Embodiment Construction

[0019] specific implementation plan

[0020] Radial jet structured cyclone separator (such as Figure 4 As shown), a radial impeller 4 is fixed on the top of a spiral flow separation outdoor cylinder 6 installed vertically on the axis, and the axis of the radial impeller 4 coincides with the axis of the outer cylinder 6 . An inner cylinder 7 is coaxially installed in the outer cylinder 6, and two concentric cylinders with different diameters form a spiral flow separation chamber 8. The uppermost end of the inner cylinder 7 is fixed on the disc of the radial impeller 4 . On the top of the spiral flow separation chamber 8, a group of spiral guide vanes 5 are evenly installed in the circumferential direction, and the uppermost end of each spiral guide vane 5 is fixedly connected with the blades of the radial impeller 4 respectively, and is respectively connected with the spiral flow separation chamber 8. The outer cylinder and inner cylinder correspond to close contact. The pu...

Abstract

The invention discloses a radial spray regular cyclone separator which mainly comprises an inner cylinder and an outer cylinder, wherein the inner cylinder and the outer cylinder are installed coaxially; a separating chamber is formed between the side walls of the inner cylinder and the outer cylinder; spiral guide blades are installed in the separating chamber; the upper end of the inner cylinder is communicated with an air outlet pipe; an annular channel communicated with the separating chamber is formed between the air outlet pipe and a cylindrical flow regulation pipe sleeved outside the air outlet pipe; a radial impeller is installed in a cavity between the upper end of the outer cylinder and the upper end of the inner cylinder by taking the air outlet pipe as a center; and dust laden air flow enters from the annular channel, is guided to the inner wall of the outer cylinder by the radial impeller, and then enters the separating chamber by turning 90 degrees. In the invention, the solid particles are separated by the combined action of radial spray inertia force and spiral rotation centrifugal force, the centrifugal separation force is enhanced, and the dust laden air flow does regular spiral rotational movement in the spiral flow separating chamber, thus preventing whirlpool caused by air shock in the separating chamber and improving the separation efficiency.

Description

technical field [0001] The invention relates to the technical field of gas (liquid) solid separation, in particular to a radial jet regular spiral flow separator, which is mainly used in petroleum, chemical industry, medicine, iron and steel smelting, non-ferrous metal smelting, cement plants, thermal power plants, and grain processing plants , Coking plants and other industries dust removal system. Background technique [0002] The gas-solid separation of dust-laden airflow is the main process in petroleum, chemical, pharmaceutical, mining, metallurgy, cement, thermal power, grain processing and other industries. Reducing air pollution from various types of industrial dust is an environmental protection issue that the world attaches great importance to. [0003] In the above fields, the cyclone separator is the most widely used separation equipment. The basic principle of the cyclone separator is that the dust-laden airflow enters the cylinder along the tangent line to ma...
