The other end of the recovery tank is provided with a water outlet pipe. One end of the water outlet pipe penetrates into the bottom of the inner cavity of the recovery tank, and the other end of the water outlet pipe One end is sequentially connected to the required user water pipeline through the water pump, check valve and control valve; the recovery tank is provided with a remote liquid level gauge, and the water pump, control valve and remote liquid level gauge are respectively electrically connected to the controller. The controller is electrically connected with the monitoring terminal of the remote operation room.

Wherein, the recovery tank is provided with a vent pipe, the vent pipe is provided with a vent valve, the inner cavity of the vent pipe communicates with the inner cavity of the recovery tank, and the upper end of the vent pipe extends to the ground. The recovery tank is buried and arranged at a depth of 0.5-1.5 meters under the ground. There are at least two recovery funnels. The controller is a programmable controller; the remote operation room monitoring terminal is a computer.

Compared with the prior art, the utility model has the following advantages: reasonable design, simple structure and easy manufacture. It can recycle and reuse a large amount of high-quality low-pressure water that is directly discharged outside, saving water resources, not only reducing production costs for enterprises, but also reducing the pressure on environmental protection.

detailed description

Referring to Fig. 1, a low-pressure external drainage recycling device includes a recovery tank 1, a recovery funnel 2, a remote liquid level gauge 3, a water inlet pipe 4, a water outlet pipe 5, a water pump 6, a controller 7, a control valve 8, and a check valve. The valve 9 and the monitoring terminal 10 in the remote operation room, the recovery tank 1 is buried and arranged under the ground, one end of the recovery tank 1 is connected to one end of the water inlet pipe 4, and the other end of the water inlet pipe 4 extends obliquely upwards and the end is blocked, The water inlet pipe 4 is provided with a plurality of recovery funnels 2 arranged on the upper part of the ground, the inner cavity of the recovery funnel 2 communicates with the inner cavity of the recovery tank 1 through the inner cavity of the water inlet tube 4, and the other end of the recovery tank 1 is provided with There is a water outlet pipe 5, one end of the water outlet pipe 5 penetrates to the bottom of the inner cavity of the recovery tank 1, and the other end of the water outlet pipe 5 is connected to the user water pipe 11 that meets the requirements through the water pump 6, the check valve 9 and the control valve 8 in sequence; The recovery tank 1 is provided with a remote liquid level gauge 3, the water pump 6 and the remote liquid level gauge 3 are respectively electrically connected to the controller 7, and the controller 7 is electrically connected to the monitoring terminal 10 in the remote operation room. The recovery tank 1 is provided with a vent pipe 12, and the vent pipe 12 is provided with a vent valve 13. The inner chamber of the vent pipe 12 communicates with the recovery tank 1, and the upper end of the vent pipe 12 extends to the ground. The recovery tank 1 is buried and arranged at a depth of 0.5-1.5 meters under the ground. The recovery funnel 2 is set at least 2 (2 in the figure). The controller 7 is a programmable controller; the remote operation room monitoring terminal 10 is a computer.

Recover the location of the low-pressure external drainage according to the needs, and determine the installation location of the low-pressure recovery tank 1. The low-pressure external drainage flows into the recovery funnel 2 by its own gravity, and then flows to the low-pressure water recovery tank 1, the recovery tank 1 and the water inlet pipe 4 along the sloped water inlet pipe 4 The use of underground burial avoids freezing of pipelines in winter. After the low-pressure water is recovered to the recovery tank 1, the remote liquid level gauge 3 displays the liquid level on the DCS screen of the monitoring terminal 10 in the remote operating room through the controller 7. When the liquid level reaches the set value, the water pump 6 is started, and the recovered water passes through the The check valve 9 at the outlet of the water pump 6 prevents the reclaimed water from flowing backwards. Through the outlet control valve 8 and the outlet pipeline, the liquid level is used to control the frequency conversion of the reclaimed water pump, so that the reclaimed water can be continuously transported to the water pipeline 11 of the user meeting the requirements, such as hydrofining reaction Water injection, cooling water of high temperature pump machine seal, circulating water, coking cold coke water, etc. are reused.

The utility model has the advantages of reasonable design, simple structure and easy manufacture. It can recycle and reuse a large amount of high-quality low-pressure water that is directly discharged outside, saving water resources, not only reducing production costs for enterprises, but also reducing the pressure on environmental protection.
