[ Hot Focus of Chemical Machinery and Equipment Network ] In recent years, due to the rapid economic development, the phenomenon of urban compound air pollution has intensified
.
The main sources of compound pollution are: production pollution, such as harmful substances emitted from fuel combustion, smoke and dust generated by coal consumption in domestic stoves and heating boilers, sulfur dioxide and other harmful gases; transportation pollution, such as motor vehicle exhaust
.
Therefore, air pollution control is imperative, and relevant equipment is indispensable
.

Chemical machinery and equipment network hotspots focus on chemical machinery and equipment

In the next five years, air pollution control will still be the key direction of environmental protection in China, and the "string" of industrial flue gas control is still being further tightened
.
In addition, while the thermal power industry market tends to mature, the flue gas control work in non-electrical industries, such as steel, coking, cement, glass and other industries, will open up a considerable market
.

Recently, under the guidance of China Environmental Protection Industry Association, the "2021-2030 Air Pollution Control Industry Development Prospect Report" edited by Longjing Environmental Protection was officially released, which analyzed the development status and trends of my country's air pollution control industry in detail:

According to incomplete statistics, the scale of air pollution control in China in 2019 is about 260-280 billion yuan
.
In various sub-sectors, industrial flue gas treatment accounts for the majority, including thermal power industry and non-electrical industries such as steel, coking, cement, glass, and waste incineration, followed by VOCs treatment, vehicle exhaust treatment, indoor pollution and oil fume treatment
.

In order to strengthen the monitoring and control of air pollution, China has built an environmental monitoring air station.
Its main equipment includes online ion chromatography, heavy metals, OC/EC (organic carbon/elemental carbon), single particle time-of-flight mass spectrometer, and VOCs (volatile organic compounds).
), black carbon, turbidity, aerosol lidar, wind profiler radar, microwave radiometer, etc.
, mainly to review and analyze data such as particulate matter and VOC
.

In addition, for productive pollution, a continuous monitoring system for flue gas emissions can be used, including gas analyzers; particulate matter analyzers; temperature, pressure, flow rate monitors and other instruments and equipment
.
It is suitable for the monitoring of continuous exhaust gas emissions of various boilers, continuous online monitoring of particulate matter concentration, sulfur dioxide (SO2) concentration, nitrogen oxide (NOX) concentration, oxygen (O2) content, flue gas temperature, flue gas pressure, flue gas flow rate , can also increase the measurement of carbon monoxide (CO), carbon dioxide (CO2), hydrogen chloride (HCL), hydrogen fluoride (HF), ammonia (NH3), hydrocarbons (CHX), humidity and other parameters
.

It should be noted that in the past ten years, driven by policies such as the "Comprehensive Implementation of the Work Plan for Ultra-Low Emission and Energy-Saving Transformation of Coal-fired Power Plants", the flue gas control of the thermal power industry has achieved remarkable results
.
By the end of 2019, a total of 86% of coal-fired power units have been retrofitted with ultra-low emissions across the country.
The technology, equipment and market are all mature, and there is limited room for future growth
.

　　In the next stage, the industrial flue gas treatment market will focus on non-electrical industries
.
Among them, the iron and steel and coking industries are already in a mature stage, and industries such as cement, glass, and waste incineration are ushering in stricter air pollution control standards and ultra-low emission transformation requirements.
The market demand is accelerating and is in a growth stage
.

　　For transportation pollution, the use of relevant instruments and equipment to detect vehicle exhaust is a very important means to control vehicle exhaust pollution
.
The vehicle emission detection instrument is an instrument to detect the emission status (concentration) of vehicle exhaust, mainly including: vehicle exhaust gas tester, diesel vehicle exhaust gas analyzer and other instruments and equipment
.

Detector

　　The editor learned that for the monitoring of air pollutants, there are also flue gas analyzers, toxic and harmful gas monitors, atmospheric heavy metal online analyzers, carbon monoxide analyzers, carbon dioxide analyzers, air detectors, haze monitoring systems, air quality Gas detection instruments such as automatic monitoring systems
.

Instrumentation

　　And in 2030, China will also achieve the goal of carbon peaking as scheduled.
In this context, the non-electricity industry will also face the pressure of carbon emission reduction
.

　　At the beginning of 2021, the top-level design document of the "14th Five-Year Plan" was issued, which clearly put forward a binding target of reducing carbon emissions per unit of GDP by 18%, and supported qualified places, key industries and key enterprises to take the lead in reaching the peak carbon emissions
.
Subsequently, the "Regulations on the Administration of Pollution Discharge Permits" issued by the State Council further forced high-polluting industries to carry out emission control through monitoring, filing and other means
.

　　In addition, the standards for non-electrical industries, especially cement, glass, etc.
, are constantly tightening
.

　　For example, recently, the "Sichuan Province Cement Industry Air Pollutant Emission Standard" was issued, and it has been implemented since July this year.
It is required to increase the pollution reduction of the cement industry and solve the problems of inadequate management of unorganized emissions, overloaded production, and ammonia escape.
Fully measure the four aspects of objective science, technical feasibility, economic rationality and operational feasibility
.

　　Jiangsu Province will also implement the "Cement Industry Air Pollutant Emission Standard" in July this year.
The second stage of the local standard requires that the emission of dust, sulfur dioxide and nitrogen oxides from the cement industry should not be higher than 10, 35, and 50 mg / Cube, more strict
.

　　At the national level, the "14th Five-Year Plan for Industrial Green Development" clearly requires: to further promote the ultra-low emission transformation of the iron and steel industry, and to steadily implement ultra-low emission transformation of cement, coking and other industries
.
By 2025, complete the ultra-low emission transformation of 530 million tons of iron and steel production capacity and the clean production transformation of 460 million tons of coking production capacity; promote the transformation of process technologies and equipment such as desulfurization, denitrification and dust removal ultra-low emission in the cement industry, and furnace flue gas dedusting in the glass industry
.

　　The above-mentioned report pointed out that the control of air pollution in the next five years will still be the key direction of environmental protection in China
.
From 2021 to 2025, the flue gas control work in the non-electricity industry mainly lies in the replacement of production capacity, the flue gas control of relocation and the unfinished ultra-low emission transformation; from 2026 to 2030, it will turn to the secondary transformation of ultra-low emission transformation
.

　　And according to estimates, the market capacity of the industrial flue gas treatment industry in 2021-2025 can exceed 400 billion yuan
.
Among them, third-party operation and maintenance will gain a considerable share, and related monitoring, monitoring systems and other environmental monitoring equipment will also enter the fast lane of development
.

　　For the prevention and control of air pollution, monitoring instruments play an important role in it, and assume the responsibility of providing accurate monitoring data and monitoring reports, and its importance is beyond doubt
.
As the whole society attaches importance to pollution problems, the demand for environmental monitoring instruments has increased significantly
.
