Abstract
The present invention provides a kind of processing systems of domestic sludge incineration flue gas, can solve the high technical problem of subsequent flying dust cost of disposal.A kind of processing system of domestic sludge incineration flue gas, it is characterized by comprising sequentially connected chilling tower, extracting tower, the first bag filter and the second bag filter, activated charcoal adding apparatus is connected on the pipeline that the first bag filter and the second bag filter are connected.When the system handles flue gas, detection is sampled by the flying dust collected to the first bag filter, if general solid waste, then solid waste is disposed by, if dangerous waste, then merges disposition with the dangerous waste containing active carbon of the second bag filter, dangerous waste total amount can be effectively reduced, cost of disposal is reduced.
Description
Technical field
The present invention relates to sludge incineration technical fields, and in particular to a kind of processing system of domestic sludge incineration flue gas.
Background technique
The processing system of existing domestic sludge incineration flue gas is general are as follows: cyclone dust collectors → neutralizing tower → adds powder work
Property charcoal → sack cleaner → wet type neutralizing tower (alkali liquid washing is reserved spare), fume treatment it is up to standard after after pass through smoke stack emission.
Since flying dust caused by system processing mixes active charcoal, according to " National Hazard waste register (2016) ", " solid waste
The waste active carbon that exhaust-gas treatment generates in burning process is dangerous waste (dangerous waste code: 772-005-18) ", so flying dust need to be according to danger
Useless disposition, and dangerous waste cost of disposal is higher.
Summary of the invention
The present invention provides a kind of processing systems of domestic sludge incineration flue gas, and it is high to can solve subsequent flying dust cost of disposal
The technical issues of.
Its technical solution is a kind of such, processing system of domestic sludge incineration flue gas, it is characterised in that: including successively
Chilling tower, extracting tower, the first bag filter and the second bag filter of connection, first bag filter and described
Activated charcoal adding apparatus is connected on the connected pipeline of two bag filters.
Further, the outlet side of the extracting tower is connect by branch pipe with the inlet end of second bag filter,
The branch pipe, the inlet end of first bag filter and outlet side are separately installed with valve.
Further, the unloading valve of first bag filter is connected with the first flying dust storage element, second cloth
The unloading valve of bag dust collector is connected with the second flying dust storage element, and the first flying dust storage element is stored up higher than second flying dust
Memory cell, the bottom surface of the first flying dust storage element tilt down setting, the bottom surface lower of the first flying dust storage element
One end is connected by ash-unloading tube road, valve with the second flying dust storage element, and the bottom surface of the first flying dust storage element connects
It is connected to vibrator.
Further, first bag filter is equipped with two or more, and the inlet end of each first bag filter goes out
Gas end is arranged in parallel and is respectively equipped with valve, and the unloading valve of each first bag filter is connected separately with the storage of the first flying dust
Memory cell；Second bag filter is equipped with two or more, and the inlet end of each second bag filter, the equal parallel connection in outlet side are set
Valve is set and is respectively equipped with, the unloading valve of each second bag filter is connected separately with the second flying dust storage element.
Further, the extracting tower is semidry method extracting tower.
High-temperature flue gas is quenched by chilling tower, and then skips the temperature of dioxin easily generated by processing system of the invention
Area reduces the generation of dioxin, by the sour gas in extracting tower and in removal flue gas, collects to the first bag filter
Flying dust is sampled detection, if general solid waste, then solid waste is disposed by, if dangerous waste, then with the second bag-type dust
The dangerous waste containing active carbon of device merges disposition, can effectively reduce dangerous waste total amount, reduces cost of disposal.
Detailed description of the invention
Fig. 1 is the schematic diagram of processing system of the invention.
Specific embodiment
As shown in Figure 1, a kind of processing system of domestic sludge incineration flue gas, including sequentially connected chilling tower 1, extracting tower
2, the first bag filter 3 and the second bag filter 4, the pipeline that the first bag filter 3 is connected with the second bag filter 4
On be connected with activated charcoal adding apparatus 5, extracting tower 2 is semidry method extracting tower 2.
The outlet side of extracting tower is connect by branch pipe 6 with the inlet end of the second bag filter 4, and branch pipe 6, the first cloth bag remove
The inlet end of dirt device 3 and outlet side are separately installed with valve, when the flying dust sampling Detection that the first bag filter 3 is collected is dangerous waste
Afterwards, the valve of the inlet end of the first bag filter 3 can be closed, opens the valve of branch pipe 6, and then flue gas directly passes through branch pipe 6
It is conveyed to the second bag filter 4, while adding activated carbon adsorption harmful substance.
The unloading valve of first bag filter 3 is connected with the first flying dust storage element 7, and the second bag filter 4 unloads ash
Valve is connected with the second flying dust storage element 8, and the first flying dust storage element 7 is higher than the second flying dust storage element 8, the storage of the first flying dust
The bottom surface of unit 7 tilts down setting, bottom surface lower one end of the first flying dust storage element 7 by ash-unloading tube road 10, valve with
Second flying dust storage element 8 is connected, and the bottom surface of the first flying dust storage element 7 is connected with vibrator 9, when the first bag filter 3
The flying dust sampling Detection of collection is can open the valve on vibrator 9 and ash-unloading tube road 10 after dangerous waste, so that the first flying dust stores
Fly ash carry in unit 7 enters the second flying dust storage element 8, collects convenient for the merging of dangerous waste flying dust, while avoiding generally solid
The mixing of useless and dangerous waste, and the first flying dust storage element 7, the setting of 8 difference in height of the second flying dust storage element and the storage of the first flying dust
Cut oblique setting in the bottom surface of memory cell 7, it can be ensured that the conveying and discharge of flying dust.
