Abstract

PURPOSE:To enable a sufficient heating capability to be realized with a low fuel consumption without any red heated part by a method wherein a pilot burner arranged at a substantial central part of two opposed catalyst type main burners and a duct for guiding combustion gas to the surface of each of main burners are provided at an inner surface of a hood. CONSTITUTION:Two main burners 22 are attached in opposed truncated-chevron shaped form to an inner surface of a hood 21 through fittings 23 and 24, and a fixing unit 36 having a pilot burner 33, a spark plug 34 and a thermo-couple 35 is arranged between both main burners 22. Each of the main burners 22 is ignited with discharged gas fed out of the pilot burner 33 discharged from an exit opening 40 of a duct 38. Since a catalyst mat 46 starts an ignition at 150-250 deg.C, an ignition with a heat of the discharged gas is sufficiently enabled. Since the catalyst mat 46 has a high radiation rate of 60-70% irrespective of a low temperature, an amount of consumption of gas is reduced and a saving of energy can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a C gas broiler suitable for use mainly in pig pens in pig farms, poultry pipes in poultry farms, and the like.

"Prior Art" A large number of piglets are born in a pigpen at a pig farm, and these piglets are raised for a certain period of time in a farrowing cage or in a heating box while being heated. Conventionally, electric heaters have been used for this heat-retaining method, but this has the disadvantage of drying out the piglet's skin.

For this reason, recently, as shown in FIG. 9, a gas combustion device 15811 covered with bread or a hood 10 is suspended from the ceiling of a pigsty to heat the inside of the cage. In this gas combustor 11, when the combustion gas is blown out in the diametrical direction from the L hole 13 of the burner 12 and the heat is radiated downward through the curved mesh plate 14, the radiant heat from above and on the sides is also transferred to the hood 10.
It is reflected on the inner surface of the body and directed downward. 15
1 is a thermocouple, and 16 is a cock for switching the heating capacity, which is operated by a knob 17. The drying problem is solved because the gas produces moisture upon combustion.

[Problem to be Solved by the Invention] 1) However, in this type of gas combustor, the area is determined by the angle of the hood, so adjusting the area requires moving the entire gas combustor up and down. If you don't move (), you won't get 4T. Additionally, a gas burner is required for each cage in the pigpen;
Gas flow! Hfi becomes lonely like this, and Kos (~ also doesn't become a fool.

[1.1 of the invention] The present invention has been made in view of the above circumstances, and its purpose is to provide a combustor with sufficient heating capacity equivalent to that of a conventional combustor with less fuel consumption and without a red-hot part. You can demonstrate your skills and have a 1st channel A! - Our objective is to provide a simple gas catalytic combustor.

Means for Achieving the Objective 6 1 In order to achieve the above objective, the present invention provides a hood that opens in the F direction and can be hung to the side, and a hood that is attached to the inner surface of the hood in a V-shape. Gas catalytic combustion is carried out using two catalytic main burners, a foot burner installed approximately in the center of both main burners, and a duct that guides the combustion gas from the pipe burner to the surface of each main burner. It makes up the vessel.

[Saku Kawa 1] With this configuration, the surface of each main burner emits radiant heat without becoming red-hot, and each main burner is lit at the back of the chijimon with one pie.

[Example 1] Fig. 1 and Fig. 2 show a front view and a plan view of a gas catalytic combustor 20 to which the present invention is applied. The hood 21 is suspended from the ceiling (not shown) of the pigsty with its frontage facing downward.Both lower ends of the hood 21 are connected by a reinforcing iron 21a, and an exhaust hole 21b is formed in the upper surface.

Two main burners 22 are attached to the inner surface of the hood 21, facing each other in a V-shape, with metal pieces 4123 and 24 interposed therebetween. The metal fitting 23 has one end connected to the hood 2 as shown in FIG.
1 and connected to the rear end of the main burner 22 via a bin 25. The metal fitting 24 has an elongated hole 26, one end of which is fixed to the inner surface of the hood 21, and the main burnout 22 is fixed to a screw 27 and a washer 28 by J:.

