Problems solved by technology

In addition, the deposition of alkaline metal compounds such as Na and K in the garbage adheres to the metal surface, which will aggravate the corrosion of the metal.
In order to effectively solve the problem of high-temperature corrosion of the superheater caused by HCl gas, some manufacturers currently place the high-temperature superheater in the fluidization air chamber of the feeder. , The flow is slow and the problem of tube burst occurs

Embodiment Construction

[0014] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings.

[0015] Accompanying drawing is the schematic diagram of a kind of specific embodiment of the one-inlet and two-outlet adjustable feeder of the present invention, and the one-inlet and double-outlet adjustable feeder includes the material leg 1 that communicates with the lower part of the cyclone separator, and the material leg 1 The lower part is equipped with a fluidization air chamber, a material return air chamber, a loose air chamber, a material return pipe and a high temperature superheater. The fluidization air chamber is divided into a left fluidization air chamber 8 and a right fluidization air chamber 5; The air chamber is divided into the left return air chamber 6 and the right return air chamber 4; the loose air chamber is divided into the left loose air chamber 7 and the right loose air chamber 3; the return pipe is divid...

Abstract

The invention discloses a one-in two-out adjustable recycle device. The recycle device comprises a dipleg communicated with a lower part of a cyclone separator, and left and right fluidized air chambers, left and right recycle air chambers, and left and right aeration air chambers arranged at the lower part of the dipleg. A high-temperature superheater is arranged in the right fluidized air chamber. When a boiler operates in a rated load or overload mode, aeration air and recycle air at one side arranged with the high-temperature superheater are turned on, the high-temperature superheater and flowing high-temperature solid material exchange heat, and then the material subjected to heat exchange returns to a hearth via a material-returning pipe for recycling. When the boiler operates in an underload mode, the aeration air and recycle air at the other side without arranging the high-temperature superheater are turned on, and the high-temperature solid material returns to the hearth via the fluidized air chamber at the other side without arranging the high-temperature superheater and the material-returning pipe for recycling, thus, the high-temperature solid material doesn't exchange heat with the high-temperature superheater at the underload, to thereby prevent pipe explosion of the high-temperature superheater.

Description

[0001] technical field [0002] The invention belongs to the technical field of circulating fluidized bed boilers, in particular to a circulating fluidized bed waste incineration boiler. Background technique [0003] Waste incineration, as an effective means to realize the reduction, harmless and resourceful treatment of urban domestic waste, has been more and more widely used in my country, especially in large and medium-sized cities and coastal areas, because land for waste landfill is becoming more and more difficult It is difficult to find and treat leachate from landfills; while garbage is used for composting, the effective fertilizer content is low, and the heavy metals and toxic chemicals contained in garbage will affect the quality of compost and the degree of solid waste reduction. Therefore, the application of waste incineration treatment technology has been developed rapidly. With the development of industrial production and the improvement of people's living stand...
