Zinc oxide rotary kiln burner: can achieve wireless temperature measurement function

1、 The working principle of zinc oxide rotary kiln is the entire process and principle of calcining zinc and treating zinc containing substances. Generally, zinc oxide rotary kilns are used to treat filter cakes containing zinc.

The zinc in the filter cake mainly exists in the form of zinc ferrite, oxides, and sulfates. At high temperatures in the zinc oxide rotary kiln, zinc ferrite reacts with solid carbon to reduce to metallic zinc. At the same time, the sulfates of zinc, lead, and cadmium are also reduced, and they are volatilized in the form of sulfides and gold ions. The metal that is reduced and evaporated from the solid phase is re oxidized under the action of the kiln atmosphere, mainly in the form of oxides.

2、 Characteristics of natural gas zinc oxide rotary kiln burner:

1. Multi channel or single channel design, the combustion tube material of the rotary kiln burner is stainless steel 310s, and the double-layer casing or combustion tube has a high-temperature resistant casting material structure, which can withstand high temperatures of 1100-1400 ℃. The flame length is long enough, and the flame length and shape can be automatically or manually adjusted. The high-precision UV probe monitors the flame combustion status in real-time. Once the flame is extinguished, the system will generate an audible and visual alarm and immediately cut off the gas.

2. Energy saving design. The structural design of the zinc oxide rotary kiln burner ensures accurate flow control of gas and air, accurate mixing ratio, and sufficient combustion, achieving the goal of energy conservation.

3. Design of automation control functions. The rotary kiln burner has functions such as ignition control, flameout alarm control, pressure control, and wireless temperature measurement control. According to the zinc oxide calcination process, automatic temperature control can be achieved. It can be connected to the central control room to achieve local and remote or mobile automatic control functions, and can monitor the working status of the rotary kiln burner in real-time, making it convenient for management.

4. Suitable for various fuels, it not only meets the requirements of environmental protection and low nitrogen emissions, but also achieves energy-saving goals. According to the selection of different fuels, they are classified into: natural gas zinc oxide rotary kiln burner, coke oven gas zinc oxide rotary kiln burner, blast furnace gas zinc oxide rotary kiln burner, converter gas zinc oxide rotary kiln burner, light hydrocarbon gas zinc oxide rotary kiln burner, and multi-channel coal powder burner.

5. Supporting dust removal, desulfurization, and denitrification equipment. According to environmental requirements, Zhongwei Environmental Protection provides SCR or SNCR denitrification processes, equipment selection, and construction.

6. Gas equipment and pipeline design and construction engineering.

The multi-channel coal powder burner can be further divided into: gas mixed combustion burner, oil gas mixed combustion burner, gas gas mixed combustion burner, etc

There are also diesel zinc oxide rotary kiln burners, heavy oil zinc oxide rotary kiln burners, and gas generator zinc oxide rotary kiln burners in foreign markets. For more information, please feel free to call (WeChat synchronization): 15713691937.