Therefore, when the screw 27 is loosened, the main burner 22 moves by the stroke of the elongated hole 26! It can be rotated around the removal bin 25. Since the mounting angle of each main burner 22 can be adjusted individually, the center of the heating area can be changed as necessary.

A box 29 is provided on the top surface of the hood 21 (see Fig. 1).
A joint 30 for connecting a hose protrudes from the top surface of the box 29. A main hose (not shown) for gas supply is connected to this joint 30. Further, two gas pipes 31 branch from both sides of the box 29, and each gas pipe 31 is bent in the middle and connected to the C main burner 22.

A pulp 32 is provided at each bent portion of the gas pipe 31,
IMIll the gas flow paths individually using the operating lever 32a.
It is now possible to do so.

Behind both main burners 22, as shown in FIG. 4, a mounting bracket 36 is provided with a piston burner 33, a spark plug 34, and a thermocouple 35. This mounting bracket 36 is supported by an X-shaped clamp 37 in a hanging state from the rehood 21, and the upper end of the clamp 37 is fixed to the inside of the hood 21.

A duct 38 is connected to the mounting bracket 36 by screws 39, and two outlets 40 of the duct 38 are connected to each main burner 22.
facing the surface of The duct 38 has an inverted U-shape or a U-shape formed by folding a flat plate in half, and has an outlet 40 cut out so as to be parallel to the main burner 22 .

On the other hand, the pilot burner 33, the spark plug 34, and the thermocouple 35 pass through the mounting bracket 36 into the duct 38.
It's going inside. Further, a gas pipe 33a (FIG. 1) for gas supply is connected to the rear end of the pilot burner 33, and the other end of the gas pipe 33a reaches a box 29 on the top surface of the hood. Therefore, when gas is supplied to the pilot burner 33 and the spark plug 34 is ignited, the pilot burner 33 will burn within the duct 38.

Although not shown, a valve is provided in the box 29, and ignition and gas supply to the gas pipe 31 and pilot burner 33 are performed by operating a knob 41.

The main burner 22 is surrounded by a casing 42, as shown in FIG. Inside the casing 42, a current plate 43, a heat insulating layer 4/1.45, and a catalyst mat 46 are arranged in a stacked state, and the surface of the catalyst mat 46 is made of gold II/
17 is protected.

A large number of small holes 48 are bored in the current plate 43 at approximately equal intervals C so that the gas introduced into the casing 42 from the gas pipe 31 passes through each small hole 48 equally. Furthermore, a plurality of small holes 31a are formed along the axial direction on the upper surface of the gas pipe 31 inserted into the casing 42, so that the supplied gas is diffused inside the casing 42.

The catalyst mat 46 is formed using a catalyst such as platinum or palladium, and burns the supplied gas without generating flame, and combustion heat is directly radiated outside in the form of far infrared rays from the catalyst. Heat retention layer 44. /15 are formed of glass wool and ceramic fiber, respectively, and prevent the combustion heat of the catalyst mat 46 from escaping to the rear of the main burner 22 (upward in FIG. 5).

The catalyst mat 46 and the wire mesh 47 are fixed around the casing 42 by a sash frame 49.

Each main burner 22 is ignited using the IJI gas from the burners 33 discharged from the outlet 40 of the duct 38. The catalyst mat 46 is 150 to 250
Since combustion starts at 'C, the heat of this wandering gas is sufficient to ignite.

The operation order of the gas catalytic combustor 20 configured as described above is as follows.

First, the gas combustor 20 is hung for each cage using a chain shade at a position of 60 to 80[alpha] from the floor of the pigsty. Next, the piglet enters the heating area J: Sea urchin each main burner 2
For installation 2, adjust the angle.

