Further, described outside semi circular shells is the large shell in the outside, and inboard semi circular shells is little shell, and inboard semi circular shells separates cold and hot medium.
Further, described core body lower end is supported by lower support, lower support is made of eight supportings, and the bottom is fixed on the housing, and the top is provided with the top, every supporting is cylindricality, be bolt structure, can control the length that it stretches out by rotary jacking head, be bearing in respectively near four angles, core body lower end, be the extruding support pattern, but core body lower end easy on and off moves.
Further, the bottom of described heat exchanger is provided with feed tube, and feed tube communicates with cold medium tube, on the feed tube at pipe connecting flange to two expansion joints are housed respectively between the distance of core body.
The heat exchange principle of the lamella heat exchanger that the utility model relates to is: composing plate pair after two rectangle corrugated cardboard sheets stack welding forms core body by the plate of some after to the stack welding again.The medium of core body top and bottom is imported and exported quantity and be can be 3, and cold medium A flows through from the both sides mouth of core body, and thermal medium B flows through from the middle port of core body, and two media is pure adverse current; The medium of core body top and bottom is imported and exported quantity and also be can be 2 openings, and cold medium A flows through from a side mouth of core body, and thermal medium B flows through from another side mouth of core body, and two media is pure adverse current.
Cold medium A enters in the housing, is full of housing, and liquid material enters housing from feed tube, mixes with cold medium A; Blending agent enters core body inside by the core body bottom open end, forms shell side, such as core body lower ending opening structure designed in the technical program and feed tube structure; Thermal medium B enters core body in taking over, carry out countercurrent flow with cold medium A, forms the plate journey, the structure that directly communicates such as adapter designed in the technical program and core body, make in core body that wherein a kind of medium is in a side, another kind of medium moves at opposite side, forms heat exchange.By the shell side medium core body is freely compressed, core body only bears the poor of media of both sides, and housing bears high-pressure medium pressure.
