Description

Technical Field

[0001] The utility model relates to an anti-clogging high-efficiency smoke and dust filtering detection device. Background Art

[0002] With the acceleration of industrialization and urbanization, air pollution is becoming increasingly serious, and smoke emissions have a significant impact on the environment and human health. Therefore, real-time monitoring of smoke concentration and its composition has become a critical research topic. Existing smoke detection equipment mostly uses optical or electrochemical methods. While these technologies offer advantages in accuracy and sensitivity, they also have some drawbacks.

[0003] Existing filter designs are often easily clogged by small particles. Although the primary function of filters is to remove larger particles to protect subsequent sensors from damage, in practice, fine particles and impurities can accumulate on the filter surface, increasing airflow resistance. This not only reduces sampling efficiency but can also slow the device's response, affecting the accuracy of monitoring results. Furthermore, frequent maintenance and filter replacement increases equipment operating costs.

[0004] Therefore, there is an urgent need for a new type of smoke detection device that can effectively prevent clogging by small particles of debris and improve the accuracy and real-time performance of detection to meet the needs of modern environmental monitoring. Utility Model Content

The multi-stage filter device comprises a housing, which includes a top surface, a bottom surface, a left side surface, and a right side surface. The top surface of the housing is provided with a plurality of slots for inserting filter assemblies. The filter assemblies are replaceable structures. The filter assembly includes two symmetrically arranged fixing plates, which are connected to form inserts that match the shape of the slots. The fixing plates are provided with grooves for placing filter material. The front of the housing is connected to a metal filter screen by magnetic attraction. The metal filter screen is provided with locating pins at the four corners. The front of the housing is provided with locating holes that match the locating pins. The back of the housing is provided with a three-way pipe, which is respectively connected to the housing, the air inlet of the detection device, and the anti-clogging backflush device.

The anti-clogging backflush device includes a backflush blower, and a positive suction blower is provided at the air inlet.

[0007] As a further improvement, the cross-section of the slot on the top surface of the shell is I-shaped, the right-angled edges in the slot are chamfered, and the entrance of the slot is chamfered, which can make it easier to insert the filter component into the slot.

[0008] As a further improvement, the pore size of the metal filter is 1 mm to 5 mm, which can effectively prevent small particles of debris from entering the detection device.

[0009] As a further improvement, the filter material is polyester fiber or glass fiber, which is light, low in cost, and can capture tiny particles.

[0010] As a further improvement, the three-way pipe is connected to the shell through a flange, and a sealing strip is provided on the connection surface, which facilitates the connection and enhances the air tightness.

[0011] As a further improvement, both the positive suction fan and the reverse blower are adjustable speed fans, which can adjust the air volume according to actual needs, improve the working efficiency and service life of the equipment, which is particularly important in smoke detection devices, so as to maintain a stable sampling rate under different concentrations and environmental conditions.

[0012] Beneficial effects:

[0013] The use of advanced multiple sensor technologies, combined with laser scattering and electrochemical analysis, can accurately measure smoke concentration and its composition, improving data reliability.

[0014] The multi-stage filtration design effectively prevents clogging by small particles, reduces the frequency of filter cleaning and replacement, and thus reduces equipment maintenance and operating costs.

[0020] A clog-resistant, high-efficiency smoke filter detection device includes an air inlet, a detection device, a data processing module, and a display module. The detection module contains a laser scattering sensor and an electrochemical sensor. The data processing module includes a microprocessor and memory. The display unit includes an LED display and an audible and visual alarm. Smoke gas from the environment is introduced into the device through the air inlet. Upon entering the detection module, the laser scattering sensor emits a laser beam. When the beam passes through the gas, smoke particles in the gas scatter the laser light. The sensor receives the scattered light and calculates the smoke concentration based on the scattered light intensity. Simultaneously, the electrochemical sensor analyzes the gas sample and measures the concentrations of harmful components in the smoke, such as carbon monoxide and sulfur dioxide, thereby providing more comprehensive monitoring data. The data processing module receives the data fed back by the sensors and uses a built-in algorithm to analyze and calculate the data to obtain real-time smoke concentration and composition information. The detection results are displayed in real time on the display unit, allowing the user to intuitively see the smoke concentration and composition. The data processing module also stores the results and supports data export and remote monitoring. If the smoke concentration exceeds a preset threshold, the device triggers an audible and visual alarm, prompting the user to take necessary measures.
