Utility model content
The purpose of this utility model is to solve above-mentioned technology, and there is provided a kind of succinct, Low investment, high performance desulfurization system
System, floor space is small, the semidry process desulfurizer provided easy access to.
Above-mentioned purpose of the present utility model is realized by following technical scheme：A kind of semidry process desulfurizer, including
Electric cleaner, flue reaction tube and sack cleaner, described electric cleaner left end are provided with the first smoke inlet, and described electricity is removed
Dirt device right-hand member connects with smoke tube, and described smoke tube connects with flue reaction tube, and described flue reaction tube is with mixing
Humidifier connects, and is provided with digester above the hybrid humidifier, and the left end of described sack cleaner and described flue are anti-
Should pipe connect, described sack cleaner right-hand member connects with flue gas delivery line, the described flue gas delivery line other end and chimney phase
Connect, described sack cleaner bottom connects with efferent duct, the described efferent duct other end connects with dry ash storehouse, described dry ash
Provided with dry powder outlet below storehouse.
It is preferred that, described smoke tube is provided with branch pipe, the described branch pipe other end and described flue gas delivery line phase
Connection.
It is preferred that, described branch pipe is provided with switch valve.
The beneficial effects of the utility model are：Slurrying and spraying system are eliminated, the digestion and circulation for carrying out calcium oxide increase
Wet integrated design, this not only overcome occur during independent digestion leak out, plugging the problems such as, and can using digest when produce
Steam, add the relative humidity of flue gas, it is favourable to desulfurization, while overcome that common semidry method absorption tower is likely to occur is viscous
Wall phenomenon, carries out Desulphurization and repeatedly circulates, circulating ratio may be up to 50 times, the utilization rate of desulfurizing agent is brought up to 95%, overcomes
The problem of other semidry process sorbent utilization notices, this programme desulfuration efficiency is high, and desulfurization is made with 90% calcium oxide
Agent, as Ca/s=1.1mol/mol, it is ensured that desulfurization degree is more than 80%；As Ca/s=1.2~1.3mol/mol, desulfurization degree can
Up to more than 90%.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Smoke inlet 1, smoke tube 2, electric cleaner 3, digester 4, hybrid humidifier 5, branch pipe 6, switch valve 7,

Embodiment
As shown in figure 1, a kind of semidry process desulfurizer, including electric cleaner 3, flue reaction tube 8 and sack cleaner 9,
The described left end of electric cleaner 3 is provided with smoke inlet 1, and the described right-hand member of electric cleaner 3 connects with smoke tube 2, described cigarette
Airway 2 connects with flue reaction tube 8, and described flue reaction tube 8 connects with hybrid humidifier 5, on the hybrid humidifier 5
Side is provided with digester 4, and the left end of described sack cleaner 9 connects with described flue reaction tube 8, described sack cleaner
9 right-hand members connect with flue gas delivery line 10, and the described other end of flue gas delivery line 10 connects with chimney 11, described sack cleaner
9 lower ends connect with efferent duct 14, and the described other end of efferent duct 14 connects with dry ash storehouse 12, and the described lower section of dry ash storehouse 12 is provided with
Dry powder outlet 13.
Described smoke tube is provided with branch pipe, and the described other end of branch pipe 6 is connected with described flue gas delivery line 10,
Described branch pipe 6 is provided with switch valve 7.
The conventional desulfurizing agent of the grey circulation desulfurization technology of humidification is CaO, and CaO adds water in a digester specially designed to disappear
Ca (OH) 2 is melted into, after by hybrid humidifier, the moisture of combination ash is then introduced into flue reaction by 2% increase by 5%
Pipe reacts with the SO2 in flue gas, generates calcium sulfite, and make final product be dry powder-shaped.
The utility model eliminates slurrying and spraying system, carries out the digestion and circulation humidification integrated design of calcium oxide,
This not only overcome occur during independent digestion leak out, plugging the problems such as, and can be added using the steam that produces when digesting
The relative humidity of flue gas, it is favourable to desulfurization, while overcoming the wall sticking phenomenon that common semidry method absorption tower is likely to occur, carry out de-
Sulphur ash repeatedly circulation, circulating ratio may be up to 50 times, the utilization rate of desulfurizing agent is brought up to 95%, overcome other semidry method works
The problem of skill sorbent utilization notice, this programme desulfuration efficiency is high, makees desulfurizing agent with 90% calcium oxide, works as Ca/s=
During 1.1mol/mol, it is ensured that desulfurization degree is more than 80%, and as Ca/s=1.2~1.3mol/mol, desulfurization degree is up to more than 90%.
Technical principle of the present utility model is described above in association with specific embodiment, these descriptions are intended merely to explain this reality
With new principle, and the limitation to the utility model protection domain can not be construed in any way, based on explanation herein,
