Description

The utility model relates to the field of loading and unloading and can be used to heat frozen goods in a car before unloading them.

The prior art system for defrosting wagons, including a tunnel made of metal frame with wall sheathing from sandwich panels with insulation and an appropriate protective coating, a drainage system for collecting and discharging wastewater. Each section of the system is equipped with gas infrared burners, exhaust gas exhaust fans, air supply vents for air heating of the bottom of the car, a column with an air channel. The car is thawed in the following directions: top, side and bottom using special-purpose industrial infrared heaters, which, if necessary, can be equipped with an air-heating system using heat-generating equipment. This tunnel is equipped with thermal curtain systems to prevent the supply of cold air to the defrost area, composition position sensors that regulate the inclusion of the system when entering the car defrost zone, and an automatic control system. The number of simultaneously defrosting wagons is 21 wagons (see http://www.smartflam.by/biblioteka/sistema-razmorozki-vagonov.html).

Known film defrosting wagons in an inert gas environment, selected as the closest analogue, using infrared gas burners of a dark spectrum of radiation with forced air supply for the combustion process and including a heater, equipped at the ends with air curtains and divided into sections according to the number of defrosted cars, each section includes separate lateral and lower heating systems, and the lower heating system is configured to use Teplyakov heated air and combustion products from the infrared burner from the roof space fed by fans arranged in the space under the roofing Teplyakov, the column with the air passage through the two nozzles, the ends of the carriage, and a control system (see.

http://www.gogas.su/File/Ustanovki_dlya_razmorajivaniya_vagonov.pdf).

The number of infrared emitters in the known installation located on the side walls of the greenhouse is six. In this case, thawing of the side walls of the car occurs due to infrared radiation of 4 rows of emitters. And the lower two rows of emitters located on the side walls of the greenhouse are designed to heat the bottom of the car. According to the authors of the well-known installation, the end walls of the car and the bottom are additionally heated due to the created convective flow supplied from under the roofing space through a column with an air channel by special heat-resistant fans. The distribution of the jet along the bottom of the car is due to the guide nozzles located at the ends of the car. Infrared emitters incorporate a mixing burner with forced air supply for combustion. The infrared emitters in the known installation are 2-stage, divided into 2 groups according to the height of the tunnel, each of which is separately regulated. In addition, all burners are paired and turned on and off in pairs.

All gas pipelines, fans, fittings, etc. located outside the warmhouse in the insulated compartment.

These insulated compartments are located opposite each column of the section, and it is in them that the burners of infrared emitters, gas fittings and electronic means of data transmission are located. To provide combustion air, to maintain a normal temperature in these compartments after hours and to create a backwater, an additional gas air heater is provided in them. In this gas air heater, the air is heated in a stainless steel heat exchanger. The gas air heater has a free head of "400 Pa and is connected by air ducts to supply air to each of the compartments. The same air serves to cool pyrometers and photocells, as well as to prevent dust accumulation on their surface. The weight of the heater is approximately 400-450 kg.

The control system used in the known installation, using pyrometers, tracks both the temperature of the wall of the car and the temperature of the receiver, but indirectly. In accordance with the readings of the pyrometers, the switching frequency of the infrared emitters of a particular group is regulated. In addition, the control system monitors the temperature of the medium in the recirculation channel to control and limit the temperature of all the same heat-sensitive elements of the car. Thus, in each section of the known system provides its desired temperature, as the walls of the car, and brake cylinders, receivers, hoses, etc. The control system of the known installation is equipped with photocells to control the presence of a car in each section. Key features of the fan control system include:

- automatic inclusion of fans by the signal of thermostats from each post, at an ambient temperature in the upper zone of the PRV above 50 °;

- forced inclusion of remote fans from the control room or in place;

- forced shutdown of remote fans from the control room or locally.

However, the absence in the known installation of an independent system of the upper heating of the cargo in the car, located above the upper surface of the cargo, and the use for heating the upper layer of only the air temperature created in the heaters by heated air masses, significantly reduces the intensity of the process of thawing the frozen cargo from the side of its open surface in the carriage. Thus, the known system does not have a fast enough process of defrosting the cargo.

In addition, the location of the air ducts for recirculating hot air from under the roofing space in the supporting columns of the greenhouse, opposite each column of the section where the insulated compartments are located, can lead to overheating and fusion of the burner automation located in the insulated compartments. In addition, the channels located in the columns of the known installation have a small cross section, which does not ensure the creation of a sufficient air flow supplied under the bottom of the car. Thus, the known system is not equipped with a sufficiently effective system of lower heating of the cargo from the bottom of the car, which generally makes the known system is not sufficiently effective.

