I. Introduction of Chlorine Gas
Chlorine gas, chemical formula for Cl? At room temperature and pressure for the yellow-green toxic gases, easy to compress, can be liquefied into a golden liquid chlorine, chlor-alkali industry, one of the main products, can be used as a strong oxidizing agent. Chlorine gas mixed with more than 5% volume fraction of hydrogen when exposed to bright light may have the danger of explosion. Chlorine can be substituted with organic and inorganic substances and addition reaction to generate a variety of chlorides. Chlorine was used as a bleaching agent in the paper and textile industries in the early days.
Chlorine is a poisonous gas, it is mainly through the respiratory tract into the human body and dissolved in the water contained in the mucous membranes, generating hypochlorous acid and hydrochloric acid, the mucous membrane of the upper respiratory tract causing damage: hypochlorous acid so that the tissues are subjected to strong oxidation; hydrochloric acid stimulates the mucous membrane to inflammatory swelling occurs, so that respiratory mucous membranes puffy, a large amount of mucus secretion, resulting in respiratory difficulties, so chlorine poisoning of the obvious symptoms of the occurrence of a violent Coughing. When the symptoms are severe, pulmonary edema will occur, making the circulatory effect difficult and causing death. Chlorine from the esophagus into the human body will make people nausea, vomiting, chest pain and diarrhea. 1L of air can be allowed to contain a maximum of 1mg of chlorine, more than this amount will cause poisoning of the human body
Two, chlorine alarm selection
In order to protect the safety of people's lives and property, so chlorine alarms are generally the range selection is 0-20ppm can be
Three, chlorine Alarm technical parameters:
Product name: ?
Chlorine alarm
Model No.: AP-G-Cl2-3
Product use environment:
Product Description: Chlorine alarm. There are chlorine alarms with display and chlorine alarms without display. The role of the product is installed in the field to monitor the real-time concentration of chlorine gas, when the concentration of chlorine gas reaches the previously set alarm value, the device will produce audible and visual alarm; at the same time, the instrument can also be detected on-site concentration of chlorine gas, converted to the corresponding standard voltage signals (eg, 0-5V), current signals (eg, 4-20mA), standard digital signals (such as bus RS485, RS232), frequency signals, Hart protocol signals, and the alarm can be used in the field of chlorine. The signals can be converted into standard voltage signals (e.g. 0.5V), current signals (e.g. 4-20mA), standard digital signals (e.g. RS485, RS232), frequency signals, Hart protocol signals, CAN2.0 bus signals, wireless signals (ZIGBEE, WiFi, nRF, GPRS), and so on, and then sent to the upper computer such as PLC, DCS, and the alarm control mainframe to carry out unified display, management and control. For the chlorine alarm with display can also be real-time display of the current detection of the gas concentration. In addition, the instrument has two internal relays (switching signals), which can control the sound and light alarms, fans, solenoid valves and other equipment.
Chlorine alarm product features:
★ National explosion-proof certification: explosion-proof type for EXd Ⅱ CT6 Gb
★ Intrinsically safe circuit design: Anpal's chlorine alarm internal circuit design are in line with the national intrinsically safe explosion-proof type.
★ Multi-function display: For the chlorine alarm with display, the device can display the concentration of the currently detected gas and the current time and other data in real time.
★ Full-featured: AP-G-Cl2-3 Chlorine Alarms are very complete in the industry in terms of power supply options, standard signal output options, range options, etc., and can almost meet your technical requirements.
★ Easy to install and use: AP-G-Cl2-3 model chlorine alarm in the installation of fixed, wiring and other aspects of the use of humanized design. Designed to stand in the field construction personnel point of view, all to facilitate the use of field construction personnel as the principle of mature products.
★ High-precision: Chlorine alarms using well-known brands of core sensor accessories, advanced hardware and filtering technology, the environment leads to error compensation technology to ensure that the device's high precision.
★ Convenient maintenance and replacement: in line with the principle of allowing customers to spend less money, but also the fastest speed to update the equipment. Ampahl chlorine alarm in the subsequent use of the product need to replace parts and maintenance, are very convenient. That will not affect the normal construction and production of customers.
★ Supporting stainless steel explosion-proof sound and light alarm: chlorine alarm is equipped with stainless steel explosion-proof sound and light alarm. There are high intensity sound and light alarm. When the site gas leakage to the alarm concentration at the same time with sound and light two timely and effective way to remind you. Let your personal and property safety can be guaranteed! Alarm value can be set by yourself.
★ Low failure rate, high stability: After years of use in the petrochemical, electric power, medical, agricultural, aerospace, mining and other environments around the world, the failure rate of chlorine alarms is extremely low. Choosing a branded instrument gives you more peace of mind!
★ With automatic calibration function: Chlorine alarms some with automatic calibration function, to reduce the detection error caused by sensor drift.
★ Communication and self-diagnostic function. The instrument can be self-diagnostic to derive the current state of the equipment operating conditions. Such as viewing, setting, calibration, alarm point setting and so on.
