Abstract
The utility model, relating to a cross metal slot type heat exchanger, is a waste-heat recoverer of an industrial furnace, and is formed by the welding of a heat-resisting thin metal plate with a square or rectangular groove and a round boss, a reversed U-shaped platform support, an L-shaped sealing strip, a U-shaped expansion-joint, etc. The utility model improves the flowing performance of the air, enhancs the heat-transfer effect, ensures the geometric dimension of a flow channel, decreases the deformation, and also solves the problem of heat expansion. The heat exchanger can both make use of the residual heat in the waste gas exhuasted by an industrial furnace to preheat the air that is needed when the fuel burns.
Description
Cross type metal slot type heat exchanger is the waste-heat recovery device of industrial furnace.It utilizes industrial furnace to discharge waste heat in the flue gas required air or gaseous fuel when giving hot fuel combustion, also can be used for heat blower.
Once used flat board or corrugated plating in the known technology as heat transfer sheet.When flue gas or air are through heat exchanger channel like this, be to pass through with laminar condition, heat-transfer effect is poor, though ridge and groove that United States Patent (USP) Patent Number4605060 metallic plate has corrugated form, but make difficulty, be difficult to adapt to the various industrial furnace flue gas of specification and reclaim employing.At present this class heat exchanger is not all considered the overall thermal expansion issues, can cause bigger distortion or bigger thermal stress during warm above industrial furnace during being applied to, even making residual neat recovering system destroyed.
The purpose of this utility model is exactly the problem that is occurred in the above practical application in order to solve, the heat resisting steel sheet stamping is become to have the groove of square or rectangular, make flue gas and given hot gas and becoming turbulence state when having the narrow narrow slit type passage of emboss pit, increase the heat exchange effect, the plate processing of this band groove is more convenient, is more suitable for various industrial furnaces and selects for use.
Per two heat resisting steel thin plates are formed a heat exchange unit, and as shown in Figure 2, middle slit is wide to be a, is given the hot gas circulation passage.Several roundlet boss are arranged in the middle of the slit, constant to guarantee the path clearance physical dimension.Add several Jiong shape supporting stations between per two groups of heat exchange units, as shown in Figure 3, constant with the gap physical dimension that guarantees exhaust gases passes.Because this supporting station is an independent part in addition, its size and to lay quantity all very flexible, processing easily, take over the configuring u expansion joint at smoke entrance and four squares being given the hot gas inlet and outlet connectors, to reduce the distortion that causes because of expanded by heating and to reduce thermal stress, make the temperature of this heat exchanger applications can be within 400 ℃～900 ℃ scopes.
Its structure of cross type metal slot type heat exchanger as shown in Figure 1.It is that the some groups of heat resisting steel plate sheet welding by two band square or rectangular grooves become 2,4 U-shaped expansion joints 3 of a heat exchange unit 1,4 ┌ shape sealing strip, several Jiong shape supporting stations 4, square take over repeatedly 5 and adpting flange 6 form.
Heat exchange unit 1 as shown in Figure 2, each heat transfer sheet is that thickness is that 1～2 millimeter heat resisting steel thin plate all is stamped into the groove that has square or rectangular, and groove depth is between the 1/2a-a, and several round boss are arranged, and the boss of two heat transfer sheets contacts, and welds.Heat exchange unit middle slit width dimensions is a, by given hot-air from then on slit pass through.Flue gas passes through from the slit f of the combined formation of two heat exchange units, and flue gas is passed to the gas that is given heat through the heat transfer sheet of band groove with heat, because the effect of groove makes flue gas be given hot gas flow with quilt and becomes turbulence state, increases heat-transfer effect.
Some heat exchange units combine becomes a complete heat exchanger main body.Shown in Figure 3 between each heat exchange unit with several Jiong shape supporting stations 4() support, Jiong shape supporting station one side welds with one group of heat exchange unit, the other end is the scope of freedom, this had both guaranteed the distance between the heat exchange unit, just guarantee the exhaust gases passes slit sizes, and also benefited the assembling of heat exchanger.Through welding flue gas and quilt are given hot-gas channel with 4 ┌ shape sealing strips 2 around the complete heat exchanger main body and separated, guaranteed flue gas and given the sealing of hot gas.Flue gas and the import and export of being given hot gas are equipped with U-shaped expansion joint 3, when being out of shape, the heat exchanger expanded by heating can regulate overall dimensions herein, to reduce bulk deformation and to reduce because of being subjected to thermogenetic stress, the square flange 6 of connecting pipe system is connected it by square tube connector 5 with expansion joint, formed a complete cross type metal slot type heat exchanger.It is with the heat resisting steel thin plate through punching press, be welded into a heat exchange unit, according to what of exhaust gas volumn, be combined into the heat exchanger main body with array or tens of groups of heat exchange units, then with itself and ┌ shape sealing strip, the U-shaped expansion joint, square adapter, square flange form through welding assembly.
The utility model compared with prior art, it is good to have a heat-transfer effect, is out of shape for a short time, and has solved advantages such as overall thermal expansion issues.
