Description
Technical field
The utility model relates to a kind of plug type shower for wet method fume desulfurizing system, is mainly used in small hydropower station boiler, Industrial Boiler and furnace flue gas desulphurization system, belongs to the environmental protection equipment technical field.
Background technology
At present, the removal of pollutants such as SO2 in small hydropower station boiler, Industrial Boiler and furnace flue gas adopt wet method more than 85%, desulfurizing agent adopts lime, lime stone, magnesia, ammoniacal liquor or liquefied ammonia etc., no matter adopt which kind of desulfurizing agent, the absorption tower is all the nucleus equipment in desulphurization system, spray equipment is in the absorption tower, doctor solution to be sprayed to make it the device that fully contacts, mix with flue gas, is one of core apparatus in the absorption tower, and shower is the important component part in spray equipment.Shower generally is arranged on the middle and upper part on absorption tower, and flue gas is entered by the middle and lower part of desulfurizing tower.Its operation principle is by shower and the nozzle that is mounted thereon, the absorbent mean allocation of liquid phase to be formed tiny particle to each position and the atomizing in cross section, absorption tower, contact with vapor phase contaminants in upstream flue gas again and carry out chemical reaction, absorb the sulfide in flue gas, reach and absorb the pernicious gas purpose.Its working environment has the advantages that corrosivity is strong, abrasiveness is strong, and under accident condition, it also needs to bear high temperature.Simultaneously, current shower mostly is fixed installation, and is in case the spray nozzle clogging or the wearing and tearing that are installed on shower need to can only be cut off even blowing out of desulphurization system during urgent replacing, very inconvenient.
The utility model content
The purpose of this utility model is to propose a kind of plug type shower for wet method fume desulfurizing system, change the structure of shower in existing desulfurizing tower, adopt the plug type structure, make and to overhaul, to change the nozzle on shower under the running status of absorption tower, and make it have good corrosion resistance, wearability, heat-resisting quantity and enough strong hardness, to satisfy desulphurization system requirement in service life.
The plug type shower that is used for wet method fume desulfurizing system that the utility model proposes comprises shower pipe box, shower and atomizer; Described shower pipe box is relative with the desulfurizing tower tower body fixing, described shower stretches in the desulfurizing tower tower body by the shower pipe box, described atomizer is connected with shower in stretching into the desulfurizing tower tower body by nozzle connecting pipe, and being in of shower is connected with circulating pump by lap joint flange after the outer end of desulfurizing tower tower body stretches out the shower pipe box.
The plug type shower that is used for wet method fume desulfurizing system that the utility model proposes, its advantage is:
1, the plug-in shower that the utility model proposes is compared with existing structure, need not to arrange support and brace summer, so cost is low, easy for installation, can be in the situation that absorption tower operation maintenance or replacing.
2, the plug-in shower that the utility model proposes adopts improved glass steel (FRP) to make, and structural pipe wall is by interior anticorrosion antiwear layer, impervious barrier, structure sheaf, outer anticorrosion antiwear layer form from the inside to surface.Interior its thickness of wear-and corrosion-resistant layer is 2 millimeters, and adopting epoxy vingl ester resin to add a certain proportion of carborundum is that base material uses the chemical glass fiber to become with the alkali-free glass felt, and its resin content is more than 90%.Antiseepage is that 1.5 millimeters employing epoxy vingl ester resins are that base material uses the alkali-free glass felt to become, and its resin content is more than 75%.It is that the base material alkali-free glass fiber cloth becomes with the alkali-free glass fibre felt that structure sheaf adopts structural resin, its resin content 45% left and right, and thickness calculates by infrastructure software to be decided.Adding a certain proportion of carborundum with epoxy vingl ester resin is that base material uses the alkali-free glass felt to become, and its resin content is more than 75%, and brushing one deck adds the resin of anti-ultraviolet agent at last.The improved glass Steel material satisfies corrosion-resistant, wear-resisting, resistant to elevated temperatures performance, can satisfy enough strong hardness again, more stable operation under can be in the absorption tower complicated work condition environment, and its bulk life time is more than 15 years, and is all longer shelf life than the shower of any material.
3, plug-in shower of the present utility model, to be connected short tube be all one-body molded for reducer, straight section and nozzle on the overall steel mould, inner wall smooth, corner's rounding off fluid resistance is little, weares and teares little, long service life.
