Description

Technical Field

[0001] The utility model relates to the technical field of dust meters, and more specifically, the utility model relates to a purging and measuring device for a dust meter at the outlet of a dust collector. Background Art

[0002] The purging and transformation scheme of the dust meter lens is based on the principle of measuring the smoke and dust concentration by the back-scattering method of laser. During the measurement process, clean gas is required as the purging gas source to prevent dust in the flue gas from adhering to the lens surface and affecting the measurement. However, it is very difficult to obtain truly clean purging gas in actual operation. Usually, there is water vapor and oil stain in the compressed air, which will affect the measurement of the dust meter.

[0003] The CEMS compressed air comes from the gas used in the desulfurization gas storage tank. The moisture content of the compressed air is relatively large all year round, and there is more oil stain in the gas. The CEMS dust measurement instrument at the desulfurization outlet is a PM-100 infrared single-lens reflex back-scattering type, and its purging gas is connected to the compressed air by a φ8 hose for continuous purging for 24 hours. Therefore, when the quality of the compressed air is not good, it is easy to attach oil and water vapor to the lens surface of the dust meter during purging, seriously affecting the dust measurement.

[0004] Therefore, a purging and measuring device for a dust meter at the outlet of a dust collector is proposed. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a purging and measuring device for a dust meter at the outlet of a dust collector to solve the problems raised in the above background art.

[0006] To achieve the above object, the utility model provides the following technical solution: A purging and measuring device for a dust meter at the outlet of a dust collector, including a purging cylinder, one end of the purging cylinder is provided with a blowing port, an exhaust pipe connected to the blowing port is arranged inside the purging cylinder, a filtering component is sleeved on the exhaust pipe, the purging cylinder is connected with a connecting column, a hoop is arranged at the connection between the purging cylinder and the connecting column, an extrusion mechanism slidably matched with the exhaust pipe is installed on the connecting column, an air inlet pipe is arranged outside the top end of the connecting column, and a guide pipe communicated with the air inlet pipe is arranged inside the top end of the connecting column.

[0007] By connecting a blower to the intake pipe, when the blower is operating, air is taken in from the intake pipe, guided by the guide pipe into the filter assembly, filtered, and then discharged from the exhaust pipe. During the discharge process, the structural design of the exhaust pipe and the air blowing port can increase the exhaust flow rate, thereby improving the blowing effect and the blowing range. In this way, when the gas blown out from the air blowing port blows on the lens, the dust on the lens can be cleaned by the clean air flow, thus avoiding contaminating the lens. During long-term use, after the solenoid valve is opened, the two electric push rods extend synchronously, causing the pressing plate to squeeze the filter element along the exhaust pipe, thereby compressing the filter element and discharging the liquid impurities adsorbed inside the filter element, enabling self-cleaning, improving the filtering and adsorption effects of the filter element, and discharging the liquid impurities mixed in the filter element from the sewage discharge pipe, thereby improving the filtering effect of the filter assembly, being able to clean itself, and improving the convenience of use.

[0008] Preferably, the air blowing port has a conical groove structure and is coaxially arranged with the exhaust pipe.

[0009] Preferably, the squeezing mechanism includes two electric push rods, and the two electric push rods are symmetrically installed on the connecting column;

[0010] A pressing plate, which is connected to the output ends of the two electric push rods and is slidably connected to the exhaust pipe.

[0011] Preferably, a plurality of air permeable holes are formed in the pressing plate, and the guide pipe is slidably connected to one of the air permeable holes.

[0012] Preferably, the filter assembly includes a filter element, the filter element is made of sponge material, and the filter element is sleeved on the exhaust pipe;

[0013] A shaft hole, which is formed in the middle of the filter element and is coaxially arranged with the exhaust pipe;

[0014] A gas guiding groove, which is formed in the filter element, and one end of the guide pipe is inserted into the gas guiding groove.

[0015] Preferably, the purging cylinder is connected with a sewage discharge pipe, and a solenoid valve is installed on the sewage discharge pipe.

[0016] The technical effects and advantages of the present utility model:

[0017] 1. Through the settings of the filter element, the gas guiding groove, the guide pipe and the exhaust pipe, compared with the prior art, when the gas introduced from the outside enters the purging cylinder through the guide pipe, it can first pass through the filter element for filtration and then be discharged from the exhaust pipe, thereby improving the cleanliness of the gas blown out from the air blowing port and avoiding contaminating the lens;

[0018] 2. The provision of the electric push rod, pressure plate, sewage pipe and solenoid valve, compared with the prior art, enables the pressure plate to squeeze the filter element along the exhaust pipe by the synchronous elongation of the two electric push rods, thereby compressing the filter element and allowing the liquid debris adsorbed inside the filter element to be discharged through the sewage pipe, thus improving the filtering effect of the filtering component, being able to clean itself and enhancing the convenience of use.

[0019] 3. The structural design of the air blowing port and the exhaust pipe, compared with the prior art, according to the Laval principle, by setting the inner diameter of the exhaust pipe to be smaller than that of the air blowing port, enables the gas flowing out of the exhaust pipe to increase in speed, thereby enhancing the air blowing intensity. At the same time, the air blowing port has a conical structure, which can increase the air blowing range and thus improve the cleaning effect of the dust on the lens surface.

The blowing port 4 is in a conical groove structure and is coaxially arranged with the exhaust pipe 8. The purging cylinder 1 is connected with a sewage discharge pipe 5. A solenoid valve is installed on the sewage discharge pipe 5.

[0028] During specific implementation, by connecting a blower to the air inlet pipe 7, when the blower is operating, air enters from the air inlet pipe 7, and after passing through the filtering component 9 under the guidance of the guide pipe 10 and being filtered, it is discharged from the exhaust pipe 8. During the discharging process, due to the structural design of the exhaust pipe 8 and the blowing port 4, the exhaust flow rate can be increased, thereby improving the blowing effect and the blowing range. In this way, when the gas blown out from the blowing port 4 blows on the lens, the dust on the lens can be cleaned by the clean air flow, thus avoiding polluting the lens. During long-term use, the extrusion mechanism 6 can be operated, and the solenoid valve is opened in cooperation, so that the extrusion mechanism 6 squeezes the filtering component 9, causing the filtering component 9 to be compressed, and the liquid impurities mixed in the filtering component 9 are discharged from the sewage discharge pipe 5, thereby improving the filtering effect of the filtering component 9, being able to clean itself, and improving the convenience of use.

[0032] During specific implementation, by the two electric push rods 601 extending synchronously, the pressing plate 602 is pressed along the exhaust pipe 8 towards the filter element 901, so that the filter element 901 is compressed, and the liquid impurities adsorbed inside the filter element 901 are discharged, thus being able to perform self-cleaning and improving the filtering and adsorption effects of the filter element 901.
