Description

Technical Field

[0001] The furfural processing wastewater utilization device with a recycling mechanism of the utility model relates to the technical field of furfural processing. Background Art

[0002] Furfural, as an important organic chemical raw material, is widely used in multiple fields such as synthetic resins, pharmaceuticals, pesticides, and spices. Its main production method is obtained by hydrolyzing agricultural wastes such as corncobs under high temperature and high pressure conditions. However, a large amount of wastewater will inevitably be generated in this production process. The wastewater has a complex composition, containing high concentrations of various organic substances such as acetic acid, furfural, alcohols, aldehydes, ketones, esters, and organic acids, as well as some inorganic salts and suspended solids. The presence of these substances makes the wastewater have characteristics such as high COD (chemical oxygen demand), high BOD (biochemical oxygen demand), and high chromaticity. If directly discharged without treatment, it will cause serious pollution to the environment.

[0003] According to the "A Furfural Processing Wastewater Recycling and Utilization Device" disclosed in the Chinese Patent Publication No. CN220745445 U, it includes a bottom plate. One side of the top of the bottom plate is connected with a box body. A filtering component is arranged on the top of the box body. The middle of the top of the bottom plate is provided with a water pump. The other side of the top of the bottom plate is connected with a treatment tank. A chemical dosing component is arranged on the top of the treatment tank. The bottom of one side of the treatment tank is connected with a liquid outlet pipe; the beneficial effect of the utility model is: through the arranged chemical dosing component, by opening the second switching valve, the chemical agent enters the treatment tank from the chemical dosing pipe, purifying the wastewater, which is convenient for operation and reduces the workload of the staff; through the arranged filtering component, the wastewater is added from the liquid inlet pipe. After the wastewater is filtered by the filter cylinder, the residues accumulate in the filter cylinder. The first motor is started to make the rotating shaft rotate, driving the connecting rod and the stirring rod to rotate, stirring and moving the accumulated residues to prevent the residues from blocking the filter cylinder and avoiding affecting the filtering effect.

[0004] However, during the furfural processing process, not only wastewater containing pollutants such as organic substances and heavy metal ions is generated, but also harmful gases such as volatile organic compounds and hydrogen sulfide are released. The above devices often only focus on wastewater treatment and ignore the effective purification of harmful gases, resulting in still prominent environmental pollution problems. Content of the Utility Model
