Abstract
The invention discloses a novel flue gas waste heat recycling device, which comprises a flue inlet, a flue outlet, a cold air inlet, a hot air outlet, a shell pass, a partition, a water inlet header, a water outlet header and heat exchange tube components. The water inlet header and the water outlet header are located at the top and bottom of the shell pass respectively, and are connected by the heat exchange tube components which are located in the shell pass. The outside of the shell pass is connected with the flue inlet, the flue outlet, the hot air outlet and the cold air inlet. The shell pass is divided into a flue gas passage and an air passage by the partition, so that the manufacturing of the outside shell of the traditional heater is omitted, the steel consumption is lowered, and the manufacturing cost is reduced. Airtight chambers are arranged outside the heat exchange tube components, and each of the airtight chambers is half full of superconductive liquid and half vacuum, so that the air and the water can absorb heat at the same time, the heat exchange effect is good, and the whole efficiency is improved. By the novel flue gas waste heat recycling device, cost of manufacturing, transportation, installation and management is reduced, and resources are saved greatly for the society.
Description
Technical field
The invention belongs to energy-saving environmental protection device technical field, relate to a kind of Novel flue gas waste-heat recovery device.
Background technology
At present, the various residual heat using device such as air preheater, water heater are widely used in the flue gas afterbody of the industrial products such as various stoves, kiln, so that Mist heat recovering, reduce energy loss, save the energy, the flue gas afterbody of a lot of industrial products is installed must install again the water heater waste heat in recovered flue gas completely after air preheater, prior art produce hot-air and produce hot water by two independently equipment complete.Air preheater is the energy-saving equipment that reclaims waste heat of flue gas of heating furnace, there is various structures form: heat pipe-type, light pipe type, fin tube type, strengthening tubular type, swinging, these patterns respectively have pluses and minuses, heat exchange efficiency is relatively low, and the cost of manufacturing, transport, install, managing can increase, make the fume afterheat utilization of industrial products be difficult to popularize, cause a large amount of wastes of resource.
Summary of the invention
The waste heat utilization equipment that the object of the invention is to solve prior art can not produce hot-air and hot water, technical barrier that heat exchange efficiency is low simultaneously.Provide a kind of and can enter to produce hot-air and can produce again hot water, Novel flue gas waste heat recovery apparatus device that heat exchange efficiency is high, thereby increase work efficiency, reduce manufacture, transportation, installation, management cost.
The present invention is that the technical scheme that solves the problems of the technologies described above employing is:
A kind of Novel flue gas waste-heat recovery device, by entering mouth, outlet flue, inlet of cold air, hot air outlet, shell side, dividing plate, water inlet header, water outlet header, heat exchange tube assemblies, form, it is characterized in that: described water inlet header is positioned at shell side top, water outlet header is positioned at shell side bottom, and water inlet header, water outlet header are connected by the heat exchange tube assemblies that is positioned at shell side inside; Shell side outside is connected to into mouth, outlet flue, hot air outlet and inlet of cold air.
Dividing plate is divided into exhaust gases passes and air duct by shell side.
Heat exchange tube assemblies outside has airtight cavity, and airtight cavity contains the superconducting fluid of half, and second half is vacuum.
Beneficial effect of the present invention is, Novel flue gas waste-heat recovery device is compared with water heater with traditional air heat exchanger, because the main heating part of traditional water heater is built in shell side inside, reduced the making of the external shell of traditional water heater, steel quantity consumption is few, improve production efficiency, reduced cost of manufacture; Internal heat exchange tubes contains superconducting fluid, and water and air can be absorbed heat simultaneously, and good effect of heat exchange, has improved overall efficiency.The use of Novel flue gas waste-heat recovery device, makes to have reduced by an equipment in flue gas afterbody residual neat recovering system, has shortened installation period, has reduced floor space, has reduced management cost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
In figure: 1, enter mouth 2, dividing plate 3, hot air outlet 4, water inlet header 5, heat exchange tube assemblies 6, inlet of cold air 7, outlet flue 8, superconducting fluid 9, water outlet header, 10 shell sides, 11 airtight cavities.
The specific embodiment
With reference to accompanying drawing, it comprises the 4 water inlet headers that are positioned at 10 shell side tops the present invention, what be connected with 4 water inlet headers is 5 heat exchange tube assemblies that are positioned at 10 shell side inside, outside 11 airtight cavities of 5 heat exchange tube assemblies contain 8 superconducting fluid of half, second half is vacuum, what 5 heat exchange tube assemblies bottoms connected is 9 water outlet headers, and 10 shell side outsides are connected to 1 and enter mouth, 7 outlet flues, 3 hot air outlets and 6 inlet of cold airs, and 2 dividing plates are divided into exhaust gases passes and air duct by 10 shell sides.
Operation principle of the present invention: high-temperature flue gas enters mouth from 1 and enters 10 shell side inside, wash away fast 5 heat exchange tube assemblies, the outside airtight cavity of 5 heat exchange tube assemblies 11 contains 8 superconducting fluid of half, second half is vacuum, 8 superconducting fluid are positioned at the bottom of 5 heat exchange tube assemblies, the heat of high-temperature flue gas is passed to 8 superconducting fluid in outside 11 closed cavities of 5 heat exchanger tubes, and flue-gas temperature reduces rapidly and discharges from 7 outlet flues.8 superconducting fluid absorb a large amount of heat volumes and expand rapidly and move upward, 8 superconducting fluid are passed to heat from 4 water inlet headers and are flow to the cold water that 5 heat exchange tube assemblies are inner and flow downward simultaneously, cold, hot fluid counter-current flow, strengthened heat transfer effect, improved heat exchange efficiency, cold water absorbs a large amount of heats and becomes hot water, and enter 9 water outlet headers and flow out extraneous, last 8 superconducting fluid are full of the top of outside 11 airtight cavities of 5 heat exchange tube assemblies, the cold air now coming from the outside enters 10 shell side tops from 6 inlet of cold airs, high speed cold air washes away 5 heat exchange tube assemblies, and absorb rapidly the heat of 8 superconducting fluid of the inside, top of outside 11 airtight cavities of 5 heat exchange tube assemblies, after a large amount of heat absorptions, cold air heats up and becomes the hot-air that meets instructions for use rapidly, and discharge from 3 hot air outlets.After a large amount of heat releases of 8 superconducting fluid of the inside, top of 5 heat exchange tube assemblies 11 outside airtight cavities, volume diminishes rapidly, because Action of Gravity Field drops to the bottom of 5 heat exchange tube assemblies, so move in circles, make 8 superconducting fluid constantly absorb in a large number the heat of high-temperature flue gas and heat is passed to cold water and cold air simultaneously, generate the hot water and the hot-air that meet instructions for use.
Flue gas waste heat recovery apparatus of the present invention, produces hot-air and produces hot water simultaneously, is different from traditional a kind of equipment and can only plays a kind of effect, improved operating efficiency, alleviate labour intensity, reduced the cost of manufacture, transportation, installation, management, for society has saved a large amount of resources.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
