3 results about "(Hydroxyethyl)methacrylate" patented technology

The invention provides a hydroxyethyl methylacrylate processing reaction kettle, which comprises a base, the top end of the base is respectively provided with a protective cylinder and a recovery box, the front end of the recovery box is inserted with an air suction cylinder, the front end of the air suction cylinder extends to the inner side of the protective cylinder, the inner side of the air suction cylinder is fixedly connected with an air extractor, and the air extractor is fixedly connected with an air outlet of the recovery box. Through cooperation of a lower U-shaped guide pipe and a one-way valve, hydroxyethyl methacrylate steam is guided to the bottom of the inner side of a sealing mechanism composed of a base, a protective cylinder and a sealing cover, and the hydroxyethyl methacrylate steam is guided into a cooling cavity of a recycling box through an air suction cylinder and an air suction fan; hydroxyethyl methylacrylate steam is guided into the buffer cavity through the guide pipe, and is guided into the water-soluble cavity through the communicating pipe, so that cooling and water-soluble absorption of hydroxyethyl methylacrylate are completed; the problems that existing equipment is insufficient in hydroxyethyl methylacrylate steam recovery, air pressure adjustment and cleaning treatment are solved.
