Description

TECHNICAL FIELD The present invention relates to an underground incinerator for burning out dust and the like.

(Prior Art) Conventionally, this type of underground incinerator has a box-shaped furnace wall with a lid in which a hole is dug in the ground and the inner circumference is surrounded by a refractory wall. Although the main body of the incinerator with a roadway is buried and dust is incinerated by natural ventilation from the air intake of the lid, it has become widespread in recent years from the viewpoint of effective use of land and safety. However, this underground type incinerator burns relatively efficiently, although the detailed reason is unknown. The reason is probably that water and oxygen in the soil contribute to combustion.

(Problems to be Solved by the Invention) However, the efficiency of the conventional underground incinerator is lower than that of the method of forcibly blowing air. Therefore, in order to make up for this, an air intake port is provided in the side portion or air is blown in from the upper portion, but there is a problem that a preferable effect is not obtained.

The present invention has been made in view of such problems of the prior art, and its purpose is to make the air uniform by using an appropriate humidity underground and a ventilation pipe buried in the soil. It aims to provide an efficient underground incinerator that burns uniformly.

(Means for Solving the Problem) In order to achieve the above object, the underground incinerator of the present invention has a lid and an ash on one side of a box-shaped furnace wall with a lid whose inner circumference is surrounded by a heat-resistant wall. The outlet, the incinerator body having a flue port on the other side is buried underground, and a plurality of ventilation pipes having an appropriate number of orifices in the longitudinal direction are buried in the ground constituting the hearth part, and It is covered with green stone and heat-resistant aggregate is laid on top of it.

 Furthermore, the lid is provided with an air intake.

(Operation) In the underground incinerator configured as described above, when the air blown out from the blower exits the orifice of the ventilation pipe, it spreads in all directions due to the glystone, and further passes between the aggregates into the furnace. Sent in. At that time, the air can be uniformly sent out from the hearth while containing an appropriate amount of moisture in the soil. As a result, the combustion can be performed completely and efficiently.

(Example) Hereinafter, an example will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a lid 1a, and an inner periphery thereof is a box-shaped incinerator body surrounded by a refractory wall, which has an ash outlet 1b on one side and a flue port 1c on the other side. This incinerator body 1 is dug in the ground to be buried at an appropriate depth. The bottom of the incinerator body 1 is open and the hearth 2 is composed of the ground.
A plurality of ventilation tubes 3 having orifices 3a in the longitudinal direction
Are lined up and buried, the periphery thereof is covered with the glystone 4, and the heat-resistant aggregate 5 is further laid on it. A vacant chamber 6 is provided outside the ash outlet 1b to facilitate the work of taking out ash, and an opening / closing door 7 which is normally closed is attached to the ash outlet 1b, while a smoke outlet 1c is provided with smoke. The chimney 8 is connected via the road. Further, the lid 1a of the incinerator body 1 may be installed via a water cooling lid 9'made of steel plate so that heat of the furnace wall is not directly transmitted. Further, the lid 1a is provided with an adjustable air intake 9, which further improves combustion efficiency. 10 indicates a blower.

In the incinerator configured as described above, the air from the blower 10 is sent out into the furnace through the orifice 3a of the ventilation pipe 3, and the air from this orifice 3a is dispersed in each direction by the glystone 4, and the aggregate is used. It is uniformly leveled in the incinerator main body 1 by 5 and sent out. At this time, an appropriate amount of moisture in the soil and the air in the ventilation tube 3 can be leveled and discharged. As a result, the combustion is complete. Furthermore, the lid 1a
An air intake is provided in the to further improve combustion efficiency.

(Effects of the Invention) Since the present invention is configured as described above, it has the effects described below.

The ventilating pipe with an appropriate number of orifices in the longitudinal direction connected to the blower is buried in the hearth, and the top of the ventilating stone is covered with green stone, and the aggregate is laid on it. It will flow evenly. Moreover, the combustion is complete because it mixes from the soil with the appropriate humidity. Therefore, the amount of ash is smaller than in the conventional case. Furthermore, an air intake is provided on the lid to further improve combustion efficiency.
