Abstract
The utility model relates to a multichannel nozzle of a rotary kiln, which is capable of burning by mixing gas and pulverized coal or singly burning by the pulverized coal and used for kiln furnace industry. The multichannel nozzle of the rotary kiln comprises a central pipeline, a clean air pipeline, a pulverized coal pipeline, a gas pipeline and air teeth, wherein the central pipeline consists of a main unit, a conical portion and a tail, the main unit is in nest connection with the clean air pipeline, the tail of the clean air pipeline is hermetically welded with the main unit, the pulverized coal pipeline is mounted at the rear end of the main unit, the gas pipeline is mounted on the conical portion, and an angle formed by the pulverized coal pipe and the main unit ranges from 10 degrees to 30 degrees, an angle formed by the central line of the gas pipeline and the central line of the conical portion ranges from 10 degrees to 30 degrees, and the air teeth are mounted inside the front end of the main unit. The multichannel nozzle of the rotary kiln has the advantages that burning is more sufficient, flame temperature is higher, energy source is saved, and production capacity is improved.
Description
Technical field
The utility model relates to the industrial coal gas coal dust mixed combustion of a kind of kiln, or the rotary kiln multi-channel nozzle of the single burning of coal dust, is widely used in cement kiln and calcining kiln.
Background technology
In traditional kiln industrial product process procedure, what major part was used is the single channel coal nozzle, and the black duration and degree of heating of this nozzle is long, and efficiency of combustion is low, and flame profile, temperature can't regulate control, is difficult to satisfy current kiln calcination of chamotte good quality and high output, low energy consumption and environmental requirement.So three-channel nozzle occurred, this three-channel nozzle in use, the cooperation ratio of coal gas and coal dust is difficult to control, flame sprays in kiln and combustion zone length is not up to standard, to the requirement of ature of coal relatively strictness lead, the incomplete phenomenon of coal dust firing often appears in the kiln tail, thereby causes that the kiln tail gathers materials, windrow.Cause the scaling loss kliner coating, be unable to lift feeding capacity, the burner material existing problems that have are blown phenomenon easily, have both wasted the energy, have caused the very big pollution of environment again, cause product cost high.
The utility model content
In order to address the deficiencies of the prior art, the purpose of this utility model is to provide a kind of novel structure, low energy, and the coal gas that economic benefit is high, coal dust multifuel combustion rotary kiln multi-channel nozzle also can single combusting coal fines or the rotary kiln multi-channel nozzle of coal gas.
To achieve these goals, the technical scheme that the utility model adopted is: the rotary kiln multi-channel nozzle, by central tube, the clean wind pipe road, pulverized coal channel, gas piping and wind tooth are formed, central tube is by main part, tapered portion and afterbody are formed, main part and the socket of clean wind pipe road, and clean wind pipe road afterbody and main part welded seal, pulverized coal channel is installed in the main part rear end, tapered portion is installed gas piping, and the angle that pulverized coal channel and main part form is between 10 ℃ to 30 ℃, the angle that gas piping center line and tapered portion center line form is between 10 ℃ to 30 ℃, and the wind tooth is installed on main part front end inside.Operation principle process of the present utility model: adopt latest modern high speed difference and strong eddy flow theory, mix and match when high-pressure blast, coal gas and the coal dust in the central tube passes through diverse location in central tube, change the mixed gas and the coal dust direction of motion through the wind tooth, make and mix that back gas fully mixes with coal dust and pressure is more abundant, thereby prolongation burning zone, having high pressure draught in the clean wind pipe flows out, thereby guarantee that mist and coal dust that central tube flows out have more cohesion, make mist and coal dust firing more abundant.
The beneficial effects of the utility model are: burning zone extends to 8 meters to 10 meters by original 5 meters to 6 meters, and ignition temperature is increased to 1220 ℃ by 1180 ℃, and it is more abundant to burn, and flame temperature is higher; It is white that coal powder consumption drops to the 350kg/T section in vain by the 420kg/T section, energy savings; The white output of section increased to 190T/ days by 160T/ days, and production capacity is improved.
Description of drawings
Fig. 1 is the generalized section of a kind of rotary kiln multi-channel nozzle of the utility model.
Fig. 2 is the left view of a kind of rotary kiln multi-channel nozzle of the utility model.
Among the figure: rotary kiln multi-channel nozzle 10, central tube 11, clean wind pipe road 12, pulverized coal channel 13, gas piping 14, wind tooth 15, main part 111, tapered portion 112, afterbody 113
Specific embodiment
Rotary kiln multi-channel nozzle 10 is by central tube 11, clean wind pipe road 12, pulverized coal channel 13, gas piping 14 and wind tooth 15 are formed, central tube is by main part 111, tapered portion 112 is formed with afterbody 113, main part 111 and 12 sockets of clean wind pipe road, and clean wind pipe road 12 afterbodys and main part 111 welded seals, pulverized coal channel 13 is installed in main part 111 rear ends, tapered portion 112 is installed gas piping 14, and the angle that pulverized coal channel 13 and main part 111 form is between 10 ℃ to 30 ℃, the angle that gas piping 14 center lines and tapered portion 112 center lines form is between 10 ℃ to 30 ℃, and wind tooth 15 is installed on main part 111 front end inside.Operation principle process of the present utility model: adopt latest modern high speed difference and strong eddy flow theory, mix and match when high-pressure blast, coal gas and coal dust pass through diverse location in central tube 11, change the mixed gas and the coal dust direction of motion through wind tooth 15, make and mix that back gas fully mixes with coal dust and pressure is more abundant, thereby prolongation burning zone, having high pressure draught in the clean wind pipe road 12 flows out, thereby guarantee that mist and coal dust that central tube 11 flows out have more cohesion, make mist and coal dust firing more abundant.
