[0003]
Industrial production often requires steam of several different pressure levels, but the steam pressure provided by the boiler is generally relatively single. Now the common way to use it is to reduce the temperature and pressure of the steam, which will cause invalid depreciation of heat energy and loss of heat exergy. Exergy loss is a measure to measure the rational utilization of steam
[0004]
At present, there is no way to heat softened water with steam in a jet method, and then heat water with flue gas in a heat exchange method to convert it into steam, and then inject low-pressure steam with high-pressure steam in a jet-flow method to increase the pressure, and make reasonable use of steam surplus pressure. Flue gas waste heat recovery equipment supplied to users according to steam pressure level

The invention discloses a steam boiler heat exchange unit capable of recycling waste heat to increase production and efficiency, and relates to a steam boiler heat exchange unit. The heat exchange unit comprises an evaporation type finned tube heat exchanger, a jet type steam-water mixing heater and a jet type steam compression pump. Accord to the unit integrated by taking the evaporation type finned tube heat exchanger, the jet type steam-water mixing heater and the jet type steam compression pump as main single unit, the use of boiler flue gas waste heat to heat softened water to enable thesoftened water to generate phase change and be converted into steam is realized through the cooperation of respective functions, and the new steam excess pressure is reasonably used to achieve the purpose of energy conservation. The steam boiler heat exchange unit recycles the boiler flue gas waste heat, increases the steam supply capacity of a boiler, improves the heat efficiency of the boiler, and is small in size, convenient to install and stable and reliable in operation.
Description
technical field [0001] The invention relates to a steam boiler heat exchange unit, in particular to a steam boiler heat exchange unit capable of recovering waste heat to increase production and efficiency. Background technique [0002] According to the way of heat transfer and utilization of flue gas, the existing waste heat recovery equipment related to steam boiler flue gas that has been used mainly includes two categories. The first type is surface heat exchange equipment that does not contact the flue gas with the heat exchange medium, such as: Finned tube heat exchangers for preheating combustion air, heat pipe heat exchangers for heating air or water, etc. These heat exchangers mainly recover waste heat from flue gas in the form of heat conduction. The second category is heat exchange equipment in which the flue gas is in direct contact with the medium, such as: spray heat exchangers, cooling towers, gas condensers, etc. This type of heat exchanger mainly recovers the ...
