Abstract
The utility model relates to a flue gas waste heat recovery device, which comprises a drum and a smoke chamber. A heat pipe is vertically fixed in the drum and the smoke chamber, two thirds of the heat pipe is arranged in the drum, one third of the heat pipe is arranged in the smoke chamber, and the drum is also provided with a water inlet, a steam outlet and a safety valve. The flue gas waste heat recovery device is mainly matched with an industrial furnace or an industrial boiler foe use to reduce losses caused by flue gas emissions of the boiler, and the heat losses can be recycled so as to help to meet the requirements of environmental protection and energy conservation advocated at present.
Description
Technical field
The utility model relates to the steam generator technical field, especially refers to a kind of flue gas waste heat recovery apparatus.
Background technology
The flue gas of Industrial Stoves and Industrial Boiler does not process, and directly drains into atmosphere, only causes environmental pollution; Wasted a large amount of energy again, the utility model flue gas waste heat recovery apparatus mainly is the supporting use that is used for Industrial Stoves and Industrial Boiler; In order to reduce the loss that the boiler smoke discharging is caused; This partial heat energy loss is recycled, is beneficial to present environmental protection and the energy-saving and emission-reduction requirement of being advocated, have following characteristics:
1. easy for installation: heat pipe-type waste-heat recovery device volume is little, and compact conformation is installed and need do not changed former boiler or Industrial Stoves,
2. safe and reliable: super heat-conductive pipe isothermal performance is good, and producing self-vibration during heat conduction, not produce stifled ash little with flowing resistance, remains good heat transfer efficient, adopting heat pipes for heat transfer operating safety factor height, and the damage of single heat pipe does not influence the safe operation of entire equipment,
3. long service life: the super heat-conductive pipe heat recovery steam generator safeguards that normally more than 10 years simple cost is low service life,
4. energy-saving benefit is good: the large-sized industrial kiln thermal efficiency can improve more than 10%, and middle-size and small-size fuel oil, combustion gas and the coal-burning boiler thermal efficiency can improve 5%～10%, and reduces toxic emission and improve environmental pollution.
Summary of the invention
The purpose of the utility model is to provide a kind of flue gas waste heat recovery apparatus, and partial heat energy is recycled.
The present following technical scheme of passing through of the utility model realizes: a kind of flue gas waste heat recovery apparatus; Form by drum and smoke-box; Heat pipe is vertically fixed on the inside of drum and smoke-box; Heat pipe 2/3rds in drum, 1/3rd in smoke-box, also is provided with water inlet, steam (vapor) outlet, safety valve on the drum.Through repeatedly experiment, heat pipe 2/3rds is in drum, and 1/3rd in smoke-box, and energy recovery is most effective.
Also include inspection opening on the preferred drum, the convenient observation keeped in repair.
Also include Pressure gauge on the preferred drum, prevent that the drum internal pressure is excessive.
Also include liquid level gauge on the preferred drum, observe the height of water.
In order to improve quality of steam, water dust scrubber can be installed above in drum, to filter the moisture in the steam.
The beneficial effect of the utility model, 1, easy for installation: heat pipe-type waste-heat recovery device volume is little, and compact conformation is installed and need do not changed former boiler or Industrial Stoves.2, safe and reliable: super heat-conductive pipe isothermal performance is good, and producing self-vibration during heat conduction, not produce stifled ash little with flowing resistance, remains good heat transfer efficient, adopting heat pipes for heat transfer operating safety factor height, and the damage of single heat pipe does not influence the safe operation of entire equipment.3, long service life: the super heat-conductive pipe heat recovery steam generator safeguards that normally more than 10 years simple cost is low service life.4, energy-saving benefit is good: the large-sized industrial kiln thermal efficiency can improve more than 10%, and middle-size and small-size fuel oil, combustion gas and the coal-burning boiler thermal efficiency can improve 5%～10%, and reduces toxic emission and improve environmental pollution.
