Each gas distribution valve comprises a supporting plate and a working plate capable of being opened unidirectionally, wherein the supporting plate and the working plate are arranged longitudinally along the wall of each distribution branch pipe, and vent holes are arranged on the surface of the supporting plate. The gas distributor can realize uniform gas distribution, prevent back-flowing of slurry effectively and realize adjustability of gas flow, and has the advantages of self-cleaning performance and long service life.
Description
Technical field
The utility model relates to a kind of gas distributor, the gas distributor that relate in particular to interior gas, liquid, solid three-phase of a kind of fixed container or gas, uses when the liquid two-phase is mixed stirring.
Technical background
In some metallurgy, chemical industry, need gas to participate in reaction in its production technology, this just needs to carry out the mixing plant of gas-liquid two-phase or gas-liquid-solid three-phase mixing.In the reactor of industrial circles such as gas distributor is widely used in refining oil, Coal Chemical Industry, chemical fertilizer, pharmacy, particularly relate in the device of heterogeneous fluidization reaction.For realizing that gas evenly distributes, should guarantee to produce desirable pressure drop by gas distributor, about effect, the pressure of gas distributor in the fluid bed fall calculate and and the type of bed stability relationship, gas distributor can reach " the corresponding introduction of Chemical Engineering handbook referring to the military academician's of Chen Jun monograph " catalytic cracking process and engineering (second edition) " chapter 5 and chapter 8.
The gas distributor of present industrial use mainly contains two types of board-like gas distributor and tubular gas distributors, gas distributor will be subjected to the restriction of two aspects at least, one constant pressure drop is arranged so that realize that distribution of gas is even, and exit velocity is difficult for too high, avoids causing the nozzle outside to wash away, wear and tear.Chinese patent CN201020128922.8 discloses a kind of gas distributor, comprises being located at the outside breather pipe in reactor bottom, also comprises and is located at the inner distributor pipe in reactor bottom, and breather pipe is connected with distributor pipe, and described distributor pipe is provided with the distribution hole.This gas distributor is simple in structure, and is easy to operate, when product obstruction passage need be dredged, only with opening discharge valve directly from the mediation of reactor bottom.Chinese patent CN200920153148.3 discloses a kind of gas distributor, and its nozzle is made up of gas inlet tube, the taper increaser of fixed diameter, outer coated metal outer wall, and this nozzle is welded on the gas distributor associated components.
This gas distributor carries out the nozzle geometry architecture advances by tubular gas distributor that has commercial Application now or board-like gas distributor and forms, the layout of nozzle and number are required to decide by distributor pattern, reactor pattern and reaction process, evenly distribute to guarantee air-flow.When adopting nozzle when improved tubular gas distributor is operated, gas at first enters gas distributor, and the tube connectors such as the person in charge, arm of flowing through enter the gas inlet tube on the nozzle, by the ejection of taper increaser, carry out the gas uniform distribution after the step-down; When adopting nozzle when improved board-like gas distributor is operated, high velocity air enters the gas inlet tube on the nozzle from bottom to top, by the ejection of taper increaser, carries out the gas uniform distribution after the step-down; The design of nozzle taper increaser, thus avoided existing commercial Application nozzle since air-flow advance at extension diameter section because of volume expansion cause the refluxing defective of erosion nozzle inner tubal wall.
Summary of the invention
The utility model provide a kind of gas distribution evenly, can prevent effectively that slip from pouring in down a chimney, tolerance is adjustable, have self-cleaning performance, and the gas distributor of long service life.
The utility model is achieved by the following technical solution:
Gas distributor, comprise and be located at the inner person in charge, the dispensing branch in fixed container bottom, the described person in charge is connected with dispensing branch, the port of export of described dispensing branch also is provided with gas distributing valve, described dispensing branch and gas distributing valve are tightly connected, described gas distributing valve is that the working plate by gripper shoe and unidirectional unlatching constitutes, and described gripper shoe and working plate and dispensing branch tube wall vertically are provided with, and the plate face of described gripper shoe is provided with passage.
Described gas distributing valve also comprises adjusting pad and pressing plate, and described gripper shoe, working plate, adjusting pad and pressing plate are successively set on the tube wall of dispensing branch, and the corresponding dispensing branch tube hub with pressing plate of described adjusting pad is provided with through hole.
Described working plate is the fluorubber plate, and the right-angled intersection of described fluorubber plate plate face has oblique profile.
Operation principle of the present utility model: gas is delivered to gas distributor by air compressor machine by pipeline, entering distributor is responsible for, give gas distributing valve by many dispensing branch uniform distributions, after venting pressure and tolerance reach certain condition, the unidirectional automatic unlatching of working plate reaches the function of disperseing gas; When air intake valve is closed, can close operation element automatically by the static pressure of liquid in the groove, prevent that material from pouring in down a chimney.
The beneficial effect of the utility model gas distributor:
1, gas distribution is even.Working plate is made up of the fluorubber plate of polylith acid-alkali-corrosive-resisting, under the certain condition of venting pressure and tolerance, the unidirectional unlatching of working plate has enough big permeability, guarantee that gas output is not affected, many dispensing branch are that same specification stainless steel tube is made, uniform fixed container bottom guarantees that gas distribution is even.
2, prevent that slip from pouring in down a chimney.After the design of special construction can guarantee that air intake valve is closed, order about working plate by liquid generation geostatic pressure in the groove and close automatically, the right-angled intersection of plate face has oblique profile, guarantees the working plate hermetically closing, slip can not pour in down a chimney and enters admission line like this, thereby avoids the obstruction of admission line.
3, long service life.The existence of gripper shoe can slacken pressure when excessive, and gas prolongs the service life of working plate to the impact of working plate; The while gripper shoe can be resisted ore pulp after air valve is closed static pressure does not enter in the gas pipeline ore pulp.
4, tolerance is adjustable.Can change the thickness of adjusting pad according to process requirements, satisfy the requirement of different tolerance.
5, self-cleaning performance.Usually the gas distributor long period of soaking is easy to and can stops up the gas outlet in outlet side interruption-forming fouling in slip, influences service life.And this gas distributor is in when work, and working plate is that the fluorubber plate is in the elastic deformation state all the time under the gas percussion, and the fouling that can effectively come off reaches the automatically cleaning effect.
