Detailed Description
The core of the invention is to provide a method for detecting the working state of the exhaust gas purification device and related components thereof, which not only can detect whether the exhaust gas purification device has faults or problems, but also can reflect the service life of the exhaust gas purification device through the working state.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for detecting an operating state of an exhaust gas purifying apparatus according to the present application, including:
s1: acquiring working condition parameters of the waste gas purification device, wherein the working condition parameters comprise one or more of air inlet waste gas concentration, air outlet waste gas concentration, air inlet air speed, material temperature of an adsorption layer in the waste gas purification device, air pressure difference of the adsorption layer, humidity of the adsorption layer and power consumption of the waste gas purification device;
the waste gas purification device is a purification device specially used for purifying the VOCs waste gas in the air, the working principle of the purification device is generally similar to that of a water filter, and the VOCs waste gas is usually purified by an adsorption method, a photolysis method, a low-temperature plasma method or a mixed method of the methods, and the methods all need to use an adsorption layer made of certain adsorption materials (such as activated carbon or activated alumina and other materials) to filter the waste gas in the air.
Because the total capacity that adsorption material itself can adsorb is limited, therefore adsorption material is equivalent to the consumer, along with the increase of live time, adsorption efficiency of adsorption material can decline gradually until unable absorption, consequently need in time change the adsorption material in exhaust gas purification device's the adsorbed layer. The prior art considers that the exhaust gas purification device has a simple structure and a single function, so that the exhaust gas purification device is not detected, only the approximate duration of normal use of the adsorption material in practical application is determined according to the adsorption capacity of the adsorption material, the duration is taken as the service life of the adsorption material, in practical application, a user is reminded to replace the adsorption material when the practical use duration of the adsorption material is close to the service life, it is seen that the service life of the adsorption material is influenced by parameters such as the concentration of exhaust gas and the temperature in practical application, and if the adsorption material adsorbs in the environment with high concentration of exhaust gas for a long time, the real service life of the adsorption material is inevitably smaller than the specified service life. Based on this, in order to determine the actual service life of the exhaust gas purification device, the prior art considers that the exhaust gas concentration in the air discharged by the exhaust gas purification device is a standard for checking the purification capacity of the exhaust gas purification device, and therefore, the exhaust gas concentration at the air outlet of the exhaust gas purification device can also be detected, but the purification capacity of the exhaust gas purification device cannot be accurately obtained only by detecting the exhaust gas concentration at the air outlet without considering factors such as air leakage of a pipeline, stop of a fan, and overlarge cavity of an adsorption material of the exhaust gas purification device. For example, if the air inlet pipeline of the exhaust gas purification device leaks air, the exhaust gas will leak to the outside again after being sucked into the air inlet by the fan, which is equivalent to that no exhaust gas purification is performed, and the exhaust gas concentration detected at the air outlet is not high due to no air circulation, so it is visible that only the exhaust gas concentration at the air outlet can be determined to be not high, but the condition that the exhaust gas purification device leaks air and cannot work normally cannot be known.
