Abstract
The present invention relates to a circularly spraying type spray head, which belongs to the technical field of spray heads. The circularly spraying type spray head is used for overcoming the using disadvantages that directly spraying type spray heads only can spray forward and have small spraying area. The circularly spraying type spray head is composed of a spray head body, an air inlet, a liquid inlet and a nozzle. The present invention is characterized in that the nozzle is an annular nozzle and is formed by an annular gap which is perpendicular to an axial lead of the spray head body; the liquid inlet is distributed on a side wall forming the annular nozzle. The annular nozzle of the present invention is perpendicular to the travelling direction of gas. After routes are changed by the annular nozzle, a mixture of the gas and liquid is sprayed to the circumference of the spray head in all directions in 360 DEG, and thus, the using disadvantages that the directly spraying type spray heads only can spray forward and have small spraying area are eliminated. The present invention has the characteristics of big differential pressure before and after spraying, refined fog droplets, enhanced combining probability of fog droplets, high temperature containers, the gas and dusty gas, and enhanced cooling effect and dust removing effect. The circularly spraying type spray head is suitable to be used as an appliance for cooling, removing dust and spraying protective coatings.
