[0001] The utility model relates to the technical field of steam condensers, in particular to a steam condenser with high efficiency and heat exchange for the production of 5-chlorovaleronitrile. Background Art

[0002] 5-Chlorovaleronitrile is a colorless or pale yellow liquid that can be used to synthesize some pesticides and plays an important role in the pesticide field. During its production, a mixed gas containing steam is generated. The condenser can use the cooling medium to exchange heat with the hot steam, causing the steam to liquefy when cooled, thereby achieving the transition from gas to liquid and achieving the purpose of separating the steam from the mixed gas.

The water pump 202 drives the solution through the connecting pipe 203 and the medicine outlet pipe 204 into the medicine dispersing pipe 206, so that the solution can enter the medicine dispersing pipe 206 and be sprayed on the circumferential wall of the condenser body 1 through a number of medicine dispersing buckets. The solution sprayed on the inner wall flows down and reacts with the scale on the side wall. After spraying is completed, the cylinder 1 is started. 03, lift the cover plate 2 up and move it aside, then drive another set of sliders 101 to drive the collecting tray 301 and the scraper 302 to the top of the condenser body 1, and then thread the bolt 402 into the threaded hole of the slider 101 and the fixing frame 401 again. At this time, the center position of the collecting tray 301 and the center position of the condenser body 1 are also in the same vertical position, and then start the cylinder 103, and the cylinder 103 drives the lifting rod 5 to move down, and the lifting rod 5 drives the collecting tray 301 and the scraper 302 to move down. When moving down, the scraper 302 fits the inner wall, so that part of the scale can be scraped off and dropped on the bottom of the condenser body 1, and then moves up and down reciprocatingly. When moving up, the scale on the inner wall can be scraped off and then dropped into the collecting tray 301, and the scale that falls on the bottom end of the condenser body 1 can be poured out later, thereby cleaning the scale on the inner wall.

[0035] It should be added that the cover plate 2 can fit into the top of the condenser body 1, and can be placed on the top of the condenser body 1 for sealing when in use, and the air inlet pipe 6 and the liquid outlet pipe 7 are respectively installed on both sides of the condenser body 1, and the bottom end of the connecting rod 3 is at the same horizontal position as the bottom end of the condenser body 1, so that when it is placed on the ground, the connecting rod 3 can play a supporting role, and the added solution is an acidic solution, which can react with the scale to make it easier to fall off.
