It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of each component in actual implementation may be changed freely, and the layout of the components may be more complicated.
As shown in fig. 1, the present invention provides an exhaust system for a sanitary facility of a ship, as shown in fig. 1 to 3, the exhaust system comprising:
and the air supply module 1 is arranged in the cabin and used for supplying air to the cabin.
And the pressure monitoring unit 6 is installed in the cabin and used for monitoring the air pressure value P1 in the cabin.
Specifically, the air supply module 1 may be an air supply fan, and because a relatively constant and comfortable indoor temperature needs to be maintained in the cabin, the air supply module 1 needs to continuously supply cold air or hot air to maintain the cabin temperature, however, the air supply volume is often relatively large, so that the air pressure in the cabin is too high, and therefore, the pressure monitoring unit 6 is used to monitor the air pressure in the cabin.
The air exhaust module 2 is arranged in a sanitary place of the cabin and used for exhausting air in the cabin;
the exhaust module 2 comprises an exhaust box body 21, a check valve 22, a pipeline fan 23 and a silencing pipe section 24 which are sequentially connected, the exhaust box body 21 is connected with the check valve 22 through an inner socket joint, the check valve 22 is connected with the pipeline fan 23 through a flange, and the pipeline fan 23 is connected with the silencing pipe section 24 through a flange.
And the variable frequency fan 8 is communicated with the silencing pipe section 24 of the air exhaust module 2 through an air pipe and is used for exhausting the air extracted by the air exhaust module 2 to the external atmospheric environment. The silencing pipe section 24 is connected with an air pipe through a female spigot-and-socket joint so as to realize the communication between the exhaust module 2 and the air pipe.
The variable frequency fan 8 is provided with a fan control unit 7, the fan control unit 7 is in communication connection with the exhaust control unit 25, and the fan control unit 7 is used for controlling the operation of the variable frequency fan 8.
Further, the exhaust system further comprises an exhaust control unit 25, the exhaust control unit 25 is fixed on the casing of the pipeline fan 23 through self-tapping screws, and the exhaust control unit 25 is in communication connection with the pressure detection unit 6 to receive the air pressure value P1 in the cabin; the exhaust control unit 25 is further configured to monitor an air pressure value P2 in the air duct and control operation of the exhaust module 2 (specifically, control operation of the pipeline fan 23), when the pressure difference P1-P2> a preset pressure difference, the exhaust control unit 25 controls the pipeline fan 23 to start operation, and simultaneously sends a signal to the fan control unit 7, and the fan control unit 7 controls the variable frequency fan 8 to operate and maintain an operation power matched with the exhaust module 2. The matched operation power means that the deviation between the exhaust air volume when the variable frequency fan 8 operates and the total air pumping volume of the exhaust module 2 incorporated in the air pipe (also can be said to be the total air pumping volume of the pipeline fan 23) is kept within ± 4%.
Further, the pressure monitoring unit 6 is also used for controlling the operation of the air supply module 1; when the value of P1-P2 is still larger than the preset pressure difference after the exhaust module 2 operates for a certain time (such as 5 minutes, 10 minutes and the like), the pressure monitoring unit controls the air supply module to reduce the air supply amount. Because the air supply module 1 plays an important role in supplying cold air or hot air to the cabin to maintain the temperature of the cabin and supplying fresh air, the priority of regulation and control of the air supply module 1 is lower than that of regulation and control of the air exhaust module 2, and therefore the air supply module 1 is not regulated and controlled as far as possible to maintain the fresh air supply and the constant temperature of the cabin.
