Abstract
The invention relates to a water drop grid device, and in particular relates to a water drop grid device for removing dust in flue gas. The water drop grid device comprises a plurality of atomizing nozzles which are combined together and face towards the same direction, wherein, water supply ends of the atomizing nozzles are connected with a water supply device via pipes. The water drop grid device has the advantages that a non-settled combination of dust and water mist is subjected to secondary treatment after primary flue gas treatment, namely, the combination which is not settled at the first time is captured by virtue of the formed denser water mist and then is settled and discharged, which further effectively lowers ash content in the flue gas and meanwhile better overcomes defects of the original metal wire grating such as easiness in blockage, difficulty in washing and the like.
Description
Technical field
The present invention relates to a kind of water droplet grid device, belong to environmental technology field flue gas ash removal.
Background technology
Along with the fast development of industry, country has attached great importance to environmental protection, and one of efforts at environmental protection are exactly depositing dust, the dust suppression of flue gas, the waste gas of emission abatement.To reach national waste gas emission standard.
Water smoke is a kind of cost-effective method of using always to the purification of discharging waste gas.Purifying flue gas with water smoke at present is to adopt big flow nozzle for atomizing water with air, produces average fogdrop diameter and be about 250um that (weight ratio of its droplet size generally is divided into: fogdrop diameter is: following about 6 one-tenth of 150um; What 150um was above accounts for about 4 one-tenths), fully combine with flue gas (when being 8m/s according to the flow velocity of general flue gas, fogdrop diameter is: below the 150um be can not fall heavy; Fogdrop diameter is: 150um is above heavy for falling), combination sedimentation that can sedimentation is discharged, and less combination will be discharged chimney with air-flow, so efficiency of dust collection is low, and the dust burdening of combustion gas is generally 100mg/Nm
3About.In order to reduce the dust burdening of combustion gas, people adopt the fine and close tangible grid of wire (also claiming moisture separator) to catch the efficient (dust burdening of waste gas can reach about 30mg/Nm) that less combination improves dedusting, but the wire grid easily stops up and is difficult to clean, therefore it is undesired to work, and can not apply.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of replacement existing wire grid, in order to further effectively to reduce the water droplet grid device of the dust burdening of discharging flue gas.
Technical scheme of the present invention is: the present invention includes some atomizers of combining, each atomizer is towards unanimity, and the water supply end of each atomizer is connected with water supply installation by pipeline.
Each atomizer is on the same horizontal plane, and along circumferentially evenly being provided with.
Advantage of the present invention is: water droplet grid device of the present invention is after flue gas carries out single treatment, to after the single treatment not the combination by dust and water smoke of sedimentation carry out after-treatment, water droplet grid device utilization of the present invention forms bigger water smoke and catches for the first time the not combination of sedimentation, sedimentation is discharged then, the dust burdening of flue gas is further effectively reduced, also overcome defectives such as original wire grid easily stops up, difficult cleaning simultaneously preferably.
Description of drawings

The specific embodiment
The present invention carries out after-treatment to flue gas, is arranged on the flow area of flue gas; The present invention can make corresponding shape according to the shape of different chimney walls 2, so that it is fixed on the chimney wall 2, it is interior so that flue gas flows through from atomizer 1 that atomizer 1 extends to flue, and atomizer 1 connects water rings 4 by water pipe 3.The contrary flue gas flow direction setting of the injection direction of atomizer 1 of the present invention, for better, more uniform formation mist field, each atomizer 1 of the present invention is arranged on same horizontal plane, and along circumferentially evenly being provided with, the mist field of atomizer formation will be evenly and firmly like this, can effectively catch the flue gas of all directions, to reduce the dust burdening of flue gas to greatest extent, simultaneously in order to form the mist field of different fogdrop diameters, to adapt to different needs, the number that the present invention is provided with by atomizer 1, the difference and the other factors of hydraulic pressure are regulated, to form the mist field of different fogdrop diameters.
The course of work of the present invention is, forms the mist field by atomizer 1, and flue gas is during by the mist field, and the combination of sedimentation and water smoke are not had an effect, and are caught by water smoke, and sedimentation is discharged then.
Claims (2)
1. water droplet grid device is characterized in that, comprises some atomizers of combining, and each atomizer is towards unanimity, and the water supply end of each atomizer is connected with water supply installation by pipeline.
2. water droplet grid device according to claim 1 is characterized in that each atomizer is on the same horizontal plane, and along circumferentially evenly being provided with.
