Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, and in particular to a dust removal device and system for a textile workshop based on big data. Background Art

[0002] A textile factory is a factory that uses machinery to manufacture means of production or means of living. A textile workshop is a place where textile raw materials are processed and manufactured, mainly in the textile industry. Textile raw materials include cotton, cashmere, wool, silk cocoons, chemical fibers, feathers, down, etc. The downstream industries of the textile industry mainly include the clothing industry, household textiles, industrial textiles, etc. The textile industry is subdivided into cotton textiles, chemical fibers, linen textiles, wool textiles, silk, textile knitting industry, printing and dyeing industry, etc.

[0003] During the textile process, a large amount of cotton dust, that is, plant dust such as cotton and linen, is produced. This type of dust is flammable and may cause an explosion. Textile workers who inhale cotton dust for a long time will suffer from cotton dust disease, which is extremely harmful to the human body.

[0004] Existing cotton dust concentration detection devices mostly use high-intensity suction pumps to suck a certain amount of air and filter it to obtain the weight of the cotton dust filtered out of a certain amount of air, and then the weight of the cotton dust in a certain volume of air can be obtained.

[0005] However, the existing dust removal device for textile workshops cannot adjust the treatment means in real time according to the cotton dust concentration; at the same time, the existing dust removal device for textile workshops cannot adjust the treatment intensity in real time according to the cotton dust concentration. Therefore, it is necessary to design a dust removal device and system for textile workshops based on big data that can adjust the treatment means and treatment intensity in real time according to the cotton dust concentration. Summary of the invention

[0006] The purpose of the present invention is to provide a dust removal device and system for a textile workshop based on big data to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: A dust removal device for a textile workshop based on big data, comprising a dust removal cylinder, characterized in that: a filter is arranged on the outside of the dust removal cylinder, an isolation cylinder is arranged inside the dust removal cylinder, a plurality of groups of pressure valves are arranged inside the isolation cylinder, an air intake pipe is arranged below the dust removal cylinder, a first valve is arranged above the dust removal cylinder, an exhaust pipe is arranged above the first valve, two humidifiers are arranged inside the dust removal cylinder, a group of second valves are arranged on the lower side of the dust removal cylinder, a cleaning pipe is arranged on one side of the group of second valves, and a dust suction pump is arranged on one side of the cleaning pipe.

[0008] According to the above technical solution, the dust removal system includes a detection module, a sedimentation module, a filtering module, and a spraying module. The detection module is electrically connected to the sedimentation module, the detection module is electrically connected to the filtering module, and the detection module is electrically connected to the spraying module.

[0009] The detection module is used to detect the concentration and temperature of external cotton dust, the sedimentation module is used to remove cotton dust through natural sedimentation, the filtration module is used to filter cotton dust in the air, and the spraying module is used to spray water vapor to make the external cotton dust settle quickly and alarm to notify relevant staff that the cotton dust concentration here has exceeded the standard.

[0010] According to the above technical solution, the detection module includes a detection unit and a feedback module, the sedimentation module includes a sedimentation unit and a control unit, the detection unit is electrically connected to the feedback module, and the control module is electrically connected to the feedback module;

[0011] The function of the detection unit is to detect the concentration of external cotton dust and the external temperature. The function of the feedback module is to receive the signal of the detection unit and feed the signal back to each module of the dust removal system. The function of the sedimentation unit is to settle the cotton dust in the discharged air to achieve the purpose of dust removal. The function of the control module is to control the humidity change so that the cotton dust can be fully settled.

[0012] According to the above technical solution, the filtering module includes a grading unit and a filtering unit, the spraying module includes an alarm module and a spraying unit, the filtering unit is electrically connected to the feedback module, the alarm module is electrically connected to the feedback module, and the spraying unit is electrically connected to the feedback module;

[0013] The function of the grading unit is to separate the sedimentation module from the filtering module to avoid mutual interference between the two. The function of the filtering unit is to filter the air. The function of the alarm module is to remind relevant staff that the concentration of cotton dust outside is too high and cannot be effectively handled. The function of the spraying unit is to increase the external environmental humidity so that the cotton dust outside can be directly settled.

[0014] According to the above technical solution, the dust removal system includes the following working steps:

[0015] S1: Real-time detection of cotton dust concentration and external temperature in the external environment;

[0016] S2: When the cotton dust concentration is higher than the normal value, that is, when the air with a concentration higher than this value begins to be harmful to the human body, dust removal begins, and the treatment method and treatment speed are determined according to the concentration of the external cotton dust;

[0017] S3: Process the cotton dust, and when the cotton dust inside accumulates to a certain amount, start to remove the accumulated cotton dust inside;

[0018] S4: When the concentration of cotton dust returns to the normal value or below, the dust removal is stopped, and when the concentration of cotton dust outside is detected to be high again, steps S2-S4 are repeated.

[0019] According to the above technical solution, the above step S2 also includes the following steps:

[0020] S21: When the cotton dust concentration is greater than or equal to 20 mg / m 3 When the dust concentration is lower than 50mg / m 3 The dust collection is started at the same time, and during the sedimentation process, the sedimentation humidity increases with the increase of cotton dust concentration;

[0021] S22: When the cotton dust concentration is greater than or equal to 50 mg / m 3 and less than 200mg / m 3 When the filter dust removal is started, the filtering efficiency of the process is instantly accelerated. During the filtering process, the filtering speed is proportional to the concentration of cotton dust. However, this filtering method is prone to cause the filter to become clogged and fail, and the economic cost of using it is high.

