Abstract
A gas turbine inlet air pre-filtering device relates to the technology of gas turbine inlet air pre-filtration and overcomes the weaknesses existing in other technologies, which has the structural relation that an air pre-filtering device is fixed on a support, an upper rolling component and a lower rolling component are respectively arranged at the top end and the lower portion of the air pre-filtering device, the upper rolling component is equipped with filter cloth, grating is fixed in the middle of the air pre-filtering device, second-grade filter elements and first-grade elements are disposed in the air pre-filtering device, wherein the second-grade filter elements present square chest form and the first-grade filter elements are cylindrical, an access door for replacing the first-grade filter elements and an access door for replacing the second-grade filter elements are arranged on the lateral sides of the air pre-filtering device, and an air inlet pipe is arranged at the bottom of the air pre-filtering device. The gas turbine inlet air pre-filtering device has the advantages that the dust containing capacity of the filter cloth is utilized effectively, and the economic benefits of enterprises are increased because filtering wind speed is reduced, the maintenance is convenient because of the access doors, and the filter cloth can be replaced easily and conveniently.
Description
One, technical field:
The present utility model relates to the pre-filtering of cover gas turbine inlet air technology, especially a gas turbine inlet air pre-filtrating equipment.
Two, background technique:
In synthetic ammonia installation, the process air compressor bank is being undertaken the task that process air is provided to secondary reformer, raw material is taken from the air in the atmosphere, behind first and second grade of air filter filter cascade filtration, provide process air to compressor, provide combustion air to gas turbine simultaneously, therefore, the quality of air filter operation conditions plays an important role to the safe and stable operation of gas turbine unit.
The former filter branch of air two-stage: the first order is crossed filter core by 192 cylinder types and is formed, and model is: CY2812, carry out coarse filtration to air; The second level is crossed filter core by 64 square chest types and is formed, and model is: VE1715-760-F, air is carried out the essence filter, and reach the purpose that purifies air, the pressure that two-stage filter allows is reduced to 12mbar, i.e. 124mm water column, design air flow 252000Kg/H.
Though one, the filter precision of two double-filtration cores can meet the demands, but, this device is located in the territory, areas formerly flooded by the Huanghe River, spring, autumns two monsoon sand are bigger, add and adjoin coal fired boiler, solid content is more in the air, and it is foggy to add winter, humidity of the air is big, and the through-current capability of first order filter core is reduced greatly.It is very fast that it rises first and second grade filter pressure reduction, and the replacing frequency of filter core is higher.According to statistics, annual first order filter core is on average changed about 4～5 times, and second level filter core is on average changed about 2～3 times, and therefore etesian filter core ordering cost is about 700,000 yuan.Simultaneously, in the online replacing first order filter core process, air directly contacts second level filter core, influences its working life; During online replacing second level filter core, because of negative pressure is bigger, mechanical admixture can directly enter downstream line, and equipment is caused many adverse effects, and during online more renew cartridge, operating personnel's operating conditions is abominable, and labor intensity is bigger.
Therefore, added a prefilter in the front of original first and second grade two-stage filter and connected, come the larger particles dust in the atmosphere is filtered, to alleviate the pressure of I and II filter.
Three, summary of the invention:
That the purpose of this utility model provides is easy, the gas turbine inlet air pre-filtrating equipment of easy row, it has overcome the shortcoming that other technology exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by last batching assembly, secondary filter core, grid, following batching assembly, air inlet pipe, support, filter cloth, one-level filter core, replacing one-level filter core access door, replacing secondary filter core access door, on support, fixing air pre cleaner, batching assembly, following batching assembly are being installed respectively in the top and the bottom of air pre cleaner; On the last batching assembly filter cloth is arranged; The center fixed of air pre cleaner grid; Secondary filter core and one-level filter core are arranged in air pre cleaner; The secondary filter core is a square chest type, and the one-level filter core is cylindrical; The one-level of replacing filter core access door is arranged in the side of air pre cleaner, change secondary filter core access door; Air pre cleaner the bottom air inlet duct is arranged.
The utility model prefilter filter cloth adopts rolling curtain type to install, it comprises each 2 of the upper and lower batching assemblies of shaking type, filter cloth is fixed on the batching assembly, when filter cloth is installed, tear the bottom of filter cloth with hand, be fixed on down after shutting down on the batching assembly, filter is after operation a period of time, filter cloth is stopped up by dust, when reaching the end of a period resistance, filter pressure reduction (can measure the filter cloth filtration resistance) by differential manometer, can hand lower component, filter cloth in the top batching assembly of leaving behind, and the filter cloth that will change all is involved in lower component.The every volume of filter cloth is 10m, and replaceable 5 times an of filter cloth of volume after changing 5 times, in the time of need renewing a volume filter cloth, can be fixed on top with new filter cloth, links to each other on it is pulled end and an old volume filter cloth, then can proceed to change filter cloth next time.And have access door in the side, in order to changing former two-stage filter core.Easy, the easy row of this method.
The utlity model has following good effect: 1, adopt pre-filtration system to keep off outside as mosquito, leaf, cotton-wool etc. effectively with large granular impurity, the dust capaciting ability of filter cloth is utilized effectively.2, filtration velocity reduces, and the existence of filter cloth and one-level filter core settlement space in addition can avoid humid air directly to suck the one-level filter core effectively, make the filter paper damage of making moist, prolong its working life greatly, reduced filter core and changed frequency, improved economic benefit of enterprises.3, be provided with access door, easy to maintenance; Simultaneously, this prefilter makes this total pressure head of three grades be lower than the pressure reduction of former secondary filter, has reduced the dust suction amount in the unit time, improves unit operation efficient.4, filter cloth adopts rolling curtain type to install, and is provided with upper and lower batching assembly, and it is simple, convenient that filter cloth is changed.
