Description
Technical field
The invention belongs to petroleum refining industry delayed coking unit field, particularly a kind of automatic open/close device (equipment) of the last tower mouth of coke drum.
Background technique
Delayed coking is a kind of oil secondary operations technology, is that the heavy oil with poor hydrogen is raw material, is warmed up to the pyrogenetic reaction temperature rapidly through oven, enters coke drum and carries out pyrogenetic reaction.Heavy oil is through thermal cracking and the condensation reaction of the degree of depth in 500 ℃ high temperature, and the gas of producing, gasoline, diesel oil, wax oil are transported to downstream unit by pipeline and handle, and hundreds of kiloton coke of going up of producing remain in the coke drum.Coke in the coke drum progressively is cooled to below 120 ℃ by steam, water, pull down the upper and lower end socket lid of coke drum then, coke in the coke drum is removed clean with hydraulic decoking equipment, refill the upper and lower end socket lid of coke drum, enter next step production cycle: oil-feed, reaction, cooling, decoking etc.
Past oil refinery delayed coking unit is in process of production during coke removal, all need by weigh several tons blind lid and the supply pipe of the upper and lower tower mouth of coke drum of manual operation dismounting, once need nearly two hours, and operator are scalded by water, steam easily, exist great potential safety hazard, the discharging of a large amount of coke cooling waters also is unfavorable for environmental protection.
The tower mouth device that successively the tower mouth is used on coke drum has up to now:
1. tower top cover open-and-close mechanism: this mechanism adopts the blind lid of end socket and coke drum mouth employing hinge-coupled, with two blind lids of Driven by Hydraulic Cylinder end socket folding function that realizes overturning, and utilized hydraulic system in the folding power.The end socket lid also wants the operator to come dismounting by pneumatic tool with the connecting bolt group of coke drum.Cover the requirement of automatic folding though this mechanism has tentatively realized tower mouth end socket, also fundamentally do not break away from the dependence to operating manpower.
2. automatic top cover machine: this type top cover machine end socket lid connects with adopting hydraulic bolt dish spring pretension being connected of coke drum, injects the pretightening force that the hydraulic oil off-load falls to be added in advance tower mouth connecting bolt dish spring during folding, drives end socket by hydraulic jack again and covers Unscrew.The application of this top cover machine makes operator thoroughly break away from manual labor, realizes the automation mechanized operation of coke drum flap.Because equipment has been introduced hydraulic system assemblies such as hydraulic bolt, oil hydraulic cylinder, to having brought certain complexity, inconvenience on the operation and maintenance.
The model utility content
The purpose of this utility model provides a kind of novel flat top cover machine, is used for promoting the handling and Security of existing weaponry and equipment to realize the demand of remote automation control.
For realizing above-mentioned technical purpose, the technological scheme that adopts is: a kind of novel flat top cover machine, comprise the valve body body, adpting flange, fixed valve base, simple eye valve plate, floating valve seat, flange floats, valve rod, divide body nut, valve gap, trapezoidal screw, speed changer and electric actuator, fixed valve base is fixed on the valve body body by adpting flange, in the valve body body, be provided with floating valve seat and unsteady flange below the valve plate, floating valve seat and unsteady flange be nested the connection up and down, the valve body body, fixed valve base and floating valve seat form a passage that is used for simple eye valve plate horizontal motion, be provided with valve rod in channel outlet, one end of simple eye valve plate is connected with valve rod, valve rod is connected with trapezoidal screw by dividing body nut, electric actuator is connected with speed changer, and the output shaft of trapezoidal screw and speed changer is connected.
Unsteady flange described in the utility model below is provided with the high temperature spring element.
Adpting flange described in the utility model and fixed valve base are loop configuration, are provided with the elastic packing pad between the two.
Simple eye valve plate described in the utility model is the flat valve plate.
High temperature elastic element described in the utility model is refractory alloy helical spring or dish spring.
The beneficial effects of the utility model are: this equipment is simple to operate, easy to use, by electronic actuator smooth transport power, reduced complexity and the inconvenience in the Operation and Maintenance, not only realize automation mechanized operation at decoking process, also can realize the joint control operation with miscellaneous equipment, the operating security of coke drum and productivity all are greatly improved.The plant automation level has been shortened the delayed coking net cycle time, improves working environment, improved in coming into operation of equipment important practical sense.
