Description
Technical field
The utility model belongs to lightweight oil processing treatment technical field, is specifically related to the equipment of a kind of lightweight oil desulfurization, deodorization and decolouring.
Background technology
At present, the production technique of lightweight oil desulfurization is broadly divided into methods such as hydrofining, special-purpose catalyst sweetener and membrane technique.Hydrofining and the investment of special-purpose catalyst sweetener are expensive, and mechanical discipline is strong, and are not suitable for the most of medium-sized and small enterprises uses of China.
Summary of the invention
The lightweight oil that the utility model exceeds standard at existing sulphur content provides a kind of less investment, sweetener that efficient is high, described equipment is also referred to as lightweight oil high-efficiency desulfurization device, the equipment that provides by the utility model, can the effective elimination sulphur content exceed standard mercaptan sulfur, the hydrogen sulfide of lightweight oil remove sulphur stink, the variable color colloid of lightweight oil.
Principle of work of the present utility model: utilize the principle be combined into of precipitation apparatus and static mixer,, thereby reach the effect that removes lightweight oil mercaptan with the supporting use of sweetening agent.
Described a kind of lightweight oil sweetener mainly comprises upper cover, base and tank body, and described tank body is a tubular.The top of tank body and bottom are sealed by upper cover and base respectively, the tank interior space is filled sweetening agent and is provided with horizontal baffle, the tank body of described horizontal baffle below is provided with feed-pipe and rinse mouth, and the tank body above the horizontal baffle is provided with discharge nozzle and hand hole; Wherein discharge nozzle is connected with water washing tank.
Described horizontal baffle is divided into U type passage, at least 5 of dividing plate quantity with sweetener lower part.
The outside heat-insulation and heat-preservation material that coats of described tank body.
The liquid level of sweetening agent is higher than the horizontal baffle height in the described tank body, is lower than the height of discharge nozzle.
On described upper cover, also be provided with liquidometer.
Be transported in the lightweight oil sweetener provided by the invention by ram pump or hydro-pump through pretreated lightweight oil, under the effect of sweetening agent, just can reach the effect of desulfurization, deodorization, decolouring.
The utility model at medium and small refinery and without the oil product of hydrogenation device for treatment contain the mercaptan height, smell is smelly, colloid is defective, the situation of oil stability difference, utilize problems such as proprietary equipment solution lightweight oil sulphur content height, smell are smelly, oil stability difference, have low cost, high-efficiency characteristics, have very high economic worth and practicality.
The lightweight oil sweetener that the utility model provides, it is few to reach facility investment, and sweetening agent utilising efficiency height, oil product treatment effect wait many-sided advantage well.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
The invention provides a kind of lightweight oil sweetener, as shown in Figure 1, described lightweight oil sweetener mainly comprises upper cover 1, base 2 and tank body 3, the described tank body 3 outside heat-insulation and heat-preservation materials (generally adopting lagging materials such as insulating cotton) that coat, tank body 3 is a tubular, and the top of tank body 3 and bottom are sealed by upper cover 1 and base 2 respectively.Side at tank body 3 is provided with feed-pipe 4 near base position, and feed-pipe 4 stretches into tank body 3 inside, and the height of feed-pipe 4 is lower than the height of horizontal baffle 9.Described tank body 3 tops are provided with discharge nozzle 5 and hand hole 6, and wherein discharge nozzle 5 is connected with the water washing tank opening for feed, are used for the lightweight oil that removes mercaptan sulfur, hydrogen sulfide in the tank body 3 is further removed alkalescence and impurity through washing; Described hand hole 6 is used for turnaround of unit and adds sweetening agent initial the time.Side bottom at described tank body 3 is provided with a rinse mouth 7, is used for overhaul of the equipments and regularly discharges residual night, and the height of described rinse mouth 7 is lower than the height of horizontal baffle 9.Tank body 3 internal upper parts of lightweight oil high-efficiency desulfurization equipment are settled layer, and the bottom increases sweetening agent and lightweight oil contact area and time for to cut into the U type circulation space by horizontal baffle 9.
Fill sweetening agent in the tank body 3, the liquid level of sweetening agent still is lower than the height of discharge nozzle 5 more than or equal to the height that is provided with of horizontal baffle 9.
1～50 millimeter of the thickness of each diaphragm structure of described horizontal baffle 9 is provided with 5 layers of diaphragm structure at least.
Described upper cover 1 is provided with liquidometer 8, and liquidometer 8 is used for lightweight oil liquid level in the Real Time Observation devulcanizer, and can be used as the reference of initial adding sweetening agent.
The diameter of described feed-pipe 4 is 20～500 millimeters, and the height of described tank body 3 is 300～5000 millimeters.
Adopt sweetener of the present utility model, by lightweight oil (as oil, petroleum naphtha etc., proportion is between 0.6～0.8,) pre-treatment, lightweight oil enters the high-efficiency desulfurization device processes, washing at last obtains qualified product, concrete sulfur removal technology process is: (described pre-treatment is alkali cleaning through pre-treatment, promptly adopting concentration is that the NaOH solution of 5～10wt% carries out prewashing) the mercaptan lightweight oil that contains enter by feed-pipe 4 and (adopt ram pump or hydro-pump to pump into, flow is 5～10t/h) in the tank body 3, lightweight oil under the guiding of multilayer horizontal baffle 9 fully and the sweetening agent effect in the tank body 3, since sweetening agent than lightweight oil than great, lightweight oil is above the liquid level of separating out the sweetening agent of coming tank body 3 inside under the guiding of horizontal baffle 9 gradually, form settled layer, and leave tank body 3 by discharge nozzle 5 at last, the lightweight oil of this moment was handled through sweetening agent, reached mercaptan removal thus, the purpose of depriving hydrogen sulphide.
