The waste liquid to be incinerated flows into the waste liquid spray pipe 44 through the waste liquid pipe 46, the compressed air sprayed from the atomization pipe 47 atomizes the waste liquid in the waste liquid spray pipe 44, and the atomized waste liquid is sprayed into the combustion chamber 24 from one end of the waste liquid spray pipe 44 for incineration.

The first path of air distribution enters the first air channel 311 from the combustion-supporting air pipe 33, passes through the swirler 45 and is sprayed out in front of the fuel gas nozzle 35, and part of the first path of air distribution is combustion-supporting of fuel gas; the other part of the first air distribution channel moves along the sleeve 41 and rapidly heats up in the moving process, provides combustion support for the combustion of the waste liquid sprayed by the waste liquid spray pipe 44, and has the functions of auxiliary atomization and rectification of the waste liquid. The second air distribution channel enters the second air channel 312 through the combustion-supporting air pipe 33, firstly passes through the vent holes 361 of the air-equalizing plate 36, so that the wind power becomes uniform, then is ejected out of the gas nozzle 35 through the air distribution holes 371 of the air distribution channel 37, and can be rapidly mixed with the gas, so that the combustion efficiency can be improved, and the stability of flame combustion is improved. The temperature-raising cavity 61 ensures that the temperature in the cavity is higher by utilizing the combustion of fuel gas, and the area is rich in oxygen, so that the atomized waste liquid can be quickly ignited and quickly combusted, thereby improving the combustion speed and the temperature-raising speed of the waste liquid and being beneficial to the quick oxidation of harmful substances.

When a plurality of waste gases need to be incinerated, a plurality of waste gases with the same property are respectively communicated with the plurality of waste gas pipes 25 of the same waste gas channel 221, then the rest of waste gases with different properties are respectively communicated with the waste gas pipes of different waste gas channels 221, and the redundant waste gas pipes 25 on the plurality of waste gas channels 221 are sealed. The waste gas can then enter the combustion chamber 24 through the air holes 231 of the pouring refractory layer 23, and the arrangement enables the high-efficiency combustor to burn a plurality of waste gases with different properties at the same time. The amount of oxygen required for combustion in the weak oxygen combustion chamber 62 is insufficient, and the combustion intensity of the flame is low, so that the conditions for generating nitrogen oxides are lacking, and the generation of nitrogen oxides, especially the combustion of nitrogen-containing organic matter, can be suppressed. The aerobic incineration chamber 63 contains less combustion-supporting air, which is beneficial to the incineration of organic components in waste gas and waste liquid.

The special design mode of the three combustion sub-cavities can enable the efficient combustor to accelerate the combustion speed, the temperature rise speed and the combustion temperature of the waste gas and the waste liquid to be high, can burn the chlorine-fluorine-containing organic waste liquid and the waste gas, has high burning removal rate and inhibits the generation of dioxin. Meanwhile, the oxygen content in the weak oxygen incineration chamber 62 is easy to reduce, and the generation of nitrogen oxides is inhibited.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
