Multifunctional polyurethane reaction kettle condensation recovery device

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of polyurethane production equipment, and in particular relates to a multifunctional polyurethane reactor condensation recovery device. Background technique [0002] Polyurethane is an important polymer material, which is made by the reaction of polyisocyanate, oligomer polyol and organic small molecule polyol. Polyurethane has the advantages of wear resistance, oil resistance, weather resistance, aging resistance, high tear strength and good low temperature flexibility. It is usually used in foam plastics, elastomers, coatings, adhesives, fibers, synthetic leather, waterproof materials and paving materials A variety of product forms are used in many fields. [0003] At present, in the process of preparing polyurethane, the generated water and unreacted alcohol are discharged from the gas phase outlet, and flow back into the polyurethane reactor through the condensing device. [0004] However, the existing...
