Description

Technical Field

[0001] The utility model relates to the technical field of gas mixers, in particular to a gas mixer with uniform mixing. Background Technique

[0002] In the process of industrial production, production by-products are usually generated, and waste gas is the main product. When treating waste gas, for the combustible substances in the waste gas, the waste gas is mainly discharged into the combustion chamber and ignited, and the waste gas containing components such as formaldehyde gas and acidic catalysts is removed completely by high-temperature incineration. The gas mixer is an important device in the treatment of combustible waste gas. Due to the insufficient oxygen content in the waste gas, if there is no additional waste gas entering the combustion chamber, it will be difficult to burn and effective purification treatment cannot be obtained. Therefore, at the outlet of the waste gas treatment device, a gas mixer needs to be equipped to provide combustion conditions and ensure sufficient gas combustion.

[0003] Traditional gas mixers mostly adopt the mixing method of mixed flow inlet. The introduced gas is mixed by flow diffusion, and the mixing efficiency is low. The gas mixture flowing out of the mixer is not well mixed uniformly. During subsequent combustion, the combustible components in the waste gas are difficult to burn fully, which will reduce the purification treatment quality of the waste gas. Therefore, a gas mixer with uniform mixing is proposed. Content of the Utility Model

An air - guiding cavity 7 is arranged between the outer wall sandwich layers of the mixing cylinder base 1. The intake end pipe 4 is fixedly connected and installed with the outer side of the air - guiding cavity 7. To facilitate the hoisting and movement of the mixing cylinder base 1, lifting lugs 12 are uniformly arranged on the upper part of the mixing cylinder base 1.

[0025] In order to improve the uniformity of oxygen introduction and mixing, as shown in the appendix Figure 2 As shown, at the lower inner part of the mixing cylinder base 1, intake nozzles 8 are evenly arranged in a circumferential shape. Specifically, as shown in the appendix Figure 3 As shown, the intake nozzles 8 are evenly and fixedly connected and installed on the inner cylinder wall side of the mixing cylinder base 1 in a circumferential shape. In order to improve the gas mixing uniformity, the intake nozzles 8 are arranged in an inclined manner. The intake nozzles 8 are connected to the inner side of the air guide cavity 7, and oxygen can be evenly introduced into the interior of the mixing cylinder base 1. In order to improve the mixing uniformity, a spherical gas distribution cover 3 is installed at the end of the intake nozzles 8. As shown in the appendix Figure 5 As shown, the spherical gas distribution cover 3 is in the shape of a spherical cover. The spherical surface side of the spherical gas distribution cover 3 is evenly penetrated with shunt holes. The intake end of the spherical gas distribution cover 3 is connected and installed to the end of the intake nozzles 8 by threads. The shunt of the spherical gas distribution cover 3 can make the oxygen diffuse evenly, enabling the oxygen to mix more quickly and evenly with the waste gas introduced, and further improving the gas mixing uniformity.

[0026] The mixing mesh core 2 is arranged in a mesh core structure. The mixing mesh core 2 is fitted and supported and installed at the upper inner part of the mixing cylinder base 1. Specifically, as shown in the appendix Figure 3 As shown, in order to facilitate the installation and support of the mixing mesh core 2, a support ring seat 9 is fixedly installed inside the upper side of the mixing cylinder base 1. The mixing mesh core 2 is supported and fixedly fitted and installed inside the mixing cylinder base 1 through the support ring seat 9. After installation, the side surface of the mixing mesh core 2 is closely attached to the inner wall of the mixing cylinder base 1. In order to improve the gas mixing uniformity, as shown in the appendix Figure 4 As shown, corrugated-like mixing mesh holes are evenly arranged in the middle of the mixing mesh core 2.

[0027] In order to achieve secondary mixing, as shown in the appendix Figure 3 As shown, a mixing cavity is arranged in the middle of the mixing mesh core 2. The mixing cavity is arranged in the middle of the mixing mesh core 2. The outer side of the mixing cavity is evenly provided with connecting notches 11. In order to achieve secondary oxygen supply, as shown in the appendix Figure 5As shown in the figure, annular side air inlet holes 10 are uniformly arranged on the upper inner side of the mixing cylinder base 1. The annular side air inlet holes 10 are uniformly and circumferentially formed through the upper inner wall side of the mixing cylinder base 1. The annular side air inlet holes 10 are connected to the inner wall side of the air guide cavity 7. The annular side air inlet holes 10 are connected to the mixing cavity through the communication slots 11. A double-stage segmented mixing structure is adopted. In the first-stage mixing, oxygen is introduced into the mixing cylinder base 1 through the air inlet nozzles 8 uniformly arranged in a circumferential shape at the lower part of the mixing cylinder base 1, so that the oxygen is mixed with the waste gas entering the mixing cylinder base 1 in the first stage. Then, in the mixing mesh core 2, the mixed gas is subjected to secondary mixing by the mixing mesh core 2 with corrugated mesh holes, and secondary oxygen supplementation is carried out through the annular side air inlet holes 10. The second-stage mixing of the gas is completed in the mixing mesh core 2, which can effectively increase the mixing uniformity of the waste gas and oxygen, make the combustion purification of the waste gas more thorough, and is conducive to improving the waste gas purification quality. In order to install and protect the side of the communication slot 11, as shown in the appendix Figure 4 As shown in the figure, a protective mesh cover is arranged on the opening side of the communication slot 11.

[0028] During operation, oxygen enters the air guide cavity 7 from the intake end pipe 4, and then is respectively shunted and enters the mixing cylinder base 1 from the air inlet nozzles 8 and the annular side air inlet holes 10. At the same time, the external waste gas enters through the air inlet port 5 at the lower part of the mixing cylinder base 1, and is uniformly mixed with the oxygen dispersed and guided by the spherical gas distribution cover 3 at the lower inner side of the mixing cylinder base 1. Then, the mixed gas moves upward to the mixing mesh core 2, and is dispersed and mixed through the corrugated mesh hole structure in the mixing mesh core 2. At the same time, it is secondarily mixed with the oxygen discharged from the annular side air inlet holes 10 in the cavity in the middle of the mixing mesh core 2. Then, the mixed gas passes through the corrugated mesh hole structure at the upper part of the mixing mesh core 2 again to be further mixed evenly. Then, the mixed gas is discharged from the air outlet port 6 at the upper part of the mixing cylinder base 1 and enters the combustion chamber for full combustion, completing the combustion purification of the waste gas.

[0029] In summary, this gas mixer adopts a double-stage segmented mixing structure. In the first-stage mixing, oxygen is introduced into the mixing cylinder base 1 through the air inlet nozzles 8 uniformly arranged in a circumferential shape at the lower part of the mixing cylinder base 1, so that the oxygen is mixed with the waste gas entering the mixing cylinder base 1 in the first stage. Then, in the mixing mesh core 2, the mixed gas is subjected to secondary mixing by the mixing mesh core 2 with corrugated mesh holes, and secondary oxygen supplementation is carried out through the annular side air inlet holes 10. The second-stage mixing of the gas is completed in the mixing mesh core 2, which can effectively increase the mixing uniformity of the waste gas and oxygen, make the combustion purification of the waste gas more thorough, and is conducive to improving the waste gas purification quality. And a spherical gas distribution cover 3 is installed at the air outlet end of the air inlet nozzle 8.