In order to solve the above technical problems, in the present application, any one of the exhaust gas concentration at the air inlet, the exhaust gas concentration at the air outlet, the air speed at the air inlet, the material temperature of the adsorption layer in the exhaust gas purification device, the air pressure difference of the adsorption layer, the humidity of the adsorption layer, and the power consumption of the exhaust gas purification device may be detected as a parameter for determining whether the exhaust gas purification device has a problem, wherein in addition to determining the purification capability of the exhaust gas purification device according to the exhaust gas concentration at the air outlet, the exhaust gas concentration at the air inlet is detected in consideration that the exhaust gas purification device usually operates in an environment where exhaust gas needs to be purified, so that the exhaust gas concentration at the air inlet is usually high, and in order to detect whether the exhaust gas purification device can normally suck in exhaust gas, the exhaust gas concentration at the air inlet needs to be detected; the air speed of the air inlet is equivalent to further detecting whether the waste gas purification device can normally suck waste gas, the waste gas purification device can usually purify a large amount of air at the same time, when the rotating speed of the fan is small, although a certain amount of waste gas can be sucked, the purification efficiency of the waste gas purification device is low due to the fact that the sucked amount is too small, and the situation that the waste gas purification device does not work can be approximately judged; the material temperature of the adsorption layer is that the adsorption capacity of materials such as activated carbon, activated alumina and the like is related to the temperature of the adsorption layer, and the adsorption capacity of the adsorption material is reduced when the adsorption material is hot; for the air pressure difference of the adsorption layer, because the adsorption material needs to contact the air containing the waste gas, the air not only contains various harmful gases, but also contains various harmful solids, the adsorption material contacts the air for a long time, the harmful substances in the air can continuously corrode the adsorption material to generate a cavity, and the generated cavity can increase the air circulation in the adsorption layer and reduce the pressure difference, so that the waste gas is discharged without being purified in time; for the humidity of the adsorption layer, when the humidity is higher, it is indicated that the water drops in the gas are more, the water drops not only carry harmful gas molecules and harmful solid particles, when the water drops enter the adsorption layer, some channels of the adsorption layer are easily blocked, so that the total adsorption area of the adsorption layer is reduced, and the purification effect of the adsorption layer is further influenced; to exhaust gas purification device's power consumption, a plurality of power consumptions through detecting different time points, can clearly learn exhaust gas purification device's actual power consumption between two adjacent check-out time points, compare with exhaust gas purification device's theoretical power consumption between two adjacent check-out time points according to this actual power consumption, can learn whether exhaust gas purification device's operation is normal, it is further, can also determine exhaust gas purification device's operating duration and user's power consumption cost according to the power consumption, so that in time rest and remind the power consumption cost of user's its expense behind exhaust gas purification device operating duration overlength. Therefore, when the working condition parameters are obtained, one or more combinations of the air inlet waste gas concentration, the air outlet waste gas concentration, the air inlet air speed, the material temperature of the adsorption layer in the waste gas purification device, the air pressure difference of the adsorption layer, the humidity of the adsorption layer and the power consumption of the waste gas purification device need to be detected according to actual scenes and requirements.
S2: and determining the working state of the exhaust gas purification device according to the working condition parameters, wherein the working state comprises a normal state and a fault state.
After the operating condition parameters are determined, the operating state of the exhaust gas purification device can be determined according to the specific operating condition parameters, and specific parameter ranges can be set for the operating condition parameters in advance according to actual conditions to serve as normal ranges of the operating condition parameters. In practical application, for example, when the operating condition parameter includes the exhaust gas concentration at the air inlet, if it is detected that the exhaust gas concentration at the air inlet is too low, it indicates that the exhaust gas purification device does not suck the exhaust gas, which may be caused by the conditions of the air inlet fan of the exhaust gas purification device, the fan blade damage or the air inlet blockage, and the like, so that the operating state of the exhaust gas purification device can be determined to be the fault state when the exhaust gas concentration at the air inlet is too low.
In summary, firstly, the operating condition parameters of the exhaust gas purification device are obtained, and the operating state of the exhaust gas purification device is determined according to the operating condition parameters, wherein the operating condition parameters include one or more combinations of the air inlet exhaust gas concentration, the air outlet exhaust gas concentration, the air inlet air speed, the material temperature of the adsorption layer in the exhaust gas purification device, the air pressure difference of the adsorption layer, the humidity of the adsorption layer and the power consumption of the exhaust gas purification device, and the operating state includes a normal state and a fault state. Through the operating condition who detects exhaust gas purification device, not only can detect exhaust gas purification device whether have trouble or problem, but also can reflect exhaust gas purification device's life through operating condition.
On the basis of the above-described embodiment:
as a preferred embodiment, when the operating parameters include the intake exhaust gas concentration and the outlet exhaust gas concentration, determining the operating state of the exhaust gas purification apparatus according to the operating parameters includes:
judging whether the concentration difference between the exhaust gas concentration at the air inlet and the exhaust gas concentration at the air outlet is larger than a preset concentration difference or not;
if so, determining that the working state of the waste gas purification device is a normal state;
if not, the working state of the exhaust gas purification device is determined to be a fault state.
