Technology blessing!Copy ozone pollution, Xi'an "has a trick"

Busy robot

The spray workshop that can't smell the odor

Super factory allows harmful gases to "zero emissions"

Small machines let pollutants have nowhere to hide ...

Recently, the reporter followed the environmental protection law enforcement officers into key enterprises, auto repair enterprises, gas stations, etc., and experienced the city's continuous use of scientific and technological means, actively cope with ozone pollution, retain the "good temperament", and fight ozone pollution prevention. Various "artifacts".

Visiting "Xi'an Super Intelligent Environmental Protection Factory"

The reporter followed the law enforcement officer to the Geely Automobile Xi'an manufacturing base known as the "Xi'an Super Intelligent Environmental Protection Factory". In the painting workshop, there was no one in the large room. Only robots were sprayed in an orderly manner. Any pungent smell of organic gas.

"Our noodle paint uses water -based process, and VOCS (volatile organic) emissions are reduced by 30%compared to traditional crafts." According to Li Jicheng, deputy director of the coating factory, after using the robot to achieve full automatic surface spraying, artificial operations will be reduced. Use 10%noodle paint materials.

During the on -site observation, the reporter noticed that the white ceiling in the plant was laid on the white filter cotton. Where did the most headache and volatile organic matter went? Before coming to the outdoor RTO platform, Li Jicheng pointed at the complicated coarse pipeline of the curved and said that the volatile organic matter generated during the spraying process was pressed to the bottom of the workshop and sent it to the exhaust gas incineration furnace through these pipes. Usually the temperature of the incineration furnace can reach 800 ° C. When the gas is cracking, the factory will reuse the high -calorie gas, just like heating rooms, to achieve the purpose of energy saving and consumption. At the same time, volatile organic matter can be discharged through the chimney of up to 55 meters high after forming carbon dioxide and water at the end. In addition to a wonderful recruitment of VOCS, this "super factory" also has a green area of ​​296,000 square meters. It has 29 trees. The manufacturing cycle can achieve the "thirty zero" of zero waste water discharge, zero waste landfill, and zero harmful discharge. Green cycle.

"In order to thoroughly fight pollution prevention and actively cope with ozone pollution, since the summer, we have increased the supervision and assistance of air quality in key areas." Zhou Chonglong, the head of the Evaluation Division of the Comprehensive Law Enforcement Detachment of Xi'an Ecological Environmental Protection In order to strengthen the help guidance service law enforcement, the cross -examination team passed the "physical examination" inspection on the spot, listed one by one on the problems of the enterprise, carefully explained the requirements of daily supervision, helping enterprises solve the problem of pollution governance, and give full play to the help of assistance. By sending policies, technology, and services to enterprises, it is necessary to relieve difficulties for enterprises; clearly rectify the period of rectification of the problems found, implement special personnel to follow up, and guide enterprises to rectify targetedly to ensure that rectification is in place.

Black Technology supports small machines

Test summer pollutants

According to reports, the previous VOCS on -site law enforcement inspections have limitations. For example, during the on -site inspection, "I can't see it", it is difficult to distinguish the odor and VOCs, and the leakage point and concentration judgment mainly depends on experience. Nowadays, under the blessing of law enforcement monitoring equipment, the law enforcement work of pollution in summer has been "added".

On August 8th, at a gas station in Lianhu District, the staff of the Atmospheric Office of the Municipal Ecological Environment Bureau was checking the oil -removing ledger, oil and gas recovery device, and sealing. In the meantime, inspectors took out a small -volume and SLR camera, saying that this is called infrared gas camera. If the oil and gas volatilize or the oil gun leaks, there will be smoke display on the display screen.

In front of the gasoline ventilation pipe outside the gas station, the reporter observed that there was no abnormality in the naked eye, but when the staff observed with an infrared gas camera instrument, a trachea was found to be smoking outward. "This shows that organic matter is volatilizing." The staff said that the hotter the weather, the faster the volatilization, the more obvious from the machine.

"Now there are small auto repair companies hidden in the alley. It is difficult to find out whether there are violations of regulations, but observing through infrared gas camera device, if this kind of flue gas appears, it means that there is an organic matter volatilization." The personnel said that in this way, just follow the picture to find the auto repair enterprise that is illegal.

In addition, the palm -holding hand -held volatile organic gas analyzer is also "full of power". As long as it is close to the exhaust port of the volatile organic matter, the concentration of pollutants will be displayed in real time. This is easier and intuitive than previous law enforcement officers judging by experience, and the test results are more convincing.

It is understood that in this year's summer key areas, the ecological environment staff of our city, together with the "one city, one strategy" expert, through on -site law enforcement, make full use of high -tech means to ensure that the problems should be found and discovered. Relying on infrared thermal imaging, portable FID detectors, PID detectors, wind speed instruments and other high -tech equipment, comprehensively use VOCS flights, laser radar scanning, drone cruise and other technology means to accurately investigate the source of pollution, further increase the technology Treatment of haze and accurate haze.

Continuously advance

Ozone pollution prevention and control battle

With 2022, the air quality supervision and assistance work in key areas in 2022 as the starting point, our city will continue to advance the battle against ozone pollution prevention. The comprehensive law enforcement detachment of Xi'an Ecological Environmental Protection has selected the city's backbone law enforcement forces, focused on the fields of key industries, accurately imposed policies, pulled the pulse of corporate environmental protection, and promoted the rectification of corporate environmental issues.

The joint law enforcement adopts the working model of "law enforcement+monitoring+expert", led by the comprehensive law enforcement detachment of the Xi'an ecological environmental protection to regulate the backbone law enforcement forces in the district and county, invite experts to jointly test the company to comprehensively dig out the issue of VOCS emissions in key industries. Essence Summon experts and relevant municipal departments every week to conduct business and control scheduling for air quality research and judgment, to report centralized reports, resolve them in a timely manner, and arrange work in the next week. As of now, the assistance and guidance work has invited experts to provide precise assistance in air pollution control in 135 key industries in the city; helping 130 enterprises in the city has helped and found 284 problems. In terms of comprehensive remediation in key areas, the Municipal Commerce Bureau has organized 540 gas stations in the city to complete self -inspection in accordance with the relevant plan of the relevant plan. A total of 12 problems were found and 12 rectification was completed. The Municipal Ecological and Environment Bureau and the Municipal Commerce Bureau inspected 32 gas stations. In addition to fewer gas stations, 26 companies with different problems have been transferred to the Municipal Bureau of Commerce for investigation and punishment.

In addition, the Municipal Transportation Bureau formulated and issued the "Special Action Plan for the Prevention and Control and Control of Ozone Pollution in the Transportation Industry in 2022", and 38 auto repair enterprises have been supervised. The Municipal Housing and Construction Bureau printed 5,000 "Construction Site Volatile Organic Prevention Knowledge" publicity page, organized a video conference on "Summer VOCS pollution prevention and training", requiring housing and construction departments at all levels to strictly implement the "Xi'an Construction Construction City Construction "Special Action Plan for the Prevention and Control of Summer Volatility of Organic Pollution in the Field" requirements, increase the frequency of inspection, and do a good job of propaganda and guidance of ozone pollution prevention.
