Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only the present invention's part embodiment, instead of whole embodiments. Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the Biohazard Waste combustion product gases treatment system of the present embodiment comprises: the first air heat exchanger 1, the 2nd air heat exchanger 2, first quench tower 3, dry type extracting tower 4, the 2nd quench tower 5, bag-type dust refining plant and wet type extracting tower 8. First air heat exchanger 1 connects the 2nd air heat exchanger 2,2nd air heat exchanger 2 connects the first quench tower 3, first quench tower 3 connects dry type extracting tower 4, dry type extracting tower 4 connects the 2nd quench tower 5,2nd quench tower 5 connects bag-type dust refining plant, and bag-type dust refining plant connects wet type extracting tower 8. In order to realize quick heat exchange, the gas inlet of the first air heat exchanger 1 and the 2nd air heat exchanger 2 respectively connects a blower fan (connecting the first air heat exchanger 2 as the first blower fan 9 in Fig. 1 connects the first air heat exchanger 1, first blower fan 10). Wet type extracting tower 8 is to the further depickling of the flue gas after dedusting, and the flue gas after depickling is got rid of by chimney.
The Biohazard Waste combustion product gases treatment system of the present embodiment can be cooled to from dual firing chamber's high-temperature flue gas (850 DEG C��1100 DEG C) out less than 200 DEG C (about 180 DEG C) fast by the quench tower of the air heat exchangers of two series connection and two series connection, thus accelerate whole fume treatment flow process, it is to increase processing efficiency. As shown by the arrows in Figure 1, the flue-gas temperature of dual firing chamber's high-temperature flue gas out after two air heat exchangers is usually at 600 DEG C��800 DEG C. In order to the sour gas removed in flue gas, it is provided with dry type extracting tower 4 and wet type extracting tower 8, dry type extracting tower 4 is arranged between the first quench tower 3 and the 2nd quench tower 5, the principle of dry type depickling is quantitatively sprayed into by active lime powder in dry type extracting tower 4, the lime powder making the sour gas in flue gas and specific surface area huge contacts concurrent biochemical reaction, thus reaches depickling object. Can controlling the speed of cooling of the first quench tower 3 so that the temperature after cooling is (as: 500��600 DEG C) below 600 DEG C, namely dry type depickling needs a temperature range. After dry type depickling, 2nd quench tower 5 continues cooling, below flue gas cool-down to 200 DEG C, so both ensures that flue gas avoids 200 DEG C��500 DEG C intervals (temperature range that Dioxins produces), effectively containing Dioxins, the flue gas that can guarantee again to enter follow-up cloth bag bin is constant temperature dry flue gas.
In the present embodiment, first air heat exchanger and the 2nd air heat exchanger air line separately are spiral, thus increase the contact area of freezing air and flue gas, to realize heat exchange more fully, 160 DEG C��250 DEG C are reached after making air heat exchange within the relatively short time, simultaneously by interval, flue-gas temperature heat exchange to 600 DEG C��800 DEG C, for condition is created in follow-up gas cleaning.
The bag-type dust refining plant of the present embodiment comprises: activated carbon adsorber 6 and connected sack cleaner, activated carbon adsorber 6 connects the 2nd quench tower 5, for adsorbing the objectionable impuritiess such as Dioxins a small amount of in flue gas and heavy metal, sack cleaner connects wet type extracting tower 8, for dedusting. Specifically, wet type extracting tower 8 connects sack cleaner by centrifugal blower fan 12, and the flue gas after dedusting is imported wet type extracting tower 8 by centrifugal blower fan 12 fast.
In the present embodiment, sack cleaner comprises two layers of cloth bag storehouse: outer cloth bag bin 71 and internal layer cloth bag bin 72, forms air flow spaces 73 between described outer cloth bag bin 71 and internal layer cloth bag bin 72. Being filled with warm air in air flow spaces 73, make flue-gas temperature in the process of dedusting remain on 130 DEG C��150 DEG C intervals, the flue-gas temperature after wet type depickling can also ensure more than 105 DEG C, thus avoids the phenomenon emitting white cigarette when getting rid of flue gas.
In the present embodiment, the first air heat exchanger 1 and the respective air vout of the 2nd air heat exchanger 2 connect the air flow spaces 73 of sack cleaner. This air, between 160 DEG C��250 DEG C, is filled with air flow spaces 73 and is heated by the flue gas in internal layer cloth bag bin 72, it is achieved that the recycle of the energy, it is to increase the utilization ratio of the energy by the air themperature after two air heat exchanger heat exchanges.
In the present embodiment, in described first quench tower and the 2nd quench tower tower body separately, it is equipped with the automatic single-hole nozzle of a set of water-air two phase flow. Nozzle diameter �� 10mm, material is 316L, the ability of nozzle can meet design requirement, i.e. 500kg��1600kg/h nozzle, water grain diameter after this kind of nozzle atomization is very little, and narrow distribution range (median size 50 ��m, maximum particle diameter is less than 300 ��m), can vaporize completely within the extremely short time. This nozzle makes pressurized air atomize water into very small water smoke, and water smoke is vaporized completely within the time of 1.5 seconds. First quench tower cooling is guaranteed to make flue-gas temperature from 600 DEG C��800 DEG C by flue gas by water and aerosolization, be cooled to more than 550 DEG C less than 600 DEG C. 2nd quench tower is down to less than 200 DEG C from 550 DEG C by water and aerosolization, control flue-gas temperature in 1.5s, such as 160 DEG C��180 DEG C intervals, forms constant temperature dry flue gas.
