Description
Technical field
It is net more particularly to a kind of waste incineration dry flue gas desulphurization the invention belongs to the technical field of incineration flue gas processing
Makeup is set.
Background technique
Protect environment, energy saving the problem of being every country long-run development overriding concern.The nearest more than ten years, China it is big
Gas management increases year by year, and the air pollutants index general trend that environmental protection administration announces is constantly to decline, but in fact
It is that haze is increasingly severe.City garbage burning has become the main path of developed country's processing house refuse, and house refuse is burnt
Burn flue gas to be made of 2 parts: a part is particulate matter, main comprising pollutants, heavy metal classes pollutants such as organic matter, heavy metals
Based on Pb, Hg and Cd；Another part is gaseous pollutant, with sour gas hydrogen chloride HCl, sulfur dioxide SO2, hydrogen fluoride
HF, nitrogen oxide NOx, based on carbon monoxide CO.
Haze is mainly derived from the flue gas of discharge in air, it is demonstrated experimentally that smoke temperature is higher, easier diffusion, humidity is bigger
Flue gas, be more difficult to spread, also haze more easy to form.
Flue-gas temperature after wet desulphurization is at 30-50 DEG C or so, and humidity is in 100-200g/Nm3(gram/mark side), and
The medial humidity of China's atmosphere is only 9g/Nm3, wet desulphurization smoke evacuation humidity is 10 times or more of atmosphere medial humidity, temperature ratio
Low 80-100 DEG C before desulfurization.It is de- by electrostatic precipitation and milk of lime although thermal effect increases during semi-dry desulfurizing process
After sulphur technique, fine particle obtains deep purifying, but many water is still needed in technical process, in discharge gas water content according to
It is so higher.Old-fashioned dry desulfurizing process lime consumption amount is high, and desulfuration efficiency is minimum, only 30-40%.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of waste incineration dry flue gas desulphurization purification devices, improve de-
Sulphur effect reduces flue gas heat loss and moisture content.
It is net that the technical solution adopted by the present invention to solve the technical problems is to provide a kind of waste incineration dry flue gas desulphurization
Makeup is set, including receives base cleanser feed bin, screw fixed-weight feeder, flour mill, blower and duster, the base cleanser material of receiving
Fang Jialiao mechanism is equipped with inside storehouse, the discharge port for receiving base cleanser feed bin is connect with screw fixed-weight feeder, the spiral
The discharge port of constant feeder is connect with flour mill, and the discharge port of the flour mill is connect by conveyance conduit with duster and institute
It states blower to be set on conveyance conduit, the duster is set in the desulfurization space of incineration flue gas process.
The bulkhead for receiving base cleanser feed bin is configured with anti-frame material blender configured with bottom in feed bin vibrator, storehouse.
The desulfurization space is the connection for burning economizer, air preheater or economizer and air preheater in flue
Socket part.
Downstream in the burning flue positioned at desulfurization space is equipped with bag filter, and the downstream of the bag filter is set
Active charcoal dispenser.
Beneficial effect
The present invention can carry out grinding to the consistent fine particle size of granularity with the coarse granule of sodium base cleanser to desulfurization, from
And biggish specific surface area is obtained, and be directly ejected by way of dusting in incineration flue gas and carry out desulphurization reaction, effectively mention
The uniformity and adequacy of high sodium base cleanser and smoke contacts are conducive to the effect for improving dry desulfurization.Desulfurization process process
It is low to the thermal losses of flue gas, it can reduce subsequent flue gas cost, and dry desulfurization moisture content is low, be conducive to flue gas row
It dissipates after putting to control haze.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the planar structure schematic diagram of flour mill.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
A kind of waste incineration dry flue gas desulphurization purification device as shown in Figure 1, including receive base cleanser feed bin 1, spiral
Constant feeder 2, flour mill 3, blower 4 and duster.
Receiving the bulkhead of base cleanser feed bin 1, bottom, can configured with anti-frame material blender configured with feed bin vibrator, in storehouse
Effectively prevent receiving 1 storehouse internal frame material of base cleanser feed bin the occurrence of.Receive base cleanser feed bin 1 discharge port and spiral quantitative to
Material machine 2 connects, and the discharge port of screw fixed-weight feeder 2 is connect with flour mill 3 (such as Fig. 2).The discharge port of flour mill 3 passes through conveying
Pipeline is connect with duster, and blower 4 is set on conveyance conduit, receives the wind of base cleanser powder for generating to duster conveying
Power.Duster is set in the desulfurization space 9 of incineration flue gas process, and desulfurization space 9 is that economizer, the air in burning flue are pre-
The connection part of hot device or economizer and air preheater.
The downstream for being located at desulfurization space 9 in flue is burned equipped with bag filter 8, the downstream of bag filter 8, which is equipped with, lives
Property charcoal dispenser 5, being equipped with active carbon dispenser 5 is exceeded gas discharge caused by special circumstances in order to prevent, is conducive into one
Step guarantees flue gas from the discharge up to standard of chimney 6.
The purification device is applied in gas flue, and flue gas successively passes through combustion furnace 11 (containing cyclone separator) and electric precipitator
10 reach desulfurization space 9 (economizer, air preheater or connection part) with receive base cleanser dust contact progress desulfurization process,
And cooperate with denitrating flue gas to purify, the flue gas after reaction successively bag filter 8, active carbon dispenser 5, air-introduced machine 7 and chimney 6 to
Outer discharge.
Sodium salt coarse powder and compounding agent (sodium base cleanser) are arrived into required fineness by 3 grinding of super fine grinding machine, acquisition compared with
Big specific surface area according to flue-gas temperature, and calculates according to flue gas total flow and pollutant load the needs of sodium base cleanser
Amount, to control the feed of screw fixed-weight feeder 2, desulfuration efficiency and medicament utilization rate are high.With principle of hydrodynamics, pass through
Duster sprays into sodium base cleanser in exhaust gases passes, quickly reacts with sulfide, the chloride in flue gas, generates minimizing
Stable residue, the residue can be with recycling and reusings.Purified smoke temperature change very little, that is to say, that the heat content of flue gas
It hardly loses, provides good condition for subsequent denitrating technique, need to heat tail flue gas after saving other sulfur removal technologies
Hot cost.And moisture content is low, dissipates after being conducive to flue gas emission to control haze.
