Titanium material heat exchange device

Abstract

The invention discloses a titanium material heat exchange device. The device comprises two titanium material side plates which are distributed left and right, and a plurality of relatively independenttitanium material collecting boxes are arranged on the outer sides of the two titanium material side plates correspondingly; all the titanium material collecting boxes are connected in series througha plurality of titanium material heat exchange tubes supported between the two titanium material side plates, so that all the titanium material collecting boxes and all the titanium material heat exchange tubes form a plurality of parallel S-shaped heat exchange pipelines; a steam inlet pipe is arranged at the top of the titanium material collecting box located at the head position of the S-shaped heat exchange pipelines, and a steam outlet pipe is arranged at the bottom of the titanium material collecting box at the tail position of the S-shaped heat exchange pipelines; and a protective sleeve is arranged on the portion, in contact with each titanium material side plate, of each titanium material heat exchange tube in a sleeving mode. The titanium material heat exchange device has the advantages that the structure is compact, the situation that the titanium material heat exchange tubes are damaged due to friction between the titanium material heat exchange tubes and the titanium material side plate in the using process can be avoided, and the service life of the heat exchange tubes is long; and the overall structure is high in stability and strength, the assembling efficiency ishigh, and the use safety is high.

Description

Technical field [0001] The invention relates to the technical field of flue gas heat exchange equipment, in particular to a titanium heat exchange device. Background technique [0002] The exhaust gas produced by the PTA production equipment during the production process will be discharged into the outside through the flue and chimney. Because the exhaust gas produced by the PTA production equipment during the production process is low-temperature saturated flue gas, in order to avoid low-temperature saturated flue gas from being discharged into the outside through the chimney In the process, white flocs are formed and the chimney is damaged. Generally, it is necessary to install a heat exchange device to heat the low-temperature saturated flue gas in the flue. The structure of the heat exchange device currently in use is as follows: It includes two single-layer carbon steel side plates distributed left and right. Between the two carbon steel side plates, several layers of carbon...

AI Technical Summary

Problems solved by technology

The above-mentioned heat exchange device has the following disadvantages: (1) The carbon steel heat exchange tube is installed directly in contact with the carbon steel side plate, and the carbon steel heat exchange tube is easily damaged by friction with the carbon steel side plate during use, resulting in heat exchange The service life of the tube is short; (2) The overall structural stability and strength of the heat exchange device is low; (3) Due to the large number of carbon steel elbows, welding carbon steel elbows is not only time-consuming, labor-intensive, but also prone to weld joints Welding defects affect the safety of the heat exchange device; (4) Poor corrosion resistance, short service life and high cost
