Description
Technical field:
The utility model relates to the environmental unit that is used for industry flue gas desulfurizations such as electric power, building materials, metallurgy, chemical industry, is specifically related to a kind of novel semi-dry flue gas desulfurization device.
Background technology:
In existing flue gas desulfurization technique, the wet method separation of flow is be most widely used at present a kind of.Yet huge because of its pulping equipment, floor space exists, and perishable, the fouling of pipe-line equipment has contaminated wastewater and flue gas reheat system etc., makes its investment and operating cost all higher, makes wet method glue sulphur be subjected to certain restriction in the application of some occasion.Compare with wet desulphurization, semi-dry process flue gas desulphurization is because system is simple, investment and operating cost are lower, and desulfurization product becomes advantage such as dry powder shape not to be applicable to Pump for Medium and Small Power Generating Set flue gas desulfurization.
Traditional semidry method flue gas separation of flow method mainly contains two kinds: a kind of is the flue gas desulfurizations of direct injection slurries, is widely used in its flue gas in power station boiler desulfurization at home and abroad.In the part that in actual motion, also obviously comes with some shortcomings: 1, because the solubility of lime in water is low, must make lime milkiness slurries, its serum producing system is complicated and huge 2, higher to the atomizer quality requirement, often factors such as even and granularity is inhomogeneous because of the density unevenness of lime slurry cause atomization badness, and can cause the obstruction and the wearing and tearing of atomizer.Be obstruction, the wearing and tearing that prevent atomizer, must adopt the high speed rotary-atomizing nozzle or the novel double fluid atomization nozzle of special material.3, lime slurry atomizing difficulty, the atomized drop particle diameter is big, and desulphurization reaction speed is low, thereby causes the absorption tower bulky, influences the further reduction and the application in existing power plant transforms of desulphurization plant cost of investment.Another kind is flue humidification activation desulfurization LIFAC.Also there are some problems in its flue humidification activation separation of flow part: 1, for pulverized-coal fired boiler, because China's steam coal ashes mass fraction is higher, generally more than 20%, the desulfurizing agent mass ratio of flying dust and adding in the flue gas is more than 10 times, when spraying identical atomized water humidification activation desulfurizing agent, owing to exist a large amount of flying dusts and desulfurizing agent " to rob water ", promptly a large amount of water droplets are absorbed by flying dust, the actual water calcium of desulfurizing agent mol ratio is very low, and the desulfurizing agent low-temp reaction is not high.2, because of its whole flue gases pass through activated reactor, sorbent particle and water smoke are diluted greatly by flue gas, and its collisional activation efficient is lower, only is about 25%.It causes activated reactor bulky in above reason, and desulfuration efficiency is difficult for improving.
The utility model content:
The purpose of this utility model provides a kind of novel semi-dry flue gas desulfurization device, it avoided flying dust and desulfurizing agent " rob water " and water smoke and desulfurizing agent by flue gas dilution, the collisional activation efficient of sorbent particle and water droplets and the activity of desulfurizing agent have been improved greatly, can increase substantially desulfuration efficiency and sorbent utilization, reduce the volume of desulfurizer to greatest extent.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of smoke inlet, forward type atomizing generator, two-fluid spray nozzle, desulfurization duct, gas outlet and ash bucket, forward type atomizing generator front side is provided with smoke inlet, forward type atomizing generator upper end is provided with two-fluid spray nozzle, forward type atomizing generator is connected with desulfurization duct, the desulfurization duct rear side is provided with the gas outlet, and the lower end of forward type atomizing generator and desulfurization duct is provided with ash bucket.
Described smoke inlet adopts the reducing design.
Described desulfurization duct adopts the design of S shape.
Operation principle of the present utility model is: the vaporific generator of a forward type multithread body is set, a small amount of flue gas or air carry tiny solid-state sorbent particle and enter wherein by air distributor, in the vaporific generator of multithread body, water droplet and sorbent particle collisional activation under higher granular mass mark of two-fluid spray nozzle atomizing, the formation slurry drips, thereby finishes the online preparation of vaporific desulfurizing agent; Then, the vaporific desulfurizing agent of the wet type of online preparation continuously evenly will is mixed in the flue gas of boiler flue with certain time of staying or reactor, finishes the desulfurization rapidly reaction in flue.Compare with the flue gas desulfurization of direct injection slurries, this method can fundamentally be avoided having removed complicated serum producing system simultaneously from owing to spray problems such as atomizer obstruction that lime slurry causes and wearing and tearing, reactor be huge.
Compare with humidification activations such as LIFAC, the utility model because of avoided flying dust and desulfurizing agent and " robbed water " and water smoke and desulfurizing agent by flue gas dilution, the collisional activation efficient of sorbent particle and water droplets and the activity of desulfurizing agent have been improved greatly, can increase substantially desulfuration efficiency and sorbent utilization, reduce the volume of desulfurizer to greatest extent.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, this specific embodiment is by the following technical solutions: it is made up of smoke inlet 1, forward type atomizing generator 2, two-fluid spray nozzle 4, desulfurization duct 5, gas outlet 6 and ash bucket 7, forward type atomizing generator 2 front sides are provided with smoke inlet 1, forward type atomizing generator 2 upper ends are provided with two-fluid spray nozzle 4, forward type atomizing generator 2 is connected with desulfurization duct 5, desulfurization duct 5 rear sides are provided with gas outlet 6, and the lower end of forward type atomizing generator 2 and desulfurization duct 5 is provided with ash bucket 7.
