Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Example (b): a disassembly-free cleaning structure applied to fluid measurement comprises a bottom plate 1 and a flange cover 2 externally connected with a connecting pipe 21, wherein a groove communicated with the connecting pipe 21 is formed in the bottom plate 1, and the groove and the connecting pipe 21 form a measurement channel;
a measuring device 3 is connected in the measuring channel in a sliding manner, and the measuring device 3 in the embodiment takes ph as an example;
the end part of the measuring device 3 close to the bottom plate 1 is fixedly connected with a blocking block 33, and the blocking block 33 is of a solid structure and is shown in the figure 1;
the front end of the measuring device 3 is provided with a measuring head 31, the specific position of which is shown in fig. 2 and is located at the rear end of the blocking block 33, and both sides of the measuring device 3 where the position of the measuring head 31 is installed are of a penetrating structure, that is, the measuring head 31 can be communicated with the outside and can be directly contacted with fluid when being located in a fluid pipeline.
The end part of one side of the measuring device 3, which is far away from the bottom plate 1, is connected with a driving piece 4 for pushing the measuring device 3 to linearly slide back and forth in the measuring channel;
the inner wall of the measuring channel is embedded with two groups of sealing rings 32, the two groups of sealing rings 32 are distributed up and down, and referring to the figure, a cleaning channel is defined by the two groups of sealing rings 32;
a cleaning medium inlet and a cleaning medium outlet are formed in the cleaning channel, and both the cleaning medium inlet and the cleaning medium outlet are located on the connecting pipe 21 in this embodiment.
The cleaning medium inlet and the cleaning medium outlet are connected to the medium storage tank to form a circulation path, and a circulation pump is installed on the circulation path. The media storage bin is secured in position proximate the measurement point.
The working principle is as follows: taking a desulfurizing tower as an example, after the pipeline is modified, the main body of the device is mounted on the modified pipeline, that is, in the state of fig. 2, the bottom plate and the flange cover 2 are fixed outside the pipeline C (refer to the method disclosed in patent 2019103657075);
when a significant drop in the sensitivity of the ph meter is detected (or whether fouling is inferred from the time the ph meter is in the pipe), the double-headed hydraulic cylinder is opened, the ph meter is retracted (i.e. moved downwards according to the ph meter in fig. 2) until the block 33 is in sealing contact with the upper sealing ring 32 (note that the lower sealing ring 32 is always in sealing contact with the outer wall of the measuring device 3), a sealed cleaning passage is formed between the block 33 and the sealing ring 32 (the seal here is the seal with the pipe C and with the drive element 4), the circulation pump on the circulation passage is opened to introduce the cleaning medium from the medium inlet a to clean the measuring head 31, and finally the medium is returned to the storage tank from the point B.
In this embodiment, taking the limestone-gypsum desulfurization system as an example, the ph meter is used for measuring alkaline slurry in the circulating pipeline, so the cleaning medium may be an acidic solution (such as hydrochloric acid), and it can be determined that the cleaning is completed when the reading of the ph meter is stabilized at an acidic reading during the cleaning; the measuring head 31 is pushed into the pipe C when the double-headed hydraulic cylinder is activated.
