Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to an environmentally friendly chemical waste gas treatment device for polyphosphoric acid processing. Background Art

[0002] Polyphosphoric acid is a colorless, transparent, viscous liquid that is corrosive and belongs to the class of dipolar inorganic acidic corrosives. Polyphosphoric acid is a protonic acid that can dissolve a variety of low-molecular and high-molecular organic compounds. It is used as a dehydrating agent, cyclizing agent, and acylating agent in organic synthesis. It is a catalyst or solvent for condensation, cyclization, rearrangement, substitution and other reactions.

[0003] Polyphosphoric acid will generate waste gas during the production process. The waste gas needs to be treated before it can be discharged to avoid environmental pollution. The waste gas treatment device generally treats the waste gas by spraying water, so that the chemical substances in the chemical waste gas react with the spray water to effectively remove the chemical substances, and then cooperates with other treatment processes to ensure the purification effect of the waste gas. The spray head that sprays the spray water is installed inside the waste gas treatment device. When the spray head is damaged or blocked and needs to be replaced or cleaned, it is very troublesome to install and remove the spray head. The device needs to be opened and the spray head needs to be installed and removed inside the device. Due to the limitations of various components inside the device, the tools are inconvenient to use and the installation and removal operations are not convenient enough, which not only makes the work intensity of the staff greater, but also makes the installation and removal efficiency of the spray head relatively low, thereby affecting the use of the waste gas treatment device.