In order to accurately determine the working state of the exhaust gas purification device, in the application, the working state of the exhaust gas purification device can be determined according to a single working condition parameter, and can also be determined according to the combination of a plurality of working condition parameters. Specifically, when other working condition parameters of the exhaust gas purification device and the exhaust gas concentration at the air inlet are normal, if the concentration difference value is greater than the preset concentration difference value, the exhaust gas concentration at the air outlet is low, and then the adsorption layer can effectively purify the exhaust gas; if the concentration difference is smaller than the preset concentration difference, the exhaust gas concentration at the air outlet is high, and then the adsorption layer cannot effectively purify the exhaust gas, under the condition that other working condition parameters are normal, the adsorption material in the adsorption layer is likely to be saturated or saturated, and cannot be continuously adsorbed, so that the working state of the exhaust gas purification device can be determined to be a fault state, and a user is informed to timely replace the adsorption material in the adsorption layer. Based on this, through air intake waste gas concentration and air outlet waste gas concentration, can accurate definite exhaust gas purification device's operating condition.
As a preferred embodiment, when the operating condition parameter includes the wind speed at the wind inlet, determining the operating state of the exhaust gas purifying device according to the operating condition parameter includes:
judging whether the air speed of the air inlet is larger than a first preset air speed and smaller than a second preset air speed or not;
if the wind speed is not less than the first preset wind speed and not more than the second preset wind speed, determining that the working state of the waste gas purification device is a normal state;
otherwise, determining the working state of the waste gas purification device as a fault state;
wherein the first preset wind speed is not more than two preset wind speeds.
In order to accurately determine the working state of the waste gas purification device, in the application, when the working condition parameters include the air speed of the air inlet, the air speed of the air inlet needs to be ensured not to be too large or too small, and considering that the adsorption capacity of the adsorption material is limited, when more VOCs waste gas is contained in the air, the waste gas cannot be rapidly purified by the adsorption layer, and more time is needed for complete purification; if the air speed of the air inlet is too high, the waste gas is discharged after entering the adsorption layer and the adsorption material does not effectively adsorb VOCs, which is equivalent to exceeding the purification capacity range of the adsorption material; if the air speed of the air inlet is too slow, although the adsorption layer can timely and completely purify the waste gas in the air, the amount of the purified waste gas is too small, and the purification effect in an actual use scene is too small. Therefore, it is necessary to ensure that the wind speed at the air inlet cannot be too fast or too slow, and it is necessary to ensure that the wind speed is within a normal wind speed range. Based on this, by determining whether the air speed of the air inlet is between the first preset air speed and the second preset air speed, the working state of the waste gas purification device can be accurately determined.
As a preferred embodiment, before determining that the operating state of the exhaust gas purification apparatus is the normal state, the method further includes:
determining the air quantity of an air inlet of the waste gas purification device according to the air speed of the air inlet;
judging whether the air volume of the air inlet is larger than a first preset air volume and smaller than a second preset air volume;
if the air quantity is larger than the first preset air quantity and smaller than the second preset air quantity, the step of determining that the working state of the waste gas purification device is a normal state is carried out;
otherwise, determining the working state of the waste gas purification device as a fault state;
wherein the first preset air volume is not more than two preset air volumes.
In order to accurately determine the state of the air inlet, the air quantity of the air inlet can be further determined according to the air speed of the air inlet besides the air speed of the air inlet. Specifically, the air volume of the air inlet is determined according to the air speed of the air inlet and the cross-sectional area of a pipeline of the air inlet, the air volume of the air inlet is equivalent to the volume of air entering the air inlet in unit time, if the air volume of the air inlet is too large, it is indicated that air with a larger volume enters the air inlet in unit time, and due to the limited adsorption capacity of an adsorption material, the too large air volume can cause the quantity of waste gas to be purified to exceed the capacity range of the adsorption material, so that the waste gas cannot be effectively purified by an adsorption layer, and in addition, the too large air volume also indicates that the problems of dilution discharge and over-standard discharge rate can exist; if the air quantity of the air inlet is too small, the volume quantity of the air entering the air inlet in unit time is too small, although the adsorption layer can timely and completely purify the waste gas in the air, the quantity of the purified waste gas is too small, the purification effect in an actual use scene is too small, the small air quantity can be caused by the fact that a pipeline of the air inlet is damaged or a fan of the air inlet is aged, the problems of low pollutant capture rate and inorganization dissipation are caused, and the adsorption layer cannot effectively purify the waste gas; therefore, under normal conditions, the air quantity of the air inlet needs to be ensured not to be too large or too small, and the air quantity needs to be ensured within a normal air quantity range. Based on this, the state of the air inlet can be accurately determined by judging whether the air volume of the air inlet is between the first preset air volume and the second preset air volume.
