Problems solved by technology
With the enhancement of environmental protection awareness, the improvement of oil quality requires a hydrogenation process under higher temperature and pressure. Hydrogen has the smallest molecule and is a highly permeable flammable and explosive medium. The original sealing structure is difficult to adapt to the new one. Process and management requirements
The above gaskets cannot produce the required pre-deformation and pre-stress, and cannot better adapt to dynamic working conditions

The new sealing structure of the heat exchanger tube box is characterized in that: the new sealing structure of the heat exchanger tube box includes a sealing gland, a fastening nut, a fastening bolt, a diaphragm pad, a left connecting pipe, a right connecting pipe, a pipe box, a pipe Plates, pipe sleeves, and tube bundles; among them: including tube bundles, pipe sleeves and pipe boxes are arranged outside the rows of pipe bundles, tube plates are welded between the pipe boxes and pipe sleeves, left and right connecting pipes are arranged on both sides of the pipe box, and the upper end of the pipe box passes through tight The fixing nut and the fastening bolt are fixed with a sealing gland, and a sealing diaphragm pad is arranged between the sealing gland and the pipe box. The advantages of the present invention: the new sealing structure of the heat exchanger tube box according to the present invention adopts a diaphragm pad with strong elastic deformation capacity, which has a good sealing effect, flexible adjustment of deformation, suitable for dynamic working conditions, simple structure, and convenient installation and disassembly. It solves the problem of difficult installation when the large-diameter diaphragm is heavy, with simple structure, easy assembly, reliable sealing performance, low cost, easy replacement and maintenance, wide application and strong practicability.
Description
Technical field [0001] The invention relates to a sealing technology for a tube box of a tubular heat exchanger in equipment engineering, and in particular provides a new sealing structure for the tube box of a heat exchanger. Background technique [0002] In the prior art, the tube-and-tube heat exchanger is the most widely used type of heat exchanger. The open diaphragm seal structure at the end of the tube box of the tube-and-tube heat exchanger in the prior art, with the deepening of practical application, people It is found that the structure itself also has the following unfavorable problems. First, the structure is special, and the processing accuracy of the spherical arc surface is high; second, a high level of argon arc welding is required, and the end of the tube box and the end cover of the tube box cannot be damaged. High technical requirements; third, high installation accuracy; fourth, inconvenient disassembly, sealing welds need to be removed, side rings are vulner...
