Energy-saving ball-loading and ball-serving device for condenser glue ball cleaning system

Abstract

The invention discloses an energy-saving ball-loading and ball-serving device for a condenser glue ball cleaning system, comprising a shell and a viewing end cover. An annular throttle partition board is arranged in the shell; a bottom plate of the shell is fixedly connected with one end of a filtering screen; the other end of the filtering screen is fixedly connected with one end having a smaller diameter of a hopper; a gap is reserved between the filtering screen and an inner hole of the throttle partition board; a plurality of through holes are formed in the hopper and a side wall of the filtering screen; a ball outlet is formed in the bottom plate of the shell; two pipe mouths are fixedly connected to the side wall of the shell and are respectively connected with a valve; another two valves are connected with the ball outlet and are respectively communicated with a ball-selection sieve mesh and a circulation cooling water inlet pipeline; hand holes are formed in the viewing end cover or the side wall of the shell; and a detachable sealing mechanism is arranged on the hand hole. According to the device, through the valve corresponding to intermittent on / off, a glue ball centrally enter the circulation cooling water inlet pipeline, so that the cleaning effect is improved, the number of the circulation cooling water inlet pipeline, into which heated circulation cooling water enters, is reduced, and the circulation cooling effect of the condenser is improved; and in addition, the valve can be controlled by PLC (Programmable Logic Controller).

Description

technical field [0001] The invention belongs to the technical field of manufacturing circulating cooling water systems in thermal power plants, and relates to a ball loading and serving device for a rubber ball cleaning system inside a cooling pipe of a surface heat exchanger, in particular to a circulating cooling water system for a steam turbine island condenser in a thermal power plant The rubber ball cleaning system and other industrial cooling system surface heat exchanger rubber ball cleaning system ball loading and serving device. Background technique [0002] Most of the existing steam turbine condenser circulating cooling water systems in thermal power plants have adopted rubber ball cleaning systems. It can timely and effectively remove the impurities and dirt attached to the inner wall of the heat exchange tube of the circulating cooling water of the condenser, improve the cleanliness of the inner wall of the heat exchange tube, thereby improving the heat exchange...

AI Technical Summary

Problems solved by technology

Although the end cover of the ball loading chamber is fastened by means of slip bolts, etc., the labor intensity is relatively high

The second is that when it is necessary to identify the rubber balls, the rubber balls trapped on the filter screen inside the ball loading room need to be manually removed, which increases the physical labor of the staff. Especially in winter, the rubber balls need to be cleaned manually. Cold water is harmful to the health of the operators. Adverse effects

The third is that the outlet of the ball chamber is connected to the water inlet pipe of the condenser circulating cooling water. During the operation of the rubber ball cleaning system, the water absorbed by the cooling water pipe inside the condenser is pumped through the ball pump to flow through the ball The chamber then enters the condenser circulating cooling water inlet pipe, which not only squeezes out the low-temperature water entering the condenser, but also causes a certain amount of high-temperature water to mix into the low-temperature water. Although the temperature of the circulating water inlet is slightly increased, the condensation is reduced. The overall cooling effect of the vaporizer is not conducive to the improvement of vacuum degree

Electric device is required to operate the rotating sieve tray, which is complex in structure
