Coke bottle with alcohol, showing "not passed"

Yesterday at 10 o'clock in the morning, in the Tangzi subway station security check area. A couple is holding a drink to pass the subway security . The police did not ask them to unsnap the cap and drink it as they did before. Instead, they brought the bottle closer to a black instrument and approached it with a pistol-like handle. After 3 seconds, two green words “PASS” appear on the instrument display.

This light and portable detection instrument is black, weighing about 5 kg and about 30 cm long. It consists of a handheld trigger probe and an LCD touch display. According to reports, this black instrument is a Raman explosion-type liquid finder, whose scientific name is a portable Raman detector .

This device can quickly confirm the nature of solids and liquids, such as gasoline, alcohol, hydrogen peroxide, ammonium nitrate, and explosives, on the spot, and confirm whether they belong to prohibited items as required by relevant laws and regulations. Even drugs including ice and K powder can be detected. "The detection process is very fast, basically 3 seconds to get.

The ethanol index was as high as 97.9%. According to the display details, ethanol is a flammable liquid and belongs to the category of dangerous goods stores.

However, the only inconvenience is that this instrument can only detect objects with glass, plastic, and other materials. The metal case and rugged shell detect the probe's infrared light is difficult to penetrate it, you need to sample into the test bottle inspection.

It is reported that the cost of the Raman-type explosion detection probe is as high as 350,000 yuan. "We are the first time in Yunnan Province to use the Raman-type explosive liquid probe in the subway." The police said that before that, only some major cities were in the subway. This security device was used.

New identity checker

"7 key personnel" never let go

The police officers took the black equipment and received an identity card from a citizen. After only a few seconds, they heard only a “drip” and the personal information of the citizens appeared on the screen. The following prompt “The result of the match is normal”. Yesterday, when many members of the public took the subway, they may have found that the civilian police in the security area had a slightly larger device than the mobile phone. It is reported that this instrument is called ID verification instrument , and the scientific name is portable police terminal. It takes only a few seconds to confirm the information of the person under inspection.

"If there is a criminal record, there is an instrument database." The police told reporters that if the person being checked is compared, a red box will be displayed on the display screen, and a match record will appear below. The police can know that the person to be inspected. Should be focused on personnel, there may be major criminal record.

In its system, it has entered into a database of seven key personnel of the Ministry of Public Security that need to be focused on, including those who suffer from major mental illnesses and may cause harm to the average person. "As before, the kind of instrument can not be compared in real time, but also need to manually enter the system to search for itself, it is a waste of time."

If the instrument encounters dangerous personnel related information, it can also give the police action recommendations, including "arrest, cross-examination, tracking, bring back questions, etc." In the sub-option "Inventory records", you can also find suspicious personnel The state of flight. In addition, the instrument can also record the trajectory of people entering the subway station so that the police can work.

Skid Nitrogen Generator is installed on one skid, it has compact structure, easy for ocean transportation, no need for site installation. When machine reach site,  just need to put the machine on flat ground, connect power and gas pipeline, then one simple push on starting button makes the Nitrogen Generator begin to work. It normally includes Air Compressor , air tank, dryer and filters, also the key part, nitrogen separator. At the end of plant, there is one nitrogen buffer tank. This tank is also needed by the Nitrogen Generation process.


Standard Nitrogen Generator has skid structure, therefore they are also called skid nitrogen generator. Its basic specification is as below:

Flow rate: 5-3000 Nm3/hr

Purity: 90-99.9995%

Outlet pressure: 5-10 bars
