2S changes into sulphur hydrogen ammonium salt, changes into elementary sulfur under the oxidation of air, and absorption liquid obtains regeneration), Resorcinol method etc.The various absorption agents of the general employing of wet desulphurization technology are converted into elemental sulfur with the H.S in flue gas or the coal gas, then sulphur-bearing waste solution are carried out desulfurization and produce the sulphur foam.The sulphur foam that desulfurization waste liquor produces in regenerator column enters sulfur melting kettle through foam chute, and through heating, fused sulphur is emitted through steam-jacket pipe from the sulfur melting kettle bottom, and isolated clear liquid is back to reactive tank or is disposed to waste liquid tank by the napex of sulfur melting kettle.
Above-mentioned wet desulfurization system has adopted foam chute, sulfur melting kettle and the waste liquid tank that connects through transfer line, by the fused mode sedimentary fusion sulphur is discharged taking-up, has sweetening effectiveness preferably and realizes the recycle value of sulphur.But there are following serious problems in existing wet desulfurization system in the process of using: at first, owing to from sulfur melting kettle, also can inevitably contain a spot of simple substance sulphur granule in the isolated clear liquid, this simple substance sulphur granule forms precipitation easily in static liquid, existing waste liquid tank is the flat cylinder bodily form, its bottom sidewall is provided with waste liquid outlet, and sedimentary elemental sulfur causes the obstruction of waste liquid tank waste liquid outlet easily; Secondly, the potential safety hazard that the person is existed when preventing molten sulphur from the fusion sulphur discharged of sulfur melting kettle bottom, existing fusion sulphur delivery pipe all adopts 90 ° of chuck bend pipes, this the easiest obstruction that causes fusion sulphur delivery pipe in bend pipe position, need to stop work and handle, this so cause the obstruction of part pipeline, influence the normal use of whole wet desulfurization system.Provide processing for the equipment claimed of occur stopping up, this has caused gas quality not up to standard for a long time, and adopts artificial regularly stir or when the pump recoil is dredged in the hole, and construction environment badly and DeGrain.And long-standing deposition sulphur has stronger corrodibility, cause easily pipeline steam race, emit, leak, diffuse big.
The utility model content:
The purpose of this utility model provides a kind of multiple-grooved connected vessels type desulfurizer, it can thoroughly solve sulfur melting kettle, waste liquid tank blockage problem, guarantee the normal operation continuously of wet desulfurization system, thereby guarantee the wet desulfurization system of gas quality, solved the blockage problem of pipeline and key part in the existing wet desulfurization system.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of intake pipeline 1, stirring mechanism 2, foam chute 3, transferpump 4, sulfur melting kettle 5, steam jacket short straight tube 6, waste outlet 7, waste liquid tank 8, waste liquid outlet 9 and waste liquid car 10; Foam chute 3 tops are connected with intake pipeline 1, foam chute is provided with stirring mechanism 2 in 3 tops, foam chute 3 bottoms are connected with sulfur melting kettle 5 by transferpump 4, sulfur melting kettle 5 bottoms are provided with steam jacket short straight tube 6, sulfur melting kettle 5 tops are provided with waste outlet 7, and waste outlet 7 is connected with waste liquid tank 8, and waste liquid tank is provided with stirring mechanism 2 in 8 tops, waste liquid tank 8 bottoms are provided with waste liquid outlet 9, and waste liquid outlet 9 is arranged with waste liquid car 10.
Described foam chute 3 bottoms are the conical bottom structure; Described stirring mechanism 2 upper ends are provided with the stirring drive-motor; Described steam jacket short straight tube 6 is for erectting vertical pipe; Described waste liquid outlet 9 is for erectting vertical pipe.
Described sulfur melting kettle 5 is discharged into waste liquid flow 〉=1.5 ton/hour of waste liquid tank 8, and the temperature of waste liquid is controlled at 60～90 ℃.
5 ones molten sulphur temperature is 125～135 ℃ at the bottom of the described sulfur melting kettle, and still is pressed≤3.5～4Kg, and the molten sulphur time is no less than 2 hours.
Liquid level in the described waste liquid tank 8 is controlled in the 1.8m, and the internal diameter of the setting vertical pipe of sulfur melting kettle 5 is 20～30m.
The utility model is started with at the susceptible to plugging basic reason of each equipment in the wet desulfurization system, adopt short and unresisted setting vertical pipe that the molten sulphur in the sulfur melting kettle is carried out the smoothness discharging, make this molten sulphur emissions Guan Buhui blockage phenomenon, also avoid heating method to dredge that existing steam consumption is big, long-time heating can make and produce the secondary salt crystallization in the delivery pipe, caused the problem of more difficult cleaning tamper.Go into waste liquid tank through the discharging of waste liquid after the sulfur melting kettle processing, the whipping appts that is provided with in the waste liquid tank carries out continuously stirring to the waste liquid in the waste liquid tank, and elemental sulfur and waste liquid flow at the waste liquid tank internal rotation, and elemental sulfur is difficult for precipitating.The waste liquid tank of conical bottom structure can effectively be avoided the deposition of elemental sulfur in the waste liquid tank bottom simultaneously.
The utility model can be good at being fit to this wet desulfurization system, and satisfy the processing requirement of various wet desulphurizations, produce stable, guaranteed the operation continuity of whole wet desulfurization system, continuous feed liquor in sulfur melting kettle and the waste liquid tank, stirring mechanism continuously and smoothly in the continuous blow-down, waste liquid tank stirs, and regular discharge melts sulphur.The successive sulfur removal technology can be avoided the precipitation of elemental sulfur in each parts and the pipeline, when the excellent operation environment is provided, solve the blockage problem of sulfur melting kettle, waste liquid tank and pipeline completely, thereby also well avoided the thionizer in the wet desulfurization system and the obstruction of foam chute.
The beneficial effects of the utility model are that each component design of this wet desulfurization system is reasonable, have effectively eliminated the molten stream still that elemental sulfur causes and the obstruction of waste liquid tank, can guarantee the normal continuous operation of pipeline and each sweetener, and keep the normal quality of coal gas.Operational condition gentleness of the present utility model can meet the requirement of desulphurization system, guarantees the ability of working continuously of wet desulfurization system, alleviates the operating environment and the intensity of wet desulfurization system.
