Energy-saving and antifouling reforming method and system with roof tank and feed pipe

Abstract

The invention relates to an energy-saving and antifouling reforming method and a reforming system with a roof tank and a feed pipe. The reforming method comprises the following steps: 1, prophase preparatory stage; 2, metaphase reforming stage; and 3, late stage run phase. The reforming system comprises a water chamber, an air chamber, a communication sleeve, a reinforcement pipe, a bypass pipe and an intelligent liquid level control valve, wherein the water chamber and the air chamber have different functions without mutual influence and can cooperate closely to work; and simultaneously, the surplus pressure head of municipal pipe net is utilized to directly supply water to users, thus ensuring no water break during cleaning or maintaining or reforming the water tank and not influencing the daily domestic water for residents, reducing cleaning times of the water tank, saving energy and reducing emission. Breathing equipment with a built-in assembled flexible liner bag is installed and used in the air chamber to ensure the water to run in an air-tight state, thus completely avoiding secondary pollution caused by the contact of water during flowing in or out of the water tank with air outside the tank, and also eradicating the problem of beneficial residual chlorine volatilization caused by an opening type.

Description

technical field [0001] The invention relates to existing roof water tanks and water supply pipes, in particular to an energy-saving and antifouling retrofit method and system for existing roof water tanks and water supply pipes. Background technique [0002] As a widely used water supply method, the current roof water tank has the functions of "water supply", "peak shaving" and "emergency preparation". It is a "black, big and clumsy" brick-concrete and steel-concrete structure. The roof water tanks of other houses also have the form of glass fiber reinforced plastic, plastic and stainless steel; but most of these water tanks are flat-bottomed and open, without measures to prevent secondary pollution, and are only used as water tanks. It is just a container of water in the physical sense. [0003] Due to the water supply pipes of the existing roof water tanks, the water inlet pipes and outlet pipes of the water tanks are generally separated and not connected in the middle, f...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: to overcome the ubiquitous flat-bottomed open type of the above-mentioned existing roof water tank, without sealing, it is easy to produce secondary pollution and residual chlorine volatilization and waste, and the water inlet pipe and the water outlet pipe of the water tank are not connected because the middle is not connected. Caused the loss and waste of the residual pressure head in the water supply pipe network; and providing a method that does not completely eliminate and replace the original water tank, and does not affect the daily life of the existing residents, can improve the water quality standard, at least maintain the same level as The water quality from the original waterworks remains the same, strive to meet the EU secondary standard, reduce the number of tank cleanings, and meet the general requirements of low-carbon economy, healthy people's livelihood projects, an energy-saving and anti-fouling retrofit method and system for existing roof water tanks and water supply pipes
