Problems solved by technology

[0003] Among them, the cyclone dust collector has a simple structure and is easy to use, which is very suitable for preliminary dust removal treatment. However, due to the limitations of its own structure, the cyclone dust collector has low processing efficiency, so it will bring greater operating pressure to subsequent processing equipment, resulting in The failure rate of the follow-up processing equipment increases, the consumables increase, and even lead to the problem that the final discharge exceeds the standard. At present, in order to increase the processing efficiency of the cyclone dust collector, a spray device is installed inside the cyclone dust collector to increase the agglomeration effect of the particles, thereby improving The treatment efficiency of dust removal, but because the internal spray will affect the airflow direction in the cyclone collector and affect the dust removal effect, so this method is not ideal

Embodiment Construction

[0049] In order to clearly describe the technical characteristics of the present plan, the plan will be described below by way of example.

[0050] See Figures 1 to 7 As shown, the present invention is a hazardous waste disposal of flue gas purification process route and system, and is effectively improved the processing effect of the cyclone dust collector for pretreatment of flue gas into the cyclone collector.

[0051] Hazardous waste disposal flue gas purification new process route includes the following steps:

[0052] Step S1: Collect the smoke into the vacuum collection box 1, when the pressure is at the same pressure in the box, turn off the inlet valve, physical compression to the flue gas to improve the concentration of the flue gas;

[0053] Step S2: When the compressed flue gas concentration satisfies the setting standard, stop the compression and exterior exhaust gas, the discharge flue gas is sprayed to increase the mutual cohesive effect of the particulate matter in...

Abstract

The invention provides a novel process route and system for flue gas purification in hazardous waste treatment, belongs to the technical field of activated carbon regeneration, and effectively solves the problem of low removal efficiency of a cyclone dust collector. According to the technical scheme, the technological process comprises the steps that smoke dust is collected into a vacuum collection box, smoke is compressed to increase the smoke concentration, spraying is conducted after the smoke concentration meets the set standard, then the smoke enters a cyclone dust collector to be subjected to dust removal treatment, and if smoke at an air outlet of the dust collector exceeds the preset value, and the smoke is discharged into a vacuum temporary storage box, then is discharged into a spraying pipeline, is sprayed, secondarily enters the cyclone dust collector, is treated, and is discharged after reaching the standard. The treatment effect of the cyclone dust collector is improved by providing the pretreatment system for the flue gas generated in the activated carbon regeneration process.

Description

Technical field [0001] The present invention relates to activated carbon regeneration technologies, and particularly to a new hazardous waste flue gas cleaning system and process route. Background technique [0002] After the flue gas needs to be discharged to the systematic treatment of the activated carbon regeneration process, the regeneration of the main pollutants in the flue gas dust, acidic components (SO2, NO2, HCl, HF), CO, dioxins, smoke gas purification system was cooled to complete the combustion fumes, dust and deacidification, and the need to control harmful substances such as dioxins, the flue gas treatment process regenerator flue gas generated in the furnace and is collected and dried through cyclones after initial dust into the secondary combustion chamber for combustion after the high-temperature denitration, cooled, deacidification, secondary dedusting, defogging, activated carbon adsorption, and the like after the removal of white smoke during efflux. [0003...
