Background technology
Desulfurizer is one of important desulfurization facility of oil plant, the principle of desulfurizer is the diethanol amine doctor treatment that adopts in the wet type desulfurizing method, sulfur-bearing dry gas, liquefied gas in each cover oil refining apparatus are introduced desulfurizing tower, make itself and desulfurization solvent generation chemical reaction at low temperatures, remove sulfur dioxide and carbon dioxide in dry gas, the liquefied gas, the dry gas of output clean from sulfur and liquefied gas.Device mainly partly is made up of dry gas desulfurization, desulfuration of liquefied gas and solvent reclamation etc.Through dry gas and liquefied gas after the desulfurization processing, hydrogen sulfide content can be reduced to below the 50PPm.Because solvent reclamation partial regeneration cat head low pressure gas pressure is low, carries for long distance and brought certain difficulty, and carry the pipeline bore of low pressure gas very big.
Summary of the invention
The purpose of this utility model is for solving low pressure gas length apart from transportation problem, a kind of refinery desulfurizer regenerator low pressure gas conveying equipment is provided, its main points are to increase pressurized equipment on the low pressure gas transfer pipeline, and the high pressure gas of employing soul water stripper is as the power of pressurized equipment, after the low pressure gas pressurization, long distance is carried and can be adopted the less pipeline of bore.
The following technical scheme of the concrete employing of the utility model:
A kind of refinery desulfurizer regenerator low pressure gas conveying equipment comprises regenerator, soul water stripper, and regeneration overhead is provided with the low pressure gas transfer pipeline, and the low pressure gas transfer pipeline is provided with pressure-control valve; Soul water stripper top is provided with the high pressure gas transfer pipeline, it is characterized in that, also is provided with pressurized equipment on described low pressure gas transfer pipeline, and described high pressure gas transfer pipeline is by two branch lines, and one is connected with pressurized equipment, and one is delivered to torch.
Described pressurized equipment comprises high pressure gas import, low pressure gas import, the high pressure gas import is connected with carrier pipe, the carrier pipe front end is provided with nozzle, the low pressure gas import is arranged on the sidewall of pressurized equipment, the pressurized equipment front portion also is provided with mixing chamber, mixes the continuation conveying of pressurization back with low pressure gas from the high pressure gas that nozzle goes out.
For the ease of control, the preferred scheme of the utility model is as follows:
Between pressurized equipment and control valve, be provided with flowmeter on the low pressure gas transfer pipeline, be respectively equipped with temperature control valve, high pressure draught control valve on two branch lines of high pressure gas transfer pipeline.
Compared with prior art, the utlity model has following beneficial effect: 1) after the low pressure gas supercharging, can satisfy the requirement that long distance is carried, but also can adopt the little pipeline of bore, can save great deal of steel; 2) pressurized equipment of the present utility model can produce swabbing action to low pressure gas, and the discharging of low pressure gas is more prone to; 3) flow of the utility model low pressure gas is controlled the amount that high pressure gas is advanced supercharging equipment by control valve, and unnecessary high pressure gas can reach the purpose of control regeneration overhead temperature by the control valve torch of setting fire.

Among the figure, 1 is soul water stripper top temperature control valve, 2 is the regeneration overhead pressure-control valve, and 3 for advancing pressurized equipment high pressure draught control valve, and 4 is soul water stripper, 5 is regenerator, 6 for pressurized equipment, 6-1 are that high pressure gas import, 6-2 are that carrier pipe, 6-3 are that nozzle, 6-4 are the low pressure gas import, and 6-5 is a mixing chamber, and 7 is flowmeter, 8 is the low pressure gas transfer pipeline, and 9 is the high pressure gas transfer pipeline.
The specific embodiment
Embodiment
As shown in Figure 2, a kind of refinery desulfurizer regenerator low pressure gas conveying equipment, comprise regenerator 5, soul water stripper 4, regenerator 5 cats head are provided with low pressure gas transfer pipeline 8, low pressure gas transfer pipeline 8 is provided with regeneration overhead pressure-control valve 2, on transfer pipeline 8, also be provided with pressurized equipment 6, be provided with flowmeter 7 between pressurized equipment 6 and the pressure-control valve 2; Soul water stripper 4 cats head are provided with high pressure gas transfer pipeline 9, and high pressure gas transfer pipeline 9 has two branch lines, and one is connected with pressurized equipment 6, which is provided with high pressure draught control valve 3, and another is delivered to torch, which is provided with tower top temperature control valve 1.
As shown in Figure 3, described pressurized equipment 6 comprises high pressure gas import 6-1, low pressure gas import 6-4, and high pressure gas import 6-1 is connected with carrier pipe 6-2, and carrier pipe 6-2 front end is provided with nozzle 6-3, low pressure gas import 6-4 is arranged on the sidewall of pressurized equipment 6, and the pressurized equipment front portion also is provided with mixing chamber 6-5.
The utility model by regulate, metering low pressure gas flow, can control flow as the high pressure gas of power, simultaneously, the surplus of the high pressure gas torch that reduces internal heat can guarantee the pressure and temperature of soul water stripper 4 like this.
Comparative Examples
As shown in Figure 1, the low pressure gas conveying equipment of prior art is: the low pressure gas of regenerator 5 is by pipeline 8, and soul water stripper 4 is carried by 9 fens two-way of high pressure gas pipeline.Because the gas pressure of low pressure gas is low, the therefore general bigger pipeline of bore that adopts is carried.
