Abstract
The invention discloses a detachable type spiral plate heat exchanger, which comprises a cylindrical shell and a medium I inlet and a medium II outlet which are arranged on the external circumference of the shell, wherein the inside of the shell is provided with double spiral heat exchange plates, a spacing column is welded between two adjacent spiral heat exchange plates, one end of each spiral heat exchange plate is open, the other end of the spiral heat exchange plate is welded with the adjacent spiral heat exchange plate, and the opening ends of the two spiral heat exchange plates are opposite in direction so as to form a medium I flow channel and a medium II flow channel; both ends of the shell are provided with detachable end covers which are in sealing connection with the shell through snibs and sealing washers and are in sealing connection with the opening ends of the spiral heat exchange plates simultaneously; the central positions of the two end covers are provided with a medium I outlet and a medium II inlet respectively; and after the end covers are subjected to prestress treatment, the end covers, which face to one side of the shell, are made into a drum-dish shape with high middle part and low circumferential parts. The detachable type spiral plate heat exchanger has the advantages of bearing higher operating pressure, better heat exchange effect and the like.
Description
Technical field
The present invention relates to a kind of heat exchanger, especially a kind of spiral-plate heat exchanger.
Background technology
Spiral-plate heat exchanger is a kind of heat transmission equipment efficiently, be applicable to the convection heat transfer' heat-transfer by convection of gas-gas, solution-air, liquid-liquid, steam condensation and liquid evaporation heat transfer, can be for the thermal energy exchange of industrial department heating for residential area, UTILIZATION OF VESIDUAL HEAT IN reclaims and long-pending can selecting for use the aspect, have advantages such as cost is low, floor space is little, good effect of heat exchange, but also exist simultaneously the easy fouling of spiral plate to block, shortcoming such as easy to clean not after the fouling.Chinese patent 98210455.8 discloses a kind of flat cover sealing Demountable spiral-plate heat exchanger, there is removable flat cover at the two ends of this spiral-plate heat exchanger, the inner flow passage that can pull down flat cover heat exchanging device cleans, but this flat cover sealing Demountable spiral-plate heat exchanger exists withstand voltage low, only can bear the operating pressure of 1.0MPa, in addition, also exist flat cover bad to the open end sealing effectiveness of spiral plate, the medium gap of the open end by flat cover and spiral plate easily produces Radial Flow, influences shortcomings such as heat exchange effect.
Summary of the invention
The technical problem that invention will solve: the technical problem to be solved in the present invention provides a kind of operating pressure height that bears, the Demountable spiral-plate heat exchanger of heat exchange better effects if.
The technical scheme that the technical solution problem is taked: a kind of Demountable spiral-plate heat exchanger, comprise shell body cylindraceous, be positioned at medium I import and medium II outlet on the shell body excircle, shell body inside is provided with the double helix heat exchanger plates, be welded with spacing column between adjacent spiral heat exchanger plates, one end of every spiral heat exchanger plates opens wide, other end flanging is welded in adjacent spiral heat exchanger plates, the open end direction of two spiral heat exchanger plates is opposite, form medium I runner and medium II runner, two ends at shell body are provided with removable head, removable head is tightly connected by snib and sealing gasket and shell body, open end with the spiral heat exchanger plates is tightly connected simultaneously, and the center of two end cap is respectively equipped with medium I outlet and medium II import, and described end cap is made the dish-shaped shape of drum of projection low around shell body one side is the middle part height through autofrettage.
As preferred version of the present invention, described end cap is 5-15 millimeters to the height of shell body one side projection.
As a further improvement on the present invention, end cap dorsad shell body one side be provided with the interior round table surface of end cap concentric strengthen gusset, the face of cylinder strengthen gusset and outside round table surface reinforcement plate.
Beneficial effect: because it is high low on every side to have adopted autofrettage to make end cap form the middle part in the end cap production process, the dish-shaped shape of drum that is projection, can prevent effectively that the heat exchanger end cap from producing distortion because of internal pressure when heat exchanger is worked, leak, improved spiral-plate heat exchanger operating pressure of the present invention, as further improvement, strengthen gusset by round table surface in the shell side is provided with dorsad at end cap, gusset and outer round table surface reinforcement plate are strengthened in the face of cylinder, the operating pressure of spiral-plate heat exchanger of the present invention is further improved, can reach 4.0MPa, this be common flat cover sealing Demountable spiral-plate heat exchanger institute far can not and, so Demountable spiral-plate heat exchanger of the present invention is applicable to the heat exchange of high pressure medium.
In addition, the dish-shaped end cap of drum that is projection low around the middle part is high is when being tightly connected shell body by snib, the open end and the end cap of spiral plate more closely cooperate, the more flat end cap seal better effects if of effect of sealing, can prevent effectively that medium from radially flowing by spiral plate end and the slit between end cap opened wide, improved heat exchange efficiency.
