Utility model content
The purpose of this utility model is to provide that a kind of heat loss is little, good effect of heat exchange, lamella heat exchanger simple in structure, is especially applicable to being applied to the gas-gas heat exchange between high-temperature flue gas and air in compressed-air energy-storage system.
Lamella heat exchanger, comprise housing and the plate tread assembly that is arranged at enclosure interior, the upper and lower two ends of described housing sidewall is respectively equipped with shell side medium inlet and shell side media outlet pipe, the two ends up and down of described plate tread assembly are respectively equipped with plate journey media outlet pipe and plate journey medium inlet, wherein, described hull outside is provided with heat-insulation layer, and described heat-insulation layer is coated on hull outside.
The hull outside of the utility model lamella heat exchanger is provided with heat-insulation layer, and the heat that can prevent medium in shell side to radiation in air, reduces the thermal loss of medium in shell side by housing, improves the heat exchange efficiency of heat exchanger.
Described housing and heat-insulation layer are respectively cylinder type, and the inwall of described heat-insulation layer and the lateral wall of housing fit.
Housing is cylinder type, can bear the pressure that shell side medium is higher, has improved the bearing capacity of casing-structure heat-exchanger.Heat-insulation layer is hollow cylinder type, and its inwall and housing outer wall fit, and can make heat-insulation layer closely be coated on the outer wall of housing, and high insulating effect, prevents thermal loss and energy waste.
The upper end of heat-insulation layer is positioned at shell side medium inlet below, and the lower end of described heat-insulation layer is positioned at the top of shell side media outlet pipe.
Described hull outside wall is provided with projection, and described heat-insulation layer is provided with the installing hole matching with projection, and described heat-insulation layer hangs on hull outside wall by being connected between installing hole and projection.
Described projection is evenly arranged on hull outside wall.
Described projection is with externally threaded bolt, and described bolt arranges perpendicular to hull outside wall, and one end of described bolt is connected with hull outside wall, and the other end is connected with nut thread through after the installing hole of heat-insulation layer.
The other end of described bolt is provided with pad, and described pad is provided with central through hole, and the other end of described bolt is connected with nut thread after the central through hole through the installing hole of heat-insulation layer, pad successively.
Described heat-insulation layer is asbestos fibre heat-insulation layer or spun-glass insulation layer.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, can prevent lamella heat exchanger heat-energy losses in the course of the work, improve heat utilization rate, prevent energy waste.
