Abstract
The utility model relates to a cooled central cylinder, in particular to a central cylinder for a circulating fluidized bed separator, and belongs to the technical field of cooling devices. A central cylinder of an existing circulating fluidized bed separator mainly is made from alloy steel hanging board material. The central cylinder is positioned in the condition that the temperature of the smoke is high, smoke flow velocity is high, and the concentration of particulate matter is large, so that problems that wear resistance is poor, the service life is not long, and the transformation is serious are caused, so that the efficiency of the circulating fluidized bed boiler is low, the tail wear is serious, the combustion is instable, and a plurality of parameters can not meet the requirement of the design parameters. The cooled central cylinder is formed by a U shaped tube which can conduct heat exchange, the temperature of the metal of the central cylinder is effectively reduced, all the performances of the metal can be improved, and refractory and wear-resistant castable is attached on the peripheral surface of the metal at the same time, so that the problems of central cylinder transform and short service life can be thoroughly resolved.
Description
[technical field]
The utility model is a kind of cooled central tube, and the central tube of cyclone separator belongs to the cooling device field in particularly a kind of circulating fluid bed garbage furnace, the circulating fluidized bed combustion coal stove.
[background technology]
Cyclone separator is very important parts in CFBB, and the critical piece of cyclone separator is a central tube.The effect of cyclone separator is that thickness material in the flue gas of from boiler, discharging is separated.Thick material returns combustion chamber continuation participation burning as a kind of fluidisation carrier and heat carrier.Thin material carries out being discharged by chimney after treatment after the heat exchange with flue gas.Central tube in China's cyclone separator of circulating fluidized bed boiler mainly uses the link plate formula now, and the material of link plate is a steel alloy.Central tube is in flue-gas temperature height, flue gas flow rate is fast, particle concentration the is big running environment; Central tube because cause under rugged environment that it is not wear-resisting, service life is long, distortion is serious, thereby cause the efficient of CFBB on the low side, afterbody serious wear, combustion instability, parameters do not reach design load.
[utility model content]
Be prone to problems such as not wear-resisting, that service life is not long, distortion is serious in order to overcome existing steel alloy central tube; It is a kind of by the cooled central tube that is made up of U type pipe that can carry out heat exchange that the utility model provides; Reduced the temperature of central tube effectively; Improve each item performance, on wall inside and outside the central tube barrel, laid the fire-resistant abrasion-proof pouring material simultaneously, thoroughly solved the problem that central tube is out of shape and service life is short.For this reason, the utility model adopts following technical scheme:
The cooled central tube; Comprise inlet header case and outlet collection case, it is characterized in that: also comprise some U type pipes of being processed by Heat Conduction Material, each U type pipe compartment of terrain is located on the same circumference and surrounds the formation tubular; A mouth of pipe of U type pipe is communicated with the inlet header case, and another mouth of pipe is communicated with outlet collection case.Cooling medium flows out from the inlet header case, through U type pipe, U type pipe is cooled off laggard inlet/outlet collection case.Previous designs has reduced the temperature of central tube effectively, has improved each item performance of central tube.
The cooled central tube is characterized in that: be connected to form cylindrical wall with sheet material between described each U type pipe.Previous designs can improve the integral rigidity of cooled central tube, prevents the central tube distortion, guarantees the separative efficiency of separator.
The cooled central tube is characterized in that: the described cylindrical wall outside and inboard are provided with Fire and abrasion resistant material.Arranged outside Fire and abrasion resistant material in cylindrical wall can prevent the barrel wearing and tearing and reduce caloric receptivity, can effectively solve the problem that central tube is out of shape and service life is short.
The cooled central tube is characterized in that: described cylindrical wall arranged outside has some annular comb plate, comb joints.Annular comb plate, comb joint is set, makes U type tube bank fixed-site, avoid distortion.
The cooled central tube is characterized in that: each U type pipe evenly distributes.U type pipe evenly distributes, and each pipe is heated evenly, avoids occurring being heated the inhomogeneous device damage phenomenon that occurs.
The cooled central tube that the utility model provides; Through improving structural design; Reduce the central tube self-temperature, improved the antiwear property of central tube, improved the non-deformability of central tube; Effectively solve wearing and tearing, the problem on deformation of existing central tube, and then solved not long problem in service life.Guarantee the continous-stable operation of boiler, improved the combustion stability of boiler, heat-economy, guaranteed that the separative efficiency of cyclone separator has alleviated the wearing and tearing of back-end surfaces, thoroughly solved cyclone separator central tube maintenance replacing problem.
