The invention provides a multifunctional
polyurethane reaction kettle condensation
recovery device which comprises a reaction kettle body, a
gas phase outlet
pipe, an
alcohol-water separator, a connecting
pipe head, a gas guide
pipe, a condenser, a condensate water guide pipe, a flow guide pipe, a
butt joint and a
buffer tank, and the upper outlet of the reaction kettle body is in threaded connection with the
gas phase outlet pipe; and the upper end of the
gas phase outlet pipe is in threaded connection with the
alcohol-water separator. The arrangement of the gas phase valve, the antifouling adsorption box, the adsorption net, the exhaust fan, the dismounting cover, the
exhaust pipe and the
impurity filtering net is beneficial to exhaust treatment of
waste gas, environmental
pollution is avoided, gas in the reaction kettle body is exhausted by opening the gas phase valve, and deep adsorption and
filtration are performed through the adsorption net in the antifouling adsorption box, thegas can be discharged after being filtered by the
impurity filtering net in the
exhaust pipe; the exhaust efficiency can be improved through the exhaust fan, the exhaust effect is guaranteed, cleaningcan be conducted by taking down the dismounting cover and the
exhaust pipe, and maintenance is convenient.
