Abstract
The invention discloses a dust collecting device used in production of monoammounium phosphate. The device mainly comprises a washing solution pipe, a nozzle, a snap ring, nuts and a bolt, wherein, the nozzle is screwed in the washing solution pipe and is provided with the snap ring, the snap ring is provided with one nut, the washing solution pipe is provided with the other nut, and fixed connection between the washing solution pipe and the nozzle is realized through connection between the bolt and the nuts. The dust collecting device provided in the invention uses the bolt for fixed connection, so reliable connection is achieved, effective collection of dust is realized, and washed and collected fine dust can be recycled after air drying. Effective connection between the nozzle and the washing solution pipe is realized in the invention, which enables a washing scope to be enlarged, a recovery rate of fine dust in tail gas to be increased and environmental pollution to be reduced.
Description
Technical field
The invention belongs to the MAP production technical field, particularly a kind of dust collecting for MAP production.
Background technology
Producing MAP adopts the circulating water wash gathering-device to collect from the phosphorus ammonium dust of tail gas drift usually, this gathering-device is comprised of washing lotion tube and nozzle, washing lotion tube is steel pipe, the nozzle material is poly-fluorine ethylene, its connected mode is for being threaded, because the washing lotion tube of dust collecting is two kinds of different materials with nozzle, long-time running under the cleaning solution temperature 50 C, its coefficient of expansion is different, and because of nozzle threads upper, the liquid flow path direction is downward, and the power effect of being hit causes nozzle easily to come off, and poly-fluorine ethylene nozzle often comes off, can cause cleaning solution to fling along pipe, the area that contacts with tail gas reduces, and washs out tiny dust just few, like this, the MAP dust drifts about everywhere, do not reach clean result, both wasted product, caused again environmental pollution.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of dust collecting for MAP production is provided, solved the interconnection technique difficult problem of washing lotion tube and nozzle, can prevent effectively that nozzle from coming off.
A kind of dust collecting for MAP production of the present invention, mainly formed by washing lotion tube, nozzle, snap ring, nuts and bolt, described nozzle screws in the washing lotion tube, nozzle is provided with snap ring, be provided with nut on the snap ring, be provided with nut on the washing lotion tube, by the connection of bolts and nuts, realize being fixedly connected with of washing lotion tube and nozzle.
Described snap ring is made by corrosion resistant plate, its manufacture method is respectively to bore a hole on distance two ends 12.5mm place center line, be bent into respectively the right angle at distance two ends 20～25mm place, again the centre is partly made the annulus of Φ a 45～50mm, two ends is overlapping, two ends can be fixedly connected with the hole of bolt by two ends, again at the circumferential uniform welded nut of annulus.
Dust collecting of the present invention adopts bolt to be fixedly connected with, and connects reliably, has realized the effective collection to dust, to the fine dusts that washing is collected, recoverable behind the airing; Nozzle and washing lotion tube have been realized effective link among the present invention, can increase washing face, and the rate of recovery that reclaims the fine dusts of tail gas increases environmental contamination reduction.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1-washing lotion tube, 2-snap ring, 3-nut, 4-bolt, 5-nut, 6-nozzle.
The specific embodiment
In order to deepen the understanding of the present invention; the present invention is described in further detail below in conjunction with embodiment; this embodiment only is used for explaining the present invention; do not consist of the restriction to protection domain of the present invention; all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
As shown in Figure 1, a kind of dust collecting for MAP production of the present invention, mainly formed by washing lotion tube 1, nozzle 6, snap ring 2, nut 3, nut 5 and bolt 4, nozzle 6 screws in the washing lotion tube 1, nozzle 6 is provided with snap ring 2, is provided with nut 5 on the snap ring 2, is provided with nut 3 on the washing lotion tube 1, by being connected of bolt 4 and nut 3, nut 5, realize being fixedly connected with of washing lotion tube 1 and nozzle 6.
Described washing lotion tube 1 is the L316 stainless steel tube, and diameter is Φ 50mm.
Described nut 3 specifications are M10, are welded with four along washing lotion tube 1 is circumferentially uniform apart from port of export 30mm place.
Described nozzle 6 circumferential cars have one 3mm dark, the groove that 18mm is wide.
Described snap ring 2 is wide by a 3mm, the long L316 corrosion resistant plate of 207mm is made, its manufacture method is the hole of respectively boring a Φ 10mm on distance two ends 12.5mm place center line, be bent into respectively the right angle at distance two ends 25mm place, again the centre is partly made the annulus of a Φ 50mm, two ends is overlapping, two ends can be fixedly connected with the hole of bolt by two ends, is welded with four nuts 5 annulus is circumferentially uniform again.
Described bolt 4 is four, and length is 120mm.
Nozzle of the present invention is connected firmly, and guarantees poly-fluorine ethylene nozzle never drop-off.
