Description
Technical field
The present invention relates to a kind of exhaust gas scrubber, specifically marine exhaust wash mill.
Background technology
With the development of shipping business, because it uses low-quality heavy oil, the SO2 and particulate matter of discharge contain marine low speed diesel engine
Amount will further increase.The technology for being presently used for removing marine exhaust SO2 and particulate matter mainly has waste gas to wash and using generation
Use fuel.Substitute fuel mainly has liquefied natural gas and Low Sulfur Fuel Oil, and compared with wet scrubbing technology, Low Sulfur Fuel Oil price is held high
Expensive, operating cost is high, and liquefied natural gas the key technology such as must store, transports and reveal and not yet solve, and application is less.Wet type is washed
The technology of washing is the mainstream technology of the strict Abgasgesetz of reply.
The type of marine diesel exhaust gas scrubber is mainly U-shaped packed tower, can meet SO2 removing requirement, also can
The larger particles of a part are removed, but require larger for obsolete vessel transformation, cost is added, is installed for new ship, it is also desirable to
Reserved larger space.For the demand of shipowner, development of new is efficient, is easily installed, is more suitable for the waste gas washing dress of ship
Put, be occupy ship washer market, solve China's current and future foreign-going ship free in and out each marine site in the world, promote China
Shipping industry goes to the world indispensable important measures.
In the prior art, main marine exhaust wet scrubbing technology mainly has：
Patent " a kind of exhaust emission joint removing means (201410374452.6) for two stroke diesel engine ", should
Patent is to remove SO2 and particulate matter using spraying technique, and turriform is packed tower, and the technology is using relatively broad in propagation
Wet scrubbing technology, it is higher to SO2 removal efficiency, but space-consuming is larger when real ship is installed.
Patent " a kind of tower desulfurization of ship tail gas one is except particle device and application method (201310344800.0) ", this is special
Profit is to remove SO2 and particulate matter using multiple filling layers and spray, and it is capable of the removing SO2 of greater efficiency and larger particle
Thing, but due to its multiple filling layers, resistance is increased, there is also installation question.
The content of the invention
It is an object of the invention to provide can efficiently remove SO simultaneously2It is straight with a kind of marine diesel of partial particulate thing
Column exhaust gas scrubber.
The object of the present invention is achieved like this：
A kind of marine diesel in-line arrangement exhaust gas scrubber of the present invention, it is characterized in that：Including washer tower body, cooling spray
Drenching layer, cleaning solution delivery pipe, the lower surface of washer tower body set exhaust gas inlet, and the upper surface of washer tower body sets waste gas to go out
Mouthful, the top of exhaust gas inlet sets the waste gas kuppe for making waste gas produce vortex, and chilling spray layer is arranged on waste gas kuppe
Top, chilling spray layer are sequentially arranged above three-level spraying layer, two level spraying layer, one-level spraying layer, and cleaning solution delivery pipe is set
Put in the outside of washer tower body and be respectively communicated with one-level spraying layer, two level spraying layer, three-level spraying layer and chilling spray layer, one
Demister is set in washer tower body space above level spraying layer.
The present invention can also include：
1st, washing water inlet is provided with cleaning solution delivery pipe, the bottom of washer tower body is provided with washing water out；
The upper strata manhole of maintenance is provided on washer tower body above demister, is set on the washer tower body by waste gas kuppe
Put lower floor's manhole for maintenance.
Advantage of the invention is that：The invention provides one kind to be easy to new ship installation and obsolete vessel transformation, while efficiently
Removing SO2With the wash mill of partial particulate.The device waste gas is entered in tower by washer bottom, by waste gas kuppe
Completely cut off liquid and flow into waste stack, while form strong vortice, change waste gas flow direction, reduce waste gas flow velocity, when increasing gas-liquid contact
Between, gas-liquid counter current is evenly improved SO2With the arresting efficiency of particulate matter, in addition, this device no-arbitrary pricing device, subtracts significantly
Lack resistance, the higher jet length of dependence, remove most of particulate matter.The device uses waste gas bottom inlet, no-arbitrary pricing, outer
Footpath is small, can be directly placed in ship chimney, enormously simplify installation procedure, be more suitable for ship.By with alkali lye system and
The cooperation of circulating pump system system, it is possible to achieve open type, enclosed and hybrid pattern.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Illustrate below in conjunction with the accompanying drawings and the present invention is described in more detail：
With reference to Fig. 1, marine diesel in-line arrangement exhaust gas scrubber of the present invention mainly includes：Washer tower body 1, waste gas enter
Mouth 15, waste gas outlet 9, washing water inlet 3, washing water out 2, demister 10, nozzle 11, one-level spraying layer 4, two level spray
Layer 5, three-level spraying layer 6, chilling spray layer 14, waste gas kuppe 13, upper strata manhole 8, lower floor's manhole 7, cleaning solution delivery pipe 12.
The top of exhaust gas inlet 15 is provided with waste gas kuppe 13, waste gas kuppe 13, and top is chilling spray layer 14, cooling
Spraying layer 14 is connected with cleaning solution delivery pipe 12, and spraying layer is once from top to bottom one-level spraying layer 4, two level spraying layer 5 and three
Level spraying layer 6, nozzle 11 are arranged on spraying layer, and demister 10 is arranged on waste gas outlet 9, and above each several part, which is all enclosed in, to be washed
Wash in device tower body 1, upper strata manhole 8 and lower floor's manhole 7 are arranged in washer upper and lower part.
With reference to Fig. 1, what the function of the wash mill was realized in：
Waste gas enters washer through exhaust gas inlet 15, flows into scrubbing section through waste gas kuppe 13 is circumferential, is disturbed through kuppe
Afterwards, vortex is formed, after spraying layer 4-6 and demister 10, is discharged through exhaust outlet 9.Sprayed by three-level, and waste gas is led
The distributed function of stream 13 pairs of waste gas of cover, increases gas-liquid contact time, makes gas-liquid counter current evenly, improve SO2 and particulate matter
Arresting efficiency.
This wash mill peculiar to vessel is in-line arrangement, and waste gas flows straight up through exhaust chimney, enters through exhaust gas inlet 15 and washes
Device is washed, effectively solves ship installation question.
For waste gas after exhaust gas inlet 15 enters washer, waste gas kuppe 13 can not only influence waste gas distribution, but also
Liquid can be prevented to enter chimney.Chilling spray layer 14 can not only cool down to waste gas kuppe 13, and can reduce
EGT.
By opening up upper strata manhole 8 and lower floor's manhole 7, it is possible to achieve to demister 10, and spraying layer at different levels and useless
Gas kuppe is repaired.
