AI Technical Summary
Existing melamine production cooling equipment has low cooling efficiency, the cooling medium temperature rises rapidly, it needs to be replaced frequently, the operation is cumbersome, and the contact area between the cooling pipe and the high-temperature reaction gas is small.
A cooling device was designed in which the cooling pipe is immersed in the coolant for all-round heat exchange. The connection stability is improved by threaded connection, and an exhaust fan is set to control the gas flow rate. Multiple sets of coolant are used for heat exchange to reduce frequent replacement.
It improves heat exchange efficiency, reduces the rate of temperature rise of the coolant, reduces the need for frequent coolant changes, and improves ease of use.
