Tracheae one end, the oil sealing air inlet pipe other end connect washing oil storage tank, and washing oil tank top connects oil sealing escape pipe.
Further, it is equipped with oil sealing above the washing oil storage tank, oil sealing uses washing oil liquid for medium, and lower section is equipped with washing oil liquid
Storage tank, oil sealing air inlet pipe are inserted into liquid level or less；The gas of oil sealing air inlet pipe discharge will come into full contact with oil sealing, and maximal efficiency is removed
Pollutant, extra exhaust gas enter waste gas absorbing system by oil sealing escape pipe.
Further, the oil sealing on washing oil storage tank top is connected by washing oil circulation pipe with circulating pump one end, and circulating pump is another
Washing oil storage tank and washing oil discharge pipe with washing oil storage tank is held to be respectively connected with；Ensure that there are enough washing oil liquid in washing oil storage tank.
Further, flowing full mouth is equipped on the right side of washing oil storage tank, flowing full mouth is equipped with visor, and oil sealing is washed by the connection of flowing full mouth
Fluid storage tank；Flowing full mouth is able to maintain that oil sealing keeps certain oilseal height, visor that can observe washing oil loop condition at any time.
Further, it is equipped with liquid level gauge on the left of washing oil storage tank, the height of washing oil storage tank wash-in fluid can be controlled.
Compared with prior art, the utility model has the beneficial effects that：It can protect carbon black feed stock oil tank will not be because of pressure
Power is excessive or is damaged there are negative pressure, it is ensured that the safety and stability of carbon black feed stock oil tank；Oil sealing uses washing oil liquid
For medium, the escaping gas such as benzene, the naphthalene in carbon black oil oil gas can be absorbed, environmental pollution is avoided.

Specific implementation mode
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by.
Referring to Fig. 2, in the utility model embodiment, a kind of safety and environmental protection for production of carbon black carbon black feed stock oil tank
Device, including material outlet 1, carbon black feed stock oil tank 2, material inlet 3, nitrogen adjustment valve 4, breather valve 5, oil sealing air inlet pipe 6,
Washing oil storage tank 7, oil sealing escape pipe 8, washing oil circulation pipe 9, washing oil discharge pipe 11 and circulating pump 12；2 side of carbon black feed stock oil tank
Equipped with material outlet 1 and material inlet 3, top connects nitrogen adjustment valve 4 and breather valve 5；2 top of the carbon black feed stock oil tank
6 one end of oil sealing air inlet pipe is connected, 6 other end of oil sealing air inlet pipe connects washing oil storage tank 13, and 13 top connection oil sealing of washing oil storage tank goes out
Tracheae 7；13 top of the washing oil storage tank is equipped with oil sealing 15, and lower section is equipped with washing oil liquid storage tank 16, and oil sealing air inlet pipe 6 is inserted into oil sealing 15
Below liquid level；The oil sealing 15 on 13 top of washing oil storage tank is connected by washing oil circulation pipe 11 with 12 one end of circulating pump, and circulating pump 12 is another
