Description
Technical field
The utility model relates to technical field of environment protection equipment, and in particular to a kind of wet scrubber.
Background technique
Wet scrubber is a kind of common cleaner, it is to connect dusty gas closely with liquid (generally water)
Touching, using water droplet and particle inertial collision or using water and dust be sufficiently mixed effect and other effect arrested particles or
Increase particle, stays dust in the device for reaching flue gas and dust separation effect in fixed container.
108636021 U of Chinese patent CN discloses a kind of wet scrubber, does not spray only with spray head, adopts simultaneously
Steam is generated with air-flow self-excitation, increases efficiency of dust collection；Chinese patent CN 207838586 U, CN 108635968 A etc. use
Roughly the same mode dedusting.
But these wet scrubbers have certain limitation when being applied to flue gas of refuse burning dedusting, because in flue gas
Containing certain sour gas, sour gas can be dissolved in the water that the pH of dissolution water is caused to reduce when flue gas passes through water, into
And equipment is easily corroded, while the dust of these wet scrubber sub-departments is not easily settled.
Utility model content
In view of the above technical problem, the purpose of this utility model is to provide a kind of wet scrubbers, by the way that lye is arranged
Tank adjusts the pH of water, and then absorbs sour gas remaining in flue gas, by setting flocculation tank and inclined plate, so that the sedimentation of dust
Effect is more preferable.
The utility model uses following technical scheme are as follows:
A kind of wet scrubber, including water storage box, gas-water separation case and spraying and dedusting pipe, the gas-water separation case, which is set to, to be stored
Above water tank, the spraying and dedusting pipe is connected to the gentle water separating tank of water storage box, is equipped with rotary nozzle, the storage in spraying and dedusting pipe
Be equipped with partition in water tank, water storage box is divided into dedusting chamber and cushion chamber by the partition, the inside of the dedusting chamber be equipped with flue gas into
Mouthful pipe and inclined plate, bottom be equipped with sludge collection bucket, top be equipped with pH on-line computing model and filler, the flue gas inlet tube go out
Horizontal plane where mouthful guarantees flue gas inlet tube when dedusting is intracavitary adds water to isolation board lower than place horizontal plane at the top of partition
Outlet is located at below the water surface, intracavitary, the buffering that the probe of the pH on-line computing model across dedusting chamber top side is placed in dedusting
Intracavitary to be equipped with immersible pump, the immersible pump is connected to spray head；
The top of the gas-water separation case is equipped with smoke outlet tube, the internal diversion pipe that is equipped with is equipped with and is connected to silk screen, bottom
The drainpipe of dedusting chamber, horizontal plane where the outlet of the drainpipe add lower than place horizontal plane at the top of partition when dedusting is intracavitary
When water to isolation board, guarantee that the outlet of flue gas drainpipe is located at below the water surface, the diversion pipe is set in steam-water separation case inside
At heart line, the wire diameter sizes are equal to steam-water separation case internal diameter, and center passes through diversion pipe；
Alkali liquid tank and flocculant tank are additionally provided on the outside of the water storage box, the alkali liquid tank and flocculant tank are connected by pipeline
Logical dedusting chamber, flocculant accelerate the sinking speed of dust in flue gas, and alkali liquid tank adjusts pH.
Further, the inclined plate is set between partition and flue gas inlet tube, and inclined plate sedimentation is utilized in the inclined plate of setting
Principle accelerates the sinking speed of dust in water, and the probe of the pH on-line computing model is set between partition and flue gas inlet tube,
The water that the partition of setting makes dedusting intracavitary is only capable of flowing to cushion chamber by way of spilling, so that the precipitating of dedusting chamber middle and lower part
Particle is unlikely to as water flow is to cushion chamber.
Compared with prior art, the utility model has the beneficial effects that:
1. the utility model absorbs the remaining acid gas in flue gas by setting pH on-line computing model and alkali liquid tank,
Corrosion of the sour gas to equipment is avoided, and the wet scrubber of same type, due to not set alkali liquid tank, sour gas is in water
It is more serious to the corrosion of equipment under the action of steam.
2. by setting flocculation tank and inclined plate, so that the effect of settling of dust is more preferable, by the way that sludge bucket is arranged, so that sedimentation
Dust in water is more easier to collect, by the way that partition is arranged, so that only settling after dust is that can be entered by immersible pump
Spray head avoids immersible pump and spray head because of sludge blockage；
3., so that gas-water separation effect is more obvious, avoiding flue gas discharge Shi Yinhan by setting silk screen and diversion pipe
There are a large amount of vapor into white smoke, form visual pollution.
Detailed description of the invention
Fig. 1 is the utility model overall schematic；
In figure, 1 gas-water separation case, 2 water storage boxes, 3 flue gas inlet tubes, 4 spraying and dedusting pipes, 5 smoke outlet tubes, 6pH is online
Monitor, 7 alkali liquid tanks, 8 flocculant tanks, 9 inclined plates, 10 immersible pumps, 11 spray heads, 12 silk screens, 13 diversion pipes, 14 filler, 15 every
Plate, 21 cushion chambers, 22 dedusting chambers.
