SU17287A1 - Apparatus for replenishing shortage and controlling the temperature of cooling water in condensing units - Google Patents

Description

To regulate the temperature and replenish the lack of cooling water in condensation plants (in case of expansion of the plant without a corresponding expansion of hydraulic structures supplying water to the pools, cleaning of water lines, etc.) without reverse cooling, the invention proposes to divide the cooling water pool into two interconnected parts, where water is taken for supplying to condensers from one part of the basin, and to the other fresh water and additional water from the discharge channel.

In FIG. 1 shows a vertical section of a small pool along line A-B in FIG. 2 in the case of using a device from two separate pools; FIG. 2- pool plan; FIG. 3 is a vertical section of the pool along line -4-B in FIG. 4, in the case of a single basin divided by a partition into two parts; FIG. 4-pool plan in the latter case ..

With a lack of cooling water in case of expansion of the installation, instead of a new additional hydraulic structure, a device is proposed for

using the waste water in the condenser, which, using an auxiliary hose from the drain channel, returns back to the pool in the required missing quantity and is mixed with fresh cooling water. For these purposes, the pool for cooling water (Figs. 3, 4) is divided into two parts by means of a partition, communicating with each other through a window. Fresh and additional waste water flows into part 1, where it mixes and passes into part I, from where it is taken up by circulation pumps for supply to the condenser. In another design (Figs. 1, 2), fresh and waste water flows into a separate small pool, where it is mixed and transferred into a large pool, and from the latter is pumped into condensers.

To regulate the flow of wastewater into the pools, a booster or rotating gate must be installed on the auxiliary hose, allowing this adjustment to be made according to the level of the pool water;

The proposed device is meant to be applied in the case of a lack of cooling water when cleaning the water lines and

filters. At the same time, for the time of cleaning, the corresponding conduit is plugged, and the water is supplied by other conduits and is added along the auxiliary hose with waste water in an amount to compensate for the output of one water supply to fresh water.

Subject Patent a.

1 A device for replenishing the deficiency and controlling the temperature of the cooling water in condensing units without reverse cooling water, characterized in that the cooling water basin is divided into two separate pools (Fig. 1, 2) or a partition with a communication window ( Fig. 3, 4), in which device the cooling water is taken from the large pool (Fig. 2) or from part II (Fig. 4), fresh water and additional water from the drain channel is introduced into a smaller pool (Fig. 2) or part I (Fig. 4.
