Description

With the flue gas desulfurization deacidification equipment impacting throwing device
Technical field
The utility model relates to field of Environment Protection, specifically a kind of flue gas desulfurization deacidification equipment for garbage incinerating power plant.
Background technology
When garbage incinerating power plant carries out flue gas desulfurization depickling process, be use frequency conversion auger to send into after mixing in reaction tower, with the SO in flue gas with the returning charge ash of returning charge auger by the lime with returning charge storehouse that start feed bin 2discharge again after fully reacting Deng sour gas.
But changeable as the house refuse complicated component of fuel, in combustion process, the instantaneous generation large quantity of exhaust gas of meeting, owing to cannot promote lime feeding amount immediately, is therefore difficult to remove the harmful components in flue gas in time, causes discharge to exceed standard.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, and provide the flue gas desulfurization deacidification equipment with impacting throwing device, this equipment should be able to promote lime feeding amount in time effectively to remove the pernicious gas in flue gas.
The technical solution of the utility model is: with impacting the flue gas desulfurization deacidification equipment of throwing device, comprise for the treatment of flue gas and the reaction tower in exhaust outlet access returning charge storehouse, for deposit lime and successively by frequency conversion lime auger and returning charge auger to the startup feed bin of reaction tower feeding and for depositing returning charge ash and by the returning charge storehouse of returning charge auger to reaction tower feeding; It is characterized in that:
The impact that this equipment is also provided with for promoting lime feeding amount adds throwing device; Described impact adds throws device and comprises being arranged in and to start between feed bin and returning charge auger and to install valvular screw auger, start feed bin also successively by screw auger and returning charge auger to reaction tower feeding;
Described valve is pneumatic gate valve and is arranged on the discharging opening of screw auger.
First discharging opening of described startup feed bin connects the charging aperture of frequency conversion lime auger and the first charging aperture of the discharging opening (42) of frequency conversion lime auger connection returning charge auger.
The discharging opening in described returning charge storehouse connects the second charging aperture of returning charge auger.
Second discharging opening of described startup feed bin connects the charging aperture of screw auger and the 3rd charging aperture of the discharging opening of screw auger connection returning charge auger.
In described returning charge auger, the 3rd charging aperture is arranged on the left of the first charging aperture.
The beneficial effects of the utility model are:
The utility model is when nominal situation state, and impact adds throwing device and quits work (valve closing); And start impact when running into emergency case immediately and add throwing device, thus promote the feeding amount of lime in time, effectively eliminate the SO in flue gas 2deng sour gas, ensure emission compliance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, with impacting the flue gas desulfurization deacidification equipment of throwing device, comprise for the treatment of flue gas reaction tower 1, for deposit lime startup feed bin 2, for depositing the returning charge storehouse 3 of returning charge ash, frequency conversion lime auger 4 and returning charge auger 5.
The exhaust outlet 12 of described reaction tower accesses in returning charge storehouse, and the flue gas produced of burning away the refuse passes into (shown in arrow A) from the air inlet 11 bottom reaction tower, enters returning charge storehouse and discharge (shown in arrow B) from top, returning charge storehouse through exhaust outlet.
Described startup feed bin successively by frequency conversion lime auger and returning charge auger to reaction tower feeding; The first discharging opening 21 starting feed bin connects the charging aperture 41 of frequency conversion lime auger, the discharging opening 42 of frequency conversion lime auger connects the first charging aperture 51 of returning charge auger, the discharging opening 54 of returning charge auger connects reaction tower, and the discharging opening 31 in returning charge storehouse connects the second charging aperture 52 of returning charge auger.In returning charge auger, the second charging aperture 52 is positioned at the left side of the first charging aperture 51.
Above structure is same as the prior art.And original " consumer waste incineration Environmental capacity standard " (GB18485-2001) requires SO 2concentration of emission hourly value is less than 260mg/Nm 3, existing equipment can meet emission request.But new " consumer waste incineration Environmental capacity standard " (GB18485-2014) requires SO 2concentration of emission hourly value is less than 100mg/Nm 3(annual average is less than 80mg/Nm 3), the concentration of emission hourly value of HCL is less than 60mg/Nm 3(annual average is less than 50mg/Nm 3), existing equipment cannot meet emission request.
Improvements of the present utility model are:
The utility model is provided with the impact throwing device for promoting lime feeding amount; This impact throwing device comprises the screw auger 6 being provided with valve 63; Described screw auger 6 is arranged in and starts between feed bin and returning charge auger, start feed bin also successively by screw auger and returning charge auger to reaction tower feeding.
Second discharging opening 22 of described startup feed bin connects the charging aperture 61 of screw auger, and the discharging opening 62 of screw auger connects the 3rd charging aperture 53 of returning charge auger.Start in feed bin, the second discharging opening 22 is positioned at below the first discharging opening 21.In returning charge auger, the 3rd charging aperture 53 is positioned at the left side of the second charging aperture 52.Described valve is pneumatic gate valve and is arranged on the discharging opening of screw auger, and the conveying capacity of screw auger meets 10t/h.
In normal operating conditions, impact throwing device and quit work (screw auger does not work and valve closing); SO in the middle of flue gas 2when rolling up suddenly Deng sour gas, impact throwing device and start (screw auger work and valve open), impact and add deacidification agent (Ca (OH) 2), the SO in flue gas 2normal level can be dropped to immediately Deng sour gas index, then stop impacting throwing device.Increase after impacting throwing device, all the time can by SO 2concentration of emission hourly value controls at 100mg/Nm 3below, annual average controls at 80mg/Nm 3below, the concentration of emission hourly value of HCL controls at 60mg/Nm 3below, annual average controls at 50mg/Nm 3below.
