Description

Technical Field

[0001] The invention relates to the technical field of pressure difference measurement, and in particular to a device for measuring the pressure difference of a dust collector body. Background Art

[0002] With the acceleration of industrialization, air quality issues are becoming increasingly serious, especially in terms of dust and particulate matter emissions, which have become an important issue in environmental protection. Dust collectors, as important equipment for controlling and reducing dust pollution in industrial waste gas, are widely used in various industrial production. Its working principle usually relies on the capture and purification of dust in the gas. In these processes, the pressure difference of the dust collector is a key performance indicator. Existing dust collectors use differential pressure gauges to detect the pressure difference. However, since the pressure pipe connected to the differential pressure gauge is too long and inconvenient to clean, it is easy to cause the pressure pipe to be blocked, making the pressure difference measurement of the dust collector inaccurate. Summary of the invention

DETAILED DESCRIPTION

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Figure 1 This is a traditional diagram of using a differential pressure gauge to measure the differential pressure of the dust collector body. Since the air inlet and outlet ducts of the dust collector body are too long, the pressure pipe connected to the differential pressure gauge is too long, which is inconvenient to clean and easily leads to blockage of the pressure pipe, making the differential pressure measurement of the dust collector inaccurate.

[0024] See also Figure 2 In order to solve the above problems, the present invention provides a device for measuring the pressure difference of a dust collector body, comprising:

[0025] A dust collector body 2, one end of which is connected to the air inlet duct 1, and the other end of which is connected to the air outlet duct 3;

[0026] An intake negative pressure gauge 7, arranged on the intake pipe 1, for measuring the intake pressure value of the intake pipe 1;

[0027] An outlet negative pressure gauge 9 is provided on the outlet pipe 3 and is used to measure the outlet pressure value of the outlet pipe 3;

[0028] The PLC system 8 is respectively connected to the air inlet negative pressure meter 7 and the air outlet negative pressure meter 9 for communication, and is used to determine whether the pressure difference of the dust collector body 2 is normal according to the air inlet pressure value and the air outlet pressure value.

[0029] During normal operation, there is a certain pressure difference inside the dust collector, and this value is monitored in real time through a differential pressure gauge. For example, when a bag dust collector is operating normally, the differential pressure is usually within a certain range (such as 500-2000Pa). If the differential pressure gauge reading exceeds this range, it may indicate that there is a problem with the dust collector.

[0030] Furthermore, when the difference between the intake pressure value and the outlet pressure value calculated by the PLC system is between 500-1500Pa, the pressure difference of the dust collector body 2 is within the normal range. When the difference between the intake pressure value and the outlet pressure value calculated by the PLC system is above 1500Pa, the pressure difference of the dust collector body 2 is abnormal, reminding the operator that there may be filter bag blockage, dust accumulation in the pipeline, etc., and a filter bag blockage or pipeline dust accumulation alarm is issued. When the difference between the intake pressure value and the outlet pressure value calculated by the PLC system is below 500Pa, the pressure difference of the dust collector body 2 is abnormal, which may be caused by filter bag damage or pipeline leakage, and a filter bag damage or pipeline leakage alarm is issued.

[0031] According to the specific embodiments provided by the present invention, the present invention discloses the following technical effects:

[0032] The present invention relates to a device for measuring the pressure difference of a dust collector body. Compared with the prior art, the present invention installs a negative pressure gauge on the air inlet pipe and the air outlet pipe of the dust collector body respectively, so that the pressure guiding pipe can be made very short, easy to clean and not easy to be blocked, thereby ensuring the accuracy and stability of the pressure difference measurement and facilitating timely discovery of the operation problems of the dust collector.
