Abstract
The utility model provides a novel apparatus for treating industrial organic waste gases, which is composed of a heat exchange section (1), a heating section (2), a conversion section (3), an air inlet pipe (7), a circulation pipe (8), an exhaust pipe (5), and an electrical heating element (9). Fibrous alumina or fibrous composite alumina is used as a carrier in the conversion section (3) for supporting fibrous catalysts made of active noble metal components. Compared with an apparatus for loading granular catalysts, under the same treatment condition, the volume of the utility model is reduced, and catalyst loading volume is smaller than the 10% of the granular catalysts; the utility model has the advantages of high purification efficiency, high stability, and long service life.
Description
The utility model belongs to a kind of catalytic combustion system, relates in particular to a kind of infant industry organic waste gas treatment device.
All discharge various organic exhaust gas such as benzene, toluene, ethanol, acetone at many industries such as chemical industry, oil, paint, printing, insulating materials, asbestos and internal combustion engine, combustion furnace etc., serious environment pollution, harm worker and resident's is healthy.Therefore the national environmental protection method has also been stipulated discharge standard to this, need the organic exhaust gas of discharging on the purified industrial, to reach discharge standard.
The method of the organic exhaust gas of discharging on the purified industrial is a lot, though reach the purpose that purifies air as direct firing method, generally will consume a large amount of electric power and fuel about 800 ℃.Production by Catalytic Combustion Process be a kind of under catalyst action the method for low-temperature burning, energy-conservation, consumption reduction, domestic extensive use, commercial plant is also arranged, but because of its catalyst is graininess, its carrier is natural zeolite or ceramic honey comb etc., is coated with stain metal oxide or rare earth, catalyst activity is lower, useful load is big, and service life is short, so device volume is than bulkiness.
It is little that the purpose of this utility model provides a kind of volume, the infant industry organic waste gas treatment device of long service life.
Goal of the invention of the present utility model is achieved in that this device bottom is a heat exchanging segment, and the middle part is a bringing-up section, and top is conversion zone.Device be provided with air inlet pipe bottom.One end of circulation pipe is communicated with the upper end of device, and the other end of circulation pipe is communicated with heat exchanging segment.Heat exchanging segment is provided with blast pipe.The effect of heat exchanging segment is the waste heat preheating organic exhaust gas that utilizes after burning, and energy savings, bringing-up section are to heat organic exhaust gas with heating element heater, make it to reach initiation temperature, are mainly used in the starting period of this device.In case in conversion zone, can reduce the heat that adds of bringing-up section behind the ignition.Be provided with screen in its conversion zone, be placed with the felt that fiber-like catalyst is made on the screen, or cotton-wool.
Fiber-like catalyst carrier described in the utility model is fibrous alumina or fibrous composite alumina, and it is formed and physical characteristic is:
Form: Al
2O
3Content 90-99.9%
Other (Si, Zr, Ti, Mg) content 0.1-10%
Rerum natura: specific surface 40-220m
2/ g average diameter 1-5 μ
Nature unit weight 0.03-0.1g/cm
3Fibrofelt draws strong 10-120N/mm
1100 ℃ of crystalline phase η-Al of maximum operation (service) temperature
2O
3Be main
Above carrier place mat is become felted or flocculence, put into the aqueous solution dipping active component of certain density Pt or Pd, Rh, Re, the back is dry, and roasting promptly gets this device catalyst system therefor, the contained precious metals pt of catalyst, Rh, Re etc., content 0.05-2.5%.
When organic exhaust gas is fed this device, be heated to the catalysis initiation temperature by the heating element heater of bringing-up section and enter conversion zone, under the effect of catalyst, the beginning catalytic combustion.Harmful pneumatolytic of organic exhaust gas divides is burnt, and the gas after the burning enters heat exchanging segment by circulation pipe, and the organic exhaust gas of preheating access to plant through after the heat exchange, can reduce the heat that adds of bringing-up section, and the gas after the burning is through circulation pipe, heat exchanging segment, blast pipe emptying.
The utility model compared with prior art has following advantage:
1. owing to used fibrous alumina or fibrous composite alumina to be carrier, support the fiber-like catalyst that the active noble metals component is made, the catalyst useful load dwindles the volume of device less than 10% of pellet type catalyst greatly under identical treating capacity condition.
2. long service life.
Embodiment accompanying drawings of the present utility model is as follows:
As shown in the figure, 1 is heat exchanging segment, and 2 is bringing-up section, and 3 is conversion zone, and 4 is screen, and 5 is blast pipe, and 6 is fiber-like catalyst, and 7 is air inlet pipe, and 8 is circulation pipe, and 9 is electric furnace heating wire (or electrical bar).
The bottom of device is a heat exchanging segment 1, the middle part is a bringing-up section 2, top is conversion zone 3, conversion zone 3 is fixed with screen, be placed with fiber-like catalyst 6 on the screen 4, there is air inlet pipe 7 the device lower end, and an end of circulation pipe 8 is communicated with the upper end of device, the other end of circulation pipe 3 is communicated with heat exchanging segment 1, also is provided with blast pipe 5 on the heat exchanger tube 1.
When organic waste gas enters this device through air inlet pipe 7, electric furnace heating wire in the section of being heated 2 (or electrical bar) 9 is heated to initiation temperature, carry out catalytic combustion by the fiber-like catalyst in the conversion zone 36, the harmful components of organic exhaust gas are burnt, gas after the burning enters heat exchanging segment by circulation pipe 8, but preheating through after the heat exchange, can reduce the heat that adds of bringing-up section 2 through the organic exhaust gas of air inlet pipe 7 accesss to plant.At last, the gas after the burning is through blast pipe 5 emptying.
