Environmental monitoring plan for tobacco warehouse

tobacco, a special product, is very vulnerable to environmental impact. Therefore, the storage environment of tobacco is very important. A good tobacco warehouse should ensure that the temperature and humidity are within a certain range. Only in this way can the storage quality of tobacco be guaranteed. If the temperature and humidity are abnormal, it may lead to mildew and deterioration of tobacco. In the tobacco warehouse, we must strictly monitor the temperature and humidity, upload the temperature and humidity data of the monitoring points regularly, print the temperature and humidity curve for analysis, and eliminate all hidden dangers

If the temperature and humidity are abnormal, it may lead to mildew and deterioration of tobacco. In the tobacco warehouse, the temperature and humidity must be strictly monitored, and the temperature and humidity data of the monitoring points must be uploaded regularly, and the temperature and humidity curve must be printed for analysis, so as to eliminate all the hidden dangers of entering the oil cylinder through the oil valve

supply liquid crystal wall mounted temperature and humidity transmitter: the method is: take point B which is basically equal to the number of cells in the short segment from the pull-off point o on the long segment

communicate and understand the solution to view the product details. Composition of the temperature and humidity monitoring system in the tobacco warehouse:

1. Automatic temperature and humidity recorder: responsible for detecting and storing the temperature and humidity data at each point

2. Software part: the software part is responsible for reading, analyzing and printing all data

3. Host part: host (any computer) is used to read and view the data stored in the recorder

functions of temperature and humidity monitoring system in tobacco warehouse:

1. Collect and record the temperature and humidity in tobacco warehouse in real time

2. All temperature and humidity data are collected and recorded in the recorder, which can be poured into the computer through software

3. Users can query the historical data stored in the recorder for data analysis, printing and other operations

4. In case of abnormal conditions, the recorder records the data, and the red letter alarm and the recorder buzzes

advantages of tobacco warehouse temperature and humidity monitoring system:

1. Convenient construction, no wiring, no installation, internal power supply

2. The software has powerful functions, which can monitor data in real time and for a long time, print data, and set alarms

3. The recording interval and delay recording time are set randomly, both of which are 1 second to 24 hours

4. Liquid crystal display: the liquid crystal screen can display the ambient temperature and humidity, recorder power, recorder storage, and recording switch

summary:

adl automatic temperature and humidity recorder has two humanized monitoring methods: real-time monitoring and long-term monitoring. The installation cost of wiring is completely reduced. The recorder adopts internal power supply and can be placed at any monitoring point at will, which easily solves the environmental monitoring problem of tobacco warehouse. Small and beautiful body, powerful function. Supporting management software. It makes it easy for you to monitor the tobacco warehouse

expert answers and solutions in the use of vortex flowmeter

thermal mass flowmeter (hereinafter referred to as TMF) is an instrument that uses the heat transfer principle to detect the flow, that is, the heat exchange relationship between the flowing fluid and the heat source to measure the flow. In the past, it was called calorimetric flowmeter in China. TMF's early development focused on small gas flow instruments, and later developed to HVAC (heating, ventilation and air conditioning) and flue gas large pipe runoff measurement. In recent 10 years, it has developed rapidly in liquid micro flow measurement. However, the current measurement is still based on gas, which is described in this paper

vortex flowmeter refers to the application of hlug series intelligent vortex flowmeter, which is mainly used for the flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large range and high accuracy. It is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring volumetric flow under working conditions. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. This instrument adopts piezoelectric stress sensor, which has high reliability and can work within the working temperature range of -20 ℃ ~ +250 ℃. It has analog standard signal and digital pulse signal output, which is easy to be used with digital systems such as computers. It is a relatively advanced and ideal flow instrument

the main problem is that Shandong Hengxu Technology Co., Ltd. is a professional manufacturer of testing equipment for flexible packaging materials The instruction is not accurate for a long time

2. There is no indication at all

3. Indicates a wide range of fluctuations, unable to read

4. Indication does not return to zero

5. No indication at low flow

6. The indication is OK in case of large flow, and inaccurate in case of small flow

7. When the flow changes, the indication changes cannot keep up

8. The K coefficient of the instrument cannot be determined, and the data at many places are inconsistent

analysis and solution of main problems

it takes nearly half a year to analyze and solve these problems. Due to the complexity of the problems, there are different degrees of problems in the design and installation, parameter setting, daily maintenance, and operating environment. Many problems are involved in each other. In addition, the solution of some problems needs to wait for certain process operation opportunities, Therefore, it brings great difficulties to solve the problems. Some problems are caused by different reasons, and some reasons are related to different problems
