Magnetized foam dust collector with recyclable foam liquid and method of using the same

Abstract

A magnetized foam dust remover with recyclable foam liquid and its use method. The magnetized foam dust remover includes an air guide tube, and a foaming agent storage tank is arranged on the outside of the air guide tube. The foaming agent storage tank passes through a first liquid suction pipe and The two-stage proportional mixer is connected, the two-stage proportional mixer is connected to the self-priming magnetic foamer, and the self-priming magnetic foamer is connected to the nozzle or / and the drainage screen through the magnetic foam transfer pipe, and the drainage screen There is an ultrasonic defoamer behind the ultrasonic defoamer, a screw extruder under the ultrasonic defoamer, and a recovery liquid storage tank under the screw extruder, which is connected to a two-stage proportional mixer. The magnetized foam produced by the invention can capture the dust in the dust-laden airflow, and can realize the separation of the dust-liquid of the dust-laden foam liquid. After the dust is enriched, it can be stored in a centralized manner, and the foam liquid can be further recycled, avoiding the secondary flying of the dust. It can improve the utilization efficiency of the blowing agent, effectively reduce the operation cost of the device, and avoid the adverse effect of random discharge of foam on the working environment.

Description

technical field [0001] The invention relates to the technical field of dust control, in particular to a magnetized foam dust remover with recyclable foam liquid and a use method thereof. Background technique [0002] Coal dust can cause pneumoconiosis. According to the "National Occupational Disease Reports in 2014" issued by the National Health and Family Planning Commission, the number of reported cases of pneumoconiosis accounted for 89.66% of the total number of reported occupational diseases, and 94.21% of the new cases of pneumoconiosis were coal workers' pneumoconiosis. and silicosis. At present, the annual death toll due to pneumoconiosis in my country's coal mines has obviously exceeded the sum of the death toll from fire, gas and other accidents. Coal dust can also cause coal dust explosion. Coal dust explosion is the accident with the largest number of deaths in coal mines. From 1970 to 2014, 4,648 people died in 105 coal dust explosion accidents or gas and coal ...

Problems solved by technology

Among them, CN201110208126.4 ultra-micro magnetized foam drilling dust collector is a dust removal device applied to the specific location of drilling dust removal. The foam liquid is configured in advance and poured into the dust removal box before dust removal. The foam is produced using gas return air and Foam net, due to the different gas pressure in different application locations, the gas return air is unstable during the application of the dust collector, which affects the foam production and dust removal effect, and most of the coal dust stays in the dust collector, which needs to be cleaned regularly

CN201310694372.4 A two-fluid magnetized foam dust suppression system and method are similar to CN201110208126.4 ultra-micro magnetized foam drilling dust collector, the foam liquid is still a one-time application, because the foam contains surfactants and other chemicals, if it cannot be recycled , which will lead to higher operating costs, and the direct discharge of dusty foam liquid will also have a certain impact on the operating environment
