The utility model provides a metering system of desulfurizing tower, including desulfurizing tower, quartz capsule level gauge and flushing pipe, wherein, the desulfurizing tower is constructed and is used for gaseous desulfurization to form the ammonium sulfate thick liquid at desulfurizing tower bottom, quartz capsule level gauge is connected with the bottom of desulfurizing tower through the feed channel, and quartz capsule level gauge is used for measuring the liquid level of desulfurizing tower, and flushing pipe intercommunication is located the position between desulfurizing tower and the quartz capsule level gauge on the feed channel, and is constructed and is used for importing the flushing fluid to the feed channel, and at least part flushing fluid is configured to flow to the direction of quartz capsule level gauge.
Therefore, as the flushing pipeline is communicated with the feeding channel at a position between the desulfurizing tower and the quartz tube liquid level meter and is configured to input flushing liquid into the feeding channel, at least part of the flushing liquid is configured to flow towards the quartz tube liquid level meter, the blocking phenomenon is effectively avoided, and the quartz tube liquid level meter has strong corrosion resistance and has the condition of long-period running.
For ease of understanding, the specific structure of the metering system of the desulfurizing tower of the present disclosure and its operation will be described in detail with reference to fig. 1 to 3 in conjunction with an embodiment.
As shown in fig. 1 and 2, the present disclosure provides a metering system of a desulfurizing tower, including a desulfurizing tower 1, a quartz tube level gauge 2 and a flushing pipe 4, wherein the quartz tube level gauge 2 is configured to extend in a height direction, the bottom of the quartz tube level gauge 2, a feed channel 3, the desulfurizing tower 1 constitutes a U-shaped structure, an exhaust pipe 5 is provided at the top end of the quartz tube level gauge 2, and the exhaust pipe 5 is configured to communicate with an inner cavity of the quartz tube level gauge 2.
Specifically, the quartz tube level gauge 2 has an inner cavity, and graduations may be provided on a sidewall of the quartz tube level gauge 2. The bottom of the quartz tube liquid level meter 2 is connected with the bottom of the desulfurizing tower 1 through a feeding channel 3 to form a passage. This allows the ammonium sulfate slurry at the bottom of the desulfurizing tower 1 to directly enter the quartz tube level gauge 2 through the feed channel 3 under the action of the pressure difference. Compared with the traditional magnetic flap level meter, the ammonium sulfate slurry directly enters the quartz tube level meter 2 through the feeding channel 3 and rises to a preset height in the quartz tube level meter 2 under the action of pressure difference, so that the liquid level of the ammonium sulfate slurry at the bottom of the desulfurizing tower 1 can be directly read, and the measuring precision is ensured. In addition, the blocking of the quartz tube liquid level meter 2 by the ammonium sulfate slurry can be avoided to a certain extent, so that the measurement accuracy is affected.
In the embodiment of the disclosure, the top end of the quartz tube liquid level meter 2 is provided with the exhaust pipe 5, the bottom of the quartz tube liquid level meter 2, the feeding channel 3 and the desulfurizing tower 1 form a U-shaped structure, so that the internal air pressure of the quartz tube liquid level meter 2 is consistent with the air pressure at the bottom of the desulfurizing tower 1, and the liquid level height of the quartz tube liquid level meter 2 is consistent with the liquid level height at the bottom of the desulfurizing tower 1. In addition, a feed valve 14 may be provided between the feed passage 3 and the bottom of the desulfurizing tower 1, the feed valve 14 being used to control the input of the medium in the desulfurizing tower 1 to the feed passage 3. When the metering system of the desulfurizing tower needs to be overhauled, the feed valve 14 is closed for overhauling.
Based on this, in the operation process of the metering system of the desulfurizing tower of the present disclosure, when the liquid level at the bottom of the desulfurizing tower 1 changes, the liquid level of the quartz tube liquid level gauge 2 also changes synchronously, so that the liquid level of the quartz tube liquid level gauge 2 and the liquid level at the bottom of the desulfurizing tower 1 always keep consistent. The quartz tube liquid level meter 2, the feeding channel 3 and the bottom of the desulfurizing tower 1 form a U-shaped structure, and the liquid level height of the bottom of the desulfurizing tower 1 is measured in real time by applying the principle of a communicating vessel, so that the measuring result is more accurate.
Further, considering that the medium in the desulfurizing tower 1 and the liquid level gauge is ammonium sulfate slurry, which is corrosive and easily acidifies soil, as shown in fig. 3, in one embodiment of the present disclosure, the top of the quartz tube liquid level gauge 2 is provided with an upper flange 6, and the exhaust pipe 5 is connected with the upper flange 6 through an upper flange cover 7. A tetrafluoro pad 8 is provided between the upper flange cover 7 and the upper flange 6, the tetrafluoro pad 8 being configured to prevent leakage of liquid in the quartz tube level gauge 2.
Specifically, the top end of the quartz tube liquid level meter 2 is provided with an upper flange 6 and an upper flange cover 7, and a connection manner between the upper flange 6 and the upper flange cover 7 can be set according to actual needs, which is not limited herein, and in this embodiment, the connection manner between the upper flange 6 and the upper flange cover 7 is a bolt connection. The exhaust pipe 5 is connected with the upper flange plate 6 through the upper flange cover 7 and is communicated with the inside of the quartz tube liquid level meter 2. The tetrafluoro pad 8 is arranged on the outer side of the quartz tube liquid level meter 2 part between the upper flange cover 7 and the upper flange plate 6, and the tetrafluoro pad 8 also has the characteristic of corrosion resistance, so the arrangement of the tetrafluoro pad 8 can not only prevent the ammonium sulfate slurry from overflowing from the quartz tube liquid level meter 2 and pollute the external environment, but also prevent the corrosive ammonium sulfate slurry from damaging other parts.
