Description

Novel mixer

Technical Field

The utility model relates to a coal gas blender technical field especially relates to a novel blender.

Background

The existing gas mixer is easy to generate backflow when the pressure changes, and has no mixing effect when the pressure difference of a mixing pipeline is too large. In addition, the industrial gas has high water content, strong corrosivity and short service life of the mixer. Based on this, the utility model provides a novel blender not only is applicable to different calorific values, and the coal gas of different pressures mixes, through mixing branch pipe whirl blade, still can accelerate coal gas and mix increase of service life.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel blender solves the problem that branch coal gas does not mix or even flows back when pressure difference between the branch pipes is great.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model relates to a novel mixer, which comprises a shell, wherein a first branch pipe is arranged at the inlet end of the shell, a nozzle is arranged at the outlet end of the first branch pipe inside the shell, and a plurality of swirl vanes for supporting the first branch pipe are uniformly distributed on the outlet circumference of the nozzle; a second branch pipe is arranged at the inlet end of the side wall of the shell, and the second branch pipe is inclined relative to the first branch pipe; and gas enters the shell from the first branch pipe and the second branch pipe respectively, then passes through the swirl vanes and finally goes out from the outlet end of the shell.

Furthermore, the inclination angle of the two branch pipes relative to the first branch pipe is 0-90 degrees.

Further, the shell is made of corrosion-resistant materials.

Furthermore, the directions and the angles of a plurality of the swirl vanes are consistent.

Further, the swirl vanes are curved.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses a novel blender is under the condition that does not increase external facilities, and its inside whirl blade of adding can make rotatory air current cross, and when branch pipe pressure was less than another way branch pipe all the way promptly, branch pipe rotatory air current all the way can drive the air current of another way branch pipe, realizes the mixture of two way branch pipes. In a word, when this utility model novel blender can alleviate pressure differential between the branch pipe great, branch road coal gas does not mix the backward flow problem even, makes the coal gas mix the effect better.

Detailed Description

As shown in fig. 1 and 2, a novel mixer comprises a shell 2, wherein the shell 2 is made of corrosion-resistant material, such as 304 stainless steel. A first branch pipe 3 is installed at the inlet end of the shell 2, and the installation end of the first branch pipe 3 extends into the shell 2. And a nozzle 5 is arranged at the outlet end of the branch pipe I3 positioned in the shell 2, and the nozzle 5 can spray out the coal gas to be mixed. And a plurality of swirl blades 1 supporting the branch pipe I3 are uniformly distributed on the outlet circumference of the nozzle 5, the swirl blades 1 are in a curve shape, the directions and the angles of the plurality of swirl blades 1 are consistent, and the gas flow passes through the swirl blades 1 and rotates to be mixed with other branch pipe gas. And a second branch pipe 4 is arranged at the inlet end of the side wall of the shell 2, the second branch pipe 4 is inclined relative to the first branch pipe 3, and the inclination angle of the second branch pipe 4 relative to the first branch pipe 3 is 0-90 degrees. In this embodiment, when the pressure in the first branch pipe is lower than the pressure in the second branch pipe, the rotating airflow in the first branch pipe can drive the airflow in the second branch pipe, so that mixing is realized, and the problem that branch coal gas is not mixed or even flows back when the pressure difference between the branch pipes is large is effectively solved.

Gas (namely coal gas) enters the shell 2 from the first branch pipe 3 and the second branch pipe 4 respectively, and then the coal gas flows rotate through the swirl vanes 1 to realize mixing; and finally out of the outlet end of the housing 2.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
