Description
Technical field
The present invention relates to gas-filtering device field, in particular it relates to a kind of based on the filter mechanism improving combustion gas purity.
Background technology
Based on the indispensable a kind of device of tubing that the filter mechanism improving combustion gas purity is pumped (conveying) medium, it is typically mounted on the inlet end of gas turbine.
Gas turbine inlet air end is filter out dust granule in combustion gas, harmful gas, solid matter etc. based on the filter mechanism Main Function improving combustion gas purity, make the combustion gas entering gas turbine clean, prevent the material such as dust granules in air, steam gel from entering air flue, gas turbine inlet air amount is caused to reduce, thus reducing output and the thermal efficiency of gas turbine generator group, prevention compressor blade is dirty and produces vibrations, increases the power consumption of unit operation.
Existing gas turbine defecator generally all adopts multistage filtering loaded down with trivial details with the use of, multistage filtering not only structure and is not easy to maintenance.
Summary of the invention
The technical problem to be solved is to provide a kind of based on the filter mechanism improving combustion gas purity, to overcome the loaded down with trivial details problem of existing filter apparatus configuration.
This invention address that the problems referred to above be the technical scheme is that based on the filter mechanism improving combustion gas purity, including closed shell, the inlet end of closed shell is provided with inlet channel, the fixing seat of filter element, filter element it is provided with in closed shell, filter element is provided with sandwich, filter element one end is blind end, the other end is the beginning, the outlet side of closed shell is provided with the through hole coordinated with filter element, the blind end of filter element is connected with the fixing seat of filter element, the beginning of filter element, through through hole, is filled with calcium oxide in described sandwich.
The existing defecator for gas turbine inlet air end adopts multistage filtering, and every grade of filtration needs to arrange a filter, causes that the structure of whole filtration system is loaded down with trivial details.
The passage combustion gas that inlet channel of the present invention specifically refers to be formed between bottom the sidewall and inlet end of closed shell is entered in closed shell by inlet channel; Described sandwich specifically refers to the sidewall of filter element and is provided with internal layer and outer layer, internal layer and between be formed with interlayer, calcium oxide is arranged in interlayer;Described calcium oxide is existing material, it is possible to absorb the moisture in popularity and sour gas, moreover it is possible to intercept solid particle.
The work process of the present invention: combustion gas is entered in closed shell by admission line, owing to the other end of closed shell is closed, combustion gas can only pass through the calcium oxide arranged in sandwich and enter into inside filter element, owing to the calcium oxide moisture to being mixed with in combustion gas and sour gas absorb and intercept solid particle, thus enter into the combustion gas that the combustion gas within filter element is cleaning, owing to filter element one end is closed, combustion gas after filtration was discharged by the beginning of filter element, reduce the pressure within filter element, and in closed shell, constantly enter combustion gas, thus the pressure outside filter element is more than inside pressure, in filter element, outside forms pressure reduction, pressure reduction makes the sandwich that combustion gas passes through filter element be filtered processing.
The present invention has the filter element of sandwich by arranging, it is provided with for absorbing the calcium oxide of moisture and sour gas in combustion gas in sandwich, in filter element, outside forms pressure reduction, make combustion gas by penetrating into inside filter element outside filter element, realizing the filtration to combustion gas, the combustion gas after filtration was discharged by the beginning of filter element, and present configuration is simple, so, instant invention overcomes the problem that existing filter apparatus configuration is loaded down with trivial details.
Further, filter element is column construction or the square structure of hollow, and the sidewall of filter element is set to sandwich.
Further, the sidewall of filter element adopts cloth to make.
The preferred kapok of described cloth, nylon.
Further, the sidewall of filter element adopts steel wire to make, and steel wire has been sticked cloth.
The setting of steel wire can strengthen the structural stability of filter element.
Further, inlet channel is at least provided with 2, and adjacent inlet channel is separated by dividing plate.
Further, inlet end place in closed shell inherence is provided with drainage screen.
The large particulate matter of combustion gas inlet side can be carried out intercepting filtration by drainage screen, it is to avoid large particulate matter blocking filter element.
Further, the inlet end of closed shell is provided with joint I, and the beginning of filter element is provided with joint II.
Joint I, joint II are for being connected defecator with other associated devices.
Further, the beginning of filter element is connected to funnel structure, and the interior of funnel structure is gradually increased to outlet side with filter element link without leave, and described joint II is connected with funnel structure.
Arranging of funnel structure can have the exhaust velocity increasing filter element, increases the pressure reduction in outside in filter element further, improves filter efficiency.
To sum up, the invention has the beneficial effects as follows:
The present invention has the filter element of sandwich by arranging, in sandwich, it is arranged to absorb the calcium oxide of moisture and sour gas in combustion gas, in filter element, outside forms pressure reduction, make combustion gas by penetrating into inside filter element outside filter element, realize the filtration to combustion gas, combustion gas after filtration was discharged by the beginning of filter element, and present configuration is simple.
