摘要： A gas concentration measuring device including a light emitter and a light receiver which are disposed so as to be opposed to each other with a hollow tube-like measurement pipe interposed therebetween. The device is configured to measure concentration of target gas passing through the measurement pipe using light applied from the light emitter, transmitted through the inside of the measurement pipe, and received by the light receiver. Purge gas guide pipes through which purge gas is introduced into optical systems of the light emitter and the light receiver are connected to a side wall of the measurement pipe. The measurement pipe includes a gas entrance portion having a tapered shape widening from a gas supply port toward a downstream side thereof.

摘要： The purpose of the present invention is to provide a urea solution injection nozzle in which deposition and growth of urea on the surface of the urea solution injection nozzle are minimized. A urea solution injection nozzle is provided with urea solution flow paths and gas flow paths. A mixture of urea solution and gas are injected from an injection port. A slit that is a side-surface discharge port is configured so that gas is discharged along a curved surface on the outer surface of the urea solution injection nozzle in the same direction as the injection direction of the urea solution. The slit and the flow path are connected by a branching flow path.

摘要： The purpose of the present invention is to provide an exhaust purification device that is capable of adding an appropriate amount of urea solution without the need to directly measure the NOx emissions amount using an NOx measuring means. The exhaust purification device uses urea solution as a reducing agent for reducing nitrogen oxides within exhaust, and is provided with a temperature sensor, a humidity sensor, and a control device. A map is stored in the control device, and in said map the real NOx emissions amount for each rotation speed and each load of an engine occurring at a predetermined air temperature and a predetermined absolute humidity are converted using a correction formula into a reference NOx emissions amount for each rotation speed and each load of the engine while in a standard state. Using the map, the control device calculates a reference NOx emissions amount that corresponds to the rotation speed detected by a rotation speed sensor and to the load detected by a load sensor, uses the correction formula to convert the reference NOx emissions amount into the real NOx emissions amount occurring at an air temperature and an absolute humidity, and calculates a urea solution addition amount.

摘要： An exhaust gas purification system includes, as an exhaust gas path of an engine to be mounted in a ship, a main path which is in communication with outside, a bypass path which branches off from a halfway portion of the main path, and a combined casing with which both the main path and the bypass path are in communication. A selective catalyst reduction device is accommodated in the combined casing at a location close to the main path. A path-switching member which switches exhaust gas moving direction is placed in a branched portion between the main path and the bypass path. A reducing agent injection body is placed in the main path between the path-switching member and the combined casing.

摘要： In an exhaust gas purification apparatus provided in an exhaust as path of an engine, it is an object of the present invention to shorten a pipe length of a bypass path bypassing a purification catalyst as short as possible, thereby reducing initial costs. The exhaust gas purification apparatus includes a purification casing in which at least the purification catalyst is accommodated. The purification catalyst purifies exhaust gas from the engine. The purification casing is integrally provided with the bypass path separately from the purification path in which the purification catalyst exists. The bypass path makes the exhaust gas bypasses the purification catalyst without passing through the purification catalyst.

摘要： An exhaust gas purifier including a casing, SCR catalysts (comprising a first SCR catalyst and a second SCR catalyst), a first backflow prevention plate, and a second backflow prevention plate. In the casing, at least a part of the catalyst passage and at least a part of the bypass passage are formed. The SCR catalysts are disposed in the catalyst passage and selectively reduce NOx included in an exhaust gas flowing in the catalyst passage. The first backflow prevention plate prevents or reduces a backflow of an exhaust gas from a second exhaust passage to the catalyst passage.
