Description
Technical Field
The invention belongs to the technical field of pressure vessels, and particularly relates to a high-efficiency gas distributor and a vertical large-scale reactor.
Background
Along with the development of economy and the progress of scientific technology in China, chemical equipment tends to be large-sized more and more, and various chemical reactors are more and more. The increased capacity of the device means increased flow, and for a reactor with gas inlet materials and non-distributed central area, the gas inlet connecting pipes are axially arranged at the center of the reactor, and high-flow-rate gas enters the reactor through the gas inlet connecting pipes and directly impacts a tube plate area without distributed tubes, so that the impact on the tube plate is not beneficial to the safety of the device. Meanwhile, uneven gas velocity distribution can occur in a cavity at the upper end of the reactor, so that the reaction efficiency is affected on one hand; on the other hand, gas vortex can be caused in the cavity, and the safety of equipment is endangered. The more uniform the gas distribution, the more favorable the stable progress and heat release of chemical reaction, and the higher the equipment reliability. The addition of a gas distributor at the lower end of the gas inlet enhances the uniform distribution of the gas. On the premise of continuously enlarging the reactor, the novel gas distributor structural design also needs to keep pace.
The traditional reactor gas distributor is generally a regular cone column or a reverse cone column, and holes are formed in the cone surface to strengthen gas distribution; there are also chinese patents which designed gas distributors with guide vanes, which utilize differential gas pressure to drive gas to be spirally distributed, so as to improve the uniformity of gas distribution at the inlet. The gas distributors have good application effect in small-sized equipment, however, when the equipment is large in scale and size, the structure can only influence the gas distribution in a certain area by taking a gas inlet as a center, and even distribution can not be ensured at the edge of the equipment and the area close to a reaction tube. Thus, the structural optimization of the gas distributor also has a large lifting space.

The outer-layer guide plate 51 changes the speed direction of the gas which is split into the axial direction and the radial direction, so that the gas is distributed more uniformly in the outer edge area of the upper sealing head 2. The surface of the inner baffle 52 and the guide vanes 57 form a spiral flow path, and when the gas passes through the flow path, the gas can change the direction of the gas flow to generate radial force, and when the gas leaves the flow path, the gas continues to flow spirally. And, the inner layer guide plate 52 can shelter from the middle part of the tube plate 6, thereby reducing the impact on the tube plate 6. The gas is radially diffused along the inner-layer guide plate 52, the gas distribution in the upper space of the area where the tube plate 6 is not distributed is less, the safety of the reactor is facilitated, and the gas distribution in the upper seal head 2 can be more uniform due to the addition of the spiral gas flow in the tube plate 6 distribution area.
The diameter of the upper section of the outer guide plate 51 is smaller than the inner diameter of the air inlet connecting pipe 3, so that an airflow channel between the outer side of the outer guide plate 51 and the inner wall of the upper seal head 2 is ensured, and the air flow dead zone of the upper seal head 2 is reduced.

The external magnet 59 is connected to a power device via a gear or a belt or other transmission mechanism. When the power device drives the outer magnet 59 to rotate through the transmission mechanism, the inner magnet 58 also rotates, and thus the inner baffle 52 fixed to the inner magnet 58 also rotates synchronously. The greater the power of the external power device, the faster the inner baffle 52 rotates. When the reactant gas contacts the inner baffle plate 52 and the guide vanes 57, the gas starts to change direction, flows along the spiral flow channel formed, and after leaving the guide vanes 57, the reactant gas starts to be uniformly distributed in a spiral shape.

Working principle:
For a certain tubular reactor, the inlet reaction gas is a mixture of air and a certain substance. The reaction gas enters the adapter flange 4 along the upstream pipeline and then enters the inlet adapter 3. The gas distributor 5 is disposed directly below the gas inlet nipple 3. In this embodiment, since the outer layer baffle 51 is disposed in the air inlet pipe 3, the air in the air inlet pipe is divided into two paths, and one path flows through the cavity formed by the upper end enclosure 2 and the outer layer baffle 51. When the reaction gas flows along the axial direction until contacting the outer surface of the outer guide plate 51, the reaction gas starts to flow along the outer surface of the outer guide plate 51, after leaving the outer surface of the outer guide plate 51, the gas speed continues to be divided into two directions, and flows downwards along the axial direction and outwards along the radial direction, the reaction gas can move farther along the radial direction before entering the tube plate 6, and the gas dead zone of the upper seal head 2 is small. The other path of reaction gas flows between the cavity formed by the outer layer baffle 51 and the inner layer baffle 52. When the reactant gas contacts the inner baffle plate 52 and the guide vanes 57, the gas starts to change direction, flows along the spiral flow channel formed, and after leaving the guide vanes 57, the reactant gas starts to be uniformly distributed in a spiral shape. When the outer magnet 59 is rotated by external power, the inner magnet 58 is rotated, and the inner baffle 52 fixed to the inner magnet 58 is rotated synchronously. The greater the power of the external motive force, the faster the inner baffle 52 rotates. Meanwhile, the reaction gas cannot directly impact the tube plate 6, the gas flow in the upper space of the tube plate 6 in the non-tube distribution area is extremely slow, and the flow path of the gas is reduced. The gas distributor 5 of the invention ensures that the reaction gas is distributed more uniformly in the upper seal head 2 after entering the upper seal head 2.
When no external power is applied, the inner magnet 58 is fixed, and the inner baffle 52 and the guide vane 57 are fixed. A spiral channel is formed between the inner guide plate 52 and the spiral inner guide vane 57. When the reactant gas contacts the inner baffle plate 52 and the guide vanes 57, the gas starts to change direction, flows along the spiral flow channel formed, and after leaving the guide vanes 57, the reactant gas starts to be uniformly distributed in a spiral shape.

And, the inner layer guide plate 52 can shelter from the middle part of the tube plate 6, thereby reducing the impact on the tube plate 6. The gas is radially diffused along the inner-layer guide plate 52, the gas distribution in the upper space of the area where the tube plate 6 is not distributed is less, the safety of the reactor is facilitated, and the gas distribution in the upper seal head 2 can be more uniform due to the addition of the spiral gas flow in the tube plate 6 distribution area.
