Problems solved by technology

The chemical raw material has strict requirements on storage and transportation. At present, the transportation of the chemical raw material is mainly carried out in tank containers or drums with thermal insulation and heating devices. The transportation efficiency is low. The use of railway tanker transportation can greatly improve the transportation efficiency and save transportation costs.
The existing tank cars with heat preservation and heating functions in China are mainly asphalt tank cars. Asphalt tank cars use built-in fire tube heating and external glass wool for heat preservation. The heating method and heat preservation performance cannot meet the shipping requirements of this chemical raw material; It is made of carbon steel, which is easy to rust and pollute the goods transported, and it is not suitable for the shipment of fine chemical raw materials
At present, it is still blank to transport this kind of chemical by railway tanker in China

Abstract

The invention relates to a railway tank truck with a heat-insulating structure. The railway tank truck comprises a tank, a heating device and a heat insulating device. The heating device and the heat insulating device are arranged on the outer surface of the tank. The railway tank truck is characterized in that the heating device comprises a steam heating sleeve and a steam heating control system, and the steam heating control system has a steam tube leading to the steam heating sleeve. The heat insulating device is provided with a heat insulating shell which is supported on the tank through a supporting ring, and a heat insulating layer is laid in a gap between the tank and the heat insulating shell. The railway tank truck is large in heating area and high in heating efficiency, the tank can be controlled in temperature and heated by the railway tank truck, and deterioration of goods caused by overhigh heating temperature is avoided. The heat insulating device is made of a novel heat insulating material and of an outer heat insulating shell structure, heat insulation of the tank can be realized, heat loss of media during transport can be reduced, and energy is saved.

Description

technical field [0001] A railway tank car with temperature control and heating function relates to a railway tank car with a heat preservation structure. Background technique [0002] Certain organic chemical and fine chemical raw materials are in a solidified state when the temperature is lower than 20°C, and can be turned back into a liquid state by heating. The heating temperature must be controlled in order not to affect its properties. The chemical raw material has strict requirements on storage and transportation. At present, the transportation of the chemical raw material is mainly carried out in tank containers or drums with thermal insulation and heating devices. The transportation efficiency is low. The use of railway tanker transportation can greatly improve the transportation efficiency and save transportation costs. . The existing tank cars with heat preservation and heating functions in China are mainly asphalt tank cars. Asphalt tank cars use built-in fire tu...
