Description
Technical field
The invention patent relates to a kind of heating systems using fume afterheat, especially a kind of to be led in garbage incinerating power plant
The heating system of the flue gas waste heat recovery in domain.
Background technology
Currently, the garbage burning boiler flue gas of City Life Trash Power Plant (hereinafter referred to as " garbage power plant ") passes through
After purification (about 130-150 DEG C), arranged from chimney to air, later with the cold air combination cooling in air, the heat in flue gas
It is directly taken away by air and is dispersed into air and wastes.
Invention content
This heating system is erected on chimney, and using row to the flue gas heat before air, heat hot water is realized by hot water
External heat supply.
This heating system is made of smoke heat exchanging system, water storage system and control system.
Smoke heat exchanging system uses rounded cylindrical structure, mating with Diameter of chimney, is erected on chimney.This heat exchanger uses
Core structure, the heat for recycling chimney breast flue gas.Ring Inlet and outlet water header is respectively adopted up and down in heat exchanger, heat exchanger tube it
Between by fin be connected, formed heat exchange barrel.To increase heat exchange surface area, heat exchanger tube is using ellipse.Heat exchanger internal diameter and cigarette
Chimney internal diameter is identical, does not influence flue gas flow rate.To be anticorrosive, heat exchanger is integrally made of 2205 two phase stainless steels.Outside heat exchanger
The heat-preservation cotton heat preservation of the forms such as alumina silicate can be used.Cold water enters from heat exchanger lower header, and heat is heated by barrel heat exchanger tube
It is confessed from upper collecting chamber after water.
Water storage system uses integrated form water tank：It is divided into hydrothermal area, cold water area and intermediate heating zone composition.According to current rubbish
Rubbish power plant actual conditions, since there are larger fluctuations with flue gas flow for chimney emission temperature, in order to ensure heating water's mass,
This system uses subregion integrated form hot water storage tank.For buffering and storing cold water, the cold water of cold water area, which is introduced into, to be added for cold water area
Hot-zone, heating zone water are controlled by water-level gauge, and after heating zone water level is filled it up with, the water of heating zone enters cartridge type heat exchange by water pump
Device circulating-heating, until temperature rises to 95 DEG C (heating temperature can be set by control panel), the hot water after heating is made
Enter hydrothermal area for finished product and externally carries out heat supply.The water of cold water area is carrying out moisturizing to heating zone simultaneously.
Control system uses PLC controller, and control is adjusted according to coolant-temperature gage in water storage system water level and water tank.Storage
It is kept the temperature using the heat-preservation cotton of the materials such as alumina silicate outside water pot, to ensure hot water quality.Water pump, valve, thermometer, water-level gauge
Etc. measuring instrumentss enter PLC control system, it can be achieved that automatically controlling.

Specific implementation mode
130-150 DEG C of flue gas, by the heat exchanger of chimney breast, the water in heating heat exchanger, hot water is defeated by water pipe
It is sent in hot water tank, water tank is placed on ground, is sent outside hot water by hot water pipeline or Hot water car.
