Problems solved by technology
[0007] In order to overcome the existing deficiencies such as high fuel cost for waste incineration, complex layout of peripheral pipelines, and short service life of kiln refractory materials, the low calorific value gas incineration device for waste proposed by the present invention, on the one hand, replaces high-cost fuel and simplifies the air duct The arrangement of air duct valves and accessories can be reduced to reduce investment and operating costs. On the other hand, the heat intensity of kiln head combustion can be reduced, the flow field can be optimized, and the maintenance and replacement cycle of refractory materials can be extended.

The invention relates to the technical field of waste incineration equipment, in particular to a device for incinerating waste with low calorific value gas, which includes a rotary kiln and a secondary combustion chamber connected to the kiln tail. A sleeve-structured low calorific value gas burner is provided with a waste feeding port around the burner. The low calorific value gas burner is sequentially provided with an ignition device, an inner air layer, a low calorific value gas layer, a flame holding air layer and an outer air layer from the inside to the outside. The low calorific value gas burner is respectively connected with a gas pipeline and an air pipeline, and a controller is arranged in the pipeline. The incineration device of the present application mainly has the following advantages. The main fuel is gas with low calorific value, and the operating cost is low; the combustion flame is relatively short, and the thermal impact on the refractory material at the kiln head is small, which can prolong the service life of the device; the adjustment ratio of the device is High, it can operate at a load as low as 25%, adapting to the fluctuating working conditions of the rotary kiln; the device adopts diffusion combustion, which is conducive to reducing the combustion temperature and reducing the emission of NOx and other pollutants.
Description
A device for burning waste with low calorific value gas technical field The present invention relates to the incineration equipment technical field of waste, be specifically related to a kind of low calorific value gas incineration waste device. Background technique [0002] With the acceleration of my country's urbanization process and the improvement of people's living standards, the population absorbed by the city is more and more. The urban waste in many cities is close to the city's disposal limit, and various chemical solids are produced in the process of chemical industry and other industries. It faces the same problem of disposal as liquid waste. The incineration of waste and other wastes has been proved to be feasible Option to use rotary kiln to incinerate waste and industrial waste, and use the secondary combustion chamber to further burn the exhaust gas and high temperature removal of the rotary kiln Dioxin is a commonly used process route. The waste r...
