Background technology
When producing the metallurgical coke of blast furnace, the sulfur content in coke is relatively low, so that the hydrogen sulfide in coke-stove gas contains
Amount is not also high, and existing sulfurous gas desulphurization plant is preferable for the desulfuration operations effect of coke-stove gas.But, in production high-sulfur
Hydrogen sulfide content in Jiao Shi, coke-stove gas is more than four times of the hydrogen sulfide content in traditional coke oven coal gas, existing sulfur-bearing
Gas desulphurisation plant can not quickly, efficiently remove the hydrogen sulfide in coke-stove gas in limited space at all, so that nothing
Method meets present environmental requirement.
Semi-dry desulphurization technology is a kind of dry/wet/dry semi-dry desulphurization technology, while having all of wet method and dry method
Course of reaction in the semi-dry desulphurization tower of advantage-i.e. is wet condition, and desulfuration efficiency is high；And byproduct of reaction is dry state,
Accessory substance is either secondary to be all easily handled using still stacking.
The content of the invention
It is a primary object of the present invention to provide a kind of semi-dry desulphurization equipment, to solve sulfurous gas of the prior art
The problem of desulphurization plant desulphurizing ability is poor.
A kind of semi-dry desulphurization equipment, it is characterised in that including reactor, reaction tower support, let out grey EGR, turnover
The reaction tower of gas port composition；The reactor is made up of reactive multilayer room；The reactor is arranged in groups in reaction tower support
Filling limestone particle inside reative cell in portion, the reactor.
The limestone particle being made up of 6 ~ 10mm and 12 ~ 18mm size particles, simultaneous reactions room are filled in each reative cell
Top and side middle and upper part provided with sprinkler tip being sprinkled water to limestone particle surface at regular time and quantity, the covering of the surface of lime stone
A thin layer of moisture film, during flue gas uniform flows each reative cell, forces and is covered with the lime stone of moisture film
Grain contact, and moisture film and lime stone generation corrosion reaction are diffused into immediately.
Further, it is described to let out grey EGR, including electronic let out ash bucket, let out grey baffle plate pond, conveyer, conveyer belt, discharging
Mouth, sub-sieve device；The electronic ash bucket of letting out is arranged on reaction tower support bottom and is connected to reactor bottom, lets out ash bucket bottom and is provided with
Grey baffle plate pond is let out, grey baffle plate pond is let out and is connected with conveyer；The dressing sieve device is arranged on reaction tower cradle top conveyer belt and is connected；Institute
Conveyer is stated to be delivered to material on the sub-sieve device in the discharging opening that reaction tower cradle top is set by conveyer belt.
SO in flue gas2Moved down with the lime stone of reative cell, one layer in limestone surfaces knot of byproduct of reaction gypsum
Duricrust.The reacted tower flue gas outlet of flue gas after purification is discharged into air by chimney, and the pair that limestone particle and surface are covered with
Product is moved down in the presence of conveyer, mutually squeezes mill in folding process between particle, and duricrust comes off.
Further, the air inlet/outlet includes discarded import, purified gas outlet, and is separately positioned on reaction tower support two
End.
Beneficial effect：The equipment has operating efficiency is high, absorbent is easily obtained and utilization rate is high, accessory substance is easily transported can
Secondary utilization, three-phase reaction system, original flue gas system is influenceed it is small, easily update, flexible design, elasticity is high, to unit
Method of operation strong adaptability, concise in technology, it is easy to operate, floor space is small, reliability is high, have certain dust removing effects.
