The invention relates to a low-temperature tank truck. The low-temperature tank truck comprises a storage tank, a vaporizer and a defrosting unit; the vaporizer communicates with the storage tank; thedefrosting unit comprises a high-pressure gas source, a connecting pipe, a control valve and a blowing pipe the high-pressure gas source, the connecting pipe and the blowing pipe sequentially communicate; the control valve is arranged on the connecting pipe; and the blowing pipe is arranged close to the vaporizer, and a plurality of gas flow holes are formed in the blowing pipe and face the vaporizer. According to the tank truck, the defrosting unit is additionally arranged on the vaporizer of the tank truck; the blowing pipe is arranged close to the vaporizer and matched with the gas flow holes in the blowing pipe, and the defrosting operation is conducted on the vaporizer through high-pressure gas provided by the high-pressure gas source; and when the surface of the vaporizer frosts dueto long-time work, the control valve can be opened to enable the high-pressure gas in the high-pressure gas source to be blown to the vaporizer at a high speed through the gas flow holes, so that frost covering the surface of the vaporizer is blown off, the function of defrosting the vaporizer is achieved, and the vaporization effect of the vaporizer is effectively guaranteed.

    本发明涉及一种低温罐车,该低温罐车包括储罐、汽化器及除霜单元;汽化器与储罐相连通;除霜单元包括高压气源、连接管、控制阀和吹扫管;高压气源、连接管和吹扫管依次相连通;控制阀装设于连接管上;吹扫管靠近汽化器布置,吹扫管上开设有若干气流孔,气流孔朝向汽化器布置。本发明在罐车的汽化器上增设除霜单元;利用吹扫管靠近汽化器布置,并配合在吹扫管上的气流孔,利用高压气源提供的高压气体对汽化器进行除霜操作。当汽化器因长时间工作而表面结霜时,可开启控制阀使高压气源内的高压气体经气流孔高速地吹向汽化器,从而将覆盖在汽化器表面的霜吹落,以实现对汽化器除霜的功能,进而有效地保证汽化器的汽化效果。
