[0011] Beneficial Effects

[0012] 1.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0022] Reference Figure 1-4 , the utility model embodiment of a high-pressure steam silencer, which includes: a shell 1, which is used as the main structure of the silencer to protect internal components, a dispersion shell 2 is fixedly connected to the upper surface of the shell 1, which is used for uniform diffusion of steam to avoid local high pressure and noise, and a ventilation hole 5 is arranged on the side surface of the dispersion shell 2 for diffusion of steam to avoid local high pressure and noise, a support plate 8 is fixedly connected to the inner wall of the shell 1 for supporting a silencer pipe 6, and a silencer pipe 6 is fixedly connected to the upper surface of the support plate 8 for reducing noise, a circulation pipe 7 is fixedly connected to the inner wall of the shell 1 for heat exchange with the outer wall of the silencer pipe 6, the circulation pipe 7 is wound around the outer side of the silencer pipe 6 to ensure effective temperature reduction, the circulation pipe 7 passes through the shell 1 and extends to the outside of the shell 1, the circulation pipe 7 is provided with a water inlet 12 for receiving cooling water from the chiller 3, and the circulation pipe 7 is provided with a water outlet 13 for discharging the cooling water after heat exchange.

[0023] The water inlet 12 and the water outlet 13 are located on the right side of the circulation pipe 7 and outside the shell 1. The water inlet 12 and the water outlet 13 are fixedly connected with the delivery pipe 4 for connecting the water chiller 3 and the water inlet 12 and the water outlet 13 of the circulation pipe 7. The delivery pipe 4 is fixedly connected to the water chiller 3 at one end away from the circulation pipe 7 for providing cooling water. An air outlet 9 is provided on the upper surface of the shell 1 for discharging treated steam. A diversion port 11 is provided on the upper surface of the support plate 8 for preliminarily diverting the steam entering the silencer so that the steam can evenly enter the silencer pipe 6. The silencer pipe 6 passes through the diversion port 11 and the air outlet 9. The dispersion shell 2 covers the air outlet 9. An air inlet 10 is provided at the lower end of the shell 1, which is the entrance for steam to enter the silencer. The support plate 8 is located directly above the air inlet 10.

[0024] Working principle: High-temperature and high-pressure steam enters the silencer through the air inlet 10 at the lower end of the shell 1. In the process of flowing upward, the steam first encounters the support plate 8. The diversion port 11 on the support plate 8 performs preliminary diversion on the steam, so that the steam is evenly distributed in each silencer pipe 6. When the steam flows into the silencer pipe 6, the noise generated by the high-speed flow is reduced. The circulation pipe 7 is tightly wound around the outside of the silencer pipe 6. The circulation pipe 7 receives cooling water from the chiller 3 through the water inlet 12. The cooling water flows inside the circulation pipe 7, exchanges heat with the outer wall of the silencer pipe 6, and absorbs the steam. The heat transferred by the steam through the silencer pipe 6 reduces the steam temperature in the silencer pipe 6, further reducing the noise generation. After heat exchange, the cooling water temperature increases, flows out of the circulation pipe 7 through the water outlet 13, and returns to the chiller 3 through the delivery pipe 4 for cooling, forming a recycling of cooling water. The temperature and pressure of the steam treated by the silencer pipe 6 are effectively reduced, and finally discharged through the air outlet 9 on the upper surface of the shell 1. The dispersion shell 2 covers the air outlet 9, and the ventilation holes 5 arranged on its side surface are conducive to the uniform diffusion of the steam, avoiding the generation of local high pressure and noise.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
