Abstract
The utility model discloses an online leak detector, including cooler and knockout drum, the knockout drum is higher than the cooler setting, the export of cooler and the entry linkage of knockout drum, and the sample connection and the discharge opening department of knockout drum are equipped with the ooff valve respectively, and the external normal atmospheric temperature water of coolant entry of cooler, the entry of cooler still are connected with the connecting pipe, and the connecting pipe is used for connecting the sample connection of waiting to examine equipment. The online leak detector detects online.
Description
The technical field is as follows:
the utility model relates to a detection area specifically says to an online leak detector.
Background art:
the production device is provided with a unit of a heat exchanger, and when the leakage of the heat exchanger is detected, the conventional method needs to stop the production of the whole device or a certain unit, and then the device is washed clean by alkali and water to carry out a pressure test; if the whole device has more heat exchangers, a parking mode is initially adopted to carry out pressure test on each heat exchanger, helium leakage detection is carried out, the cost is more, the time is long, the target range is too large, and the error is large.
The utility model has the following contents:
the utility model aims to solve the technical problem that an online leak detector of convenient on-line measuring is provided, this online leak detector can carry out investigation one by one to every or a plurality of heat exchanger, pipeline on line, finally confirms leakage equipment, has reduced the loss and the check-out time and the expense of stopping production.
The technical solution of the utility model is that, an online leak detector is provided, including cooler and knockout drum, the knockout drum is higher than the cooler setting, the export of cooler and the entry linkage of knockout drum, and the sample connection and the discharge port department of knockout drum are equipped with the ooff valve respectively, the external normal atmospheric temperature water of coolant entry of cooler, the entry of cooler still are connected with the connecting pipe, and the connecting pipe is used for connecting the sample connection of examining test set.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: equipment such as heat exchangers can be inspected during plant production to ultimately identify leaks by cool separation accumulation. The device is suitable for the online detection of chemical gas-water, oil-gas and other heat exchange equipment.
Preferably, the outlet of the cooling medium of the cooler is externally connected with a discharge pipe or a circulating pipeline.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in figure 1, an online leak detector, including cooler 1 and knockout drum 2, knockout drum 2 is higher than the cooler setting, the preferred, the bottom of knockout drum 2 is not less than the top setting of cold gas ware 1, the export of cooler 1 and the entry linkage of knockout drum 2, the sample connection and the discharge outlet department of knockout drum 2 are equipped with the ooff valve respectively, the external normal atmospheric temperature water of coolant entry of cooler, the entry of cooler still is connected with the connecting pipe, the connecting pipe is used for connecting the sample connection of examining the check out test set. Wherein, the cooling medium outlet of the cooler 1 is externally connected with a discharge pipe or a circulating pipeline.
Specifically, the online leak detector is connected to a collection point of equipment to be detected, such as a heat exchanger or a pipeline, the medium takes steam as an example, the sampling medium enters a separation tank after passing through a cooler, condensate is slowly filled in the separation tank, air in the equipment is exhausted from a discharge port and a sampling port, a valve of the sampling port is closed after water is filled in the whole equipment, a valve of the discharge port is reserved, the accumulation detection is carried out for a period of time, if non-condensable gas can be accumulated at the sampling port, and whether the leakage phenomenon exists in the heat exchanger corresponding to the detection point can be judged from the sampling port. Wherein for a multi-component gas medium, a sample is assayed at the sample port, for a single component gas, it is detected by the exhaust gas, and for a liquid medium, it is assayed by the sample.
The utility model discloses can inspect equipment such as heat exchanger during device production, finally confirm through the cooling separation accumulation and leak. The device is suitable for the online detection of chemical gas-water, oil-gas and other heat exchange equipment. That is, equipment such as a heat exchanger in an on-line production device can be detected, and the leakage condition can be determined by collecting non-condensable gas or oil phase substances. The cost and the tedious operation of equipment inspection after parking are reduced, the leakage target or range can be directly determined, each or a plurality of heat exchangers and pipelines can be checked one by one on line, the leakage equipment is finally confirmed, and the loss of production stoppage, the detection time and the cost are reduced.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
