Abstract
The present invention is a kind of MGGH system of composite phase-change heat exchange, evaporator section heat exchanger, desulfurizing tower, condensation segment heat exchanger composition.High-temperature flue gas passes sequentially through evaporation and heat-exchange section, desulfurizing tower, condensation segment heat exchanger, the heat that evaporator section heat exchanger absorbs flue gas generates steam, it is transmitted in condensation segment heat exchanger naturally by density contrast, flue gas is heated in heat release in condensing heat exchanger, and steam becomes condensed water return evaporator section heat exchanger and re-starts heat absorption, forms a closed cycle.In the case where tail flue gas temperature meet demand, the vapor portion of generation can be supplied to other processes, while the supplement of demineralized water is carried out to evaporator section heat exchanger.The phenomenon that phase-change heat-exchange can effectively control the wall temperature of heat exchanger, prevent low-temperature corrosion.Extra steam can supply other processes, while realizing MGGH, realize the depth waste heat recycling of flue gas.
Description
Technical field
The present invention relates to field of environment engineering technology, the MGGH of especially a kind of composite phase-change heat exchange and waste heat recycling system
System.
Technical background
Currently, the industries such as China's steel, papermaking, electric power, which are widely used, carries out again flue gas in order to administer wet plume problem
The processing method of heat, and common MGGH system low-temperature corrosion in order to prevent, are limited to cooling extent, there are fume afterheats can not
Meets the needs of heating.
Summary of the invention
The present invention is a kind of MGGH system of composite phase-change heat exchange, evaporator section heat exchanger, desulfurizing tower, condensation segment heat exchanger group
At.High-temperature flue gas passes sequentially through evaporation and heat-exchange section, desulfurizing tower, condensation segment heat exchanger, the heat of evaporator section heat exchanger absorption flue gas
Steam is generated, is transmitted in condensation segment heat exchanger naturally by density contrast, flue gas is heated in heat release in condensing heat exchanger, and steam becomes
Evaporator section heat exchanger is returned for condensed water and re-starts heat absorption, forms a closed cycle.When tail flue gas temperature meet demand
In the case where, the vapor portion of generation can be supplied to other processes, while the supplement of demineralized water is carried out to evaporator section heat exchanger.
It is further described that evaporator section heat exchanger and condensation segment heat exchanger are arranged in the front and back of desulfurizing tower.
It conducts heat it is further described that selling of one's property raw steam as heating agent using water phase, realizes MGGH system.
It is further described that evaporator section heat exchanger and condensation segment heat exchanger form natural cycle system.
It is further described that the extra heat of evaporator section heat exchanger supplies other processes as a vapor.
The beneficial effects of the present invention are: phase-change heat-exchange can effectively control the wall temperature of heat exchanger, showing for low-temperature corrosion is prevented
As.Extra steam can supply other processes, while realizing MGGH, realize the depth waste heat recycling of flue gas.
Detailed description of the invention
Invention invention is further described with reference to the accompanying drawings and detailed description.
Attached drawing 1 is the MGGH and residual neat recovering system schematic diagram of a kind of composite phase-change heat exchange；
In figure: 1, evaporator section heat exchanger, 2, desulfurizing tower, 3, condensation segment heat exchanger.
Specific embodiment
As shown in attached drawing, the MGGH and residual neat recovering system of a kind of heat exchange of composite phase-change are by 1, evaporator section heat exchanger, and 2, de-
Sulphur tower, 3, condensation segment heat exchanger composition；When the system is run, high-temperature flue gas enters desulfurizing tower 2 by evaporator section heat exchanger 1,
Later by being discharged into atmosphere after condensation segment heat exchanger 3.The heat that wherein evaporator section heat exchanger 1 absorbs flue gas generates steam,
It is transmitted in condensation segment heat exchanger 3 naturally by density contrast, flue gas is heated in heat release in condensing heat exchanger 3, and steam becomes condensing
Water returns to evaporator section heat exchanger and re-starts heat absorption, forms a closed cycle.When the tail flue gas temperature meet demand the case where
Under, the vapor portion of generation can be supplied to other processes, while the supplement of demineralized water is carried out to evaporator section heat exchanger.
The above, embodiment is only that preferred embodiments of the present invention will be described, not to of the invention
Range is defined, and under the premise of not departing from the spirit of the technology of the present invention, this field engineers and technicians are to skill of the invention
The various changes and improvements that art scheme is made, should fall within the scope of protection determined by the claims of the present invention.
