For achieving the above object, the technical solution adopted in the utility model is:
A kind of graphitizing furnace exhaust gas cleaner is characterized in that: comprise the preprocessor that sequentially is connected, tubulent contact tower, moisture separator, alkaline pond and the back pool of at least two serial connections, wherein:
Sequentially be communicated with by gas piping between the tubulent contact tower of described preprocessor, at least two serial connections, moisture separator;
The tubulent contact tower of described preprocessor and described at least two serial connections respectively is connected with described alkaline pond by a upper hose;
The tubulent contact tower of described preprocessor and described at least two serial connections respectively is connected with described back pool by a downcomer.
Described graphitizing furnace exhaust gas cleaner, wherein: described moisture separator also is communicated with blast pipe.
Described graphitizing furnace exhaust gas cleaner, wherein: described back pool also is communicated with described alkaline pond by the choline pond.
Described graphitizing furnace exhaust gas cleaner, wherein: described alkaline pond also is connected with filling pipe.
Described graphitizing furnace exhaust gas cleaner, wherein: described tubulent contact tower bottom is provided with gas inlet, and top is provided with the tail gas outlet, and described tubulent contact tower inside is provided with spray head, spray head is connected with described upper hose, is provided with the lightweight Ball-type packing between described spray head and described gas inlet.
The utility model adopts at least two-stage tubulent contact tower spray-absorption step by step, and by the purification step by step of multistage purification tower, the final purification rate reaches more than 98%, reaches the tail gas clean-up discharge standard.
Description of drawings
Fig. 1 is the overall structure schematic diagram of exhaust gas cleaner;
Fig. 2 is the internal structure schematic diagram of tubulent contact tower.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of graphitizing furnace exhaust gas cleaner, comprises tubulent contact tower 2, moisture separator 3, the alkaline pond 4 and back pool 5 of the preprocessor 1 that sequentially is connected, at least two serial connections, wherein:
The tubulent contact tower 2 of described preprocessor 1 and described at least two serial connections respectively is connected with described alkaline pond 4 by a upper hose 6;
The tubulent contact tower 2 of described preprocessor 1 and described at least two serial connections respectively is connected with described back pool 5 by a downcomer 7;
In addition, sequentially be communicated with by gas piping 8 between the tubulent contact tower 2 of described preprocessor 1, at least two serial connections, moisture separator 3;
Described moisture separator 3 also is communicated with blast pipe 9;
Described back pool 5 also is communicated with described alkaline pond 4 by choline pond 10; Described alkaline pond 4 also is connected with filling pipe 11.
When using, at first graphitizing furnace tail gas w enters in described preprocessor 1, processes through spray, and tail gas is contacted with water, and the dust in water, sour gas etc. are carried away in back pool 5 by alkaline water at this moment, reduce the content of the harmful substance in gas.
Preprocessor 1 gas out enters the tubulent contact tower 2 of described at least two serial connections, and through the alkali lye spray, the harmful substance in gas also is deposited in back pool 5 by alkali liquor absorption.Gas by cyclic washing after, impurity concentration descends greatly.
Specifically, as shown in Figure 2, described tubulent contact tower 2 bottoms are provided with gas inlet 21, top is provided with tail gas outlet 22, inside is provided with spray head 23, spray head 23 is connected with described upper hose 6, be provided with lightweight Ball-type packing 24 between described spray head 23 and described gas inlet 21, described lightweight Ball-type packing 24 is under the interaction of the various power such as the buoyancy of the impulse force of rising high velocity air, liquid and self gravitation, suspend and get up to form turbulence rotation and collision mutually, cause the close contact of gas, liquid, effectively carry out mass transfer, heat transfer and dustproof function.In addition, respectively to random motion, the surface often is collided, rinses due to bead, under certain empty tower gas velocity, can produce self peace and quiet effect.And the alkaline water that is disposed in tubulent contact tower 2 is back to back pool 5 from described downcomer 7.
The harmful substances such as the dust that comprises in tail gas, acidic materials precipitate in described back pool 5, wait for post-processed (wherein powdered carbon etc. can be used as auxiliary material be utilized), the alkaline water that back pool 5 surfaces are comparatively clean enters in described alkaline pond 4 recycling after passing through described choline pond 10.
Clean gas after processing through the tubulent contact tower 2 of described at least two serial connections through after described moisture separator 3 separating treatment, is discharged in atmosphere from described blast pipe 9.
Described tail gas gas after treatment, chlorine purification efficient is more than 98%; Waste gas air quantity 6666.7m
3/ h, chlorine discharging 1.5mg/m
3, 0.01kg/h through 15 meters little qualified discharges of high exhaust, can guarantee the stably reaching standard discharging of tail gas.
This shows, the utility model adopts at least two-stage tubulent contact tower 2 spray-absorption step by step, can reach the purpose of purification.
Above explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, in the situation that do not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all falling into protection domain of the present utility model.
