Multifunctional ejector

Abstract

The invention relates to a multifunctional ejector. The multifunctional ejector comprises a main body pipe, a nozzle, a steam inlet pipe, a diffusing pipe and an ejecting pipe, wherein an intake port communicating with the inner cavity of the main body pipe is arranged at the lower end of the main body pipe; a door body sealing the front end of the main body pipe is arranged at the front end of the main body pipe; the door body is detachably connected with the front end of the main body pipe; the nozzle is horizontally arranged in the main body pipe; the steam inlet pipe penetrates through the door body from the outside, stretches in the main body pipe and hermetically communicates with the front end of the nozzle; the steam inlet pipe is capable of driving the nozzle to horizontally move to the front and rear; the diffusing pipe is fixedly arranged at the rear end of the main body pipe and communicates with the main body pipe; the ejecting pipe is fixedly arranged at the rear end of the diffusing pipe and communicates with the diffusing pipe; a scale groove is arranged in a pipe body at one side away from the main body pipe, of the steam inlet pipe; and a clip capable of clamping the steam inlet pipe is arranged on the door body. According to the multifunctional ejector disclosed by the invention, the position of the nozzle in the main body pipe can be adjusted, thus the working efficiency is increased, the cost is reduced, the system stability is ensured, energy waste is reduced, and high regulation and control accuracy is achieved.

Description

technical field [0001] The invention relates to a multifunctional injector. Background technique [0002] The ejector is a simple device for boosting the pressure of low-pressure steam through high-pressure steam. It mainly uses the energy exchange between high-pressure steam and low-pressure steam to achieve the purpose of boosting the pressure of low-pressure steam. The device has the characteristics of simple structure, small investment, reliable operation, high thermal efficiency, energy saving, and environmental protection. [0003] At present, the steam injectors used in domestic production must perform heat exchange and produce mixed steam under the condition of constant driving steam pressure, so it is necessary to design different nozzle positions, that is, the relative positions from the nozzle outlet to the mixing chamber inlet , to meet different actual industrial driving steam pressures, which leads to the use of new steam injectors with specific parameters due...

Problems solved by technology

[0003] At present, the steam injectors used in domestic production must perform heat exchange and produce mixed steam under the condition of constant driving steam pressure, so it is necessary to design different nozzle positions, that is, the relative positions from the nozzle outlet to the mixing chamber inlet , to meet different actual industrial driving steam pressures, which leads to the use of new steam injectors with specific parameters due to changes in working conditions, which increases production costs and also makes it impossible to use high-pressure steam with unstable pressure as Drive steam, poor adjustable performance, and poor regulation accuracy
