Problems solved by technology

Therefore, the above-mentioned steam inlet of the communication pipe is formed small, and it is difficult to efficiently take in the water vapor evaporated in the evaporation region into the steam inlet.
Therefore, it is difficult to ensure the amount of condensation of water vapor evaporated by the waste heat of the engine, and it is difficult to ensure a sufficient amount of distilled water.

Abstract

An engine-driven operation machine is provided. The engine-driven operation machine (10) is provided with a water generation device (20). The water generation device (20) allows raw water (29) to evaporate by utilization of waste heat of an engine (12), and allows water vapor evaporated to condense to generate purified water (69). The water generation device (20) is provided with an evaporator (35). The evaporator (35) allows the raw water (29) to evaporate by utilization of waste heat of waste gas guided by a heating part (53). The evaporator (35) is provided with: a gas taking part (66) for taking waste gas from a gas discharging pipe (27); and a gas discharging part (67) for discharging the waste gas into the gas taking part (66) to the outside (68) of the evaporator (35). A heating main body (65) is inclined to form a downward slope from towards the gas taking part (66) to the gas discharging part (67).

Description

technical field [0001] The present invention relates to an engine-driven working machine provided with a water generating device for evaporating raw water by using waste heat of an engine, and condensing the evaporated water vapor to generate purified water. Background technique [0002] For example, as disclosed in Japanese Patent Application Laid-Open No. 2012-24699, there is known an engine-driven working machine that takes water (raw water) from a river or the like into a water pump, diverts a part of the taken-in raw water, and utilizes The residual heat of the engine evaporates the diverted raw water, and uses the diverted raw water to condense the evaporated steam to generate clean water. [0003] According to this engine-driven work machine, when the water pump is driven, a part of the raw water taken into the water pump is guided to the raw water distribution pipe, and the guided raw water is introduced into the exhaust pipe of the engine through the raw water distr...
