Embodiment Construction

[0017] A filtration system based on membrane equipment, including a central control module, a harmful gas detection module, and an infrared detection module;

[0018] The central control module includes a membrane filtration unit, a component analysis unit, and a database;

[0019] The membrane filtration unit acquires control parameters for controlling the operating state of the membrane filtration equipment;

[0020] The component analysis unit obtains the concentration of pollutants, and retrieves control parameters from the database and sends them to the membrane filtration unit. The concentration of pollutants includes the concentration of harmful gases and the concentration of suspended solids;

[0021] Control parameters are stored in the database, preferably, each control parameter is associated with a pollutant concentration;

[0022] The harmful gas detection module is a gas sensor, and the harmful gas detection module is used to detect the harmful gas content in th...

Abstract

The invention discloses a filtering method based on membrane equipment. The method comprises the following steps: a solid suspended matter concentration in air is obtained by an infrared receiving device and sent to a component analyzing unit; a harmful gas content is obtained by a harmful gas detection module and sent to a component analyzing unit; a pollutant concentration is obtained by the component analyzing module to be compared with a standard pollution concentration; repeated detection signals are sent to the harmful gas detection module and the infrared detection module by the component analyzing module; a database is traversed by the component analyzing module to search for a control parameter related to the pollutant concentration, and the control parameter is sent to a membrane filtering unit. According to the filtering method based on the membrane equipment disclosed by the invention, the gas sensor is utilized to detect harmful gas, the infrared device is utilized to detect the solid suspended matter concentration in the air, and the pollutant concentration in the air is repeatedly filtered until air quality meets a standard. The filtering method disclosed by the invention has the advantages of having an intelligent and safe system, achieving automatic control, improving a filtering efficiency and reducing energy waste.

Description

technical field [0001] The invention belongs to the technical field of membrane equipment filtration, in particular to a membrane equipment-based filtration method. Background technique [0002] With the rapid development of membrane filtration technology and the increasing localization of membrane filtration equipment, membrane filters are gradually being favored by the fermentation industry for their advantages such as large filtration area, small equipment volume, high filtration efficiency, and low pressure loss. However, traditional air purification systems mostly use cotton as the filter medium, which seriously restricts the development of enterprises due to its shortcomings such as large pressure drop, high operating costs, and complicated replacement. Contents of the invention [0003] The purpose of the present invention is to provide a filtration method based on membrane equipment. The system of the present invention is intelligent and safe, implements automatic ...
