Description

A kind of heating equipment for flue-cured tobacco room

technical field

The utility model belongs to baking equipment, in particular to a heating equipment for a tobacco curing room.

Background technique

Flue-cured tobacco is a special product, which is the primary processing of mature tobacco leaves in specific baking equipment to form a specific internal quality and dry to fix its quality. In the flue-cured tobacco preparation process, a series of biochemical changes will occur inside the tobacco leaves, and at the same time, they will be dehydrated and dried. This process consumes a lot of energy. The general way of energy consumption is: heat energy is generated by heating elements, and then the air in the barn is heated by heat dissipation equipment. The hot air does work on the tobacco leaves to increase the temperature of the leaves, and the water is lost to the surface of the leaves, and then vaporized into the air, forming damp heat The air is exhausted outside the flue-curing room, and the continuous heat makes the leaves high temperature and dry. In practice, the heat consumption at least includes: the temperature rise of tobacco leaves and the heat consumption of water vapor vaporization, the heat consumption of hot and humid air discharged from the exhaust port after the cold air entering the flue-curing room is heated, the heat consumption of the maintenance structure of the flue-curing room and the tobacco hanging rack, etc.

The heat consumption in the tobacco leaf curing process is divided into effective heat consumption and ineffective heat consumption. Effective heat consumption is mainly used to promote the evaporation and removal of moisture in tobacco leaves. Generally speaking, the actual heat required to remove 1Kg of water during the baking process is 2.778-4.505 times the theoretical one. The thermal efficiency of the flue-cured tobacco room is 22.2%-36.0%. Ineffective heat consumption is mainly heat loss.

Most of the tobacco leaf production in my country is flue-cured tobacco. In the past, most flue-cured tobacco in my country used coal for curing, and the average coal consumption for drying 1Kg of tobacco leaves was 2.0-3.0Kg, while the theoretical coal consumption was only about 0.8Kg. Coal resources are limited, not inexhaustible, and inexhaustible. In order to improve energy utilization, electric heating elements have been used to replace coal in the market to solve the problem of low energy utilization due to incomplete combustion of coal. . However, the heat conversion rate of the electric heating element is high or low, and it faces the problem of excessive installed capacity. Obviously, how to improve the utilization rate of energy in the process of flue-curing tobacco and provide a kind of flue-cured tobacco curing equipment with renewable energy and energy saving is a problem to be solved urgently by those skilled in the art.

Utility model content

The purpose of the utility model is to provide a heating device for a flue-cured tobacco room with higher heat energy utilization rate and energy saving.

The technical scheme that realizes the utility model object to adopt is as follows:

The heating equipment of the flue-cured tobacco room provided by the utility model includes a methanol burner, a combustion pipe, a radiator, and an exhaust pipe; the methanol burner and the exhaust pipe are respectively arranged at two ends of the combustion pipe, and the radiator It includes several tubular vacuum medium radiators, one end of which is inserted into the combustion tube.

The vacuum medium radiators are arranged in a V shape.

The vacuum medium radiator includes a sealed metal tube filled with heat conduction medium through vacuum, and a plurality of metal cooling fins are arranged on the metal tube.

The combustion tube is provided with a bracket.

The beneficial effect of the utility model: due to the use of methanol burner as the heat source, the heat conversion rate can reach more than 80%, and methanol belongs to renewable green energy, which meets the requirements of environmental protection. Compared with the existing coal and electric ovens, it has heat energy The utilization rate is higher, the energy saving is obvious, and it is not affected by the large installed capacity of the electric oven and the limitation of electricity consumption.

Further illustrate the technical scheme of the utility model below in conjunction with accompanying drawing.

Detailed ways

Referring to Fig. 1-2, the heating equipment of the flue-cured tobacco room includes a methanol burner 2, a combustion pipe 6, a radiator, and an exhaust pipe 8; the methanol burner 2 is installed on the conical pipe 3 at one end of the combustion pipe 6. The exhaust pipe 8 is installed on the other end of the combustion pipe 6, and the radiator includes a plurality of tubular vacuum medium radiators, and the vacuum medium radiator includes a sealed copper tube 4 filled with a heat-conducting medium through vacuum, and the copper tube 4 is provided with A plurality of aluminum cooling fins 5 , one end of the copper tube 4 of the vacuum medium radiator is inserted into the combustion tube 6 , the vacuum medium radiator is arranged in a V shape, and the combustion tube 6 is provided with a bracket 7 . the

working principle:

The methanol burner 2 is installed outside the flue-cured room, and the heat dissipation system composed of the vacuum medium radiator copper tube 4, the combustion pipe 6 and the fan 9 is installed in the heating room of the flue-cured room, and the exhaust pipe 8 leads to the outside. The methanol burner 2 is supplied with methanol from the fuel pipe 1, and sprays flames into the combustion pipe 6 after ignition. The high-temperature hot air will heat the copper pipe 4 inserted into the combustion pipe 6, and the liquid heat transfer medium in the copper pipe 4 will absorb heat and then vaporize. Rising along the copper tube, under the cooling effect of the fan 9, the vaporized heat transfer medium provides heat to the air through the heat exchange of the heat dissipation fins 5, and at the same time condenses into a liquid medium and flows back to the bottom of the copper tube 4, repeating and continuously circulating to the flue-cured tobacco room to provide the required hot air. The exhaust gas after combustion is discharged to the outside by exhaust pipe 8.
