Abstract

The invention discloses a coal and ore microwave thawing device which is composed of a freight train carriage (1), a platform positioning system (2), a thawing room (3), a water screen microwave sealing device (4), a microwave shielding sealing device (5), a dehumidification system (6), a microwave energy feedback system (7), a microwave cooling system (8) and a control system (9). Firstly, coal and ore absorb microwave and emit heat, an ice layer which contacts with the coal and the ore melts into water, the water fast heats up due to the fact that the microwave absorption capacity of water is very strong, then other ice layers are fast melted, and therefore the effect of fast thawing is achieved. According to the coal and ore microwave thawing device, a carriage is directly utilized to be a microwave heating excitation chamber for heating the coal and the ore, speeds of thawing the coal and the ore are fast, thawing time of the coal and ore microwave thawing device is over 50 times than that of a traditional thawing way, energy is saved by 70%, and therefore the coal and ore microwave thawing device is especially suitable for thawing and handling of frozen coal and ore of power plants and marine terminals in cold areas.

Description

technical field [0001] The invention relates to a thawing device, in particular to a coal and ore microwave thawing device which uses microwaves to thaw frozen coal and ore with good microwave coupling performance. Background technique [0002] The temperature in winter in Northeast China and Northwest China is low, at minus 20-30°C, and outdoor materials are frozen. The Northeast and Northwest are my country's energy industry bases, both of which are dominated by thermal power generation. Coal and ore transported by train in winter are all frozen into one piece during transportation, and need to be thawed when they are unloaded at power plants or foreign shipping terminals. The current thawing method is: build a very long heat preservation room, pull the coal and ore carriages to be thawed into the heat preservation room, pass hot air through the room to make the temperature of the heat preservation room higher than 100°C, and keep the coal and ore in the carriage in the h...
