Embodiment 1

[0048] In this example, if Figure 1A As shown, the arrangement of the serpentine tubes 2 on the header 1 adopts the method of "four in and four out", that is to say, the number of serpentine tubes 2 is four, and there are four inlets and four outlets. , partition 5 divides header 1 into multiple subsets, such as Figure 1A shown. Four sets of independent serpentine tubes 2 are evenly arranged on the side of the central cylinder along the vertical direction to form a cooling wall. The number of sets of independently arranged serpentine tubes 2 is mainly determined according to the volume of the central cylinder and the winding times of the serpentine tubes 2 . The cooling medium in the serpentine tube 2 can adopt steam cooling, water cooling, oil cooling and air cooling, and at the same time, the cooling medium in the serpentine tube 2 flows evenly. There are mainly two forms for the arrangement of the inlet port 21 and the outlet port 22 of the serpentine tube 2, as Figure...

Embodiment 2

[0057] Figure 2A It is a schematic structural diagram of the cooling central cylinder of the second embodiment of the present invention, Figure 2B It is a schematic diagram of the implementation of the cooling central cylinder in the second embodiment of the present invention, Figure 2C It is a schematic diagram of another implementation of the cooling central cylinder in the second embodiment of the present invention. Such as Figure 2A , Figure 2B and Figure 2C The arrangement of the serpentine tubes 2 on the header of the cooling-type central cylinder adopts the method of "three ins and three outs", that is to say, the number of serpentine tubes 2 is three, and there are three inlets 21 and three outlets. Nozzle 22, partition 5 divides header 1 into four subset headers (see Figure 2B ), or partition 5 divides header 1 into six subset headers (see Figure 2C ), its specific implementation is similar to Embodiment 1, and will not be repeated here.

Abstract

A cooling central cylinder, comprising: a header, a central cylinder body and at least one serpentine tube, wherein the header is arranged on the upper part of the central cylinder body, and is in an annular structure, which contains at least a section of the Each of the sub-collectors is respectively provided with an inlet and an outlet; at least one serpentine tube is placed side by side along the vertical direction on the outer wall of the central cylinder body, and each of the serpentine tubes includes two nozzles: the inlet tube The pipe inlet is connected to the outlet, and the pipe outlet is connected to the inlet. The present invention adopts a header, and divides the header into multiple sub-collectors, which reduces the load of hanging and supporting the cooling central tube, and effectively reduces the cooling capacity through the channel between the serpentine tube and the sub-collectors. The operating temperature of the central cylinder.

Description

technical field [0001] The invention relates to the technical field of a cooling device for a circulating fluidized bed cyclone separator, in particular to a cooling central cylinder. Background technique [0002] The cyclone separator is a crucial device of the circulating fluidized bed boiler, and the central cylinder is one of the important parts of the cyclone separator. The central tube of the circulating fluidized bed boiler cyclone separator is in a harsh operating environment with high flue gas temperature, fast flue gas flow rate, severe rotating edge wear, and high particle concentration. During long-term operation, the wear resistance of the central tube is likely to weaken , severe high temperature wear and deformation, and short material life seriously affect the safety of circulating fluidized bed boiler cyclone separator operation and other issues. [0003] The central cylinder of the circulating fluidized bed boiler cyclone separator is prone to high tempera...
