Heat exchange tube box structure for energy-saving type air pretreatment device

Abstract

The invention provides a heat exchange tube box structure for an energy-saving type air pretreatment device. The heat exchange tube box structure for the energy-saving type air pretreatment device cansolve the problem that due to the fact that heat exchange tubes of a first group of pipe box of an existing air pretreatment device are fixedly welded on tube plates, the leakage risk of the heat exchange tubes exists. The heat exchange tube box structure comprises fin heat exchange tubes and tube plates, wherein the two ends of the fin heat exchange tubes penetrate through the tube plates correspondingly; the heat exchange tube box structure further comprises U-shaped elbows; the fin heat exchange tubes are arranged in an up-and-down multi-layer mode, and each fin heat exchange tube is horizontally arranged; every two adjacent fin heat exchange tubes of the fin heat exchange tubes located on the same layer communicate with each other through the U-shaped elbows in an end-to-end mode; the inlet ends of the fin heat exchange tubes of each layer communicate with a water inlet pipe; the outlet ends of the fin heat exchange tubes of each layer communicate with a water outlet pipe; one end of the water inlet pipe is closed, and the other end of the water inlet pipe is connected with a water inlet; and one end of the water outlet pipe is closed, and the other end of the water outlet pipe is connected with a water outlet.

Description

technical field [0001] The invention relates to the field of air pretreatment devices in the fermentation and pharmaceutical industries, in particular to a heat exchange pipe box structure for an energy-saving air pretreatment device. Background technique [0002] The invention patent with the patent number ZL200910208228.9 discloses an energy-saving air pretreatment method and device, which can recover the waste heat in the compressed air, replace steam to heat the air, or replace steam as the power of the lithium bromide refrigerator. The energy saving effect is very remarkable. [0003] In this device, finned heat exchange tubes are used in the tube box of the air cooling and water removal device. The heat exchange tubes are arranged vertically and side by side. The two ends of the heat exchange tubes respectively pass through the tube plate and are welded to the tube plate. . The first group of tube boxes of the air-cooled water removal device first conducts heat excha...
