Description
Technical field
The utility model belongs to field of chemical equipment, particularly relates to a kind of methylphenylamine vacuum tail gas recycle device.
Background technology
The petrochemical enterprise of China is more, and therefore rectifier unit is more, and especially for high boiler material, be all the rectification under vacuum adopted from the energy and operation, thus inevitable vacuum tail gas is more.Although take a series for the treatment of measures and develop some treatment facilities, in fact still cannot process completely.Due to the development of existing industrial economy and the contradiction of social environment, the requirement of people to environment is more and more higher, and country is also more and more stricter to relevant environmental protection.Therefore, how to reduce the vacuum waste gas produced in production process, prevent and alleviate ambient influnence, a new problem is proposed to most enterprises.In such a case, methylphenylamine vacuum tail gas Appropriate application safety device arises at the historic moment.Existing vacuum tail gas is all through a series of process and directly discharges afterwards, still has a certain impact to surrounding environment, if adopt incineration technology, not only can utilize heat energy in waste gas, can also reduce toxic emission.But, because vacuum system is negative pressure, once there be oxygen to enter, then can be mixed into damp, and produce major accident.Therefore, adopt suitable technology, guarantee that process units is safely primary and foremost purpose.
At present, methylphenylamine vacuum tail gas, all adopts the pattern of emptying after absorbing.The method exists changes adsorbent complexity, the amount of labour greatly, and to shortcomings such as ambient influnence are large.
Therefore a kind of device that thoroughly can solve methylphenylamine vacuum tail gas is needed.
Summary of the invention
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of Automated condtrol, on-line checkingi oxygen content, and the methylphenylamine vacuum tail gas recycle device that security is higher.
The technical solution adopted in the utility model is such: a kind of methylphenylamine vacuum tail gas recycle device, it is characterized in that: comprise vacuum buffer tank, online oxygen analysis checkout gear, vavuum pump, absorption tower, stop valve, chimney, surge tank, water sealed tank and oil oven, described vacuum buffer tank to be connected online oxygen analysis checkout gear, vavuum pump, absorption tower, stop valve, chimney, surge tank, water sealed tank and oil oven successively by pipeline.
Further in order to equipment safety, prevent oxygen from entering, be mixed into damp, and produce major accident, described online oxygen analysis checkout gear has 3, be provided with the first online oxygen analysis checkout gear between described vacuum buffer tank and vavuum pump, between described absorption tower and surge tank, be provided with the second online oxygen analysis checkout gear, between described water sealed tank and oil oven, be provided with the 3rd online oxygen analysis checkout gear.
Described stop valve has 2, is provided with the first stop valve between described absorption tower and chimney, is also provided with the second stop valve between described absorption tower and surge tank.
Further, for decreasing toxic emission, between described absorption tower and chimney, be also provided with active carbon adsorber.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: by the oxygen content on-line analysis of vacuum tail gas and automatically control, achieve the comprehensive utilization of vacuum tail gas energy, security reliability is high, decrease toxic emission, reach the object of cleaner production, improve economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 is vacuum buffer tank, and 2 is vavuum pump, and 3 is absorption tower, 4 is chimney, 5 is surge tank, and 6 is water sealed tank, and 7 is oil oven, 8 is the first online oxygen analysis checkout gear, 9 is the second online oxygen analysis checkout gear, and 10 is the 3rd online oxygen analysis checkout gear, and 11 is the first stop valve, 12 is the second stop valve, and 13 is active carbon adsorber.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of methylphenylamine vacuum tail gas recycle device, comprise vacuum buffer tank 1, vacuum buffer tank 1 to be connected vavuum pump 2 successively by pipeline, absorption tower 3, chimney 4, surge tank 5, water sealed tank 6 and oil oven 7, the first online oxygen analysis checkout gear 8 is provided with between vacuum buffer tank 1 and vavuum pump 2, the second online oxygen analysis checkout gear 9 is provided with between absorption tower 3 and surge tank 5, the 3rd online oxygen analysis checkout gear 10 is provided with between water sealed tank 6 and oil oven 7, the first stop valve 11 is provided with between absorption tower 3 and chimney 4, the second stop valve 12 is also provided with between absorption tower 3 and surge tank 5, active carbon adsorber 13 is also provided with between absorption tower 3 and chimney 4.
From the vacuum tail gas of system, before vavuum pump 2 after the first online oxygen analysis checkout gear 8 oxygen content detects, enter absorption tower 3 through vavuum pump 2 to absorb, mixed material after absorption is back to system recoveries, comprehensive utilization, gas enters surge tank 5 after the second online oxygen analysis checkout gear 9 oxygen content detects, then after water sealed tank 6, again after the 3rd online oxygen analysis checkout gear detection is qualified, oil-feed stove 7 burns, heat is provided to conduction oil, once the first online oxygen analysis checkout gear 8, second online oxygen analysis checkout gear 9, 3rd online any one oxygen content of oxygen analysis checkout gear 10 exceeds standard, then automatically open the first stop valve 11, cut off the second stop valve 12, vacuum tail gas discharges through chimney 4 after active carbon adsorber 13 adsorbs, guarantee oil oven 7 safety, only have three places to detect oxygen content all to meet the requirements, just switch cut-out first stop valve 11, open the second stop valve 12.
The beneficial effect of the present embodiment is: by the oxygen content on-line analysis of vacuum tail gas and automatically control, and achieve the comprehensive utilization of vacuum tail gas energy, security reliability is high, decreases toxic emission, reaches the object of cleaner production, improves economic benefit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
