Abstract
An energy-saving smoke-reducing dusting method for industry furnace (or kiln) includes blowing cold air into high-temp oxygen heater, heating it to 350-650 deg.C, delivering it to nozzles, spraying it into combustion box and flue, mixing with fume and full combustion under the action of cracking agent and high-temp oxygen. Its advantages are high effect on reducing smoke and dust and saving energy.
Description
The invention belongs to the technical field of environmental protection, and particularly relates to a smoke prevention, dust control and energy saving method for an industrial kiln.
The smoke dust and energy saving problem of the industrial kiln is always a big problem in China using coal as main fuel, the prior treatment method for smoke dust is basically adopted, namely the tail gas at the tail end of the kiln is treated by adopting wet method, dry method, semi-dry method or electrostatic dust removal technology, although the smoke dust is reduced, the method is laggard, the technology is old, and the smoke and dust removing effect is not good, the method for treating the generated smoke dust has the disadvantages of great difficulty, complex technology, high secondary investment, large power and material consumption and high operation cost, the generated acid mist gas has serious corrosion to fans, pipelines, chimneys and the like in operation, and the treatment methods cannot meet the national environmental protection emission requirements and can not achieve the purpose of radically treating the smoke dust.
The invention aims to improve the defects of the prior art and provides a smoke prevention, dust control and energy saving method for an industrial kiln, which adopts cracking combustion, high-temperature oxygen hot air combustion supporting, low investment and operation cost and good smoke prevention, dust control and energy saving effects.
The invention aims to realize the method for eliminating smoke, reducing dust and saving energy of the industrial kiln, and is characterized in that the method comprises the following steps;
a. sending cold air into a high-temperature oxygen heater for heating through a fan;
b. heating air to 350-650 ℃, and feeding the air into a high-temperature oxygen burner;
c. high-temperature oxygen hot air is fed into the hearth and the flue through the burner and is mixed with the flue gas to form mixed flue gas;
d. the mixed flue gas is fully combusted under the action of a cracking agent and high-temperature oxygen;
e. combustible materials in the flue gas are discharged from the flue after being completely combusted.
To further achieve the object of the present invention, it is also possible that the cracking agent used in the process is KJGCo9V30Pd15AI10。
Compared withthe prior art, the invention has the following remarkable characteristics and positive effects: the invention adopts the high-temperature oxygen heater for heating, utilizes the heat of the kiln to heat cold air to be more than 350-650 ℃, and sends high-temperature oxygen hot air into each part in the kiln to promote combustible substances to be further fully combusted and be completely combusted before entering a chimney, thereby ensuring that the chimney does not discharge black smoke and achieving the purposes of smoke abatement and energy saving; the cracking combustion agent is buried in the industrial kiln, the function of the cracking combustion agent is to improve the combustion reaction activity and strength of fuel, release high-energy heat, enable the fuel to be fully combusted, improve the combustion efficiency, save energy, and simultaneously, the cracking combustion agent does not produce black smoke, and the main reaction formula is as follows:
the method for eliminating smoke, reducing dust and saving energy of the industrial kiln and furnace of the invention is further explained in detail by combining the embodiment.
Example 1A smoke prevention, dust control and energy saving method for an industrial kilnThe high-temperature oxygen heater is arranged at the high-temperature part of the furnace bottom, the high-temperature oxygen heater can be a non-metal heater or a metal heater, the non-metal heater is practical in the embodiment, a cracking agent is placed in the hearth of the industrial kiln, and the cracking agent is KJGCo9V30Pd15AI10The cold air outside the furnace is sent into a high-temperature oxygen heater by a fan to be heated,and the air is dischargedThe method comprises the following steps of heating gas to 450 ℃, feeding the gas into a high-temperature oxygen burner, feeding high-temperature oxygen hot air into a hearth and a flue from the high-temperature oxygen burner to be mixed with flue gas to form mixed flue gas, fully burning the mixed flue gas under the action of a cracking agent and high-temperature oxygen, discharging combustible substances in the mixed flue gas from the flue after the combustible substances are completely burned, and improving the burning reaction speed and reaction activity of the cracking agent in the burning reaction.
