Abstract
Three phase slurry bed reactor sandwich-type distributor, by two pieces of interlayers 1 and 3 up and down, interlayer clamping forms Y shape bifurcated passage, and the gas passage of interlayer has the Spherical pellets 2 for preventing solid blocking channel, and two clamping plates flange form connects 6, and gas inlet pipe 4, escape pipe 5 is constituted.
Description
Technical field
The invention belongs to field of chemical equipment, it is adaptable to gas-solid-liquid three phase slurry bed reactor, compared to common distribution
Device, the reactor can avoid the occurrence of solid material block material channel, cause raw material can not by the problem of.
Background technology
Three phase slurry bed is widely used in daily industrial production, if using common distributor, it is possible to occurred following
Several situations.
When reactor is stopped, the athletic meeting of material gradually slows down, and starts to settle and condense toward the bottom of reactor
Together, there is no power at the distributor passage in reactor bottom, the situation for easily occurring blocking is occurred.
In reactor work way, slurry material viscosity is excessive, and the solid holdup of slurry material is higher, and blocking also would tend to occur
The situation of distributor.
Before reactor work, in the filling way of solid material, because no gas enters reactor, distributor gas leads to
There is no power at road, it is also possible to the situation of feed blocking bottom distributor occur.
When clogging occurs in distributor, the gas in reactor cannot uniformly be distributed, may influence reaction
The progress of the running and reaction of device.
In existing distributor, otherwise it is exactly no anti-blockage function, otherwise just very complicated structure, it is uniform for needing
For the reactor of gas distribution and anti-clogging leakproof, complicated gas distributor needs many, so as to cause the cost of reactor
Greatly promote.
The content of the invention
Hold susceptible to plugging shortcoming when being worked by understanding common distributor in slurry bed system, design one and both made simple
It can solve the problems, such as to accompany a Spherical pellets at 2 pieces of interlayers, gas passage above and below the new distributor of anti-clogging leakproof, distributor again,
Each gas passage is provided with 2 or multiple outlets.
Brief description of the drawings
Fig. 1 is the cross-sectional view of clamping plate distributor.
Fig. 2 is longitudinal schematic diagram of clamping plate distributor.
Fig. 3 is the clamping plate schematic diagram up and down of clamping plate distributor.
Fig. 4 is longitudinal schematic diagram of clamping plate distributor.
Fig. 5 is the clamping plate schematic diagram up and down of clamping plate distributor.
Embodiment
When before reactor work or when being stopped, solid material accumulation is deposited in bottom, and now bead is because of the work of gravity
Blocked with feeder connection, protect the gas passage of distributor, prevent solid material blocking channel.When reactor works,
Blocking the bead of passage, one outlet is moved thereto under the promotion of gas, it is ensured that gas passage it is unimpeded, gas passes through
The other outlet discharge of the passage.For common distributor, the appearance of above-mentioned situation can cause the problem of distributor is blocked to be sent out
It is raw, but this design can be protected in the case where reactor down-time, filling solid material, reactor slurry material viscosity are excessive and divided
Cloth device is not blocked, can guarantee that reactor normal work and with smooth shutting down.
2 pieces of interlayers are mutually matched above and below the distributor, and train wheel bridge can design 2 ~ 4 outlets according to actual conditions, and 2 go out
During mouth, anti-blocking bead moves to one of outlet, and gas flows out from another outlet；During multiple outlets, bead is moved to
One of outlet, gas is distributed from other outlet.
Claims (3)
1. three phase slurry bed reactor sandwich-type distributor, is made up of two clamping plates and anti-blocking bead.
2. sandwich-type distributor according to claim 1, it is characterized in that being made up of 2 pieces of interlayers up and down, 2 pieces of interlayer clamping shapes
Into Y shape bifurcated passage, the gas passage of interlayer has 1 to prevent the Spherical pellets of solid blocking channel.
3. sandwich-type distributor according to claim 1, it is characterized in that circular anti-blocking bead can be left in bifurcated passage
Right motion.
