Abstract

The invention relates to a titanium tube heat exchanger for recovering low-temperature flue gas waste heat and eliminating white smoke in a flue gas system in the power industry, in particular to a titanium tube heat exchanger for recovering low-temperature flue gas waste heat, and aims at solving the problem of how to utilize the low-temperature waste heat in the flue gas system to supplement low-temperature desalted water needing to enter a condenser and heat low-temperature condensed water to recycle low-quality heat. Each heat exchanger structure comprises a front water chamber, a rear water chamber, a condenser front end tube plate, a condenser rear end tube plate and multiple heat exchange tubes, wherein one side of the condenser front end tube plate is connected with one side of thecondenser rear end tube plate through the multiple heat exchange tubes, a cooling water inlet and a cooling water inlet are formed in the front water chamber, the front water chamber is arranged on the other side of the condenser front end tube plate, and the rear water chamber is arranged on the other side of the condenser rear end tube plate. The titanium tube heat exchanger is additionally arranged for achieving deep waste heat recycling, low-quality flue gas waste heat can be deeply recycled to heat low-temperature desalted water and condensed water, and the effect of flue gas condensation and white smoke elimination can be achieved.

Description

technical field [0001] The invention relates to a titanium tube heat exchanger for recovering and eliminating waste heat of low-temperature flue gas in a flue gas system in the electric power industry, in particular to a titanium tube heat exchanger for recovering low-temperature flue gas waste heat. Background technique [0002] In recent years, power plants have paid special attention to the utilization of waste heat in the process of promoting energy saving, consumption reduction and environmental protection. After the low-pressure cylinder is removed and modified, only a very small amount of cooling steam enters the low-pressure cylinder during normal operation. And low-temperature condensate water, but it is wasteful to consume precious steam resources to heat low-temperature water. On the other hand, there are a lot of low-temperature waste heat resources in the desulfurization flue gas system. The use of flue gas condensation technology to achieve deep waste heat reco...
