Magnetic foam washer capable of recycling foam concentrate and using method thereof

Abstract

The invention provides a magnetic foam dust remover capable of recycling foam concentrate and a using method thereof. The magnetic foam washer comprises a ventilating duct. The ventilating duct is provided with a foamer storage tank on the outer side; the foamer storage tank is connected to a two-stage proportional mixer through a first pipette; the two-stage proportional mixer is connected to self-aspirating magnetic foam making equipment; the self-aspirating magnetic foam making equipment is connected to a nozzle or / and a drainage mesh through a magnetic foam conveying pipe; an ultrasonic foam breaker is arranged behind the drainage mesh; a spiral extrusion device is arranged below the ultrasonic foam breaker; a recovered solution storage tank is arranged below the spiral extrusion device; the recovered solution storage tank is connected to the two-stage proportional mixer. According to the invention, magnetic foam generated by the magnetic foam dust remover is capable of capturing dust in dust-contained airflow, dust and foam separation of dust-contained foam concentrate is realized, dust can be stored in a concentrated way after being gathered, the foam concentrate can be further recycled, re-entrain dust is avoided, the utilization efficiency of the foamer is improved, the operating cost of the device is effectively reduced, and the adverse influence on the working environment caused by discharging foam freely is avoided.

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
