Description
The utility model relates to a kind of deduster, particularly a kind of vertical high-voltage electrostatic dust separator.
In the prior art, be used for the vertical high-voltage electrostatic dust separator of dry method, belong to high-efficiency dust remover and so on, dust removing effects uses also more general.But it is also strict to the requirement of dusty gas, processed dusty gas must normal temperature, often could normal operation under the wet stable working condition, service condition is restricted.When the dusty gas temperature that enters high-voltage electrostatic dust separator, humidity, dust concentration variation, dust removing effects significantly descends, when especially humidity changes, (consult figure in addition) because of the insulator in the deduster upper chamber and processed gas are in the equivalent environment, and be connected with high-tension electricity, if processed dusty gas is high humidity, the dust content height, dust just sticks on the insulator, and the creepage short circuit of the easiest puncture causes the electric field decompression that dedusting was lost efficacy.In addition because the variation of temperature, humidity and dust concentration, be adsorbed on dust on the deduster inwall by electric field, though the vibrator rapping is arranged,, also be difficult to come off because of humidity is bigger, influence dust removing effects equally, efficiency of dust collection is descended.
The purpose of this utility model be disclose a kind of in handling the dusty gas process, the vertical high-voltage electrostatic dust separator that not influenced by temperature, humidity, dust concentration.
The utility model is realized by following proposal.
It comprises the casing that constitutes the electrostatic duster with water membrane and stabilized pressure bottom, the dusty gas of casing bottom enters pipe, be connected the lead that constitutes the high-pressure electrostatic loop on the casing, high voltage electrostatic equipment, be connected insulator and lead on the negative high voltage circuit, communicate with casing and perpendicular to the electric field cylindrical shell of the absorption dust of the conduct positive pole on the casing, vertical lifting is at the corona wire that is connected with the negative high voltage circuit of electric field cylindrical shell center, be characterized in: the upper orifice that the dusty gas of casing lower end enters pipe has one section to stretch in the casing, the equal blast cap that the top of upper orifice has support bar to prop, all on the blast cap water pipe that has shower nozzle is arranged, the dusty gas air inlet pipe stretches into a section of casing and constitutes tank at bottom half with casing, and casing bottom one side has the slime water discharge pipe that communicates with casing.It is the tank that bell-mouthed inner core constitutes that suitable for reading section of electric field cylindrical shell has the urceolus that is drawn in by the end mouth that is enclosed within and is welded on the cylinder body outer wall and the electric field cylindrical shell of packing into the end mouth in suitable for reading, the urceolus of formation Storage water tank and the upper port of inner core are higher than the upper port of electric field cylindrical shell, water between the horn mouth periphery of inner core bottom and the inwall of electric field cylindrical shell in the formation tank flows downward along the electric field cylinder inboard wall and forms the slit of moisture film, and the horn mouth periphery of inner core bottom adopts spot welding to be connected with the electric field cylindrical shell.On the electric field cylinder body outer wall that constitutes under the tank urceolus, be welded with the cross-arm that the brace type insulator is installed.The top design suitable for reading of electric field cylindrical shell has the rainhat that is supported by brace type insulator 11, and the corona wire mast-up is arranged in the rainhat, and termination, the outside section of corona wire mast-up is welded on the upper end of brace type insulator, and rainhat is supported.
Electrostatic duster with water membrane and stabilized pressure described in the utility model, the casing that dusty gas enters the lower end is distributed in the whole box body through equal wind, at first capture by the vaporific water dust that particle is bigger of shower nozzle ejection, entering electric field cylindrical shell, dust then moves to the electric field cylinder inboard wall under the effect of high voltage electric field, pooling together the bottom half and the shower water that flow to the lower end with the moisture film that flows downward from the upper end tank along inwall converges, discharged by the slime water discharge pipe, the inwall of electric field cylindrical shell does not adhere to dust.Because the brace type insulator that is connected with high-voltage conducting wires is in the air outside the electric field, be not subjected to the influence of gas temperature, humidity, dust concentration in the electric field, do not puncture, the fault of creepage, short circuit, can remain stable high voltage, keep stable highfield.Dusty gas can not only be lowered the temperature gas after spray gives processing, and humidification can also make too high dust ratio lower, and its dust content of gas of discharging from the electric field cylindrical shell is at 100mg/m
3Following high standard discharging.When the treating capacity of dusty gas is 2000m
3During/h, the electric field cylindrical shell adopts the monotubular structure, when the dusty gas treating capacity at 2500m
3The electric field cylindrical shell adopts many barrel structures during/h, no matter be monotubular or many barrel structures, all is lifted with a corona wire in each electric field cylindrical shell.
