Abstract
The invention relates to an improved structure of a gas turbine exhaust duct. The improved structure comprises a duct body, a notch is formed in the annular wall of the duct body, the two side walls of the notch are symmetrically provided with two grooves, one end of each groove is arranged to be an opening end, and the other end of each groove is arranged to be a closed end; and the two sides of an arc-shaped plate are provided with protruding edges matched with the grooves, and a tubular structure is formed by the arc-shaped plate and the duct body with the notch. According to the improved structure, the notch is formed in the duct body, the arc-shaped plate which can be freely demounted and mounted is arranged to be matched with the notch, sedimentation particles on the arc-shaped plate are removed at regular intervals, and the problem of particle sedimentation in the duct body due to increase of exhaust stream resistance is solved.
Description
Technical field
The present invention relates to gas turbine supplementary equipment field, particularly, relate to a kind of combustion engine exhaust duct modified node method.
Background technique
Gas turbine is with the gas of continuous-flow for working medium impeller High Rotation Speed, is the internal combustion type dynamic power machine of useful work by the energy conversion of fuel, is a kind of rotary vane type heat engine.Gas turbine, as the high efficiency internal-combustion engine of one, is applied more and more extensive.
Gas turbine can produce a large amount of waste gas in the course of the work, and the waste gas of generation needs to be input in flue gas processing device by conveyance conduit to carry out filtration treatment to waste gas, avoids entering waste gas and is directly drained into befouling environment in air.
In the front end of filtrating equipment, conveyance conduit is set, filtrating equipment is transported on the one hand for what produced by gas turbine, exhaust gas temperature on the other hand due to gas turbine generation is higher, gas pipeline can play heating power buffer function, and the waste gas avoiding temperature too high directly enters into the use that filtrating equipment affects filtrating equipment.
Existing conveyance conduit easily causes the gathering of fallout, increases the resistance of exhaust stream.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of combustion engine exhaust duct modified node method, to overcome the problem that existing gas pipeline easily causes the gathering of fallout in pipeline.
The present invention's adopted technological scheme that solves the problem is: a kind of combustion engine exhaust duct modified node method, comprise body, the ring wall of body is provided with a breach, 2 sidewall symmetry of breach are provided with 2 grooves, groove one end is set to the beginning, the other end is set to end-blocking, and the both sides of arc plate are provided with the chimb with groove fit, arc plate with body jaggy be set form a tubular structure.
Due in the exhaust of gas turbine containing solid particle, solid granular in pipe conveying procedure in pipeline in sedimentation gathering, the resistance of exhaust stream is increased.
Breach of the present invention is the groove that axially arranges at body of vial body ring wall specifically, and described 2 grooves are oppositely arranged, and the end-blocking of groove and beginning specifically refer to that groove is in body 2 ends axially; Described arc plate specifically refers to the connecting plate just surrounding a tubular structure with body.
Working procedure of the present invention: the beginning of arc plate by groove is inserted, coordinating of arc plate and body is realized by coordinating of groove and chimb, during use, body is provided with arc plate side be placed on below, like this conveying waste gas process in solid particles sediment on arc plate, take out arc plate after using a period of time, install again after arc plate is clean.
The present invention, by arranging breach on body, is provided with the arc plate that can freely remove and install and coordinates with breach, regularly arc plate is carried out to the removing of sedimented particle, the problem that the exhaust stream resistance that the sedimentation of body endoparticle causes unavoidably increases.
Further, the end of chimb is provided with tapped hole, and the end of described body is hinged with fixed plate, fixed plate is provided with the tapped through hole coordinated with tapped hole, fixed plate and chimb is fixed with coordinating of tapped hole by bolt.
By arranging fixed plate, further arc plate being fixed on body indentation, there, improving the structure stability of body.
Further, arc plate is provided with handle.
Removing and installing of arc plate is convenient in the setting of handle.
Further, the outer wall of body is provided with thermal insulation layer.
The setting of thermal insulation layer avoids the heat radiation in body to go out, and reduces the thermal radiation of body.
Further, protective layer adopts polythene material to make.
Polythene material is prior art material, has the effect of insulation.
Further, thermal insulation layer is set in tube wall by slide fastener or snap button.
Further, the outer wall of body is set to flank of thread.
Flank of thread effectively can increase the frictional force of body and thermal insulation layer, makes thermal insulation layer firmly be set in tube wall.
To sum up, the invention has the beneficial effects as follows:
The present invention, by arranging breach on body, is provided with the arc plate that can freely remove and install and coordinates with breach, regularly arc plate is carried out to the removing of sedimented particle, the problem that the exhaust stream resistance that the sedimentation of body endoparticle causes unavoidably increases.