[0022] S23: When the cotton dust concentration is greater than 200 mg / m 3 When the dust concentration in the local area has reached the lower limit of dust explosion, it will cause damage to the life safety of relevant staff. Therefore, the alarm device will be triggered here to notify the relevant staff and quickly spray water mist to the outside world to make the dust gather and settle quickly. The rate of water mist spraying is related to the concentration of cotton dust.

[0023] According to the above technical solution, in the above step S21, the internal humidity is adjusted, so that the fibers in the cotton dust absorb water and increase weight to settle. At this time, the humidity can directly affect the water absorption of the cotton dust, and the temperature of the cotton dust will also affect the equilibrium moisture regain of the cotton dust, that is, when the humidity is constant, the higher the temperature, the smaller the water absorption of the cotton dust, and as the concentration of the cotton dust increases, and because the passing rate of the cotton dust remains unchanged, in order to ensure that the cotton dust can be completely settled, it is necessary to make a certain adjustment to the humidity to make it slightly larger than the required humidity, so as to avoid excessive instantaneous water absorption due to excessive cotton dust, so that part of the cotton dust cannot absorb enough water vapor and settle;

[0024] The internal humidity n can be calculated according to the following formula:

[0025]

[0026] Where: σ is the correction coefficient, T is the temperature of the air containing cotton dust, n 凝To obtain the humidity that can make cotton dust settle from big data, and the humidity will change with the type of textile factory production, that is, the content of each part of the cotton dust. Q is the concentration of cotton dust in the air, and q1 is the safe cotton dust concentration, that is, 20mg / m 3 .

[0027] According to the above technical solution, in the above step S22, when the cotton dust concentration is too high, it is necessary to start the filtering dust removal system to prevent the relevant staff from inhaling the air with too high cotton dust concentration and causing harm to their bodies. At this time, the dust removal speed of the sedimentation dust removal method is too low to quickly reduce the cotton dust concentration. During filtering, the filtration speed is too fast, which can easily cause the cotton dust to be squeezed onto the filter, causing the filter to be easily blocked. When the cotton dust is removed by filtration, it is necessary to determine the air velocity during filtration according to the cotton dust concentration. When the cotton dust concentration is proportional to the air velocity during filtration, it can ensure that the cotton dust concentration can be quickly reduced while avoiding clogging of the filter.

[0028] According to the above technical solution, the above step S23 also includes the following steps:

[0029] S231: When the cotton dust concentration is greater than 200 mg / m 3 , but less than 250mg / m 3 At this time, it is judged that the cotton dust concentration in the local area is greater than the measured value and has reached the lower explosion limit, so the alarm is activated and a certain intensity of water mist is sprayed only to the area where cotton dust is likely to be generated as determined by big data, so as to remind relevant staff and prevent the occurrence of danger to a certain extent;

[0030] S231: When the cotton dust concentration is greater than 250 mg / m 3 , cotton dust concentration is greater than 250mg / m 3 , indicating that most areas of the textile factory have reached the lower explosion limit. At this time, the alarm is activated and water mist is sprayed in all directions. The intensity of the water mist spray increases with the increase of cotton dust concentration to avoid accidents.

[0031] According to the above technical solution, the above step S3 also includes the following steps:

[0032] S31: When using sedimentation dust removal, it is only necessary to judge whether dust removal is needed by judging the weight, that is, it is sufficient to judge by weight that the dust is not too much;

[0033] S32: When using filtering to remove dust, the wind speed must be considered. The faster the wind speed, the faster the dust needs to be removed to avoid the accumulated dust generating secondary dust that blocks the filter.

[0034] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention determines the treatment method by real-time detection of the concentration of cotton dust, and when the cotton dust is treated, the treatment intensity will also change with the change of the cotton dust concentration, so as to achieve the purpose of both good treatment of cotton dust and reduction of economic costs, and when the cotton dust concentration is too high, an alarm will be triggered to remind relevant staff to avoid danger.

The function of the spraying unit is to increase the external environmental humidity so that the cotton dust outside can be directly settled.

[0047] The dust removal system includes the following working steps:

[0048] S1: Real-time detection of cotton dust concentration and external temperature in the external environment;

[0049] S2: When the cotton dust concentration is higher than the normal value, that is, when the air with a concentration higher than this value begins to be harmful to the human body, dust removal begins, and the treatment method and treatment speed are determined according to the concentration of the external cotton dust;

[0051] S4: When the concentration of cotton dust returns to the normal value or below, the dust removal is stopped, and when the concentration of cotton dust outside is detected to be high again, steps S2-S4 are repeated.

[0052] The above step S2 further includes the following steps:

[0053] S21: When the cotton dust concentration is greater than or equal to 20 mg / m 3 When the dust concentration is lower than 50mg / m 3 The dust collection is started at the same time, and during the sedimentation process, the sedimentation humidity increases with the increase of cotton dust concentration;

Therefore, the alarm device will be triggered here to notify the relevant staff and quickly spray water mist to the outside world to make the dust gather and settle quickly. The rate of water mist spraying is related to the concentration of cotton dust.

[0056] In the above step S21, the internal humidity is adjusted so that the fibers in the cotton dust absorb water and increase weight to settle. At this time, the humidity can directly affect the amount of water absorbed by the cotton dust, and the temperature of the cotton dust will also affect the equilibrium moisture regain of the cotton dust, that is, when the humidity is constant, the higher the temperature, the smaller the amount of water absorbed by the cotton dust, and as the concentration of the cotton dust increases, and because the passing rate of the cotton dust remains unchanged, in order to ensure that the cotton dust can be completely settled, it is necessary to make a certain adjustment to the humidity to make it slightly larger than the required humidity, so as to avoid excessive instantaneous water absorption due to excessive cotton dust, so that part of the cotton dust cannot absorb enough water vapor and settle;
