Description
Technical field
Utility model belongs to Industrial Boiler Technology field, more particularly, to a kind of combined-circulation that burning is cleaned for sludge
Fluidized bed boiler systems.
Background technology
There is substantial amounts of mud to produce in industry, sanitary waste, handling several major ways of these sludge has landfill, heap
Put, burn.With the enhancing of people's environmental consciousness, the landfill having greater environmental impacts and stacking mode are supported by strong
System, the application prospect of burning process is then increasingly expected.Burning is to handle one of most viable method of sludge so far, but
It is that the smell of sludge is not handled in burning process, the stench of sludge is directly flown away in outside air, several public affairs in periphery
In in air be contaminated, have a strong impact on the life of nearby residents.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art to solve sludge malodor problem, energy-conserving and environment-protective there is provided one kind
Be used for sludge clean burn composite circulation fluidizing bed boiler system.
To achieve these goals, the utility model uses following technical scheme：It is a kind of to clean answering for burning for sludge
Close circulating fluidized bed boiler systems, including sludge-tank and boiler, the boiler include boiler body, furnace chamber, sewage sludge feed unit,
Air compartment below furnace chamber, the scum pipe and tail gas treating unit for being connected to lower portion thereof；Between the sludge-tank and boiler
Provided with anti-peculiar smell component, the anti-peculiar smell component is communicated in negative pressure pump including being communicated in the negative pressure pump of the upper boiler, one end
First exhaust tube and the valve for controlling the first exhaust tube to open and close；The first exhaust tube other end connects the sludge-tank.This reality
Directly it is connected with new middle sludge-tank with boiler by the first exhaust tube, the stench of sludge-tank will not leak, and effectively prevent dirt
The gas with foreign flavor that mud is produced flies away；Air-breathing is carried out by negative pressure pump, can be in upper boiler formation negative pressure, it is ensured that the gas of sludge-tank
All it is sucked into boiler, reduces the stench residual in sedimentation basin；Foul smell in sludge-tank is pumped into after boiler furnace, can conduct
First air carries out burning and used, and has saved combustion gas energy consumption, more energy-conserving and environment-protective.
Preferably, the tail gas treating unit is connected including blast pipe, condenser and one end with first exhaust tube
The second logical exhaust tube, the second exhaust tube other end connects the condenser；The tail gas produced in mud drying process is introduced into
Condenser processing, reduces disposal of pollutants；The waste gas that can not be condensed can be pumped into burner hearth by the second exhaust tube, made as wind combustion
With reduction is more saved while pollution；Second exhaust tube is directly communicated to the first exhaust tube, can be entered by same negative pressure pump
Row pumping, parts are reduced, and reduce cost.
Further, the valve includes the flap that valve seat, valve rod and flexible material are made, and has between the valve seat and flap
There is sealing enhancing structure；Sealing enhancing structure can strengthen the sealing effectiveness between flap and valve seat, and long-term use is also not susceptible to
Leakage, service life is long.
Specifically, the sealing enhancing structure is included located at the sealing recess on the valve seat top and positioned at a sealing recess left side
The sealing convex portion of right both sides, the sealing recess has the first inclined plane and the second inclined plane being engaged with the flap respectively；
Because flap is made up of flexible material, when flap is depressed on valve seat, flap will have part to be caught in sealing recess, so as to seal
Contact area increases, and is not susceptible to leakage；Secondly, recess both sides are inclined plane, opposed vertical contact face, crimping contact effect
More preferably, more it is not susceptible to leakage.
Further, the sewage sludge feed unit is including the drainage conduit on sludge-tank, located at the boiler body side
The charging aperture in portion and the passage for connecting the drainage conduit and charging aperture.
Given preferably, the charging aperture is arranged in the height and position of boiler 3/4ths, the passage provided with spiral
Material machine；The position of charging aperture is higher, and sludge is when falling with longer formation, and then moisture in sludge can carry out nature baking
It is dry, it is easy to burn, the use of incendiary material, more energy-conserving and environment-protective can be reduced.
It is preferred that, the sealing convex portion is provided with an at least round convex tendon, and the setting of convex tendon causes the flap of sealing convex portion
Contact area reduce, because pressure is inversely proportional with contact area, then pressure between convex tendon and flap increases, and sealing effectiveness is more
It is good.
In summary, the foul smell suction boiler furnace in sludge-tank is made First air combustion by the utility model by negative pressure pump
Burn, effectively prevent the gas with foreign flavor that sludge is produced from flying away, while having saved combustion gas energy consumption, more energy-conserving and environment-protective.
