Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1

As shown in fig. 1, a high-efficiency hybrid wet dust collector comprises a frame 1, wherein a platform 2 is arranged above the frame 1, an air inlet pipe 3 is arranged on one side of the platform 2, a spray humidifier 4 is arranged below the air inlet pipe 3, a high-speed impact channel 6 is arranged below the spray humidifier 4, an air outlet pipe 10 is arranged on the other side of the spray humidifier, a double-layer backwashing structure 7 is arranged below the air outlet pipe 10, a dehydration layer 9 is arranged inside the double-layer backwashing structure 7, a multi-stage dehydration structure 8 is arranged below the double-layer backwashing structure 7, and a dust hopper 11 is arranged below the multi-stage dehydration structure 8.

The ash bucket 11 is communicated with the multi-stage dewatering structure 8 through a drain pipe 12.

The high-speed impact channel 6 is communicated with a drain pipe 12 through a flow equalizing pipe 5.

The working process comprises the following steps: the flue gas before purification enters the purification system through the air inlet channel 3, and the air inlet channel 3 not only plays the role of a transition channel, but also plays the role of equalizing the wind to different bins; then get into and spray humidifier 4, it adopts big wet process to spray, and water adsorbs the dust, and dust humidity increases, and the granularity increases, increases viscidity each other and the probability of collision, and the purpose is two: 1. part of the dust directly falls into the ash bucket along with the water particles to achieve the aim of dust removal; 2. the part which is not dedusted is beneficial to the absorption and dedusting of the flow equalizing pipe 5 and the high-speed impact channel 6 after the granularity and the humidity are increased; pass through flow equalizing pipe 5 again, adopt multichannel modularized design, adopt the PP material, every module contains a plurality of flow equalizing pipe 5, and flow equalizing pipe 5 is the design of thin choke in the middle of the both ends is thick, plays the impact, and it gives vent to anger to flow equalize adopts the lower part to part porous giving vent to anger, and the structure of not giving vent to anger of low side, and the design of flow equalizing pipe 5 plays three purpose: 1. the multi-channel design plays a role in even distribution; 2. the throat pipe is designed, so that the liquid level can be better washed, and the humidification can be further realized; 3. the design of multiple air outlets plays roles in full collision, combination and dust removal of air flow; the air flow washes the liquid surface in the high-speed impact channel 6 at the speed of 30-50m/s, so that the liquid surface stimulates a layer of water mist, dust and water are fully mixed, enlarged and wetted, and then enters the multi-stage dehydration structure 8; after entering the multi-stage dehydration structure 8, the flow velocity is rapidly reduced, and common large-particle dust can be settled; the multistage dewatering structure 8 adopts the structural design of the multistage curved arc baffle plate, so that the airflow moves spirally, collision dust removal is not only realized, but also centrifugal dust removal is realized, the superposition effect of multiple dust removal is realized, and the dust removal effect is more ideal; then the dust accumulated in the dehydration layer 9 in the middle of the double-layer back flushing structure 7 is cleaned by adopting an upper back flushing layer and a lower back flushing layer, so that the ventilation of the dehydration layer 9 is ensured; the dewatering layer 9 adopts a brand-new designed superfine stainless steel wire mesh modular structure, the height, the wire diameter and the density of the wire mesh reach the most economic design parameters through experiments, so that the air permeability is ensured, and the dewatering and dust removing effects are also ensured; the purified flue gas enters the fan through the gas outlet channel 10 and is discharged through the exhaust funnel.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
