Problems solved by technology

Ordinary air conditioners and air purifiers work by filtering particulate matter through a filter, although they can significantly reduce PM 2.5 However, the filter membrane needs to be cleaned and replaced frequently, and the high-density filter membrane requires a large pressure difference, which requires the high-speed operation of the fan to provide power, which is prone to generate greater noise and more energy consumption.

Abstract

The invention relates to a novel spraying agent for reducing indoor haze, and an application thereof, and belongs to the technical field of air cleaning. The novel spraying agent for reducing indoor haze adopts a nitrogen-containing alkaloid plant extract product as a main active component, the main active component is compounded with polyvinylpyrrolidone and glycosaminoglycan, and a polyvinylpyrrolidone, glycosaminoglycan and deionized water mixture is wrapped into a respirable particle through the adsorption of the nitrogen-containing alkaloid, so the indoor haze concentration is effectively reduced. The spraying agent can be directly added into a sprayer and is used for indoor sprinkling to remove suspension particle dusts in air and reduce haze; and the spraying agent can be matched with an air conditioner to reduce indoor haze in order to reduce the indoor haze concentration and make indoor environment reach below third level in Technical Regulation on Ambient Air Quality Index HJ633-2012.

Description

technical field [0001] The invention relates to a spray and its application, in particular to a novel spray that can reduce indoor smog and its application, and belongs to the technical field of air purification. Background technique [0002] In recent years, medical research has shown that the incidence of lung cancer is on the rise, especially the incidence of lung cancer among non-smokers is also on the rise. Xiao Chunling and others in "PM 2.5 Air Pollutants Induced Pathological Changes of Respiratory System in Rats pointed out that air pollutants can cause the weakening and loss of swing function of tracheal cilia in rats, leading to its excretion dysfunction; Wang Qin, Li Tiantian, Chen Chen et al. weather PM 2.5 Pollution Characteristics and Its Impact on Population Health" pointed out that the increase of respiratory symptoms, the decrease of lung function, the exacerbation of asthma, the occurrence of chronic bronchitis, the premature death of patients with arrhyt...
