Description

Electric fan of high pressurized steam heater having the fuction of extracting plant juice

The present invention relates to a high-pressure steam electric hot air heater having a wood vinegar extracting function, and more particularly, to prevent global warming due to exhaust gas and to protect the environment, an electric hot air fan and a safe crop that do not generate carbon dioxide because they do not burn petroleum fuel. It is to provide a high-pressure steam electric hot air heater that combines wood vinegar extract function to easily extract wood vinegar, which is an alternative means of pesticide, in order to aim to produce pesticide-free, which is indispensable for organic farming.

As a conventional hot air heater, a means for heating the air blown by burning petroleum-based fuel and supplied to the blower to change it to warm air is common.

Also, the extraction method of wood vinegar is carbonized by combustion, so that the wood vinegar contained in the cracked gas generated in the process of raising the temperature in the kiln and carbonizing raw materials such as wood and sawdust is cooled in a flue collecting smoke. The method of recovering redwood vinegar has been put to practical use.

For example, in a hot air fan, kerosene, diesel oil, heavy oil, etc. are burned using a burner to warm them by heat exchange, and since carbon dioxide is discharged during combustion, it is possible to prevent occurrence of oxygen deficiency and carbon dioxide poisoning in a sealed state. Ventilation is necessary.

Therefore, ventilation is required for ventilation, and about one third of the thermal calories are lost in this exhaust process.

As for the extraction of wood vinegar, most of the extraction methods produce charcoal. Therefore, the wood vinegar is collected as a by-product by collecting smoke containing organic components contained in the decomposition gas generated during the carbonization of wood, which is a charcoal. Extraction of wood vinegar.

Therefore, since it is not a charcoal kiln for the purpose of extracting wood vinegar for equipment and equipment, it is a reality that little consideration has been given to productivity, quality and stable supply in terms of wood vinegar extraction.

In other words, for the production of wood vinegar, the technology for stable supply and economic production has not been established or known.

Therefore, the present invention removes carbon dioxide, a global warming factor caused by warming by combustion of petroleum fuel, in the clean and safe supply of warm air supply and wood vinegar, and removes one third of the waste heat lost by exhaust from ventilation. By improving the thermal efficiency, it is also contributing to the low-energy policy that is being implemented as a national policy.

In addition, by providing far-infrared warm air, which is effective for purifying air in enclosed spaces, it aims at the safety of closed room operations and the promotion of the growth of crops grown.

For the extraction of wood vinegar, wood vinegar is used as an alternative means to reduce the cost of introducing equipment and to abolish the use of pesticides, which is a problem in promoting organic farming, by utilizing the electric heater attached to the hot air heater. The present invention has been completed with the technical problem of the present invention by providing a high-pressure steam electric hot air heater having a function of extracting wood vinegar for the purpose of contributing to the promotion of organic agriculture by providing a method for easy and cheap manufacturing.

The electric heater (1) of the present invention connects the water intake pipe (4) in the water supply and cooling tank (3) to supply water and electricity heated to a constant temperature by heat exchange in the water supply and cooling tank (3) to supply water. Water is supplied to the electrothermal boiler (2) as a heat source using a water supply pipe (5) and heated.

The high temperature saturated steam generated by the heating of the water by the heat transfer in the electrothermal boiler 2 is supplied to the high pressure unit tank 7 installed in the electric hot air fan 1 by using the steam supply pipe 6, By using the amplification effect by raising the temperature of the saturated steam and then supplied to the heat exchange unit (8) to provide a heat source for generating hot air.

A blower 9 is installed at the rear side of the electric hot air fan 1 to blow air forward to pass heat inside the heat exchange unit 8 so as to perform heat exchange with a blown air through a heat source having saturated steam. That is, the warm air is blown to the outside through the front hot air nozzle 10 to heat a specific room.

After performing heat exchange by air blown through the heat exchange unit 8, the cooled saturated water vapor is converted into coagulated water and returned to the water supply and cooling tank 3 through the coagulated water drainage pipe 28 to circulate as electricity. It is used as saturated steam through. The on / off valve 32 is installed on the coagulation drain pipe 28 side to close the on / off valve 32 on the coagulation drain pipe 28 side when the saturated water vapor is to be sent to the pressure-resistant mixer 11 described later.

A great feature of the electric hot air blower (1) provided by the present invention is the hot air blown by the hot air having a far infrared, high pressure unit tank for the far-infrared of the air blown from the blower (9) via the heat exchange unit (8) (7) and the heat exchange unit (8) installed therein and the inner surface of the main body of the electric heater (1) are coated with a germanium-based paint (not shown).

Far infrared rays due to frictional action generated when the air blown by the blower 9 passes through the inside of the main body of the electric hot air fan 1 coated with germanium, the high pressure unit tank 7, and the inside of the heat exchange unit 8. Far-infrared warm air is supplied to the inside of a building such as a plastic house, which is converted into a warm air and is passed through the hot air nozzle 10 to install the electric hot air fan 1.

On the other hand, the present invention by connecting the pressure-resistant mixer (11) with a separate steam supply pipe (27) together with the electric hot air heater (1) and the electric boiler (2), the selected saturated water vapor to the pressure-resistant mixer (11) for wood vinegar solution You can perform the extraction function,

That is, the present invention carbonizes sawdust, which is a raw material of wood vinegar extract, by using hot saturated steam generated by heating water in the electrothermal boiler 2 for wood vinegar extract, and is included in the decomposition gas generated in the carbonization process. The wood vinegar, which is an organic component, is recovered to be extracted together with the exhaust of saturated steam.

To this end, as shown in FIG. 3, a raw material inlet 12 through which the sawdust, which is a raw material of wood vinegar, can be introduced into the pressure resistant mixer 11, is formed in the upper portion of the pressure resistant mixer 11, and an input hole is provided in the raw material inlet 12. The manual valve 13 is installed to selectively close the raw material inlet 12.

In addition, the carbonization material outlet 14 and the recovery pallet 31 are respectively provided at the lower portion of the pressure resistant mixer 11, and the inside of the pressure resistant mixer 11 is driven by a stirring electric motor 16 capable of speed control. To be able to axially install the stirring shaft (30) having several stirring blades (15).

One side of the pressure-resistant mixer 11 may be connected to the water supply and cooling tank 3 by connecting the steam exhaust port 17 to the pressure reducing pipe 23 so that the saturated steam in the pressure-resistant mixer 11 may be first cooled. The water supply and cooling tank 3 which performs the primary cooling function is connected to a cooling and recovery tank 24 having a cooling fan 29 to cool the saturated water vapor to secondary water so as to be immersed in the saturated water vapor. It is possible to recover the contained wood vinegar, the cooling and recovery tank 24 is forced to supply air through the blower duct 26 from the blower (9) of the electric warmer (1) at the same time cooling by air cooling method It was made possible.

When extracting wood vinegar using saturated steam from sawdust or the like using the pressure mixer 11, the sawdust is introduced into the pressure resistant mixer 11 through the raw material inlet 12, and then the inlet manual valve 13 is operated to the closed side. And the pressure resistant mixer 11 is switched to a sealed state.

At this time, the closed state of the carbonization material outlet 14 side after carbonization is also confirmed. When the sawdust input operation and the pressure-resistant mixer 11 are closed, the opening / closing valve 32 of the coagulation water drainage pipe 28 is closed, and the saturated steam of high temperature generated by heating to the electrothermal boiler 2 is supplied with a steam supply pipe. It is inserted into the pressure-resistant mixer 11 via (6, 27) to carbonize sawdust which is a raw material of wood vinegar.
