Antifreezing type dust aggregation agent and application thereof

Abstract

The invention relates to the field of chemical industries, in particular to an antifreezing type dust aggregation agent and application thereof. The dust aggregation agent is prepared from the following components in parts by weight: 1 to 5 parts of lauryl alcohol polyoxyethylene ether sulfate, 4 to 15 parts of polyoxyethylene lauryl ether, 2 to 8 parts of lauryl sulfate, 4 to 15 parts of iso-alcohol polyether, 2 to 7 parts of a wetting agent and 65 to 75 parts of water. The dust aggregation agent provided by the invention is prepared by the economical and environment-friendly raw materials; awhole preparation process is simple and easy to operate, and has no pollution to the environment. In addition, the dust aggregation agent is mixed with compressed air and then a mixture is ejected from a nozzle at high speed to form a high-speed atomization jet flow, so that surface tension of water droplets is reduced, the binding ability between water mist and dust is greatly improved, and thedust removal ratio reaches 95 percent or above; besides, no stagnant water is formed on the ground after mist spray. Moreover, the dust aggregation agent provided in the application has good stabilityat low temperature, and still has good effects of dust aggregation and flocculate sedimentation at lower temperature.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an antifreeze type dust agglomerate and application thereof. Background technique [0002] Dust pollution is harmful to the environment and human health, and has become a world pollution problem. With the deepening of my country's industrialization, the problem of dust pollution is becoming more and more serious. The dust sources mainly include deserts, highways, railways, docks, mines, coal yards, mining, quarrying, cement plants, chemical plants, thermal power plants and construction sites. Dust pollution not only causes a large amount of resource loss, but also pollutes the surrounding environment, affecting people's normal production and life. With the enhancement of environmental protection awareness, people pay more and more attention to the control of dust pollution, and the demand for effective dust prevention and suppression methods is more urgent. [0003] At present,...

Problems solved by technology

[0003] At present, the most commonly used dust suppression method in our country is the dust suppression method of sprinkling water. The function of sprinkling dust is mainly to moisten the fine dry dust and increase the moisture content of the dust, thereby increasing its density and bonding into larger particles. It can not fly under the action of external force, and the operation of sprinkling water is simple, but it needs to waste a lot of water resources, and in most cases, when the water evaporates, the dust content will increase sharply, and the anti-evaporation ability of water is poor, and the effective dust suppression time is longer Short (less than half an hour of high temperature in summer), poor cold resistance and easy to freeze

[0004] With the continuous development of technology in this field, chemical dust suppression technology has been developed in recent years. Chemical dust suppression agents are mainly divided into three categories: wetting agents, adhesives and coagulants; the first is the wetting dust suppression agent, generally composed of The non-polar lipophilic hydrocarbon chain part and the polar hydrophilic group are composed together. The disadvantage of using a wetting chemical dust suppressant is that the application range of the same wetting agent is small, and it may cause secondary pollution, and it does not have a strong Ability to bind dust

Secondly, the adhesive dust suppressant mainly includes organic viscous materials such as oil products, waste liquid and waste residue of the papermaking and alcohol industries; however, due to the scarcity of such dust suppressants, there are peculiar smells, and harmful components may be emitted, and Cause soil, groundwater and surrounding environment pollution, and have defects such as complex processing technology and high cost
