Three-stage temperature control cooling water tank

Abstract

The invention relates to a three-stage temperature control cooling water tank. The three-stage temperature control cooling water tank comprises a tank body for containing cooling water, wherein the interior of the tank body is divided into a first tank body, a second tank body and a third tank body by a first partition plate and a second partition plate; a first heating device is mounted in the first tank body, a drain pipe is mounted at the bottom, and a water return pipe and a water replenishing pipe are mounted at the top; a second heating device is mounted in the second tank body; a third heating device is mounted in the third tank body, an overflow pipe is mounted at the upper part of the side wall of the third tank body, a water supply pipeline is mounted at the lower part, the drain pipe and the overflow pipe are connected with a drainage pipe, the bottom of the first tank body is communicated with the bottom of the second tank body, and the top of the second tank body is communicated with the top of the third tank body. The three-stage temperature control cooling water tank provided by the invention is designed against the temperature control range of the cooling water tank, which is required for the experiments, fully utilizes the characteristic of rich industrial water sources in a power plant, and directly uses a method of injecting water at normal temperature to cool the circulating cooling water; compared with the traditional cooling water tank, a compressor is omitted, so that the space is saved.

Description

technical field [0001] The invention relates to the field of control, in particular to a three-stage temperature-controlled cooling water tank used in flue gas heat exchange experiments at the tail of a power plant. Background technique [0002] The cooling water tank is a commonly used instrument and equipment in the industrial and scientific research fields. In some occasions that require precise control of the cooling process parameters, such as laser cavity cooling or some scientific experiments, it is often necessary to feed cooling water with a constant temperature into the cooling pipe. . [0003] Commonly used cooling water tanks generally have two characteristics: 1. The cooling water is generally recycled, and the cooling water needs to be cooled. The cooling method is often to use a cooling device, such as compressor cooling or heat exchanger cooling. However, these cooling devices Generally, the volume is relatively large, and the use of additional cooling devic...

Problems solved by technology

In this experiment, due to the complex composition and high temperature of the flue gas at the tail of the boiler, it is difficult to build a simulation test bench in the laboratory, so the experiment is mainly completed in the actual operating environment of the power plant, and the experimental conditions are subject to many restrictions

For example, the layout of power plants is generally very compact, and the operating space is small. Conventional cooling water tanks with compressors are not suitable for this kind of workplace. On the other hand, the experimental conditions of power plants are simple and the environment is noisy. Experimenters hope to use as simple a control method as possible. completed experiment
