Technical Field
The utility model belongs to the evacuating device field, specifically speaking relates to a condenser evacuating device of getting rid of pipeline ponding.
Background
In the power generation production process of the condensing steam turbine set of a thermal power plant and a gas power plant, the vacuum degree of the condenser is an extremely important index, and the phase change of the vacuum degree of the condenser determines the power generation cost and the power supply coal consumption.
And the effect of the vacuumizing equipment is to continuously pump out air and other non-condensable gases from the condensing equipment in time during the operation of the condensing turbine so as to ensure the heat exchange efficiency of the heat exchange tube of the condenser and maintain the vacuum degree. The performance of the vacuum pumping equipment directly determines the exhaust pressure of the condensing steam turbine, and further influences the enthalpy drop of the unit and the steam consumption.
However, in the currently commonly used vacuum pumping equipment, such as a water ring vacuum pump, a roots pump, etc., because the vacuum pumping equipment is insensitive to a small amount of water vapor contained in the pumped gas, water accumulation is easily generated during vacuum pumping, the water accumulation generated in the vacuum pumping pipeline can greatly affect the output of the vacuum pumping equipment, and the vacuum degree of a turboset is further affected due to the reduction of the output of the vacuum pump, so that the energy consumption of the generator set is increased, and the power supply cost is increased.
The existing vacuum pumping equipment of the steam turbine set mainly comprises a water jet air extractor, a steam jet air extractor, a mechanical vacuum pump, a combined vacuum pump and the like, wherein the combined vacuum pump is mostly combined by a roots pump and a water ring vacuum pump.
Therefore, aiming at the common combined pump in the existing equipment, a new scheme which can remove accumulated water in the vacuum pipeline without influencing the vacuum pumping effect and has small change amplitude is needed.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem that prior art exists, the utility model aims to provide a can get rid of condenser evacuating device of pipeline ponding.
In order to solve the above problem, the utility model discloses the technical scheme who adopts as follows:
the utility model provides a can get rid of condenser evacuating device of pipeline ponding, includes condenser, first vacuum pump and water ring vacuum pump, the evacuation pipeline of condenser link to each other with first vacuum pump, the output of first vacuum pump link to each other with first condenser, the output of first condenser link to each other with water ring vacuum pump's input, first condenser bottom be equipped with ponding and get rid of the pipeline and link to each other with water ring vacuum pump.

Detailed Description
The present invention will be further described with reference to the following specific embodiments.
As shown in fig. 1, the present invention mainly includes a first vacuum pump, a second vacuum pump, and a subsequent exhaust treatment section.
The utility model discloses mainly used is condensing turbine unit's condenser among thermal power plant, gas power plant.
When the condenser works, the corresponding vacuum degree needs to be kept, and the condenser is vacuumized through the vacuumizing pipeline 1. The condenser evacuation pipeline 1 is connected with a first vacuum pump, in the embodiment, a Roots vacuum pump 2 is adopted, and the first vacuum pump directly pumps gas in the condenser, so that steam is inevitably sucked into the vacuum pump, and a first condenser 3 is connected to the output end of the first vacuum pump to be used as an interstage condenser, so that condensed water is prevented from being accumulated in the pipeline of the vacuum pump.
The output end of the first condenser 3 is connected with a second vacuum pump, in this embodiment, a water ring vacuum pump 4 is adopted, and the output end of the water ring vacuum pump 4 is connected with a steam-water separator 5. The steam-water separator 5 and the second condenser 6 form a working part of the water-ring vacuum pump 4, the water level balance of the water-ring vacuum pump 4 and the steam-water separator 5 is maintained, the steam-water separator 5 is maintained within a normal range through an automatic water replenishing valve and an overflow pipe, the water-ring vacuum pump 4 is enabled to operate under the optimal working condition, and the output and the efficiency of the water-ring vacuum pump 4 are guaranteed.
The bottom of the first condenser 3 is provided with a accumulated water discharge pipeline 7, the other end of the accumulated water discharge pipeline 7 is connected with the water ring vacuum pump 4, accumulated water in the first condenser 3 is pumped out through high vacuum in the water ring vacuum pump 4, and accumulated water in a pipeline in the vacuum pumping equipment is avoided.
The water ring-roots vacuum pump combination adopted in the embodiment integrally pumps out gas in the condenser through the vacuum functions of the water ring vacuum pump 4 and the roots vacuum pump 2, so that the vacuum degree of the condenser is maintained. Then set up first condenser 3 behind roots vacuum pump 4 and condense the gas of taking out, prevent that steam from condensing ponding in the pipeline. Then, a ponding discharge pipeline 7 is arranged at the bottom of the first condenser 3 and connected with the water ring vacuum pump 4, and the ponding in the first condenser 3 is pumped out through the high vacuum in the water ring vacuum pump 4. In addition, since water needs to be added into the water ring vacuum pump 4 for work, the working part of the water ring vacuum pump 4 can automatically maintain water level balance, and the extra-extracted accumulated water does not affect the normal operation of the water ring vacuum pump 4. Thereby realize can also getting rid of the ponding in the evacuation equipment when normal work, guarantee evacuation system's evacuation efficiency.
