[0002] In the chemical industry, steam is usually used to promote some chemical reactions. Chemical production equipment uses low-temperature and low-pressure steam as well as high-temperature and high-pressure steam. The low-temperature and low-pressure steam needs to be obtained by cooling and reducing the pressure of high-temperature and high-pressure steam. This method will lose a lot of energy consumption, cause waste of resources, increase the production and manufacturing costs of enterprises, and is not conducive to energy conservation and emission reduction of enterprises. In addition, after cooling and reducing the pressure, the high-temperature steam will have a temperature or pressure that does not meet industrial needs, resulting in reduced work efficiency.

Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0015] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Although the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation, the form, quantity, positional relationship and proportion of each component in actual implementation can be changed at will under the premise of realizing the technical solution of this party, and the component layout form may also be more complicated.

[0016] Example

[0017] This embodiment provides an energy-saving and consumption-reducing device that replaces the temperature and pressure reducing device. Figure 1The device includes a steam turbine unit 1, a first stop valve 4 is provided at the front end of the steam turbine unit 1, and a pipeline group is provided at the rear end of the steam turbine unit 1, the pipeline group including a stop pipeline 3 and a pressure reducing pipeline 2; the stop pipeline 3 includes a second stop valve 301 and a check valve 302, one end of the second stop valve 301 is connected to the steam turbine unit 1, and the other end is connected to the check valve 302, and the other end of the check valve 302 is connected to other processes, the pressure reducing pipeline 2 includes a first coupling 201, a reduction box 202, a second coupling 203 and a circulating water pump 204, one end of the first coupling 201 is connected to the steam turbine unit 1, and the other end is connected to the reduction box 202, the other end of the reduction box 202 is connected to the second coupling 203, the other end of the second coupling 203 is provided with a circulating water pump 204, and the other end of the circulating water pump 204 is connected to other processes.

[0018] Still refer to the attached Figure 1 The device is also equipped with a temperature detector 6 and a pressure detection device 7. The temperature detector 6 is located between the steam turbine unit 1 and the second stop valve 301, and the pressure detection device 7 is located between the second stop valve 301 and the check valve 302. The temperature detector 6 is used to detect whether the temperature of the gas after cooling meets the production requirements, and the pressure detection device 7 is used to detect whether the pressure of the steam after decompression meets the production pressure requirements, thereby ensuring that the steam after cooling and pressure reduction can significantly improve production efficiency. A return pipe 5 is also provided at the rear end of the check valve 302. The other end of the return pipe 5 is connected to the steam turbine unit 1. A control valve 501 is also provided on the middle surface of the return pipe 5.

[0019] Still refer to the attached Figure 1 When the device is in use, high-temperature, high-pressure steam enters the steam turbine unit 1 through the first stop valve 4, circulates within the steam turbine unit 1, performs work, and drives the steam turbine unit 1 to rotate at high speed. The rotor of the steam turbine unit 1 transmits mechanical energy to the reduction gearbox 202 through the first coupling 201. The reduction gearbox 202 then transmits the mechanical energy to the circulating water pump 204 through the second coupling 203, converting the thermal energy of the steam into mechanical energy for the circulating water pump 204. After performing work in the steam turbine unit 4, the low-temperature, low-pressure steam passes through the temperature detector 6, the second stop valve 301, the pressure detection device 7, and the check valve 302 in sequence. When the low-temperature, low-pressure steam does not meet any of the production temperature and pressure requirements, the control valve 501 is opened, allowing the steam that does not meet the production requirements to re-enter the steam turbine unit through the return pipe 5 and undergo the temperature and pressure reduction process again to meet subsequent production needs. The steam that meets the temperature and pressure requirements enters other processes for use in subsequent production equipment processes.

[0020] To sum up, the utility model sets a cut-off pipeline and a pressure reducing pipeline at the rear end of the steam turbine unit. The pressure reducing pipeline includes a coupling, a reduction gearbox and a circulating water pump. It can effectively transfer high-temperature and high-pressure steam through the steam turbine unit to the coupling, the reduction gearbox and the circulating water pump, convert it into low-temperature and low-pressure steam, and transmit it to other devices, effectively reducing energy consumption loss, reducing the company's production and manufacturing costs, and maximizing the company's economic benefits.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
