Abstract

The invention discloses a circulating sand dust blowing device, and belongs to the technical field of boiler dust removing equipment. The circulating sand dust blowing device comprises a sand hopper and an electric hoist connected to a boiler top. The circulating sand dust blowing device is characterized in that a sand blower connected to the top of a tail vertical well and a fluidized bed connected to the bottom of the tail vertical well are further included; the sand blower comprises a speed regulation motor, a belt wheel, a transmission belt, a sand blowing pipe and a bearing connected to the sand blowing pipe; the sand hopper is connected with the sand blowing pipe through a sand inlet pipe; a motor shaft of the speed regulation motor is in transmission connection with the belt wheel; the belt wheel is in transmission connection with the bearing through the transmission belt; the sand blowing pipe communicates with the tail vertical well; a packaging auger driven through a motor is connected to the fluidized bed; and a sand discharge trolley is connected to the electric hoist. According to the circulating sand dust blowing device, dust on a heat exchange component in the tail vertical well can be effectively removed, heat exchange efficiency is improved, and the circulating sand dust blowing device has the beneficial effects of being low in energy consumption, good in dust blowing effect and high in use safety.

Description

technical field [0001] The invention relates to the technical field of boiler ash removal equipment, in particular to a circulating sand soot blowing device. 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 furnace wall. Eight ...
