A comprehensive simulation test system for water quality of circulating pipe network with temperature control system

Abstract

The invention discloses a circulating pipe network water quantity integrated simulation test system with a temperature control system. The system comprises a water supply subsystem and an independent circulating pipe network subsystem; the water supply subsystem comprises a first water supply tank and a second water supply tank, wherein the first water supply tank is provided with a water inlet, a water outlet and an agent injection port, and the second water supply tank is communicated with the first water supply tank by using a pipeline with a second valve and provided with a water inlet, awater outlet and an agent injection port; the independent circulating pipe network subsystem is a loop comprising a main circulating pump, an electromagnetic flow meter and a high-level water supply and exhaust water tank connected in series through a pipeline; and the loop is connected with a first pipeline branch for realizing closed circulation, a water supply system, an emptying branch, a water quality monitoring system and the temperature control system. The pipeline of the independent circulating pipe network subsystem is connected with an agent injection system. The circulating pipe network water quantity integrated simulation test system with the temperature control system has the advantages of high simulation degree and capability of simulating multiple actual municipal water supply pipe network system working conditions by cooperation of the components.

Description

technical field [0001] The invention relates to the technical field of a test simulation system for a drinking water supply pipe network, in particular to a water quality comprehensive simulation test system for a circulating pipe network with a temperature control system. Background technique [0002] The water supply pipe network is an important part of the urban water supply system. Its function is to deliver water that meets the national drinking water quality standards after being purified by the water plant to the user terminal. The water quality indicators of most waterworks in my country can meet or exceed the national drinking water quality standards, but when it is delivered to users through the pipe network, it often fails to meet the standards and even endangers the health of users. According to the data, the water quality of the water plant shows a trend of decreasing obviously from the factory to the user, mainly manifested in the increase of the content of iro...

Problems solved by technology

The reservoir is not only a test raw water deployment pool but also has the function of exhaust gas. However, the built-up open circulation pipe network test system is generally small in scale, the cycle design is very simple, and the cycle loop is short. In essence, it cannot be regarded as a high simulation. Comprehensive simulation test system for water quality of circulating pipe network

Specifically, there are mainly poor simulations of water flow conditions in the design (every time the circulating water sample flows through the reservoir, it is in contact with the air in a large area, which will affect the quality of the circulating water; and the raw water pool participates in the pipe network cycle test, and the water flow conditions are different from the actual pipe network. There are certain differences), insufficient control of conditions (for example, it is impossible to pressurize the full pipe flow in the circulation pipeline, and it is impossible to simulate the pressurized operating environment of
