Abstract

The utility model discloses a negative pressure burner through improving furnace's structure, and burner inner tube and burner urceolus leave a slit, and wind passes through tuber pipe, whirlwind water conservancy diversion piece, then spouts from the slit high speed, because higher wind speed can form an intangible class vacuum region in high temperature resistant burner the place ahead, and the existence of this vacuum region can make furnace's the high-speed blowout of fire. Through the structure of improving furnace, burner inner tube and burner urceolus leave a slit, and wind passes through tuber pipe, whirlwind water conservancy diversion piece, then spouts from the slit high speed, because higher wind speed can form an intangible class vacuum region in high temperature resistant burner the place ahead, and the existence of this vacuum region can make the high-speed blowout of furnace's fire.

Negative pressure nozzle

Technical Field

The utility model relates to a fire burning furnace technical field, specifically be a negative pressure burner.

Background

A combustion furnace and an electric arc combustion furnace, also called a carbon-sulfur combustion furnace, are called electric arc furnaces for short, and utilize a high-voltage and high-frequency oscillation circuit to form an instantaneous large current to ignite a sample, so that mixed gas generated after the sample is rapidly combusted under an oxygen-enriched condition is subjected to a chemical analysis program to quantitatively and rapidly analyze the content of carbon and sulfur in the sample, and the physical and chemical workers in China perform crystallization in a long-term and hard work.

Due to the structural limitation of the hearth of the existing combustion furnace, the flame injection speed of the hearth is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a negative pressure burner, through improving furnace's structure, a slit is left to burner inner tube and burner urceolus, and wind passes through tuber pipe, whirlwind water conservancy diversion piece, then from the high-speed blowout of slit, because higher wind speed, can form an intangible class vacuum region in high temperature resistant burner the place ahead, and the existence of this vacuum region can make furnace's the high-speed blowout of fire, can solve the problem among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a negative pressure nozzle, includes nozzle inner tube, nozzle urceolus, high temperature resistant nozzle, tuber pipe and whirlwind water conservancy diversion piece, nozzle urceolus cover is on the nozzle inner tube, the upper end and the lower extreme of nozzle urceolus all set up the tuber pipe, the partial surface that the nozzle inner tube is located the nozzle urceolus has seted up high temperature resistant nozzle, and the partial surface that the nozzle inner tube is located the nozzle urceolus still distributes and has the whirlwind water conservancy diversion piece.

Preferably, one of the air pipes is an air inlet pipe, and the other air pipe is an air outlet pipe.

Preferably, the included angle between the cyclone flow deflector and the central line of the inner cylinder of the fire nozzle is 12 degrees.

Preferably, the cyclone guide vanes are circularly and equally distributed on the surface of the inner cylinder of the fire nozzle.

Preferably, the outer burner barrel is axisymmetrical with the center line of the inner burner barrel.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a negative pressure burner through improving furnace's structure, and burner inner tube and burner urceolus leave a slit, and wind passes through tuber pipe, whirlwind water conservancy diversion piece, then from the high-speed blowout of slit, because higher wind speed, can form an intangible class vacuum region in high temperature resistant burner the place ahead, and the existence of this vacuum region can make furnace's the high-speed blowout of fire.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a negative pressure burner comprises a burner inner cylinder 1, a burner outer cylinder 2, a high temperature resistant burner 3, an air pipe 4 and a cyclone flow deflector 5, wherein the burner outer cylinder 2 is sleeved on the burner inner cylinder 1, the burner outer cylinder 2 is axisymmetric with the center line of the burner inner cylinder 1 to ensure that the air directions are crossed in front of the burner to form a vacuum area, a small gap is reserved between the burner inner cylinder 1 and the burner outer cylinder 2, the upper end and the lower end of the burner outer cylinder 2 are both provided with the air pipe 4, the part of the surface of the burner inner cylinder 1 in the burner outer cylinder 2 is provided with the high temperature resistant burner 3, the part of the surface of the burner inner cylinder 1 in the burner outer cylinder 2 is also distributed with the cyclone flow deflector 5, and air passes through the air pipe 4 and the cyclone flow deflector 5 to be ejected from the small gap at a high speed, and can form an intangible vacuum area in front of the high temperature resistant burner 3 due to high air speed, causing the fire in the furnace to be ejected at a high rate.

One of the air pipes 4 is an air inlet pipe, and the other air pipe 4 is an air outlet pipe, so that the normal air can be kept.

The included angle between the cyclone flow deflectors 5 and the central line of the inner burner barrel 1 is 12 degrees, the cyclone flow deflectors 5 are distributed on the surface of the inner burner barrel 1 in a circular and equal way, and the effect of high-speed fire spraying is improved.

To sum up, the utility model discloses a negative pressure burner through improving furnace's structure, and burner inner tube 1 and burner urceolus 2 leave a slit, and wind passes through tuber pipe 4, whirlwind water conservancy diversion piece 5, then spouts from the slit high speed, because higher wind speed can form an intangible class vacuum region in 3 the place ahead of high temperature resistant burner, and the existence of this vacuum region can make furnace's the high-speed blowout of fire.
