Abstract

The solution relates to a reactor and built-in a mechanical debris separator a of the filler material and the gas stream. The essence is that in the bottom part of the reactor is a variable channel flow cross-section and built-in virnikem, which opens into a sink with separation day. The space above the partition is connected to the outlet and the space below the separating bottom opens into the throat of the separated outflow particles.

Description

BACKGROUND OF THE INVENTION The present invention relates to a reactor with a built-in separator of mechanical debris and dust from the gas stream.

The prior art devices for the same purpose are designed in the form of filters and sieves, which are usually located outside the reactor body itself. This placement is necessary because the screens and filters are clogged during operation. This is also a major drawback of these embodiments. Filters and sutures must be replaced or cleaned. This requires their decommissioning. Placing the filters and sieves in a bypass outside the reactor itself allows the reactor or the filter or sieve not to be decommissioned. Such an embodiment, however, increases investment costs and operating costs, and often such devices are a source of high pressure losses and downtime. In addition, some filler materials are pyrophoric, making the applicability of such separators even more difficult.

It is therefore proposed to provide an improved reactor with a built-in separator having the above-mentioned disadvantages from. Essence of

No. 263,002 of the invention is that a channel having a variable flow cross-section and a built-in gyroplane is installed in the lower part of the reactor and flows into a well with a separating bottom. The space above the separating bottom is connected to the outlet throat, while the space below the separating bottom opens into the neck of the separated particles. Create channel with variable cross-section, corrugated pipe and sump with separating bottom! built-in separator.

The gas flowing in the reactor during operation carries with it a part of the filler mass _w , or possibly lining particles, etc., which are separated after passing through the built-in separator! from the gas flow to the space below the separating bottom, from where they are discharged through the neck of the separated particles. Clean gas is discharged through the outlet. In some reactors, the packing material needs to be regenerated or purged with gas upstream of the process medium. In this case, the channel with variable cross-section together with the vortex serves as a gas distributor to distribute the gas evenly over the cross-section of the filling material. The built-in separator does not increase its pressure drop during operation.

An exemplary embodiment of a reactor with a built-in separator is shown schematically in the attached drawing, which is a vertical section through the bottom of the reactor.

The reactor 1 provided with a lining 4 and filled with catalyst 3 has a separator formed in its lower part 2 'formed by a channel 5 with a variable cross-section with a built-in gyroplane 6 at its lower end through a discharge sleeve C into a separator bottom 7. 9 is connected to the outlet orifice 10 and the space below the separating bottom orifice 6 to the orifice 11, the withdrawal of the separated particles.

~ ° 283 002

The operating medium carrying the catalyst particles and linings flowing through the reactor 1 through the catalyst 3 enters a variable cross-sectional channel, where a part of its compressive energy is transformed into motional energy and the accelerated flow is rotated by the gyroplane 6. As a result of centrifugal forces and a change in the direction of flow upon entry of the process medium into the well 7, the mechanical particles are separated from the process medium stream and collected under the separating bottom 9. The separating bottom 9 prevents the particles from swirling and entrained. The separated particles are discharged through the orifice 11. The sleeve 8 dampens the channel vibrations

5. The working medium devoid of mechanical particles exits the reactor 1 through the outlet orifice 10.

During the regeneration of the catalyst 3, the gas for regeneration through the outlet throat 10 is introduced into the reactor 1. In this case, the channel 5 has the function of a diffuser, changes some of the movement energy into pressure energy and ensures uniform distribution of the regeneration gas stream along the reactor cross section.
