A straight-through spiral plate heat exchange device

Abstract

The invention discloses a straight-through type spiral plate heat exchange device which comprises a tank body, a feeding pipe, a discharging pipe, an annular spraying pipe, an outer spiral plate, round steel, an inner spiral plate, a middle partition plate, a sealing plate, a liquid inlet pipe, a supporting ring and a liquid outlet pipe. During work, cooling liquid enters a sealed cavity formed by the outer spiral plate, the round steel and the inner spiral plate through the liquid inlet pipe and is finally discharged out through the liquid outlet pipe; to-be-cooled high-temperature materials enter the tank body through the feeding pipe, due to the fact that the space of the tank body becomes larger suddenly, the materials slowly enter a cavity between the outer spiral plate and the inner spiral plate and then make sufficient contact with the outer spiral plate and the inner spiral plate so as to conduct heat exchange, and therefore cooling is conducted; and the cooled materials are discharged out through the discharging pipe, cooling liquid is pumped into the annular spraying pipe, the cooling liquid is sprayed out from a spraying hole, and therefore auxiliary cooling is conducted on the materials. The straight-through type spiral plate heat exchange device is simple in structure, large in heat exchange rear and high in heat exchange efficiency, the materials cannot be blocked and gathered, and the service life is long.

Description

technical field [0001] The invention relates to a spiral heat exchange device, in particular to a straight-through spiral plate heat exchange device. Background technique [0002] Heat exchangers are widely used in industrial production, such as petrochemical, light industry, medicine, food, medicine, aerospace and other industrial sectors. Most of the existing heat exchangers are shell and tube Heat exchangers and spiral plate heat exchangers, shell and tube heat exchangers have the disadvantage of low heat exchange efficiency, and the disadvantages of spiral plate heat exchangers are that residual raw materials remain inside the device and are not easy to discharge and cause blockage. In view of the above defects, it is necessary to design a straight-through spiral plate heat exchange device.
