This paper presents the fast rotary dirt remover that we have researched and made. Mathematical model of the fast rotary dirt remove is established by theory of infinitesimal calculus. Formulas of velocity distribution and removing efficiency are derived. Tests have been carried out to study the performance of the fast rotary dirt remover Experimental results are found to be close to the theory calculation data.
The fast rotary dirt remover has many advantages, such as high removing efficiency ,small coefficient of local resistance
,no clogging up ,so that it is widely used in heat water heating systems , cool and cooling water system of air conditioning .Fast rotary dirt remover can protect refrigerators , boilers and so on and reduce operation consumption energy of systems.
