Embodiment Construction

[0020] The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. This embodiment is an example of application of the present invention to a waste water discharge device for recovering waste water generated in a plurality of air conditioners installed in office buildings and the like to one place and discharging it to the outside.

[0021] FIG. 1 is a block diagram of a drain water discharge device 100 according to an embodiment of the present invention. The device includes a suction recovery main body A and a plurality of terminal units B, and the terminal units B are connected to the suction recovery main body A through a discharge water recovery main pipe 3 .

[0022] The above-mentioned suction recovery main unit A is installed in an underground equipment room and a tube well of a building such as an office building, etc., at a position lower than the air conditioner 20 (terminal unit B) which is a source of li...

Abstract

A liquid discharging device and a liquid discharging method, wherein liquid discharge control valves (13, 14) of a second tank (2) are brought into a closed state, a main valve (4) between a first tank (1) and the second tank (2) is brought into an open state, and a pressure in the second tank (2) is reduced by a pressure reducing means (8) to suckingly recover a liquid in a liquid storage tank (21) to the second tank (2) through a liquid suction pipe (22) and the first tank (1). When the liquid discharge control valves (13, 14) are opened after the main valve (4) is closed, the liquid is discharged from the second tank (2) while the first tank (1) is held in a depressurized state. Then, the liquid discharge control valves (13, 14) are closed, and after the second tank (2) is depressurized by the pressure reducing means (8), the main valve (4) is opened.

Description

technical field [0001] The present invention relates to a liquid discharge device and a liquid discharge method, for example, suitable for continuously recovering and discharging drain water (dren) generated by the operation of air conditioners for building air conditioners and the like. Background technique [0002] As a effluent discharge device that continuously recovers and discharges effluent generated by the operation of an air conditioner used in building air conditioners, etc., there has been proposed a effluent discharge device that normally maintains a predetermined degree of vacuum and sucks and recovers water from the air conditioner. A first container for the drain water discharged from the first container; a second container for supplying the drain water from the first container; a main valve for controlling the supply of the drain water from the first container to the second container; when the main valve is closed, The drain control valve is opened to dischar...
