High-accuracy and portable micro-hardness detection device of boiler water

Abstract

The invention relates to a high-accuracy and portable micro-hardness detection device of boiler water. The high-accuracy and portable micro-hardness detection device comprises a box body (1) and a hardness testing unit (2), wherein the hardness testing unit (2) is arranged in the box body (1); the color of an inner plate of the box body (1) is white; and the inner plate is used as a color matching bottom plate for titration operation. The hardness testing unit (2) comprises a liquid feeding bottle assembly (21), a trace pipette (22), a sampling bottle (23), a tapered bottle (24) and a testing reagent bottle (25); the device further comprises a vibration-absorption lining (3); the vibration-absorption lining (3) is filled into gaps among the liquid feeding bottle assembly (21), the trace pipette (22), the sampling bottle (23), the tapered bottle (24) and the testing reagent bottle (25). Compared with the prior art, the device is light in weight and convenient to carry and can prevent external pollution; and the accuracy of a testing result is effectively improved.

Description

technical field [0001] The invention relates to a hardness detection device, in particular to a high-accuracy portable boiler water micro hardness detection device. Background technique [0002] At present, there are a variety of hardness test boxes on the market, but all of them are used to detect high hardness in water, which is not suitable for the micro hardness test requirements of boiler water in thermal power plants. There are mainly the following deficiencies: [0003] 1) Hardness testing requires a variety of equipment and agents, which are inconvenient to carry, making it difficult to carry out micro hardness testing on site. [0004] 2) The micro hardness operating device, placed on site, is easily polluted, resulting in low accuracy of on-site testing results. [0005] 3) The operation steps are cumbersome, and the test operators need to be trained in advance. In case of emergencies, there may be no laboratory technicians who can master the titration skills, etc...

Problems solved by technology

[0002] At present, there are many kinds of hardness test boxes on the market, but all of them are used to detect high hardness in water, which are not suitable for the micro hardness test requirements of boiler water in thermal power plants, and mainly have the following deficiencies:

[0003] 1) Hardness testing requires a variety of equipment and chemicals, which is inconvenient to carry, making it difficult to carry out micro-hardness testing on site

[0004] 2) The micro hardness operating device is placed on site, which is easily polluted, resulting in low accuracy of on-site test results

[0005] 3) The operation steps are cumbersome, and the test operators need to be trained in advance. In the event of an emergency, it may be impossible to find a laboratory technician who can master the titration skills, thereby delaying the timing and unable to accurately determine whether the boiler condenser tube is leaking