Gas catalytic combustion:! 1120, press the knob 41 of the box 29 (it rotates by a predetermined amount). This causes the gas supply and ignition of the pilot burner 33/\ to be carried out simultaneously, and the gas is supplied from the outlet 40 of the duct 38. Exhaust gas is supplied to each main burner 22. At this time, gas also flows into the gas pipes 31 on both sides from the box 29, but the gas is blocked by each valve 32 midway.

Next, turn the lever 32a of the pulp 32 to supply the gas in the gas pipe 31 to the main burner 22.

These gases flow into the inside of the casing 42 from the small holes 31a of the gas pipe 31 as shown in FIG. Heat retention layer 44.45
It passes through the gap and reaches catalytic pine]・46.

Since the part of the catalyst mat 46 facing the outlet 40 of the duct 36 is heated by the exhaust gas from the pilot burner 33, the gas starts catalytic combustion centering on this part, and gradually the entire surface of the burner is burned. I will do it. The exhaust gas of the main burner 22 is passed through the hole 21b of the hood 21 (
Figure 1) is discharged from □.

Since the surface temperature of the catalyst mat 46 is about 400°C and does not become red hot, it is highly safe and the piglets are not afraid of flames. In addition, catalytic combustion has low GO/002 and produces almost no NOx, resulting in no pollution. Furthermore, the radiation efficiency of the catalyst mat 46 is as high as 60 to 70% for 1 fl of low heat generation in spite of the low temperature, so the gas consumption 1 d is reduced, leading to energy saving. Of course, since the main burner 22 is a gas combustion type, a certain amount of moisture is generated and the piglet's skin does not become dry. If the temperature inside the pigsty is not so low, one of the main burners 22 is stopped by operating the lever 32a.

Although not shown, inside the box 29 there is a safety 5
lit is installed, and when the mocouple 35 detects that the pilot burner 33 is turned off, the gas supply from the main hose is turned off by 1 degree. With this configuration, even if there are two main burners 22, it is possible to detect one thermocouple 35r' going out.

6 to 8 show other angle adjustment mechanisms for the main burner 22. In this embodiment, the metal fitting 24 is fixed to the side surface of the main burner 22 on one side, and one end of the bottle 50 is attached to the metal fitting 24 in a continuous manner. The other end of the bottle 50 protrudes through the hood 21 through v1, and its 7 lunges 51
is in contact with the upper surface of the hood 21.

A plurality of protrusions 52 protrude in the radial direction from the inside portion 1a1 of the bottle 50, as shown in enlarged form in FIGS. 7 and 8. A coil spring 53 is interposed between the hood 21 and the mounting bracket 249. On the other hand, the hood 21 is integrally formed with the sleeves 1 to 54 and the hole 55, and the size of the sleeves 1 to 54 is is larger than the protrusion 52 of the bottle 50 by \1.

Therefore, if the bottle 50 is turned 90°E1 (Fig. 8),
The bin 50 can now be moved in the axial direction, and the main burner 22 is at an angle 'JA?' as shown in FIG. It will be ll+. Once the set angle is determined, when the bin 50 is rotated 90 degrees again, the protrusion 52 is engaged with the top surface of the hood and the main burner 22 is fixed. Since the biasing force of the coil spring 53 is acting, the bottle 50 and the main par 22 do not shake.

In the above embodiment, the reverse (3-shaped or U-shaped duct 38) is used, but a Y-shaped branch duct can also be used.

[Effects of the Invention] As described above in detail, the gas catalytic combustor of the present invention has a hood that opens downward and can be suspended from the ceiling, and GJ that is mounted oppositely in a V-shape on the inner surface of the hood. It consists of two catalytic main burners, a pilot burner numbered in the center of both main burners, and a duct that guides the combustion gas from the pilot burners to the surface of each main burner. It can demonstrate sufficient heating ability without any parts, and can also heat two main burners with one burner, reducing fuel consumption and saving energy.
You can obtain effects that lead to.
