Description

Technical Field

[0001] The utility model relates to the technical field of incinerator outlets, in particular to an incinerator outlet material blocking device. Background Art

[0002] As a primary incineration equipment for solid waste, the rotary kiln is the main device for achieving waste reduction and harmless treatment. The waste undergoes three stages of preheating, combustion and burnout in the rotary kiln, which decomposes the waste.

[0003] The main components of the rotary kiln include the kiln body, heat-resistant steel plates are arranged circumferentially inside the kiln tail, sealing devices are arranged at the kiln head and the kiln tail, the rotary kiln frequency conversion transmission device, gear transmission device, the kiln head is provided with a feed inlet, temperature measuring points, burner ports, observation ports, etc. Under normal circumstances, the residence time of solid waste in the rotary kiln is more than 1 hour, and it meets the requirements of the "Hazardous Waste Incineration Pollution Control Standard GB 18484-2020". The thermal loss rate of the material must be less than 5%, so the material is required to stay in the combustion zone for a longer time.

[0004] In general, if it is necessary to further extend the residence time of materials in the kiln, the following three methods are generally used: First, during the design, the flow angle of the low rotary kiln is usually less than 3% overall, that is, the falling angle of the solid waste in the combustion zone is about less than 3%; second, during the design, multiple tangential winds are set to effectively extend the residence time of the flue gas in the furnace; third, during operation, the unit speed of the incinerator can be reduced, which is generally achieved by adjusting the frequency of the transmission motor, that is, reducing the frequency to 5HZ (maximum 50HZ).

[0005] In the prior art, during actual operation, when a batch of solid waste has a high moisture content and is too viscous, the angle of the rotary kiln cannot be adjusted, so the residence time cannot be continuously adjusted; the operating frequency of the rotary kiln drive motor is operated at a low frequency for a long time, which can easily reduce the service life of the motor; excessive wind speed can easily increase operating energy consumption; therefore, its thermal reduction rate often cannot meet the requirements, and the subsequent landfill costs of enterprises will also increase accordingly. In addition, when exhaust gas is discharged, how to increase the exhaust gas filtration effect under the same size is also an urgent problem to be solved. Utility Model Content
