An energy-saving high-pressure steam generator with cycle operation

Abstract

The invention discloses an energy-saving type high-pressure steam generating device operating in a circulating manner, and belongs to the field of energy conservation and environment protection. A high-pressure water tank is connected to an inlet of an ejector through a circulating pump. An outlet of the ejector is connected to a first inlet of a temperature and humidity regulator through a heater. An outlet of the temperature and humidity regulator is connected to an inlet of a steam using unit. An outlet of the steam using unit communicates with an inlet of a buffering tank. A bottom outletof the buffering tank is connected to an upper inlet A of the high-pressure water tank. A top outlet of the buffering tank is connected to a throat inlet of the ejector. The inlet end of a high-pressure pump is connected with a water supply device. A first branch of an outlet of the high-pressure pump is connected with an inlet of the heater. A second branch of the outlet of the high-pressure pumpis connected with a second inlet of the temperature and humidity regulator. High-temperature and high-pressure water or wet steam discharged out from the steam using unit is subjected to temperaturerise and pressure rise, converted into target high-temperature and high-pressure steam and sent back to the inlet of the steam using unit again, cyclic utilization of fluid discharged out from the steam using unit is achieved, the energy conservation and environment protection effect is obvious, and the energy-saving type high-pressure steam generating device can be widely applied to the field ofenergy conservation and environment protection.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection, and relates to a high-pressure steam generating device, in particular to an energy-saving high-pressure steam generating device capable of realizing recycling of high-temperature, high-pressure water and wet steam. Background technique [0002] As a high-quality heat source, high-temperature and high-pressure steam has been widely used as a heating medium for various heat exchange equipment and as a process medium in the petrochemical industry. In the field of heat exchange, when high-temperature and high-pressure steam is used as the heat source of the working medium to be heated at a relatively high temperature, after the heat source steam transfers part of its sensible heat, part or even all of its latent heat to the medium to be heated, its own temperature drops slightly or remains unchanged, and remains unchanged. It has a high temperature value; when the high-temper...
