Case introduction

In waste treatment, the most widely used hazardous waste treatment method in the world is high-temperature incineration treatment. The reason is that this technology has many advantages such as wide adaptability, thorough disinfection and sterilization, significant effect, and mature technology. It has been widely used internationally for many years. The main hazardous waste disposal technologies currently available in my country include: rotary kiln, pyrolysis incinerator, grate furnace and new plasma method. Today, Global Heavy Industries will introduce you to a customer's hazardous waste disposal project - hazardous waste rotary kiln project site~

Design parameters:

Capacity: 70(t/d)

Model: 3.15m*14m

Application: Solid and semi-solid waste materials that pollute the environment and cannot be discarded in mining, industry, production and construction. Including solid particles separated from wastewater and waste gas, and organic waste and inorganic waste

Case advantages

Advantages and characteristics:

1. It can incinerate solid waste, liquid, colloid and gas at the same time, and has strong adaptability to the incineration materials.

2. High-temperature materials are in contact with refractory materials, and it is convenient to replace the furnace lining at a low cost.

3. The transmission mechanism is simple, the transmission mechanism is in the kiln shell, and the equipment is easy to maintain.

4. It does not require high shape and moisture content of the incineration materials.

5. Good sealing measures and negative pressure in the furnace can ensure that harmful gases do not leak out.

6. The equipment has a high operating rate, and the annual operating rate can generally reach 90%, and it is easy to operate and maintain.

Production Process

Application and working principle of hazardous waste rotary kiln:

1. The hazardous waste is evenly mixed and moved along the tilt angle to the inclined end in a tumbling state through the overall rotation of the kiln body. In order to achieve complete incineration of hazardous waste, a secondary combustion chamber is generally provided. Its unique structure enables the process of hazardous waste drying, volatilization, ignition and burning to be completed in several heat transfer forms, and complete incineration is achieved in the secondary combustion chamber.

2. Most hazardous waste materials are heated by the gas generated during the fuel process and the heat transmitted by the kiln wall. After entering the incinerator, the hazardous waste first receives the heat radiation of the auxiliary burner flame and the high-temperature kiln wall to complete the process of heating, water evaporation and combustible precipitation.

Feedback

The hazardous waste incineration process uses highly automated equipment to reduce manual operation links, save cost investment, and maximize profit margins. Reasonable design of the production line can minimize production costs and allow users to recover costs within a relatively short period of time.
