Description
Technical field
The utility model relates to a kind of heat-exchanger rig, is the improvement of shell-and-tube heat exchanger on structure and performance.
Background technology
At present, shell-and-tube heat exchanger commonly used is made up of cylindrical shell, the tube bank that is parallel to housing, longitudinal baffle, pass partition, deflection plate, backstay etc., and the shortcoming of this heat exchanger is: volume is big, heavy, shortcomings such as the coefficient of heat transfer is low, easy fouling.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of double cut helix tube contra-flow heat exchanger, and existing shell-and-tube heat exchanger volume is big, heavy to solve, shortcomings such as the coefficient of heat transfer is low, easy fouling.
The technical solution adopted in the utility model is: a kind of double cut helix tube contra-flow heat exchanger, comprise housing, housing the cold fluid intake chamber and the water-supplying chamber of the formation of two ends end socket up and down, the cold fluid intake chamber is connected cold fluid inlet tube and outlet respectively with water-supplying chamber, mutual reverse acting spiral is coiling the screw thread heat exchanger tube in the housing, every layer of screw thread heat exchanger tube is around to identical, but adjacent layer screw thread heat exchanger tube winding direction is opposite.The two ends of screw thread heat exchanger tube are fixed on the lower perforated plate, welding of screw thread heat exchanger tube or expanded joint are on upper perforated plate and lower perforated plate, last lower perforated plate is welded on the housing on the low head, and be positioned at the same side of housing, or opposite both sides, tube sheet is fixed on the housing, the import and export pipe of hot fluid is connected with housing tube sheet up and down, and be distributed in the two ends up and down of housing, hot fluid inlet tube and cold fluid outlet are positioned at the upper end of housing, and the axis angle of two outlets is the 90-120 degree.Hot fluid outlet and cold fluid inlet tube are positioned at the lower end of housing, and two outlet tubular axis wire clamp angles are identical with axis angle between hot fluid inlet tube and cold fluid outlet.
The screw thread heat-exchanging tube bundle coils outside the core pipe, divide multilayer disc around, adjacent layer around on the contrary.The core pipe is positioned at the housing center, is fixed by two ends core pipe holder.Leave the gap between internal layer screw thread heat exchanger tube and the core pipe, last one deck and inner walls also leave the gap, leave the spacing that slight vibration is not is not worn and torn mutually between the screw thread heat exchanger tube, and the screw thread heat exchanger tube adopts stainless steel seamless pipe or copper tube to form through rolling.Pipe thickness 0.4-1.2mm.The screw thread heat exchanger tube coiling number of turns and the number of plies are calculated through heating power by heat exchange load and heat exchange area and are determined that shell material adopts stainless steel or carbon steel.
Adopt good effect of the present utility model to be: to reduce heat exchanger volume, increased the coefficient of heat transfer, made the coefficient of heat transfer reach 9200W/m
2. more than ℃.Because of the omnidistance high velocity turbulent flow of cold fluid in addition the vibration of screw thread heat exchanger tube self make tube wall be difficult to fouling.
