Abstract
The invention discloses a multi-tube burner which is arranged in a rotary kiln body and comprises multiple air tubes arranged in parallel and gas tubes arranged in the air tubes or extended in the air tubes, wherein process support tubes are arranged among the multiple air tubes as well as between the air tubes and the kiln body, the outlet end of each gas tube is provided with a gas-air flow mixing mechanism, a flow mixing region is formed in the vicinity of the outlet end of the gas tube in the air tube, and the flow mixing region is provided with an ignition detection mechanism. By radially arranging multiple multi-tube burners in the kiln body along the inner side of the kiln wall towards the center line of the kiln, the invention has the following beneficial effect: the multi-tube burners and multiple rows of heating tubes effectively increase the area for heat transfer by contact and radiation of materials, thereby achieving high heat transfer efficiency.
Description
Technical field
The invention belongs to the burner apparatus technical field in the revolution body of heater, be specifically related to a kind of multiple-tubed burner.
Background technology
Current, rotary kiln device still is a kind of main equipment that must rely in the industrial production, in many production industries such as building materials, metallurgy, chemical industry, environmental protection, uses apparatus for rotating that solid material is carried out machinery, physical or chemical treatment widely.The rotary kiln body has a variety of mode of heatings, it also is wherein a kind of that burner wherein is set in the kiln body, burner on the kiln body has common, heat accumulating type, accumulation of heat is radioactive, but the burner that is arranged in the revolving body stove and be arranged in parallel with the stove axis, burning flame gas does not take place directly to contact with the interior heating object of kiln body, heat energy conducts, is radiated on the heating object by heating tube, realizes its multiple-tubed burner structure that heats is not also occurred.
Summary of the invention
The invention provides a kind ofly be used to being arranged in the rotary kiln body, to the multiple-tubed burner that many rows heating tube heats, multiple-tubed burner arranges along the kiln wall to the kiln center line, organize more multiple-tubed burner along the circumference radial arrangement in the kiln body.
A kind of multiple-tubed burner, be arranged in the rotary kiln body, comprise the many air hoses that be arranged in parallel and be arranged in the air hose or stretch into the interior Gas Pipe of air hose, between the described many air hoses, between air hose and the kiln body technology stay pipe is set, the port of export of described Gas Pipe arranges gas-air mixed flow mechanism, form mixed flow region near the port of export of the inherent Gas Pipe of described air hose, described mixed flow region arranges igniting testing agency.
The described Gas Pipe that stretches in the air hose stretches in the air hose by described technology stay pipe.
The igniting testing agency that described mixed flow region arranges, it is external to stretch out kiln by described technology stay pipe.
Sealing seam flange is set on the described technology stay pipe.
Since the invention provides a kind of be used to being arranged in the rotary kiln body, the multiple-tubed burner that many rows heating tube is heated.This multiple-tubed burner side direction kiln center line in the kiln wall is arranged, many group multiple-tubed burner radial arrangement are in the kiln body, its useful effect is: multiple-tubed burner and many row's heating tubes have effectively increased the area with material transmission of heat by contact and radiant heat transfer, heat transfer efficiency height; The setting of technology stay pipe makes the multiple-tubed burner strong fix, and fractionation and installation that sealing seam flange is conducive to multiple-tubed burner are set on the technology stay pipe; Multiple-tubed burner and many row's heating tubes also play the effect of dispersed with stirring material; Ignitor is conducive to automatic igniting; Flame testing agency is conducive in time find whether igniting is successful.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is that combustion gas of the present invention is from the overhanging structural representation of coming in of rotary kiln wall.
Fig. 2 is that combustion gas of the present invention puts in next structural representation from the rotary kiln head end.
