Abstract
The utility model discloses a high-temperature flue gas afterheat recovery device. The high-temperature flue gas afterheat recovery device comprises a shell, a high-temperature flue gas inlet, a flue gas channel, a tail gas outlet, a fan, a flue connected with the fan, a heat conducting fin group connected with the flue, a hot air outlet connected with the flue, a thermocouple positioned in the flue gas channel, and a control system outside the shell. In the way, by the adoption of the high-temperature flue gas afterheat recovery device, heat in high-temperature industrial tail gas can be absorbed effectively; the resource utilization rate is improved greatly; and energy source is greatly saved.
Description
Technical field
The utility model relates to high-temperature tail gas and reclaims the field, particularly relates to a kind of device for recovering waste heat of high-temperature flue.
Background technology
Because China is in industrialization and the stage is accelerated development in urbanization, energy resource consumption intensity is higher, and the consumption scale constantly enlarges, and the Extensive Economic Growth Mode of particularly high investment, high flow rate, high pollution has aggravated energy availability and demand contradiction and environmental situation.Energy problem has become the key factor of restriction economy and social development, fully realize the importance of carrying out working energy from the height of strategy and the overall situation, pays much attention to energy security, realizes the sustainable development of the energy.
Each cauldron factory of the whole nation is at industrial fuel oil, combustion gas, when coal-burning boiler manufactures and designs, because a variety of causes causes the specified thermal efficiency of boiler can only reach below 75%, especially the Industrial Stoves thermal efficiency is lower, only has heat energy more than 25% by flue gas loss, loss of the inadequacy burning for chemistry mechanics reason, unburned carbon loss, body of heater radiation loss, heat loss due to sensible heat in slag etc.Wherein flue gas loss accounts for more than 90% of total heat loss.Therefore significantly reduce heat loss due to exhaust gas, and this partial heat energy is recycled the key point that becomes boiler energy-saving.10 ~ 15 ℃ of every declines of boiler smoke temperature can improve boiler efficiency 1%, therefore reduce the important channel that the boiler smoke temperature has become boiler energy-saving.
The utility model content
The technical problem that the utility model mainly solves provides a kind of device for recovering waste heat of high-temperature flue, can effectively absorb the heat in the hot industry tail gas, has greatly improved resource utilization, has saved the energy.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of device for recovering waste heat of high-temperature flue is provided, comprises: housing, the high-temperature flue gas import, exhaust gases passes, the tail gas outlet also comprises, blower fan, the air channel of connecting fan, the heat transmission fin group in connection air channel, the hot-blast outlet in connection air channel, be positioned at the thermocouple of exhaust gases passes, the control system that housing is outer.
In preferred embodiment of the utility model, the one layer of heat preservation layer is arranged in the described housing.
In preferred embodiment of the utility model, there is a dust arrester in described high-temperature flue gas import department.
The beneficial effects of the utility model are: the utility model can effectively absorb the heat in the hot industry tail gas, has greatly improved resource utilization, has saved the energy.
Description of drawings
Fig. 1 is the structural representation of a kind of device for recovering waste heat of high-temperature flue one preferred embodiment of the utility model;
The mark of each parts is as follows in the accompanying drawing: 1, high-temperature flue gas import, 2, dust arrester, 3, exhaust gases passes, 4, the tail gas outlet, 5, housing, 6, heat-insulation layer, 7, blower fan, 8, the air channel, 9, hot-blast outlet, 10, the heat transmission fin group, 11, thermocouple, 12, control system.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also the structural representation of a kind of device for recovering waste heat of high-temperature flue one preferred embodiment of Fig. 1 the utility model, the utility model embodiment comprises:
A kind of device for recovering waste heat of high-temperature flue, comprise: housing 5, high-temperature flue gas import 1, exhaust gases passes 3, tail gas outlet 4, also comprise blower fan 7, the air channel 8 of connecting fan, the heat transmission fin group 10 that connects the air channel, the hot-blast outlet 9 that connects the air channel is positioned at the thermocouple 11 of exhaust gases passes, housing control system 12 outward.
Further, one layer of heat preservation layer 6 is arranged in the described housing, prevent heat loss.
Further, there is a dust arrester 2 in described high-temperature flue gas import department, is used for high-temperature flue gas is carried out dedusting, prevents that dust from stopping up exhaust gases passes 3.
Its operation principle is: high-temperature tail gas is come in from high-temperature flue gas import 1, pass through first dust arrester 2 dedustings, the high-temperature tail gas after the dedusting enters exhaust gases passes 3, carries out the heat conversion by heat transmission fin group 10, with the air heat in the air channel 8, reduce simultaneously the temperature of high-temperature tail gas.Described thermocouple 11 is used for detecting the temperature that tail gas exports 4 places, when the temperature in tail gas exit 4 is higher, not fully conversion of heat is described, can by the rotating speed of control system 12 control blower fans 7, improve the circulation of air; When thermocouple 11 detects temperature that tail gas exports 4 places when low, illustrate that the efficient of heat conversion is higher, the air themperature that also can regulate hot-blast outlet place 9 by the rotating speed of controlling blower fan 7.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
