Description

A kind of automobile-used coke oven gas desulfurization device
Technical field
The utility model relates to gas sweetening unit, is specifically related to a kind of desulfurizer of coke(oven)gas Vehicle Fueling Station.
Background technology
Nowadays, China's automobile pollution is growing, and the problem of petroleum resources scarcity appears gradually.Coke(oven)gas is the isolated air of raw coal warp in pit kiln, and after high temperature carbonization, resulting combustible mixture in output coke and tar products, can be used as alternative fuel for cars and use.The stink damp cognition that coke(oven)gas contains causes the problems such as the valve overwear vt. of automotive engine combustion chamber burn into and sealing member damage, also can cause coking problem simultaneously, and the gaseous state SO of combustion of sulfur generation 2be discharged into and in air, change into secondary sulphate particles, its quality is run in 15 to 25 times of the vitriol that of engine direct, causes even more serious topsoil.Therefore, must carry out desulfurizing and purifying processing to coke(oven)gas.Traditional sweetener investment is large, and the sweetening agents such as the ammoniacal liquor using in sweetening process, arsenic have pollution to environment, and can threaten operator's health, are not suitable for promoting the use of in coke(oven)gas Vehicle Fueling Station.
Summary of the invention
The purpose of this utility model is: for the problems referred to above, provide the coke(oven)gas Vehicle Fueling Station sweetener of a kind of economic and reliable and convenient operation.
The technical scheme that the utility model is is: a kind of automobile-used coke oven gas desulfurization device, comprise: coke(oven)gas gas air-intake duct, air intake duct and thionizer, coke(oven)gas gas air-intake duct and air intake duct are communicated with thionizer bottom by three-way interface A, and thionizer top arranges pneumatic outlet.
Thionizer divides two-layer up and down, is filled with respectively thick sweetening agent and desulfurizing agent.
Thionizer bottom is provided with heating unit.
Thionizer top pneumatic outlet is communicated with withdrawing can by Y-tube B, shutoff valve C.
the utility model beneficial effect:
The utility model coke(oven)gas Vehicle Fueling Station desulfurizer is simple to operate, as the gac of sweetening agent main component and ferric oxide, there is activation performance good, desulfurization precision is high, and the advantage of energy cyclic regeneration, be applicable to the desulfurizing and purifying of extensive automobile-used coke(oven)gas, and gac and ferric oxide aboundresources, cheap, can greatly save production cost.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
A kind of automobile-used coke oven gas desulfurization device, coke(oven)gas gas air-intake duct 1 and air intake duct 2 are communicated with thionizer 11 bottoms by three-way interface A3, stopping valve A4 and weather gage 5, thionizer 11 tops arrange pneumatic outlet, thionizer 11 top pneumatic outlets link by stopping valve B12 and Y-tube B13, Y-tube B13 one end is communicated with withdrawing can 15 by shutoff valve C 14, thionizer 11 minutes is two-layer up and down, is filled with respectively thick sweetening agent 7 and desulfurizing agent 10.Thionizer 11 bottoms are provided with heating unit 6.
The coke(oven)gas that contains the impurity such as hydrogen sulfide enters after coke(oven)gas Vehicle Fueling Station, need to enter thionizer and carry out desulfurization processing.Coke(oven)gas is entered by air-intake duct 1, enters thionizer 11 bottoms, slowly by thick sweetening agent 7 three-way interface A3 place and the air mixed that enters from inlet pipe 2.Thick sweetening agent 7 specific surface areas are large, and high adsorption capacity, can accelerate the chemical reaction of desulfurization and have adsorption concurrently while making catalyzer.Under normal temperature state, gaseous state H 2s and airborne O 2under the katalysis of thick sweetening agent, there is oxidizing reaction:
2H 2S + 0 2 → 2H 20 + 2S
The elemental sulfur that reaction generates is adsorbed on thick sweetening agent surface, contained a small amount of organosulfur (COS, CS in coke(oven)gas 2, RSH etc.) thus also can be adsorbed on thick sweetening agent surface reduces total sulphur content in coke(oven)gas.Coke(oven)gas is after the thick preliminary desulfurization of sweetening agent, and the ventilating pit 9 of offering on dividing plate 8 enters upper part of thionizer, reacts as follows with desulfurizing agent 10:
Fe 2O 3·H 2O + 3H 2S → Fe 2S 3 ·H 2O + 3H 20
Fe 2O 3·H 2O + 3H 2S→ 2FeS + S + 4H 2O
Thereby removed the hydrogen sulfide in coke(oven)gas.
Desulfurizing agent 10 desulfurization reach capacity after state, can stop passing into coke(oven)gas, only allow fresh air enter thionizer tower 11, now desulfurizing agent 10 removes the ironic sulfide that generates after hydrogen sulfide and iron sulphide and oxygen and reacts, generate ferric oxide, make desulfurizing agent 11 regeneration:
2 Fe 2S 3·H 20 + 30 2 → 2 Fe 2O 3 + 6S
4FeS· H 2O + 3O 2 + 2H 2O→2Fe 2O 3·H 2O + 4S
When the sulfide of thick sweetening agent 7 absorption reaches capacity, can close stopping valve A4, utilize 6 pairs of isolated air heating to 450 ~ 500 ℃ of thick sweetening agent 7 of heating unit, now can realize thick desulfurizer regeneration, realize recycle.
The sulfurous gas that thick sweetening agent 7 and desulfurizing agent 10 regenerative processes produce enters withdrawing can 15 through pipeline, cooling storage.
