Abstract

PURPOSE:To generate a revolving stream for forming an optimum mixed stream, by attaching blades radially to provide blowoff part to the rotary shaft of the blade wheel provided in a conduit and blowing off a substance to be mixed such as gas, a liquid or a powder toward the revolving stream. CONSTITUTION:A large number of blades 2 are provided to the blowoff part 5 of a substance to be mixed provided in a conduit 1 so as to be expanded radially toward the outer peripheral direction of said blowoff part 5. These blades 2 can be freely changed in an angle by a blade driving apparatus 3 and adjusted so as to be capable of obtaining a most effective revolving stream corresponding to the quantity and quality of the substance to be mixed. A mixture reaches the mixture blowoff part 5 through a mixture blow-in pipe 4 and blown off therefrom to the gas flowing direction thereof. The blow-in pipe 4 is made simply detachable and the convenience of cleaning is considered. Further, the blades 2 are closely contacted to each other by operating the driving apparatus 3 of the blades 2 to enable the closing of the conduit 1.

Description

Detailed Description of the Invention: Industrial Applications Devices that perform adsorption and absorption reactions by spraying a mixture of gases, liquids, or solids onto gases or liquids flowing in flues, waterways, etc. are often used in industry. has been done. For example, it is a device that blows slaked lime into the flue of a garbage incinerator to remove chloride gas.

Conventional technology In the past, the mixture of gas, liquid or solid was directly blown into a conduit through which the liquid or gas to be mixed was flowing, which was ineffective, and another type of mixing device was installed to spray the mixture from the upstream side of the flow. There is then a risk that the reaction products will adhere to or stick to the equipment, causing a blockage and blocking the conduit. Furthermore, when the conduit is closed or not in use, it is necessary to provide a separate shielding valve, which is uneconomical.

Problems to be Solved by the Invention The present invention solves the problems of the prior art.

Means for solving the problem Rotation in a conduit with a square or round cross section, radially from the center to the outer circumference, and around an axis perpendicular to the flow. By mechanically or artificially changing the angle of these blades, it is possible to generate a swirling flow that creates the most thorough mixing situation between the mixture and the to-be-mixed mixture. . Further, the mixture is sprayed from a spray hole provided in the center of the conduit toward the rear of the flow of the mixture to prevent the mixture from adhering to the device. Furthermore, the mixing device is characterized by having a structure in which, by changing the angle of the blades described above, the blades overlap each other, thereby making it possible to close the conduit.

Effect: By taking the above-mentioned measures, the problems that the present invention seeks to solve can be solved.

EXAMPLE Next, details of the mixing apparatus according to the present invention will be explained with reference to the accompanying drawings.

FIG. 1 is a cross-sectional elevational view of the mixing device.

A large number of blades 2 are provided around a mixed object blowing part 5 provided in the conduit 1 and extending radially in the outer circumferential direction. The angle of these blades can be freely changed by a blade driving device 3, and the blades are adjusted so as to obtain the most effective swirling flow depending on the quantity and quality of the materials to be mixed.

Further, the mixture reaches the mixture blowing section 5 through the mixture blowing pipe 4, and is blown out from this portion in the direction of gas flow of the mixture.

Further, the blowing pipe 4 is made easily removable for convenience such as cleaning. Further, the blades 2 can be operated by the driving device @3 to bring the blades 2 into close contact with each other and close the conduit 1.
