Description
Technical field
This utility model relates to a kind of coal-burning boiler desulfurization demister.
Background technology
Spray is the mode of a kind of common absorption solubility waste gas in current coal-burning boiler dust arrester, but can produce time due to spray more small to present vaporific droplet 10, easily flow along with air-flow rises, wherein dissolve the waste gas of a part, if the droplet 10 of this part is not removed, influence whether the treatment effeciency of waste gas. Therefore generally demister can all be added above sprinkling equipment, as shown in Figure 3, demister is made up of the passage much bent, droplet 10 along with in air-flow uphill process due to inertia, got rid of on conduit wall at passage kink 9 place, thus removing the droplet 10 of this part.
But, in demister use procedure, liquid film 6 on conduit wall is easily more walked with on aerodynamic-laid web, again droplet 10 is formed so that the decreased effectiveness of dehydration device, means general at present are the modes that have employed two-stage demister, as shown in Figure 4, be namely sequentially arranged above first demister the 81, second spraying layer the 72, second demister 82 at sprinkling equipment 71, thus reduce as much as possible from demister droplet 10 out with exhausted air quantity.
Current ejecting liquid absorbs the precipitation often producing some solid-states in waste gas after impurity, and precipitation overstocks after on demister for a long time, it is easy to the passage of blocking demister, brings hidden danger to production safety. Simultaneously because the spray of two-stage demister needs the lower surface of the upper and lower surface and the second demister 82 that spray the first demister 81 is sprayed, so the very big cost of water consumption needed is also higher. Additionally, in air-flow after two-stage dehydration, still can there are some water solublity waste gas brought out by droplet 10, such as sulfur dioxide, nitrogen dioxide etc., the gas of this part is easily caused by the corrosion of blower fan. Further, if too much steam is got rid of from chimney, " chimney rain " can even be formed.
Summary of the invention
The purpose of this utility model is to provide the coal-burning boiler desulfurization demister of a kind of highly effective and safe.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of coal-burning boiler desulfurization demister, including housing, be arranged on described lower housing portion air inlet, be arranged on the gas outlet of described case top, the spraying layer being arranged in described housing, be arranged on above described spraying layer except mist assembly, described except mist assembly includes demister and is arranged on the winding-up assembly of the blast pass of downward interval in a pulsed fashion above described demister.
Preferably, multiple winding-up arms that Open Side Down that described winding-up assembly includes the many injection tubes being set in parallel in same level, is arranged in described injection tube, one end of described injection tube is closed, and the other end stretches out described housing and is provided with gas storage bag, draws together pulse valve and controls the controller of described pulse valve.
It is further preferred that described winding-up assembly also includes pulse control instrument, described pulse control instrument electrically connects with each described controller, and described pulse control instrument controls the pulse valve in every injection tube by described controller and produces blast pass in turn.
Preferably, described demister includes the blade of support and the setting multiple bendings on the bracket being horizontally set in described housing, forms the gas channel of bending between adjacent two described blades.
It is further preferred that the waveform bent passage that described gas channel is even thickness.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that
Owing to this utility model adopts winding-up assembly downward interval blast pass in a pulsed fashion, will be attached to the water droplet on gas channel before being raised air-flow and taking passage out of, it is blown away downwards, can effectively prevent the water droplet being attached on gas channel from continuing up, thus improve the absorption efficiency of emission-control equipment, air pulse can will be attached to the precipitation removing of the solid-state on demister passage simultaneously, it is possible to effectively prevents demister from blocking, also can save substantial amounts of water resource simultaneously.

Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, this utility model is further described:
Embodiment one: shown in accompanying drawing 1-2, a kind of coal-burning boiler desulfurization demister, including housing 1, be arranged on the air inlet of housing 1 bottom, the gas outlet 2 being arranged on housing 1 top, the spraying layer 3 being arranged in housing 1, be arranged on above spraying layer 3 except mist assembly, except mist assembly includes demister 4 and is arranged on the winding-up assembly 5 of the blast pass of downward interval in a pulsed fashion above demister 4. Interval is touched the liquid that the air-flow blown can effectively will be attached on demister 4 wall and is blown away downwards, it is prevented that water miscible waste gas follows liquid through demister.
Multiple winding-up arms 52 that Open Side Down that winding-up assembly 5 includes the many injection tubes being set in parallel in same level 51, is arranged in injection tube 51, one end of injection tube 51 is closed, and the other end stretches out housing 1 and is provided with gas storage bag, draws together pulse valve 53 and controls the controller 54 of pulse valve 53.Winding-up assembly 5 also includes pulse control instrument 55, and pulse control instrument 55 electrically connects with each controller 54, and the pulse valve 53 that pulse control instrument 55 is controlled in every injection tube by controller 54 produces blast pass in turn. Winding-up in turn can improve the work efficiency of winding-up assembly 5, removes the liquid on demister 4 wall better, and air pulse can will be attached to the precipitation removing of the solid-state on demister 4 wall simultaneously, it is possible to effectively prevents demister from blocking.
Demister 4 includes the support 41 and the blade 42 of the multiple bendings being arranged on support that are horizontally set in housing 1, forms the gas channel 43 of bending between adjacent two blades 42. Gas channel 43 is the waveform bent passage of even thickness.
