SL-type squirrel-cage, insert-type graphite heat exchanger
【Structure and characteristics】
In the production of dimethyl omethoate positions fat, production processes dichloride methamidophos can lead to replace the traditional coil, so that in the reactor coil to achieve a revolution, had the advantage of high efficiency heat transfer, corrosion resistance, and can be designed larger heat exchanger, shortening the production cycle, reduce energy consumption, significantly extended service life, and above normal use up to two years, life expectancy is the lead coil of 4 to 5 times, maintenance, installation convenient, economic benefits were considerable.
Squirrel-cage structure of graphite heat exchanger is a plate from top to bottom, the upper and lower tube plate, graphite tube, baffle cemented by the adoption of such components generally installed in the reactor, tank, the top tube plate and the surrounding reactor wall plate with PTFE or graphite block card tight in order to avoid shaking and impact of container management within the flow of corrosive or pass non-corrosive heat set, such as frozen brine or saturated water vapor, a small scale, tube and mother liquor contact corrosion, easy cleaning, the tube can be selected φ32 / φ22 and two φ50/φ36, internal use of baffles to enhance heat transfer efficiency, with the tube can be divided into a row, two rows, three-row, table for the series of parameters Another form may be other users need to design specifications.
The other is manufactured by impregnating graphite heat exchanger beam (plate heat exchanger) into corrosive materials, the graphite heat exchanger within walking media, external contact with corrosive materials to complete the heat transfer process.
Mainly used for corrosion of materials inside the reactor cooling or heating!
