[0002] The exhaust gas boiler condensate system of the "Xin Yong'an" ship is located in the front engine room. The water supply pump delivers water from the water storage tank to the exhaust gas boiler. The exhaust gas boiler generates steam for use by various steam systems on the ship, and the remaining steam or the return steam after use flows back to the condensate observation tank of the hot water well through the atmospheric condenser. The condensate observation tank then overflows to the water storage tank. Figure 1 The hot water well is equipped with a steam heating system controlled by an electric temperature automatic regulating valve (PID control) to ensure a constant water temperature in the hot water well.

[0003] The existing temperature sensor is installed at the water tank water pump suction port, and the three-way regulating valve (actuator) is installed at the condensate observation cabinet. However, the water temperature difference between the condensate observation cabinet and the water tank is large, resulting in poor coordination between the temperature sensor sensing temperature and the regulating valve actuator, excessive temperature adjustment, and serious impact on the life of the controller and actuator. Frequent alarms during navigation duty require duty personnel to frequently check the working conditions of various systems in the hot water well.

[0004] Therefore, the present application provides a high-stability exhaust gas boiler condensate system to solve the problems of poor temperature regulation effect and frequent alarms in the prior art condensate observation cabinets and water storage cabinets. Utility Model Content

[0007] A first pipeline is connected between the atmospheric condenser and the condensate observation cabinet, a second pipeline is connected between the water storage tank and the exhaust gas boiler, and an adjusting component is connected between the second pipeline and the first pipeline.

[0008] As an optimization, the regulating assembly includes a connecting pipe connected between the first pipe and the second pipe, and a hot water circulation pump is installed on the connecting pipe.

[0009] As an optimization, a stop valve is installed on the connecting pipe.

[0010] As an optimization, two stop valves are installed on the connecting pipe, and the two stop valves are respectively located on both sides of the hot water circulation pump.

[0011] As an optimization, a spare pipe is connected between the two stop valves, and a spare pump is installed on the spare pipe.

[0012] As an optimization, the stop valve includes a three-way valve body, the inside of the stop valve is rotatably connected to an adjusting sleeve, a valve core is fixed to the outside of the adjusting sleeve, an adjusting rod is provided inside the adjusting sleeve, the adjusting rod is rotatably connected to the valve body, the adjusting rod is fixed to the adjusting sleeve, and the valve core is connected to the internal channel of the three-way valve body.

[0013] As an optimization, a first temperature sensor and a second temperature sensor are respectively provided inside the condensate observation cabinet and inside the water storage cabinet.

[0014] As an optimization, one end of the second pipe connected to the water tank is bent downward to contact the bottom of the water tank.

[0015] This scheme is a high stability exhaust gas boiler condensate system, which has the following benefits:

[0016] The exhaust gas boiler condensate system of the present application connects a regulating component between the first pipe and the second pipe. When the temperature difference between the condensate observation cabinet and the water storage tank is greater than a preset range, the water inside the water storage tank is input into the condensate observation cabinet through the regulating component, so that the temperatures of the two are quickly balanced, reducing the alarm caused by the large temperature difference between the condensate observation cabinet and the water storage tank.
