Description
Technical field
The utility model is related to the improvement of solid waste burning disposal center depickling medicament grinding center conveyor, and in particular to
A kind of improvement of solid waste burning disposal center dry-process deacidification medicament grinding conveying device.
Background technology
At present after danger wastes burning disposal, flue gas passes through " chilling+dry-process deacidification+activated carbon through UTILIZATION OF VESIDUAL HEAT IN
The gas cleaning processing of absorption+bag filter+wet method depickling+flue gas reheat+activated coke absorption ", final flue gas meet discharge
It is required that it is discharged again under the action of air-introduced machine by chimney.
Dry method+wet method two level deacidifying process has been selected in the removing of acid gas in flue gas.Dry-process deacidification technical process is simple,
Without sewage, acidless treatment problem, but using calcium hydroxide as depickling medicament, deacidification efficiency is low.Wet method depickling deacidification efficiency is high, but
Waste water can be generated and cause secondary pollution.Although wet method depickling employs Dual alkali and mating chamber filter press takes off recirculated water
Salt treatment, reduces the discharge of the brine waste of part, but still needs to waste discharge at regular time and quantity.
With the continuous promotion of environmental legislation, the sour gas quantitative requirement of exhaust gas is discharged increasingly to dangerous waste incineration disposal
It is high；With reference to external exhaust-gas treatment experience, people constantly recognize to be had using sodium bicarbonate as depickling medicament dry-process deacidification technique
There is an impayable advantage, but the grinding of dosing process and sodium bicarbonate conveying requires very strict, currently used equipment is all
It is difficult to perfect.
Utility model content
The purpose of this utility model is that the defects of for the prior art and deficiency, provide a kind of dry-process deacidification medicament grinding
Conveying device, it makes whole set process fixed equipment cost of investment low；It is readily cleaned and safeguards, operation and maintenance cost is low.Maximum
Advantage be advantage be grinding after sodium acid carbonate do not transported by wind turbine, it is entirely avoided the fouling problem of wind turbine.The consumption of wind turbine
Electricity also decreases, and makes operating cost lower.
To achieve the above object, the utility model is using following technical scheme：It include feed bin 1, screw feeder 2,
Feed auger valve 3, wind turbine 4, pulverizer 5, muffler 6, the bottom discharge mouth of feed bin 1 connect charging spiral shell by screw feeder 2
Stopcock 3, the lower end of feed auger valve 3 are connected on air hose 7, are connected at the air inlet of air hose 7 on the air outlet of wind turbine 4, air hose 7
Air outlet be connected on pulverizer 5, the discharge port of pulverizer 5 connection flue.
Muffler 6 is provided on the wind turbine 4.
The screw feeder 2 uses volume type single screw rod feeder.
The utility model is directed to the grinding system of the sodium bicarbonate size controlling in flue gas dry desulfurizing technique.Sodium acid carbonate from
Storage tank supplies graded mill surely by a screw conveyor, and sodium acid carbonate dosage is by screw conveyor frequency control, in spiral
Rotary valve must be installed between conveyer and grading mill, for isolating air-flow, in order to avoid the quantitative feeding of airflow influence screw conveyor.
Assembling is pressed into grinding machine before grading mill, by air.The advantages of this operating mode is that the sodium acid carbonate after grinding is obstructed
Cross wind turbine transport, it is entirely avoided the fouling problem of wind turbine.In addition, the power consumption of wind turbine also decreases, make operating cost lower.
Due to transport and storage, sodium acid carbonate raw material is typically coarse granule (d50 values are about 200 microns).As wanted
Reach higher reactivity, adsorbent there must be larger specific surface area.Therefore before flue is injected, sodium acid carbonate must
Certain fineness must be ground to.For example, to remove SO2 sodium acid carbonates fineness must reach d90<20μm.And it removes HCl and only requires d90<
35μm。
In order to keep required sodium acid carbonate fineness in long period operation, impact grinding of the generally use with grader is also known as
Grading mill, after grinding, adsorbent, which is transported with gas mode of movement and passes through multiple nozzles, is passed directly into flue, to ensure it
It is uniformly dispersed in pipeline.The design of this complete equipment is simple and durable, compared with other gas cleaning modes, its investment and operation into
This is relatively low.
The utility model so that whole set process fixed equipment cost of investment is low；It is readily cleaned and safeguards, operation and maintenance cost
It is low.Biggest advantage be advantage be grinding after sodium acid carbonate do not transported by wind turbine, it is entirely avoided the fouling problem of wind turbine.
The power consumption of wind turbine also decreases, and makes operating cost lower.
