Heat recovery incinerator using combustible waste as fuel

Abstract

Disclosed is a heat recovery incinerator using combustible waste as fuel. The heat recovery incinerator can protect the combustion plate and the second oxygen supply pipe installed in the combustion chamber so that they will not be damaged by the high temperature of the combustion chamber and the combustion exhaust gas. Thermal deformation and corrosion occur, thereby prolonging the life, and preventing the problem of reducing the performance of the internal structure due to the adhesion of foreign matter on the inner wall surface of the combustion chamber; and, performing complete combustion on the combustion exhaust gas generated during fuel combustion to make the exhaust gas The harmful substances contained are minimized, so that air pollution can be prevented. The heat recovery incinerator using combustible waste as fuel according to the present invention comprises: a combustion chamber surrounded by a wall made of a refractory and heat-resistant material layer; a combustion plate rotatably arranged on the side of the combustion chamber The lower part is for placing fuel for combustion. The above-mentioned combustion plate includes: a conical turntable made of alloy steel, a plurality of nozzles protruding from the upper surface of the turntable, and the plurality of nozzles inject combustion air in a certain direction; a rotating shaft is connected to the central lower part of the turntable, The turntable is supported in a rotatable manner; the air manifold is arranged at the lower part of the turntable to supply combustion air to the interior of the turntable; the heat-resistant and fire-resistant cover member covers the upper surface of the turntable to the protruding height of the nozzle to avoid Avoid protruding the nozzles to the side of the combustion chamber while exposing the upper surface of the turntable.

Description

technical field [0001] The invention relates to a heat recovery incinerator using combustible waste as energy fuel. Background technique [0002] Among wastes generated in various industrial fields and daily life, industrial materials and daily necessities made of various synthetic resins such as flammable polyethylene, plastics, and tires are the mainstream. Some of them are landfilled or incinerated after passing through the separation process. However, in the current situation where the green revolution is planned to be carried out in terms of policies in response to global warming, environmental pollution, and water quality improvement, if waste resources are landfilled, there may be serious Very big economic loss, and can produce the dual problem of polluting soil and contaminating groundwater. In addition, when the waste is incinerated, the combustion exhaust gas generated during the incineration of the waste will produce lethal soot and harmful gases, thereby polluti...

Problems solved by technology

[0007] However, in the incinerator of the above-mentioned structure, if figure 1 and figure 2 As shown, the turntable 111 and the nozzle 112 of the combustion plate 110 manufactured by welding or assembling with heat-resistant steel castings or stainless steel, and the second oxygen supply pipe 125 arranged in the center of the combustion chamber 100 along the vertical direction from the upper cover 103 The surface is directly exposed to the high temperature and combustion gas of the combustion chamber 100, so thermal deformation due to high temperature occurs in various parts made of metal, and the corrosion is accelerated by the combustion gas, resulting in a shortened life.

Therefore, the maintenance and replacement of the combustion plate 110 and the second oxygen supply pipe 125 bring about complicated operation and economical burden.

[0008] In addition, not only burnt ash is discharged in the residue processing passage 104, but also the unburned fuel remaining after combustion is discharged, so there is a need to separate the unburned fuel from the burnt ash and put it into the combustion chamber 100 again. low disadvantage

[0009] In addition, in the maintenance of the incinerator, for example, when removing foreign matter attached to the inner wall surface of the wall body 101, or maintaining or replacing the combustion plate 110, it is necessary to raise the upper cover 103 of the incinerator and carry out the process through the combustion chamber 100. Maintenance and replacement, but since the size of the upper cover 103 is too large and the space in the facility is narrow, it is difficult to separate, combine or move the upper cover 103, so maintenance and replacement operations not only require a lot of time, effort and cost
