Abstract

The invention discloses a cooling device for chemical materials and a cooling method, and relates to the cooling device and the cooling method. Tube boxes are arranged inside a tube-body shell, multiple heat transferring tubes are arranged between the two tube boxes, and multiple baffle plates are fixed in the middles of the heat transferring tubes; the tube boxes are provided with tube heads, circular sealing plates are provided with center connecting tubes and eccentric connecting tubes, the tube heads are connected with the corresponding center connecting tubes through first rotating sealing pieces, and the circular sealing plates are connected with the corresponding end faces of the tube-body shell through second rotating sealing pieces; two transmission discs are fixed on the two sides of the heat transferring tubes, each transmission disc is provided with ruler teeth and engaged with three gears, shaft rods are fixedly connected with the circular sealing plates, an outer gear ring and two inner gear rings are fixed to the tube-body shell, and each inner gear ring is engaged with the three corresponding gears, the two circular sealing plates are fixed and supported by two standing columns through a bottom plate, a motor is fixed on the bottom plate, and a driving wheel is engaged with the outer gear ring. A planetary gear system is formed by the tube-body shell and a heattransferring assembly, and the efficiency and the effect of convection heat transferring are remarkably improved.

Description

technical field [0001] The invention relates to a cooling device and a cooling method, in particular to a cooling device and a cooling method for chemical raw materials. Background technique [0002] In the chemical industry, heat exchangers are generally used for cooling chemical raw materials in liquid media. Among them, shell-and-tube heat exchangers (also known as shell-and-tube heat exchangers) are currently the most widely used heat exchangers. [0003] In the traditional shell-and-tube heat exchanger, there are two kinds of fluids, cold and hot, which flow in the heat transfer tube, which is called the tube-side fluid, and the other flows outside the heat transfer tube, which is called the shell-side fluid. In order to improve the heat transfer partial coefficient of the shell-side fluid, usually multiple baffles are installed in the shell of the pipe body to increase the velocity of the shell-side fluid, force the fluid to pass through the heat transfer components mu...
