Description

TECHNICAL FIELD

[0001] The utility model relates to filter technology field, specifically a kind of intelligent automatic drainage gas filter. BACKGROUND

[0002] Gas filter is the key safety equipment in gas system, mainly used to filter the impurities and moisture in gas, ensure the purity of gas supply, improve the running stability of system. The traditional gas filter usually adopts manual drainage mode, i.e. through manual water drain valve to discharge the moisture stored in filter periodically. However, this manual operation mode has great limitation, not only needs artificial periodic inspection and operation, but also in the maintenance process, moisture can not be discharged in time due to human negligence, and then affect the safety and service life of gas system. In addition, although some gas filters introduce automatic drainage design, limited by water level detection and valve control precision, the accuracy and reliability of drainage are still low, which limits the operation efficiency of equipment.

[0003] The existing automatic drainage gas filter still has technical defects in water level monitoring and drainage control. Some equipment adopts ordinary floating ball type or electrode type water level detection method, which is easily affected by gas disturbance, impurity deposition or sensor aging, resulting in increased water level sensing error, thereby affecting the control precision of electromagnetic valve. In addition, the sealing property and response speed of electromagnetic valve are also important factors affecting the reliability of automatic drainage. If the sealing is not strict or the valve response is lagging, it may cause gas leakage or incomplete drainage problem, increasing the difficulty of system maintenance. At the same time, most of the existing gas filters are not equipped with installation stability detection means. When there is a small gap in the connection of water level sensor or electromagnetic valve, it is often not found in time, which may cause liquid leakage, affecting the sealing performance and long-term operation stability of the equipment.
