Background technology
Energy-conserving and environment-protective are the key subjects of China's research all the time, and boiler is a requisite thermal powerplant in Chinese national economy and the people's lives, add up according to interrelated data, whole nation active boiler adds up to more than 50 ten thousand, and it is discharged flue gas institute heat content and accounts for about the 10-15% of boiler total heat consumption, and how this part waste heat of research and utilization is very important, the subject matter that this current just boiler exists, be that boiler thermal output is low, exhaust gas temperature height, dust, pollutant major reason how in the cigarette.Not only high-temperature flue gas is taken away a large amount of waste heat energy, and dust concentration and harmful foreign material concentration of emission seriously surpass national environmental standard, cause air pollution, acid rain etc. takes place, severe exacerbation city people's quality of air environment, come current research personnel's key subjects for this improvement to the recovery of residual heat from boiler fume and flue gas noxious pollutant.Exhaust gas temperature is looked hot-water boiler with steam boiler and different, generally about 150 ℃-250 ℃, have a large amount of damp and hot and latent heat in the flue gas that is discharged from, thereby the cigarette temperature is dropped to below 100 ℃ by 150 ℃-250 ℃, the damp and hot and latent heat that reclaims in its flue gas has considerable economic value.
Summary of the invention
The purpose of this utility model is, designs a kind of floating disc cast residual heat from boiler fume retracting device, utilizes the heat exchange of floating coiled pipe, with flue gas waste heat recovery, improves the thermal efficiency of boiler.
The technical solution of the utility model is, a kind of floating disc cast residual heat from boiler fume retracting device, comprise the floating coiler heat exhanger that is arranged on the boiler smoke pipeline, this floating coiler heat exhanger is by housing, floating coiled pipe, be heated cold water turnover main, the flue gas inlet and outlet piping is formed, heat exchanger shell is tubular, in heat exchanger shell, be provided with minor diameter thin wall stainless steel or copper tube spirality polydisc floating coiled pipe, being heated cold water turnover main is connected with every dish floating coiled pipe intake-outlet respectively, the flow of flue gas direction of polydisc floating coiled pipe and boiler pipe is perpendicular, heat exchanger shell is provided with and is heated cold water and advances, the outlet short tube, and be connected with the Inlet and outlet water main that is connected of floating coiled pipe in the heat exchanger shell respectively, condensation sewage discharge pipe be provided with at the heat exchanger bottommost.
This heat exchanger polydisc floating coiled pipe is connected with the boiler exhaust gas pipe level, or is connected with the boiler exhaust gas pipeline is vertical.
The floating disc cast residual heat from boiler fume retracting device that the utility model proposes, the high-temperature flue gas that boiler is discharged is flowed through and is respectively arranged the floating coiled pipe group in the heat exchanger, carry out exchange heat with the water in the coil pipe, high-temperature flue gas is emitted heat and is lowered the temperature, and the cold water in the coil pipe is added behind the heat absorption heat by flue gas and heat up, flue gas by floating coiler heat exhanger after flue-gas temperature reduce to below 100 ℃ from 150 ℃~250 ℃ by heat release, damp and hot and latent heat in the flue gas is fully reclaimed, and during flue gas condensing in the water-soluble steam condensed water of wherein a part of harmful substance, this waste water can discharge after treatment, thereby can reduce the pollution to atmosphere.Therefore this device has not only utilized the waste heat in the boiler smoke, generally can improve the thermal efficiency 5%~15% of boiler, and help environmental protection.And in the heat exchanger cold water in the coil pipe by the flue gas heat temperature raising after, can be used for boiler replenishing water, the moisturizing of heating system hot water, life is with the usefulness of hot water bathing.
This floating coiled pipe residual heat from boiler fume retracting device also has following advantage: 1. flue gas is by behind the floating disc cast flue gas waste heat recovery apparatus, drag losses is little, in its flue gas resistance loss Hf<100mm water column, thereby shouldn't set up air exhauster on the boiler smoke pipeline, utilize burner for gas boiler pressure can satisfy the requirement of flue gas pressures exhaust, can keep original gas fired-boiler running status constant; 2. adopt stainless steel or copper tube coil, long service life, can reach more than 15 years, because stainless steel or copper tube smooth surface, ash and dirt are difficult for adhering to from the teeth outwards, can improve heat transfer efficiency, but floating coiled pipe disturbance in heat exchanger shell besides, make laminar flow become turbulent flow, can improve whole heat exchange efficiency; 3. can make full use of original boiler exhaust gas pipeline, save the purpose that investment is installed thereby can reach.The utility model is applicable to the residual heat from boiler fume retracting device.
