Abstract

(57) [Summary] [Objective] Use a general-purpose burner such as a stove used for home or business use or a Bunsen burner for a bath to make an inexpensive CO ₂ generator for plant cultivation. . [Composition] The burner 10 burns in the inner cylinder 4, and the combustion exhaust gas is horizontally discharged by the baffle plate 2 provided above the inner cylinder 4. Air is taken in from the supply cylinder 1, mixed with combustion exhaust gas and cooled, but the air flow created by the baffle stabilizes the combustion air of the burner 10.
It plays a role of helping the discharge of combustion exhaust gas and mixing with air, and becomes low-temperature combustion exhaust gas which is transported by the fan 12 and can be distributed to various places for use.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

The present invention relates to a CO ₂ generation device used in a greenhouse for plant cultivation.

[0002]

[Prior art]

Conventionally a method for supplying CO ₂ to house for plant cultivation, and by cylinder filled with pure C O _2, and those utilizing flue gas, which need use the two ways.

A method of using combustion exhaust gas is to install a burner in a greenhouse for plant cultivation, burn fuel such as kerosene or LP gas with the burner, and release the combustion exhaust gas into the house for plant cultivation. Then, it diffuses and uses CO ₂ in the combustion exhaust gas. Household stoves and gun-type burners are used as burners.

[0004]

[Problems to be solved by the device]

The CO ₂ supply device that uses combustion exhaust gas that has been used in the past is a system that burns fuel with a burner and dissipates the immediate combustion exhaust gas, so heating provided at another location of the plant cultivation house. It is necessary to stir the air in the room using a large fan for the machine to make its concentration uniform, and it is not possible to spray it locally in the room or supply it to a remote house with one device. There was a defect such as being. These drawbacks can be solved by directly connecting the flue gas to a pipe and providing a device that can discharge the flue gas at an optimum place. However, the flue gas is at a high temperature, and the flue gas is completely burned to produce a clean gas. Therefore, in a general-purpose burner other than the burner for the purpose of burning in the tube, if the combustion exhaust gas is directly connected to the tube, unburned components are generated and the combustibility deteriorates. The present invention uses a burner (LP gas Bunsen burner, etc.) used in a semi-closed combustor, which has a high versatility used in baths, etc. The goal is to increase the utilization of CO ₂ generators with high efficiency.

[0005]

[Means for Solving the Problems]

 The combustion exhaust gas is mixed with air at room temperature to be cooled, and the baffle plate 2 for reducing the influence of the flow of the mixing air is provided, and the inner cylinder 4 having a heat retaining property like a combustion chamber is provided. This is a method in which a clean combustion exhaust gas is produced at a low temperature by assisting the combustion of the burner 10 and is introduced into the fan 12.

[0006]

[Work]

 Fuel such as LP gas is burned by the burner 10 in the lower part of the inner cylinder 4 to become combustion exhaust gas and rises in the inner cylinder 4, is bent horizontally by the baffle plate 2 and flows to the upper part of the outer cylinder 5. At this portion, the air is mixed with the air sucked from the supply cylinder 1 by the fan 12, is pressurized through the lower portion of the outer cylinder 5, and is supplied to a predetermined place by the pipe connected to the fan outlet 13.

[0007]

【Example】

 When LP gas was used, a large commercial round Bunsen stove and a bath reboil burner were used as the burner 10, and good combustion could be continued in any case.

[0008]

[Effect of device]

The baffle plate 2 allows the combustion gas to be smoothly discharged by the effect of the jet pump of the air from the supply cylinder, and the flame holding and heat retaining effect of the inner cylinder 4 improves the combustibility. Since only the inner cylinder 4 is hot, it is easy to take measures against accidents such as burns due to contact. If the fan 12 breaks down, the cylinder 1 can be used as a natural draft instead of the chimney. The above is the technical effect, but since a general-purpose burner (for stove and bath) can be used, it becomes an economically efficient device, so its application range for agricultural use (CO ₂ cultivation) is wide. Is to be. It is convenient because it can be applied as a hot air generator.
