Energy-saving dusting machine

Abstract

The invention relates to the technical field of gas-solid separation, and in particular relates to an energy-saving dusting machine. The energy-saving dusting machine is characterized by comprising a rotor system and a stator shell, wherein the rotor system comprises an impeller assembly; the impeller assembly is arranged on a rotating shaft and is positioned on the upper part of the stator shell; the impeller assembly rotates in the stator shell through the rotating shaft perpendicular to the horizontal plane; the impeller assembly comprises a conical cylinder wheel disc; the conical cylinder wheel disc comprises a rotating disc body and supporting rib plates positioned on the inner side of the disc body; the upper end of the rotating disc body is fixed with a purified air ascending pipe; a gap channel between the supporting rib plates and the purified air ascending pipe form a purified air ascending channel; the periphery of the upper part of the disc body of the conical cylinder wheel disc is a conical surface of which the upper end has large diameter and the lower end has small diameter; an upper seal head of the stator shell is in a conical cylinder shape which is matched with the upper part of the disc body of the conical cylinder wheel disc; and an outer side face of the conical surface of the conical cylinder wheel disc is provided with a plurality of discs which are stacked along the axial direction of the rotating shaft. According to the energy-saving dusting machine, the separation efficiency of superfine particles is improved, the separation energy consumption is reduced, and the equipment investment and occupied area are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of gas-solid separation, in particular to an energy-saving dust collector. Background technique [0002] A large amount of industrial dust will be generated in the production process of steel and non-ferrous metal smelting, thermal power generation, cement production, petroleum, chemical and other industries. The discharge of industrial dust into the atmosphere not only causes a waste of resources, but more importantly, the dust enters the human body and seriously endangers human health and damages plant growth. At present, the industrial dust pollution in China's atmosphere has reached the highest level in the world. Improving the progress of gas-solid separation technology is one of the effective means to solve this problem. [0003] Gas-solid separator (also known as dust collector) is a device that separates solid dust from gas. In terms of separation methods, gas-solid separation technology is genera...

Problems solved by technology

Its disadvantages are: to consume a certain amount of water (or other liquids), and cause secondary pollution to water

However, the impeller and the separation cylinder rotate as a whole, and the dynamic balance of the rotor will be more difficult when dealing with large volumes.

The central exhaust pipe of the lower gas outlet structure may reduce the processing gas volume for the separator of the same structure size
