The utility model discloses condensate pump inlet pressure has been reduced, and then the electric energy that the condensate pump consumed has been reduced.
Description
Technical Field
The utility model belongs to the technical field of thermal power factory is energy-conserving, especially, relate to a novel condenser filter screen.
Background
The condensing equipment is an important component of the condensing turbine, and the working condition of the condensing turbine directly influences the economy and the operation reliability of the whole unit. The condensing equipment plays a cold source role in the whole thermodynamic cycle, and utilizes the cooling function of circulating water to establish lower back pressure at the steam exhaust part of the steam turbine so as to ensure that steam works to the maximum extent, then the steam is cooled into condensed water which is recycled to the hot well and is sent back to the system for recycling through the condensed water pump.
The condensate pump is generally a vertical barrel bag type multistage centrifugal pump, and a stainless steel filter screen is arranged at the inlet of the condensate pump and used for preventing dirt of a condenser from entering a system. The condensate pump inlet screen is typically equipped with a differential pressure switch for monitoring the degree of screen blockage to protect the condensate pump.
Referring to fig. 1, the conventional unit adopts a scheme that a filter screen is arranged at an inlet of a condensate pump, so that the pressure at the inlet of the condensate pump is higher, and the electric energy consumed by the condensate pump is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel condenser filter screen to reduce condensing steam type turbo generator set energy consumption.
The utility model provides a novel condenser filter screen, condenser tube bank below hot well department, multichannel are located to the filter screen is vertical echelon and arranges, the per pass the filter screen all traverses whole condenser bottom.
Furthermore, the two sides and the bottom of the filter screen are fixed on a stainless steel frame of the hot well, and the stainless steel frame is welded at the bottom of the hot well.
Furthermore, the filter screen adopts stainless steel material.
Furthermore, the height of the filter screen is higher than the normal water level of the condenser and lower than the highest water level of the condenser.
Borrow by above-mentioned scheme, through novel condenser filter screen, reduced condensate pump inlet pressure, and then reduced the electric energy of condensate pump consumption.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

FIG. 1 is a layout view of a condenser screen in the prior art;
fig. 2 is the utility model relates to a novel structural schematic of condenser filter screen.
Reference numbers in the figures:
1-a condenser tube bundle zone; 2-an air pumping area; 3, filtering by using a filter screen; 4-a hot well; 5-a condensate pump.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 2, the condenser cooling tubes are arranged in a band shape in the condenser tube bundle region 1, and a steam flow channel is left around the condenser cooling tubes to enable steam flow to enter the tube bundle, and steam flow resistance can be reduced.
The air pumping area 2 is positioned at the center of the condenser tube bundle area 1 and separated from the main condensation area by a baffle. The uncondensed gas and the steam can be condensed in a large amount when passing through the air cooling zone, and the rest small part of the steam enters the air pipe along with the uncondensed gas. The steam discharged by the low-pressure cylinder enters the condenser and then is rapidly distributed on the whole cooling water pipe, and the steam comprehensively carries out heat exchange along the surface of the cooling pipe through the channels between the pipe bundles and the channels on the two sides and is condensed into water. The residual non-condensed steam and cooled air are collected in the air pumping pipe of the air cooling area and exhausted by the vacuum pump.
The hotwell 4 is an upright cylindrical part installed at the bottom of the condenser to collect the main condensate water generated by continuous condensation of a large amount of exhaust steam.
The condensate pump 5 is a power device for feeding condensate into the regenerative system.
The filter screen 3 in this embodiment is located condenser tube bank below hot-well 4 departments, and every way filter screen 3 all traverses whole condenser hot-well bottom, and filter screen 3 adopts stainless steel material, and the screw fixation is used to filter screen 3 both sides and bottom on the stainless steel frame of condenser hot-well 4. The steelframe welding is used for fixed filter screen 3 in condenser hot well bottom, and multichannel filter screen is vertical echelon and arranges. According to different units, the filter screen 3 is higher than the normal water level of the condenser and lower than the highest water level of the condenser.
The difference of this embodiment filter screen and conventional condensate pump entry filter screen (shown in fig. 1) lies in changing entry pipeline filter screen mounted position into condenser hot-well department, has effectively reduced condensate pump inlet pressure, and then has reduced the electric energy of condensate pump consumption.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
