Abstract

The utility model discloses a sprinkling desulfurizing tower, which comprises a main cylinder and an auxiliary cylinder, the upper ends of the main cylinder and the auxiliary cylinder are communicated with each other to form a converse U-shaped flue. The bottoms of the main cylinder and the auxiliary cylinder are respectively provided with a fume inlet and a fume outlet. A plurality of annular spray pipes are arranged in the middle of the inner cavity of the main cylinder, and water jets are distributed on all of the annular spray pipes. The sprinkling desulfurizing tower provided by the utility model is characterized in that each annular spray pipe is provided with a plurality of rotational flow plates arranged in a twist way. The sprinkling desulfurizing tower has good dust removing effect, and is suitable for desulfurizing and removing dust for fume exhausted by coal burning boilers or kilns.

Description

Spray desulfurizing tower

Technical field

The utility model relates to a kind of smoke eliminator.Specifically, be to be used for coal-burning type boiler or kiln institute smoke discharging are carried out the spray desulfurizing tower of desulfurization and dedusting.

Background technology

For eliminating the pollution that coal-burning type boiler or kiln institute smoke discharging are brought atmosphere, all can cleaner be installed usually at the exhaust opening of coal-burning type boiler or kiln.Cleaner commonly used is the spray type desulphurization tower.This spray type desulphurization tower contains main tube and secondary tube, and the bottom of major and minor tube has into and out of mouth, and their upper end is connected, thereby forms inverted U-shaped flue.Be provided with annular spray pipe in the main tube, be evenly equipped with water jet on the annular spray pipe.During work, utilize the moisture film that water jet sprayed on the annular spray pipe to carrying out desulfurization and dedusting by the flue gas in the main tube.Because dust in the flue gas is aloft by just sedimentation after soaking, and for the particulate that is not soaked as yet, does not still have the filtering effect.Therefore, the dust removing effects of this spray desulfurizing tower is relatively poor.

The utility model content

Problem to be solved in the utility model provides a kind of spray type desulphurization tower.This spray type desulphurization tower, good dedusting effect.For addressing the above problem, take following technical scheme:

Spray desulfurizing tower of the present utility model contains main tube and secondary tube, and the upper end of this master's tube and secondary tube is connected, to constitute the reverse U shape flue.Into mouth and outlet flue are arranged respectively at the bottom of main tube and secondary tube, and there are some annular spray pipes at main tube inner chamber middle part, is evenly equipped with water jet on the annular spray pipe.Be characterized in all having on each annular spray pipe the eddy flow plate of some layouts of shapes in the shape of a spiral.

In the main tube core pipe is arranged, this core pipe is to be erect shape and stands lumen centers at main tube, and the inside and outside limit of eddy flow plate is fixed together with the outer wall of core pipe and the inwall of main tube respectively.Said eddy flow plate is a granite slab.

Take such scheme, have the following advantages:

Because spray type desulphurization tower of the present utility model is provided with the eddy flow plate that some shapes are in the shape of a spiral arranged on its each annular spray pipe, when flue gas passes through the eddy flow plate from bottom to top, dust in the flue gas can stick on the eddy flow plate, and then is taken away by the water droplet on the eddy flow plate.So, flue gas is increased the multiple tracks filtration again, made dust removing effects and desulfurized effect improve greatly.Show that after tested dedusting and desulfuration efficiency are respectively up to more than 98% and 85%.

Description of drawings

Fig. 1 is a spray type desulphurization tower structure schematic diagram of the present utility model;

Fig. 2 is Figure 1A-A cross-sectional schematic through having amplified.

The specific embodiment

As shown in Figure 1, spray type desulphurization tower of the present utility model contains main tube 3 and secondary tube 2, and the upper end of this master's tube and secondary tube is connected, to constitute the reverse U shape flue.The bottom of main tube 3 and secondary tube 2 is processed with into mouth 9 and outlet flue 1 respectively.Main tube 3 inner chambers middle part is equipped with three annular spray pipes 8, is processed with some water jets 5 on the annular spray pipe 8 equably, on each water jet 5 nozzle is installed all.All be welded with admitting pipe joint 7 on each annular spray pipe 8, when this admitting pipe joint is communicated with running water pipe, by three annular spray pipes 8 and on the water of nozzle ejection can form three layers of moisture film.Advance the flue gas that mouth 9 is come in from main tube 3 bottoms, behind three layers of water film filtering, a part of dust is by filtering.

See Fig. 1 and Fig. 2, a plurality of eddy flow plates 4 all are installed on each annular spray pipe 8.These a plurality of eddy flow plates are granite slab, its installation method is, in main tube 3, a core pipe 6 is set, this core pipe is the setting shape and stands in the lumen centers of leading tube 3, a plurality of eddy flow plates 4 circumferentially are even layout along the core pipe, and their inside and outside both sides are fixed together with the outer wall of core pipe 6 and the inwall of main tube 3 respectively.So, flue gas contacts with the eddy flow plate 4 that squirts behind water film filtering again, has increased the multiple tracks filtration, makes dust removing effects and desulfurized effect improve greatly.
