Description
Technical field
The present invention relates to the catalyst unloading technical field of tubular reactor in chemical industry, the petrochemical industry, relate in particular to the catalyst breakage device.
Background technology
Many chemical reactors are made into shell and tube heat exchanger, and it has many parallel, the vertical pipe that extends to the bottom tube sheet from the top tube sheet.During use, pipe all is equipped with catalyst usually, periodically the off-response device, draw off catalyst, cleaning pipe, and load new catalyst.In unloading the agent process, often can meet difficulty.More during catalyst changeout, the general method that adopts is to vibrate upward from the lower openings section of reactor with the ear of maize that metal bar or other materials are made, and the catalyst of reactor tube inside is fallen.All pipes in the reactor or some pipes are because thermal change or the change of component in the running, catalyst in the pipe hardens in the reactor running fully, perhaps build bridge, can't directly extract out by vacuum plant, cause unloading the increase of agent difficulty, reduce the speed that draws off of catalyst.Increase owing to unload the time of agent, prolonged the downtime of reactor, have a strong impact on the economic benefit of chemical industry, petroleum chemical enterprise.
A kind of catalyst breakage preparation-unloading method is disclosed in No. 5228484 specifications of U.S. Patent No., insert nozzle to inside by the reaction tube upper end, blow out pressure-air from nozzle tip, make the catalyst of filling in the reaction tube become loose with pressure-air, perhaps make it have flowability, with its upper end that is transported to reaction tube, send into and be arranged on being full of in the chamber of reaction tube upper end, after will being full of the chamber vacuum exhaust, discharge catalyst.
Although the described method of above-mentioned United States Patent (USP) is feasible, but in practical operation, there is more problem, especially when catalyst seriously hardens, pressure-air by nozzle can't so that catalyst become loose, unload the agent operation and can't carry out, and pressure-air need to arrange compressor, install loaded down with trivial details, if tubular reactor has hundreds of and even tens thousand of reaction tubes, the required pressure of pressure-air can increase, and using to increase danger.
Situation for the tubular reactor catalyst seriously hardens does not also form a kind of effective broken preparation-unloading method at present, and is general still by manually vibrating with pipe.Tubular reactor has hundreds of and even tens thousand of reaction tubes usually, adopts manual method, time-consuming, effort not only, and it is very low to unload agent efficient, and the dust environmental pollution that produces when unloading agent is serious.
Summary of the invention
The problem that catalyst hardens when unloading agent for existing tubular reactor, the present invention has designed a kind of novel tubular reactor catalyst breakage aspirator, that can not only improve catalyst unloads agent efficient, add the quick-release agent time, and produce the problem of dust pollution when also not unloading agent, can solve fully catalyst seriously harden broken difficult.
Its technical scheme is: a kind of tubular reactor catalyst breakage unloads the agent device, this device is provided with the base bend pipe by base support on this base, base bend pipe and base communicate, the place is provided with the suction tube head at the base bend pipe mouth of pipe, and base bend pipe and suction tube head are tightly connected; Be provided with the extension bar fixed sleeving that can pass through for electronic mashing device near the mouth of pipe place of base bend pipe, and electronic mashing device and extension bar fixed sleeving are in sealing state; Described electronic mashing device is fixed by support bar.
Described electronic mashing device is comprised of motor, the rotating band moving axis that links to each other with motor and the drill bit that is arranged on rotating band moving axis top.
The described rotating band moving axis that links to each other with motor is provided with extension bar, is threaded connection between the extension bar.
Described support bar is arranged on the base.
The motor of described electronic mashing device is fixed by the sliding bearing on the support bar.
Described base bottom is provided with rubber blanket.
This device is by support bar, sliding bearing, motor, extension bar, extension bar fixed sleeving, bend pipe, suction tube head, base, valve rubber, drill bit, this device is fixed on the mouth of pipe when carrying out the suction of tubular reactor catalyst, the vacuum draw machine is connected on the suction tube head of this device by pipeline.With with the axle of the drill bit extension bar by this device fixedly running-on reach the pipe the inside that catalyst is housed, utilize the rotating band moving axis of motor and drill bit with the catalyst breakage in the pipe, take away by the vacuum draw machine.The effect that valve rubber plays sealing and prevents from the boiler tube mouth is scratched, motor is connected with sliding bearing, can be by sliding bearing slide up and down moving up and down of drive motor, be threaded connection between the extension bar, when extension bar falls short of, two joint extension bars can be outwarded winding from the centre, be continued to connect extension bar.This tubular reactor catalyst breakage preparation-unloading method and equipment can be widely used in the fields such as petrochemical industry, chemical industry.
Beneficial effect: the tubular reactor catalyst breakage aspirator of new research and development utilizes the rotating band moving axis of motor and drill bit with the catalyst breakage in the pipe, can solve the Crushing Problem of the catalyst that seriously hardens fully, not only reduced and unloaded the agent difficulty, but also shortened the catalyst unloading time.The applicability of new equipment is stronger, possesses unique extension bar fixed sleeving, when extension bar falls short of, two joint extension bars can be outwarded winding from the centre, continues to connect extension bar.
