Description

swirl burner

technical field

The utility model relates to a swirl burner, which belongs to the technical field of tail gas treatment containing combustible gas.

Background technique

In the production process of organic chemical industry, petroleum refining industry, natural gas industry, metallurgical industry, etc., a large amount of toxic, harmful, flammable and explosive venting gas will be produced, which needs to be burned by the burner of the ground torch. One of the important factors in the combustion performance of a ground flare is the form of the burner. No treatment is done on the outlet of the existing tube burner. When the flow rate of the vented gas is high, the combustible gas forms a gas column at the outlet, which is not conducive to igniting the adjacent burner, and greatly shortens the arrangement distance of the burner, resulting in Insufficient air mixing of the combustible gas in the ground torch barrel caused the flame to stick together.

Utility model content

The utility model overcomes the deficiencies in the prior art, and the technical problem to be solved is to provide a burner with a swirl plate added at the outlet, which not only promotes the combustion of the gas, but also increases the ignition probability between the burners and improves the The ignition rate of the torch.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a swirl burner, including a main pipe, a branch pipe, an air mixing pipe and a swirl piece, the lower end of the main pipe is connected to the outlet of the exhaust pipe through a flange, and the main pipe There are multiple branch pipes in the middle, one end of the branch pipe communicates with the inside of the main pipe, and the other end of the branch pipe extends upwards, and a mixing pipe is fixedly installed at the outlet of the end, and a plurality of swirl vanes are evenly installed in the mixing pipe;

The swirl sheets are of folded plate structure, the lower ends of the plurality of swirl sheets are fixed on the inner wall of the air mixing pipe, and the upper ends of the plurality of swirl sheets protrude above the air mixing pipe in a form of swirling flow.

One side of the lower end of the swirl plate is fixedly connected to the outer wall of the outlet of the branch pipe, and the other side of the lower end is fixedly connected to the inner wall of the air mixing pipe.

Three swirl fins are uniformly installed on the inner wall of the air mixing pipe.

The swirl sheet is made by bending a heat-resistant stainless steel plate.

Compared with the prior art, the utility model has the beneficial effects that: the utility model adds a plurality of swirl sheets in the form of swirl above the outlet of the air-mixing air mixing pipe, so that the combustible gas at the outlet of the branch pipeline is effectively Scatter, play the role of swirl, increase the mixing area of combustible gas and air, promote the combustion of gas, increase the ignition probability between burners, and improve the ignition rate and burning rate of the torch; swirl The lower end of the sheet can also be used as a connecting rib to connect the branch pipe and the air mixing pipe, thereby reducing the cost.

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a physical diagram of the internal structure of the medium-mixing air duct of the present invention.

FIG. 3 is a top view of FIG. 2 .

In the figure: 1 is the main pipe, 2 is the branch pipe, 3 is the air mixing pipe, 4 is the swirl plate, and 5 is the flange.

Detailed ways

As shown in Figure 1-3, the swirl burner of the utility model includes a main pipe 1, a branch pipe 2, an air mixing pipe 3 and a swirl plate 4, the lower end of the main pipe 1 is connected to the outlet of the exhaust pipe through a flange 5, and the main pipe The middle part of 1 is provided with a plurality of branch pipes 2, one end of the branch pipe 2 communicates with the main pipe 1 and the other end extends upwards, and a mixing pipe 3 is fixedly installed at the outlet of the end, and the air mixing pipe 3 is uniformly installed There are multiple swirl fins 4;

The swirl sheet 4 is a folded plate structure, the lower ends of the plurality of swirl sheets 4 are fixed on the inner wall of the air mixing pipe 3, and the upper ends of the plurality of swirl sheets 4 protrude above the air mixing pipe 3 and form a swirling flow. form.

One side of the lower end of the swirl plate 4 is fixedly connected to the outer wall of the outlet of the branch pipe 2 and the other side of the lower end is fixedly connected to the inner wall of the air mixing pipe 3 .

Three swirl fins 4 are uniformly installed on the inner wall of the air mixing pipe 3 .

The swirl sheet 4 is made by bending a heat-resistant stainless steel plate.

The utility model is used in the technical fields containing combustible gas tail gas treatment such as organic chemical industry, petroleum refining industry, natural gas industry and metallurgical industry.

The exhaust gas is distributed to each branch pipe 2 through the main pipe 1, and then enters each air mixing pipe 3. The air mixing pipe 3 injects air to make the exhaust gas and air mix and burn, and at the same time play the role of wind protection. The swirl at the upper end of the swirl plate 4 The form is used to change the direction of the gas outlet, increase the contact surface between the combustible gas and the air, effectively disperse the combustible gas, and play the role of swirling flow.

The swirl sheet in the utility model has the following functions:

1. Increase the mixing area of combustible gas and air to promote the combustion of gas;

2. The ignition probability of the gas combustion port is increased, and the ignition rate of the torch is improved;

3. In terms of the combustibility of the entire torch, the burning rate of the torch is increased and the adhesion of the flame is reduced;

4. The lower end of the swirl plate is connected to the branch pipe and the air mixing pipe, which plays the role of connecting the rib plate and reduces the cost.
