Laboratory hazardous chemical substance cabinet

Abstract

The invention discloses a laboratory hazardous chemical substance cabinet which comprises a cabinet body, a rotating door body is arranged on the front face of the cabinet body, a vertical partition plate is arranged in the cabinet body, and the vertical partition plate divides the inner space of the cabinet body into a storage area and a functional area; a plurality of placing plates are arranged in the storage area in parallel up and down; a temperature sensor, a humidity sensor, a volatile organic compound (VOCs) sensor and a control device are arranged in the functional area; a temperature on-line alarm, a humidity on-line alarm and a VOCs on-line alarm are arranged outside one side, close to the functional area, of the cabinet body; the vertical partition plate and the placement plates are hollow plates; and a waste gas outlet is formed in a back panel of the cabinet body and is connected with a waste gas outlet pipe. According to the hazardous chemical substance cabinet, the temperature, the humidity and the VOCs environment in the hazardous chemical substance cabinet can be monitored online in real time, so that hazardous chemical substances stored in the cabinet are in strict environmental conditions, the performance of the hazardous chemical substances is prevented from changing, and temporary storage and use safety of the hazardous chemical substances is ensured.

Description

technical field [0001] The invention relates to the field of laboratory supplies, in particular to a hazardous chemical cabinet for laboratories. Background technique [0002] In order to strengthen the safety management of hazardous chemicals, ensure the smooth progress of teaching and scientific research, protect the life and property safety of researchers, and protect the environment, the State Council has formulated the "Regulations on the Safety Management of Hazardous Chemicals". Among them, the scope of management of hazardous chemicals: including explosives, compressed gases and liquefied gases, flammable liquids, flammable solids, spontaneous combustion and flammable materials when wet, oxidants and organic peroxides, poisonous and corrosive products, radioactive substances Isotopic items, etc. [0003] The hazardous chemical cabinet is a special storage cabinet for hazardous chemicals, which greatly reduces various safety hazards caused by the dangerous properties...

AI Technical Summary

Problems solved by technology

However, the structure of the existing hazardous chemical cabinets is relatively simple, and most of them only serve the purpose of storing hazardous chemicals, and do not have the function of real-time monitoring of environmental conditions such as temperature, humidity, and VOCs in the hazardous chemical cabinets; Most of the chemical cabinets are in a closed environment. When storing volatile hazardous chemicals, the content of harmful gases such as organic and inorganic waste gases in the cabinet will be high. When the staff opens the cabinet door again, the odor is heavy and pollutes the laboratory. The environment directly affects the health of the
