Problems solved by technology
[0005] However, the above-mentioned semi-floating head heat exchanger has the following disadvantages: (1) When the seal of the tube box at both ends of the heat exchanger leaks, it is necessary to extract the tube sheet and tube bundle from the cylindrical shell as a whole, and then replace all the heads and gaskets (2) The tube sheet of the heat exchanger needs to bear the tension of the bolts, and the material of the tube sheet is generally 10# and other soft materials, which will easily cause the bolts to occlude and be difficult to disassemble (3) When the heat exchanger uses high-pressure medium, it is prone to leakage and the sealing effect is not good

The invention discloses a coil-wound heat exchanger which comprises a housing, tube boxes, a tube plate, a tube bundle, a gland, an elastic sealing plate, a sealing sleeve ring, a sealing filler, a compressing sleeve ring and a connecting tube, wherein two ends of the housing are connected with two tube boxes, a straight tube extends outward from inner sides of end openings of the tube boxes, an inner wall of the straight tube is provided with a first annular sealing table surface, the gland provided with a first via hole is used for tightly pressing the first annular sealing table surface, one end of the sealing sleeve ring is communicated with a second via hole of the elastic sealing plate while the other end of the sealing sleeve ring and the connecting tube form an annulus, the filleris arranged in the annulus, and the sealing filler is compressed via the compressing sleeve ring; the connecting tube extends into the straight tube after ordering running through the compressing sleeve ring, the sealing sleeve ring and the second via hole. The heat exchange is suitable for high pressure and low pressure occasions, great sealing effects can be realized, the tube plate and the tubebundle do not need to be drawn out integrally during disassembling operation, the heat exchanger is convenient to maintain and easy to assemble, and the heat exchanger is great turbulent flow effectsand high in heat exchange coefficient.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to a coiled tube heat exchanger. Background technique [0002] Wound tube heat exchanger refers to a type of spiral tube bundle formed by arranging multi-layer spiral heat exchange tubes between the core cylinder and the outer cylinder (the spiral winding direction of the adjacent two layers of spiral heat exchange tubes is opposite and a certain distance is maintained). . The heat exchange efficiency of this type of coiled tube heat exchanger is 5-7 times that of the traditional shell and tube heat exchanger. It is smaller in size and more convenient to install. It is widely used in medium heat exchange in chemical, food, pharmaceutical and other fields. [0003] Traditional tube-wound heat exchangers generally include a welded shell, tube sheet, and spiral tube bundle. The inlet and outlet of the shell pass are set on the shell, and the inlet and outlet of the tube pass are respectively set on...
