Problems solved by technology

The conventional operation of measuring density is to use a glass measuring cylinder to take the liquid sample to be measured, place the glass measuring cylinder on a horizontal and fixed platform, put the density meter into the glass measuring cylinder, observe and record the density, and finally pour the liquid sample to a fixed At the collection point, it can be seen that the whole process of measuring density is cumbersome. If there are many types of liquid samples, the operation frequency of density measurement is high (such as desulfurization liquid sampling at least once per hour), and most of these liquid samples are corrosive or toxic. , the sampling process is easy to cause harm to the human body, and the measurement personnel need to wear protective gloves and protective masks before sampling

Embodiment 1

[0035] Such as Figure 4As shown, the liquid-taking tank 1 is made of transparent material, and the baffle 4 is detachably connected with the liquid-taking tank 1. When measuring the density, the baffle 4 is inserted into the liquid-taking tank 1 so that the liquid-taking tank 1 is divided into full flow Chamber 2 and observation chamber 3 are two parts. When cleaning the liquid-taking tank 1 after the measurement is completed, the baffle 4 is removed, and the baffle 4 and the liquid-taking tank 1 are cleaned separately.

[0036] In this embodiment, the baffle 4 is provided with a communication hole 5, the communication hole 5 is located at the bottom of the baffle 4, the communication hole 5 is a square hole 51, and the communication hole 5 is provided at the bottom of the baffle 4. 2, the sample liquid enters the observation chamber 3 through the communication hole 5 at the bottom of the baffle 4 at the same time.

[0037] Alternatively, the baffle plate 4 is provided with ...

Embodiment 2

[0040] Such as Figure 5 As shown, the liquid sampling tank 1 is made of transparent material, and the liquid sampling tank 1 is provided with a sampling cover 6, which is detachably connected with the liquid sampling tank 1, and the sampling cover 6 is provided with a density measurement through hole 62 and at least one sampling through hole 61, the density measurement through hole 62 is arranged directly above the observation chamber 3, the sampling through hole 61 is arranged directly above the full flow chamber 2, the density meter is inserted into the observation chamber 3 through the observation hole, and the sampling pipeline Inserted into the sampling through hole 61 and the sampling pipeline leads into the full flow cavity 2 .

[0041] Preferably, the sampling cover plate 6 is provided with two sampling through holes 61, which are respectively a first through hole and a second through hole. Connect the sampling pipeline of the liquid to be tested waiting for the subs...

Embodiment 3

[0044] On the basis of embodiment 1 or embodiment 2, such as Figure 6 As shown, the liquid taking tank 1 is made of transparent material, and the outer wall of the observation chamber 3 is provided with an overflow pipe, which is connected to the overflow port 31, and the outlet of the overflow pipe faces downward, and the overflow pipe can also be connected to the sample The recovery device is connected, and an overflow pipe is provided on the outer wall of the observation chamber 3 to prevent the sample liquid from polluting the outer wall of the liquid-taking tank 1 when it overflows.

[0045] The method for measuring density using a liquid sampling device is described in conjunction with the above-mentioned embodiments, and the steps are as follows,

[0046] Place the liquid sampling tank 1 in the sampling horn, open the valve of the emptying pipe under the sampling horn, and place the full flow cavity 2 of the liquid sampling tank 1 under the sampling point. The sampling...

The liquid sampling device disclosed by the invention has the advantages of self-cleaning and self-moistening.

Description

technical field [0001] The invention relates to the technical field of density measurement, more specifically, it relates to a liquid sampling device and a density measurement method. Background technique [0002] At present, my country has made mandatory regulations on energy conservation and environmental protection, requiring coal-fired boilers to perform desulfurization and dust removal on flue gas. The conventional flue gas desulfurization process uses alkaline solution (sodium hydroxide solution is generally used) to react with the sulfur-containing gas in the flue gas to achieve desulfurization treatment. Therefore, ensuring the concentration of alkaline solution is one of the keys to achieve desulfurization treatment. Liquids that require density measurement in the desulfurization process include rich liquid, lean liquid, vacuum condensate, sodium hydroxide solution, and washing cycle liquid. The conventional operation of measuring density is to use a glass measurin...
