Description
Technical field
The utility model is related to power plant's water spray dust removal field, more particularly, to a kind of dust removal showerhead.
Background technology
With being gradually increased for China environmental protection dynamics, coal-fired power station boiler has mostly added flue gas desulfurization device.Its
In, wet desulfurization of flue gas by limestone-gypsum method technique is at home and abroad used widely because of its technology maturation, reliability, accounts for desulfurization
90% or so of installed capacity.During lime stone gypsum slurries washing flue gas, the gaseous contaminant and flying dust in flue gas
It is washed to enter in gypsum slurries, wherein the harmful substance such as the chlorion for containing, heavy metal ion also enters into therewith flue gas taking off
In sulphur system, and in gypsum treatment technical process, as flushing water enters desulfurization wastewater link, define rich in heavy metal and
The desulfurization wastewater of chlorion.Desulfurization wastewater has that total amount is few, be difficult to process and is easy to produce secondary pollution problems.
The larger fume wet type desulphurization dedusting inner screw jet nozzle of the coal smoke amount such as power plant, cement plant, because shower nozzle makes
Used in high temperature, corrosivity is strong and erosive wear working environment, thus spray nozzle integrative performance is required higher, such as require shower nozzle heatproof
More than 200-300 DEG C, and weak acid resistant weak base, resistance to solid phase particles high speed erosive wear, and preferably mist formation performance.Inside spin
Shower nozzle, eddy flow degree of spraying water is the key of mist formation quality, and built-in spray piece spray groove and spin chamber are affect water spray eddy flow two
Individual principal element.Existing inner screw jet nozzle, is generally processed into using stainless steel or titanium alloy material, due to processing reason,
Built-in artesian well sprays groove, is only that some inclined holes are drilled with artesian well, and shower nozzle lower house spin chamber adopts square or pyramidal structure,
This oblique hole for water spraying and square or taper eddy flow chamber jet, water spray eddy flow effect is bad, causes to spray mist formation poor performance.Secondly,
Metal material shower nozzle, needs machining one by one, and not only difficulty of processing is big, hardly results in ideal spiral spray groove and spin chamber, and
Performance is not ideal enough, and stainless steel shower nozzle is only alkaline-resisting and not acidproof, the corrosion of flue dust acid mist plus washes away abrasion and easily causes spray orifice to expand；
Although titanium alloy shower nozzle energy acid-fast alkali-proof, wear resistance is less than stainless steel, can equally cause spray orifice to expand again.Stainless steel and titanium
Alloy inner screw jet nozzle, not only high cost, service life is short, and mist formation performance is bad, and the spray orifice that especially weares and teares expands, mist formation
Property it is worse, affect spray desulfurization and dedusting effect.Besides because shower nozzle fogging itself is poor, increase hydraulic pressure can only be taken in application
Cover the shortage, cause to increase using power consumption again.
At present, the cooling system of the steam turbine of water-saving power plant adopts hybrid indirect air convection current refrigerating mode, and this is
Tong Keshiquan factories water consumption reduces more than 60%.It is mainly made up of the air cooling tower of injecting type condensing engine and Fu Ge type radiators,
Cooling water in system directly mixes with exhaust steam in steam turbine into condensing engine and condenses it；Cooling water after being heated is by circulating pump
Air cooling tower radiating is delivered to, injecting type condensing engine is delivered to again Jing after with cross-ventilation heat exchange cooling and is entered subsequent cycle.Its shortcoming
It is：The radiating fin of cooling tower is all exposed to the external world, for air in each pollutant provide implantation, during these attachments
Quarter affects the effect of cold and hot exchange.There is abnormal, reduction vapour in the increasingly severe attachment of accumulation, the operating that steam turbine can be made
The delivery efficiency of turbine, causes increasing for generating power consumption, so as to increased production cost.Unit operation is it was verified that work as convection current
When air-flow reduces by 20%, the rear pressure of turbine increases by 33%, so as to have influence on safe operation and the generating efficiency of equipment.
In sum, there is problems with existing dust removal showerhead：
1st, dust removal showerhead is typically made up of head body and the water proof blade being arranged in head body, in powerful injection
Under pressure, water proof blade easily comes off from head body；
2nd, dust removal showerhead angle of water is less, and spray regime is less, effect on driving birds is not good.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of dust removal showerhead, the water proof body and shower nozzle in the shower nozzle
Body is connected firmly, and the water spray angle of the shower nozzle is big, and scope is wider, and effect is more preferable.
The utility model solve the technical scheme that adopted of above-mentioned technical problem for：A kind of dust removal showerhead, including shower nozzle sheet
Body and water proof body, are provided with injection runner, and the water storage cavity being connected with injection runner, described storage in described head body
Water cavity inwall is provided with convex tendon, and described water proof body is provided with the helicla flute matched with convex tendon, by described helicla flute with it is convex
Muscle cooperates, and described water proof body is connected in water storage cavity, and described injection runner upper end is provided with spout, described spout
Taper is 120 °.
Further improve as the utility model, described water proof body structure in the shape of a spiral, described water proof body is by two panels
Structure identical water-impermeable piece is connected with each other and forms.Two panels water-impermeable piece constitutes spiral helicine water proof body, it is easier to breaks up and breaks up in water,
Further improve water spray effect of the present utility model.
Further improve as the utility model, described head body is similar to as cylindrical-shaped structure, described shower nozzle sheet
External surface is interval with a plurality of cannelure, and on described a plurality of cannelure O-ring seal is equipped with.Setting by O-ring seal
Put, the water injector that the utility model can be made supporting with its is preferably connected, and improves the utility model close with water injector
Feng Xing, strengthens irrigation pressure, and then improves water spray effect of the present utility model.
Compared with prior art, the utility model has the advantage of head body is connected firmly with water proof body, specifically,
Water proof body passes through the helicla flute of outer surface and the convex tendon clamping of water storage cavity wall, even if under powerful injection pressure, water proof body
Also it is not easy to be come off from water storage cavity, in addition, the taper of spout is set to into 120 °, increases spray regime, makes jeting effect
More preferably.
