Embodiment Construction

[0015] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0016] figure 1 The example of the exhaust gas purification device for marine diesel generator sets is shown. The diesel engine power of this example is 3900kw and the displacement is 220000m. 3 / h. Due to the large power of the matching diesel engine, it is large in size and heavy in weight. Such a large-scale marine diesel generator set exhaust gas purification device must be installed in the engine room. In order to facilitate management and operation, an automatic control mode is adopted, and its components include diesel oil. Generator set 1, flue 2, bypass valve 3, pressure switch 4, switch valve 5, PLC module 6, outlet valve 7, catalytic oxidation device 8, ceramic filter 9 and fan 10. The diesel generator set 1 utilizes a flue 2 to discharge exhaust gas, and a room-pass valve 3 is arranged in the flue 2, and this structure con...

Abstract

The invention discloses a tail gas purification device for a diesel generator set for a ship. The tail gas purification device comprises the diesel generator set, a flue, a bypass valve, a pressure switch, a switch valve, a PLC module, an outlet valve, a catalytic oxidation device, a ceramic filter and a fan. A valve control type tail gas straight exhaust passage is formed by the flue and the bypass valve. The two ends of the bypass valve are connected in parallel with a tail gas purification channel formed by sequentially connecting a switch valve, a catalytic oxidation device, a ceramic filter, a fan and an outlet valve. Due to the fact that a double-purification structure is arranged in the tail gas purification channel, namely a front chemical purification structure and a rear physicalpurification structure, the function complementary purification structure is simple, the operability is good, and the purification efficiency is high. In addition, the working environment temperatureis higher than the dew point of the tail gas, and no wastewater is drained in the purification process, so that the configured flue has no water corrosion problem, and the particulate matters obtained after filtration can be recycled. The tail gas purification device is particularly suitable for ships with ocean navigation.

Description

technical field [0001] The invention belongs to a technical solution in the technical field of environmental protection devices, in particular, the invention relates to an air purification device, in particular to a marine diesel generator set exhaust purification device. Background technique [0002] Ships are a kind of carrier that can move on the water. With the development of modern shipbuilding industry, in addition to a high degree of automation, the manufactured ships have a large carrying capacity and a strong endurance. In order to meet normal navigation and daily needs, ships need to be equipped with more power equipment, auxiliary machines, instruments and living facilities, and most of these supporting equipment use electric energy. Contemporary ships in use have their own generator sets, generally diesel generator sets. Practice has proved that the diesel generator set is efficient, economical, safe and reliable, and fully meets the supporting requirements of s...
