Technical field
The utility model belongs to technical field of waste gas treatment, is related to a kind of exhaust gas washing tower..
Background technology
Many exhaust-gas treatment fields can all use exhaust gas washing tower, for example：Marine exhaust process, desulfurization exhaust-gas treatment etc. are led
Domain.In particular with the enhancing of environmental consciousness, waste gas emission standard is gradually strict, for example：MARPOL pacts supplemental provisions VI specify,
From 1 day January in 2015, the ship in emission control area (ECA) is navigated by water, it is necessary to which combustion of sulfur amount is equal to or less than 0.10% (m/
M) Low Sulfur Fuel Oil, at the same allow ship use approved emission-reduction technology, condition be SO2 discharge be equivalent to burning be equal to or it is little
In 0.10% Low Sulfur Fuel Oil.
Therefore increasing research and development institution is put into the middle of the research and development of exhaust gas cleaning system.Waste gas is entered before scrubbing tower
It is required for through waste gas intake, intake carries out cooling process to waste gas, can improve follow-up clean result, makes exhaust-gas treatment
Fully.For marine exhaust process, investigation is currently in pilot-scale or the marine exhaust desulfurizer of trial sale finds, each public affairs
The waste gas incorporation way of department is not quite similar.
A kind of common air inducing mode is the air inducing mode of venturi primary cooling.Principle is：Closing is arranged on flue collector
On valve, by waste gas by after Venturi scrubber, in being incorporated into scrubbing tower.The advantage of which is that waste gas is entering de-
Sufficiently lowered the temperature before sulfur scrubber tower, improved the desulfuration efficiency of follow-up desulfurizing tower.But because being bypass design, desulfurization washing
Tower need take space it is larger, limited space application (for example：Ship), the recondition expense that can cause equipment is held high
It is expensive.
Utility model content
The purpose of this utility model is, according to the deficiencies in the prior art, there is provided a kind of floor space is little, exhaust-gas treatment is filled
The scrubbing tower for dividing.
The technical solution of the utility model is：Spiral-flow plate-type exhaust gas washing tower, including scrubbing tower body, the scrubbing tower sheet
Body top is provided with exhaust outlet, and scrubbing tower body lower section is provided with air inlet, along direction from air inlet to exhaust outlet, scrubbing tower sheet
In vivo portion includes waste gas diversion section and waste gas washing section；The waste gas washing section is provided with emission-control equipment, and the waste gas is led
Stream section is provided with board-like flow-guiding structure；The board-like flow-guiding structure includes column and the deflector being arranged on column.
Preferably：Water conservancy diversion uprights vertical scrubbing tower bottom is arranged.
Preferably：Deflector is spiral platy structure, along air inlet to the direction of exhaust outlet, is helically risen.
Preferably：The edge of deflector is contacted with washing inner wall of tower.
Preferably：From exhaust outlet to the direction of air inlet, emission-control equipment includes：Cleaning pipe, demister, spray
Pipe, Washing spray nozzle and cooling nozzles；Scrubbing tower body bottom portion is provided with least one leakage fluid dram.
Preferably：Air inlet is one or more.
The beneficial effects of the utility model are：The air inducing part-structure inside scrubbing tower is improved, specifically：(1) set
Board-like flow-guiding structure is counted, the lower surface of deflector has been touched in waste gas uphill process first, i.e., has been held towards one of air inlet
Face, the setting of deflector can change the rising flow direction of waste gas.Under conditions of identical lifting height, this structure is extended
The rise time of waste gas, so as to increase the wash time of waste gas, so as to improve detersive efficiency.(2) selecting and purchasing spiral type flow guide plates, can
Make waste gas spiral, the flow direction of regular waste gas.(3) cleaning solution spray in the upper surface of deflector, pair with deflector lower surface
The high-temp waste gas cooling on basis, reaches the effect of cooling before washing.(4) traditional induced draft structure is compared, board-like flow-guiding structure is accounted for
Space is little, is limited little by space, is more conducive to apply under conditions of limited space.

Specific embodiment
Specific embodiment of the present utility model is conducted further description below with reference to accompanying drawing.
As shown in figure 1, spiral-flow plate-type exhaust gas washing tower, including scrubbing tower body 1, the top of the scrubbing tower body 1 is arranged
Have an exhaust outlet 2, scrubbing tower body lower section is provided with air inlet 3, along guiding from air inlet 3 to exhaust outlet 2, in scrubbing tower body 1
Portion includes waste gas diversion section and waste gas washing section.Waste gas Jing air inlets 3 are entered inside scrubbing tower body 1, wherein waste gas diversion section
Play waste gas water conservancy diversion drainage；Waste gas washing section plays waste gas washing, that is, exhaust-gas treatment effect.
Waste gas washing section is provided with emission-control equipment, can arrange emission-control equipment, example according to the demand of exhaust-gas treatment
Such as, in the present embodiment, from exhaust outlet 2 to the direction of air inlet 3, emission-control equipment includes：Cleaning pipe 401, demister 402,
Shower 403, Washing spray nozzle 404；The bottom of scrubbing tower body 1 is provided with least one leakage fluid dram 405.
Waste gas diversion section is provided with board-like flow-guiding structure；Board-like flow-guiding structure specifically includes column 5 and is arranged on column 5
Deflector 6.
Used as a kind of preferred structure, the vertical washing column bottom of column 5 is arranged.
The effect of deflector 6 is the flow direction for guiding waste gas, and deflector 6 is spiral platy structure, along air inlet 3 to exhaust
The direction of mouth 2, helically rises.In addition, deflector 6 may also take on other shapes, for example：It is inclined with respect to column 5
Shape, thus it is possible to vary the flow direction of waste gas, increases the stroke of waste gas.
Used as a kind of preferred structure, the edge of deflector 6 is contacted with the inwall of scrubbing tower body 1.Waste gas is avoided as far as possible from leading
Gap between stream plate 6 and the inwall of scrubbing tower body 1 flows up, it is ensured that waste gas is fully contacted with deflector 6.
