Detailed Description
The invention is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.
As shown in fig. 1 to5, the present invention provides an exhaust gas purifying apparatus for a steam turbine system, which can remove oil particles contained in the exhaust gas of the steam turbine, purify exhaust gas, exchange heat with desalted water by using exhaust steam discharged from a steam turbine, and improve the utilization rate of heat energy. Specific:
the tail gas optimizing device comprises a turbine body 1, a desalting water tank 2 and a tail gas treatment and utilization device 3.
The turbine body 1 is a core component of a steam turbine and is used for converting heat energy into mechanical energy and discharging exhaust steam in the energy conversion process. Specific:
The steam turbine body 1 is provided with a water supplementing port 101 and a dead steam outlet 102, and an oxygen removing device (not shown in the figure) is further arranged in the steam turbine body 1. The water compensating port 101 is used to add a large amount of demineralized water to maintain balance of the boiler water supply amount.
Wherein, the desalination water tank 2 is used for providing desalination water for the turbine body 1. The desalination water tank 2 is connected with the water supply port 101 through a water supply pipe 201. Specifically, the water inlet end 202 of the water supply pipe 201 is connected to the desalination water tank 2, and the water outlet end 203 of the water supply pipe 201 is connected to the water supply port 101.
Wherein, tail gas treatment utilizes device 3 to be used for getting rid of the greasy dirt that contains in the exhaust steam to preheat the demineralized water that adds. Specific:
the tail gas treatment and utilization device 3 comprises an oil removing inner sleeve 301 and a heat exchange outer sleeve 302, two ends of the oil removing inner sleeve 301 are respectively provided with an air inlet end 303 and an air outlet end 304, the air inlet end 303 is connected with the exhaust steam outlet 102, a centrifugal oil separator 305 is arranged on one side, close to the air inlet end 303, of the oil removing inner sleeve 301, an oil outlet 306 is arranged on one side, close to the air outlet end 304, of the oil removing inner sleeve 301, the oil outlet 306 is connected to an external oil storage barrel 308 through an oil pipe 307, the air outlet end 304 is further provided with a flow guiding assembly 309, a plurality of partition plates 310 are annularly arranged in the heat exchange outer sleeve 302, the partition plates 310 divide the interior of the heat exchange outer sleeve 302 into a plurality of heat exchange cavities 311, the flow guiding assembly 309 guides exhaust steam in the oil removing inner sleeve 301 into the plurality of heat exchange cavities 311, and the water supply pipe 201 is inserted into the plurality of heat exchange cavities 311 in a reciprocating mode.
The oil removing inner sleeve 301 comprises a conical expansion section 312 and an inverse conical gathering section 313, the centrifugal oil separator 305 is mounted at the small-caliber end of the conical expansion section 312, and the air outlet end 304 is arranged at the small-caliber end of the inverse conical gathering section 313.
Through the centrifugal oil separator 305, the exhaust steam is divided into two parts, and the oil stain is thrown on the wall of the oil removing inner sleeve 301. The provision of tapered expansion section 312 prevents oil contamination from being carried directly to air outlet end 304 by higher air pressure. This is because the gas pressure gradually decreases as the caliber of the tapered expansion section 312 increases, thereby enhancing the oil-gas separation effect.
The inverted cone-shaped gathering section 313 is beneficial to gathering the oil stains on the wall of the oil removing inner sleeve 301 at the air outlet end 304, so that the collection efficiency of the oil stains is accelerated.
The air outlet end 304 is provided with a conical drainage ring 314 extending to the inside of the reverse conical gathering section 313, the large-caliber end of the conical drainage ring 314 is close to one side of the air outlet end 304, and the oil outlet 306 is arranged between the reverse conical gathering section 313 and the conical drainage ring 314 and is close to one side of the air outlet end 304.
The conical drainage ring 31 further enhances the separation of the oil stains, so that the oil stains are gathered in the space enclosed by the inverted conical gathering section 313 and the side wall of the conical drainage ring 314 at the air outlet end 304, and the oil stain particles can be prevented from being directly reserved from the air outlet end 304.
The cross-section of the small diameter end of the tapered drainage ring 314 is larger than the cross-section of the inlet end 303. Thereby ensuring that the exhaust steam from which the greasy dirt is separated can flow out from the air outlet end 304 under the drainage effect of the conical drainage ring 314.
