Four-way gas central burner

Abstract

The utility model relates to a four-way gas central burner, which is composed of a core pipe, a gas passage, a primary air passage, a swirling flow sheet, etc. The exterior of the core pipe is orderly sheathed with four layers of sleeve pipes, wherein, the shapes of which are similar to the core pipe, and four annular passages are formed and are respectively a strong swirling flow passage (6) of the gas, a weak swirling flow passage (7) of the gas, a strong swirling flow passage (8) of the primary air, and a high-speed direct flowing passage (9) of the primary air. The four layers of sleeve pipes on the exterior of the core pipe is connected with telescopic corrugate pipes, and are provided with adjusting screws which can adjust the length of each sleeve pipe. The utility model is suitable for coke oven gas, converter gas with high heat value, and mixed gas of a blast furnace and a coke oven. An adjusting device is provided to adjust the cross section of each annular nozzle on the head of the burner, the required temperature field of the roasting technology can be ensured, the heat-transfer capability in a kiln can be raised, and the yield can be raised.

Description

Four-way coal gas central authorities burn and chew
Technical field
The utility model relates to a kind of coal gas burning to be chewed, and is that a kind of burning that is used for iron ore concentrate acid pellet calcination rotary kiln and clinker calcination rotary kiln is chewed.
Background technology
Traditional coal gas central authorities burn to chew and are binary channels, and gas passage and an air channel are set from inside to outside.This binary channels is burnt and is chewed, and primary air flow is bigger, reaches 10～15%, and flame profile is irregular, and it is unfavorable that rotary kiln is conducted heat, and the shortcoming of sweeping kliner coating is arranged, and influences kiln lining service life.
Summary of the invention
The purpose of this utility model is will provide a kind of to have the four-way coal gas central authorities burning of strong eddy flow, weak eddy flow gas passage and strong eddy flow, a wind passage of direct current to chew.
Utility model is achieved in that outside the core barrel that burning is chewed, and is provided with four circular passages.The adjusting device that can regulate head annular jet section is housed at the passage afterbody.
The utility model is applicable to the coal gas of converter and the blast furnace coke oven mixed gas of coke-stove gas, high heating value.There is adjusting device that burning is chewed each annular jet section of head and regulates, can realize burning the adjusting of chewing flame diameter and length, can guarantee the temperature field that roasting technique needs, improve heat-transfer capability in the kiln, improve output.And can prevent to produce iron ore concentrate acid pellet calcination rotary kiln ring formation, prolong kiln lining service life.Four-way burns the primary air flow chew and has only 7～10%, thus improved secondary high temperature wind go into kiln amount, the heat that can effectively utilize the high temperature chamotte cooling to discharge, energy savings.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Introduce the utility model below in conjunction with drawings and Examples.
With reference to accompanying drawing, one radical center pipe 12 is arranged, head is tubaeform, it is outer to overlap 4 layers successively and is being the sleeve pipe of similar figures with core barrel, form 4 circular passages 4, be respectively the strong eddy flow passage of the weak eddy flow passage of the strong eddy flow passage 6 of coal gas, coal gas 7, wind 8, a wind high speed direct current channel 9, chew head 1, form 4 horn-like or taper annular jets 2 in burning.The adjusting device 5 that is connecting on 4 layers of sleeve pipe outside the core barrel is with telescopic bellows 11, forms with adjusting screw(rod) 10, can suitably regulate the length of every sleeve pipe, make and produce axial displacement between adjacent casing, thus the section of change annular jet 2, with control coal gas and a wind flow.Near burning between the sleeve pipe of chewing head spinning disk 3 is being housed.
