Description

Early warning system for detecting environmental anomalies

The present invention is related to an early warning system, in particular to an early warning system for detecting environmental abnormalities.

Dust combustion refers to the rapid burning of combustible dust particles suspended in a closed or confined space or outdoor environment. If in a closed environment, combustible particles or confined in the atmosphere or oxygen molecules and other suitable gaseous media have a sufficiently high dispersion concentration, the dust An explosion may occur.

In the manufacturing process of various industrial products, many manufacturing procedures and processing steps will generate dust, and accompanying generation of volatile organic compounds, which cause air pollution and severely affect the surrounding environment. The generation of dust and volatile organic compounds can cause air pollution and harm In addition to ecology, it can also cause explosions in severe cases.

Here are the most significant examples:

In February 1999, a fatal fire and explosion occurred in a foundry in Massachusetts. The U.S. Occupational Safety and Health Administration and state and local governments conducted a joint investigation into the accident. The joint investigation report pointed out that the fire was caused by an unknown ignition source igniting the shell mold casting machine, and then a large amount of deposited phenolic resin dust material was poured into the casting machine and spread to the duct of the ventilation system. A small initial deflagration occurred before the inside of the duct, and the dust began to settle outside the duct. The ensuing dust cloud became the fuel required for the second explosion, and the power of the second explosion was enough to lift the roof and cause wall damage.

In January 2003, a devastating fire and explosion destroyed a pharmaceutical factory in North Carolina producing synthetic rubber drug delivery elements, causing the unit to produce volatile organic compounds, causing air pollution, and severely affecting the surrounding environment. 6 employees were killed and 38 people were injured, including 2 firefighters. The American Chemical Safety and Hazard Investigation Commission, which is an independent federal agency responsible for investigating chemical accidents, published the final report and concluded that flammable polyethylene dust accumulated on the ceiling and caused an explosion.

In February 2003, another fatal dust explosion occurred in a sound insulation cotton manufacturing plant in Kentucky. CSB also investigated the accident, and its report pointed out that the possible cause of the ignition was that a small fire spread from an unnoticed stove, which ignited the dust cloud generated by the cleanup operation of the nearby production line, and then a lethal dust explosion. Successively occurred throughout the entire plant.

In containers or buildings, metal dust scattered in the air may also explode. In October 2003, an accident occurred at an automobile tire manufacturing plant in Indiana, and CSB was also investigating the accident. Although the investigation report has not been released, CSB’s press release reported that the accident process is similar to the previously described organic dust accident: the first explosion occurred near the fragment melting furnace, and aluminum powder participated in the first explosion, and then the dust collection equipment occurred. Second explosion.

And the basic elements of dust explosion: First, combustible dust (fuel); Second, the ignition source (heat energy); Third, oxygen (oxidant) in the air; Fourth, the dust is dispersed in the gas phase with sufficient amount and concentration; and Fifth, limited combustible dust.

Add the last two basic elements to the fire triangle (that is, the famous explosive pentagon, as shown in Figure 1A. If the dust cloud is ignited in a confined space or a semi-confined container, area or building, it will quickly It burns and may explode. The life safety of employees will be threatened by the ensuing fire, explosion, flying fragments and collapsed building elements.

When a dust cloud is ignited in a confined or semi-confined space, it will burn rapidly and produce an explosion. The airflow generated by the first dust explosion will raise more deposited dust and cause a second dust explosion, as shown in Figure 1B Show. The characteristics of a comprehensive dust explosion can be summarized as follows:

The first point: During the first dust explosion, the dust may not be completely burnt and consumed, and more deposited dust will be raised and secondary or multiple dust explosions will occur, because the amount and concentration of dust ignited by the secondary dust explosion are usually higher. Therefore, the power of the explosion is stronger than that of the first dust explosion.

The second point: Although the minimum ignition energy required for a dust explosion is higher than that of a combustible gas explosion, the smaller the particle size of the combustible dust, the smaller the minimum ignition energy and the higher the explosion pressure.

