The invention has the beneficial effects as follows: screen collector surrounding is arranged multiple cyclone dust collectors, reduce the floor space of cleaner greatly, multiple cyclone dust collectors are together in parallel and carry out first time dedusting to tail gas, save the time, again unified water curtain dedusting is carried out to the tail gas through cyclone dust collectors, ensure that purification efficiency; Because one of raw materials for production that the liquid of spray is used: molasses alcohol fermentation liquid needs to carry out preheating thawing and just can spray, so the shell of this dust arrester have employed double-decker, the high temperature of device inside is utilized to carry out preheating to the molasses alcohol fermentation liquid passed in cavity pocket of outer cover, be transferred to spray equipment again, such liquid sprayed out can directly reflux to the production equipment of upstream after mixed fertilizer granule, reaches the object of economize energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of fertilizer tail gas dust cleaning apparatus of the present invention.
Fig. 2 is cyclone inside top figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to description word to make those skilled in the art.
As shown in Figure 1 and Figure 2, a kind of fertilizer tail gas dust cleaning apparatus, it comprises the space of housing 3 and its inside, and enclosure interior arranges screen collector 1 and is distributed in 2 cyclones 2,2 ' of described screen collector 1 surrounding; Housing is provided with air intake 31, gas outlet 32 and loading head 33, and housing gas outlet 32 is connected by pipeline 8 with blower fan 7; Cyclone comprises cyclone admission line 21, cyclone discharge duct 22 and cyclone removing ash pipeline 23; Screen collector 1 comprises the leakage fluid dram 14 of screen collector air inlet 11, screen collector gas outlet 12, liquid-jet device 13 and bottom; Liquid-jet device is one piece of high-voltage probe, pressure is 1500bar, environment-friendly high-efficiency, its front end arranges a umbrella baffle plate 15, its umbrella baffle plate height is 20cm, radius is 40cm, and this baffle plate distance probe distance is 15cm, can ensure that liquid can form the complete liquid film layer blocking screen collector cross section in splash after umbrella baffle plate 15 with this understanding; Cyclone admission line 21 is connected to the air intake 31 of housing parallel to each other, and described cyclone outlet pipe 22 is connected to corresponding screen collector air inlet respectively, and the gas outlet 32 of housing is positioned at case top, and screen collector gas outlet 12 is communicated with; Be provided with the water curtain baffle plate 16 that multiple height is straggly between described screen collector air inlet 11 and described screen collector gas outlet 12, all there is the inclination angle of downward 10 ° of level in water curtain baffle plate 16, facilitates liquid flow; Cyclone removing ash pipeline 23 passes into the loading head 33 of described housing, screen collector leakage fluid dram 14 is connected to raw materials recovery pipeline, the liquid of liquid-jet device spray is molasses alcohol fermentation liquid, molasses alcohol fermentation liquid is the one of chemical fertilizer production raw material, now be used as the fluid of water curtain dedusting, then can be communicated in raw material liquid pool after being mixed with chemical fertilizer granule and carry out chemical fertilizer production.
The cavity that housing comprises outer wall, inwall and limited by this outer wall and inwall, outer wall makes by pressing from both sides glass fibre cotton in stainless steel iron sheet, this material thermal conductivity is low, sound-absorbing effect is good, therefore both can ensure that the heat in housing was not wasted, also can completely cut off the noise sent when dust arrester runs; Inwall is the alloy material of 3-5mm by thickness, outer wall is provided with and with the entrance 34 of this cavity connects and 35 can be exported, molasses alcohol fermentation liquid is communicated to described entrance 34, and the thermal energy radiation through high-temperature gas flows out from outlet 35, and described outlet 35 is connected with liquid-jet device 13 by mozzle.
Housing comprises the back taper shell of the conical shell on top, the tubular shell at middle part and bottom, and air intake is arranged on housing central section, and loading head is arranged at the bottom of the cone of back taper shell.
Cyclone admission line is the pipeline that one section of sectional dimension gradually changes, and can accelerate air-flow mobility.
Bottom loading head or sidewall be provided with the opening 331 can discharging gleanings, be provided with butterfly valve herein, be convenient to control dust discharge.
Respectively and be provided with fixture 4 between housing, the equipment that ensure that keeps firm under high flow rate gas impacts for screen collector and cyclone.
Be fixed with mounting bracket 5 at housing exterior walls, it adopts crashproof reinforcing bar to be made, and support is provided with the cross bar that many rows trample for people, facilitates workman to check dust arrester.
During the work of this equipment, the air being mingled with chemical fertilizer granule enters housing through air intake, then enter in cyclone dust collectors by cyclone admission line in parallel, at this moment air directly enters cyclone blast pipe, and the large chemical fertilizer granule of relative weight is subject to circle mental power function, circle round in cyclone fuselage, along with the air being mingled with dust constantly enters in cyclone, air and chemical fertilizer granule are pushed to cyclone blast pipe and cyclone removing ash pipeline respectively.Because cyclone separator can only be separated the particle that diameter is greater than 5 microns, enter in screen collector together with air so contain the chemical fertilizer granule that diameter is less than 5 microns.
In the process of removal of impurities, because chemical fertilizer granule is obtained by slurry-spraying pelletizing technique, so a large amount of heat energy can be carried, cavity be in the housing provided with can with the entrance and exit of this cavity connects, molasses alcohol fermentation liquid is communicated to described entrance, thermal energy radiation through high-temperature gas flows out from described outlet, find by measuring, through the molasses alcohol fermentation liquid of heat exchange, 73 DEG C can be risen to from original 25 DEG C of normal temperature, now molasses alcohol fermentation liquid melts completely, liquid-jet device is delivered to by catheter, during high-pressure nozzle running, the liquid that high-pressure nozzle spouting velocity is exceedingly fast, when liquid runs into umbrella baffle plate, liquid leaves to surrounding, thus form one liquid barrier, water curtain dirt pocket is separated, when the air being mingled with small chemical fertilizer granule moves to housing outlets, air is directly through liquid barrier, small chemical fertilizer granule is then left in liquid, and the water curtain baffle plate in screen collector also can form cascade, thus magazins' layout is carried out to air, the liquid used due to water curtain dedusting is molasses alcohol fermentation liquid, it itself is one of raw material of chemical fertilizer production, so the molasses alcohol fermentation liquid being mingled with chemical fertilizer granule is connected to raw materials recovery pipeline through screen collector leakage fluid dram, achieve the repeatedly utilization of material, economize in raw materials.
Although embodiment of the present invention are open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
