Description

A kind of chimney flue type reactor

Technical field

The utility model relates to a kind of chimney flue type reactors.

Background technique

In conventional lime/lime stone-gypsum wet desulphurization system, often due to the load acute variation of boiler, or Person's boiler soot-blowing causes entrance sulfur dioxide concentration sharply to increase, and no effective means controls sulfur dioxide in moment, leads Cause short-term outlet sulfur dioxide (SO2) emissions exceeded.In addition, moisture content is easy evaporation to lime stone slurry used in desulfurization under high temperature environment, enter Mouth flue has fouling possible, and gas approach, which returns slurry, also fouling risk.In addition, slurries return slurry seriously.Reflux is to blower in flue It will cause harm.

Utility model content

The purpose of this utility model is that overcoming defect existing in the prior art, a kind of chimney flue type reactor is provided, Entrance sulfur dioxide concentration when sharply increasing can transient absorption, quickly reduce outlet sulfur dioxide concentration, flexible function is variable； And gas approach fouling can be prevented.

To achieve the above object, the technical solution of the utility model is to design a kind of chimney flue type reactor, including chimney flue type The aerosol being connected with a flue injection entrance, aerosol injection are at least arranged in chimney flue type reactor shell for reactor shell Its surface at flue gas air inlet in chimney flue type reactor shell is arranged in entrance, and aerosol sprays inlet setting and chimney flue type The fixed adjustable aerosol spraying system of frequency conversion of reactor shell；It is located in the middle part of chimney flue type reactor shell along smoke movement direction and sets At least one cooling water inlet being connected with flue is set, is located at chimney flue type reactor shell end along smoke movement direction and is arranged At least one cooling water outlet being connected with flue also sets up at least one manhole in chimney flue type reactor shell.Using general Flue configures efficient three Fluid sprayer (reactant, water, compressed air), by slurries using independent spraying system as reactor Lime stone (CaCO₃) the ultimate attainment atomization of slurries is 100 μm hereinafter, making exceeded sulfur dioxide transient absorption, thus quickly reduction outlet Sulfur dioxide concentration.Moisture content is easy evaporation to slurries under high temperature environment, and gas approach has fouling possible, and gas approach, which returns slurry, also to be had Fouling risk.To prevent gas approach fouling serious, spraying system is that frequency conversion is adjustable, not exceeded in entrance sulfur dioxide concentration In the case of, frequency can be reduced, is closed to slurry valve, flushing is done and uses.Simultaneously under inlet flue gas accident conditions, atomization system can be with Frequency is increased, air supply is increased, atomizing effect is improved, flue-gas temperature is reduced to nominal situation in moment.

Further technical solution is that aerosol spraying system includes being fixed on chimney flue type reactor shell inner wall Support tube, is fixedly installed at least one three Fluid sprayer on support tube, three Fluid sprayers include inlet pipe road, inlet pipeline and into Air pipe, variable frequency pump is respectively set on inlet pipe road, inlet pipeline, and air inlet pipeline connects compressed air reservoir.Inlet pipe road, into Valve in water lines and air inlet pipeline manually controls opening and closing, and pump is frequency conversion, realizes grout absorption, inflow and air inflow Control (according to different operating conditions determine into amount).

Further technical solution is that ramp, the lowest part in ramp and suction is arranged in chimney flue type reactor shell bottom interior wall Tower is received to be connected.It is arranged by the ramp of housing bottom, so that cooling water directly flow to absorption tower certainly.

Further technical solution is that the size of two ends of chimney flue type reactor shell is less than chimney flue type reactor enclosure Size in the middle part of body, two ends of chimney flue type reactor shell pass through the chimney flue type reactor shell of ladder and rectangular housing shape Middle part transition.Chimney flue type reactor and flue do step design, and anti-backflow causes damages to blower.

Further technical solution is, chimney flue type reactor shell rectangular frame formula and is arranged outside flue, chimney flue type Several supports are fixedly installed below reactor shell, a pressure tap is arranged in its side of chimney flue type reactor shell；Chimney flue type Two ends of reactor shell are detachable respectively to be arranged the first expansion joint and the second expansion joint, chimney flue type reactor shell inner wall Upper fixed setting interior support posts, interior support posts are arranged close to the first expansion joint or the second expansion joint.

Advantages and beneficial effects of the utility model lie in that can be inhaled moment when entrance sulfur dioxide concentration sharply increases It receives, quickly reduces outlet sulfur dioxide concentration, spraying system is that frequency conversion is adjustable, in the not exceeded feelings of entrance sulfur dioxide concentration Under condition, frequency can be reduced, is closed to slurry valve, flushing is done and uses；Using using flue as reactor, using independent spraying system, Efficient three Fluid sprayer (reactant, water, compressed air) is configured, is 100 μm by the ultimate attainment atomization of slurries lime stone (CaCO3) slurries Hereinafter, making exceeded sulfur dioxide transient absorption, to quickly reduce outlet sulfur dioxide concentration.Slurries moisture content under high temperature environment It is easy evaporation, gas approach has fouling possible, and gas approach, which returns slurry, also fouling risk.To prevent gas approach fouling serious, Spraying system is that frequency conversion is adjustable, in the case where entrance sulfur dioxide concentration is not exceeded, can reduce frequency, is closed to slurry valve, Flushing is done to use.Simultaneously under inlet flue gas accident conditions, atomization system can increase frequency, increase air supply, improve mist Change effect, flue-gas temperature is reduced to nominal situation in moment.Valve on inlet pipe road, inlet pipeline and air inlet pipeline is hand Dynamic control opening and closing, pump is frequency conversion, realize grout absorption, inflow and air inflow control (according to different operating conditions determine into Amount).Water fender is set near three Fluid sprayers, can prevent slurries from returning slurry serious, while entrance avoids slurries from returning slurry too far. Chimney flue type reactor and flue do step design, and anti-backflow causes damages to blower.
