Description
Technical field
The utility model relates to technical fields such as metallurgy and building materials, relates to the rotary kiln that a kind of rotary kiln body is provided with the temperature measurement on-line device specifically.
Background technology
At present, at carbon industry, rotary kiln is most widely used calciner, and back Jiao that forges of about in the world 85% produces with calcining refinery coke by rotary kiln at present.Rotary kiln comprises calcining kiln and cooling kiln, and it not only has the characteristics that production capacity greatly, easily realizes mechanization, automation; Also have characteristics such as fuel consumption is little, refractory material is easy to wear and come off simultaneously.
The length of the rotary kiln of prior art is generally at 20-70m, and diameter 1-3.5m can move in kiln in order to make material, and the kiln body will tilt to install, and inclined height is generally the 2-5% of kiln body length overall.The general 0.75-2.5r/min of the rotating speed of kiln body.The time that raw material stops in kiln is 30-90min, coke is in the time of the stop of burning zone, can adjust according to the difference of temperature, burning zone can be divided into three intervals: first section is dry materials and preheating zone, and temperature end is 800-1100 ℃, feed end is 500-600 ℃, second section: be burning zone, length is 8-12m, and temperature is 1200-1450 ℃, the 3rd section: be salband, length is 1.5-2m.Filling rate is 3-15%.During ordinary production, negative pressure can not be excessive in the kiln, and is excessive, and powder is siphoned away too much, cause casting yield to descend, flame is elongated, and the heat force intensity of combustion zone and temperature reduce, the fugitive constituent incomplete combustion, be inhaled into the flue burning, cause EGT too high, not only thermal loss, and easy burn-out fume extractor.
The measurement of the calcined by rotary kiln band temperature of prior art, measure the temperature of burning zone mostly with infrared radiation thermometer, because the calcining belt temperature of front can produce the back burning zone and disturb, so, this method, in fact can't measure the temperature of each section of burning zone, experienced master craftsman also can only be with feeling, by rule of thumb the temperature of each section of burning zone being controlled.And the design of designing institute only designs the thermocouple of measuring kiln hood and kiln end temperature usually, because rotary kiln rotates, temperature signal can't be guided on the DCS with lead.This is the present calcination rotary kiln present situation of China.
And it is stable that calcined petroleum coke is shunk, and molecules align is neat, and product is qualified, and carbon raw materials oxidization burning loss rate is low, controls the temperature of burning zone accurately, and is most important.
If calcining heat is low excessively, carbon raw materials can not get abundant contraction, and its pyrolysis and polycondensation reaction are not enough, and then carbon product is in the process of roasting, and fugitive constituent is too high, will excessive contraction take place, so that cause product distortion or fracture.So raw material must be through calcining discharge fugitive constituent wherein.
If calcining heat is too high, it is big that carbon raw materials oxidization burning loss rate becomes, (Chinese charcoal ink factory carbonaceous burn out rate is generally 10-12%), then carbon product is in the process of roasting, and shrinkage factor is little, and its contraction only depends on binding agent to provide, to make goods loose, bulk density and mechanical strength are low.
Summary of the invention
The purpose of this utility model designs the rotary kiln that a kind of rotary kiln body is provided with the temperature measurement on-line device at existing weak point in the above-mentioned prior art just.This rotary kiln sends the temperature signal of each section of burning zone to intelligent radio input terminal (TY105H-2) by the temperature measurement on-line element with wireless transmission method, and TY105H-2 sends signal to intelligent radio outlet terminal (TY105H-3) TY105H-3 output precise dose signal (4-20mA) to DCS by wireless mode.
The purpose of this utility model can realize by following technical measures:
The rotary kiln that rotary kiln body of the present utility model is provided with the temperature measurement on-line device comprises the rotary kiln of being made up of calcining kiln and cooling kiln; Wherein the axis direction along calcining kiln rotary kiln body is equipped with the temperature measurement on-line element that a plurality of employing wireless transmission methods transmit each section of burning zone temperature.
The element of temperature measurement on-line described in the utility model is an infrared radiation thermometer, and described infrared radiation thermometer is installed in the installing hole that processes on the calcining kiln kiln wall by adpting flange, coolant jacket and interior sighting tube; Described temperature measurement on-line element also can adopt thermocouple, and described thermocouple is installed in the installing hole that processes on the calcining kiln kiln wall by adpting flange.
More specifically say, infrared radiation thermometer described in the utility model or thermocouple temperature measurement element are on the straight line, the temperature signal of these online infrared radiation thermometers or thermocouple output 4-20mA, send intelligent radio input terminal (TY105H-2) to, TY105H-2 sends signal to intelligent radio outlet terminal (TY105H-3) by wireless mode, and TY105H-3 output precise dose signal (4-20mA) is to DCS.Exact temperature measurement has been arranged, with PLC automatic control calcination system software kit, the air quantity of the amount by control air-introduced machine (negative pressure), blanking amount, fuel, the rotating speed of rotary kiln, wind, secondary wind, tertiary air, four wind, five wind just can accurately be controlled the temperature of each section of burning zone.
Rotary kiln of the present utility model can accurately be measured the temperature of each section of calcined by rotary kiln band, and this is to realize that DCS controls the precondition of calcination system automatically, and it makes the temperature of accurate each section of control burning zone become possibility.The air quantity of the amount by control air-introduced machine (negative pressure), blanking amount, fuel, the rotating speed of rotary kiln, wind, secondary wind, tertiary air, four wind, five wind just can accurately be controlled the temperature of each section of burning zone.Because accurately the temperature of each section of control burning zone just can make the petroleum coke product quality of calcining better, qualification rate improves greatly, reduces burn out rate.In addition, rotary kiln of the present utility model not only can make the quality of product be greatly improved, and also can effectively reduce burn out rate simultaneously, alleviates working strength of workers, prolongs the service life of liner.
