Problems solved by technology

[0004] The boiler steam soot blowing system disclosed in this patent document not only has a complex structure, but also it is difficult to blow the soot in the center of the air preheater tube bundle by steam soot blowing. The ash solidifies, causing the air preheater to fail, resulting in a reduction in the output of the entire boiler and a decrease in efficiency

Abstract

The invention discloses an electric hoist device for a fluidized bed boiler and belongs to the technical field of fluidized bed boiler equipment. The device comprises a supporting frame and is characterized in that an electric motor, a speed reducer, a zipper hoist and a coupler are arranged on the supporting frame, the zipper hoist comprises a chain wheel and a chain wound around the chain wheel, the electric motor is connected with the speed reducer, the speed reducer is connected with the chain wheel of the zipper hoist through the coupler, and a sand draining cart is connected to the chain of the zipper hoist. By the adoption of the device, sand can be transported effectively, the utilization rate of sand is increased, and as a result, high heat exchange efficiency of the fluidized bed boiler is guaranteed, the steam rate of the fluidized bed boiler is increased, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fluidized bed boiler equipment, in particular to an electric hoist device for a fluidized bed boiler. Background technique [0002] The circulating fluidized bed boiler adopts a single drum and natural circulation mode, and is generally divided into two shafts at the front and the rear. The front shaft is a general suspension structure, surrounded by membrane water cooling walls. From bottom to top, it is the primary air chamber, dense phase area, and dilute phase area. The tail shaft adopts a supporting structure, and the two shafts are connected by a vertical cyclone separator, and the lower part of the separator is connected with a return device and an ash cooler. The interior of the combustion chamber and the separator are equipped with anti-wear linings, the front shaft is equipped with an Ao tube furnace wall, an external metal guard plate is used, and the tail shaft is equipped with a light furna...
