Technical description: specific devices need to burn diesel fuel, it will produce a lot of smoke, which not only contains a lot of smoke dust, and contains a large number of incomplete combustion of diesel fuel. If you let the flue gas directly into the atmosphere containing this is bound to cause a lot of pollution to the environment, in order to protect the environment, it must be processed. How to design a low investment, high collection efficiency, the new dust removal system for diesel combustion equipment, is an important topic in the field of dust. The new technique is: to provide a dust removing system for a diesel combustion device, it is possible to overcome the adverse effects of a large amount of flue gas dedusting oil system. To achieve the above purpose, the utility has designed a new set by the venturi inlet, two-way feeder, dusting tube consisting of fly ash can assist oil circulation system. This patented technology has been applied in a special environment for the first time exported to Southeast Asia and other places.
