Description
Technical field
The utility model relates to a kind of waste heat recovery machinery apparatus field, especially a kind of hot cigarette waste-heat recovery device that industrial and mining enterprises are produced because of burning.
Background technology
According to investigations, in the industrial furnace or boiler smoke of national every field, have 7%~15% sensible heat and approximately 10% latent heat just be not utilized and directly be discharged in atmosphere.According to the data demonstration of authoritative department issue, flue gas loss is one maximum in the every loss of boiler, generally is about 8%~15%, accounts for 60%~70% of boiler heat loss.The principal element that wherein affects flue gas loss is exhaust gas temperature.Generally, 10 ℃ of the every increases of exhaust gas temperature, heat loss due to exhaust gas increases by 0.6%~1%, corresponding many consumption coals 1.2%~2.4%, be becoming tight fossil energy day at present, under the overall situation that price constantly rises, fully universal boiler exhaust gas waste heat is utilizing technology, naturally just becomes one of effective way that realizes energy-saving and emission-reduction.
But recognize in the more current enterprise that applies flue gas waste heat recovery system, most of flue gas waste heat recovery system just simple before the dust-removing desulfurizing device of steam generator system mounting disc tubular air preheater or cigarette water interchanger, to boiler back end ductwork more than 150 ℃ high-temperature residual heat carry out limited recycling.Thereby ubiquity waste heat recovery inefficiency, the problem such as range of application is narrow, thus greatly reduce user's transformation enthusiasm.
And the heat energy that reclaims is all generally directly to remove to heat cold water, produces a large amount of hot water, but this hot water is slatterned in a large number, according to the hot water with not only so many.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of flue residue heat recovery utilization rate high, to the heat recovery rate in flue gas at least at 60% device for recovering residual heat of flue.
The scheme of device for recovering residual heat of flue of the present utility model is design like this, it comprises the flue heat recover, the flue heat recover is the hollow box body of a sealing, the head of the hollow box body of sealing is provided with into mouth, and the afterbody of the hollow box body of sealing is provided with outlet flue, also be provided with many parallel metal tubes in the hollow box body of sealing, by bend pipe, they are connected to form an oil pipe in twos between metal tube, the hollow box body of sealing is extended at the two ends of oil pipe, one end of oil pipe is oil-in, and the other end of oil pipe is oil-out.
For the heat energy that makes flue heat recycling device can fully effectively utilize, can supplying energy while needing simultaneously, not energy supply when not required, therefore, flue heat recycling device described above can also comprise the heat accumulation buffer, the heat accumulation buffer is the container of a sealing, be provided with conduction oil in container, the heat accumulation buffer is connected by tube connector with the two ends of an oil pipe of flue heat recycling device, make the closed circuit that forms a conduction oil between the oil pipe of flue heat recycling device and heat accumulation buffer, tube connector is provided with pump and check valve simultaneously; Also be provided with external interface on the heat accumulation buffer, this external interface is oil-in and oil-out, and this external interface is in order to make, the thermal energy exchange that stores in conduction oil in the heat accumulation buffer to be gone out.
In order to fix a breakdown, be convenient to plant maintenance, be provided with the access door of personnel's turnover in the hollow box body of sealing.
In order to increase endothermic effect, according to being provided with sheet metal on every metal tube in the hollow box body of above-described sealing; Certainly sheet metal can be also the part setting, and sheet metal is spiral and is fixed on every metal tube; Can certainly be that sheet metal is plates, the multi-disc sheet metal be enclosed within on every metal tube simultaneously, increases the endotherm area of pipe; On the hollow box body of sealing, many parallel metal tubes are many row's arrangements, front-seat metal tube and rear row's metal tube are staggered and arrange, make the pipe layout in hollow box body evenly reasonable, can be absorbed by the conduction oil in metal tube to the greatest extent through the heat in the flue gas of metal tube, then be transported in the energy storage buffer.
The heat accumulation buffer also is connected with the mechanism of demand heat energy by an other road binders pipe with oil-out by the oil-in on it,, as with water tank, being connected, can provide hot water; Also can be connected with heat-exchanging air conditioner, reach the heating purpose.
The flue gas waste heat recovery apparatus of the current research and development of our company, approximately 60%~85 heat effectively reclaims in reality test can be with flue gas, exhaust gas temperature can drop to below 100 ℃, thereby improves the whole operation of boiler efficiency 8%~15%, to reforming enterprise, brings considerable economic benefit.
According to statistics, there are 500,000 of Industrial Boilers in China, and total capacity reaches 1,800,000 and steams ton/time.To produce 130 kilograms, steam consumption mark coal per ton, 54% calculating of boiler operatiopn rate, the standard coal that annual Industrial Boiler consumes is up to 1,100,000,000 tons.The every raising 1% of boiler thermal output, just can save 1,100 ten thousand tons, mark coal, reduces more than 4,000 ten thousand tons of CO2 emissions, and economic benefit and environmental benefit are remarkable.Therefore, the utlity model has energy savings, protection of the environment, the characteristics such as simple in structure.