The presence of insulated compartments in which burners of infrared emitters, gas valves and electronic means of data transmission are located, and the use of an additional gas air heater to maintain a normal temperature in these compartments after hours, significantly complicates the known design, and can also lead to poisoning or even death staff during the commissioning, as in the confined space of the insulated compartment can accumulate both carbon monoxide and natural gas, and leave then the room staff quickly enough is not possible. The inability to quickly leave the premises of the insulated compartment is due to the fact that access to it for servicing the equipment and burners located in it is provided in the form of a narrow manhole in the lower part of this compartment, into which the service specialist must climb through.

In a known design, the car’s lower heating system is not effective, since the hot air leaving the guide nozzles

located only at the ends of the car, it is not able to warm the bottom of the car

along its entire length, since hot air after exiting the nozzles extends along the bottom of the car only a small distance, since almost immediately the whole goes up, passing the bottom of the car.

In addition, the known system is inconvenient to maintain, due to the need to climb into a small hole - the only access point to the insulated compartment located at the bottom of this compartment and having small dimensions. Moreover, especially in snowy winters, this hole has to be dug up from the snow. And taking into account the fact that each car is serviced by two warm compartments, when placing a large number of defrosted cars in the teapot, in order to provide access to each of the insulated compartments, the use of additional maintenance personnel will be required.

In addition, the use in the known system of 2-stage infrared emitters, divided into 2 groups according to the height of the tunnel, each of which is separately regulated and, in addition, all burners are paired and turned on and off in pairs, also reduces the efficiency of the system, due to that turning off two twin burners at once, instead of one, the heating of the load on a larger surface and a larger volume is reduced.

Thus, the technical result, the solution of which the claimed solution is directed, is to eliminate the shortcomings of the closest analogue, namely: increasing the efficiency of the claimed device, which allows to intensify the process of defrosting the cargo, improving the ease of maintenance, as well as improving the safety of both the maintenance staff and the device as a whole .

The specified technical result is achieved by the fact that the section of the heater, equipped with air curtains from the end sides, for defrosting a frozen cargo in the car, including separate side and bottom heating systems, the side heating system being made in the form of infrared gas burners of a dark spectrum located on the side walls of the heating section. radiation with forced air supply for the combustion process, the lower heating system is configured to use heated air and products with screaming from infrared burners from under the roofing space of the section of the greenhouse supplied by the fan to the nozzles in the lower part of the carriage along the vertical channel, as well as the control system, according to the utility model, it additionally contains a separate system for the upper heating of the frozen cargo located along the upper surface of the cargo of the defrosted carriage, equipped with an infrared gas burner of a dark emission spectrum with forced air supply for the combustion process and an air duct, all gas burners and sections are made with the possibility of self-intake of air from the outside of the section of the hothouse, the lower heating system is made in the form of a collector with nozzles located along the central part of the railway sleepers along the entire length of the carriage, and the shape of the lower part of the collector is made in the form of a variable section of the central part of reinforced concrete sleepers and the nozzles are located along the upper flat surface of the collector in two rows in pairs in a checkerboard pattern with the formation of a gap between the rows, the feed is heated of air from under the roofing space to the collector of the lower heating system is carried out along a vertical channel made in the form of an air duct located on one of the sides of the section of the heating device, while the lower part of the air duct is brought to the collector in the rail-rail space of the car underground.

At the same time, six burners are installed on each side of the gondola.

In addition, it is additionally equipped with a microprocessor control system, a gas control system, and a system for supplying and distributing air and exhaust gases.

Also, the section of the teplyak, equipped with air curtains on the front sides, for defrosting a frozen cargo in the car, contains an additional pyrometer to control the temperature of the cargo from above, and the temperature of the brake cylinder and bearings is controlled by three pyrometers, two of which are installed with the ability to measure the temperature of the car's brake system along its edges, and the third - with the ability to measure the temperature of the brake system of the car in the middle of the car.

And the infrared burners of the side heating system are located in separate modules with the possibility of servicing them from the outside of the heat section.

