Technical knowledge of purge ship exhaust cleaning system

Technology research and development

The Puyi ship waste gas washing system is a new high-tech product with independent intellectual property rights. It has more than twenty domestic patents and 3 international patents. It has been approved by CCS, BV, LR, ABS, DNV GL and NK six major classification societies.

The ship exhaust gas treated by Puyi ship exhaust gas cleaning system fully meets the most stringent 0.1%m/m sulfur emission standard stipulated in the MARPOL convention.

By virtue of the superior technological route and the gas and liquid flow distribution device that meets the design of fluid mechanics, the purge ship exhaust cleaning system has a greater advantage over the volume, weight and operating cost of the foreign products.

Technology maturity

The washing system technology is mature and has many applications in the environmental protection industry. In order to meet the environmental protection needs of the marine industry, the desulfurization process is further optimized, and the reliability and practicability of the technology are verified through a pilot test, a pilot test and a ship test.

Simple and reasonable structure of equipment

On the basis of satisfying the washing effect, the equipment structure is simplified, the weight of the equipment is reduced, and the resistance drop of the equipment is reduced.

Flexible operation, reasonable reduction of consumption

The linkage between consumption and load can be realized by establishing chain control of operation parameters and frequency adjustment of power equipment, so as to reduce operation cost.

High degree of automation

The main control parameter signals are connected to the PLC system, equipped with automatic feeding system, chain regulation, operation signal, operation load automatic adjustment, fault alarm, etc.

Flexible installation

According to the actual ship surveying and mapping flexible design, layout, easy installation.

Environment-friendly

After washing, the sea water is filtered and discharged without causing pollution. During filtration, a small amount of solid slag is produced. Temporary storage of waste residue tanks and shore based treatment will not cause two pollution to the marine environment.

Investment recovery period

The investment recovery period is short: analysis shows that if the ship 50% is sailing in the emission control area, the investment recovery period of Puyi ship exhaust gas cleaning system is about 1.3 years.
