The process has the advantages and the effects that the thawing speed is greatly increased through adopting the infrared radiation heating method, the construction cost of the process is reduced, the energy is saved, and the smooth production and the normal turnover of the vehicle can not be affected, and the infrared radiating heating device not occupies space, can be installed beside a current.
Description
Technical field
The present invention relates to a kind of method for rapidly thawing bulk freight vehicle, particularly a kind of method of using infrared radiation to thaw.
Background technology
At the vast northern area of China, winter climate cold, the bulk goods such as the haulage time of various types of vehicles transportation are longer, all can degree of one-tenth when arriving the destination unloading goods differently occurs and car body freezes together the situation (freezing car to call in the following text) that can't unload.Multifarious in the reality to the defreezing method that freezes car, the Mechanical Crushing that the heating that has is thawed, had, somebody worker's breaking method, but with regard at present used method, all exist disadvantage to some extent.Below be example just with the defreezing method of thermal power generation corporations' coaler, set forth and the nearest prior art of the present invention.Because winter, cold district constantly increased the demand of electricity and heat, hydroelectric generation has entered dry season again, thereby to provide fire coal to thermal power generation corporations sustainedly and stably be to satisfy the basic assurance of the people to electricity needs.Stipulate " large-size thermal power plant of severe cold area when railway comes coal to freeze seriously to be difficult to unload coal, should be provided with the facility that thaws " among " thermal power plant designing technique rules " DL5000-94 in principle.And what is called thaw facility at present domestic be exactly to build defrozing silo.And so-called defrozing silo is exactly can hold tens car bodies simultaneously and have the enclosure space of heating installation according to the thaw quantity construction of car of need, will freeze the traction of car group and make through six to eight hours heating to the storehouse and freeze car and thaw, and then carry out car unloading operation.General construction cost is up to several ten million yuan, and use cost is also very high, particularly its required time of thawing very long, influence is produced carries out normal turnover with vehicle smoothly; Simultaneously, the energy resource consumption of this method is also very high.
The content of invention
The objective of the invention is to provide that a kind of thawing rate is fast, thawing apparatus is cheap, energy consumption is low, and do not influence production carry out vehicle defreezing method with the normal turnover of vehicle smoothly.
The characteristics of technical scheme of the present invention are: at first, vehicle to be thawed is led to the thermal treatment zone, the both sides that promptly are heated vehicle in the thermal treatment zone are provided with the infra-red radiation electric heater unit, with this infra-red radiation electric heater unit vehicle is carried out radiation heating then, time is 5-15 minute, electrical power is 400-900KW, and the vehicle that will thaw involves the thermal treatment zone at last.
The described infra-red radiation electric heater unit of another characteristics of the present invention can also be arranged at around the vehicle.
The present invention has following advantage and technique effect: 1, owing to adopting the infrared radiation heating method to thaw, so thawing rate greatly improves.The mode of the Convective Heating of prior art is that heating source progressively heats self ambient air earlier, volumetric expansion after air is heated, the proportion come-up that lightens, heating source heats the heavier cold air of relative proportion again, the air themperature in space is risen, and the higher air of temperature with heat transferred by all objects of its parcel, these objects are heated.Build defrozing silo and utilize this principle exactly, its shortcoming is special-purpose storehouse and the heating equipment that needs to build sealing, drops into hugely, and ice-melt time very very long (6-8 hour), energy dissipation is serious, the use cost height.The mode of the Convective Heating of the energy transmission of infra-red radiation electrical heating method of the present invention and the mode of absorption and prior art is completely different, it need not add hot-air, but being passed air by infra-red radiation with the form of ripple, heat is directly delivered to car body surface, its temperature is risen rapidly at short notice, reach the purpose (5-15 minute) of quick ice-melt.The heat of infra-red radiation is to transmit with the form of ripple, thereby its heat waste in the process of transmitting is very little, simultaneously, has directionality owing to transmit, raying part car body steel billet temperature is risen rapidly, and by the conduction of heat of steel plate the whole locomotive body surface temperature is evenly transmitted, the car body temperature raise melted and frozen freight between freeze, reached the purpose of ice-melt.Thawing rate is compared with defrozing silo above 100 times.2, use this method construction cost low.Because this method need not to build large-scale defrozing silo, only need to build the infrared radiation device on the side, compartment in the open, its investment only is 1/tens of a defrozing silo.Also have short advantage of construction period simultaneously, general needed just can build up in tens days.3, energy-conservation.Because heating means of the present invention only with the heating of compartment steel plate, with the heat transferred goods, make the icing thawing between goods and the steel plate by the compartment steel plate, have just reached purpose as long as can unload.Need not the temperature in goods and compartment all to be heated to more than 0 ℃ as defrozing silo.So, greatly reduce energy consumption.What 4, do not influence production carries out normal turnover with vehicle smoothly.Because vehicle need not to enter defrozing silo again and thaws, but the operation of just can thawing in the way before entering unload zone, and thawing time is very short.So what do not influence production carries out normal turnover with vehicle smoothly.The present invention also has and does not take the place, unloads existing that fare is other can be installed; The advantage that use cost is low.
