Abstract

The utility model relates to a duster, particularly a desulfurizing dust collector. A plurality of inner plane baffles and inner arc-shaped flow guiding plates form smoke passages. Smoke impacts the passages many times, causing that dust and water content in the smoke form particles; the particles can gradually enlarge and fall back to a deslagging bucket for discharging into a sedimentation tank under the action of gravity. The utility model has the advantages of reasonable structure, stable and convenient operation and high efficiency. The utility model can be widely used for desulfurizing and collecting dust for heating industrial boilers, etc.

Description

A kind of desulfurizing dust-collector

The utility model relates to a kind of deduster, especially a kind of desulfurizing dust-collector.

Existing desulfurizing dust-collector has sparge pipe, takes up room and wastes the water source, and the inner chamber dividing plate is single, and the flue gas collision frequency is few, and dust cohesion is complete inadequately, the desulfurization and dedusting weak effect; There is a rotatable arc adjustable plate deduster inside that also has, is used for regulating artificially the operating angle of deflector, has increased operation easier like this, and is wayward, thereby cause the desulfurized effect instability; Moreover the ash discharge structure of existing desulfurizing dust-collector all is to adopt lower cone directly to let out formula ash discharge valve, will emit a large amount of water in the time of outside discharging dust, caused the complicated of a large amount of wastes of water and operation.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of do not have sparge pipe, deflector fixed angle, water saving, efficiency of dust collection height, easy to operate desulfurizing dust-collector are provided.

For achieving the above object, the measure that the utility model is taked is: a kind of desulfurizing dust-collector, mainly be fixed in the water tank and the other end is positioned at the overflow pipe of sedimentation basin top and be fixed in casing, the deslagging bucket that is used to constitute some plane clapboards and arc deflectors of exhaust gases passes and be positioned at the casing lower end forms by casing, sedimentation basin, the water tank that is fixed on casing lower end one side, an end, it is characterized in that arc deflector with certain fixed angle, arc deflector be positioned at another arc deflector and a plane clapboard bottom a side; The deslagging bucket is made of taper dust chamber, heavy ash bucket, interior top formula ash-valve, ash discharge lever; Overflow pipe stretches on the interior pipeline of water tank and offers at least three water level adjustment holes.

Compared with the prior art the utility model has characteristics rational in infrastructure, that floor space is little, easy and simple to handle; The loss of water when interior top formula ash-valve can be controlled ash discharge, but using water wisely; Adopt unique inner liner prescription and paint-on technique simultaneously, make it to have high temperature resistant, wear-resisting, corrosion resistant performance, prolonged service life greatly.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a work connection layout of the present utility model.

As shown in Figure 1, desulfurizing dust-collector described in the utility model is mainly by casing 5, sedimentation basin 14, be fixed on the water tank 9 of casing 5 lower ends one side, one end is fixed in the water tank 9 and the other end is positioned at the overflow pipe 10 of sedimentation basin 14 tops and is fixed in casing 5, be used to constitute the plane clapboard 2 of exhaust gases passes, 4,6,18,19,20,21,22 and

arc deflector

7,8 and the deslagging bucket that is positioned at casing 5 lower ends form, arc deflector 8 bend towards box body wall and with certain fixed angle on the internal chamber wall of casing 5, arc deflector 8 is positioned at a side of arc deflector 7 and plane clapboard 20 bottoms, plane clapboard 2 forms an angle with vertical direction, the one end is fixed on the cabinet wall of gas approach 3 tops, the other end stretches to the center of casing 5 and fixedlys connected with the upper end of vertical plane clapboard 4, the upper end of the lower end of plane clapboard 4 and plane clapboard 6 and plane clapboard 20 fixes,

plane clapboard

6,20 form an angle with vertical direction, fixedly connected with the upper end of arc deflector 7 in the lower end of plane clapboard 6, arc deflector 7 bends towards casing 5 center positions, the lower end of plane clapboard 18 is fixed on the internal chamber wall of casing 5, its upper end fixes with the lower end of plane clapboard 19, the upper end of plane clapboard 19 also is fixed on the internal chamber wall of casing 5, the lower end of plane clapboard 21 is fixed on the internal chamber wall of casing 5, its upper end fixes with the lower end of plane clapboard 22, the upper end of plane clapboard 22 also is fixed on the internal chamber wall of casing 5,

plane clapboard

18,19,21,22 all have a certain degree with vertical direction; The deslagging bucket is made of taper dust chamber 11, heavy ash bucket 16,17, interior top formula ash-valve 15, ash discharge lever 12,13, and ash-valve 15 is positioned at the top of sedimentation basin 14; Overflow pipe 10 stretches on the pipeline in the water tank 9 and offers at least three water level adjustment holes; The upper end of casing 5 has exhanst gas outlet 1.

The connection layout in desulfurizing dust-collector when work as shown in Figure 2, the exhanst gas outlet 1 of desulfurizing dust-collector links to each other with air-introduced machine 23 by pipeline 24.

The hot flue gas of discharging from boiler enters the back-shaped passage of the formation in the deduster casing 5 at the graviational interaction lower edge of air-introduced machine 23 deduster gas approach 3, when passing through the alkaline aqueous solution of casing 5 bottoms, the sulfur in smoke major part is dissolved in wherein, flue gas is warmmer simultaneously, produce a part of steam, flue gas and steam are during along back-shaped passage that plane clapboard and arc deflector constitute, constantly with plane clapboard, repeatedly collision takes place in arc deflector and cabinet wall, make dust in flue gas condense into particle, particle increases gradually, fall back to the taper dust chamber by gravity, also fall back in the taper dust chamber 11 after sulfur in smoke is water-soluble, be deposited on ash bucket 16, in 17, press ash discharge lever 12 again, top formula ash-valve 15 moves up in promoting, and the dirt slag is entered in the sedimentation basin 14, has realized the purpose of desulfurization and dedusting.
