Description
(1) technical field
The present invention relates to a kind of industrial waste gas absorbing recovery device.
(2) background technology
People adopt absorbing recovery device to adsorb various places exhaust gas discharged usually at present, and this absorbing recovery device generally includes gas collector, some adsorption tanks, condenser and liquid separator; Each adsorption tank bottom is provided with the gas access, the bottom is provided with liquid outlet, the top is respectively equipped with steam inlet and exhaust port, described gas access, liquid outlet, steam inlet and exhaust port are respectively equipped with valve, described gas collector is communicated with the gas access, liquid outlet is communicated with condenser, and condenser is communicated with liquid separator; The waste gas adsorbent equipment is installed in the described adsorption tank.Each absorber has three kinds of states to circulate mutually, promptly absorption, intermittently, desorption, intermittently, absorption, always the circulation go down, a plurality of adsorption tanks are carried out this three states mutually by turns.The relevant patent such as the CN2538410Y of this type of technology, CN2604223Y, CN2796806Y etc.The shortcoming of this class absorbing recovery device is: because the waste gas adsorbent equipment adopts at absorbent core outer wrapping NACF, and when the water vapour desorption, moisture is stayed in the NACF, reduced adsorption efficiency, obviously increased equipment cost and operating cost and in this device, install drying equipment again additional; Simultaneously, because the NACF gas-flow resistance is big, high-temperature steam is skewness in adsorption tank, for preventing that the cell body inwall from getting rusty, the expensive stainless steel material of the many employings of adsorption tank, gas-flow resistance is big in addition also makes the power of fan with this matched with devices strengthen, thereby production cost and operating cost are higher.
(3) summary of the invention
Technical problem to be solved by this invention is a kind of adsorption efficiency height, manufacturing cost and the low industrial waste gas absorbing recovery device of operating cost.
Industrial waste gas absorbing recovery device of the present invention comprises gas collector, some adsorption tanks, condenser and liquid separator; Each adsorption tank bottom is provided with the gas access, the bottom is provided with liquid outlet, the top is respectively equipped with steam inlet and exhaust port, described gas access, liquid outlet, steam inlet and exhaust port are respectively equipped with valve, described gas collector is communicated with the gas access, liquid outlet is communicated with condenser, and condenser is communicated with liquid separator; The waste gas adsorbent equipment is installed in the described adsorption tank; described waste gas adsorbent equipment is the charcoal bed of lateral arrangement in adsorption tank inside; tiling has the seed activity carbon adsorbent on the described charcoal bed, and described charcoal bed is provided with perforate, and the diameter of perforate is less than the diameter of adsorbent.
Further, also be provided with pneumatic filter between described gas collector and the gas access.
Further, each valve connects pneumatic actuating unit respectively, and each pneumatic actuating unit connects same control system.
Further, described adsorption tank adopts carbon steel material.
Beneficial effect of the present invention is:
1, adopt activated carbon granule as adsorbent, its desorption and regeneration energy consumption is low, and gas-flow resistance is little, and required power of fan is little, has realized low-cost big air quantity processing;
2, behind the employing carbon bed, high-temperature steam being evenly distributed in adsorption tank, adsorption tank adopts carbon steel material also to be difficult for getting rusty, thus production cost reduces greatly;
3, activated carbon granule is difficult for absorption moisture content, thereby can keep high adsorption efficiency always;
4, adopt control system that automatic control has been carried out in the operation of this device, realized unattended operation, good reliability, simple to operate, be convenient to safeguard.
(4) description of drawings
Fig. 1 is the structural representation of the described industrial waste gas absorbing recovery device of embodiment.
(5) specific embodiment
The invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this.
With reference to Fig. 1, a kind of industrial waste gas absorbing recovery device comprises gas collector 1, six adsorption tanks 2, condenser 3 and liquid separators 4; Each adsorption tank bottom is provided with gas access 5, the bottom is provided with liquid outlet 6, the top is respectively equipped with steam inlet 7 and exhaust port 8, described gas access 5, liquid outlet 6, steam inlet 7 and exhaust port 8 are respectively equipped with valve, described gas collector 1 is communicated with gas access 5, liquid outlet 6 is communicated with condenser 3, and condenser 3 is communicated with liquid separator 4; In the described adsorption tank 2 the waste gas adsorbent equipment is installed; described waste gas adsorbent equipment is the charcoal bed 9 of lateral arrangement in adsorption tank 2 inside; tiling has the seed activity carbon adsorbent on the described charcoal bed 9, and described charcoal bed 9 is provided with perforate, and the diameter of perforate is less than the diameter of adsorbent.
Also be provided with pneumatic filter 10 between described gas collector 1 and the gas access 5.
Each valve connects pneumatic actuating unit respectively, and each pneumatic actuating unit connects same control system.
Described adsorption tank 2 adopts carbon steel material.
The technological process of production of the present invention is: industrial waste gas enters gas collector 1, and deliver to pneumatic filter 10 earlier by blower fan, enter adsorption tank 2 by gas access 5 again, waste gas is risen by the perforate that adsorption tank 2 bottoms are passed on the charcoal bed 9, organic substance in the uphill process in the waste gas is by the absorption of the activated carbon granule on the charcoal bed 9, and the gas that the absorption back is clean is discharged by exhaust port 8; Steam inlet 7 and liquid outlet 6 are closed in the adsorption process.When the active carbon in the adsorption tank absorbs near when saturated, close gas access 5 and exhaust port 8, open steam inlet 7 and liquid outlet 6, high-temperature steam 7 is entered in the adsorption tank through the steam inlet by steam generating equipment 11, the organic substance that is adsorbed in the adsorption tank is resolved through steam and is left activated carbon surface, mix by liquid outlet 6 with water vapour and to enter condenser 3, liquid enters liquid separator 4 and carries out sedimentation separation after the condensation, separates the back organic matter and enters storage tank 12.Six adsorption tanks of the present invention under control system control, periodically alternately absorption, intermittently, desorption, absorption, desorption time can be set according to workshop exhaust gas concentration, air quantity.
