Description
Technical field
The utility model relates to a kind of wet desulphurization equipment, is specifically related to a kind of anti-gypsum rain device that is used for wet desulphurization equipment chimney top.
Background technology
Along with people's improves constantly and the adjustment of the relevant environmental protection policy of country environmental requirement, the at present wet desulphurization devices that adopt of boiler desulfurization more, and using with wet desulphurization device widely at present is lime/lime stone---the desulfurization of gypsum method.But in the wet desulfurization system, the exhaust temperature of clean flue gas reaches 46 ℃-52 ℃, and the corrosivity of flue gas is bigger in this temperature range.The material of chimney and flue is a concrete, and corrosion resistance is relatively poor.One of existing processing method is anticorrosion for the inside of original concrete chimney and flue is carried out, all boilers of must stopping transport, and the anticorrosion cycle is long, cost is high.Part enterprise considers that at the desulfurizing tower top in line steel stack being set solves the problems referred to above; But this method cost is far above concrete chimney; And the mechanical strength of steel stack and rigidity have determined it highly generally to be no more than 75 meters, far below the height (120 meters～150 meters) of former concrete chimney.The gravelstone cream drop that clean flue gas is carried secretly forms the landing of gypsum rain, and the environment of periphery is caused very big influence, threatens operating personnel's job safety.Therefore, be necessary to design the anti-gypsum rain device that a kind of cooperation is used for wet desulphurization equipment chimney top.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, provides a kind of simple for structure, easy to maintenance and effectively reduce the anti-gypsum rain device that gypsum rain phenomenon is used for wet desulphurization equipment chimney top.
For realizing above-mentioned purpose; The technical scheme of the utility model is a kind of anti-gypsum rain device that is used for wet desulphurization equipment chimney top of design; Said anti-gypsum rain device comprises overhead guard, and the lower end of said overhead guard is provided with several supports that is connected with the chimney body top, is provided with the gas baffle of tubular around the upper end of said chimney body and the overhead guard; Be provided with collecting tank between the lower end of said gas baffle and the outer surface of said chimney body; The lateral wall of said collecting tank is a gas baffle, and the madial wall of said collecting tank and the outer surface of said chimney body are fitted, and the bottom surface low side of said collecting tank is provided with liquid outlet; Said liquid outlet is connected with the slurries return pipe, and said slurries return pipe is used to be communicated with said collecting tank and desulfurizing tower.
, and reduce rainwater and fall into chimney in the circulation of the eddy current at top cover place for the ease of flue gas, slow down the corrosion of gypsum rain to inner wall of stack, optimized technical scheme does, overhead guard is taper, and the openend of said overhead guard is provided with several supports that is connected with the chimney top.
In order further to improve the probability of flue gas and baffle plate secondary collision, optimized technical scheme does, said gas baffle is cylindric, and the end face radius of circle of said gas baffle is less than the bottom surface radius of circle of said gas baffle.
In order to simplify the gas baffle structure, to be convenient to manufacture, optimized technical scheme does, and said gas baffle comprises the side board of column tubular, and said side shield top is provided with to the top of the interior tilt of said side shield baffle ring plate.
In order to prevent the head-on collision of upper-level winds flue gas in to the gas baffle chimney, influence the discharging of flue gas, optimized technical scheme is that the height of said gas baffle is less than the height of said overhead guard.
Stable for overhead guard is connected with gas baffle, make things convenient for the dismounting and the replacing of overhead guard and gas baffle simultaneously, optimized technical scheme is to be provided with connecting rod between said support and the said gas baffle.
The gypsum fluid power flows back in the desulfurizing tower as early as possible in the collecting tank in order to make, and avoids the gypsum corrosion sump bottom gathered, and optimized technical scheme is that the bottom surface of said collecting tank is a V-arrangement.
The advantage and the beneficial effect of the utility model are: this anti-gypsum rain apparatus structure is succinct, convenient for installation and maintenance, and later maintenance cost is low, can directly be used for the transformation of existing desulfurization flue gas chimney; This device can effectively reduce gypsum rain phenomenon, helps to reduce the pollution of wet desulphurization device to surrounding environment, ensures operating personnel's job safety.
