Problems solved by technology
Due to the large difference between the pressure of the steam condensate and feed water and the pressure of the heat exchanger itself, if the buffer space of the condensate inlet of the waste heat boiler of the incinerator is insufficient at this time, or the steam trap valve fails, or the load of the device fluctuates violently, the Condensed water and external feed water will cause serious erosion of heat exchanger tubes, resulting in equipment damage
The existing technical problem of damage to the heat exchange tubes of a high-temperature steam tube heat exchanger due to long-term erosion seriously threatens normal production and operation and equipment safety, and increases maintenance costs

A high-temperature steam tubular heat exchanger comprises a shell body, a heat exchange pipeline, a water supply pipe, a drainage pipe and a buffer assembly. A water inlet and a water outlet are formed in the shell body. The heat exchange pipeline is arranged in the shell body, and the buffer assembly is arranged in the shell body and further located at the water inlet. The buffer assembly is provided with a buffer inlet, a buffer outlet and a heat exchange cavity which communicates with the buffer inlet and the buffer outlet. The forming direction of the buffer outlet is parallel to the axisof the heat exchange pipeline. The water supply pipe communicates with a steam inlet. The drainage pipe communicates with a steam outlet, and the water supply pipe and the drainage pipe are both usedfor conveying heat exchange media.
Description
technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a high-temperature steam tube heat exchanger. Background technique [0002] Introduction: Tubular (also known as shell and tube, heat exchange tube) heat exchanger is the most typical partitioned wall heat exchanger. leading position. A high-temperature steam tube heat exchanger is mainly composed of a shell, a tube bundle, a tube sheet, and a head. The shell is mostly circular, and parallel tube bundles are installed inside. The steam tube heat exchanger can not only meet the production needs, but also realize energy recovery and comprehensive utilization, play a role in saving energy and protecting the environment, and realize low-carbon life and sustainable development of enterprises. In the existing heat exchanger technology field, different grades of media are directly introduced into the same heat exchange space, such as the common incinerator waste heat boi...
