The utility model content:
The purpose of this utility model is to provide a kind of fume desulfurizing tower that can change nozzle outside tower, it carries out the dismounting of spray thrower and the nozzle platform by operating personnel appropriate location outside being arranged at tower, avoided desulfurizing tower to need program out of service, that replace, clean, also avoided the workman enter tower ascend a height exist suffocate, poisoning, the security risk of falling.
in order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises tower body 1, gas approach 2, demister 3, exhanst gas outlet 4, spray thrower installing hole 5, spray thrower 6, tube connector 7, header 8, the middle part of tower body 1 is provided with gas approach 2, tower body 1 upper inside is provided with several demisters 3, the top of tower body 1 is provided with exhanst gas outlet 4, be provided with several layers of spray thrower installing hole 5 on the outer wall of tower body 1, and every layer has several installing holes, spray thrower 6 is arranged on spray thrower installing hole 5 by blind flange 63, the jet pipe 62 of spray thrower 6 is connected with tube connector 7, nozzle 61 is installed on jet pipe 62, and nozzle 61 is arranged on an end of tower body 1 inside, tube connector 7 is connected with header 8.
The cross sectional shape of described tower body 1 is circle or square or rectangle or other shape.
The bottom of described tower body 1 is provided with the circulating absorption solution of certain liquid level.
Operation principle of the present utility model is: flue gas enters desulfurizing tower tower body 1 and upwards flows from the gas approach 2 that is positioned at tower body 1 middle part, removed sulfur dioxide by the absorption liquid that sprays from top nozzle 61, through after being installed on tower body 1 and removing mist near the demister 3 at top, discharge desulfurizing towers by the exhanst gas outlet 4 of tower top again.
The utility model carries out the dismounting of spray thrower and the nozzle platform by operating personnel appropriate location outside being arranged at tower, avoided desulfurizing tower to need program out of service, that replace, clean, also avoided the workman enter tower ascend a height exist suffocate, poisoning, the security risk of falling.Generally all lower than 1000Pa, as long as take certain measure, can accomplish the replacing nozzle of not stopping running due to the operation internal pressure of desulfurizing tower.
Description of drawings:
Fig. 1 is structural representation of the present utility model,
Fig. 2 be the A-A of Fig. 1 to cutaway view,
Fig. 3 is the B section enlarged drawing of Fig. 1.
The specific embodiment:
referring to Fig. 1-Fig. 3, this specific embodiment adopts following technical scheme: it comprises tower body 1, gas approach 2, demister 3, exhanst gas outlet 4, spray thrower installing hole 5, spray thrower 6, tube connector 7, header 8, the middle part of tower body 1 is provided with gas approach 2, tower body 1 upper inside is provided with several demisters 3, the top of tower body 1 is provided with exhanst gas outlet 4, be provided with several layers of spray thrower installing hole 5 on the outer wall of tower body 1, and every layer has several installing holes, spray thrower 6 is arranged on spray thrower installing hole 5 by blind flange 63, the jet pipe 62 of spray thrower 6 is connected with tube connector 7, nozzle 61 is installed on jet pipe 62, and nozzle 61 is arranged on an end of tower body 1 inside, tube connector 7 is connected with header 8.
The cross sectional shape of described tower body 1 is circle or square or rectangle or other shape.
The bottom of described tower body 1 is provided with the circulating absorption solution of certain liquid level.
