Summary of the invention
The above-mentioned technical problem existing in order to overcome prior art field, the purpose of this utility model is, a kind of shell and tube exchanger is provided, and is applied in obvious energy conservation in sea-farming, good effect of heat exchange.
The shell and tube exchanger that the utility model provides, it comprises package and some heat exchanger tubes, and package two ends are symmetrically arranged with flange root, tube sheet, bobbin carriage, end plate, transition conduit, gas-liquid delivery pipe, and described package, flange root, tube sheet, bobbin carriage, end plate connect successively.Described end plate is provided with 2 transition conduit, and 1 gas-liquid delivery pipe is all installed in every transition conduit.The two ends of described heat exchanger tube are arranged on respectively on the symmetrically arranged tube sheet in package two ends, and described tube sheet is provided with several installing holes that equate with heat exchanger tube quantity, and heat exchanger tube is fixedly mounted in installing hole.Described bobbin carriage inner side is provided with inlays recess, inlays recess homogenizing plate is installed, and homogenizing plate is provided with several equal discharge orifices, and each equal discharge orifice is relative with the liquid feeding end of each heat exchanger tube respectively, and the cross-sectional area sum of each equal discharge orifice is less than the cross-sectional area sum of heat exchanger tube.Between described homogenizing plate and tube sheet, be provided with pad, on pad, be provided with partition.Water inlet and delivery port are installed on tube wall outside described package, on tube wall, some deflection plates are installed inside described package.
Described package material is PE high density polyethylene pipe, and described heat exchange tube material is internal thread corronil pipe, and described tube sheet material is carbon steel complex copper nickel alloy plate.
The shell and tube exchanger that the utility model provides, its beneficial effect is, is provided with homogenizing plate in bobbin carriage, homogenizing plate is provided with several equal discharge orifices, by equal discharge orifice cold-producing medium, can enter into more uniformly in heat exchanger tube; The cross-sectional area sum of each equal discharge orifice is less than the cross-sectional area sum of heat exchanger tube, therefore the both sides mineralization pressure of homogenizing plate is poor, at cold-producing medium, by after homogenizing plate, can improve the flow velocity of cold-producing medium, heat transfer coefficient in heat exchanger tube can be improved, thereby reach energy-conservation object; Transition conduit is set, and the aperture of transition conduit is greater than the aperture of gas-liquid delivery pipe, can guarantee like this when refrigerant enters bobbin carriage large space by the little space of gas-liquid delivery pipe can not expand immediately, thereby avoid refrigerant when little space enters large space, to have the problem of partial gasification; Some deflection plates are installed on tube wall inside package, under the water conservancy diversion of deflection plate, form folding flow shape turbulent flow continual and steady, dirt is difficult for deposition, and the reduction of sealing factor has improved heat exchange efficiency; Package material is PE high density polyethylene pipe, and its intensity is high, high temperature resistant, anticorrosive, nontoxic, wear-resisting; Heat exchange tube material is internal thread corronil pipe, and its mechanical performance, physical property are all fine, and ductility is good, hardness is high, color and luster is attractive in appearance, be corrosion-resistantly rich in deep drawability and heat exchange efficiency is high.