Specifically, the exhaust module 2 is installed in a bathroom of a cabin for exhausting air in the cabin (bathroom) to ventilate the cabin, the exhaust box 21 serves as an inlet of a cabin airflow, and the silencing pipe section 24 serves as an outlet of the cabin airflow. The suction box body 21 and the check valve 22 are connected by adopting an inner socket joint, and the socket joint can weaken the transmission of noise and vibration, thereby eliminating the noise generated when the check valve 22 and the pipeline fan 23 operate and the airflow noise in the corresponding air pipe. The check valve 22 is provided with a rotatable baffle, when the pipeline fan 23 operates, the pressure difference generated at two sides of the baffle enables the baffle to rotate to an open state to form an airflow channel, air in the cabin is smoothly pumped out, and when the pipeline fan 23 stops working, the baffle naturally rotates to an original closed state under the action of gravity, so that peculiar smell and damp and hot air in various sanitary places are prevented from mutually escaping and flowing backwards. The variable frequency fan is used for discharging the air pumped by each cabin exhaust module 2 to the external atmospheric environment.
As shown in fig. 1, the exhaust modules of the first, second, third, fourth and fifth compartments are all connected to the variable frequency fan 8 through air pipes, the exhaust control unit 25 receives the air pressure value P1 in the compartments and monitors the air pressure value P2 in the air pipes, when the pressure difference P1-P2> the preset pressure difference, the exhaust control unit 25 controls the pipeline fan 23 to start operation, because the air pressure value P1 in the compartments is usually slightly greater, i.e. maintains a relatively slightly positive pressure state. However, the air pressure P1 in the cabin cannot be too large, so a preset pressure difference needs to be set, when the difference between the air pressure P1 in the cabin and the air pressure P2 in the air duct exceeds the preset pressure difference standard, the air pressure in the cabin is considered to be too high, at this time, the pipeline fan 23 is turned on to draw out the air in the cabin, and the air drawn out of the cabin is further discharged to the external atmosphere through the variable frequency fan 8. Therefore, when the pipeline fan 23 operates, the variable frequency fan 8 also operates synchronously, and the operating power of the variable frequency fan 8 needs to be adjusted according to the operating condition of the pipeline fan 23, so the exhaust control unit 25 of each cabin needs to be in communication connection with the fan control unit 7 for controlling the variable frequency fan 8. The fan control unit 7 performs logical operation and analysis through the received signals sent by the exhaust control unit 25 of each cabin, and then adjusts the operating power of the variable frequency fan 8, and further adjusts the air volume of the variable frequency fan 8, so that the exhaust of the whole system meets the actual design requirements of each cabin. For example, when the pipeline fan 23 of only one cabin operates, the variable frequency fan 8 only needs to maintain a small power to meet the requirement, but when the pipeline fans 23 of a plurality of cabins operate simultaneously, the variable frequency fan 8 needs to maintain a high operating power to meet a large exhaust requirement. When the variable frequency fan 8 operates, the deviation between the exhaust air volume when the variable frequency fan 8 operates and the total air pumping volume of the pipeline fan 23 incorporated into the air pipe is kept within +/-4%, and the operating power of the variable frequency fan 8 is adjusted according to needs, so that energy conservation and intellectualization are realized.
In summary, the present invention provides an exhaust system for a marine sanitary facility, the exhaust system includes an air supply module, a pressure monitoring unit, an exhaust module, an exhaust control unit, a fan control unit and a variable frequency fan, the pressure monitoring unit is in communication connection with the exhaust control unit, the pressure monitoring unit is used for monitoring the air pressure in a cabin and feeding back the air pressure to the exhaust control unit, if the air pressure in the cabin is too high, the exhaust control unit preferentially controls the pipeline fan to start and operate so as to reduce the cabin air pressure, meanwhile, the exhaust control unit transmits a feedback signal to the fan control unit, and the fan control unit controls the variable frequency fan to start and operate and maintain a matched operating power. If the air pressure of the cabin can not be reduced to a normal level through the pipeline fan, the air supply quantity of the air supply module is reduced, and therefore the air supply module is not regulated and controlled as far as possible so as to maintain the fresh air supply and the constant temperature of the cabin. The design of the air exhaust module can reduce mechanical noise and airflow noise, and the application of the check valve enables the whole system to avoid the phenomena of mutual 'escape' and 'backflow' of peculiar smell and damp and hot air in each sanitary place. Through the cooperation of each module, finally realize the intelligent regulation of cabin interior air current, form a low noise, high comfortable, energy-saving, intelligent health institute exhaust system.
