The present invention relates to a waste plastic incinerator.

In general, since plastics have different combustion characteristics compared to other materials, there are technical problems when incineration of various wastes is mixed.Therefore, waste plastics are required to completely prevent combustion by re-burning combustion gases. It is required to be incinerated by a dedicated combustion apparatus.

In other words, the waste plastic has a high calorific value of 4,000-10,000Cal / kg, which is higher than other wastes, so that the furnace becomes hot at incineration. Therefore, the furnace temperature must be moderately suppressed. Therefore, rostol which is normally used during combustion may be closed, so special combustion technology is required, and therefore, a combustion device having a planar image is required, and the furnace wall is reduced by high heat to prevent damage to the furnace and occurrence of clean cars. In addition, the combustion air is sufficiently supplied into the furnace to be fully connected to the heated snow gas generated from the plastic on the burner to completely combust the combustion gas, and the combustion gas is re-burned by the air that enters the secondary gas outlet. It is necessary to prevent the generation of toxic gas by reburning by the air entered into the outlet at the second time. Although there are also plastic incinerators by the image combustion method, in this case, the gasification process and the combustion process are classified for complete combustion, and the combustion air is reduced as much as possible in the primary combustion chamber to pyrolyze and gasify the material by suppressive combustion. There is a device that completely burns combustion gas at a high temperature by diffusing and burning combustion air in a secondary combustion chamber, but the structure is complicated and complete combustion cannot be expected.

The present invention is intended to solve such problems, so that the combustion gas is sufficiently burned by supplying the combustion air in the gutter, the combustion furnace and the planar image, and the combustion gas is burned by the combustion air forcedly blown by the heat filter in the gas outlet. The gas is sucked and reburned to completely discharge the toxic gas and then discharged. Hereinafter, the gas will be described in detail with reference to the accompanying drawings.

The air inlet 14 is formed in the hopper 1 and the air inlet 4 is formed in the combustion chamber 2, and the planar image 3 is installed in the combustion chamber 2 to form a waste plastic combustion furnace. An anti-molding part is formed on the bottom surface of the combustion chamber 2 to fix the planar image 3 made of a refractory material, and an air supply pipe 5 communicating with the blower 8 is installed on the upper wall of the upper part of the planar image 3 so as to blow out the ejection hole 6 ) And a plurality of blow holes inclined in the blowing direction, and a plurality of blow holes (9) (9 ') are installed inclined outward in the combustion gas outlet (7). The heat filter 10 is provided with an air supply pipe (11) (11 ') in communication with the blower (15).

In the drawings, reference numeral 12 denotes a feed screw, 13 a barrier plate, and 16 waste plastic.

Referring to the effect of the present invention as follows.

The waste plastic 16 introduced into the hopper 1 pushes the blocking plate 13 by the air 12 and the force 12 forced to enter the air inlet 14 and falls into the combustion chamber 2 and falls to the air inlet 4. ) Is transported to the planar image (3) and melted into a viscous phase by high temperature, in contact with the combustion air entered in the), wherein a plurality of jets installed in the air supply pipe (5) in the upper peripheral wall of the planar image (3) The air is discharged from the ball 6 in the blowing direction and is completely burned, and the combustion gas is in the air supply pipes 11 and 11 'which are in communication with the blower 15 through the heat filter 10 installed in the gas outlet 7. ) And a plurality of blowout holes 9 and 9 'are laid in the air supply pipes 11 and 11' to be inclined outward, so that the combustion air forced into the blower 15 is blown out. 9 '), it absorbs the combustion gas in the combustion chamber (2) and burns it again to completely remove the toxic gas. It is discharged from the discharge (7).

In this way, the present invention adjusts the temperature in the furnace by forcibly supplying air to the planar image with the blower to completely burn the waste plastic, and the combustion gas is forcibly blown the combustion air to the heat filter installed at the gas outlet to produce the combustion gas. It is a very useful waste plastic incinerator for pollution prevention.
