Shanghai shipbuilding industry takes the lead in promoting the application of water-based coatings

Entering the autumn and winter seasons, the air quality every day affects people's nerves.

"Shanghai Hulin Heavy Industry Co.
, Ltd.
chose a middle road.

"Led by Hudong Heavy Machinery Co.
, Ltd.
, its subsidiary Shanghai Hulin Heavy Industry Co.
, Ltd.
, and domestic well-known colleges and universities jointly undertook the research "Large-scale coating process volatile organic compound (VOCs) processing key technology integration and demonstration project" has been in 2017 It passed the mid-term review of the Shanghai Science and Technology Commission on August 22, 2010.
According to Wang Min, general manager of Shanghai Lin Heavy Industry, after more than half a year, the three parties have jointly developed a new type of adsorption concentration + catalytic combustion technology, and developed a VOCs treatment integration Test devices 1.
0 and 2.
0 have formed an integrated solution of "VOCs efficient collection-paint mist effective treatment-VOCs efficient purification", and the VOCs treatment effect has reached and exceeded the expected indicators.

In the paint shop of Shanghai Linhe Heavy Industry Co.
, Ltd.
, the VOCs processing integrated test device 2.
0 is operating stably.
The display indicates the import concentration, pre-filtration concentration and outlet concentration of the processing equipment.
The larger test device 1.
0 has completed its historical mission.
.
Li Xiaodong, the person in charge of the project, said that the VOCs treatment in the paint shop of the shipyard has the characteristics of unbalanced load, large exhaust volume, and high operating cost.
For these, Hulin Heavy Industry has selected a new type of VOCs adsorption material, which can withstand higher temperatures and has a long service life.
More than 5 years; in view of the extremely high VOCs concentration in the paint shop of the shipyard for 4-6 hours a day, the secondary filtration and load buffering technology are used to smooth the wave peaks and greatly improve the efficiency and use of the subsequent treatment devices life.
At the air inlet, in response to the large amount of paint mist contained in the exhaust gas, Hulin Heavy Industry has developed a new type of paint mist filter device with self-cleaning function, which has zero consumables, zero hazardous waste, and has the effect of unobstructed exhaust.
The test device 2.
0 uses fluid mechanics calculation simulation technology to realize the optimal distribution of air volume.
In the high-load operation section, the high-volume air supply and exhaust scheme is selected; in the low-concentration volatilization stage without personnel participation, the intelligent air supply scheme with small air volume is selected.
In addition, the equipment also uses waste heat recovery and reuse technology, which greatly reduces operating costs; using integrated and automated control technology, it can achieve 24-hour full-process monitoring and unattended operation.

Shipyards in Shanghai, which are fighting against VOCs, are facing many uncertainties in policies and technical routes, but they are taking firm steps to fulfill their corporate social responsibilities and explore optimal governance solutions.
With the spread of VOCs governance across the country, I believe these explorations and entanglements are worthwhile.
