[0010] Preferably, the smoldering box is a small and lightweight smoldering box with a relatively low height.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention discloses a multi-layered modular smoldering equipment processing system. A heating and ventilation chassis and a smoke collecting hood are provided. A sealing ring is provided on the heating and ventilation chassis. Driven by a four-linkage screw hoist, the smoke collecting hood presses down a smoldering box, and the smoldering box presses down the heating and ventilation chassis, so that a closed space is formed among the smoke collecting hood, the smoldering box and the heating and ventilation chassis, so that the material in the smoldering box is easy to ignite and burn.

[0013] The present invention is provided with a stationary combustion module, which includes a plurality of air intake chassis, on which multiple layers of smoldering boxes are stacked. The multiple layers of smoldering boxes burn simultaneously to obtain several times or even dozens of times the smoldering combustion area, which greatly improves the smoldering treatment efficiency; at the same time, the small smoldering box has a small volume, a light weight, and a small amount of material loaded, so the structural strength requirement is low, steel is saved, and the processing requirement is not high, thereby greatly reducing the comprehensive cost of the equipment.

The air intake fan, the exhaust gas extraction fan and the electric heating tube are powered by the power distribution control system. The exhaust gas extraction fan collects the exhaust gas generated during the ignition and combustion of the materials in the smoldering box through the extraction pipeline and transports it to the exhaust gas treatment equipment. The exhaust gas treatment equipment transports the exhaust gas from the lower layer to the upper high-temperature combustion area, so that most of the exhaust gas is destroyed by high temperature, thereby realizing the exhaust gas treatment function.

[0015] The present invention is provided with a clustered thermocouple on the top of the smoke collecting hood of the multi-layered static smoldering module. The clustered thermocouple can monitor the reaction temperature of the material in the smoldering box. When the reaction temperature in the top smoldering box is too high, the clustered thermocouple will feed back a signal to the power distribution control system. The power distribution control system adjusts the speed of the intake fan by adjusting the power of the intake fan, and then adjusts the ventilation volume in the smoldering box in the static combustion module, so as to control the reaction speed of the material in the smoldering box within a reasonable range. When the reaction is completed, the material temperature drops to the set value, and a prompt will be given to unload the material.

[0016] The invention is provided with a special forklift, which can perform loading, unloading and transportation work in the smoldering box field, and can also perform stacking and destacking operations on the smoldering boxes.

[0017] The present invention is provided with an industrial tent, which can avoid the exhaust leakage of the ignited smoldering box during the transportation process and can also avoid the influence of rainy days on the transportation process of the smoldering box.
