Description

The present invention relates to a waste incinerator, and mainly installs a set number of electronic igniters around the furnace body, forms contact-type heating for the waste in the furnace, and puts it into a steaming state. . At the same time, a three-stage separation and filtration chimney is installed at the top of the furnace body, and a high-temperature electric heating device is installed at the top of the furnace to effectively remove moisture and harmful substances and incinerate waste. At the same time, the waste gas is burned to effectively prevent environmental pollutants and fire ash from scattering.

Generally, there are two types of waste disposal. One is a landfill method, and the other is a high-temperature incineration method. The former does not require a large equipment cost, but a large landfill site is required. Cheap. At the same time, serious inconveniences occur, and the high temperature incineration method is gradually replaced.

In the high-temperature incineration system, first, the construction of an incinerator is a necessary condition. Then, the incineration facility burns the waste into ash, which is collected and processed. This type of system is a good choice for waste disposal because it effectively reduces waste, does not pollute the water source, and requires much less land than landfills.

However, current high-temperature incinerators have the following problems.
First, when incinerating waste, oxygen is required and the flame becomes large, so a large amount of black smoke and waste gas is generated during combustion, and the toxic substances contained in the waste gas cannot be reduced effectively. Therefore, the air near the incinerator is contaminated.
Second, because the waste is incinerated at a high temperature, the environmental temperature of the entire incinerator and its surroundings rises, and there is a problem in the safety of workers.
Third, a large amount of energy is required to incinerate. For this reason, the incineration cost is increased, which has a great economic impact.
Fourth, private small incinerators tend to be inadvertently fired when incinerators are used because facilities are too simple and tend to neglect repairs.
The fifth is that the structure of this type of incinerator is complicated, which increases the cost of the entire facility.

As shown in FIGS. 1 to 3, the present invention mainly installs a furnace body 10 having a predetermined capacity, and the furnace body 1.
0 is circular or rectangular. Further, the furnace body 10 is provided with a heat insulating structure made of a chemical material in both the inner and outer layers so that the high temperature in the furnace is not transmitted to the outside of the furnace body 10. A double-layered waste inlet 20 is installed on the uppermost side surface of the furnace body 10, and two open / close plates 21 and 22 that open in different directions above and below are installed at the waste inlet 20. (The upper opening type is installed on the upper side and the inner opening type is installed on the lower side.) The pivoting side is automatically restored by the torsion springs 23 and 24 manufactured in advance. When the waste 1 is put into the furnace body 10 and combusted by the double partition, the combustion gas in the interior is prevented from leaking outside. In addition, a three-stage separation filtration chimney device 30 is installed on the uppermost side of the furnace body 10, a spherical steam separator 31 is installed on the lower stage, and a drain valve pipe 32 is installed on the outside thereof. The middle stage of this apparatus is a large-diameter filter 33, and a predetermined number of separation plates 34 are installed inside it, and its internal space forms a regular bypass, which has the effect of eliminating dust and water. Yeah. A drain valve pipe 35 is circumscribed on the outer side of the one side, and an electric heating device 36 is installed on the upper stage, and a bypass electric heating pipe 37 is installed on the inside. Due to the high temperature of the electric heating tube 37, toxic substances such as dioxin contained in the waste gas are effectively burned, and an umbrella-shaped chimney lid 38 is installed at the upper end of the outlet. In addition, on the side surface of the furnace body 10, an inlet hole valve 11 symmetric to a predetermined number of sets is installed if necessary, and each inlet hole valve 11 is provided with an opening / closing valve 12 and a forced inlet device 13 (which may be a small fan). The outside air is appropriately introduced into the furnace body 10 to increase the combustion efficiency. Further, an electronic igniter 14 is provided at a corresponding position inside each inlet valve 11.
These electronic igniters 14 are in contact with the waste 1 and contact-type heating is performed on the waste 1 to enhance the steaming effect, and the waste 1 is spontaneously ignited and steamed.
