Description
Technical Field
The utility model relates to a safety in the grain warehouse management field of producing, it is particularly related to one kind and applies to the dangerous gas real-time supervision early warning control system in grain depot.
Background
The grain safety is the foundation of national safety and the strong guarantee of the nation. On the grain safety problem, besides ensuring the quantity by adhering to the red line of cultivated land, protecting the enthusiasm of farmers for grain planting and improving the grain planting efficiency by means of science and technology, the grain delivery loss reduction and quality guarantee are also key links for realizing effective supply of grains. At present, the preservation technologies commonly used in the grain storage link mainly include ventilation, refrigeration, capping, air conditioning, fumigation and the like. The application of the fumigation technology is mainly to fill a fumigant with a certain concentration into a grain stack under a closed condition to achieve the purpose of killing stored grain pests and ova. The fumigant is an insecticide which enters a pest body in a gaseous state through the respiratory system of the pest to exert an effect. Phosphine is a high-efficiency fumigant for preventing and controlling pests in stored grains in the world at present, is also one of the main insecticides commonly used in grain stores in China, and can be generated by aluminum phosphide, calcium phosphide or zinc phosphide through different chemical reaction ways. Aluminum phosphide and calcium phosphide generate phosphine by absorbing water vapor in air, and zinc phosphide generates phosphine by reacting with an acid or alkali solution. Although phosphine works very well as a fumigant, the acute toxicity also risks harm to the human body. If entering into pulmonary alveoli through respiratory tract, it will cause congestion and edema of respiratory tract, and if entering into blood, it will reach various systems, organs and tissues along with blood circulation, mainly damaging central nervous system, heart, liver, kidney, etc., and when the phosphine in air reaches a certain concentration, it will cause death. Therefore, the fumigation operation has very strict operation rules and must be performed by personnel who have been trained, know the performance of the medicament, and master the fumigation technique and the method of using the gas mask. However, phosphine is generated during the fumigation operation, and phosphine gas is slowly released during the storage process of various phosphide in a drug library. In addition to phosphine, a major hazardous gas to be monitored, other agents stored in drug depots may also be lost. If the safety production management of dangerous reagents and gases in a drug library is neglected in daily warehouse management to form a great potential safety hazard, production accidents are likely to happen, and the life safety of personnel is greatly threatened.
In order to ensure the safety of grain storage and the safety of grain depot production, the national food service promulgates temporary regulations on the safety responsibility of grain and oil storage, the rules of conservation of grain and oil storage, and the rules of conservation of grain depot production, namely the rules of conservation and conservation of both regulations of the grain system. Regarding the management of the grain depot and drug depot, the regulations in the grain depot safety production rules strictly execute five pairs of chemical agents (double receiving and dispatching, double reception, double taking, double keeping, double locks and double book accounts), the drug depot is provided with an explosion-proof exhaust fan and an explosion-proof lamp, a person opens the exhaust fan before entering, wears a safety protection appliance, and detects the concentration of harmful gas by using a portable alarm. If strictly in accordance with the requirements of rules of law, the related staff of the drug library can be effectively protected, but there are some points which are difficult to control in the operation. For example, how long the drug storage door should be opened for harmful gas concentration detection. The problems of the prior art include that the ventilation time cannot be profoundly specified due to various uncertain factors such as drug depots with different volumes, phosphide storage with different dosages, phosphine generation rate under different environmental temperatures and humidities, and ventilation volume of different ventilation devices. However, the uncertain ventilation time may cause two situations, one is insufficient ventilation, and when the door is opened to detect the concentration, related personnel have certain danger, and the other is too long ventilation time, which wastes time and increases energy consumption. If the staff does not strictly perform the rule before entering the drug library, more serious consequences may be caused.
