Description

Technical Field

[0001] The utility model belongs to the technical field of waste liquid treatment, and in particular relates to a desulfurization device for chemical energy waste liquid. Background Art

[0002] Energy, also known as energy resources or energy resources, is a general term for substances that can generate various energies such as heat, electricity, light and mechanical energy, or can perform work. It refers to various resources that can be directly obtained or processed or converted into useful energy, including primary energy such as coal, crude oil, natural gas, coalbed methane, hydropower, nuclear energy, wind power, solar energy, geothermal energy, biomass energy, and secondary energy such as electricity, heat, and refined oil, as well as other new and renewable energy sources.

[0003] The chemical energy waste liquid desulfurization device in the prior art mostly uses a catalyst to mix with the waste liquid, and uses oxygen to aerate the waste liquid, thereby achieving the purpose of desulfurizing the chemical energy waste liquid. However, in the actual application process, it still has the following shortcomings: the chemical energy waste liquid desulfurization work in the prior art has a poor mixing effect between the catalyst and the waste liquid, which makes the waste liquid and the catalyst not mixed sufficiently, directly affecting the effect of waste liquid desulfurization. The chemical energy waste liquid desulfurization device in the prior art needs to be filtered before it can be discharged because the waste liquid contains more other impurities. The existing waste liquid desulfurization device is prone to clogging during filtration, which greatly reduces the efficiency of the waste liquid desulfurization treatment work.

[0004] The existing patent (application number: CN202221781599.3) proposes a high-efficiency desulfurization device for chemical energy waste liquid, including a support frame, which also includes a filter box. The filter box is fixed to the top side wall of the support frame, and a connected liquid outlet pipe is fixed to the inner side wall of the bottom end of the filter box. The outer side wall of the filter box is provided with a corresponding filter assembly. A plurality of symmetrically distributed support rods are fixed to the top side wall of the filter box. The desulfurization box filter assembly is fixed to the end of the support rod away from the filter box to drive the filter plate to move back and forth up and down, which can fully filter the wastewater and ensure the wastewater treatment effect. It can not only effectively improve the work efficiency of wastewater treatment, but also prevent blockage during wastewater filtration and treatment.

[0005] The existing desulfurization device has the following defects during use: the wastewater is aerated with oxygen to treat sulfides. When oxygen is directly injected into the wastewater, the air bubbles generated are large, which is not conducive to the reaction between oxygen in the air and sulfides, and the efficiency is low.

[0006] In view of this, this application is hereby filed. Utility Model Content
