Squirrel cage graphite heat exchanger Chemical Properties,Usage,Production

Description

Squirrel cage graphite heat exchanger consists of a ring-shaped impregnated graphite distribution plate and graphite tubes bonded together. The heated (or cooled) medium enters through the inlet pipe and, after being distributed by the distribution plate, is discharged from the outlet pipe after multiple passes. This design is suitable for immersion heating or cooling applications. The allowable temperature range is -20 to 120°C, with a maximum working pressure of 0.2MPa. Both diameter (φA) and height can be customized according to requirements.

Industrial uses

Squirrel cage graphite heat exchanger replaces the traditional lead coil in the process of producing dimethyl fat of oxalic acid and dichloride in the production of methamidophos, so that the heat exchange in the reactor has achieved a change in the way of heat transfer, which has the advantages of high efficiency of heat transfer, strong corrosion resistance, can be designed for a larger area of the heat exchanger to shorten the production cycle, reduce energy consumption, and the life of the product has been greatly extended (normal use of up to four years or more). Service life is 4-5 times that of lead coil, maintenance, easy installation, considerable economic benefits.
The structure of squirrel cage graphite heater is made of upper and lower cover plate, upper and lower tube plate, graphite tube, folding plate and other parts and components cemented together, generally installed in the reaction tank, storage tank, the upper tube plate around the inner wall of the reactor and the reactor with a teflon plate or graphite block card tightly in order to avoid shaking and collision with the container, the tube circulation of corrosive or non-corrosive carriers such as refrigerated brine or satellite water vapour, scaling is slight, the outside of the tube and the contact with corrosive mother liquor, easy to clean. It is easy to clean, the tube can be used Φ32/Φ22, Φ50/Φ36, the internal folding plate is used to improve the heat transfer efficiency, the tube arrangement can be divided into one row, two rows, three rows.
