Description
Technical Field
The invention relates to the technical field of tail gas purification of marine diesel engines, in particular to a novel marine SO 2 And a PM integrated removing device.
Background
With the rapid development of world trade, the amount of goods in and out of countries has increased dramatically, and maritime transportation is responsible for more than 90% of the goods in the world. Diesel engines are widely used as marine propulsion power plants due to their good performance. At present, the ship engine mainly takes inferior heavy oil as fuel, and the tail gas contains a large amount of SO 2 . International Maritime Organization (IMO) and environmental protection department of china for ship SO 2 Has strict limiting standards. In addition, the exhaust gas discharged by ships contains a large amount of PM, and the large amount of PM discharge can cause respiratory system diseases of human bodies and bring great harm to human health and marine ecology. Various scientific research institutions at home and abroad are dedicated to ship exhaust SO 2 And PM removal technical studies.
A great deal of research shows that wet scrubbing of SO from marine exhaust gas 2 And PM has certain removal effect. Due to SO 2 Has better solubility, SO the wet washing technology can realize SO 2 In the wet washing process, the washing liquid forms mist-like small droplets after being sprayed out from a nozzle, and the small droplets collide with PM particles in the exhaust gasThe nucleation of colliding with the condensation, finally gather, thereby realize the high-efficient desorption of PM, the desorption efficiency of the pure utilization traditional scrubbing tower PM is lower, it sets up the vice scrubbing tower to be generally adopting beside the main washing for the desorption efficiency that improves PM, thereby realize the high-efficient desorption of PM, but the setting of vice scrubbing tower can obviously increase the volume of scrubbing tower, the washing liquid after vice scrubbing tower takes off the granule is seriously polluted simultaneously, later with the washing liquid of serious pollution and comparatively overtightened desulfurization washing liquid mix together can obviously improve the replacement frequency of washing liquid, thereby increase the operation work energy consumption of washing system, because the boats and ships space is narrow and small, therefore small-size and energy-conserving washing system is vital to the green low carbon operation of boats and ships, many scholars have carried out research and design to boats and ships wet scrubbing system, but all have certain defect in the technology.
In the integrated device and method for desulfurization, denitrification and dust removal of ship with the application number of 202210202292.1, NO in ship exhaust gas is realized by an SNCR device x Then the SO in the ship exhaust gas is realized by washing 2 The high-efficiency removal of PM and the obvious problems in the application of the modified device, firstly, the temperature of the ship exhaust gas is low, and NO can not be realized by the SNCR technology x Secondly, the efficient removal of PM cannot be achieved in this patent by a simple scrubber alone.
In the patent of 202120951616.2, the comprehensive absorption tower is used to desulfurize, dedust and decarbonize the tail gas of ship, and the carbon dioxide analyzer separates out carbon dioxide and lean liquid from the decarbonized rich liquid to realize the separation of sulfur oxide, particle and CO in waste gas 2 The removal is efficient. The first liquid collecting section and the second liquid collecting section of the device cannot be completely separated in practical application, the first liquid collecting section and the second liquid collecting section are mixed, ship washing wastewater has a clear discharge standard, and the washed wastewater can be discharged outside only after being treated. In addition, the absorption liquid mixed by alcohol amine belongs to toxic liquid, and can be applied to ships in various aspectsEvaluation and CO 2 The desorption temperature of (2) is high and close to boiling, so that not only can a large amount of heat energy be required, but also a large amount of water resources can be consumed.
In summary, the existing ship SO 2 Has a plurality of problems with PM removing devices, develops a set of ship SO with small volume, low energy consumption and simple structure 2 And an integrated device for efficiently removing PM is necessary.
Disclosure of Invention
The invention provides a novel ship SO 2 And an integrated device for efficiently removing PM, and provides detailed composition, design principle and working flow of the device.
In the invention, SO is realized by utilizing a wet washing technology 2 And efficient removal of PM.

Novel ship SO of the invention 2 And the specific working process of the PM high-efficiency removal integrated device is as follows:
(1) The high-temperature exhaust gas discharged by a marine diesel engine moves downwards in a Venturi scrubber in a washing tower, a PM removing and washing spray device is installed in the Venturi scrubber, so that the exhaust gas can be efficiently removed in the Venturi scrubber, the exhaust gas discharged from the Venturi scrubber runs upwards on the outer layer of the washing tower, when the exhaust gas passes through a primary demisting device, a PM washing liquid is effectively separated from the exhaust gas, the exhaust gas continues to go upwards, the PM washing liquid passes through a filtering device below the Venturi scrubber, the PM washing liquid after filtering dregs is recycled to a Venturi nozzle again for carrying out the next working process, a density meter is installed on a PM washing liquid pipeline and used for monitoring the water quality of the PM washing liquid, when the density of the PM washing liquid is too high, part of the PM washing liquid is gradually discharged into a wastewater treatment device, and meanwhile, corresponding fresh liquid is supplied to the PM washing liquid pipeline.
(2) The waste gas passing through the first-stage demisting device continuously goes upward, passes through the ventilation cap above the clapboard, then goes upward to the packing layer above, and simultaneously SO 2 SO sprayed from cleaning solution spraying layer 2 The cleaning liquid also falls to the filling layer, and SO is completed in the filling layer 2 The removal process is performed when SO is shielded by the gas permeable cap 2 After the scrubbing liquid has fallen from the packing layer, SO 2 The cleaning solution only falls to the upper part of the clapboard, but not to the lower part of the clapboard and the SO above the clapboard 2 The washing liquid is transferred to SO again by a water pump 2 Washing the layer for the next cycle of SO 2 Removal of in SO 2 The washing liquid is transported to SO 2 SO can be detected by the sensor in the process of spraying the cleaning solution on the layer 2 The pH and density of the wash liquor are monitored and when conditions are not met, a portion of the SO is removed 2 The washing liquid is gradually discharged into the wastewater treatment device, and meanwhile, the water replenishing device supplies SO to the washing liquid 2 The washing liquid spraying layer supplies corresponding fresh liquid. Has removed SO 2 The waste gas continuously goes upwards to pass through a secondary demisting device, in the secondary demisting device, moisture in the waste gas is removed, and then SO 2 And discharging the exhaust gas after PM treatment from the upper part of the washing tower.
Compared with the prior art, the invention has the following advantages:
(1) In the invention, SO is removed 2 The washing liquid and the washing liquid for removing PM share one set of washing liquid supply system, but the two liquids are separated in the washing tower, because the PM washing liquid can remove a large amount of PM, SO 2 The scrubbing liquid is relatively clean even after multiple cycles, which significantly reduces SO 2 The frequency of the renewal of the washing liquid, at the same time, greatly reduces the clogging rate of the packing. And because the main effect of the PM washing liquid is the removal of PM, the washing liquid can be repeatedly washed for many times, so that the integral replacement and replacement frequency of the washing liquid can be greatly reduced, the water consumption of the system can be greatly reduced, and the energy consumption is obviously reduced accordingly.
(2) Install the venturi scrubber and make the outward appearance of scrubbing tower more regular in the scrubbing tower, obviously reduce the installation space of scrubbing tower to greatly promote its installation and maintenance convenience at boats and ships.
