Description

Water mist adsorption filtration type chimney dust removal purifier

Technical Field

The utility model belongs to boiler equipment mainly relates to a dress and adopts water smoke adsorption filtration dust removal's clarifier of dress on the chimney of boiler emission flue gas.

Background

In order to reduce and eliminate particulate matters carried in boiler flue gas emission and reduce pollution to the atmospheric environment, dry type sand-k dust collectors are arranged in existing coal-fired fuel boiler equipment, and the dry type sand-k dust collectors recycle particulate matters with large specific gravity contained in the flue gas through centrifugal force generated by rotation of the flue gas in the emission process. In the practice of production and use for many years, the dry-type sand-cock dust collector is found to be only capable of recovering and treating larger particles contained in the flue gas, and cannot remove fine particles and particles with lighter specific gravity, so that the dry-type sand-cock dust collector cannot adapt to and meet the requirement of higher standard on flue gas emission. Particularly, in recent years, with the development and application of crop straw fuel boilers, the contents of fine particles and particles with lighter specific gravity in the discharged flue gas are greatly increased, and the dry type sand-dragon dust remover cannot bear and complete the dust removal operation requirements.

Disclosure of Invention

The utility model discloses a purpose is exactly to the problem that above-mentioned prior art exists, combines the actual demand that current boiler flue gas emission dust removal operation used, develops a water smoke adsorption filtration formula chimney dust removal purification ware, reaches the purpose that increases substantially boiler emission flue gas dust removal quality and effect, application capability are strong, application scope is wide.

The basic design of the utility model is that: the water atomization filtering type chimney dust removal purifier is characterized in that an annular water jacket and an annular net rack are sequentially and horizontally fixedly arranged in a cylindrical shell from top to bottom, a water atomization nozzle is arranged on the bottom side part of the annular water jacket, a water inlet pipe is fixedly arranged on the cylindrical shell wall, the water inlet pipe is communicated with the annular water jacket, a conical flow distribution plate is arranged at the upper end of the center of the annular net rack, an adsorption material layer is laid on the annular net rack, a sewage separation barrel is fixedly arranged in the bottom end of the cylindrical shell, a sewage discharge pipe is assembled at the bottom of the cylindrical shell wall, and the sewage discharge pipe is positioned on the outer side of the cylindrical wall of the sewage separation barrel, so that the water atomization filtering type chimney dust removal purifier is formed.

The utility model discloses an adsorbing material adsorbs and sprays wet-type combination dust removal structure with the water smoke and can reliably effectually clear away the particulate matter that contains in the boiler fuel burning emission flue gas, avoids the pollution to atmospheric environment, especially can satisfy the supporting use of boiler that uses crop straw as fuel, has simple structure, reasonable, novel, dust removal effect good, efficient, use reliable, low in manufacturing cost is honest and clean, application scope is wide, the commonality is strong, be favorable to environmental protection's characteristics.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The utility model provides a water smoke adsorption filtration formula chimney dust removal purification ware, is at 1 inside from last to adorning annular water jacket 2 and annular net rack 4 admittedly down in proper order the level from top to bottom install water atomization nozzle 3 on the bottom lateral part of annular water jacket 2 adorn inlet tube 9 admittedly on 1 section of thick bamboo wall of cylindric casing, inlet tube 9 and annular water jacket 2 intercommunication install conical flow distribution plate 8 on the annular net rack 4 center upper end position lay adsorption material layer 7 on the annular net rack 4 1 bottom is inside adorns admittedly sewage and separates a fender section of thick bamboo 5, and sewage discharge pipe 6 is furnished with on 1 section of thick bamboo wall bottom of cylindric casing, sewage discharge pipe 6 is located sewage and separates the section of thick bamboo wall outside that keeps off a section of thick bamboo 5.

When in use, the purifier is arranged on a smoke discharge port of boiler equipment, and a chimney is arranged on the upper end part of the purifier. Flue gas discharged after boiler fuel combustion enters the cylindrical cavity of the cylindrical shell 1 from the discharge port through the sewage blocking cylinder 5 from bottom to top, and then enters the chimney through the annular net rack 4, the adsorption material layer 7 and the annular water jacket 2 in sequence to be discharged. After the flue gas gets into cylindric casing 1, pressure water fills into annular water jacket 2 in from inlet tube 9 in, spouts into cylindric casing 1 after the atomizing of water atomizing nozzle 3 in, and the particulate matter sprays the whereabouts in the exhaust flue gas that will rise to erode the outside that falls to cylindric casing 1 downside sewage separation and keep off a section of thick bamboo 5 in the lump with attached particulate matter when passing through adsorption material layer 7 with the flue gas simultaneously, discharges through sewage discharge pipe 6, accomplishes the dust removal purification operation. The conical splitter plate 8 can guide the sprayed and splashed atomized water to the annular net rack 4 and the adsorption material layer 7, so that the operation quality and effect are improved.
