This utility model relates to the field of biomass baking technology, specifically disclosing a biomass baking device, including a base plate and a baking tank. A flat plate is fixedly connected to the outer wall of the baking tank above the base plate. A high-efficiency exhaust gas treatment mechanism is provided above the base plate. The high-efficiency exhaust gas treatment mechanism includes a heat-conducting bend connected to the upper end of the baking tank. A condenser sleeve is provided on the outer wall of the heat-conducting bend. The lower and upper sides of the outer wall of the condenser sleeve are respectively connected to an inlet pipe and an outlet pipe. After cooling, the exhaust gas enters the filter box through a horizontal pipe to complete gas-solid separation. Then, it is pressurized by a gas pump and injected into an acid gas treatment box. The acid gas is neutralized by NaOH solution, thereby achieving the effect of deacidification of the exhaust gas. The exhaust gas is heated to the catalytic reaction temperature by a heating tube and an oxygen supply tube. At the same time, oxygen is injected into the oxygen supply tube, which promotes the oxidation of CO in the exhaust gas to CO and the decomposition of VOCs into CO and H2O, thereby facilitating the decomposition of organic matter such as CO and VOCs and achieving the complete harmless treatment of organic matter.

A low-cost concentration and stepwise extraction and utilization process for valuable components of coal mine water is disclosed. This process employs pretreatment of mine water using drift flotation and flocculation sedimentation to remove impurities. Through oblique light correction to enhance solar radiation energy, film overflow heating of the mine water, flash distillation of hot mine water, and condensation collection, the mine water is concentrated at low cost within a solar distillation device. Metal and heavy metal components are extracted from the mine water through solid-phase and liquid-phase chemical conversions and utilized as resources. Highly toxic chromium and radioactive uranium are captured from the mine water using an adsorption + reduction method. Arsenic compounds are adsorbed using a loaded fluoride ion adsorbent. This process achieves low-energy consumption, resource recovery, and harmlessness in mine water treatment, enabling clean and circular utilization of the mine water. It represents a technology for fundamentally controlling mine wastewater pollution.
