Abstract
A heat-treatment combustion air heating device comprises a natural exhaust port connected with a primary heat exchange box and a secondary heat exchange box respectively through air pipes, wherein the primary heat exchange box is connected with a combustion air blower and the secondary heat exchange box through air pipes; both the primary heat exchange box and the secondary heat exchange box are equipped with residual hot air discharge pipes; the secondary heat exchange box is connected with a combustor through an air pipe; and the combustor is further equipped with a cold air ignition electrode air pipe and an ignition detector cooling air pipe which are both connected with an ignition air blower. When the heat treatment combustion air heating device is in operation, combustion air and high-temperature tail gas in the natural exhaust port serve as combustion air of the combustor after heat exchange, and ignition combustion air is supplied by the ignition air blower. The heat treatment combustion air heating device has the characteristics of simple structure and high waste heat utilization ratio, and saves fuel consumption.
Description
Technical field
The utility model relates to a kind of residual heat using device, and the spy relates to a kind of heat treatment combustion air heater fully.
Background technology
At machine industry, to the general directly mode of discharging that adopts of high-temperature gas that heat-treatment furnace produced, wasted the entrained heat of high-temperature gas greatly, in some residual heat using device, utilize high-temperature gas heating service water, but receive season limit, can not make full use of waste heat summer, makes utilization rate of waste heat receive restriction; And the needed a large amount of combustion airs of heat-treatment furnace still adopt cold air combustion-supporting at present, cause fuel consumption big.
Summary of the invention
The utility model proposes a kind of heat treatment combustion air heater at the deficiency that prior art exists, and this device has simple in structure, and the characteristics that utilization rate of waste heat is high have been saved fuel consumption.
The technical solution of the utility model is achieved in that a kind of heat treatment combustion air heater, it is characterized in that: comprise the nature exhaust outlet, the nature exhaust outlet is connected with the secondary heat exchange case with the one-level heat exchange case respectively by airduct, the one-level heat exchange case is connected with the combustion air air blast by airduct, the one-level heat exchange case is connected with the secondary heat exchange case by airduct, all be equipped with the waste hot air delivery pipe on one-level heat exchange case and the secondary heat exchange case, the secondary heat exchange case links to each other with combustor by airduct, also be equipped with cold air ignitor airduct and ignition detector cooling duct on the combustor, cold air ignitor airduct is connected with the igniting air-blaster with the ignition detector cooling duct.
Described one-level heat exchange case and secondary heat exchange case is characterized in that: one-level heat exchange case and secondary heat exchange case include heat-exchange tube, are equipped with the helical form flow guide bar in the heat-exchange tube, and heat-exchange tube is assemblied in the heat exchange case by perforated plate.
Because the utility model has adopted independently ignitor wind path, carries cold air separately, ignitor blast when having prevented igniting; Since the heat exchange of combustion air process secondary, and be provided with deflector in the heat-exchange tube, and so UTILIZATION OF VESIDUAL HEAT IN efficient height, the secondary waste heat supply temperature can reach between 180 ℃-260 ℃.

Fig. 2: the schematic diagram of the utility model heat exchange case;
Fig. 3: the A-A of the utility model heat exchange case is to generalized section
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are elaborated.
With reference to Fig. 1,2,3, a kind of heat treatment combustion air heater, it is characterized in that: comprise nature exhaust outlet 1, nature exhaust outlet 1 is connected with secondary heat exchange case 17 with one-level heat exchange case 7 respectively by airduct 9, one-level heat exchange case 7 is connected with combustion air air blast 6 by airduct 8, one-level heat exchange case 7 is connected with secondary heat exchange case 17 by airduct 10, all be equipped with waste hot air delivery pipe 4 on one-level heat exchange case 7 and the secondary heat exchange case 17, secondary heat exchange case 17 links to each other with combustor 2 by airduct 11, also be equipped with cold air ignitor airduct 12 and ignition detector cooling duct 13 on the combustor 2, cold air ignitor airduct 12 is connected with igniting air-blaster 5 with ignition detector cooling duct 13.
Described one-level heat exchange case 7 and secondary heat exchange case 17, it is characterized in that: one-level heat exchange case 7 and secondary heat exchange case 17 include heat-exchange tube 18, be equipped with helical form flow guide bar 19 in the heat-exchange tube 18, heat-exchange tube 18 is assemblied in the heat exchange case by perforated plate 22.
During work, 3 runnings of updraft type circulating fan, make heat that burning produced respectively in the thermal treatment zone 14, circulation in heat preservation zone 15 and discharge zone 16 form, hot gas in the discharge zone 16 flow to heat preservation zone 15 by the below, unnecessary hot gas is from 1 discharge of natural exhaust mouth and in airduct 9 enters one-level heat exchange case 7, enter flow of cold air district 21 through the mobile district 20 of heat-exchange tube 18 and helical form flow guide bar 19 formed hot-airs with process airduct 8 and carry out heat exchange, hot-air flows district's 20 interior air heat exchange after 4 dischargings of excess enthalpy hot air discharge pipe, air in the flow of cold air district 21 carries out entering secondary heat exchange case 17 through airduct 10 after the heat exchange, airduct 10 enters the hot gas that enters in the air of secondary heat exchange case 17 and the airduct 9 and carry out heat exchange in secondary heat exchange case 17, the air that airduct 10 enters secondary heat exchange case 17 passes through airduct 11 combustion-supporting combustors 2 after heat exchange, air in cold air ignitor airduct 12 and the ignition detector cooling duct 13 is carried cold air separately by igniting air-blaster 5, ignitor blast when preventing to light a fire.
