Description
The utility model relates to the spiral heat exchanger in a kind of convection heat transfer' heat-transfer by convection, condensation of gas and liquid evaporation process that is applied to petrochemical industry, papermaking, pharmacy, metallurgical salt manufacturing, system alkali, thermoelectric industry gas-gas, solution-air, liquid-liquid.
Existing heat exchanger mostly is shell and tube greatly, and its material adopts ordinary carbon steel or stainless steel usually, and its volume is big, Heavy Weight, and rate of heat exchange is low, and poor corrosion resistance.In addition, existing heat exchanger medium dirt easily precipitates, and results in blockage, and the cleaning maintenance is inconvenient.
The purpose of this utility model is exactly in order to address the above problem, provide a kind of in light weight, heat exchange area is big, heat transfer efficiency is high, corrosion resistance and good, medium dirt are difficult for precipitation and titanium material four-way spiral heat exchanger easy to maintenance.
Technical solution of the present utility model:
A kind of titanium material four-way spiral heat exchanger, it is made up of the heat exchanging segment one of upper shell and lower house and centre, the upper shell upper end is provided with steam inlet, the lower house lower end is provided with condensate outlet, lower house one side is provided with steam (vapor) outlet, the four-way conveyor screw of heat exchanging segment for forming in the middle of it is characterized in that by four layers of titanium coiled sheet system, this conveyor screw center is provided with the medium central tube, medium central tube upper end causes outside the upper shell by the media outlet pipe, in the spirochetal four-way of middle heat exchanging segment, wherein two septal pathwayses on, following spiral port closed, constitute medium channel, their passage internal orifice is communicated with medium central tube sidewall and connects as one, their passage collar extension is connected with the medium import of middle heat exchanging segment, in the middle heat exchanging segment conveyor screw four-way in addition two septal pathwayses on, following spiral port open, and in the passage, the collar extension sealing, constitute steam channel, its open wide on, following spiral port is communicated with upper shell and steam inlet thereof and lower house and steam (vapor) outlet thereof respectively.
The utility model spiral heat exchanger is to become form concentric spirals channel group component by four titanium coiled sheets, the four-way atlernating edge is a welded seal, two media is contrary heat injection exchange, this heat exchanger diameter is 1800 millimeters, long 3360 millimeters, heat exchange area is 180 square metres, is furnished with two pairs of import and export, is responsible for gas, liquid respectively to be connected.Be the enhanced heat exchange effect, on titanium plate conduit wall, add rectangular block and constitute diversion column, increase the low flow velocity disturbance of medium in passage, the backflow turbulence, not only strengthen heat exchange area, and made medium have the more time before flowing out interchanger, to finish heat transmission, thereby directly improved heat transfer efficiency.Spiral heat exchanger of the present utility model is compared with traditional form, have in light weight, heat exchange area is big, the heat transfer efficiency height, and bearing capacity is strong, corrosion resistance and good, the medium dirt is difficult for precipitation, has overcome advantages such as clogging, because the utility model is detachable structure, then easy to maintenance, its technical indicator marked improvement.The processes such as convection heat transfer' heat-transfer by convection, condensation of gas and liquid evaporation that can be widely used in petrochemical industry, papermaking, pharmacy, metallurgical salt manufacturing, system alkali, thermoelectric industry gas-gas, solution-air, liquid-liquid.
The utility model is described in further detail below in conjunction with accompanying drawing.
