A direct supplementary pressure high temperature steam circulation system

Abstract

The invention discloses a direct-pressure-supplementing type high-temperature steam circulation system which comprises a water storage tank, a high pressure pump, a vaporizer, a high pressure buffer tank, a steam compressor, a temperature and humidity regulator, and a steam using unit. An inlet of the vaporizer is connected with an outlet of the water storage tank by the high pressure pump. An outlet of the vaporizer communicates with an inlet of the high pressure buffer tank. An outlet of the top of the high pressure buffer tank communicates with an inlet of the steam compressor. An outlet ofthe steam compressor communicates with an inlet of the temperature and humidity regulator. An outlet of the temperature and humidity regulator communicates with an inlet of the steam using unit. An outlet of the steam using unit communicates with the inlet of the high pressure buffer tank. An outlet of the bottom of the high pressure buffer tank communicates with the inlet of the vaporizer. According to the direct-pressure-supplementing type high-temperature steam circulation system, high pressure wet steam or superheated steam discharged from the steam using unit can be directly subjected totemperature and pressure increasing to the target high temperature and high pressure steam parameter at the inlet of the steam using unit, stored energy of mediums discharged from the steam using unit can be fully utilized, and significant energy-saving benefits are provided.

Description

technical field [0001] The invention belongs to the field of energy conservation and environmental protection, and relates to a high-temperature steam circulation system, in particular to a direct pressure-complementing high-temperature steam circulation system capable of realizing heat storage and recycling of high-temperature, high-pressure wet steam and superheated steam itself. Background technique [0002] As a high-quality heat source, high-pressure and high-temperature 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 ...
