Room temperature droplet micro-reactor and method of producing zirconium dioxide gel microspheres

The invention provides a room temperature droplet micro-reactor and a method of producing zirconium dioxide gel microspheres. The room temperature droplet micro-reactor comprises an internal phase fluid inject pipe, an external phase fluid inject pipe, a collection pipe, and a continuous phase fluid inlet pipe. The internal phase fluid inject pipe is provided with a first inlet, a first outlet and an internal phase fluid channel. The external phase fluid inject pipe sleeves outside the internal phase fluid inject pipe. An inlet end of the collection pipe sleeves the external side of an outlet end of the external phase fluid inject pipe. A third outlet is formed by the inner periphery of the collection pipe and the outer periphery of the external phase fluid inject pipe. The continuous phase fluid inlet pipe sleeves the external sides of the external phase fluid inject pipe and the collection pipe. A continuous fluid channel is formed by the inner periphery of the continuous phase fluid inlet pipe and the outer periphery of the external phase fluid inject pipe. The continuous phase fluid inlet pipe is provided with a third inlet and the third outlet. The room temperature droplet micro-reactor can be used for preparing the gel microspheres having excellent sphericity degree and uniformity.