Further, in order to avoid the long-time operation of the washing water pipe, waste of water resources is caused, and a large amount of water enters the feed channel 3, which may affect the desulfurization process. Thus, as shown in fig. 2, in one embodiment of the present disclosure, a rinse valve 9 is provided on the rinse pipe 4, the rinse valve 9 being configured for controlling the input of rinse liquid. The frequency of feeding flushing liquid into the feed channel 3 was once every 8 hours.
Specifically, the flushing valve 9 is arranged at a position convenient to operate, and the flushing valve 9 in the embodiment has the functions of remote operation and on-site operation, so that the input of flushing liquid can be controlled remotely and on-site. In addition, the frequency of feeding the flushing liquid into the feed passage 3 may be set according to actual needs, and is not limited in any way. In this example, the frequency of feeding the rinse liquid into the feed channel 3 was set to rinse every 8 hours in combination with the process flow of the entire desulfurization process.
Based on this, during the operation of the metering system of the desulfurizing tower of the present disclosure, the operator controls the opening or closing of the flushing valve 9 by remote or on-site operation, thereby controlling the input of the flushing liquid into the feed passage 3. The automatic flushing frequency of the flushing valve 9 is usually set to be one flushing time every 8 hours, the flushing pipeline 4 is connected with a flushing pump, the flushing pump pumps flushing liquid into the flushing pipeline 4 when the flushing valve 9 is in an opened state, flushing liquid enters the flushing pipeline 4 from top to bottom under the pressure of 0.4Mpa, after the flushing liquid flows to the bottom of the flushing pipeline 4, a part of flushing liquid flows into the direction of the quartz tube liquid level meter 2 through the feeding channel 3, and another part of flushing liquid flows into the bottom direction of the desulfurizing tower 1 through the feeding channel 3, and the flushing liquid can regularly flush ammonium sulfate slurry at the bottom of the quartz tube liquid level meter 2 and the desulfurizing tower 1, so that the blockage of the quartz tube liquid level meter 2 is avoided, and the accuracy of the measuring result of the quartz tube liquid level meter 2 is ensured. In addition, the feeding channel 3 can be widened, and the widened feeding channel 3 can reduce the blocking probability of ammonium sulfate slurry to a certain extent.
Further, considering that the quartz tube liquid level meter 2 can only observe the measurement result in situ, when the liquid level needs to be monitored, workers are required to go to the site to observe, which results in high time consumption and high labor cost. Thus, as shown in fig. 2, in one embodiment of the present disclosure, the metering system of the desulfurizing tower further comprises: the remote liquid level gauge 10, the remote liquid level gauge 10 is connected with the bottom of the desulfurizing tower 1 through the feeding channel 3, and the remote liquid level gauge 10 is used for measuring the liquid level height of the desulfurizing tower 1.
Specifically, the remote liquid level meter 10 is connected with the bottom of the desulfurizing tower 1 through the feeding channel 3, the remote liquid level meter 10 comprises a high-pressure end, a low-pressure end and a differential pressure transmitter, wherein the differential pressure transmitter is positioned between the high-pressure end and the low-pressure end, when the liquid level at the bottom of the desulfurizing tower 1 changes, the differential pressure detected by the differential pressure transmitter also changes along with the change of the liquid level, and the change of the liquid level and the change of the differential pressure have a linear relationship, so that the liquid level height of the desulfurizing tower 1 can be measured. In the process of the metering result work of the present disclosure, the staff can perform auxiliary monitoring on the liquid level of the desulfurizing tower 1 through the remote liquid level meter 10, and the labor and time cost can be further saved.
Further, under the condition that the desulfurizing tower 1 operates for a long time, the medium in the desulfurizing tower 1 is easy to form deposition near the remote liquid level meter 10 and the mounting hole after long-time chemical reaction, and is attached to the surface of the remote liquid level meter, so that the sensitivity of the remote liquid level meter 10 is reduced, and the measurement result is inaccurate. Thus, in one embodiment of the present disclosure, the remote fluid level gauge 10 is configured to be calibrated from data obtained by the quartz tube fluid level gauge 2.
Specifically, the staff member periodically calibrates the measurement result of the remote liquid level meter 10, and when the measurement result of the remote liquid level meter 10 is inconsistent with the measurement result of the quartz tube liquid level meter 2, the staff member calibrates the measurement value of the remote liquid level meter 10 to be consistent with the measurement value of the quartz tube liquid level meter 2. The accuracy of the calibration result can be improved by calibrating the remote liquid level meter 10 through the quartz tube liquid level meter 2.
Further, considering that the metering system of the desulfurizing tower is arranged outdoors, the quartz tube liquid level meter 2 may be damaged due to the influence of external factors such as sand wind and the like. Thus, as shown in fig. 3, in one embodiment of the present disclosure, the outer wall of the quartz tube level gauge 2 is provided with a protective tube 11, the protective tube 11 being configured for protecting the quartz tube level gauge 2.