As a preferred embodiment, when the condition parameter includes a material temperature, determining the operation state of the exhaust gas purification apparatus based on the condition parameter includes:
judging whether the temperature of the material is greater than a preset temperature or not;
if so, determining that the working state of the waste gas purification device is a normal state;
if not, the working state of the exhaust gas purification device is determined to be a fault state.
In order to accurately determine the operating state of the exhaust gas purification device, in the present application, it is considered that the adsorption capacity of the adsorption material is related to the temperature of the adsorption material, and therefore, a temperature detection unit may be disposed in the adsorption layer of the exhaust gas purification device, such as a thermal resistor or a thermocouple, to detect the temperature of the adsorption material, although the higher the temperature of the adsorption material is, the worse the adsorption capacity is, the less the change of the adsorption capacity when the temperature of the adsorption material is too low is, and therefore, it is not necessary to ensure that the temperature of the adsorption material is within a certain temperature range, and it is only necessary to judge whether the temperature of the adsorption material is greater than a certain preset temperature threshold, and the preset temperature may be set according to the material of the adsorption material used specifically. In practical application, when the temperature of adsorption material was higher, can unable effective adsorption and the exhaust gas in the air-purifying, when adsorption material was combustible material, higher temperature still probably led to the adsorption material to have the risk of spontaneous combustion or ignition, caused exhaust gas purification device to damage, economic loss and influence user's personal safety, so need guarantee that the temperature of adsorption material in practical application is less than preset the temperature. Based on this, by judging whether the material temperature is greater than the preset temperature, the operating state of the exhaust gas purification apparatus can be accurately determined.
As a preferred embodiment, when the operating condition parameter includes a pressure difference of the adsorption layer, acquiring an operating condition parameter of the exhaust gas purification apparatus includes:
determining a first air pressure at an air inlet of the adsorption layer;
determining a second air pressure at the air outlet of the adsorption layer;
and determining the air pressure difference value between the first air pressure and the second air pressure as the air pressure difference of the adsorption layer.
In order to accurately determine the operating state of the exhaust gas purification device, in this application, the air pressure difference refers to the air pressure at the air inlet of the adsorption layer and the air pressure at the outlet of the adsorption layer in the exhaust gas purification device, and under normal conditions, it is necessary to ensure that the air pressure difference fluctuates within a preset air pressure range. Specifically, in an actual application scenario, the first air pressure is generally only related to the air speed and the air volume of the air inlet, while the second air pressure is related to the adsorbing material of the adsorption layer besides the two parameters, generally, the first air pressure is higher than the second air pressure under normal conditions, if the air pressure difference is too large, the adsorption layer is blocked, and the exhaust gas purification device cannot normally exhaust gas, which is generally because the air has solid reasons besides gas hazards, and as the use time increases, the solids accumulated in the adsorption layer increase more and more, and finally the adsorption layer is completely blocked; if the atmospheric pressure difference is undersize, it does not normally purify waste gas to explain the adsorbed layer, this usually because the hazardous substances in the air can corrode adsorption material, thereby lead to the cavity grow in the adsorbed layer, if there is certain cavity to run through whole adsorbed layer completely, then be equivalent to forming a pipeline, waste gas can directly pass through the pipeline discharge in the adsorbed layer after being inhaled the air intake, the adsorbed layer does not purify these waste gases, therefore, when the in-service use, need guarantee that the atmospheric pressure difference is in predetermined atmospheric pressure scope, if the atmospheric pressure difference is too big or undersize, all explain waste gas purification device trouble. Based on this, the operating state of the exhaust gas purification apparatus can be accurately determined.
As a preferred embodiment, after determining the operating state of the exhaust gas purification apparatus according to the operating condition parameters, the method further comprises:
if the working state of the waste gas purification device is a fault state, generating an alarm signal;
and sending the alarm signal to a prompt module so that the prompt module sends a prompt.
