Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The invention provides a high-altitude area positive pressure chamber sewage discharge system.

Referring to fig. 1 and 2, in the preferred embodiment, a high-altitude area positive pressure chamber sewage discharge system comprises a terminal water collector 1 for storing non-irritant odor-free waste water (mainly shower water), a water seal device 4 for preventing odor in a pipe network from escaping, a drainage diaphragm valve 2 for cutting off the pressure of indoor and outdoor air to ensure that the indoor pressure does not leak, a drainage pipe network 3 for discharging indoor sewage to a positive pressure environment (a waste water storage tank can be arranged in the drainage pipe network 3 to store sewage), and an inflation system for inflating the drainage diaphragm valve 2, wherein, water seal arrangement 4 is located the delivery port department of terminal water collector 1, and drain pipe network 3 is connected with the play water end of water seal arrangement 4, and drainage diaphragm valve 2 is installed on the drain pipe network 3 of water seal arrangement 4 delivery port department, and gas charging system communicates with the air inlet of drainage diaphragm valve 2.

Further, a liquid level meter 7 is installed inside the terminal water collector 1 to measure liquid level information of the terminal water collector 1.

Further, this high altitude area positive pressure room sewage discharge system still includes vacuum pump station 6, and the inflation system includes the tee bend pipeline, and the first port and the air inlet intercommunication of drainage diaphragm valve 2 of tee bend pipeline, the second port of tee bend pipeline communicate with outside atmosphere through exhaust solenoid valve, and the third port of tee bend pipeline communicates through the gas vent of 8 and the vacuum pump station 6 of admitting air solenoid valve, and the extraction opening and the drainage pipe network 3 intercommunication of vacuum pump station 6.

The vacuum pump station 6 is used for generating the vacuum of pipeline, and one end connects to the drainage pipe network 3, and the other end connects to the inflation system, utilizes the negative pressure of drainage pipe network 3 to give the transmission malleation of inflation system, guarantees that drainage diaphragm valve 2 valve clack is closed under normal conditions. Compared with an inflation system formed by independently arranging a blower, the positive pressure chamber sewage discharge system is simpler in structure and less in equipment.

The drainage diaphragm valve 2 is inflated through the vacuum pump station 6, when the vacuum pump station 6 vacuumizes the drainage pipe network 3, the other end of the vacuum pump station 6 generates pressure higher than outdoor atmospheric pressure, one end of the inflation system is connected to the outlet end of the vacuum pump station 6, and the other end of the inflation system is connected to the drainage diaphragm valve 2, so that pressure for closing the valve clack is provided for the drainage diaphragm valve 2.

Further, the high-altitude area positive pressure chamber sewage discharge system further comprises a controller 5 electrically connected with the liquid level measuring meter 7, the exhaust electromagnetic valve, the air inlet electromagnetic valve 8 and the vacuum pump station 6. According to the data measured by the liquid level meter 7, the automatic control of the opening and closing of the drainage diaphragm valve 2 is realized through the controller 5.

In particular, the inflation system is a corrosion resistant plastic or metal tube. The tail end water collector 1 is made of stainless steel materials and internally provided with a flow guide system, a water inlet is positioned at the top, a water outlet is positioned at the bottom, and the effective volume of the tail end water collector 1 is 90L-120L so as to meet the storage requirements of washing waste water for more than six times and the storage requirements of shower waste water for 1/3 times.

Referring to fig. 3, the water seal device 4 adopts a U-shaped trap, the height of the inlet of the U-shaped trap is greater than that of the outlet, and the height difference (L3 in fig. 3) of the pipes at both sides of the U-shaped trap is 1/6 to 1/4 of the distance (L1 in the figure) from the outlet of the U-shaped trap to the drainage diaphragm valve 2.

In the process of filling the water seal device 4, air with the length of L1+ L2 exists at the right side of the U-shaped trap because the drain diaphragm valve 2 is closed, and the water seal can only be realized by overcoming the air pressure of the section. Therefore, the height of the U-shaped trap inlet side pipeline is higher than that of the outlet side pipeline, and the height difference is reasonably set, so that the water sealing effect is ensured.

Further, referring to fig. 2, the drainage pipe network 3 is also communicated with a domestic wastewater drainage pipe (domestic wastewater includes toilet wastewater), and a drainage diaphragm valve 2 is installed at the water outlet of the domestic wastewater drainage pipe (the drainage diaphragm valve 2 is also communicated with the vacuum pump station 6 through an air inlet solenoid valve 8).

In fig. 2, the upper pipeline is a schematic diagram of the communication between the drainage pipe network 3 and the domestic wastewater drainage pipe, and the lower pipeline is a schematic diagram of the communication between the drainage pipe network 3 and the terminal water collector 1.

The working principle of the high-altitude area positive pressure chamber sewage discharge system is as follows.

When drainage is needed, the liquid level signal of the tail end water collector 1 or the signal input of the forced drainage signal controls the exhaust electromagnetic valve of the inflation system to be opened under the action of the controller 5, at the moment, the inflation system is communicated with the outdoor, the indoor pressure P1 is always greater than the outdoor pressure P2, the drainage diaphragm valve 2 is opened under the action of indoor positive pressure, and indoor sewage is discharged into the vacuum pump station 6 through a pipe network under the action of indoor positive pressure.

After a period of time of drainage, the liquid level drops or according to a control command of closing drainage, the air inlet solenoid valve 8 of the inflation system is opened, because the pressure P3 of the exhaust port of the vacuum pump station 6 is greater than the indoor pressure P1 and also greater than the outdoor pressure P2, the drainage diaphragm valve 2 is closed under the pressure action of the air inlet system at the moment, then the water seal device 4 is filled with water, the water seal is ensured to be complete, meanwhile, the pressure of the positive pressure chamber is ensured not to leak, and therefore, the system completes a drainage process under the action of indoor positive pressure.

The high-altitude area positive pressure chamber sewage discharge system that this embodiment provided has guaranteed the smooth emission of sewage under the malleation environment through setting up drainage diaphragm valve 2, makes sewage system's harmful gas can not anti-escape to the room simultaneously, has guaranteed the air quality. In addition, the high-altitude area positive pressure chamber sewage discharge system has the advantages of simple structure, easy realization and reliable work.

The invention further provides a control method of the high-altitude area positive pressure chamber sewage discharge system.

In the preferred embodiment, a control method for a high-altitude area positive pressure chamber sewage discharge system comprises the following steps:

when the liquid level of the tail end water collector 1 is greater than a preset liquid level (the preset liquid level is a preset value, drainage is started when the liquid level is greater than the preset liquid level, and drainage is stopped when the liquid level is less than or equal to the preset liquid level) or a forced drainage signal is received, the exhaust solenoid valve is opened, the drainage diaphragm valve 2 is opened, and indoor sewage is drained into the drainage pipe network 3 under the action of indoor forward pressure;

when the liquid level of the tail end water collector 1 is less than or equal to the preset liquid level or a water closing and draining signal is received, the air inlet electromagnetic valve 8 is opened, the water draining diaphragm valve 2 is closed, indoor sewage is drained into the water draining pipe network 3 under the action of indoor forward pressure, and water of the tail end water collector 1 stops being drained.
