Description
Technical field
The utility model relates to the supporting wind-force load transfer device of boiler desulfurization equipment, is specially a kind of venturi feeder.
Background technology
Because CFBB has premium properties such as high-efficiency low-pollution, therefore be widely used in every field.But the flue gas of discharging from CFBB contains SO
XHigher, cause environmental pollution.SO
2Human beings'health is caused direct harm, the SO in the atmosphere
XForm acid rain with rainfall, in harm humans health, and cause the acidifying of the burn into lake water of building and material, the acidifying and the impoverishment of soil, crops and Forest Growth are slowed down, fish growth is suppressed etc.Along with expanding economy, China SO
XQuantity discharged increases, and ecology environment is faced with huge pressure, and human life and health and living environment have been subjected to serious harm, and the annual direct economic loss that causes because of acid rain has reached about 20,000,000,000 yuan.
Flue gas desulfurization is imperative under the situation of this sternness, and limestone feeding system-dry method in-furnace calcium spraying desulfur technology begins to come out.Because characteristics such as that it has is simple to operate, little, the reduced investment of taking up room are widely used in coal-fired thermal electric generation industry.
The utility model content
The purpose of this utility model is to provide a kind of venturi feeder, solves the problems such as feed of limestone feeding system in the boiler desulfurization equipment.
The technical solution of the utility model is:
A kind of venturi feeder, this loader mainly are provided with inlet point, air intake nozzle, warehouse, adapter bonnet, connector, and the top of warehouse is provided with inlet point, and a side of warehouse is fitted with the air intake nozzle, and the opposite side of warehouse is connected with adapter bonnet by connector.
Be bearing fit between described air intake nozzle and the warehouse.
One end of described air intake nozzle extends in the warehouse, and the other end of air intake nozzle and warehouse end form the control apparatus of air intake nozzle location by regulating bolted connection.
Described adapter bonnet is the exit skirt shape that outwards enlarges, and connector is the exit skirt shape of outwards shrinking.
Described adapter bonnet two ends have flange, and an end of connector connects warehouse by flange, and the other end of connector connects adapter bonnet by flange, and the adapter bonnet other end connects delivery duct by flange.
Described venturi feeder is equipped with and blower fan bonded assembly ventilation inlet in the outside of air intake nozzle.
Described venturi feeder also is provided with the standby ventilation inlet that is communicated with warehouse in a side of warehouse.
The bottom of described warehouse is provided with access opening.
Compared with prior art, the utlity model has following advantage:
1, of the present utility model simple in structure, easy to operate, volume is little, easy installation.
2, wind nozzle location of the present utility model is adjustable, can adapt to various service conditions.Owing to make, install and complicated field condition, often occur since nozzle location forward in the warehouse or lean on after, and material can not normally be carried, nozzle location forward easy putty in warehouse then can not form negative pressure and returns wind to inlet point easily after leaning on.Now increase air intake nozzle location control apparatus, just can make nozzle adjust to the most rational position, make system stability work.
3, the utility model can produce negative pressure when jet size is suitable, favourable mass transport.
4, the utility model is stable, comformability is strong, long service life.
5, the utility model has access opening, can be from access opening unimpeded or other operation.
6, the utility model structurally is provided with air compensation device, breaks down or air feed when not enough at air feed system, in time replenishes pressurized air, and the assurance system normally moves.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1 inlet point; 2 air intake nozzles; 3 ventilation inlets; 4 warehouses; 5 control apparatuss; 6 adapter bonnets; 7 standby ventilation inlets; 8 access opening; 9 connectors.
The specific embodiment
As shown in Figure 1, the utility model venturi feeder mainly comprises control apparatus 5, adapter bonnet 6, standby ventilation inlet 7, access opening 8, connector 9 of inlet point 1, air intake nozzle 2, ventilation inlet 3, warehouse 4, air intake nozzle location etc., and concrete structure is as follows:
The top of warehouse 4 is provided with inlet point 1, and a side of warehouse 4 is fitted with air intake nozzle 2, and the opposite side of warehouse 4 is connected with adapter bonnet 6 by connector 9.
Be bearing fit between air intake nozzle 2 and the warehouse 4, an end of air intake nozzle 2 extends in the warehouse 4, and the other end of air intake nozzle 2 and warehouse 4 ends form the control apparatus 5 of air intake nozzle location by regulating bolted connection; Bolt and nut on the air intake nozzle location control apparatus 5, can change the position of air intake nozzle 2 in warehouse 4, material is fallen in the warehouse from inlet point, and the air intake nozzle location is in the most rational position when the venturi feeder feeding, and mass transport can normal operation.
In addition, be equipped with in the outside of air intake nozzle 2 can with blower fan bonded assembly ventilation inlet 3, also can be provided with the standby ventilation inlet 7 that is communicated with warehouse 4 in a side of warehouse 4, the bottom of warehouse 4 can be provided with access opening 8.
Working process of the present utility model is as follows:
When material enters venturi feeder, material is inlet point 1 charging above warehouse 4, material is fallen air intake nozzle 2 anterior position in the warehouse 4, and when ventilation inlet 3 had the conveying wind of blower fan supply to enter, material is dispelled and quickens to flow forward, blow to adapter bonnet 6, material flows in adapter bonnet 6 through connector 9, when material flows to orifice reducer, just can obtain stable design current velocity, deliver to burner hearth along delivery duct always, finish the conveying task.If faults such as obstruction appear in venturi feeder, can open access opening 8 trouble-shootings.If carry the wind deficiency, can open standby ventilation inlet 7 and in time replenish pressurized air, the assurance system normally moves.When occurring sending not discharging or upwards return wind when serious, the bolt and nut on the scalable air intake nozzle location control apparatus 5 is transferred to correct position with the air intake nozzle, up to normal operation.
The utility model venturi feeder is the end effector of Feed system, mainly is that the material that system provides is treated as loose, suspension, thereby has improved the combustion case of material in the boiler.The utility model carries wind pressure can change the fed distance of material by regulating, owing to carry the storehouse inner chamber to adopt Venturi tube structure, make it under ventilation state, form zone of negative pressure, material is extracted out by air-flow and is mixed, form the material gas mixture that flows fast, the material gas mixture is stable through the variation spouting velocity of one section caliber, and delivers to the target location by transfer line.
