Problems solved by technology

[0003] Existing technology example 1. Whether the furnace is designed with adiabatic design or arranged with a membrane-type water-cooled wall heating surface, it still plays the role of traditional heat transfer and flue gas passage for high-temperature flue gas, and has no function of purifying high-temperature flue gas. ; Prior Art Example 2 The main function of the molten salt in the molten salt regenerator is the heat transfer medium, which is similar to water (steam) and organic heat carrier (heat transfer oil)

Embodiment 1

[0018] This example provides a preparation method for the special molten salt patch for adsorbing VOCs solid waste regenerative fluidized combustion furnace. In step 1, the preparation is weighed according to the proportion of the following components: circulating fluidized bed coal-fired boiler fly ash 100 part, 15 parts of potassium sulfate, 15 parts of sodium sulfate, 3 parts of stainless steel fibers, 3 parts of p-tert-butylphenol formaldehyde resins, and the components are calculated in parts by weight; step 2, enter the roller compactor for mixing evenly after the preparation of materials is completed, Both the fixed roll and the movable roll of the roller press should be smooth grinding rolls, and the feeding sequence is that the circulating fluidized bed coal-fired boiler fly ash, potassium sulfate and sodium sulfate are first added and mixed for 3 minutes, and then stainless steel fibers are added and mixed for 2 minutes. Minutes, finally add p-tert-butylphenol formald...

Abstract

The invention relates to the technical field of volatile organic compound waste gas treatment, in particular to a preparation method of fused salt patch for adsorbing VOCs solid waste and special for a thermal-storage fluidized combustion furnace. The preparation method is characterized by comprising the steps of mixing based on a roller press, press forming, stationary ageing mixture, curing and drying, vacuum sintering and the like. Pollutants containing Cl-, SO2 and particulate matter in high temperature flue gas can be effectively purified, high-temperature corrosion and erosion abrasion to heated-surface metal components are avoided and decreased, and the service life of the heated-surface metal components is prolonged.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment of volatile organic compounds, in particular to a preparation method of a special molten salt patch for absorbing VOCs solid waste heat storage fluidized combustion furnace. Background technique [0002] Gaseous pollutants emitted by industry are the main source of atmospheric environmental pollutants, among which volatile organic compound waste gas (VOCs) is a gaseous pollutant that is seriously harmful to the environment, and it is also an occupational hazard that affects the health of operators in the workplace It is widely derived from chemical industries such as paints, coatings, coatings, lubricants, and rubber. Due to its huge destructive effect on the human body and the natural environment, the country has issued relevant laws and regulations to strictly control its governance and emissions. At present, the commonly used treatment methods of organic waste gas treatment technol...