The oil pipe 307 is provided with an oil valve (not shown). When the oil storage barrel 308 is full of oil stain, the oil valve can be closed, and the oil storage barrel 308 can be replaced to continue oil storage.
The flow guiding assembly 309 includes an air outlet cylinder 315 connected to the air outlet end 304, a plurality of air outlet holes 316 extending from the inside of the air outlet cylinder 315 to the plurality of heat exchange cavities 311 are annularly arranged on the sidewall of the air outlet cylinder 315, and unidirectional air inlet valves (not shown) are disposed on the air outlet holes 316. The one-way air inlet valve can ensure that the air exhausted from the air exhaust hole 316 does not flow back, and the reverse resistance to the exhaust steam in the flowing process is avoided.
The ring mouth of the conical drainage ring 314 is provided with a polytetrafluoroethylene hydrophobic membrane 317. In order to further prevent oil stains from entering the air outlet cylinder 315 from the end part of the conical drainage ring 314, the polytetrafluoroethylene hydrophobic membrane 317 is arranged, so that the conical drainage ring 314 can effectively block the oil stains from passing through while ventilation, and long-term work is avoided, and the side wall of the flow guide assembly 309 is blocked by the oil stains. The polytetrafluoroethylene hydrophobic membrane 317 may be periodically replaced.
And, several heat exchange cavities 311 are connected by a multi-way exhaust pipe 318. Under the action of the gas pressure, the heat exchange gas in the heat exchange cavity 311 is collected and discharged from the multi-way exhaust pipe 318.
The working principle of the device is as follows:
The exhaust steam discharged after the steam turbine body 1 works is firstly separated by the centrifugal oil separator 305 of the oil removing inner sleeve 301, oil stains are centrifuged to the wall of the oil removing inner sleeve 301, and flow to the oil outlet 306 between the inverted cone gathering section 313 and the cone drainage ring 314 along the inner walls of the cone expansion section 312 and the inverted cone gathering section 313, and finally flow to the oil storage barrel 308 along the oil pipe 307, so that the influence of oil stain particles in the exhaust steam of the steam turbine on the environment is reduced, and favorable conditions are created for further recycling of the exhaust steam; a small amount of oil dirt remained in the exhaust steam flowing out of the shape drainage ring 314 can be absorbed again by the polytetrafluoroethylene hydrophobic membrane 317 arranged at the ring opening of the conical drainage ring 314;
The exhaust steam after removing the greasy dirt passes through the shape drainage ring 314 of the air outlet end 304 and flows out from each exhaust hole 316 of the air outlet cylinder 315 into the corresponding heat exchange cavity 311, and as the part of exhaust steam has no greasy dirt, the erosion to the inner wall of the heat exchange outer sleeve 302 can be reduced, and the service life of the device is prolonged. The low-temperature exhaust steam formed after the exhaust steam exchanges heat with the desalted water in the water supply pipe 201 flows out through the multi-way exhaust pipe 318, and the exhaust steam can be directly discharged because of no greasy dirt, and the residual heat in the exhaust steam can be further utilized, for example, the exhaust steam is used for heating domestic water;
The inner cavity of the heat exchange outer sleeve 302 is divided into a plurality of chambers by the partition plate 310, and the water supply pipe 201 is inserted into each heat exchange chamber 311 in a reciprocating way, so that the desalted water in the water supply pipe 201 can be subjected to multiple heat exchange, and the heat exchange efficiency is improved;
The preheated desalted water in the water supply pipe 201 is sprayed from the water supplementing port 101 of the steam turbine body 1 and deoxidized by the deoxidizing device, so that on one hand, pollution of pollutants contained in the exhaust steam to the desalted water can be avoided, and on the other hand, the exhaust steam heat is effectively utilized to preheat the desalted water. Compared with the method for directly deoxidizing the desalted water by using the exhaust steam, the device provided by the invention has the advantages that the exhaust steam waste heat utilization function is reserved, meanwhile, the oil removal emission of the exhaust steam is realized, the heating and deoxidization of the desalted water are separately carried out, the purity of the desalted water and the condensed water is maintained, and the service life of the device is prolonged.
While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
