Detailed Description
The invention is further illustrated, but not limited, by the following specific examples.
EXAMPLE 1 residual Water Recycling device
The invention relates to a residual water recycling device, which consists of a raw water tank (2), a purified water machine (4) and a purified water tank (6), wherein the top of the raw water tank is provided with a municipal water inlet (1) and a reuse water inlet (12), the side of the raw water tank is provided with a raw water tank liquid level meter (3), the bottom of the raw water tank is connected with a water production pump (13) through a pipeline, water is conveyed into the purified water machine (4) through the water production pump, water in the purified water machine (4) enters the purified water tank (6) through a purified water inlet (5), the side of the purified water tank is provided with a purified water liquid level meter (7), the bottom of the purified water tank is connected with a water outlet pump (15) through a pipeline (14) and is conveyed to a purified water point by the pump, the lower part of the pipeline is connected with a connecting pipe (16), the pipeline is provided with an emptying valve (8), the lower part of the pipeline is divided into two branch pipelines, a drain valve (9) is arranged on a discharge pipe (17), the recycling pipe (18) is connected with a recycling water inlet (12) of the raw water tank (2), and a water return pump (11) and a recycling valve (10) are also arranged on the branch flow pipeline.
Examples 2,
Normal purified water preparation process:
municipal administration water gets into former water pitcher (2) from municipal administration water import (1) to liquid level according to former water pitcher level gauge (3) judges, and the water intaking is to certain liquid level, and later water goes out from the tank bottoms, carries into purified water machine (4) by producing water pump (13), carries out multichannel purification processing, gets into purified water pitcher (6) storage through purified water import (5) at last, and judges by purified water level gauge (7) that purified water product goes out to how many liquid levels. When the purified water tank (6) meets the requirements, the purified water is conveyed to a purified water using point by a pump.
Reason for purified water discharge:
1. during normal operation, the purified water of more than 50% liquid level can be stored in the purified water tank (6), when the purified water system needs to be shut down due to reasons such as production stoppage, the purified water tank (6) needs to be emptied, and the purified water tank can enter a sewer of a plant area through the emptying valve (8) and the drain valve (9).
2. When the water quality index reaches the warning limit, the purified water is discharged to the water production liquid level through the emptying valve (8) and the drain valve (9), so that the purified water machine starts to produce new water for recovering the water quality index.
The water yield that above 2 kinds of circumstances discharged is more, and quality of water is higher than municipal water, in order not to waste the water resource, we improve current device, and the high efficiency utilizes the recovery water of emission.
Example 3, recovered water operating principle:
1. liquid level parameter adjustment:
the raw water replenishing liquid level of the raw water tank liquid level meter (3) is limited by 20-50 percent, municipal water is replenished when the raw water replenishing liquid level is lower than 20 percent, and the municipal water is stopped when the raw water replenishing liquid level is higher than 50 percent, so that the resident liquid level of the raw water tank (2) is lower than half of the original liquid level, and the recovered water is convenient to store.
Purified water is fed into the purified water tank by the purified water level meter (7) and is limited by the purified water feeding liquid level (50% -80%), purified water starts to be produced when the purified water level is lower than 50%, and purified water stops being produced when the purified water level is higher than 80%, so that the purified water tank (6) stays at the liquid level which is not more than 80%, and the situation that the recovered water is too much and the raw water tank (2) cannot be recovered and stored is avoided.
2. When the machine is stopped for draining, the purified water recovery mode is as follows:
the purified water machine (4) stops running, the emptying valve (8) and the water return valve (10) are opened, the water return pump (11) is started, and discharged purified water is conveyed to enter the raw water tank (2) through the recycled water inlet (12).
During purified water conveying, liquid levels of a raw water tank liquid level meter (3) and a purified water liquid level meter (7) are judged and started, and the following 3 conditions are provided:
A. the numerical value of the raw water tank liquid level meter (3) is less than 100 percent, and the numerical value of the purified water liquid level meter (7) is more than or equal to 2 percent, and the purified water is normally conveyed.
B. The numerical value of the raw water tank liquid level meter (3) is more than or equal to 100%, the numerical value of the purified water liquid level meter (7) is more than or equal to 2%, the water return pump (11) stops, (10. the water return valve) is closed, (9. the drain valve) is opened, and the purified water tank is emptied (6).
C. The numerical value of the raw water tank liquid level meter (3) is less than 100 percent, the numerical value of the purified water liquid level meter (7) is less than or equal to 2 percent, and for protecting the water return pump (11), the water return pump (11) stops, the water return valve (10) is closed, the drain valve (9) is opened, and the purified water tank (6) is emptied. 3, when the water quality does not reach the standard, the purified water is recovered:
in the normal operation process, when the water quality index of the purified water reaches the warning value, the liquid level of the purified water tank (6) is more than 50%, the emptying valve (8) and the water return valve (10) are opened, the water return pump (11) is started to convey the discharged purified water, and the purified water enters the raw water tank (2) through the recycled water inlet (12).
When the value of the purified water liquid level meter (7) is less than or equal to 30%, the water return pump (11) stops, the water return valve (10) and the emptying valve (8) are closed, the purified water machine starts to produce water, and the liquid level of the purified water tank (6) is restored to be more than 80%.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
