provided on the outer wall of the tube, and a nameplate is provided on the nameplate holder.

[0011] Preferably, the pipe body is provided with a supporting web near the steam outlet.

[0012] Preferably, the plurality of nozzles includes spring nozzle one, spring nozzle two, spring nozzle three and spring nozzle four, and the desuperheating water pipe, spring nozzle one, spring nozzle two, spring nozzle three and spring nozzle four are distributed in a ring shape.

[0013] Preferably, the desuperheating water pipe is connected to the pipe body and the venturi tube via a pipe seat.

[0014] Preferably, the spring nozzle one, spring nozzle two, spring nozzle three and spring nozzle four are connected to the tube body and the venturi tube through spring nozzle seats.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] After steam enters the tube body through the steam inlet, it then enters the venturi tube. As the steam enters the narrow channel of the venturi tube, the flow rate increases and the pressure decreases. Then, the desuperheating water switch is opened, causing the desuperheating water to spray out from the atomizing end of the desuperheating water pipe. At the same time, because the annular pipe connects the desuperheating water pipe and the internal space of multiple nozzles, the desuperheating water flows into spring nozzle one, spring nozzle two, spring nozzle three, and spring nozzle four respectively after passing through the desuperheating water pipe and the annular pipe. By selecting the number of nozzles to open, a wide range of adjustment under various operating conditions can be achieved. After being desuperheated by the desuperheating water, the steam flows out from the steam outlet of the tube body, realizing the decompression and desuperheating of the steam.

[0026] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a ring nozzle de-cooling and pressure reducing device, including a tube body 1 and a spring atomizing nozzle assembly; one side of the tube body 1 is a steam inlet and the other side is a steam outlet, the spring atomizing nozzle assembly is located near the steam inlet of the tube body 1, and a Venturi tube 2 is provided inside the tube body 1; the spring atomizing nozzle assembly includes a de-cooling water pipe 8, a ring pipe 15 and multiple nozzles, the pipe 8 and multiple nozzles are distributed in a ring shape on the outside of the tube body 1 and are all connected to the inside of the Venturi tube 2, and the ring pipe 15 connects the internal space of the de-cooling water pipe 8 and multiple nozzles.

[0027] Furthermore, a stop 7 is provided on the inner wall of the tube body 1 near the steam outlet, and the stop 7 is used to limit the Venturi tube 2.

[0028] Furthermore, tube 1 and venturi tube 2 are connected by slider 3.

[0029] Furthermore, a nameplate holder 4 is provided on the outer wall of the tube body 1, and a nameplate 5 is provided on the nameplate holder 4.

[0030] Furthermore, a supporting web 6 is provided near the steam outlet of the pipe body 1.

[0031] Furthermore, multiple nozzles, including spring nozzle one 10, spring nozzle two 12, spring nozzle three 13 and spring nozzle four 14, are arranged in a ring shape in the desuperheating water pipe 8.

[0032] Furthermore, the desuperheating water pipe 8 is connected to the pipe body 1 and the venturi tube 2 via the pipe seat 9.

[0033] Furthermore, spring nozzle 10, spring nozzle 2 12, spring nozzle 3 13 and spring nozzle 4 14 are connected to the tube body 1 and the venturi tube 2 via spring nozzle seat 11.

[0034] In this embodiment, one side of the pipe body 1 is a steam inlet, and the other side is a steam outlet. After steam enters the pipe body 1 through the steam inlet, it then enters the venturi tube 2. (See attached diagram.) Figure 1 The narrow channel in the Venturi tube 2 is located at the same position as the spring atomizing nozzle assembly. When steam enters the narrow channel in the Venturi tube 2, the flow rate increases and the pressure decreases, thereby achieving flow control. The desuperheating water pipe 8 is connected to a desuperheating water pipe at one end and the atomizing end is located inside the narrow channel in the Venturi tube 2 at the other end. After the steam passes through the narrow channel in the Venturi tube 2, the pressure is reduced, and then the desuperheating water switch is opened to spray the desuperheating water from the atomizing end of the desuperheating water pipe 8. At the same time, since the annular pipe 15 connects the desuperheating water pipe 8 and the internal space of multiple nozzles, the desuperheating water flows into the spring nozzle 10, spring nozzle 2 12, spring nozzle 3 13 and spring nozzle 4 14 respectively after passing through the desuperheating water pipe 8 and the annular pipe 15. At this time, the number of nozzles can be selected to open. Depending on the pressure difference and flow rate required, one nozzle or multiple nozzles can be opened. By selecting the number of nozzles to open, a wide range of adjustment under multiple working conditions can be achieved. After being desuperheated by the desuperheating water, the steam flows out from the steam outlet of the tube body 1, realizing the decompression and desuperheating of the steam.

[0035] The working principle and usage process of this utility model are as follows: When steam enters the pipe body 1 from the steam inlet, it then enters the venturi tube 2. When the steam enters the narrow channel in the venturi tube 2, the flow rate increases and the pressure decreases. Then, the desuperheating water switch is opened, causing the desuperheating water to spray out from the atomizing end of the desuperheating water pipe 8. At the same time, since the annular pipe 15 connects the desuperheating water pipe 8 and the internal space of multiple nozzles, the desuperheating water flows into spring nozzle 10, spring nozzle 2 12, spring nozzle 3 13 and spring nozzle 4 14 respectively after passing through the desuperheating water pipe 8 and the annular pipe 15. The adjustment of a large range of multiple working conditions can be achieved by selecting the number of nozzles to open. After being desuperheated by the desuperheating water, the steam flows out from the steam outlet of the pipe body 1, realizing the decompression and desuperheating of the steam.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
