Description

Technical Field

[0001] The utility model relates to the technical field related to the production industry, in particular to a protection device for a temperature measuring probe in a high-ash and high-salt smoke system. Background Technique

[0002] With the continuous increase in the number of hazardous waste disposal industries and power generation industries in China, the utilization rate of various analytical and testing instruments is also increasing continuously. Various instruments have a certain economic value. If these instruments are not used correctly, it will not only cause great harm to the process, but also cause great economic waste.

[0003] However, the existing protection device for the measurement chamber in the smoke system does not have a filtering device at the boiler outlet. The incompletely burned medium liquefies in different temperature conditions, easily clogs and damages the measurement chamber, causing the sensor to short-circuit. Since the use environment is in a negative pressure state, general measurement devices cannot normally measure the gas content in the furnace under high-ash and high-salt conditions and cannot automatically clean the ash accumulation normally, resulting in the clogging and damage of the measurement chamber, seriously affecting the long-term stable operation, production efficiency and production continuity of production equipment. Content of the Utility Model

[0004] In order to solve the problem that in the prior art, some incompletely burned gases in the waste heat boiler section will be converted into liquids during use, and this part of the liquid will cause the sensor to short-circuit, making the measurement data meaningless. Some manufacturers either replace the sensor or repair and scrap it. For this reason, the utility model provides a protection device for a temperature measuring probe in a high-ash and high-salt smoke system, which can protect the sensor and thus reduce the production cost.

[0005] To achieve the above object, the utility model provides the following technical solution: A protection device for a temperature measuring probe in a high-ash and high-salt smoke system, including a housing and an automatic control system.

An air storage tank is fixedly connected to the outer wall of the housing. A heating device is installed on the inner wall of the housing.

[0006] Preferably, the honeycomb ceramic filter is installed inside the intake passage so that when the flue gas enters the ventilation pipe, the honeycomb ceramic filter can filter it.

[0007] Preferably, the tubular ceramic filter is installed inside the intake passage so that when the flue gas enters the latter section of the ventilation pipe, the tubular ceramic filter can perform secondary filtration on it.

[0008] Preferably, the heating thermocouple and the emergency stop sensor are installed inside the heating chamber so that when the temperature reaches the upper and lower limit alarm values, the relevant equipment is stopped emergently, the heating chamber no longer performs automatic temperature compensation, and various equipment such as the corresponding intake valve and the dust collector rapping are closed.

[0009] Preferably, the gas storage tank is connected to the first rapping device and the flue gas and compressed air mixing suction device respectively through gas pipelines so that the gas storage tank can compress the gas.

[0010] Preferably, the mixing ratio of the flue gas and the compressed air inside the flue gas and compressed air mixing suction device is: 1:4 - 5.

[0011] The difference from the prior art lies in that the beneficial effect of this application is:

[0012] The protection device for the temperature measurement probe in the high-ash and high-salt smoke system can burn the flue gas through the cooperation of the heating thermocouple and the heating chamber, so as to perform combustion oxidation treatment on the impurities in the flue gas. Through the setting of the maintenance door drain valve, the medium that has not been fully burned, the liquid generated after the gas is liquefied at different temperatures, will be discharged through the maintenance door drain valve, improving the overall usability of the device.

[0024] Embodiment 1. Please refer to Figure 1 - Figure 3 , as shown in the figure, a protection device for a temperature measurement probe in a high-ash and high-salt smoke system includes a housing 1600 and an automatic control system 1300. An intake electric valve 100 is fixedly connected to the outer wall of the housing 1600. A heating chamber 1700 is provided inside the housing 1600. An intake passage 1800 is provided inside the housing 1600. A honeycomb ceramic filter 200 is fixedly connected to the inner wall of the intake passage 1800. A first vibrator 300 is installed on the outer wall of the housing 1600. A tubular ceramic filter 400 is fixedly connected to the inner wall of the intake passage 1800. A heating thermocouple 500 is installed on the inner wall of the heating chamber 1700. An emergency stop sensor 600 is installed on the inner wall of the heating chamber 1700. An inspection door drain valve 700 is installed on the outer wall of the housing 1600. A back purge valve 800 is installed on the inner wall of the heating chamber 1700. The operating frequency of the back purge valve 800 is controlled to open once every 30 seconds. An oxygen zirconia analyzer 900 is installed on the outer wall of the housing 1600. A flue gas and compressed air mixed suction device 1500 is installed on the outer wall of the housing 1600. A second vibrator 1100 is installed on the outer wall of the flue gas and compressed air mixed suction device 1500. A negative pressure injector 1000 is installed on the outer wall of the second vibrator 1100. A gas storage tank 1200 is fixedly connected to the outer wall of the housing 1600. A heating device 1400 is installed on the inner wall of the housing 1600.

[0025] In use, by adjusting the intake electric valve 100, the flue gas can stably enter the interior of the intake passage 1800. When the flue gas passes through the honeycomb ceramic filter 200 and the tubular ceramic filter 400, the honeycomb ceramic filter 200 and the tubular ceramic filter 400 can filter the flue gas, thereby filtering out the impurities in the flue gas. And through the first vibrator 300, it can prevent the impurities in the flue gas from accumulating in the intake passage 1800 and causing blockage of the intake passage 1800. When the flue gas enters the interior of the heating chamber 1700 through the intake passage 1800, the heating thermocouple 500 will heat the heating chamber 1700 and keep the internal temperature of the heating chamber 1700 within the range of 550 - 650 °C, so that the flue gas is incinerated inside the heating chamber 1700, thereby burning and oxidizing the impurities in the flue gas. Some media that have not been fully burned and the liquid generated after the gas is liquefied at different temperatures will be discharged through the inspection door drain valve 700. And the emergency stop sensor 600 can detect the data changes inside the heating chamber 1700 in real time and transmit the data to the automatic control system 1300. When the temperature inside the heating chamber 1700 is abnormal, the automatic control system 1300 will forcibly close the heating thermocouple 500 and the intake electric valve 100 to stop the device from continuing to work. And the zirconia analyzer 900 can detect whether the flue gas meets the emission standards. When the flue gas does not meet the emission standards, the back purge valve 800 will be activated, and the dust particles in the flue gas will be blown back into the interior of the heating chamber 1700 for continued incineration under high-pressure purging. After the flue gas meets the emission standards, it will enter the interior of the flue gas and compressed air mixing suction device 1500, mix with the air inside the air storage tank 1200 and then be ejected through the negative pressure injector 1000, avoiding the phenomenon that the probe is prone to ash accumulation or coking, resulting in inaccurate data, and improving the overall usability of the device.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
