Abstract
The utility model discloses an improved crude phenol refined exhaust effusion discharging device, comprising a vacuum pump. A gas inlet of the vacuum pump is communicated with a gas collecting cabinet by an intake tube; an exhaust port of the vacuum pump is communicated with an exhaust buffer tank by an exhaust tube; and the exhaust tube is communicated with an exhaust effusion receiving tank which is lower than the exhaust port of the vacuum pump. By adopting the improved discharging device, exhaust effusion can be smoothly discharged into the exhaust effusion receiving tank and can be discharged timely, so that the exhaust effusion is not accumulated in the exhaust tube of the vacuum pump, the exhaust resistance of the vacuum pump is reduced, the service life of the vacuum pump is effectively prolonged, the safety of equipment is ensured, and the vacuum degree can be effectively stabilized in production process and can be adjusted according to process requirements.
Description
Technical field
The utility model relates to refining of crude phenol production unit technical field, specifically, relates to a kind of improved device that the tail gas hydrops that produces in the refining of crude phenol production process is discharged.
Background technology
At present; The discharging modes of the tail gas that produces in the refining of crude phenol underpressure distillation production process are: tail gas is collected by the gas collection cabinet earlier; Be delivered to tail gas buffer by vacuum pump again; Gas part in the tail gas enters in the air from the tail gas buffer top, and the tail gas hydrops that water of condensation and pump oil are contained in the tail gas buffer bottom drains into waste water tank by pump in addition.In the discharge process, the good operation of vacuum pump is vital to the influence of producing, in the existing tapping equipment, because vacuum pump vapor pipe to tail gas buffer has certain height; Vacuum pump is lower than tail gas buffer, so the resistance of exhaust of vacuum pump is very big, the hydrops row in the pipeline is unclean, has strengthened the resistance of bottom exhaust emissions; Influenced the works better of vacuum pump plunger shaft, caused the heating of vacuum pump pump head, the exhaust temperature of discharge is too high; Can reach more than 70 ℃, cause the vacuum pump pulling vacuum unstable, and the vacuum pump vent valve be prone to carbon distribution; Influence the work-ing life of vacuum pump, Yin Wendu is too high, and tail gas also has the incendiary possibility.Therefore,, guarantee the continual and steady of production vacuum, create good working condition, press for existing tail gas hydrops tapping equipment is improved in order to guarantee device security.
Summary of the invention
The utility model technical problem to be solved is: a kind of improved refining of crude phenol tail gas hydrops tapping equipment is provided, to reduce the resistance of exhaust of vacuum pump, makes the vacuum pump vapor pipe not stockpile liquid, guarantee device security.
For solving the problems of the technologies described above; The technical scheme of the utility model is: improved refining of crude phenol tail gas hydrops tapping equipment; Comprise vacuum pump, the inlet mouth of said vacuum pump is through inlet pipe connected set gas holder, and the venting port of said vacuum pump is communicated with tail gas buffer through vapor pipe; Said vapor pipe also is communicated with tail gas hydrops reception tank, and said tail gas hydrops reception tank is lower than the venting port of said vacuum pump.
Owing to adopted technique scheme, the beneficial effect of the utility model is: because the vapor pipe of this improved refining of crude phenol tail gas hydrops tapping equipment also is communicated with tail gas hydrops reception tank, tail gas hydrops reception tank is lower than the venting port of vacuum pump; Like this, the tail gas hydrops just can successfully be discharged in the hydrops reception tank, regularly discharges; Do not stockpile liquid in the vacuum pump vapor pipe; Reduce the resistance of exhaust of vacuum pump, effectively prolonged the work-ing life of vacuum pump, guaranteed device security; It is effectively stable that vacuum tightness has been accomplished in production process, can regulate according to processing requirement.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Accompanying drawing is the exhaust emissions schematic flow sheet behind employing the utility model;
Among the figure: 1-gas collection cabinet; The 2-inlet pipe; The 3-vapor pipe; The 4-tail gas buffer; 5-tail gas hydrops reception tank; The 6-vacuum pump.
Embodiment
Shown in accompanying drawing; Improved refining of crude phenol tail gas hydrops tapping equipment; Comprise vacuum pump 6, the inlet mouth of said vacuum pump 6 is through inlet pipe 2 connected set gas holders 1, and the venting port of said vacuum pump 6 is communicated with tail gas buffer 4 through vapor pipe 3; Said vapor pipe 3 also is communicated with tail gas hydrops reception tank 5, and said tail gas hydrops reception tank 5 is lower than the venting port of said vacuum pump 6.
This improved refining of crude phenol tail gas hydrops tapping equipment is when discharging tail gas, and tail gas is collected by gas collection cabinet 1 earlier, after inlet pipe 2, vacuum pump 6 and vapor pipe 3 are delivered to tail gas buffer 4; Gas part in the tail gas enters in the air from tail gas buffer 4 tops, because tail gas hydrops reception tank 5 is lower than the venting port of vacuum pump 6, like this; Before getting into tail gas buffer 4, the tail gas hydrops just can successfully be discharged in the hydrops reception tank 5, regularly discharges; Do not stockpile liquid in the vacuum pump vapor pipe; Reduce the resistance of exhaust of vacuum pump 6, effectively prolonged the work-ing life of vacuum pump, guaranteed device security; It is effectively stable that vacuum tightness has been accomplished in production process, can regulate according to processing requirement.
The above is giving an example of the utility model preferred forms, and the part of wherein not addressing in detail is those of ordinary skills' common practise.The protection domain of the utility model is as the criterion with the content of claim, and any teachings and equivalent transformation of carrying out based on the utility model is also within the protection domain of the utility model.
