Abstract
The utility model discloses a filter device, and particularly relates to a Y-shaped filter used for a main fuel transmission pipeline of a heavy duty gas turbine, which comprises an inlet (1), a main body (2), a cover arranged at the bottom of the main body (2), an outlet (4) and a filter screen (5) arranged in the main body (2), wherein the central line of the inlet (1) is coaxial with the central line of the outlet (4), and certain angles are formed between the central line of the main body (2) and the central lines of the inlet (1) and the outlet (4). The utility model is characterized in that the included angles between the central line of the main body (2) and the central lines of the inlet (1) and the outlet (4) are 45-55 degrees, and a pipe wall of the main body (2) is in a convex arc shape. The utility model has the functions that the angles between the central line of the main body and the central lines of the inlet and the outlet are adjusted, and the pipe wall of the main body is arranged in the arc shape to increase circulation area, so that the requirement of equipment on pressure reduction is met, the filter has a wider application range, and the filter screen can not be broken and further enter the equipment to cause equipment paralysis and damage.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of y-type filter that is used for the delivery of main fuel pipeline of heavy duty gas turbine.
Background technology
China readjusts the energy structure energetically the Eleventh Five-Year Plan period, to reduce the environmental pollution that coal-fired unit causes, wherein the heavy duty gas turbine generating has had tremendous development, and gas turbine power generation belongs to clean energy resource, pollutes minimum, the more important thing is the generating efficiency height, can be used as the peak regulation unit and use.
But y-type filter of the prior art, and be not suitable for the delivery of main fuel pipeline of heavy duty gas turbine, because its circulation area is little, and the fuel gas temperature height of the filter of flowing through has very high requirement to the filter screen of filter, if do not reach requirement and the filter screen insufficient strength of equipment to pressure drop, cause filter screen to be broken through easily, damaged filter screen enters steam turbine inside, causes the system shutdown paralysis, has a strong impact on equipment life.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of Y shape filter is provided, and solves prior art can't be applied to main equipment owing to its reason that does not satisfy pressure drop and filter screen insufficient strength problem.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Y shape filter, comprise import, main body, be arranged on bottom part body lid, export and be arranged on the filter screen in the main body, wherein import is coaxial with center line of discharge, the center line of main center's line and import and outlet at an angle, angle between the center line of main center's line and import and outlet be 45 spend to 55 the degree, the tube wall of main body is the circular arc of evagination.Angle is arranged in this scope and the tube wall of main body is arranged to circular arc can effectively increase the circulation area of Y shape filter, thereby satisfy the requirement of equipment pressure drop.
Further technical scheme is:
Angle between the above-mentioned main center's line and the center line of import and outlet is 50 degree.
Above-mentioned filter screen is by comprising that circular reinforcement, some mesh grids and punching net mutual superposition form, and the two ends of filter screen are provided with retainer plate.This filter screen is different from filter screen of the prior art, and the sealing effectiveness at these filter screen two ends is better.
Above-mentioned circular reinforcement, some establishment nets and punching net are fixed together by screw; Above-mentioned filter screen also comprises band steel, and band steel also is fixed on the screw; The filter screen inwall is provided with horizontal reinforcement.By circular reinforcement, band steel and the horizontal better fixing filter screen and increase its intensity of reinforcement.
Above-mentioned mesh grid has five layers at least.The number of plies according to actual conditions adjustment mesh grid needs five layers at least in steam turbine.
Compared with prior art, the beneficial effects of the utility model are: by the angle between the center line of adjusting main center's line and import and outlet and the tube wall of main body is arranged to circular arc increases circulation area, to reach the requirement of equipment to pressure drop, make its scope of application wider, and make filter screen be unlikely to damaged and access arrangement causes the equipment paralysis to damage.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model internal screen structural representation.
Fig. 3 is the vertical view of Fig. 2.
Among the figure: 1 is import, and 2 is main body, and 3 are lid, and 4 are outlet, and 5 is filter screen.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of Y shape filter, comprise import 1, main body 2, be arranged on lid 3, the outlet 4 of main body 2 bottoms and be arranged on filter screen 5 in the main body 2, wherein import 1 is coaxial with outlet 4 center lines, main body 2 center lines and import 1 and export 4 center line at an angle, main body 2 center lines and import 1 and the angle that exports between 4 the center line are 50 degree, and the tube wall of main body 2 is the circular arc of evagination; As Fig. 2, shown in Figure 3, filter screen 5 is by comprising that circular reinforcement, establishment net and punching net mutual superposition form, and be fixed together by screw, filter screen 5 also comprises band steel, band steel also is fixed on the screw, filter screen 5 inwalls are provided with horizontal reinforcement, and the two ends of filter screen 5 are provided with retainer plate, and the establishment net has five layers at least.
This y-type filter design temperature arrives 350 ℃, design pressure 10.0MPa, the structural design of this filter screen, material and the design of whole structure of filter can be satisfied equipment normally operation under high-temperature and high-pressure conditions, ensure the service life of product, and the circulation that has guaranteed and pressure drop (pressure drop of clean net≤0.144bar).