It is additional equipment of the claimed design with an upper heating system for the frozen cargo in the car, located along its upper surface, equipped with an infrared gas burner of a dark emission spectrum, with forced air supply for the combustion process and an air duct, the implementation of all gas burners of the system with the possibility of independent air intake from the outside sides of the heating section, equipping the bottom heating system of each car with an air supply duct from under the roof space va teplika, the location of the lower part of each duct for each car underground under the rail tracks, the laying of collectors with nozzles of the lower heating system, is tight on the railway sleepers, according to the applicant, it allows to achieve the claimed technical result.

Thus, the presence of a top heating system for the frozen load of the carriage, consisting of burners located above the upper surface of the frozen load of the carriage, allows the coolant to also be supplied to the upper part of the carriage and, thus, to intensify the process of thawing the frozen load from the side of its open surface in the carriage. At the same time, the presence of an overhead heating system allows to accelerate the process of defrosting a frozen carriage load by 20-25%.

The implementation of all gas burners of the claimed device with the possibility of independent air intake precisely from the outside of the heating section allows simplifying the section design, since it eliminates the need for insulated compartments providing the device with combustion air and additional gas air heaters, and also eliminates the need for forced air supply to insulated compartment, which ultimately simplifies the inventive device and, as a result, improves service conditions, as well as lower Expects operational and financial costs.

The implementation of the lower heating system of the carriage section in the form of a collector with nozzles located along the central part of the railway sleepers along the entire length of the car, with the shape of the lower part of the collector repeating the shape of a variable section of the central part of reinforced concrete sleepers and the nozzles arranged in two rows along the upper flat surface of the collector pairwise in a checkerboard pattern, with the formation of a gap between the rows, improves the performance of the inventive device. This is due to the fact that this implementation and placement allows you to expand the range of serviced cars and rail tracks, in particular, allows you to use the inventive device when applying widely used currently concrete sleepers, with a recess in its Central part. And the claimed placement of nozzles on the manifold allows the use of the inventive device for defrosting freight cars having low-lying suspension elements of the car.

The implementation of the supply of heated air from under the roofing space to the collectors of the lower heating system of each car via vertical channels made in the form of separate air ducts for each car located on one of the sides of the section of the teapot simplifies the claimed design by reducing the number of channels for supplying hot air from under the roofing space, as well as reducing the number of fans supplied with hot air. This in turn provides simplification of the design as a whole. In addition, it is the claimed implementation of the lower heating system of the claimed design that increases the efficiency of cargo defrosting, since the air ducts have a sufficient volume of the cross-section, which ensures the creation of an effective air flow supplied under the bottom of the car. In addition, the implementation of vertical channels in the form of air ducts completely eliminates the negative impact of high temperatures on automation and burners, since the air ducts in the inventive device are located separately from the locations of the automation and gas burners, which increases the safety of the inventive device.

Placing the lower part of the duct underground under the railroad tracks, providing access to hot air from under the roofing space, in addition to not cluttering the working space of the heating section, also ensures that the temperature of the hot air is maintained, which in turn also improves the efficiency of the claimed device.

And the laying of collectors with nozzles of the lower heating system, on the railroad ties, ensures guaranteed heating of the bottom of the car along the entire length, which significantly increases the efficiency of the inventive device and reduces the time of cargo defrosting.

Additional equipment of the claimed device with a microprocessor control system, a gas control system, and a system for supplying and distributing air and exhaust gases, allows the process of defrosting ore in automatic mode for different programs for any type of cargo, which significantly increases the efficiency of servicing the claimed device. Manual mode is provided, which is used during commissioning and when testing individual systems.

The presence of an additional pyrometer for monitoring the temperature of the cargo from above, and monitoring the temperature of the brake cylinder and bearings with three pyrometers, instead of two, as in the closest analogue, two of which are installed with the ability to measure the temperature of the brake system of the car along its edges, and the third with the ability to measure temperature the brake system of the car in the middle of the car, allows you to get more information about the temperature of the cargo in the defrosted car, which provides an opportunity to assess the condition e defrosted cargo in more places and, therefore, at a more optimal time, decide on the need to continue warming up the cargo or its end. This in turn increases the efficiency of maintenance of the claimed device.

The location of the infrared burners of the lateral heating system in separate modules with the possibility of servicing them from the outside of the teapot further improves the service conditions of the system and also increases the safety of the system as a whole. This is ensured by the fact that the individual modules for the location of the burners, in addition to their location on the outside of the heater, have convenient doors that open outward, providing easy access for maintenance personnel. At the same time, the doors are equipped with ventilation openings, such as "blinds", which exclude the accumulation of carbon monoxide or natural gas in the module, which makes the modules safe for maintenance personnel and the system as a whole.
