Abstract
The utility model relates to a heat exchanger used for the recovery of waste heat in metallurgical and petrochemical industries, namely, an enthalpy-entropy (tempolabile gas waste heat recoverer). The waste heat recoverer comprises a heat transfer plate bundle, a plate box, a shell side nozzle, a flange, a housing, a connecting plate and a support saddle, wherein, the heat transfer plate bundle is arranged in the housing; the plate box is arranged at the two ends of the housing; the connecting plate is arranged between the plate box and the housing; the shell side nozzle and the flange are arranged on the housing and the support saddle is arranged beneath the housing. The utility model has reasonable structure, simple manufacture and high heat transfer coefficient.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig, a kind ofly specifically is used for metallurgical and the petroleum chemical industry waste heat recovery is used that heat exchanger---the enthalpy entropy is a variant gas waste-heat recover.
Background technology
That the heat exchanger of our present usefulness has is board-like, tubular type, spiral plate type etc., but it is few to be specifically designed to the spy of waste heat recovery; The pipe heat exchanger heaviness, it is more to consume metal material, and the restriction of plate type heat exchanger gasket seal non-refractory can not be used for waste heat recovery, and spiral heat exchanger is used for waste heat recovery and limited by width of flow path and easy laying dust.Be used for waste heat recovery though fin-tube heat exchanger has, owing to the easy dust stratification dirt of finned tube has a strong impact on heat transfer efficiency.Waste heat boiler only is applicable to high-temperature flue gas, and it is too many to use this heat exchanger to consume metal material for the various waste hot airs of low pressure, and is economical inadequately.Solve this problem so in this case, press for a kind of heat exchanger.Thereby the needs of facing the reality, having developed the enthalpy entropy is variant gas waste-heat recover, it has filled up domestic blank.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of promptly high temperature resistant, not only be difficult for that dust stratification and fouling, heat transfer efficiency but also high heat exchanger---the enthalpy entropy is a variant gas waste-heat recover.
The purpose of this utility model is to realize like this, this waste-heat recoverer comprises heat transfer plate bundle 1, plate case 2, shell side adapter and flange 3, housing 4, gusset piece 5, bearing 6, described heat transfer plate bundle 1 is arranged on the inside of housing 4, plate case 2 is arranged on the two ends of housing 4, gusset piece 5 is arranged between plate case 2 and the housing 4, shell side is taken over and flange 3 is arranged on the housing 4, bearing 6 be arranged on housing 4 below.
Described heat transfer plate bundle 1 by two heat transferring plates 7 by all side seam postweldings seal, mid portion carries out the resistance spot welding of multi-section position, form a plurality of cavitys 8 by pressurization in heat transferring plate and constitute.
The utility model is rational in infrastructure, makes simply the heat transfer coefficient height.Owing to when the plate beam shaping, form several resistance spot weld nuclear, some nuclear makes continuous change of the flow direction of medium make medium can reach turbulent flow under low speed, thereby reaches the purpose of augmentation of heat transfer.The batch (-type) turbulent flow is not stopped up, resistance is little, can prevent the long-pending crevice corrosion that becomes silted up and cause of medium.

Fig. 2 is the utility model heat transfer plate bundle structural representation.
The specific embodiment
Shown in accompanying drawing: this waste-heat recoverer comprises heat transfer plate bundle 1, plate case 2, shell side adapter and flange 3, housing 4, gusset piece 5, bearing 6, described heat transfer plate bundle 1 is arranged on the inside of housing 4, plate case 2 is arranged on the two ends of housing 4, gusset piece 5 is arranged between plate case 2 and the housing 4, shell side is taken over and flange 3 is arranged on the housing 4, bearing 6 be arranged on housing 4 below.
Described heat transfer plate bundle 1 by two heat transferring plates 7 by all side seam postweldings seal, mid portion carries out the resistance spot welding of multi-section position, form a plurality of cavitys 8 by pressurization in heat transferring plate and constitute.
Heat transfer plate bundle 1 is the minimum unit that conducts heat, process is that two heat transferring plates 7 are sealed by all side seam postweldings, resistance spot welding is carried out by certain rule in the centre, on heat transfer plate bundle 1, stay an osculum, adapter of weldering on it, pressurization makes that promptly the periphery seam is welded together in pipe, heave a cavity that convex-concave is alternate between middle two heat transferring plates 7 that carry out resistance spot welding by certain rule, two ends are carried out the shaping processing and are promptly formed heat transfer plate bundle 1, heat transfer plate bundle 1 is welded in formation plate journey (heat transfer plate bundle inner passage) and two runners of shell side (passage between the heat transfer plate bundle) on gusset piece 5 and the housing 4 by certain rule, thereby conducts heat.
This heat exchanger heat transfer theory as shown in Figure 2, waste hot air medium I such as flue gas walk shell side, are difficult for dust stratification, heat-absorbing medium II limp journey.Owing to when the plate beam shaping, form several resistance spot weld nuclear, some nuclear makes continuous change of the flow direction of medium make medium can reach turbulent flow under low speed, thereby reaches the purpose of augmentation of heat transfer.