The third point: the reaction time of dust explosion is dozens of times that of general combustible gas explosion.

The fourth point: Compared with combustible gas explosion, dust explosion pressure rises more slowly, but the pressure lasts longer, the energy released is greater, and the destructive power is stronger.

Fifth point: Dust explosions may produce carbon monoxide and toxic gases produced by high-temperature decomposition of explosive materials (such as plastics, etc.).

When free dust accumulates in the process equipment or area, after the initial explosion, more accumulated dust may be loosened or the surrounding system (such as ducts, containers or dust collectors) may be damaged. It will cause extra dust to be dispersed in the air. If it is ignited, it will cause one or more secondary explosions. Also because of the higher amount and concentration of dust dispersed, it has a stronger destructive power than the first explosion. .

In addition, in addition to the danger of explosion, the concentration of dust is sufficient to affect various parts of the human body, especially the skin, eyes, nose, throat, respiratory tract and lungs. Therefore, in addition to self-protection, the most important thing is to be able to In the shortest time, the dust and volatile organic compounds can be prevented and dissipated. In other words, in the production process of various industrial products, the generation of dust and the accompanying production of volatile organic compounds are unavoidable, but as long as the prevention and control is in the process Proper handling can still minimize the damage of dust and volatile organic compounds to the human body and the surrounding environment, or even no harm at all.

Dust types: there are two kinds of mineral dust and non-mineral dust. Non-mineral dusts are animal dusts or plant dusts. Inhalation may cause allergic asthma. However, after staying away from the allergen, the symptoms will usually reduce or disappear; mineral dusts include metal fume, free silica dust, and asbestos Dust, other offensive dust, metal fume can cause chemical pneumonia, free silica dust can easily cause pneumoconiosis of pulmonary fibrosis, and asbestos dust can cause mesothelioma. As for whether dust easily enters the human body, it is related to its particle size. Generally speaking, it is called inhalable dust with a particle size below 100 µm, thoracic dust below 10 µm, and respirable dust below 4 µm. Among them, respirable dust has the smallest particle size. Deep and deposited in the lungs, it is the most harmful to health.

In addition, ignite the gas in the air, the gas may detonate, or it will stop quickly, this situation is determined by the concentration of the gas in the air. When the gas concentration is too low, there is not enough fuel to sustain the explosion; when the gas concentration is too high, there is not enough oxygen to burn. The gas can only detonate between two concentrations. These two concentrations are called the lower explosion limit and the upper explosion limit. It is generally used to express in percentages, which are the explosion limits of the gas.

Here are the most significant examples:

On April 7, 2019, the third aromatic hydrocarbon plant of Taiwan Chemical Fiber Co., Ltd. (hereinafter referred to as Taihua) in the Sixth Light Industrial Zone of Formosa Plastics Corporation, located in Mailiao, Yunlin, Taiwan, made a huge explosion and emitted thick smoke. As far as the blast hit, even houses five kilometers away felt the shock. The Formosa Plastics Corporation immediately issued a statement stating that the leakage of the corroded perforation of the LPG pipeline caused the rupture of the butane tower and caused a fire.

A benzene tank explosion occurred at the Tianjiayi Chemical Plant in Xiangshui County, Yancheng City, Jiangsu Province. The Jiangsu Provincial Department of Ecology and Environment claimed that the volatile organic compounds of chloroform, dichloromethane, dichloroethane and toluene were detected in the gates of three rivers nearby. Among them, the highest concentration is the section inside the Xinfeng River Gate. The concentrations of toluene, dichloroethane and dichloromethane are 204 micrograms/liter, 114 micrograms/liter and 187 micrograms/liter, respectively. Dichloroethane and dichloroethane The methane is 2.8 times and 8.4 times higher than those stipulated in China's "Surface Water Environmental Quality Standards" respectively.

Therefore, how to solve the above-mentioned problems and deficiencies is the direction that the creators of the present invention and related industries engaged in this direction urgently want to study and improve.
