Abstract

The utility model relates to a hot air drier which is composed of a box body, a U-shaped air flow passage, a blower, a dual-shaft extending motor, an oil pump, a burning chamber and a heat exchanger. The utility model is characterized in that the middle part of the U-shaped air flow passage of the box body is provided with the dual-shaft extending motor. One end of the dual-shaft extending motor is connected with the blower, and the other end of the dual-shaft extending motor is connected with the oil pump. The burning chamber is arranged on a horizontal position below the U-shaped air flow passage. A burner is arranged on the front end of the burning chamber. A tube group for the heat exchanger is arranged on the back end of the U-shaped air flow passage. An inlet of the lower end of the tube group is vertically connected with the outlet of the back end of the burning chamber, and an outlet of the upper end of the tube group is connected with a smoke exhaust port. A flow guide plate arranged on a back end plate on the box body guides heated air flows to flow out by passing through the periphery of the heat exchanger tube in an S shape. The drier can be widely used in fields, such as heating and drying in winter, dehumidifying in summer, etc.

Description

Air drier

The utility model relates to a kind of thermal device of Air boiler class, is a kind of air drier that a subthermal energy is directly changed into hot-air specifically.

In fields such as Ship Building and Repairing, construction, finishing application, warmhouse booth, tall building, the commercial Room, car park or garage, storage storehouse, apartment, hotels, warming, dehumidifying in rainy season use indirect heat energy converting to hot air to heat or dehumidify usually, as with electric heating, vapour heat or burn the charcoal heating, these class methods not only heat exchange efficiency are low, equipment is clumsy, heating power is little, and energy consumption cost is all very high, is unsuitable for modernization industry needs.

The purpose of this utility model is to overcome weak point of the prior art, and a kind of modernized air drier of full-automatic, high-power, high heat exchange efficiency is provided.

The utility model can be realized by following technical proposals:

This air drier is by casing, blower fan, twin shaft is stretched motor, oil pump, the combustion chamber, burner, the U-shaped air flow channel, heat exchanger is formed, it is characterized in that position that casing top U-shaped runner vacates installs twin shaft and stretch motor, motor one end connects oil feed pump, the other end connects the blower fan wind wheel of U-shaped runner arrival end, the combustion chamber is contained in the lower horizontal position in the U-shaped runner, burner and combustion chamber are contained in the front end of combustion chamber coaxially, the Tube Sheet of Heat Exchanger group lower end that is positioned at the U-shaped runner connects with the combustion chamber is vertical, the upper end connects with exhaust opening, be provided with deflector at box back, the S-shaped exchanging air of walking around of steering current; The pipe group that heat exchanger is made up of thin-walled heat-resistance stainless steel pipe is equipped with snakelike choked flow bar in the pipe.

The utility model has the advantages that:

1, volume is little: the volume of 90Kw air drier has only 0.875m ³

2, in light weight: the body weight of 90Kw air drier has only 180Kg;

3, heat exchange efficiency height: the thermal efficiency that uses light diesel fuel can reach 85-90%;

4, fuel consumption is low: use a light diesel fuel oil consumption 105CC/KW-h in winter;

5, use cost is low: calculating by China's electricity charge and oil price, only is 20% of electrical heating type air drier expense;

6, heat up rapidly: can reach the control temperature soon after the start, generally have only about 30 seconds.

Fig. 1 is the air drier structural representation

Now the utility model is further described in conjunction with the accompanying drawings: with reference to Fig. 1, the front end of casing 1 is provided with air inlet 1, blower fan 2 drives with stretch motor 3 with a twin shaft with fuel pump 4, blower fan is introduced outside air after wind wheel 2 pressurizations from air inlet 1, send to dirty from the U-shaped runner I district of casing, main flow partly flows through the periphery of combustion chamber barrel 7 through II district horizontal direction, after the S-shaped tube wall periphery of flowing through Tube Sheet of Heat Exchanger group 8 of the guiding of deflector 11 drains into the heat supply space from exhaust outlet 12; In addition, also have one tributary air to enter the Adjustable air port 6 of burner 5 through combustion chamber air inlet 14 from the I district, oil/gas mixing ratio burning with the best, flame in combustion chamber 7 fully the hot gas after the burning 7 rear end enters Tube Sheet of Heat Exchanger group 8 inside from the combustion chamber, combustion gas is subjected to the effect of choked flow bar 10 in the heat exchange tracheae, then slowly flow, fully drain into chimney breast from exhaust opening 9 again after the heat release; Fuel oil makes fuel-oil atmozation through the nozzle 17 that oil pump 4 is sent to burner 5, and the effect that the flame after high-voltage arc igniter 18 ignites is subjected to eddy flow tray 16 makes flame be the whirlwind shape column of flame to mix with auxiliary air and reach abundant burning.

Claims

1. air drier, it is by casing, the U-shaped air flow channel, ventilation blower, oil pump, twin shaft is stretched motor, the combustion chamber, heat exchanger is formed, it is characterized in that middle part that casing middle part U-shaped runner is vacated installs a twin shaft and stretch motor, one end connects oil feed pump, the other end connects the wind wheel of blower fan, the combustion chamber is arranged on the lower horizontal position in the U-shaped runner, burner then with the coaxial chamber front end that is contained in of combustion chamber cylinder, the Tube Sheet of Heat Exchanger group lower end that is positioned at the U-shaped runner connects with the combustion chamber is vertical, the upper end connects with exhaust opening, be provided with deflector at box back, the S-shaped heat exchanger of walking around of steering current.

2, air drier according to claim 1 is characterized in that heat exchanger is that one group of thin-walled heat-resistance stainless steel pipe constitutes, and is equipped with snakelike choked flow bar in the pipe.
