Description
Technical field
The utility model relates to residual heat using device, is specifically related to a kind of cogeneration units residual heat using device.
Background technology
Violent typhoon, sandstorm, high temperature and drought, Extreme Precipitation, in recent years, global extreme weather is shown effect again and again, endangers serious all the more.Trace it to its cause, wherein most important and human bear bounden responsibility be, carbon-based fuel consumes excessive and global warming that cause, extreme weather is a refraction of energy resource consumption problem.
Investigation of the Chinese Academy of Sciences shows that China is one of the most serious country of whole world natural resources waste, and rank is the 56th in 59 countries that accept to investigate.According to another statistics, the energy use efficiency of China is merely 26.9% of the U.S., 11.5% of Japan.Therefore, advancing energy-saving and emission-reduction, is extremely urgent.
Waste heat is under certain economic technology condition, the energy that in using energy source equipment, is not utilized.Just unnecessary, the discarded energy.It comprises high-temp waste gas waste heat, cooling medium waste heat, waste vapour waste water residual heat, high-temperature product and afterheat of slags, chemical reaction waste heat etc.According to investigation, the waste heat total resources of every profession and trade account for 17% ~ 67% of its fuel consumption total amount, and the residual heat resources of recyclable utilization are about 60% of waste heat total resources.Therefore, waste heat recovery can be used as effective ways implementing energy-saving and emission-reduction.
Summary of the invention
The purpose of the utility model is: a kind of cogeneration units residual heat using device is provided, adopts this residual heat using device to cogeneration units
Waste heat recycle, promptly utilize the waste heat of thermoelectric unit to add hot water, externally supply with hot water, like this, both reduced pollutant emission, improve enterprise efficiency again, reduce coal consumption.
The technical solution of the utility model is: this residual heat using device comprises waste heat collector, waste-heated water-tank, ultrafiltration water tank and cooling tank; Two pipeline delivery pumps are installed on the ultrafiltration water tank outlet conduit water is delivered to the waste heat collector; Boiler afterheat is hydrophobic draws a pipeline as mother's pipe and mounted valve through threeway; Be divided into two branch roads behind the valve and go waste heat collector and waste-heated water-tank respectively; And valve all is housed on two branch roads, and boiler soot-blowing is hydrophobic, electric precipitation insulation is hydrophobic, desulfurization GGH blows that ash is hydrophobic directly to be connected to the waste heat collector through drain water piping, and the outlet pipe of waste heat collector is communicated with the waste-heated water-tank; Cooling tank is communicated with the waste-heated water-tank through tubing pump, and waste-heated water-tank's outlet pipe is transported to externally supply in the water-tank lorry through tubing pump.
Wherein, the heat supply pipeline of cogeneration units is drawn a pipeline and is communicated with the waste-heated water-tank as standby heat source, and stop valve and manual modulation valve are installed on pipeline.
The utlity model has following advantage:
1, the waste heat collector plays the intermediate water tank effect when collecting boiler afterheat, and can make hot water be able to deposition.
2, at the waste heat collector sewage draining exit is set, periodical blowdown guarantees that water quality is good.
3, the waste-heated water-tank receives water tank as the hot water of waste heat collector, is transported to external hot-water supply in the water-tank lorry through tubing pump at last.
4, boiler afterheat is hydrophobic not only can flow into the waste heat collector but also can directly cut the waste-heated water-tank; Guarantee the stable supply of hot water; During normal the operation, the hydrophobic whole inflow waste heat collectors of boiler afterheat are being transported to the waste-heated water-tank at the waste heat collector through heat exchange, post precipitation again.
5, the heat supply pipeline of cogeneration units is drawn a pipeline connection waste-heated water-tank as standby heat source, and stop valve and manual modulation valve are installed on pipeline, guarantees waste-heat recovery device stable operation; Guarantee external supply water temperature, raise, do not influence the cogeneration units safe and stable operation through control valve regulate steam flow calorimetric coolant-temperature gage is stable;, water temperature closes stop valve after reaching requirement; During normal the operation (supply water temperature meets the demands), valve closing is when waste-heated water-tank's water temperature is lower than external supply water temperature; Open valve, heat hot water.
6, the UTILIZATION OF VESIDUAL HEAT IN of cogeneration units has been avoided the self-built arcola of some enterprises, and arcola efficient is calculated by 80% at present, and this waste heat recovery is equivalent to practice thrift every day 5t mark coal, and so annual coal conservation reaches 1500 t.
7, one ton of standard coal of the every burning of arcola just produces 2620 kilograms of carbon dioxide; 8.5 kilograms of sulfur dioxide; 7.4 kilograms of nitrogen oxide, UTILIZATION OF VESIDUAL HEAT IN can not only reduce the thermal pollution discharging, also can reduce SO2, NOx and CO2 rafting simultaneously; Alleviate the pressure of environment, annual SO2, NOx and the CO2 discharge capacity of reducing of waste heat recovery sees the following form.
| ? | SO2 | NOx | CO2 |
| CER (t/a) | 23.2 | 20.3 | 7176.1 |
