The factories and miness of the main application scope of this utilize device of useless flue gas steam raising of high temperature for producing the useless flue gas of high temperature, the device can utilize the useless flue gas of the high temperature of emission to come the steam raising for the use through the heat exchange, have so both reduced useless flue gas to atmospheric thermal pollution, again recycle the energy, kill two birds with one stone, the device energy recuperation is efficient, and simple structure, low in cost, and it is convenient to maintain.
Description
Technical field
The utility model relates to a kind of device producing steam, especially relates to a kind of device utilizing high-temperature waste flue gas to produce steam.
Background technology
A lot of factories and miness all need to discharge useless flue gas in daily production process, and the temperature of these useless flue gases often very high (more than 200 DEG C), if directly drain into air, then both causes thermal pollution to air, waste energy again.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of device utilizing high-temperature waste flue gas to produce steam, be mainly used in the thermal energy that steam power plant reclaims high-temperature waste flue gas, both can reduce the thermal pollution of useless flue gas to air, and the thermal energy of high-temperature waste flue gas can have been utilized again to produce steam for use simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a kind of device utilizing high-temperature waste flue gas to produce steam, include heat exchanger, steam-water separator, the bottom of heat exchanger has gas approach, top has exhanst gas outlet, spiral channel group is provided with in heat exchanger, spiral channel group is communicated with steam-water separator by the inlet channel and carbonated drink discharge line being provided with intake pump, steam-water separator is provided with steam delivery line, Pressure gauge, thermometer, water gage, pressure relief safety valve and water pipe, small pump and flow control valve is provided with in water pipe.Each spiral channel surface that high-temperature waste flue gas enters in spiral channel group after in heat exchanger forms turbulent flow, and heat exchange efficiency is high, and strong backflow and eddy flow make each spiral channel surface less scaling.Steam water interface in each spiral channel enters steam-water separator through carbonated drink discharge line, and water vapour is discharged through the steam delivery line of steam-water separator, and water is stayed in steam-water separator for again recycling.The water pipe of steam-water separator is according to the water-holding quantity situation automatic water supplement in steam-water separator.
Say further, between the gas approach and exhanst gas outlet of heat exchanger, be provided with bypass pipe, be provided with volume damper in bypass pipe, carbonated drink discharge line is provided with temperature detector, and volume damper is connected with temperature detector by transmitter.The temperature detector that carbonated drink discharge line is arranged is for detecting the temperature of the steam water interface in carbonated drink discharge line, its signal sent converts the control action to volume damper to by transmitter, volume damper carrys out by regulating the flow of useless flue gas in bypass pipe the flow that indirect regulation flows through the useless flue gas of spiral channel group, thus reaches the control temperature of steam water interface, the object of assurance device safe operation.
The beneficial effects of the utility model are: this utilizes high-temperature waste flue gas to produce the main applicable situation of device of steam for producing the factories and miness of high-temperature waste flue gas, this device can utilize the high-temperature waste flue gas of discharge to produce steam for use by heat exchange, so both decreased the thermal pollution of useless flue gas to air, recycle again energy, killed two birds with one stone; This device energy recovery efficiency is high, and structure is simple, cheap, easy to maintenance.
