AI Technical Summary

Technical Problem

When the existing incineration method treats combustible solid waste, it is difficult to maintain the reducing atmosphere inside the incineration system, and the reducing agent spraying lacks a high degree of consistency with the material delivery timing, resulting in increased environmental pollution and energy consumption.

Method used

A rotary combustible waste treatment device is designed to achieve precise control of the material delivery timing and the spraying timing of the reducing agent through the solid panel, mesh panel and spraying ventilation mechanism in the feeding system, ensuring that the reducing agent and the delivery rules of the material are highly matched.

Benefits of technology

Effectively maintain the reducing atmosphere inside the incineration system, avoid exceeding the neutralization level of the reducing agent in the oven due to excessive material combustion, and reduce environmental pollution and energy consumption.

Abstract

The invention discloses a rotary combustible waste treatment device and treatment method, and belongs to the technical field of combustible waste treatment. The device comprises a feeding system and an incineration system connected with the feeding system. A solid panel, a net panel and a spraying ventilation mechanism in the feeding system are arranged in the feeding unit, the solid panel and the net panel are arranged up and down, and the spraying ventilation mechanism is arranged between the solid panel and the net panel; the solid panel, the net panel and the spraying ventilation mechanism are all connected with the control unit, and the control unit is used for controlling opening and closing of the solid panel, the net panel and the spraying ventilation mechanism. A combustor in the incineration system is arranged on an outer kiln body of the rotary kiln and connected with an inner kiln barrel of the rotary kiln, the inner kiln barrel of the rotary kiln is arranged in the outer kiln body of the rotary kiln, an inlet section of the inner kiln barrel of the rotary kiln is connected with the tail portion of the feeding system, and a waste discharging opening of the inner kiln barrel is formed in an outlet section of the inner kiln barrel of the rotary kiln. And the inner kiln cylinder waste discharge opening is communicated with a waste gas discharge pipeline and a kiln body waste discharge channel. According to the treatment device, the spraying of the reducing agent can be highly matched with the material feeding rule, so that the reducing atmosphere in the incineration system is maintained, the situation that the neutralizing level of the reducing agent in the incinerator is exceeded due to excessive material combustion is avoided, and toxic gas pollutants generated during combustible solid waste incineration can be purified.
