Embodiment Construction
[0012] Depend on figure 1 , figure 2 It is known that a cyclone separator for a thermoelectric boiler of the present invention is composed of a cone 1, a spiral inlet pipe 2, a spiral outlet pipe 3, and an ash hopper 4, and the spiral inlet pipe 2 is first welded around the lower end of the spiral outlet pipe 3 Together, the outlet at the bottom of the spiral inlet pipe 2 is tangentially welded to the outside of the upper part of the cone 1 and is connected, and the ash hopper 4 is welded to the bottom of the cone 1 and connected to the cone 1. The cone 1, The centerlines of the helical inlet pipe 2, the helical outlet pipe 3 and the ash hopper 4 are concentric.
[0013] During processing, first, according to the requirements of the drawing, bend the long pipe of the seamless steel pipe 1-1 on the outer frame of the two parts of the cone 1 and the spiral inlet pipe 2, and then connect the ring-shaped reinforcing rib 1-4 through the internal transition The tubes are connecte...

Disclosed is a cyclone separator for a thermoelectric boiler. The cyclone separator consists of a cone body (1), a spiral inlet pipe (2), a spiral outlet pipe (3) and an ash bucket (4), wherein the spiral inlet pipe (2) is welded to the lower end of the spiral outlet pipe (3) in a winding mode; an outlet of the lower part of the spiral inlet pipe (2) is welded to the outer part of the upper part of the cone body (1) together in a tangency and communicating mode; the ash bucket (4) is welded to the bottom of the cone body (1) in a communicating mode; and the main bodies of the cone body (1) andthe spiral inlet pipe (2) adopt two sections of bent seamless steel pipes (1-1) to be annularly spliced as framework structures. Since the cyclone separator is used for a large power generation boiler and the size of the cyclone separator is large, a multi-section bending mode is adopted to manufacture the seamless steel pipe framework structure in order to prolong the service life of the whole equipment; and compared with the prior art, the strength of the seamless steel pipe framework structure is higher than that with the adoption of the multi-section welding mode, the number of welding points is reduced by 20% or more, the working efficiency is improved, and the service life of the product is prolonged.
Description
technical field [0001] The invention relates to the field of manufacturing thermoelectric boiler accessories, in particular to a cyclone separator for a thermoelectric boiler. Background technique [0002] Circulating fluidized bed boiler technology is a high-efficiency, low-pollution and clean combustion technology that has developed rapidly in the past ten years. Internationally, this technology has been widely used commercially in the fields of power station boilers, industrial boilers and waste treatment and utilization, and is developing towards large-scale circulating fluidized bed boilers with a scale of hundreds of thousands of kilowatts; domestic research and development in this area And applications are also gradually emerging, and hundreds of circulating fluidized bed boilers have been put into operation or are being manufactured. The boiler adopts a single drum and natural circulation mode, which is generally divided into two shafts at the front and the rear. T...
