Description
Technical Field
The invention relates to the field of emergency disposal, in particular to an electric power emergency disposal method for dangerous chemical accidents.
Background
China has become a large country for producing and using dangerous chemicals. At present, the structure and the mode are changed from the gold development period of ten years to the adjustment, the elimination and the optimization of the layout, and the contradiction between the urban safety development and the chemical industry development is obvious. Particularly, hazardous chemical substance enterprises show the trends of regionalization, large-scale device, integration of upstream and downstream, diversification of products and the like, and the coupling risk of secondary derivative disasters or disasters is further increased. The transportation volume and the storage volume of hazardous chemicals are increased rapidly, the mixed storage situation is difficult to avoid completely, and the safety risk is increased.
The existing emergency disposal method for dangerous chemical substance accidents only considers disposal of dangerous chemical substances when the dangerous chemical substances are in accidents, and does not consider influences on peripheral equipment, particularly energy equipment when the dangerous chemical substance accidents occur. This involves the determination of the type of accident, the division of the dangerous area, the consideration of local power outages, etc.
Disclosure of Invention
The invention provides an electric power emergency disposal method for dangerous chemical accidents, which comprises the following steps:
s1, judging the accident type;
s2, evaluating the influence area;
s3, judging whether the power equipment is in the influence area, if so, entering the step S4, otherwise, entering the step S5;
s4, carrying out power emergency disposal;
and S5, finishing emergency treatment.
Further, in step S2, for the ground flowing fire, the fire affected zone is evaluated according to the leakage source condition and the terrain condition; for steam cloud explosion, evaluating an explosion influence area according to leakage source conditions, wind direction, wind speed and terrain conditions; and for toxic combustible gas leakage, evaluating a gas diffusion influence area according to leakage source conditions, wind direction, wind speed, terrain and topographic conditions.
Further, in step S4, the measures for emergency handling of power include: starting power emergency guarantee; providing guarantee for personnel in the dangerous area; it is evaluated whether a local power down is required.
Further, the starting of the power emergency guarantee comprises starting of emergency power, determination of a rescue action path, individual protection and decontamination of rescuers.
Further, the protection is provided for personnel in the dangerous area, and the protection comprises individual protection, personnel evacuation path determination, treatment and transportation measures and decontamination.
Further, if local power failure is needed, local power failure is conducted through remote control or entering a site; if the cause of the accident disappears after the local power outage, the local power supply is restored by remote control or on-site treatment, and after the power supply is restored, the process returns to step S5.
Compared with the prior art, when dealing with dangerous chemical accidents, the method considers the specific types of the dangerous chemicals and the influence areas caused by the accident types on one hand, and describes the dealing method after the electric power facilities are influenced on the other hand, so that the dangerous chemical accidents can be dealt with more comprehensively and reasonably, and the accident loss is greatly reduced.

Fig. 1 is a general flowchart of a hazardous chemical accident electric emergency disposal method.
Detailed Description
As shown in fig. 1, the emergency electric power disposal method for dangerous chemical accident includes a step S1 of determining the accident type when the dangerous chemical accident occurs, wherein the accident type is mainly based on the type of dangerous chemical and the physicochemical change; mainly comprises ground flowing fire, steam cloud explosion and toxic combustible gas leakage.
Step S2 of evaluating the affected area, for different accident types, it is necessary to scientifically evaluate the affected area according to the physicochemical rules. For example, for a ground flowing fire, evaluation is needed according to the conditions of leakage sources and terrain conditions; for steam cloud explosion, an explosion influence area needs to be evaluated according to leakage source conditions, wind direction, wind speed and terrain conditions; and for toxic combustible gas leakage, evaluating a gas diffusion area according to leakage source conditions, wind direction, wind speed, terrain and topographic conditions.
The method comprises the steps of S3 judging whether the electric power equipment is in the area according to the influence area, if the electric power equipment is not in the influence area, the electric power equipment does not need to be disposed, and the step S5 is directly transferred to emergency disposal, if the electric power equipment is in the influence area, an electric power emergency disposal step S4 is required to be carried out, for step S4, the step S401 of ① starting electric power emergency guarantee mainly comprises the steps of starting emergency electric power (such as a mobile electric power vehicle), further comprising rescue action path determination, individual protection of rescuers, decontamination and the like, ② providing guarantee for personnel in the danger area, the step S402 mainly comprises individual protection, personnel evacuation path determination, rescue transfer measures, decontamination and the like, and the step S403 of ③ evaluating whether local power outage is required, and according to the influence situation of dangerous chemical accident on the electric power equipment, local power outage measures are necessary to be taken, for example, the local power outage measures must be taken for avoiding secondary explosion of the combustible gas in a diffusion area due to the work of the electric power equipment.
If local power off is needed, the step S4031 is executed to perform local power off, and the local power off can be realized through remote control or in a field treatment mode; if the patient enters the site for treatment, main tasks such as safe regions, action paths, individual protection, decontamination and the like need to be carried out; after the local power outage, it is necessary to determine whether the accident cause disappears S4032, and if the accident cause disappears (for example, a hazardous chemical accident is controlled, a hazard source accident is completed, an electric power facility is not in an affected area, or the like), the local power supply is resumed S4033. For the power restoration, the remote control or the on-site treatment can be realized; when entering the field, the main tasks such as safe zones, action paths, individual protection, decontamination, etc. need to be performed. After the power supply is resumed, the process returns to step S5: and finishing emergency disposal.
In step S4, it should be noted that, in addition to the above three aspects, if the current emergency strength is exceeded and is not enough to cope with the accident, the external emergency cooperation needs to be performed.
In the method, the specific types of the hazardous chemical substances, the influence areas caused by the accident types and the response measures after the electric power facilities are influenced are fully considered, so that the hazardous chemical substance accidents can be more comprehensively and reasonably responded, and the accident loss is greatly reduced.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
