Description
Technical Field
The utility model relates to a defogging device especially relates to exhaust-gas treatment's high-efficient defogging device.
Background
The high-efficiency demister is a special high-efficiency demister for waste gas treatment, is mainly used for post-stage gas phase demisting of various waste gas spray towers, prevents corrosion to a post-treatment device, a fan and a pipeline, and reduces the treatment load of the post-stage treatment device; the pre-stage gas phase demisting device is used for pre-stage gas phase demisting of various waste gas packing absorption towers, and prevents the packing from being blocked, thereby influencing the waste gas treatment effect and the like. Meanwhile, the high-efficiency demister can also be used in simple waste gas treatment application places such as oil-water separation, waste gas dust removal, liquid impurity removal and the like.
The separation method adopted by the existing demister mainly comprises gravity settling, baffling separation, centrifugal force separation, wire mesh separation, ultrafiltration separation and filler separation. The separation efficiency of two separation methods of gravity settling and baffling separation is low; the centrifugal separation method has a common separation effect, equipment generally occupies a large area, and has certain requirements on the suction force of a fan; the screen separation and filler separation effects are high, but the equipment resistance is large, so that the required air pressure is also large when the fan is selected, and the equipment investment cost is increased; the ultra-filtration separation is used for a demister for waste gas treatment, has higher cost and is generally not considered.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve current defroster separation effect not high, equipment resistance is big, the big scheduling problem of area. The utility model provides a high-efficient defroster for exhaust-gas treatment, including the defroster body, this internal gravity disengagement zone, baffling disengagement zone, centrifugal separation zone and dry-type filtering area of being equipped with in proper order from bottom to top of defroster, just gravity disengagement zone, baffling disengagement zone, centrifugal separation zone, dry-type filtering area communicate in proper order, defroster body below is equipped with the drain.
Preferably, the gravity separation area is a gravity settling area, a conical liquid storage area is arranged at the bottom of the gravity settling area and communicated with the sewage outlet, and an air inlet is further formed in one side of the gravity separation area. Waste gas enters the equipment from the air inlet, and large liquid drops carried in the waste gas flow downwards into the liquid storage area under the action of gravity due to different specific gravities of gas and liquid, so that the gas continuously flows upwards.
Furthermore, a baffle plate is vertically arranged in the baffle separation area. When the liquid in the waste gas flows through the baffle plate together with the gas, the gas can be deflected away, and the liquid impacts on the baffle plate due to inertia and then flows into the liquid storage area under the action of gravity.
Preferably, the centrifugal separation area is internally provided with fan blades and a motor for driving the fan blades, the motor is externally provided with a protective cover, and the protective cover prevents the motor from being corroded due to long-time exposure to waste gas. The fan blades are wire mesh type fan blades made of steel wires, and the fan blades and the motor form the high-efficiency interceptor. Liquid drops in the waste gas enter a centrifugal separation area, and partial liquid drops are intercepted by the centrifugal action of a high-efficiency interceptor; the residual liquid drops pass through the high-efficiency interceptor and are broken into fine fog drops by the high-efficiency interceptor.
Furthermore, the dry-type filtering area is internally and horizontally provided with filtering cotton and an air outlet, and the air outlet is arranged at the uppermost end of the demister body. The filter cotton absorbs fine fog drops in the waste gas, and the dried waste gas is discharged from the air outlet.
Has the advantages that: 1. the integrated structure has compact structure, small volume, small occupied area, convenient installation and convenient transportation.
2. The device is used for gas phase demisting in various places, and has good demisting effect.
3. The gas and the liquid are separated by four stages, the separation efficiency is high, and the water content of the discharged waste gas is extremely low.
4. The frequency of consumable (filter cotton) replacement is low during the use of the equipment, and the maintenance cost of the equipment is low.

Detailed Description
As shown in figure 2, a high-efficient defroster for exhaust-gas treatment, including the defroster body, this internal gravity disengagement zone, baffling disengagement zone, centrifugal separation zone and the dry-type filtering zone of being equipped with in proper order from bottom to top of defroster, just gravity disengagement zone, baffling disengagement zone, centrifugal separation zone, dry-type filtering zone communicate in proper order, defroster body below is equipped with drain 1.
The gravity separation area is a gravity settling area, a conical liquid storage area 9 is arranged at the bottom of the gravity settling area, the liquid storage area 9 is communicated with the sewage outlet 1, and an air inlet 2 is arranged on one side of the gravity separation area. And a baffle plate 3 is vertically arranged in the baffling separation area. The centrifugal separation area is internally provided with fan blades 4 and a motor 5 used for driving the fan blades 4, and the outside of the motor 5 is provided with a protective cover 6. The dry-type filtering area is internally and horizontally provided with filter cotton 7 and an air outlet 8, and the air outlet 8 is arranged at the uppermost end of the demister body.
The specific working principle is as follows: waste gas enters from an air inlet 2 at the lower part of the high-efficiency demister, and airflow in the equipment shell flows from bottom to top. The waste gas firstly enters the gravity separation area, because of the different specific gravity of the gas and the liquid, the bigger liquid drops carried in the waste gas can flow downwards into the liquid storage area 9 under the action of gravity, and the rest waste gas upwards enters the baffling separation area. When the liquid in the exhaust gas flows through the baffle plate 3 together with the gas, the gas is deflected away, and the liquid impacts on the baffle plate 3 due to inertia and then flows into the liquid storage area 9 under the action of gravity. The waste gas after gravity separation and baffle plate 3 separation, wherein the carried liquid is mainly smaller liquid drops, the waste gas enters the centrifugal separation area upwards, part of the liquid drops are intercepted by the centrifugal action of the fan blades 4, and the rest liquid drops pass through the fan blades 4 and are scattered into fine fog drops by the fan blades 4. The fine fog drops are carried by the waste gas and are absorbed by the filter cotton 7 when flowing through the dry-type filtering area, and the dry waste gas is discharged through the air outlet 8.
