The angle that the central axes in road 32 are formed is 8-15 °, such as 8 °, 10 °, 12 °, 15 °.This kind setting makes high-temperature steam have spray upwards
Two component motions with horizontal-jet are penetrated, high molecular polymerization raw material is made while horizontal and vertical agitation occurs, are further mentioned
High stirring effect, and high-temperature steam is made to impact high molecular polymerization raw material upwards, drive high molecular polymer raw material horizontal
And vertical movement, 1 inner macromolecule polymer raw material of tower body are more uniform；Also, main channel 32 and horizontal plane are slightly tilted centainly
Angle, it is ensured that gas with certain rotation direction flows into wing passage, transition effect with higher from main channel.
The diameter of the main channel 32 becomes larger from one end of main jet port towards the one end connecting with the air flue 31,
The diameter of one end that the main channel 32 is connect with the air flue 31 is 1.30 times of the main jet port diameter, or
Arbitrary value in 1.30-1.40 times, such as 1.40 times.
Since wing passage 33 has shunted some vapor from main channel 32, steam jet velocity is reduced in order to prevent, will be led
The diameter of puff prot is set as 1.30-1.40 times smaller than 32 inlet of main channel, guarantees to spray speed from the steam of main jet port
Degree.
Further, it is along the distance of two adjacent blades of the shaft vertical axis in the vertical direction
400-600mm, such as 400mm, 500mm, 600mm, the blade positioned at lower on the blade 22 of adjacent two
The diameter of the main jet port and the side spray port on 22 is the main jet port on the blade 22 of eminence
With 1.1 times of the diameter of the side spray port, or the arbitrary value in 1.1-1.2 times, such as 1.2 times.
The distance of the blade 22 of adjacent two in the vertical direction is 400-600mm, while on different blades 22
The diameter of the main jet port and the side spray port is gradually reduced with the increase of height, and the jet amount made increases also with height
Add and reduces, since highly higher 22 chaotropic face of blade is closer, the high temperature of the puff prot ejection on the higher blade 22 of height
Residence time of the steam in the high molecular polymer raw materials for production of liquid is shorter, thus in order to guarantee all high-temperature steams
It can liquefy completely, thus by the diameter of main jet port described on different blades 22 and the side spray port with the increase of height
It is gradually reduced, to make full use of steam.
Further, the shape near the blade 22 of 1 bottom of tower body is arch, is had and 21 axis of shaft
Parallel vertical spout.Preferably, the diameter of the vertical spout is 75mm, and as deformation, the vertical spout is also possible to
Arbitrary value in 50-80mm, such as 50mm, 60mm, 70mm, 80mm.
Shape near the blade 22 of 1 bottom of tower body is arch (being arch blade 23 in Fig. 1), pastes blade 22
The shape setting of 1 bottom of tower body is closed, and vertical spout 34 is set on blade 22, improves the polyphosphazene polymer to 1 bottom of tower body
Close the stirring effect of object.
Not into one, it is connected at sustained height position, in the shaft 21 and controls two blades 22, described in side
The wing passage 33 on blade 22 tilts down extension, and the wing passage 33 on blade 22 described in the other side upwards prolong by inclination
It stretches.So that injection, the amount of the gas sprayed downwards are roughly the same upwards, to guarantee the one of reaction vessel interior pressure
It causes.
Further, limited valve is arranged in the other end of the main channel 31.
Limited valve is arranged in the other end of the main channel 31.Pressure limiting valve is beaten automatically in the hypertonia of main channel 31
It opens, discharge section gas, hypertonia in main channel 31 can be prevented and damage agitating device.
Further, relief valve is set on the side wall of the tower body, and when hypertonia of the pressure limiting valve in reaction tower is automatic
It opens, discharge section gas, reaction tower pressure interior force can be prevented excessively high and cause explosion danger.
Pyroreaction system described in above-described embodiment is as shown in Figure 1 cylindrical shape, or other shapes, such as
Triangle, the angle of apex angle are greater than the angle at two base angles.
In order to keep temperature in tower body 1, in the coil pipe that the also settable circular tower body 1 of 1 outer wall of tower body is arranged, by coil pipe
Inside being passed through hot water keeps constant 1 temperature of tower body.
It is worth noting that tower body 1 is provided with feed inlet close to top for entering high molecular weight reactive raw material in tower body 1
12 for various raw materials or other gases (such as nitrogen) for being passed through in tower body 1.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or

(22) distance in the vertical direction is 400-600mm;
The diameter of the main jet port is 30-35mm, and the diameter of the side spray port is 15-19mm;
One end of the air flue (31) is connected to steam steam line, so that extraneous steam enters the air flue (31), is most passed through afterwards
The main jet port and the side spray port spray into the tower body (1)；
Relief valve is set on the side wall of tower body (1)；
It is arranged on the side wall of tower body (1) hollow interlayer (4), the hollow interlayer (4) passes through through-hole (41) and the tower body
(1) the internal space connection for reaction;
The angle formed between the main channel (32) and horizontal plane is 3-4 °, main channel (32) horizontal extension, the side
Channel (33) is inclined on the side wall of the main channel (32), the central axes and the main channel of the wing passage (33)
(32) angle that central axes are formed is 8-15 °;
The diameter of the main channel (32) becomes larger from one end of main jet port towards the one end connecting with the air flue (31),
The diameter of one end that the main channel (32) connect with the air flue (31) is 1.30-1.40 times of the main jet port diameter；
Along in two blades (22) adjacent on the shaft (21) vertical axis, positioned at the blade (22) of lower
On the main jet port and the side spray port diameter be positioned at eminence the blade (22) on the main jet port
With 1.1-1.2 times of the side spray port diameter；
Shape near the blade (22) of the tower body (1) bottom is arch, is had parallel with the shaft (21) axis
Vertical spout；The diameter of the vertical spout is 50-80mm；
Two blades (22) in left and right, blade (22) described in side are connected at sustained height position, on the shaft (21)
On the wing passage (33) tilt down extension, the wing passage (33) on blade described in the other side (22) upwards inclination prolongs
It stretches；
Limited valve is arranged in the other end of the air flue (31).
