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 and filter efficiency is relatively low.
Air induction conduit of the present invention specifically refers to the structure for introducing gas in closed shell; 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: gas is entered into inside filter element by air induction conduit, owing to the filter element other end is set to blind end, gas can only pass through the calcium oxide arranged in sandwich and enter into outside 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 gas that the gas outside filter element is cleaning, clean gas is discharged by outlet passageway, owing to the inner space of filter element is much smaller than the inner space of closed shell, entered into the gas within closed shell by filter element can spread rapidly and discharge, make the internal pressure much larger than closed shell of the pressure within filter element, namely the inside and outside side pressure difference of filter element is bigger, improve the filter effect of filter element, so, instant invention overcomes existing filter apparatus configuration loaded down with trivial details, the problem that filter efficiency is relatively low.
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, realize the filtration to combustion gas, combustion gas after filtration was discharged by the beginning of filter element, and present configuration is simple; And the present invention adopts is by the internal filter type to outside of filter element, filter element intrinsic pressure much larger than external pressure, it is possible to effectively improved efficiency.
Further, the outlet side of closed shell is provided with the fixing seat of filter element, and the blind end of filter element is connected with the fixing seat of filter element.
Improve the structural stability of filter element, it is to avoid the problem that filter element in use rocks.
Further, the fixing seat of filter element is connected by dividing plate with closed shell.
Further, outlet passageway, at least provided with 2, is separated by dividing plate between adjacent outlet passageway.
Further, the inwall of filter element is set to wavy shaped configuration.
Wavy shaped configuration can effectively increase filter area, improves filter effect.
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 preferred kapok of described cloth, nylon; The setting of steel wire can strengthen the structural stability of filter element.
Further, it is provided with drainage screen in air induction conduit.
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 air induction conduit is provided with joint I, and the outlet side of enclosed housing is provided with joint II.
Joint I, joint II are for being connected defecator with other associated devices.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by arranging the filter element with sandwich, 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.
What 2, invention adopted is by the internal filter type to outside of filter element, filter element intrinsic pressure much larger than external pressure, it is possible to effectively improved efficiency.
