Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas treatment device that brings a powdered first substance and a gaseous second substance into contact, causes them to react with each other, and then removes the reactant.

In conventional gas treatment equipment, the removed reactants include:
It contains a large amount of unreacted primary substances, which are often discarded as is.

In addition, even if it is reused, problems such as blockage may occur due to inappropriate supply methods and locations of the mixed substance of unreacted first substance and reactant, so-called collection substance, which may hinder the smooth operation of the equipment. It may also cause problems.

In order to eliminate such drawbacks, the present invention provides a new gas processing apparatus equipped with a device capable of continuously supplying collected substances for reuse.

Next, it will be explained using figures.

Figure 1 shows a conventional gas treatment device, with main reaction section 2
and a secondary reaction section 4.

In FIG. 1, a powdered first substance is produced by transporting a fixed amount of the first substance from a first substance storage tank 11 through a rotary feeder 12 using compressed air sent by a blower 10. The second substance is supplied to the conduit 1 through the supply port 13 and flows into the main reaction section 2 together with the second substance.

Here, the speed of the mixed substance of the first substance and the second substance is reduced, and the mixed substance flows as shown by arrow 3, and the first substance and the second substance are in contact with each other and react with each other, forming a cyclone shape. Next, it flows into the reaction section 4.

Here, the mixed substance of the first substance and the second substance is in contact with each other and reacts with each other, forming a downward spiral flow, and the reactant and a certain portion of the unreacted first substance are separated, and then the conduit 6 The air passes through a high-performance dust collector 7 and a blower 8 before being released into the atmosphere from a chimney 9.

On the other hand, the mixed substance of the reactant and unreacted first substance collected in the secondary reaction section 4, so-called collected material, is passed through the rotary valve 5 to the upstream conduit 1 of the main reaction section 2 for reuse. supplied to

In this case, the collection material supplied to conduit 1 is sometimes
It may stay inside the body and block the tube.

Examples that can solve this blockage problem are shown in FIGS. 2, 3, and 4.

As shown in FIGS. 2, 3 and 4, the secondary reaction section 4
The collected substances are conveyed by a screw conveyor 14 in FIG. 2, by a chute 15 with a slope greater than the angle of repose in FIG. A method was adopted in which the compressed air sent through the main reaction section 2 was supplied to the upper part of the first substance supply port 13 at the lower part of the main reaction part 2 by gas transport.

By using these methods, it is possible to prevent blockage caused by the collected substances in the conduit 1, which was a problem with the conventional method shown in FIG. By arranging the shaped first substance diffusion cone 19, the air-transported first substance is entrained in the airflow of the second substance introduced through the conduit 1, and sufficient contact time and number of contacts can be obtained. Increase reaction rate.

Furthermore, even if the supply point of the first substance is the same as the supply port 13 in the conduit 1 on the upstream side of the main reaction section 2 shown in FIG. and the location shown in Figure 4,
In other words, it was confirmed that the performance and operation of the gas treatment apparatus would not be affected in any way if it was located at the lower part of the main reaction section 2.