In order to prompt a user in time, in the application, after the fault of the exhaust gas purification device is determined, specifically, fault information including a fault reason can be generated and sent to the user, so that the user can execute a corresponding action according to the fault reason, for example, when a fault that the air speed of the air inlet is too slow occurs, the fault information including the too slow air speed can be sent to a personal terminal of the user to prompt the user, so that the user can replace the air inlet fan or maintain the air inlet fan in time. In addition, a 4G network module may be set to implement direct connection transmission in a 4G network or a wired network, and the working condition parameters and the prompt information are compiled according to a preset communication protocol and then sent to a user terminal, so that a user may perform operations such as data summarization and analysis, please refer to fig. 3, and fig. 3 is a schematic diagram of a working condition parameter record file provided by the present application. The communication protocol includes, but is not limited to, TCP/IP, MQTT (Message queue Telemetry Transport), and the like, and in practical applications, real-time operating condition parameters are transmitted to the cloud, and are displayed on corresponding software applications for users to view, and after detecting that the exhaust gas purification device has a fault, short messages or mails are actively sent to a personal terminal of the user to prompt the user in time.

As a preferred embodiment, acquiring an operating condition parameter of the exhaust gas purification apparatus, and determining an operating state of the exhaust gas purification apparatus according to the operating condition parameter, includes:
continuously acquiring working condition parameters for N times, wherein N is an integer not less than 2;
determining the ratio of the number of the working condition parameters which represent that the working state is a fault state to N in the N working condition parameters;
judging whether the ratio is smaller than a preset ratio or not;
if so, determining that the working state of the waste gas purification device is a normal state;
if not, the working state of the exhaust gas purification device is determined to be a fault state.
Considering that the exhaust gas purification belongs to a long-term operation, and the process of the exhaust gas purification is simple and passive, and is not precise and complex, in order to avoid determining occasional emergencies as real faults of the exhaust gas purification device, in the application, because the exhaust gas concentration in the air is not fixed and constant, and the exhaust gas concentration can be changed rapidly along with the operating state of the equipment releasing the exhaust gas in the surrounding environment, the situation that the exhaust gas concentration at the air outlet is too high due to the fact that the adsorption layer cannot adsorb so much exhaust gas due to the fact that the exhaust gas concentration at the air inlet is increased instantly can occur; the air speed and the air pressure difference of the air inlet of the waste gas purification device can also change along with the change of the rotating speed, the working voltage and the stability of a fan of the waste gas purification device and the blocked area of the air inlet, and the air speed and the air pressure difference can often continuously fluctuate, so that the condition that the instantaneous air speed or the air pressure difference is too high or too low occurs; the temperature of the adsorbent material in the adsorbent layer may also vary with the environment, and the temperature of the adsorbent material may be affected by the ambient temperature, whether a heat source or a heat dissipation unit is nearby, whether sunlight is directly radiated, and the wind speed of the surrounding environment, and thus the temperature may also be momentarily too high. Many of the above-described cases are generally unstable in a short period of time, and these cases may occur even when the exhaust gas purification apparatus is completely normal. Since the purification of the exhaust gas is not a demanding, precise and complex operation, if the abnormal conditions of the working condition parameters occur several times occasionally within a period of time, the abnormal conditions can be ignored, but the abnormal times need to be recorded for the subsequent judgment; in a period of time, if the condition of the abnormal condition parameter frequently occurs, please refer to fig. 3, fig. 3 is a schematic diagram of a historical parameter curve of the condition parameter provided by the present application, fig. 3 shows the curve of the condition parameter in a period of time, specifically, a temperature curve, and it can be seen that a case of a high amplitude value occurs many times in a visible frame, that is, a case of the abnormal condition parameter multiple times occurs in the period of time, and then it can be said that the exhaust gas purifying apparatus is in a fault state. Based on this, by judging whether the ratio is larger than the preset ratio, it is possible to not only detect whether the exhaust gas purification apparatus is malfunctioning, but also avoid determining an occasional emergency as a real malfunction of the exhaust gas purification apparatus.
