Description

Technical Field

[0001] The utility model relates to the technical field of pure oxygen gasifiers, and particularly relates to a waste gas treatment device for a pure oxygen gasifier. Background Art

[0002] A pure oxygen gasifier is a device that uses pure oxygen as an oxidant to convert solid or liquid fuels into syngas (mainly composed of carbon monoxide and hydrogen) under high temperature and high pressure conditions. This technology is widely used in the fields of chemical industry, metallurgy, energy, etc., and is favored for its high efficiency and environmental protection characteristics. However, a large amount of waste gas is generated during the operation of a pure oxygen gasifier. These waste gases contain components such as dust, soot, and harmful gases. If directly discharged without proper treatment, it will cause serious pollution to the environment and may pose a hazard to human health.

[0003] Deficiencies of Existing Waste Gas Treatment Devices for Pure Oxygen Gasifiers

[0004] Limited treatment efficiency: Existing waste gas treatment devices often adopt a single treatment method, such as simple filtration or spraying. These methods may not be able to comprehensively remove various harmful components in the waste gas, resulting in low treatment efficiency.

[0005] The filtration system is prone to clogging: Traditional filtration systems lack an automatic cleaning mechanism and are prone to clogging due to the accumulation of impurities, affecting the filtration effect. Frequent manual cleaning is required, increasing the maintenance cost and operation difficulty.

[0006] Therefore, this solution particularly proposes a waste gas treatment device for a pure oxygen gasifier to solve the above problems. Content of the Utility Model
