Abstract
The two vacuum pump cooling water source of a kind of a-worker-a-backup, belongs to power generating equipment transformation field.The purpose of this utility model installs two jacket water loop body systems additional, namely can cool simultaneously, the two vacuum pump cooling water source of the a-worker-a-backup that can cool respectively again.Steam-water separator of the present utility model is connected with main heat exchanger and auxiliary heat exchanger respectively by pipeline, and main heat exchanger and auxiliary heat exchanger communicate with vacuum pump respectively by pipeline again, and the water outlet of vacuum pump is connected with the water inlet of steam-water separator; Enclosed cooling water recirculation system stretches into main heat exchanger inside, and is provided with valve in enclosed cooling water recirculation system; Open type cooling water recirculation system stretches in auxiliary heat exchanger, and the pipeline that open type cooling water recirculation system is connected to auxiliary heat exchanger is provided with filter and valve.The utility model provides due to the efficiency of vacuum pump, and the vacuum values of unit reduces greatly, thus adds Economy and the working life of unit.
Description
Technical field
The utility model belongs to power generating equipment transformation field.
Background technique
Most important in the cooling of power station vacuum pump, directly affect the working efficiency of vacuum pump, existing power station is adopt conventional water flowing cooling substantially, does not namely reach the effect of cooling, also likely produces danger, and had a strong impact on the working efficiency of vacuum pump.
Summary of the invention
The purpose of this utility model installs two jacket water loop body systems additional, namely can cool simultaneously, the two vacuum pump cooling water source of the a-worker-a-backup that can cool respectively again.
Steam-water separator of the present utility model is connected with main heat exchanger and auxiliary heat exchanger respectively by pipeline, and main heat exchanger and auxiliary heat exchanger communicate with vacuum pump respectively by pipeline again, and the water outlet of vacuum pump is connected with the water inlet of steam-water separator; Enclosed cooling water recirculation system stretches into main heat exchanger inside, and is provided with valve in enclosed cooling water recirculation system; Open type cooling water recirculation system stretches in auxiliary heat exchanger, and the pipeline that open type cooling water recirculation system is connected to auxiliary heat exchanger is provided with filter and valve.
The utility model install additional two covers to vacuum pump cooling system and can work simultaneously, can work respectively again, when requiring to increase working efficiency, just open two cover systems to work simultaneously, when set of system needs repairing, then close the circulatory system that need keep in repair, another set of system is allowed to carry out cooling work, because the efficiency of vacuum pump provides, the vacuum values of unit reduces greatly, thus adds Economy and the working life of unit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Steam-water separator 1 of the present utility model is connected with main heat exchanger 5 and auxiliary heat exchanger 7 respectively by pipeline, and main heat exchanger 5 and auxiliary heat exchanger 7 communicate with vacuum pump 6 respectively by pipeline again, and the water outlet of vacuum pump 6 is connected with the water inlet of steam-water separator 1; It is inner that enclosed cooling water recirculation system 4 stretches into main heat exchanger 5, and be provided with valve in enclosed cooling water recirculation system 4; Open type cooling water recirculation system 3 stretches in auxiliary heat exchanger 7, and the pipeline that open type cooling water recirculation system 3 is connected to auxiliary heat exchanger 7 is provided with filter 2 and valve.
So-called enclosed cooling water recirculation system is other device cooling systems that original power generating equipment carries.
So-called open type cooling water recirculation system is the water circulation system be connected with existing external source, because external water source contains a large amount of impurity, has so just installed filtrating equipment purified water source additional.
The utility model is by the transformation to cooling water source, and every platform unit improves vacuum 1.2KPA, and every 1KW saves and marks 3.6 grams, coal, calculates according to electricity in this year 2500000000, and annual saving altogether marks 9000 tons, coal, according to the calculating of 500 yuan, mark coal per ton, economizes on the use of funds 4,500,000 yuan.This transformation amounts to generation expense 4.5 ten thousand yuan.
