Description

  The present invention relates to an improvement of a small self-burning incinerator that burns only by self-combustion of an incinerated object without using a combustion air blower or a combustion burner when incinerating general dust and waste.

2. Description of the Related Art Conventionally, an incinerator that combusts only by self-combustion of an incinerated object after igniting the incinerated object is known, and disclosed in, for example, Patent Document 1 and Patent Document 2. According to these known means, the incinerated material is put into the furnace, ignited by the burner, burned while colliding and mixing flue gas and preheated air, and when the temperature reaches a predetermined temperature, combustion in the burner is stopped. In addition, the exhaust gas and the preheated air are collided and mixed, and the high temperature atmosphere in the furnace is self-combusted by the interaction caused by the combustion of the incinerator.

  However, in the structure of the combustion furnace of the above-mentioned Patent Document 1, it is difficult to completely burn the incinerator by only self-combustion at all times. For this purpose, a fuel oil addition section is provided in the combustion chamber flue section of the combustion furnace. When black smoke is generated from the chimney tip due to incomplete combustion, fuel oil is added to the smoke exhaust section to promote combustion. Therefore, the space for installing the fuel oil tank and the installation of the oil supply pipeline are required, and the entire apparatus becomes complicated and large, and the opening and closing operation of the oil supply valve is troublesome. There are problems such as causing secondary pollution such as CO2.

  Further, according to the means of Patent Document 2, a preheated air pipe that extends from the outside of the furnace through the hearth and into the chimney is installed so that preheated external air is introduced into the chimney and the fire smoke is mixed and burned. Although it is smokeless and non-brominated, the structure is complicated to install preheated air piping, and it is not possible to expect complete combustion of fire smoke simply by introducing preheated external air into the chimney. Complete smoke-free and bromide-free cannot be achieved. In addition, in conventional combustion furnaces including the above-mentioned known combustion furnaces, high-temperature smoke stays in the chimney for as long as possible to expect recombustion of smoke and to discharge harmful smoke and odors at high places However, the chimney is long and, therefore, there are problems such as restrictions on the installation location.

  Therefore, the present invention does not use a blower or a combustion burner for supplying combustion air, and completely burns only the self-combustion of the incinerated material, and the smoke generated by the combustion of the incinerated material is heated in the flue By reburning, the smoke is eliminated, and the odor is removed by the action of the catalyst to make it completely smoke-free and bromide-free, and the chimney length is reduced by adding a unique device to the chimney leading to the chimney. The main purpose is to provide a novel self-combustion type incinerator that can be shortened, and thereby makes the entire incinerator compact.

  In order to achieve the above object, the present invention takes the following technical means. That is, in the incinerator according to the present invention, the combustion chamber 2 is provided inside, and the inlet 3 for introducing the incinerator into the combustion chamber 2 and the inlet 4 for naturally aspirating the combustion chamber.

Another feature is that the upper end of the flue 6a communicates with the upper portion of the combustion chamber 2, and the upper end of the other flue 6b communicates with the chimney 5. The flue that is divided into two by the partition wall 7 in this manner substantially serves as a chimney through which smoke passes, so that the chimney 5 can be shortened by the length of the flue. Further, since a part of the flue is formed adjacent to the wall surface 2a of the combustion chamber 2, the high temperature atmosphere can be sustained for a long time by receiving the heat of the combustion chamber while passing through the flue, and the smoke combustion effect is promoted. In addition, the recombustion efficiency at the heater portion can be increased.

The additional charging port 11 includes a cylindrical frame 13 having an incinerated material storage chamber 12 therein, a first opening / closing lid 14 for additionally supplying the incinerated material into the incinerated material storage chamber 12, It comprises a second opening / closing lid 15 formed between the incineration chamber 12 and the incineration chamber 2 and is formed so that the opening / closing lids 14 and 15 can be individually opened and closed. As a result, smoke and high heat in the furnace are discharged into the atmosphere from the additional inlet 11 when the incinerator is additionally charged during the combustion of the incinerator, and the atmosphere is polluted or the health of workers is impaired. Can be prevented in advance.

  It is preferable that the intake port 4 described above has a structure capable of arbitrarily adjusting the amount of inflow air. The intake port 4 is preferably formed so as to be used as a window for visually checking the combustion state in the furnace, but a viewing window may be provided separately.

  In the incinerator of the present invention, the incinerator is completely burned only by self-combustion, and the smoke generated by the combustion of the incinerator is reburned with a heater in the chimney, and the odor is removed by the action of the catalyst. Complete smoke-free and bromide-free can be achieved. In addition, a flue that guides smoke from the combustion chamber to the chimney is divided into two with a vertical partition wall leaving a passage in the lower part by a vertical partition wall, and one of the divided By adopting a structure in which the upper end of the flue communicates with the upper part of the combustion chamber and the upper end of the other flue communicates with the chimney, this flue substantially serves as a chimney through which smoke passes. This makes it possible to shorten the chimney by the length of the flue, and because part of the flue is formed along the wall of the combustion chamber, it receives the heat of the combustion chamber while passing through the flue A high-temperature atmosphere can be maintained for a long time, the combustion effect of smoke can be promoted, and the recombustion efficiency at the heater part can be increased. Further, since the incinerator of the present invention is compact and clean, it has various excellent effects such that it can be widely used for general household use or as a simple incinerator in an office or factory.
