Description

Technical Field

[0001] The utility model relates to the technical field of environmental analysis and measurement, in particular to a flue gas measurement mechanism and a sampling pipeline cleaning device in an environmental protection equipment analyzer. Background Art

[0002] As the environment becomes increasingly harsh, people's awareness of environmental protection is gradually increasing. In real life, flue gas pollution is an important aspect of pollution to people's living environment. Thermal power plants, industrial boilers, steel smelting and other scenes are the main places for flue gas emissions. Flue gas measurement and analyzers are used to measure the concentration and total amount of gaseous pollutants and particulate matter emitted by air pollution sources and provide accurate monitoring data for environmental protection departments.

[0003] Existing flue gas measurement and analyzers collect flue gas by using a sampling probe, remove waste water through the condensation effect of a condenser, and analyze the filtered sample gas. However, for conventional condensation and water removal methods, the loss of SO2 is very large, which will affect the measurement results. In addition, when sampling flue gas, the temperature inside the sampling tube may be too high, which may easily cause equipment damage. Due to long-term use of the entire device, pollutants may be deposited in the sampling tube. If they are not cleaned in time, the service life of the equipment may be reduced and maintenance costs may be increased. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the above-mentioned problems that the large loss of SO2 affects the measurement results and the high temperature inside the sampling tube easily causes damage to the equipment, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a flue gas measuring mechanism.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a flue gas measuring mechanism, comprising a accommodating component, including a mounting component, a sampling component arranged on the mounting component, and a titration component arranged on the mounting component; and a protection component, comprising a driving component arranged on the mounting component, a closing component arranged on the sampling component, and an opening component arranged on the sampling component.

[0008] As a preferred solution of the smoke measuring mechanism of the utility model, the mounting member includes a box body, a placement plate arranged on one side of the box body, and a partition plate arranged inside the box body.

[0009] As a preferred solution of the flue gas measurement mechanism of the utility model, the sampling component includes a condenser arranged on the partition, a sampling tube arranged on the box body, a sampling probe arranged at the end of the sampling tube, and a delivery pipe arranged on the condenser.

[0011] As a preferred solution of the smoke measuring mechanism of the utility model, the driving member includes a motor arranged on the box body, a threaded rod arranged on the output end of the motor, and a vertical plate arranged on the box body.

[0012] As a preferred solution of the smoke measuring mechanism of the utility model, the closing member includes a circular rod arranged on the sampling tube, a closing plate arranged on the circular rod, a fan-shaped block arranged at the end of the circular rod, a slide groove opened on the fan-shaped block, and a moving block arranged in the slide groove.

[0013] As a preferred solution of the smoke measuring mechanism of the utility model, the opening member includes a guide tube arranged on the sampling tube, a gear arranged on the threaded rod, a rack arranged on the guide tube, and a cover plate arranged on the guide tube.

[0014] The beneficial effects of the flue gas measuring mechanism described in the utility model are as follows: the utility model adopts a peristaltic pump to perform phosphoric acid titration at the front end of the condenser, and phosphoric acid is dripped into the condenser pipeline. Since the solution is highly acidic, it is beneficial to improve the SO2 measurement accuracy of the analyzer. By setting a closing piece, when the internal temperature of the sampling tube is too high, the sampling tube is blocked, and by opening the guide tube, when the main sampling path is closed, the flue gas can bypass the device system and be directly discharged into the atmosphere through the guide tube to prevent damage to the device.

[0015] In actual use, there is still a problem that the sediment inside the sampling tube is not cleaned in time, which may reduce the service life of the equipment and increase maintenance costs.

[0016] In order to solve the above technical problems, the utility model also provides the following technical solutions: a sampling pipe cleaning device in an environmental protection equipment analyzer, including the above flue gas measuring mechanism, and also including a cleaning component, including a conveying part arranged on the mounting part, and an emission part arranged in the mounting part.

[0033] Specifically, the mounting member 101 includes a box body 101a, a placement plate 101b fixedly connected to one side of the box body 101a, and a partition 101c fixedly connected inside the box body 101a. The placement plate 101b serves to receive and place the sample, and the partition 101c is used to place the sampling member 102 and divide the box body 101a into a wastewater tank area.

[0034] Furthermore, the sampling member 102 includes a condenser 102a fixedly connected to the top of the partition 101c, a sampling tube 102b fixedly connected to the box 101a, a sampling probe 102c rotatably connected to the end of the sampling tube 102b, and a delivery tube 102d fixedly connected to the condenser 102a. The condenser 102a condenses the collected sample gas, and one end of the sampling tube 102b away from the condenser 102a is fixedly connected to the box 101a to provide a path for the sample gas. The sampling tube 102b is L-shaped, and the sampling probe 102c is fixedly connected to the sampling tube 102b. An air inlet is provided at the end of the sampling probe 102c, and a micro-sampling pump is arranged inside. When the sampling pump is started, the sample gas is sucked, and the sample gas passes through the air inlet of the sampling probe 102c, so that the sample gas passes through the sampling probe 1 02c enters the sampling tube 102b, the sampling probe 102c can be disassembled and assembled, the delivery tube 102d is used to transport the condensed sample gas into the analyzer body 102e fixedly connected at the end of the delivery tube 102d, the analyzer body 102e is fixedly connected to the box 101a, and a display screen is provided on the side of the analyzer body 102e outside the box.

[0036] Operation process: When the sampling pump in the sampling probe 102c is started, the flue gas is sucked by the sampling probe 102c, passes through the sampling tube 102b, and enters the condenser 102a. Due to the escape of ammonia during the ammonia spraying process, there is NH3 in the flue gas, and NH3 will become NH4+ (ammonium ion) and OH- (hydroxyl ion) in liquid water. The H2O produced by the reaction of OH- and H+ will increase the solubility of SO2. For the conventional condensation dehydration method, the loss of SO2 is very large. When the peristaltic pump 103b is working, the peristaltic pump 103b will The rate of 3b is 1.0r / min. Phosphoric acid is added before the condenser 102a. The phosphoric acid concentration is 8%, which is equivalent to containing a large amount of H+ in the condenser 102a. The addition of a large amount of H+ can inhibit the dissolution of SO2 on the one hand, and react with OH- in the solution on the other hand to produce water to absorb NH3, thereby removing or converting ammonia, and then enters the analyzer body 102e through the delivery pipe 102d for analysis, making the determination of SO2 more accurate. The condensed wastewater is discharged into the wastewater tank divided by the partition 101c.
