Microalgae air purifier automatic control system and control method

Abstract

The invention discloses a microalgae air purifier automatic control system which comprises a purifier body and a control element. The purifier body comprises an uncovered rectangular transparent microalgae storage tank and a barrel, the microalgae storage tank comprises a heater A, an air inlet, a temperature sensor, a toxic and harmful gas detection probe, a PM2.5 detection probe and a fluorescent lamp. The barrel is of a bottomless covered sectioned nested type, a gauze layer is arranged between sections, a sprayer is arranged on each gauze layer except for the uppermost gauze layer and fixedly connected with a water pump through a pipeline, the water pump is communicated with the microalgae storage tank, a temperature and humidity sensor is mounted inside the barrel, a fan is fixedly mounted on the surface of the barrel, and a heater B is fixedly mounted below the fan. The invention further discloses a control method of the automatic control system. The control method has the advantages of fine purification effect, low cost, easiness in operation and maintenance and the like, can be used for treating various waste gases such as industrial waste gas by slight improvement and is wide in application range.

Description

[0001] technical field [0002] The invention relates to the technical fields of environmental engineering and automation, in particular to an automatic control system and control method for a microalgae air purifier. Background technique [0003] In recent years, people in the central and eastern regions of the country have been living in the explosion of PM2.5. From the northeast to the northwest, from the north to the central part and even the Huanghuai and Jiangnan regions, the people are suffering from severe and serious pollution on a large scale. Beijing, Shijiazhuang Beijing, Tianjin, Hebei, Baoding, Handan, Tianjin, Cangzhou, Langfang, Tangshan and other Beijing-Tianjin-Hebei regions have issued orange warnings for heavy fog. Provinces and cities such as Shandong, Sichuan, and Anhui have issued yellow or orange warnings. Xinxiang and Kaifeng in Henan have even issued heavy fog warnings. Fog red warning sign. In hospitals, sickness related to air pollution is increa...

Problems solved by technology

[0007] However, the existing air purifiers only use one kind of air purification technology, and the pollutants that can be treated are relatively single

Existing activated carbon air purifiers often face the problem of overloading the adsorption capacity of activated carbon and need to replace the activated carbon

Moreover, the existing air purifiers generally can only achieve the effect of absorbing pollutants, and the cost is relatively high, which is not conducive to maintenance
