Railway tank car used for transporting organic chemical raw materials

Abstract

The invention discloses a railway tank car used for transporting organic chemical raw materials. The railway tank car comprises a car frame and a tank body which are detachably connected, a heating pipe is welded on the outer side wall of the tank body, a heat insulating layer is wrapped outside each of the tank body and the heating pipe, a windproof cover is wrapped outside each heat insulating layer, and a remote monitoring device is arranged on the tank body. The railway tank car has the advantages that heat insulation of transported media can be realized effectively, and setting time of the transported media can be increased greatly, so that cost needed for heating is reduced. The railway tank car has a remote monitoring function, so that a user can know transportation conditions of the media at any time; the tank body is easy to demount and convenient to maintain.

Description

technical field [0001] The invention relates to a railway tank car used for transporting organic chemical raw materials. Background technique [0002] 1,4-Butanediol (BDO for short) is an important organic chemical and fine chemical raw material. In recent years, my country's BDO production capacity has increased significantly. In 2009, the new production capacity was 215,000 tons / year, reaching 424,000 tons / year In 2011, my country's BDO production capacity was 504,000 tons per year, accounting for 25.28% of the world's total production capacity, which led to a sharp increase in BDO transportation. [0003] BDO is a colorless viscous oily liquid with high added value. It has high requirements on the cleanliness of the transport carrier and must not contain impurities such as rust. BDO has a relatively high relative density of 1.0171 and a high melting point of 20.1°C. Crystallization will occur below this temperature. If crystallization occurs during transportation, it nee...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no railway tank car specially used for BDO transportation in China. General products such as automobile tank cars or tank containers (ISO-TANK) are generally used to transport BDO in China. Among them, tank containers are general-purpose products for transporting chemical products. When storing and transporting BDO, some functions are not used, and the functions of tank containers are not fully utilized, resulting in a great waste of resources
