The decontamination plant has the advantages of simple structure, scientific and reasonable design and high safety and reliability; by the adoption of the decontamination plant, the contact time of organic pollutants and catalysts can be increased effectively, the overall temperature evenness of a catalyst bed can be improved; therefore, the high-efficiency catalytic combustion decontamination plant is capable of improving the decontamination rate of the industrial volatilizable organic pollutants.
Description
Technical field
The invention belongs to the purifier field, the volatilizable organic pollution efficient catalytic of especially a kind of industry combustion purification device.
Background technology
It is the characteristic of utilizing the pollutant incendivity oxidation in the waste gas that catalytic combustion purifies, become its burning harmless or be easy to further to handle and the method for recover materials, the volatilizable organic pollution of industry is applicable to that catalytic combustion purifies, and the general equipment that adopts is catalytic bed.The catalytic bed primary structure comprises a body at present, air inlet, air outlet, electric heater, air distribution plate and catalytic bed, the bottom of bed body is shaped on air inlet, the top of bed body is shaped on air outlet, in the bed body electric heater is set respectively from bottom to up, air distribution plate and catalytic bed, though this kind structure can play the effect of catalytic combustion, but purifying rate is lower, catalyst is short service life, trace it to its cause for: industrial volatilizable organic pollution is to enter catalytic bed of the prior art from the below, discharge from the top, the heat energy savings all can be arranged by each catalytic bed the time, cause the catalytic bed temperature on upper strata to surpass catalyst activation temperature, catalyst is lost activity, cause purifying rate to reduce, catalyst shortening in service life; Industrial in addition volatilizable organic pollution free convection direction is operation upwards, and during through catalytic bed, waste gas begins to quicken to rise, and causes reduce the time of contact of waste gas and catalytic bed, causes purifying rate to reduce.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, design science is reasonable, and is safe and reliable, effectively increases waste gas and catalytic bed time of contact, improves the industrial volatilizable organic pollution efficient catalytic combustion purification device of purifying rate.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of industry is volatilizable organic pollution efficient catalytic combustion purification device, comprise catalytic bed body, air inlet, air outlet, electric heater, air distribution plate and catalytic bed, its catalytic bed body upper end is shaped on air inlet, catalytic bed body lower end is shaped on air outlet, is disposed with electric heater, air distribution plate and catalytic bed in the catalytic bed body from top to bottom.
And the external wall of described catalytic bed is fixed with heat-insulation layer.
And described heat-insulation layer is a pyroceram fibre.
And described air outlet is set to 3.
And described catalytic bed comprises catalyst carrier and catalyst, and catalyst carrier is a honeycomb ceramic carrier, and catalyst is alundum (Al and Bo, Palladium.
Advantage of the present invention and beneficial effect are:
1, the catalytic bed body of this industrial volatilizable organic pollution efficient catalytic combustion purification device upper end is shaped on air inlet, catalytic bed body lower end is shaped on air outlet, be disposed with electric heater, air distribution plate and catalytic bed in the catalytic bed body from top to bottom, this structure has effectively improved the time of contact of waste gas and catalytic bed, avoided upwards savings of heat energy, be temperature equalization between each catalytic bed, improved purifying rate.
2, the external wall of catalytic bed of this industrial volatilizable organic pollution efficient catalytic combustion purification device is fixed with heat-insulation layer, and heat-insulation layer is a pyroceram fibre, can effectively reduce heat energy loss, improves catalytic combustion efficient.
3, the present invention is simple in structure, design science is reasonable, and is safe and reliable, effectively increased the time of contact of organic pollution and catalyst, and improved catalytic bed bulk temperature uniformity, be a kind of industrial volatilizable organic pollution efficient catalytic combustion purification device that can improve purifying rate.

The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of industry is volatilizable organic pollution efficient catalytic combustion purification device, comprise catalytic bed body 7, air inlet 1, air outlet 6, electric heater 2, air distribution plate 3 and catalytic bed 4, the external wall of catalytic bed is fixed with heat-insulation layer 5, this heat-insulation layer is a pyroceram fibre, air outlet is set to 3, catalytic bed comprises catalyst carrier and catalyst, catalyst carrier is a honeycomb ceramic carrier, catalyst is alundum (Al and platinum Palladium, alundum (Al is one year, platinum Palladium is two years, its catalytic bed body upper end is shaped on air inlet, catalytic bed body lower end is shaped on air outlet, is disposed with electric heater in the catalytic bed body from top to bottom, air distribution plate and catalytic bed.
The present invention in use, to contain of the air inlet feeding of the waste gas of industrial volatilizable organic pollution from this device, at first heat up and reach the temperature of catalytic combustion through electric heater, evenly guide catalytic bed into by air distribution plate, because waste gas is to move from the top down, opposite with the free convection direction, so can not cause the heat energy on the catalytic bed to be put aside, the temperature of each catalytic bed is kept in balance.In addition because opposite with the free convection direction, can under the bigger situation of waste gas charge flow rate, ensure the time of contact and the distributing homogeneity of waste gas and catalytic bed, thereby improved catalytic combustion purifying rate and catalyst service life, make this device have more applicability and economy.
