A tail gas treatment device and tail gas treatment system

Abstract

The invention provides a tail gas treatment device and a tail gas treatment system, and relates to the technical field of tail gas treatment, the tail gas treatment device comprises a tail gas collection box connected with the top of a chimney exhaust pipe, a component sensor at a preset position in the tail gas collection box, a spray pipe (provided with a plurality of nozzles) and a collection box exhaust pipe; the spraying pipe is connected with the spraying liquid storage cabin; a first electromagnetic valve is arranged between the tail gas collecting box and the spraying liquid storage cabin; the tail gas collecting box collects tail gas exhausted by the chimney exhaust pipe; the component sensor sends a prompt signal when detecting that the particulate matter content of the tail gasexceeds a preset threshold value; when the first electromagnetic valve is opened, the spraying pipe is conducted; the spray liquid storage cabin sprays the tail gas in the tail gas collection box through the spray head when the spray pipe is conducted, and discharges the sprayed gas through the collection box exhaust pipe. Tail gas particulate matter pollution can be effectively treated with low cost, the weight center of gravity of a ship is hardly affected, and the space utilization rate of the ship can be increased.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment, in particular to a tail gas treatment device and a tail gas treatment system. Background technique [0002] At present, ships mainly use diesel engines as power devices. In addition to carbon dioxide, which causes the global warming effect, the gas pollutants produced include a large amount of exhaust pollutants such as SOx, NOx, and particulate matter (PM), which bring great harm to human living environment and health. Very dangerous. At present, the methods for ship exhaust pollutants can be roughly divided into pre-treatment, intermediate treatment and post-treatment technologies. The pre-treatment technology usually uses low-sulfur fuel oil to reduce PM emissions, and the intermediate treatment technology mainly optimizes the fuel injection system and combustion methods. And improvement, including electronic control technology and intake supercharging and intercooling technology, ...

AI Technical Summary

Problems solved by technology

[0003] However, the cost of low-sulfur fuel oil used in the pre-treatment technology is relatively high, and the internal structure of the engine body needs to be improved in the intermediate treatment technology, which will greatly increase the purchase cost of the diesel engine. The space for its layout and maintenance reduces the utilization rate of the space on the ship, and it is mainly arranged inside the chimney on the ship, and the position of the arrangement is relatively high, which is unfavorable for the control of the weight and center of gravity of the ship

Therefore, the existing exhaust gas treatment technology has the problems of high cost and complicated space layout.
