Abstract

The utility model discloses a desulphurizing dust remover. A flue gas partition board is arranged on the upper part of an ash collection pond and the connection of an ash-laden gas leading cylinder and a cleaning flue gas leading cylinder, and the middle part of the flue gas partition board is provided with the connection hole of the through holes of the cleaning flue gas leading cylinder, a smokes separation pipe whose bottom is sunk under the liquid level of the ash collection pond is hoisted on the environment of the partition board, and in the cleaning flue gas leading cylinder, a shower pipe is arranged. Lime water is used as shower water, which can eliminate 80-90% of sulfur dioxide in the flue gas. The dust removing efficiency can reach 95%.

Description

Desulphurizing dust remover for use in brick-field

The utility model provides a kind of brick field sulphur removal deduster, and it includes ash-laden gas and imports tube, collection ashpit, divides fume pipe, purifies assemblies such as flue gas export cylinder, overflow pipe.Belong to the dust separation device in the operation.

Acid rain is a kind of to structures and the very big industrial pollutants of farm-forestry crop threat.During China's acid rain forms, very big some is arranged from the brickkiln flue gas that spreads all over town and country.An at village level little brick field, its smoke discharge amount are often greater than one 20 tons boiler, and visible acid rain harm had both spreaded all over town and country in China, and was very serious again.And existing industrial dedusting device uses but be unsuitable for this specific production environment of brickkiln.How to remove the brickkiln sulfur in smoke, the pollution of eliminating acid rain has become problem anxious to be solved.

The purpose of this utility model promptly is at the deficiency of eliminating brickkiln flue gas harm technology, and a kind of sulphur removal deduster that the town and country brickkiln purifies flue gas that is specially adapted to is provided.

Above-mentioned purpose of the present utility model realizes by taking following technical measures.

Importing tube by ash-laden gas, importing a purification flue gas export cylinder that tube joins, be arranged at ash-laden gas and import tube and purify in the deduster that collection ashpit, overflow pipe, the smoke separating pipe of flue gas export cylinder joint form with ash-laden gas, top at the collection ashpit, ash-laden gas imports tube and purifies the joint of flue gas export cylinder, the middle part is set has the flue gas dividing plate that purifies flue gas export cylinder connecting hole, the bottom is sunk to the subsurface smoke separating pipe of collection ashpit and is lifted on around the dividing plate; Purify in the flue gas export cylinder shower is set.

When making shower water with limewash, because the smoke separating pipe that ash-laden gas at first lifts on dividing plate enters the collection ashpit, contained sulfur dioxide is collected limewash absorption in the ashpit in the flue gas, forms calcium precipitation in the pond.Float the flue gas bubble after collection ashpit liquid level breaks, be agglomerated into flue gas stream again and rise, and be subjected to the washing of the spray limewash of shower, make flue gas obtain final dusting, sulphur removal purification.

Use sulphur removal deduster provided by the utility model, with limewash as shower water, 80～90% sulfur dioxide in can removing smoke, efficiency of dust collection can reach 95%.Can effectively purify the brickkiln flue dust, avoid the generation of acid rain fully.The sulphur removal deduster can be according to the production reality of brickkiln, is designed to vertically, directly is placed on the exhaust opening of brickkiln air-introduced machine, and is easy to use.

Accompanying drawing is the organigram of sulphur removal deduster.By most preferred embodiment, further narrate technical characterictic of the present utility model below in conjunction with accompanying drawing.

The sulphur removal divider imports tube (3) by the back taper ash-laden gas, import the purification flue gas export cylinder (7) that tube joins with ash-laden gas, being arranged at ash-laden gas imports tube and purifies the funnel type collection ashpit (4) that the flue gas export cylinder is joined, overflow pipe (2), smoke separating pipe (6), and on collection ashpit (4) top, ash-laden gas imports tube (3) and purifies flue gas export cylinder (7) joint, the middle part that is provided with has the flue gas dividing plate (9) that purifies flue gas export cylinder connecting hole, the bottom sink to smoke separating pipe (6) in the collection ashpit liquid be lifted on dividing plate (9) around, be arranged on the shower (8) that purifies in the flue gas export cylinder and constitute.

In the present embodiment, collection ashpit liquid level 100mm is sunk in the smoke separating pipe bottom, and the long 150mm of smoke separating pipe (6) uses 1 writing brush to make, and tube wall is 20mm at interval, and collection ashpit baffle plate (5) exceeds dividing plate (9) 30mm.Shower (8) top is a funnel-form, and hopper walls and spray tube wall are drilled with spray apertures, and collection ashpit (4) bottom has slag-drip opening (1).

Claims
