Abstract
The invention discloses an installation method of a physically polarized water treatment apparatus in a circulating cooling water system. The method effectively solves a disadvantage that the polarized water treatment apparatus must be arranged in the outage state of the circulating water system, and also solves the disadvantages of large construction difficulty, long period and high comprehensive cost. The physically polarized water treatment apparatus 1 can be arranged in a forebay 11 in front of a circulation water pump group 6 in the normal running state of the circulating water system without influencing normal production, so time and labor are saved, the working efficiency is improved, and the construction cost and the construction risk are reduced. The method has good application prospect.
Description
Technical field
The present invention relates to the installation method of physics polarized water treatment unit in recirculating cooling water system, be widely used in power station, heat power plant, metallurgical, the circulating water cooling system of chemical industry.
Background technology
For the circulating water cooling system of generator sets in power plant, because physics polarized water (hereinafter referred to as polarized water) treatment technology utilizes physical field to act on recirculated cooling water, glassware for drinking water after this device processes has good antiscale, algae removal sterilization and corrosion mitigating effect, instead of traditional in recirculated cooling water, to throw in pharmaceutical chemicals.Cost-saving, reduce sewage discharge, water-saving benefit is obvious.But polarized water treatment unit is in the past installed wastes time and energy, carry out under the state must stopped transport in circulating water system.Polarized water treatment unit installation site is in the past mounted on the pipeline between recycle pump group and condenser.On pipeline, installation site has two kinds usually: position one, according to the size of polarization body water treatment device, first excavate a rectangle hole at the ground location laying circulating water pipeline, circulating water pipeline is exposed, surrounding and the bottom cement in hole are built and do WATER REPELLENT, make rainproof WATER REPELLENT above.The size in hole depends on polarization body size and Construction and Maintenance space.Position two, locates at more than the ground level that exposes of circulating pipe.Construction procedure is roughly: 1, stoppage in transit circulating water system; 2, pipeline internal water accumulation is drained; 3, cut off circulating pipe by polarized water treatment unit size and on the circulating pipe of polarization body both sides, stay maintenance construction manhole; 4, the fracture of polarized water treatment unit and circulating water pipeline to be matched position with crane, do external welding in tube wall weld seam; 5, build manhole plate, do the water test.This construction period was about about 30 days, and difficulty of construction is large, long construction period, and construction process danger coefficient is large, and comprehensive cost is large, and polarized water treatment facility maintenance each time, circulating water system must be stopped transport and just can carry out, delay normal production.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, the installation method of physics polarized water treatment unit in recirculating cooling water system is provided, the technical solution adopted for the present invention to solve the technical problems is, it is characterized in that: polarized water treatment unit installation process is carried out under circulating water system normal operating condition, installation site is in forebay 11, physics polarized water treatment unit 1 and the joint portion of forebay intake are provided with gasket 2, physics polarized water treatment unit 1 is entered in forebay 11 from forebay 11 upper lifting, in lifting physics polarized water treatment unit 1 decline process, by water circulating pump group 6 work current suction force and the suspension hook Parallel to the flow direction slight shift power produced at forebay 11 place to condenser 9 direction is produced with joint efforts, physics polarized water treatment unit 1 is moved into place to forebay 11 with current suction force, by means of equipment own wt and the frictional force with ground, the gasket 2 of physics polarized water treatment unit 1 tail end is connected with the wall of forebay 11 and the tight-lipped close of water circulating pump group, complete installation work, now recirculated water all enters water circulating pump group 6 and circulating water pipeline 8 by physics polarized water treatment unit 1, and enter condenser 9 and carry out heat exchange, recirculated water after heat exchange flows to water cooling tower 4 spraying cooling finally by return water pipe 10.
The invention has the beneficial effects as follows, the installation of polarized water treatment unit and maintenance carry out under circulating water system normal operating condition, do not affect normal production, time saving and energy saving, is convenient to install, and improves working efficiency, reduce construction cost and risk.
