Background technique
Since the new period, people start to using sacrificialing environment and life and health as the extensive development model of cost
Self-examination becomes the maximum killer that people pursue healthy living because of the secondary injury of its persistence and potentiality；This year, country are right
The management of volatile organic compounds is increasing, especially attention is strengthened to uncontrollable discharge gas, in production process
The uncontrollable discharge exhaust gas of middle generation is usually present feature large-minded, that concentration is low, directlys adopt simple treatment process
It there is a problem that poor processing effect or investment operating cost are high.
Currently, in the improvement of the organic exhaust gas of low concentration, Adsorption Concentration-Production by Catalytic Combustion Process is widely used, but should
Method there are occupation area of equipment it is big, operating process is more complex the problems such as, in addition using the processing unit of this method greatly mostly use plus
Nitrogen after heat is as desorption gas, this just needs the public works coordinative composition of equipments such as steam, nitrogen, and the construction period is longer, only fits
It is limited, public mating incomplete to those urgent need waste gas pollution control and treatments, place for of certain scale, mating more perfect enterprise
Enterprise has some limitations.
Summary of the invention
Use and install that more convenient, operating cost is lower the technical problem to be solved by the utility model is to provide a kind of
And the processing unit of energy-saving and environment-friendly low-concentration organic exhaust gas.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of processing of low-concentration organic exhaust gas
Device, including filter, the adsorption/desorption bed for being provided with active carbon, the first blower, the first fire arrester, the second blower, catalytic bed,
Second fire arrester and third blower, the entrance of the filter is for receiving external low-concentration organic exhaust gas, the filtering
The outlet of device passes through the absorption inlet communication of the first valve and the adsorption/desorption bed, and the adsorption/desorption bed absorbs
Mouth is connected to by the second valve with the air inlet of first blower, and the gas outlet of first blower is used for external high
The desorption of empty discharge gas, the adsorption/desorption bed is connected by the import of third valve and first fire arrester
Logical, the outlet of first fire arrester and the inlet communication of second blower, second blower, which is provided with, to be used for
Suck the air scoop of outside air, the outlet of second blower and the inlet communication of the catalytic bed, the catalysis
The outlet of bed is connected by the first pipeline with the import of second fire arrester, and the outlet of the catalytic bed passes through the second pipe
Road is connected to external high-altitude, the import of the third blower for sucking outside air, the outlet of the third blower with
The outlet of the inlet communication of second fire arrester, second fire arrester passes through the 4th valve and the adsorption/desorption
The desorption inlet communication of bed.
It further include all-in-one machine shell, it is the filter, the adsorption/desorption bed, first blower, described
First fire arrester, second blower, the catalytic bed, second fire arrester and the third blower are respectively provided with
In the all-in-one machine shell.Overall structure is simple, small volume, can be used as integrated apparatus and is designed and produces, makes
With and place it is more convenient.
Compared with prior art, the utility model has the advantage of realize adsorption process by adsorption/desorption bed and be desorbed
Journey, number of devices is less, uses and installs and is more convenient；Realize that the inner air of system in desorption process follows by the second blower
Circulation is dynamic, and use when institute's calorific requirement is directly provided by interior arrangement, provides heat source without individual external heating equipment, effectively returns
Reaction heat is received, energy reuse is realized, substantially reduces operating cost；When handling low-concentration organic exhaust gas, it can be achieved that tail gas is up to standard
Discharge, can effectively solve the low concentration gas emission problem of the industries such as spray painting, shoemaking, light industry, be the energy only with electric energy, mating
Simply, it can effectively avoid that place is limited, the mating infull problem of synergic system, the scope of application is wider；It is generated in use process
The three wastes are less, safety and environmental protection, and adsorption and desorption technique realizes the long-term operation of active carbon, and it is direct to avoid conventional carbon
Absorption generates the shortcomings that a large amount of solid wastes, substantially without secondary pollution.
