Application Scheme of Gas Detector in Coking Coal Metallurgy Industry

Background of the project

Coal coking is an important chemical process in the metallurgical industry. The main processing method is high-temperature coking to extract useful chemical products and recover combustible gases. The chemical products produced in the coking process can be recovered, treated and processed to obtain coke oven gas, coal tar, benzene, toluene, xylene, naphthalene, ammonia, hydrogen sulfide, carbon disulfide, etc. These products are the chemical industry, medicine An important raw material for industry.

In recent years, occupational benzene poisoning accidents in my country have mostly occurred in shoemaking, luggage, toys, electronics, printing, furniture and other industries, mostly caused by benzene-containing adhesives, thinners, hardened water, detergents, boiling oil, paints, etc. Benzene is a colorless, transparent, aromatic, and volatile toxic liquid. It is a product of coal tar distillation or petroleum cracking. It can volatilize at room temperature and form benzene vapor. The higher the temperature, the greater the volatilization.

dangerous gas

Benzene mainly enters the human body in the form of vapor through the respiratory tract. Short-term inhalation of high-concentration benzene vapor and long-term inhalation of low-concentration benzene vapor can cause physical damage to workers. Short-term inhalation of a large amount can cause acute mild poisoning, manifested as headache, dizziness, cough, chest tightness, excitement, and staggering gait. At this time, if the inhalation is continued, severe acute poisoning may develop. The patient's mind is blurred, blood pressure drops, muscle tremors, breathing is shallow and fast, and pulse is fast and weak. Rescue in time can restore health after hours or days, but severe cases can also die due to paralysis of the respiratory center.

Program overview

In order to fully protect the environmental safety in the factory area, a toxic gas detection system should be installed to monitor the factory buildings, laboratories, warehouses, etc. in real time. When a certain gas content exceeds the standard, timely measures should be taken to avoid danger.

1. On-site gas monitoring solution

The Detector can continuously monitor the measurable gas in the industrial environment, and convert the gas concentration into a digital signal, which is transmitted to the gas alarm controller, which is identified, displayed and processed by the controller. When the index of a certain gas to be tested on site exceeds or falls below the set standard, the controller system will automatically perform a series of alarm actions, such as alarm, exhaust, trip, etc. (varies according to different settings of the user).

2. Data transmission scheme

YC-G data remote transmission terminal is a new type of terminal equipment for collecting sensor data with high flexibility and high reliability that our company has carefully researched and developed on the basis of summarizing the design and production experience of many years of data collection equipment. .

The device can be widely used in fixed Gas Detectors and gas control cabinets supporting the modbus protocol. Real-time monitoring of on-site gas concentration, real-time collection and transmission of various data. Through the 485 communication line and the detection equipment connection, the concentration value, decimal point, unit, equipment status and other information can be read in real time, and uploaded to the company's data monitoring server center according to the set time interval.

3. Terminal system solution

Baoshian industrial gas online monitoring platform uses new technologies such as the Internet of Things, cloud technology, big data, and mobile Internet as means to realize real-time gas data reporting, remote control, and equipment management, so as to realize the detection of dangerous gas leakage in the monitoring area. Event monitoring and prompting and alarming can effectively prevent the occurrence of dangerous accidents in enterprises, realize gas leakage and management in the production process, and ensure safe production of enterprises.

Managers can check the real-time values ​​of monitoring area parameters at any time through computers, mobile phones, tablets, etc. When the relevant parameters exceed the limit, an alarm message will be issued to remind the manager to take corresponding measures, and control instructions can be sent to the relevant equipment through the computer or smart phone to realize the remote control of the gas parameters in the monitoring area.

System Features

1. Comprehensive remote monitoring of flammable and explosive gas content changes;

2. Predict the trend of change;

3. Realize safe production and achieve sustainable business growth.
