the cross sections of the reaction bodies 12 in the middle straight section are the same and are symmetrical left and right;

a flame holder 121 is disposed within the reaction body 12. The flame holder 121 is a turbine-type structure as shown in fig. 3, wherein the middle part is a solid similar to an ellipse, and the periphery of the solid is a turbine-type channel. The flame holder 121 is made of a high heat-storing, wear-resistant, high-temperature-resistant material. The ellipse-like solid structure in the middle of the flame stabilizer 121 can make the waste liquid droplets of the initial reactant 12 evaporate and crack rapidly and reach the ignition point; the turbine type channels around the flame stabilizer 121 enable reactants and primary air input through the primary air pipe 111 to be better mixed, reaction rate is improved, internal circulation beneficial to waste liquid reaction is filled with the whole lower reaction body, and utilization rate of the lower reaction body is improved.

In the reaction body 12, along the reaction flow direction of the organic waste liquid, a plurality of stages of diversion arches 123 are arranged from bottom to top in a staggered manner, and the diversion arches 123 can be integrally poured by high-temperature-resistant and high-strength wear-resistant pouring materials and are integrated with the inner wall surface of the cavity of the waste liquid reaction device 1. As shown in fig. 1, three stages of flow guiding arches, i.e., a first stage flow guiding arch, a second stage flow guiding arch, and a third stage flow guiding arch, are arranged in the reaction body 12; the structure of the diversion arch 123 is shown in fig. 4, the included angle b between the lower surface of the diversion arch and the horizontal plane satisfies the following conditions: 15 DEG < b < 65 DEG; the height of a vertical section surface of the right side of the reaction body cavity is A, the free end of the left side of the reaction body cavity is in a circular arc shape with the radius of R1, and the R1 satisfies the following conditions: r1 is (0.3-0.8) A.

The height H1 ensures that enough space is reserved below the flow guide arch on one hand, and the space requirement required by waste liquid reaction is met; on the other hand, the diversion arch can be ensured to have the functions of heat storage and heat supply for the reaction. The height is too low, the space is too small, and the reaction process of waste liquid is blocked; the height is too high, the space is too large, a temperature field and a flow field required by the reaction cannot be formed, and meanwhile, the function of the flow guide arch is reduced or even does not work.

L1 is mainly used to ensure the waste liquid reaction position below the diversion arch and to ensure the reactant flowing through the diversion arch has proper speed.

The end part of the left inclined plane is limited to be positioned on the right side of the central line of the reaction body, so that the flow speed of tail gas during turning can be adjusted, and the flow speed is controlled to separate larger and heavier dust particles in the tail gas. The distance between the end of the left inclined surface and the center line of the reaction body 12 is further limited to L3, L3 ≧ 1/4D, where D is the diameter of the reaction body 12. By limiting the size of L3, the flow rate of the diverted exhaust gas can be adjusted, and controlling the flow rate allows larger, heavier dust particles in the exhaust gas to be separated.
