Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of boiler chimney dust pelletizing system of the utility model embodiment, it comprises drainage arrangement 3, spray equipment, water pump 6, sampler 7, detector 8 and controller 9, admission line 2 is arranged on the bottom of chimney 1, drainage arrangement is arranged on the bottom of chimney 1 and is positioned at the below of admission line 2, flue gas after one-time dedusting enters chimney 1 from admission line 2, and discharge from the top of chimney 1, spray equipment to be arranged in chimney 1 and to be positioned at the top of admission line 2, can guarantee that the flue dust be discharged into the flue gas of chimney 1 from admission line 2 is effectively absorbed, spray equipment should not be installed too high, generally be positioned at the position from about chimney bottom 1mm, spray equipment is connected with the water pump 6 being arranged on chimney 1 outside, sampler 7 to be arranged in chimney 1 and to be positioned at the top of spray equipment, sampler 7 is connected with the detector 8 being arranged on chimney 1 outside, this sampler 7 is for online, gather the fume sample of chimney 1 exhaust outlet in real time, the dust concentration of fume emission is detected in real time for detector 8, the detector 8 of the present embodiment is connected with controller 9, the dust concentration information detected is sent to controller 9 by detector 8, controller 9 is connected with water pump 6, the dust emission standard value of flue gas is provided with in controller 9, and the real-time dust concentration of the chimney sent by detector 8 and dust emission standard value contrast, to judge whether just to regulate the flow of spray equipment, to guarantee that the dust concentration of chimney meets discharge standard.
The spray equipment of the present embodiment comprises horizontally disposed annular conduit 4 and multiple nozzle 5 be located on annular conduit 4, annular conduit 4 is connected with water pump 6, multiple nozzle 5 is evenly located on annular conduit 4, because chimney generally adopts taper shape, therefore its structure of annular conduit of adopting of the present embodiment and chimney match, the madial wall can pressing close to chimney is better arranged, to increase spray face, the cross section of chimney can spray flue gas comparatively all sidedly, guarantee all effectively to be contacted with shower water by the flue gas of chimney, with by the low as far as possible absorption of shower water flue dust wherein, and then raising dust removing effects.It is to be noted: spray equipment of the present utility model for arranging other structure as square or erose water pipe, and can also arrange multiple nozzle on water pipe; Also can be: water pipe is vertical and many that arrange along flue dust circumference, and arranges multiple nozzle on every root water pipe.
Preferably, in order to improve the effect of flue dust final dusting further, the annular conduit 4 of the present embodiment is many, is spaced apart 1-2m between adjacent two annular conduits 4.Because the flue gas flow direction in chimney is straight up, if the spray mode of the level of employing, then can produce larger resistance to the discharge of flue gas, flue gas is caused not discharge in time, and if any adopting downward spray mode, shower water then can not be made effectively to contact with flue gas, therefore, the nozzle 5 of the present embodiment is inclined upwardly setting, and spray direction upwards, the resistance to flue gas can be reduced, and the shower water of multiple nozzle focuses in centre, under gravity, shower water falls into chimney bottom from centre, effectively can contact with flue gas, to guarantee dust removing effects.Preferably, nozzle 5 is inclined upwardly 30-50 °, is preferably 35-45 °, and its dust removing effects is best.
The drainage arrangement 3 of the present embodiment is self-operated type drainage arrangement, it comprises drainpipe and self-contained pressure regulator, drainpipe is connected with the bottom of chimney, self-contained pressure regulator is connected with drainpipe, the present embodiment should guarantee that the liquid level of ponding bottom chimney 1 should lower than the lower pipe face of admission line 2, when the ball float of self-contained pressure regulator detects the lower pipe face of the liquid level of the ponding bottom chimney 1 soon close to admission line 2, self-contained pressure regulator is opened and the ponding in chimney is discharged in time through drainpipe.
The utility model also provides a kind of dust collection method based on above-mentioned boiler chimney dust pelletizing system, in chimney emission process, flue gas after one-time dedusting enters chimney by the admission line of chimney bottom, and undertaken spraying with dedusting by the spray equipment being arranged on chimney inside, simultaneously, the flue gas of sampler Real-time Collection chimney exhaust ports, detector detects the dust concentration of the flue gas that sampler gathers in real time, and detected dust concentration information is sent to controller, dust emission standard value is preset with in controller, when detected dust concentration is greater than dust emission standard value, controller controls water pump to tune up the flow of spray equipment, contact better with shower water to make flue gas, increase dust removing effects, to guarantee that the flue gas that chimney is discharged meets national standard, otherwise the flow of spray equipment is constant, now, the flue gas keeping original spray flux that chimney can be made to discharge meets national standard.
In order to reduce the resistance of shower water to fume emission, and improve dust removing effects, the nozzles inclined upwards 30-50 ° of spray equipment sprays.
The boiler chimney dust pelletizing system that the utility model embodiment provides and dust collection method, be specially adapted to the boiler chimney in sugar refinery, in chimney inside, spray equipment is set, and adopt sampler and detector with the dust concentration of Real-Time Monitoring smoke stack emission, and the flow of spray equipment is adjusted in time according to the dust concentration of chimney, effectively contact with shower water to make flue gas, improve dust removing effects, the dust concentration of boiler chimney fume emission is made to meet national standard, chimney dust removal system architecture of the present utility model is simple, relative to the scheme of newly-increased sack cleaner, its cost is lower.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
