Description

Oil heater {OIL HEATER}

The present invention relates to an oil heater, and more particularly, heats a plurality of pipes with a burner, places a blower on one side of the pipes in the longitudinal direction, and then continuously blows heated air inside the plurality of pipes through the blower to a room. It's about sending skills.

In general, in order to maintain the life of crops smoothly, an agricultural hot air fan or an agricultural hot air fan is used to maintain a constant internal temperature of a plastic greenhouse or greenhouse.

Such an agricultural hot air fan or hot air fan blows out the warm air or hot air that heated the outside air into the vinyl house or greenhouse to maintain a constant internal temperature of the vinyl house or greenhouse.

For example, Korean Registered Patent Registration No. 10-0952564 and Patent Registration No. 10-0800306 disclose "agricultural electric hot air blower" and "multi-stage hot air blower".

The 'agricultural electric hot air blower' includes an enclosure 20; The suction ports 30a and 40a disposed side by side on the lower side of the enclosure 20 and disposed in opposite directions to the inside at a predetermined distance G from the enclosure 20 and the discharge ports 30b and 40b upwards A pair of blowers (30, 40) each having; The pair of blowers (30, 40) of the outlet (30b, 40b) side of the inner heat box (50) and; A plurality of electric heating elements 60 arranged in a transverse row in the inner heat box 50 and installed in a staggered manner; It includes hot air discharge pipes 60 and 62 installed opposite to each other on the upper part of the inner heat box 50 and protruding out of the enclosure 20.

In addition, the 'multi-stage hot air blower' installs heat exchange plates 4 formed by welding and bonding a plurality of square pipes 4a and a front single tube 4b in a main body case 2 vertically spaced apart from each other in multiple stages, and heat exchanges in multiple stages. The square pipes 4a of the plate 4 are configured to communicate in a zigzag manner through the communication parts 16 to 16e on both sides of the body case 2, and the combustion chamber 8 in which the burner 10 is installed in the lowermost communication part 16a and the external gas discharge pipe 18 is connected to the uppermost communication part 16e, and the external air A forcibly supplied by the blower 20 installed in the body case 2 is supplied to the heat exchange plate 4 ) It is configured to be heat exchanged while passing through the heat exchange passage P between the main body case 2 and discharged as heated air through the air outlet 22 of the body case 2.

However, in order to supply high-voltage electricity to the electric heating element 60 in the conventional agricultural electric heater or hot air fan, a separate high-voltage electric facility inside the vinyl house or greenhouse and electrical facility construction for this were required. Therefore, there was a problem in that the initial investment cost was too high to equip the greenhouse or greenhouse with agricultural heating facilities.

In addition, since the conventional multi-stage hot air blower uses the burner 10, electrical facilities are not required, but separate pipes and ducts are required to supply hot air to the inner space of the greenhouse or greenhouse. That is, it is necessary to have a piping configuration in which vinyl pipes (P) are connected to the air outlets 22 so that hot air sent to the air outlets 22 is supplied to a certain space.

Therefore, since the conventional agricultural tube heater requires a separate duct pipe to be installed when the heater is installed in a greenhouse or a greenhouse, the structure is complicated and the cost increases.

Conventional Publication No. 10-2017-0135123 provides an agricultural tube heater.

Looking at its composition, it is as follows.

An agricultural tube heater according to the present invention is an agricultural tube heater for supplying warm air to an inner space of a greenhouse or a greenhouse, and includes a box-shaped case with open front and rear surfaces and forming an inner space of a certain size;

a combustor that burns a predetermined amount of oil and ejects flame and high-temperature combustion gas through a combustion pipe installed in the inner space of the case; heat radiation tubes installed in a zigzag pattern in the inner space of the case and dissipating heat to the outside while moving the high-temperature combustion gas generated in the combustion tube upward;

A blower installed on the open front of the case, sucking outside air into the case, bringing it into contact with the heat radiation pipe, and ejecting warm air, the temperature of which has risen by heat exchange with the heat radiation pipe, to the outside of the case. and;

a reflector installed on an open rear surface of the case to allow outside air sucked in by the blower to freely pass but to block heat emitted from the heat radiation pipe from being emitted to the outside of the case;

A gas discharge port installed at the rear end of the heat radiation tube to discharge combustion gas into the inner space of the case;

And the filter may be made of a metal mesh. The metal mesh installed at the rear end of the combustion pipe 27 is secondarily purified and discharges harmful substances such as nitrogen oxides (NOx) and volatile organic compounds (VOC) contained in the combustion gas, and also contains volatile organic compounds (VOC).

It can reduce odor (petroleum smell) and noise.

In this way, even if the combustion gas is purified through the filter, damage from the combustion gas cannot be avoided when used indoors, which is the user's home.

With this heating, the internal temperature of the plurality of pipes 140 is heated.

It exchanges heat with the discharged air of the blower 170.

Describing the heat exchange, when the blower 170 operates, the blower 170 sucks air in the atmosphere and discharges it to the first space 131 through the discharge port 171. At this time, the first space 131 It is dispersed in the plurality of pipes 140 and flows into one side 140a of the plurality of pipes 140 and moves in the longitudinal direction of the plurality of pipes to push the air inside the plurality of pipes 140 being heated or to exchange heat with the plurality of pipes.

