Device for eliminating haze and atmospheric pollutant

Abstract

The invention discloses a device for eliminating haze and atmospheric pollutants. Appropriately preheated atmosphere with pollutants flows through a capillary tube array and is introduced into a liquid adsorbent, the pollutants in the atmosphere inside formed bubbles are adsorbed or dissolved by the surface of the liquid inside the bubble, and then atmosphere purification is achieved. The purification is applicable to atmospheric suspended grains of various diameters, and pm2.5 purification can be thoroughly achieved. To enhance the purification effect and the use convenience, the device is provided with function components such as a stirring rod with a bubble cutting steel wire and a spiral belt, and a waste liquid sucking chamber. The device can be separately used and can be also used with other devises in series. The device can be mounted on various carrying tools such as a vehicle, and due to the position change, the haze cleaning places can be changed at appropriate time, and the movement airflow of the carrying tool can be used as the power for eliminating the haze. The device can be used for purifying air at fixed points. When the device is used together with dust cleaning equipment, pm2.5 purification in polluted enterprises can be achieved. With special liquid adsorbent, the device can be used in special purification and professional equipment.

Description

technical field [0001] 　 The invention relates to the removal and prevention of air pollution, and can also be used for the removal of local air pollution. Specifically, it is a device for removing atmospheric haze and air pollution. The decontamination principle of the device involves the principle or concept of gas-liquid mass transfer in chemical industry . Background technique [0002] 　 Haze is mainly composed of three items: sulfur dioxide, nitrogen oxides and inhalable particulate matter. In the weather with high humidity, it combines with water vapor in the air to make the sky gray, which is called haze weather. Smog contains a variety of harmful substances and is the carrier of pollutants, causing harm to the human respiratory system, cardiovascular and cerebrovascular systems, nervous system, reproductive system and skin. The smaller the smog, the more toxic it is to the lungs, and long-term inhalation can lead to lung cancer. Smog also absorbs and scatters so...

Problems solved by technology

[0008] The second type, spray method, this method absorbs suspended particles or harmful gases through liquid mist beads, which is harmful to relatively large local environments such as coal-fired boilers and steelmaking. The removal effect of particle dust is obvious, but this kind of equipment needs to be equipped with complex functional modules such as increasing / decreasing, cooling, fogging, and defrosting. Suitable for large-scale air purification;

[0009] The third category, physical / chemical methods, such as negative ion method, photocatalyst method, electrostatic precipitator, etc., but such devices either have slow cleaning speed or have their specific working conditions and site constraints, usually only suitable for air purification in limited spaces

[0010] The above-mentioned cleaning principles are not suitable for removing atmospheric smog. The reasons are as follows: First, the degree of air pollution varies greatly, and the distribution range is wide. In severe cases, high flux is required Cleaning treatment; Second, there are many haze-causing factors and large changes in atmospheric temperature / humidity, requiring the cleaning method adopted to adapt to various conditions and occasions. General air purification devices have very limited effects when used for atmospheric haze removal; Third, clearing The power consumption of smog operations is also one of the key factors. Due to the large amount of air to be processed and the uneven distribution of pollution, general air purification devices have poor energy efficiency when used for atmospheric haze removal.
