Abstract
The utility model discloses calcium-spurting desulfurization equipment of a circulating fluidized bed boiler. In a majority of traditional circulating fluidized bed boilers, a desulfurizing agent is simply mixed with coal directly, and the dry desulfurization measure in such a way has low calcium utilization ratio and low desulfuration efficiency due to poor continuity, large desulfurization agent particle size, uneven mixing and the like, therefore, requirements of atmosphere pollutant emission regulations on boilers and fossil-fired power plants are difficult to meet. The calcium-spurting desulfurization equipment comprises a cabin body (7); the lower part of the cabin body is connected with a power-driven airlock feeder (10); the lower part of the power-driven airlock feeder (10) is connected with a controllable rotating feeding valve (11); the lower part of the controllable rotating feeding valve (11) is connected with an ejector (12) which is connected with a high-voltage conveying fan (1) and a distributor (13); the front part of the distributor (13) is connected with a ejecting pipe (14) which is connected with a boiler hearth (16), and the tail part of the boiler furnace is provided with a steam feeding back device (15). The utility model is used for a calcium-spurting desulfurization system inside the circulating fluidized bed boiler.
Description
Technical field:
The utility model relates to a kind of CFBB calcium injection and desulfurization equipment.
Background technology:
CFBB is with its superior environmental protection characteristic, fuel tolerance and good operation characteristic, and is widely used in power system and the central heating system.Most of CFBB directly mixes desulfurizing agent and coal simply, this dry desulfurization measure because operation poor continuity, desulfurizing agent granularity big, mix unequal, calcium utilization and desulfuration efficiency are very low, are difficult to satisfy the requirement of boiler and thermal power plant's Air Pollutant Emission rules.
Summary of the invention:
The purpose of this utility model be for CFBB provides a cover can safe and stable operation, desulfuration in furnace agent mixed characteristic is good, have than high desulfurization efficiency, conserve water resource, and the dry method in-furnace calcium spraying desulfurization that the initial stage drops into and operation and maintenance cost is lower equipment.
Above-mentioned purpose realizes by following technical scheme:
CFBB calcium injection and desulfurization equipment, its composition comprises: warehouse, described warehouse bottom connects electronic flapper, described electronic flapper bottom connects controlled rotatory feeder valve, described controlled rotatory feeder valve bottom connects injector, and described injector connects high-pressure delivery blower fan and distributor, the anterior playpipe that connects of described distributor, described playpipe connects boiler furnace, and described boiler furnace afterbody is provided with the steam feeding back device.
Described CFBB calcium injection and desulfurization equipment, described warehouse comprises feed pipe, deduster, the pressure limiting valve at top, the cone of described warehouse side lower part comprises and is attached to its outside gasification board and heater, described heater rear portion connects the gasification blower fan, and desulfurizing agent is equipped with in described warehouse inside.
The beneficial effects of the utility model:
1. the utility model is little than the wet desulphurization device floor space, and disposable input cost is low, and than other dry desulfurization device desulfuration efficiency height, desulfurization degree can reach more than 90% when the utility model normally moved.Can realize desulfurizing agent based on fuel sulfur content Synchronization Control, when guaranteeing desulfuration efficiency, save desulfurizing agent to greatest extent.
2. the steam feeding back device is as the means that further improve desulfuration efficiency, stoppage in transit does not influence the operation of whole desulfurization equipment separately, can be according to country to boiler and thermal power plant's atmosphere pollutants emission standards requirement, the input and the stoppage in transit of control steam feeding back device, the too high business economic benefit that influences of disposable input can be avoided, the desulphurization system operating cost can be further reduced again.
3. the utility model is applicable to all kinds CFBB, and desulfurizing agent uses the back to generate desulfurization product and discharges out of the furnace with the big slag of boiler, is the raw material of industry of other industries, can directly utilize, and does not cause secondary pollution, has higher promotion and use value.

Accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
CFBB calcium injection and desulfurization equipment, its composition comprises: warehouse 7, described warehouse bottom connects electronic flapper 10, described electronic flapper bottom connects controlled rotatory feeder valve 11, described controlled rotatory feeder valve bottom connects injector 12, and described injector connects high-pressure delivery blower fan 1 and distributor 13, the anterior playpipe 14 that connects of described distributor, described playpipe connects boiler furnace 16, and described boiler furnace afterbody is provided with steam feeding back device 15.
Embodiment 2:
Above-mentioned CFBB calcium injection and desulfurization equipment, described warehouse comprises feed pipe 4, deduster 5, the pressure limiting valve 6 at top, described warehouse side lower part cone is provided with gasification board 9, described gasification board rear portion is provided with heater 3, described heater rear portion is provided with gasification blower fan 2, and there is desulfurizing agent 8 described warehouse inside.Described desulfurizing agent is the spherical or lime stone powder in irregular shape by certain grain size distribution.The used steam of described steam feeding back device is the steam turbine exhaust steam.
Before the work, by feed pipe 4 warehouse 7 is filled with desulfurizing agent 8, start by sequence gasification blower fan 2 and heater 3, during work, start conveying fan 1 earlier, start electronic flapper 10 then, controlled rotatory feeder valve 11, mix with carrying wind at injector 12 places, after distributor 13 distributes, spray into burner hearth by playpipe 14, in stove, evenly mix with diffusion after, the sulfur dioxide that generates with coal combustion fully contacts the generation chemical reaction, generates solid-state desulfurization product and discharges out of the furnace, thereby realize the desulfurization purpose, and desulfurizing agent is in cyclic process, can pass through steam feeding back device 15, improve the activity of desulfurizing agent 8, and further improve system's desulfuration efficiency and sorbent utilization.The continuous free of discontinuities of sweetening process only consumes a small amount of steam turbine exhaust steam, non-secondary pollution, no industrial wastewater discharge when steam feeding back device 15 comes into operation.
