Efficient distillation vacuum cooler

Abstract

The invention discloses an efficient distillation vacuum cooler. The efficient distillation vacuum cooler comprises an upper head, an upper pipe plate, a barrel body, a lower pipe plate, a lower head, a cooling water inlet pipe, pull rods, baffle plates and heat exchange pipes. The upper pipe plate and the lower pipe plate are welded and connected to the upper end and the lower end of the barrel body correspondingly. The baffle plates are arranged in the barrel body through the pull rods. The cooling water inlet pipe is horizontally arranged and fixedly connected to the pipe wall of the lower portion of the barrel body; the baffle plates are composite baffle plates and comprise the flexible baffle plates and the rigid baffle plates; the flexible baffle plates and the rigid baffle plates are connected through non-detachable connection structures; and the outer edges of the flexible baffle plates protrude from the rigid baffle plates and are in interference fit with the inner wall of the barrel body. According to the further improvement, the flexible baffle plates are soft plastic plates or aluminum-plastic plates; the joint, close to the inner wall of the barrel body, of the upper end surface of the lower pipe plate and the barrel body, as well as the joint, close to the inner wall of the barrel body, of the lower end surface of the upper pipe plate and the barrel body are both provided with annular grooves; and a partition plate is arranged in the barrel body, so that an outlet of the cooling water inlet pipe is separated from the heat exchange pipes. The efficient distillation vacuum cooler is high in heat exchange efficiency, small in welding stress, reliable and durable.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a distillation vacuum cooler. Background technique [0002] In the distillation vacuum cooler, there are baffles used to guide the flow direction of the cooling liquid and increase the flow rate. The existing baffle is a rigid plate-shaped member made of metal, plastic or graphite. In order to be inserted into or pulled out of the cylinder during installation or maintenance, a gap must be left between the two, and this gap becomes a cooling device. Leakage forms a short-circuit channel, which will inevitably affect the heat transfer effect, resulting in low heat transfer efficiency of the distillation vacuum cooler. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a high-efficiency distillation vacuum cooler capable of significantly improving heat exchange efficiency. [0004] The present invention achieves technical goals through the...
