Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] refer to figure 1 , figure 1 It is the front view of the corrugated plate of the present invention. The rectangular stainless steel sheet is pressed into a plate covered with "herringbone"-shaped concave-convex corrugations; the two length edges of the corrugated plate are folded into two 90-degree folds, and the Reserved as a rectangular groove for installing the sealing strip; figure 2 for figure 1 The cross-sectional view at A in the middle shows that the concave-convex corrugations protrude or sink on both sides of the plate with the same size; image 3 for figure 1 The top view of the plate, indicating that the folded edge 3 is folded twice at 90 degrees along the length edge, and the folded edges on both sides are symmetrical;

[0024] refer to Figure 4 , Figure 4 For the fin plate diagram of the present invention, the stainless steel strip thin plate...

Abstract

The invention relates to a fin plate type heat exchanger, in particular to a heat exchanger in a condensation method VOCs organic gas recovering device. At present, a plate type heat exchanger adopted in a condensation method device has the main problems that the pitch of fins is small, pressure drop is large and accumulated water exists. The fin plate type heat exchanger aims to overcome the defects in the prior art and is simple in structure, small in pressure drop, free of accumulated water and easy to manufacture. Rectangular stainless steel sheets are pressed into sheets covered with Y-shaped concave-convex corrugated plates, and V-shaped fins are connected to the surfaces of the sheets. The faces, without the fins, of two sheets are folded, flat steel is embedded in the periphery of the faces, thus the faces are closed, and fin plate type heat exchanger elements are obtained, wherein the middle of each element is provided with concave-convex corrugation gaps, the surface of the outer side of each element is covered with the V-shaped fins, and holes are formed in the opposite angles of each element and connected with pipes to form cold gas logistics inlet and outlet channels; and a plurality of elements are overlapped neatly, and the adjacent spaces of the elements form hot gas logistics channels. An end socket and a connecting pipe are installed on an inlet and an outlet of the two ends of each channel correspondingly, and manufacturing of the fin plate type heat exchanger is completed. Two kinds of gas different in temperature reversely pass through the respective logistics channels to complete sheet dividing wall type heat exchange, and organic gas is condensed and liquefied.

Description

technical field [0001] The invention relates to a finned plate heat exchanger, in particular to a heat exchanger used in a device for recovering VOCs organic gas (including evaporated oil and gas of solvent oil or light oil) by a condensation method. Background technique [0002] The device for recovering VOCs organic gas (including evaporated oil and gas of solvent oil or light oil) by condensation method must cool down the organic gas through a heat exchanger so that it tends to the vapor pressure of the saturated state when it changes from gaseous state to liquid state. Temperature, concentration, to achieve phase change liquefaction, to obtain liquid recovery. [0003] The heat exchanger used in the condensation method recovery device is used to freeze the processed organic gas by the cooling capacity of the refrigerant evaporated gas, and realize the cooling of the organic gas through the "gas-gas" heat exchange. At present, the plate heat exchangers used in the conden...
