Abstract
An improved semi-welded plate heat exchanger comprises a fixed keep plate, a movable keep plate and more than two sheet bar pairs. Each sheet bar pair is provided with two sheet bars; a plurality of convex or concave touch points are distributed in each sheet bar in a netty mode; the two sheet bars are mutually supported and form a first medium flowing channel; the edges of the two sheet bars are welded along seal grooves; any two adjacent sheet bar pairs are mutually supported through the touch points and form a second medium flowing channel; a peripheral sealing cushion is arranged between the peripheries of any two adjacent sheet bar pairs; the periphery of the corresponding second medium flowing channel in any two adjacent sheet bar pairs is provided with a seal ring. First media pass through the first medium flowing channels, second media pass through the second medium flowing channels, and heat exchange is achieved. According to the improved semi-welded plate heat exchanger, the usage amount of conventional sealant and the usage amount of special sealant are saved, cost is lowered, and risks of adverse reactions are reduced.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to heat exchanger, particularly a kind of improved heat-exchangers of the plate type that partly welds.
Background technology:
Partly weld heat-exchangers of the plate type by plate to forming, each plate is to consisting of with Laser Welding welding along seal groove two plates.A plurality of plates to sealing gasket sealing, are installed in the middle of fixed pressure plate and movable pressure plate with the form superposeing, form heat exchanger.Partly weld heat-exchangers of the plate type and there is the features such as heat transfer efficiency is high, long service life, easy access, be applicable to cooling and chemical treatment, it is the rational selection that substitutes shell-and-tube and welded plate heat exchanger, particularly be applicable to evaporation and the condensation of Ammonia cooling agent, and the chemical treatment technology of corrosive liquids.Be mainly used in the industrial circles such as ammonia refrigeration, sulfuric acid, caustic soda, petrochemical industry, metallurgy, machinery, pharmacy, food.But in actual use, partly weld heat-exchangers of the plate type when the chemical treatment technology of the evaporation for Ammonia cooling agent and condensation and corrosive liquids, special gelatin consumption is large, and cost is high, has the risk of bad reaction.
Summary of the invention:
The object of the present invention is to provide a kind of improved heat-exchangers of the plate type that partly welds, the described this improved heat-exchangers of the plate type that partly welds will solve in prior art partly welding that heat-exchangers of the plate type special gelatin consumption is large, cost is high, have the technical problem of bad reaction risk for corrosive liquids.
This improved heat-exchangers of the plate type that partly welds of the present invention, comprise fixed pressure plate, the plate pair of movable pressure plate and two above numbers, described fixed pressure plate is connected by connector with movable pressure plate, described plate is installed between fixed pressure plate and movable pressure plate after superposeing, any one plate is to all including separately two plates, in plate described in any one, all with web form, be distributed with a plurality of raised or sunken contacts, in any one plate, be provided with a first medium sprue through hole and a second medium sprue through hole, any one plate centering, between two plates, by described contact, support mutually and form first medium runner, first medium sprue through hole on two plates is communicated with the two ends of described first medium runner respectively, wherein, any one plate centering, between the edge of two plates, be provided with the seal groove cooperatively interacting, two plates are along described seal groove welding, any two adjacent plates between all by contact, support mutually and form second medium runner, the second medium sprue through hole of any two adjacent plate centerings is communicated with the two ends of described second medium runner respectively, between the right periphery of any two adjacent plates, be provided with peripheral sealing pad, the second medium sprue bore periphery of any two adjacent plate centerings is all provided with sealing ring separately.
Further, any one plate centering, the contact that is in contact with one another support between two plates is welded to connect.
Further, described peripheral sealing pad and sealing ring consists of colloid.
Operation principle of the present invention is: in the first medium runner of plate centering by first medium, plate between second medium runner in by second medium, realize the heat exchange between first medium and second medium.When second medium is conventional media, peripheral sealing pad and sealing ring adopt conventional glue to form, and for example, when second medium is Special Medium (the more serious material of corrosivity), peripheral sealing pad and sealing ring adopt special gelatin (for example corrosion resistance glue) to form.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention in the first medium runner of plate centering that partly welds heat-exchangers of the plate type by first medium, plate between second medium runner in by second medium, realize the heat exchange between first medium and second medium.When second medium is conventional media, peripheral sealing pad and sealing ring adopt conventional glue to form, when second medium is Special Medium, peripheral sealing pad and sealing ring adopt special gelatin to form, the consumption of having saved conventional glue and special gelatin, has reduced cost, has reduced the risk of bad reaction.

The specific embodiment:
Embodiment 1:
As Fig. 1, shown in Fig. 2 and Fig. 3, a modification of the present invention partly weld heat-exchangers of the plate type, comprise fixed pressure plate (not shown), the plate of movable pressure plate (not shown) and two above numbers is to 1, described fixed pressure plate is connected by connector with movable pressure plate, described plate is installed between fixed pressure plate and movable pressure plate after to 1 stack, any one plate all includes two plates 2 separately to 1, in plate 2 described in any one, all with web form, be distributed with a plurality of raised or sunken contacts, in any one plate 2, be provided with a first medium sprue through hole 3 and a second medium sprue through hole 4, in 2 pairs 1 of any one plates, between two plates 2, by contact 7, support mutually and form first medium runner, first medium sprue through hole 3 on two plates 2 is communicated with the two ends of described first medium runner respectively, wherein, in 2 pairs 1 of any one plates, between the edge of two plates 2, be provided with the seal groove cooperatively interacting, two plates 2 are along described seal groove welding, between 2 pairs 1 of any two adjacent plates, all by contact, support mutually and form second medium runner, second medium sprue through hole 4 in 2 pairs 1 of any two adjacent plates is communicated with the two ends of described second medium runner respectively, between the periphery that any two adjacent plates are 2 pairs 1, be provided with peripheral sealing pad 5, second medium sprue through hole 4 peripheries in 2 pairs 1 of any two adjacent plates are all provided with sealing ring 6 separately.
Further, in 2 pairs 1 of any one plates, the contact that is in contact with one another support between two plates 2 is welded to connect.
Further, described peripheral sealing pad 5 and sealing ring 6 consist of colloid.
