Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, exhaust gas cleaner of the present invention, comprise bubbler and absorbing liquid container, described bubbler comprises inlet exhaust gas and bubbling pipe, described bubbling pipe one end is communicated with inlet exhaust gas, the other end stretches in absorbing liquid container, also comprises offgas outlet, described offgas outlet and absorbing liquid reservoir.Because bubbling pipe one end is communicated with inlet exhaust gas, the other end stretches in absorbing liquid container, and therefore tail gas is entered after in absorbing liquid container by bubbling pipe and purifies below liquid level, effectively prevent tail gas and leaks.Due to offgas outlet and absorbing liquid reservoir, the tail gas therefore after purification can enter next link from offgas outlet.
Described bubbler bottom is provided with water seal cylinder, and reaction vessel top is provided with the water sealed tank matched with water seal cylinder.Water seal cylinder coordinates with water sealed tank, forms effective water seal, can more effectively prevent tail gas from leaking.Water seal height is determined according to admission pressure.
Described offgas outlet is by tail gas escape pipe and absorbing liquid reservoir.Due to offgas outlet and absorbing liquid reservoir, the tail gas therefore after purification can enter next link from offgas outlet smoothly.
Also comprise plenum chamber, described plenum chamber is arranged between inlet exhaust gas and bubbling pipe.Plenum chamber can make bubbling pipe uniform air distribution.
Also comprise expand tube end plate, described therefore bubbling pipe is fixedly connected on plenum chamber by expand tube end plate.Expand tube end plate is evenly holed for expanded joint bubbling pipe.
Also comprise absorbing liquid feed tube and absorbing liquid drain pipe, described absorbing liquid feed tube is arranged in absorbing liquid container, and described absorbing liquid drain pipe is arranged in absorbing liquid container.
Also comprise cooling system, described absorbing liquid drain pipe is connected with the import of cooling system, and described absorbing liquid feed tube is connected with the outlet of cooling system.Absorbing liquid feed tube and absorbing liquid drain pipe can conveniently supplement and change the reactant liquor in absorbing liquid container, can also to carrying out heat exchange process by cooling system reactant liquor easily.
Also comprise discharging opening, described discharging opening is arranged on the below of absorbing liquid container.Discharging opening is outer row's product and the carbon black pellet washed out regularly.
Also comprise liquid-sighting glass to install on the reaction vessel.Liquid-sighting glass is for observing liquid level.
The principle adopting this device to carry out tail gas clean-up is: be added with absorbing liquid in absorbing liquid container during purification run, arranges Liquid level line, the Altitude control Liquid level line place of absorbing liquid according to purification requirement.The pH value of Liquid level and absorbing liquid is considered when system.200 degree, the carbon black tail gas of 2000pa enters plenum chamber by inlet exhaust gas, the effect of plenum chamber makes bubbling pipe 9 uniform air distribution.Bubbling pipe lower end is immersed in and absorbs about 150mm under liquid level, automatic liquid surface control, because gas pressure is greater than liquid level pressure, various bubbles is emerged from liquid level, bubble and absorbing liquid heat transfer in the process, mass transfer thus reach the object of cooling and dewatering, desulphurization and denitration, dedusting.Bubble goes out liquid level and breaks, up, is pooled to offgas outlet reaches purification object from the outside of bubbling pipe.In the process, former 200 degree of tail gas in bubbling pipe and 40 degree of tail gas after purifying carry out heat exchange by the bubbling pipe on absorbing liquid top, the exhaust temperature entered is reduced, the exhaust temperature of going out increases to over dew-point temperature, in order to avoid dewing corrosion pipeline, adopt the method to carry out heat exchange, do not need separately to add external heat source, saved the energy.The water sealed tank topped up with water of absorbing liquid container, the height of water seal guarantees that sealing tail gas is not revealed.Absorbing liquid feed tube and absorbing liquid drain pipe, connect external refrigeration system cools absorbing liquid, the heat of tail gas taken away.Liquid-sighting glass is for observing liquid level, and discharging opening is outer row's product and the carbon black pellet washed out regularly.Exhaust gas cleaner feature of the present invention is: be easy to manufacture, install easy to clean, up-down structure connects without bolt, good airproof performance, safe and reliable, the most important thing is, purification efficiency is high, can serialization, automation, standardization manufacture.
