Problems solved by technology
[0002] Waste incineration power generation is the work of introducing waste plants and waste incineration equipment, digesting, absorbing and re-innovating; because the working environment of the induced draft fan used in the incineration power plant is relatively harsh, and usually contains sulfur dioxide and flue gas, etc., the wear resistance of the impeller of the induced draft fan It has high requirements for corrosion resistance and anti-corrosion. The traditional anti-corrosion measures include ceramic paste, rubber lining, etc., but the price is high and the processing is troublesome.

The invention discloses an anti-abrasion and anti-corrosion impeller for an induced draft fan of a waste incineration power plant. The anti-abrasion and anti-corrosion impeller comprises a rear plate, blades and a front plate. Guard plates are arranged at inlets of working surfaces of the blades and are close to the rear plate, and an anti-corrosion paint coating is arranged on each blade. The anti-abrasion and anti-corrosion impeller solves problems in the prior art, the guard plates are additionally arranged at quick-wearing positions of the impeller to improve the anti-abrasion performance of the impeller, and anti-corrosion paint is coated on the impeller, so that the anti-corrosion performance of the impeller is improved to a great extent. The anti-abrasion and anti-corrosion impeller is simple in structure, high in anti-corrosion performance and suitable for wide utilization, and the cost of the anti-abrasion and anti-corrosion impeller is greatly lowered.
Description
technical field [0001] The invention relates to an induced fan of a waste incineration power plant, in particular to an anti-wear and anticorrosion impeller for the induced fan of a waste incineration power plant. Background technique [0002] Waste incineration power generation is the work of introducing waste plants and waste incineration equipment, digesting, absorbing and re-innovating; because the working environment of the induced draft fan used in the incineration power plant is relatively harsh, it usually contains sulfur dioxide and flue gas, etc. It has high requirements for corrosion resistance and anti-corrosion. The traditional anti-corrosion measures include ceramic paste and rubber lining, but the price is high and the processing is troublesome. Contents of the invention [0003] Purpose of the invention: In order to solve the problems in the prior art, the present invention provides a wear-resistant and anti-corrosion impeller with good anti-corrosion perfo...
