The abrasion-proof protection device of the semi-dry desulfurization spray gun of the circulating fluidized bed is mounted inside an absorption tower, and is characterized by comprising a port blank flange and an abrasion-proof steel plate, wherein the port blank flange is fixedly connected with a spray gun flange and a spray gun port flange of the absorption tower; the abrasion-proof steel plate is arranged on one face toward a smoke coming direction of the spray gun; and the abrasion-proof steel plate is fixedly connected with the port blank flange. The abrasion-proof protection device of the semi-dry desulfurization spray gun of the circulating fluidized bed provided by the utility model can be used for preventing the spray gun from being worn and impacted by high-speed smoke, so that the service life of the spray gun is prolonged.
Description
Technical field:
The utility model relates to a kind of circulating fluid bed semi-drying method desulfuring spray gun abrasionproof protective device, belongs to circulating fluid bed semi-drying method desulfur technology field.
Background technology:
In the boiler of power plant combustion process, the middle sulfur of fuel can oxidation generate sulfur dioxide, and sulfur dioxide enters in the atmosphere can form acid rain, and abrasionproofs such as environment and health are worked the mischief; Along with the raising of people to environmental requirement, the discharge standard of sulfur dioxide will be more and more stricter.The discharging sulfur in smoke is removed technology also propose higher requirement.
The circulating fluid bed semi-drying method desulfur technology is widely used in medium and small thermoelectric enterprise, but there is following problem in this desulfur technology in the absorption tower: the kind of dust height, venturi section high speed flue gas impacts spray gun, causes the spray gun serious wear.
The utility model content:
At the problem that prior art exists, the purpose of the utility model patent provides circulating fluid bed semi-drying method desulfuring spray gun abrasionproof protective device, makes spray gun avoid the wearing and tearing of high speed flue gas and high dust atmosphere, and anti-wear protective device is easy to change.
The technical scheme that the utility model is taked is:
A kind of circulating fluid bed semi-drying method desulfuring spray gun abrasionproof protective device; be installed in the desulfuration absorbing tower; be provided with spray gun and spray gun interface in desulfuration absorbing tower, it is characterized in that: described abrasionproof protective device comprises the abrasionproof steel plate, and the abrasionproof steel plate is arranged at lance face to the one side of flue gas direction of arrival.
Further arrange and be:
Described abrasionproof steel plate is the V-type steel plate, and the bottom faces of V-type steel plate is to the one side of flue gas direction of arrival.
Described abrasionproof steel plate interface blind flange is connected on the spray gun interface.
Described abrasionproof steel plate is fixedlyed connected with the interface blind flange, and the interface blind flange is connected on the spray gun interface by spray gun flange, spray gun flange, is connected by bolt between interface blind flange and spray gun flange, the spray gun flange.
Described abrasionproof steel plate adopts wear-resisting stainless steel or carbon steel, and the employing welding manner is connected between described abrasionproof steel plate and the interface blind flange.
The beneficial effects of the utility model are as follows:
1, because the setting of abrasionproof steel plate when the ash-laden gas vertical direction up flows from the bottom, from abrasionproof steel plate effluent mistake, protects spray gun not by the wearing and tearing of flow at high speed sweep of gases and high dust atmosphere, is conducive to improve the service life of spray gun.
2, at system's run duration, the abrasionproof protective device can be extracted out from the absorption tower, conveniently carry out installation and maintenance.
3, after working long hours, the breakage of abrasionproof steel plate according to the abrasion condition of abrasionproof steel plate, can select new abrasionproof steel plate to be welded on again on the interface blind flange, is easy to replace.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Fig. 2 for the A of Fig. 1 to view (arrow is depicted as the flue gas direction);
Fig. 3 is the interface blind flange of Fig. 1 embodiment and the welding schematic diagram of abrasionproof steel plate.
Number in the figure: 1 is the interface blind flange, and 2 is the abrasionproof steel plate, and 3 is spray gun, and 4 is the spray gun interface, and 5 is weld part, and 6 is the spray gun flange, and 7 is the spray gun flange, and 10 is desulfuration absorbing tower.
The specific embodiment
As Fig. 1; Fig. 2; shown in Figure 3; in desulfuration absorbing tower 10; be provided with spray gun 3; and spray gun interface 4; a kind of circulating fluid bed semi-drying method desulfuring spray gun of the utility model abrasionproof protective device; be installed in the desulfuration absorbing tower 10; comprise interface blind flange 1; abrasionproof steel plate 2; wherein; abrasionproof steel plate 2 is arranged at spray gun 3 towards the one side of flue gas direction of arrival; abrasionproof steel plate 2 is fixedlyed connected with interface blind flange 1, and interface blind flange 1 is by spray gun flange 6; spray gun flange 7 is connected on the spray gun interface 4, interface blind flange 1 and spray gun flange 6; connect by bolt between the spray gun flange 7.
In the present embodiment; abrasionproof steel plate 2 is the V-type steel plate; the purpose of She Zhiing is like this: when ash-laden gas in the Venturi tube of absorption tower bottom vertically from the bottom up during flow at high speed; contact the bottom of the V-type face of abrasionproof steel plate 2 earlier; and flow through along the steel plate both sides of V-type; thereby the protection spray gun improves the service life of spray gun not by the flow at high speed sweep of gases.
As shown in Figure 3, adopt welding manner to be connected between abrasionproof steel plate 2 and the interface blind flange 1.The material of abrasionproof steel plate 2 is not particularly limited, and adopts wear-resisting stainless steel or carbon steel etc. all can obtain the excellent protection effect.
Abrasionproof protective device of the present invention is conveniently replaced: can the abrasionproof protective device be extracted out from the absorption tower at system's run duration, according to the abrasion condition of abrasionproof steel plate 2, it be changed.
Substitute mode is as follows: after the wearing and tearing of abrasionproof steel plate; the bolt of connecting interface blind flange 1, spray gun flange 6, spray gun flange 7 can be unloaded; because desulfuration absorbing tower is the negative pressure operation; flue gas in the absorption tower can not leak in the environment; after opening flange the abrasionproof protective device is extracted from absorption tower spray gun interface 4; after changing the steel plate worn and torn, again with the abrasionproof protective device from the spray gun interface is packed the absorption tower into, the mounting flange of bolting on gets final product.
