A condenser rubber ball cleaning system

Abstract

The invention discloses a condenser rubber ball cleaning system. The condenser rubber ball cleaning system comprises a ball soaking chamber, a screening chamber, a rubber ball conveying photoelectriccounting device, a centralized ball conveying chamber and a ball recycling chamber, wherein the ball soaking chamber is used for screening rubber balls which are unqualified in density and conveying the rubber balls with qualified density to the screening chamber; the screening chamber is used for screening the rubber balls which are unqualified in diameter and conveying the rubber balls with qualified diameter to the centralized ball conveying chamber through the rubber ball conveying photoelectric counting device; the centralized ball conveying chamber is used for receiving the qualified rubber balls and conveying the same to a condenser cooling water inlet; the ball recycling chamber is used for recycling the rubber balls at a condenser cooling water outlet; the rubber ball conveying photoelectric counting device is used for recording the number of the conveyed balls and the recycled balls and transmits the data to a DCS system or a PLC device to automatically statistically calculate ball recycling rate.

Description

technical field [0001] The invention relates to the field of condenser rubber ball cleaning, in particular to a condenser rubber ball cleaning system. Background technique [0002] The function of the rubber ball cleaning system of the condenser of the wet-cooled steam turbine unit in the thermal power plant is to clean the cooling pipe in the condenser, keep the cleanliness of the cooling pipe, and improve the heat exchange capacity of the condenser. [0003] The working process of the conventional rubber ball cleaning system is: artificially bubble the ball, make the size and density of the ball meet the requirements, that is, the diameter of the ball is slightly larger than the cooling tube of the condenser by a certain value, and the ball cannot float on the water surface; manually determine the qualified rubber ball The number of qualified rubber balls is put into the cleaning system, and the rubber balls enter the condenser cooling pipe one after another; after cleanin...

AI Technical Summary

Problems solved by technology

[0005] 1. After soaking the balls, manually screen the rubber balls with qualified density and size, which requires a lot of work and a high error rate. The accuracy of the selection of qualified rubber balls depends on the responsibility of the personnel

If the personnel have poor sense of responsibility, putting rubber balls with too large or too small diameter or floating on the water surface into the cleaning system will lead to poor cleaning effect. Even if the system runs continuously, it will not be able to achieve a good cleaning effect.

[0006] 2. The number of rubber balls counted by personnel is heavy and the accuracy rate is low, which may lead to inaccurate ball collection rate

[0007] 3. The release method of the rubber balls is unreasonable. The rubber balls entering the condenser one after another move with the cooling water flow. The more serious the blockage of the internal cooling pipe of the condenser, the lower the inlet water flow rate, and the less rubber balls enter; the cleaner the The higher the flow rate of water at the inlet of the cooling pipe, the more rubber balls will enter. In the end, only part of the cooling pipe will be cleaned well, and the overall heat exchange efficiency of the condenser is difficult to guarantee.

[0008] 4. The rubber ball cleaning system generally operates regularly or continuously, without considering the cleaning effect and cleaning timing, resulting in an increase in operating costs, such as: increased power consumption of the rubber ball pump, consumption of rubber balls, and premature aging of rubber ball cleaning system equipment Wait

[0009] 5. It is relatively random for personnel to operate the rubber ball cleaning system, and the personnel with poor sense of responsibility may not even put it into operation or keep it in operation, regardless of the cleaning timing and cleaning effect
