Description
Technical field
The present invention relates to pyrolysis desorption tail gas processing technology field, the clarifying smoke for being more particularly, to pyrolyzed desorption fills
It puts.
Background technology
The tail gas that pyrolysis separating process generates has following features：Containing Dust Capacity is big, moist and band is corrosive, temperature is then general
All at 100 DEG C or more.If the tail gas that pyrolysis separating process generates is directly discharged into air and can cause environmental pollution, and existing skill
The dedusting and purifying device effect used in art is undesirable.
A kind for the treatment of process of oil-base mud is disclosed in 2015103141129 specification of Chinese invention patent application number.
The system is to realize clarifying smoke, this method energy consumption by increasing gas/liquid separator device separation using thermal desorption device
Height, and it be easy to cause secondary pollution.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of for being pyrolyzed the clarifying smoke of desorption dress
It puts, which is suitble to the tail gas that processing pyrolysis separating process generates.
To achieve these goals, technical scheme is as follows：
For being pyrolyzed the smoke and dust purifier of desorption, including dust cleaning case, dust cleaning case has air inlet and gas outlet, is set in dust cleaning case
Spray head is equipped with, the dust cleaning case is a tube body, and spray head is arranged along the extending direction of tube body, and gear is provided in dust cleaning case
Plate, the water outlet of spray head is towards baffle or is directly toward the inner wall of dust cleaning case.
Unlike the prior art, the application uses a tube body as dust cleaning case, can be before equipment volume is not increased
It puts, extends residence time of the tail gas of pyrolysis separating process generation in dust cleaning case.Point of the dust content in pipeline section
Cloth is usually that top is more than lower part.The application arranges baffle on the top of pipeline, and on baffle, baffle is sprayed again for dust building
Head ceaselessly washes away, and substantial amounts of dust is made to glide along baffle.There is no the space of baffle（Refer mainly to the middle and lower part of pipeline）Removal
Dust is mainly by following two kinds of modes：First, the dust of high-temperature flue gas entrainment is directly washed away by spray head；Second is that it leans on along baffle
The impact of the moist dust slided,, can during whereabouts since the moist dust proportion slided from baffle is larger
Fall the dust of the middle and lower part of pipeline with band simultaneously.So this programme has high-temperature flue gas preferable cooling and dust removing effects.And
And bump against since dust is most of with baffle, there is constantly washing away for spray head on baffle again, so, not only it is not easy to tie on baffle
Coke is not easy to coking inside pipeline.
As an improvement, the dust cleaning case includes at least 1 horizontal tube and 1 VERTICAL TUBE.High-temperature flue gas is in horizontal tube with erecting
The tie point of straight tube is there are one the active force of rebound of being obstructed, and during rebound, makes dust that opposite shock occur, has preferable dedusting to imitate
Fruit.
As a further improvement, the dust cleaning case includes 2 horizontal tubes and 1 VERTICAL TUBE, 2 horizontal tubes are arranged up and down,
On the underlying horizontal tube of air inlet, on the horizontal tube that gas outlet is located above.After 2 horizontal tubes are set, the water from top
High-temperature flue gas of the flush water that flat pipe flows down with rising at VERTICAL TUBE collides in opposite directions, generates preferable dust removing effects.
As an improvement, the total length of the dust cleaning case is at least 2 meters, have to ensure high-temperature flue gas in dust cleaning case enough
Residence time.
As an improvement, the dust cleaning case is equipped with spray piping, spray piping is arranged along the extending direction of tube body, spray head
It is connected on spray piping.
As an improvement, the dust cleaning case is equipped with fixed frame, fixed frame arranges that baffle is fixed on along the extending direction of tube body
On fixed frame.
As an improvement, the angle between the baffle and fixed frame is 40 °~140 °, make baffle to coming out from spray head
Flush water has a rebound of different angle, reduce wash away less than dead angle.
As an improvement, the lower edge position of the baffle is no more than the central axes in dust cleaning case section.It tests and finds through applicant,
If baffle shelters from excessive pipeline section, the pressure in dust cleaning case can greatly increase or even occur the anti-situation about filling of flue gas,
High-temperature flue gas can come out instead from air inlet.If the lower edge position of baffle is no more than 1/3rd of dust cleaning case cross-sectional length,
Situation is with regard to more satisfactory.At this point, flowing of the high-temperature flue gas in pipeline is more unobstructed, while dust removing effects are also preferable.
As an improvement, the section of the baffle is S-type.S types section is conducive to have not the flush water come out from spray head
With the rebound of angle.
In conclusion the present invention has the characteristics that structure novel, design are reasonable, have preferably to the dust in high-temperature flue gas
Removal effect, and the inner wall of dust cleaning case is not easy coking.
