The main structure of the separation column mainly comprises a granulating column body, a spraying and granulating nozzle system and a lower discharge pot from top to bottom, wherein the granulating column body can be formed by a separation and precipitation section, a taper section and a jacket cooling system; the spraying and granulating nozzle system can be formed by a distributor master pipe and a plurality of distributor branch pipes; the distributor branch pipes are symmetrically distributed, and the jet direction of the outlets of the distributor branch pipes form a certain angle with the vertical direction, which can form a rotating flow field with tangential velocity; the jacket cooling system comprises a tangential cooling water outlet, a radial cooling water inlet and a jacket main body; and cooling water rotates and upwards flows in a jacket, separated particles rotate and downwards flow in the spraying and granulating separation column, and the rotating and flowing directions of the cooling water and the separated particles are opposite to form contranatant heat exchange. In the invention, rotating flow fields of different degrees can be formed in the granulating column through adjusting the angles of the charge distributor and the number of the distributor branch pipes to realize different particle distribution states and improve the gas-solid separation efficiency; and different heat exchange efficiencies can be realized through adjusting the temperature, the pressure and the flow rate of a cooling water inlet and the structural size of a cooling water jack, and then the particle temperature can be reduced to control the temperature of the granulating column.
Description
Affiliated technical field
The invention belongs to the chemical separation engineering plant equipment; Particularly relate to the mist projection granulating knockout tower that a kind of section of awl is provided with the chuck cooling system, can be applied to the mist projection granulating and the separation process of heavy oil step separating technology medium pitch residue, when realizing granulation and solvent and particle carried out high efficiency separation; Effectively absorb heat superfluous in the granulation tower; Guarantee the heat balance in the granulation knockout tower, and particle is cooled, help carrying out smoothly and next step conveying of particle of technology.
Background technology
In the overcritical step extraction and separation technology of heavy oil, depitching wet goods high-quality component after separating needs residues such as remaining pitch and colloid are carried out the flash boiling spray granulation, so that follow-up processing and application.In the mist projection granulating tower, the mixture of liquid flux under the HTHP (pentane) and pitch particle is ejection fast from nozzle, the solvent flashing vaporization; System temperature reduces; The atomizing of pitch and colloid is for after the fine drop, because the volatilization of solvent and the reduction of system temperature, condenses and is solid particle.Simultaneously, granulation tower also will possess the gas solid separation function, and the particle of producing separates with the solvent of vaporization fast, reuses so that reclaim solvent, reduces production costs.The ratio shared owing to solvent in the supercritical fluid is certain; In the mist projection granulating process, the heat that the solvent flashing vaporization is absorbed also deficiency has superfluous heat so that system temperature drops to set point of temperature in the granulation tower; Too high temperature is that separation, output and the packing of pitch particle brought difficulty; Too high temperature makes the pitch particle surfaces of tacky simultaneously, has increased the probability that particle agglomeration hardens, for system stable operation brings hidden danger.Therefore need adopt an effective measure, system further cools to granulation tower, reduces whole system and particle temperature in the granulation tower, is convenient to subsequent delivery.Because the asphaltic residue particle is under the temperature and solvent partial pressure condition of granulation tower environment; Still has suitable viscosity; In granulation tower, build bridge, stop up for fear of pitch particle; Inner member can not be installed in granulation tower, so in the tower cooling-part can not be installed, for the cooling of granulation tower and temperature control bring difficulty.The present invention proposes the granulation tower structure that a kind of section of awl is provided with the chuck cooling system, can under the condition that does not add inner member, cool off granulation tower, thereby address this problem.