Thereafter, the heated air passes through a plurality of pipes and moves into the room.

In conclusion, since many (a plurality of pipes) elliptical pipes 140h can be disposed in the narrow second space 132 in the width direction of the plurality of pipes 140, the effect described in the effect of the invention occurs.

Each of the plurality of pipes 140 is molded into an ellipse, and the vertical direction elongated in the ellipse is directed vertically to form the elliptical shape.

Looking at the following configuration:

The combustion gas outlet 160 formed in the second space 132 is connected to a heat exchanger 400 that exchanges heat with the latent heat discharged through the combustion gas outlet 160, and the heat exchanger 400 has a rectangular shape. Inside the formed heat exchanger body 410 and the heat exchanger body 410

first and second spaces 420 and 421 forming spaces in both directions of the heat exchanger body 410 by placing partition plates 411 and 412;

Arrange a plurality of metal pipes 430 between the first and second spaces 420 and 421

In the first space 420 of the first and second spaces 420 and 421, one side 430a of a plurality of metal pipes 430 is connected by passing through the diaphragm 411 at a predetermined distance from each other, and the The other side 430b of the plurality of metal pipes 430 is spaced apart from each other by passing through the partition wall 412 of the second space 421 and connected:

Connected to one side of the first space 420 to communicate with the combustion gas outlet 160, the latent heat contained in the combustion gas is introduced and dispersed to pass through the inside of the plurality of metal pipes 430 in the longitudinal direction to the second Pass through the space 421 and discharge into the atmosphere through the exhaust port 421a formed in the second space 421,

In the heat exchanger body 410 corresponding to the first and second spaces 420 and 421

By connecting the inlet 172 of the blower 170 to communicate

External air is introduced between the plurality of metal pipes 430 disposed between the first and second spaces 420 and 421 by the suction force of the blower 170, and after heat exchange with the plurality of metal pipes 430, the discharge port It is configured to discharge to the first space portion 131 via 171.

Looking at the following configuration:

When power is applied to the burner 150 and the blower 170, the burner 150 ignites oil and heats the plurality of pipes 140.

With this heating, the internal temperature of the plurality of pipes 140 is heated.

Heat is exchanged with the discharged air of the blower 170 and the flame generated in the burner 150 is a plurality of

Heat is exchanged with the pipe 430, but latent heat (heat remaining in the exhaust gas) remains in the exhaust gas generated from the flame of the burner.

The exhaust gas containing this latent heat is dispersed in the first space 420 through the combustion gas outlet 160 via the plurality of pipes 140 and then collected in the second space through the plurality of metal pipes 430. and is discharged through the exhaust port 421a formed in the second space.

In this process, a plurality of metal pipes 430 are heated by the latent heat of the exhaust gas, and the heated metal pipes 430 allow air in the atmosphere introduced by the suction force of the blower 170 to pass through the metal pipes 430. In the process of heat exchange, the plurality of pipes 140 pass through the first space 131 connected to the discharge port of the blower 170.

It has an energy utilization effect in that it warms the cold air in the atmosphere by passing the latent heat of the discarded exhaust gas through the heat exchanger.

The elliptical plurality of pipes 140 and the plurality of pipes 140 are spaced apart within a range of 5 mm to 10 mm and closely arranged in the width direction inside the body 110 of the boiler,
Each of the plurality of pipes 140 is molded into an elongated oval shape and arranged so that the elongated direction is directed vertically.
The diameter of the inner width direction of the plurality of pipes 140 is in the range of 4 mm to 7 mm, so that heat exchange is performed while water or wind from the blower moves in close contact with the inner wall of the plurality of pipes.

It was confirmed through experiments that when the diameter of the plurality of pipes 140 in the inner width direction is less than 4 mm, air resistance occurs and the blower wind does not move smoothly.

When the diameter of the plurality of pipes 140 in the inner width direction is 7 mm or more, air resistance does not occur, but it is confirmed that the air temperature in the air blower is lowered because heat exchange is not performed in the center of the air. .

In addition, by disposing the plurality of pipes 140 and the plurality of pipes 140 within a range of 5 mm to 10 mm, it is possible to accommodate a plurality of pipes 140 for heat exchange in a small space.

However, when the interval is within 5 mm, resistance is generated in the discharge flame of the burner and the burner does not burn smoothly,

When the interval is within 5 mm, a cleaning tool cannot be pushed between the plurality of pipes 140 and the plurality of pipes 140 .

In addition, when the distance between the plurality of pipes 140 and the plurality of pipes 140h is greater than the range of 5 mm to 10 mm, the flame of the burner 150 does not receive resistance, so that heat exchange is not performed smoothly and the combustion gas outlet 160 confirmed to move.

The body 110 is characterized by a configuration in which the outer case is doubled, and the wind of the blower is introduced into the double inner space (y) to push the heat of the inner space (y) to the outside and then discharge it to the room.

The reason for doing this is to use the heat transferred to the case of the body 110 as heating while reducing the cost of the insulation by avoiding a separate insulation device outside the body 110.

1. The plurality of pipes 140 are characterized in that the arrangement of the plurality of pipes 140 is arranged in a zigzag pattern so that the flame discharged from the burner 150 is distributed in a zigzag pattern inside the body 110.
