Tank container steam heating device

Abstract

The invention belongs to a container steam heating device. In order to solve the technical problem that an extra-tank heating system of a tank container in the prior art is low in heating efficiency and insufficient in heating balance degree, and condensed water generated by a heating pipeline in a low-temperature environment is poor in circulation, a tank container steam heating device is provided. The tank container steam heating device comprises an arc-shaped shell and an arc-shaped heating cover plate, the shell is arranged outside the heating cover plate in a sleeving mode, a cavity is formed between the shell and the heating cover plate, a steam inlet channel, a steam outlet channel and a plurality of cavity partition plates are arranged in the cavity in the circumferential direction, the plurality of cavity partition plates are located between the steam inlet channel and the steam outlet channel to divide the cavity into a plurality of heating areas which sequentially communicate with one another, steam passing holes and condensed water passing holes are formed in the inner side of the steam inlet channel, steam passing holes and condensed water passing holes are formed in the cavity partition plates, steam passing holes and condensed water passing holes are formed in the inner side of the steam outlet channel, and condensed water discharge ports are formed in the outerside of the steam outlet channel.

Description

technical field [0001] The invention belongs to a container steam heating device, in particular to a tank type container steam heating device. Background technique [0002] Tank containers are used more and more widely around the world. As the main carrier of multimodal transport, various goods transported must be heated to a certain temperature before loading and unloading. The heating method of the goods is generally divided into tank heating system and external tank heating system. [0003] Once the heating system in the tank leaks, it will cause the goods to leak into the heating system, which will block the pipeline and make the heating system invalid, and the goods shipped are easy to adhere to the heating system in the tank, making it difficult to clean; It will cause medium pollution, easy inspection and maintenance and other advantages are widely used. [0004] The existing heating system outside the tank mostly uses a heating jacket with a wrap angle of about 250...

AI Technical Summary

Problems solved by technology

[0005] The present invention solves the low heating efficiency and insufficient heating balance of the external tank heating system of the tank container in the prior art, as well as the poor flow of condensed water generated by the heating pipeline in the low temperature environment in winter, which may cause the heating pipeline to be blocked To solve the technical problems of partial corrosion of pipes and pipelines, a steam heating device for tank containers is provided
