Description

Energy-saving vacuum drainage pipeline air supplementing and cleaning device

Technical Field

The utility model relates to the technical field of sewage treatment equipment, in particular to an energy-saving type vacuum drainage pipeline air supplementing and cleaning device.

Background

The length of the vacuum sewage collecting pipeline of the vacuum negative pressure sewer system is very elastic, and can be sucked from 500-6,000 meters of pipe length under vacuum negative pressure, but the problem faced by practical use is that the following problems are often encountered when the vacuum pipeline section is collected through such a long area: (1) Conditions of ascending a river channel, crossing a bridge or descending when encountering obstacles, upwarp and walking and the like are required, and the special conditions often consume a great amount of vacuum lifting capacity so as to influence the speed and distance of water body transportation of the pipeline, thereby causing water congestion in the pipeline; (2) The long-distance vacuum pipeline is easy to generate excessive water quantity and insufficient vacuum air quantity in the pipeline, so that the steam-water mixing flow speed in the pipeline is reduced, the vacuum pipeline is further full of sewage water to generate water plug, sundries in the sewage can be accumulated inside and outside the pipeline, the vacuum pipeline can not simultaneously finish conveying sewage and distributing vacuum station vacuum negative pressure atmosphere to a vacuum well to which a system belongs, and the vacuum well has enough vacuum negative pressure to start pumping sewage in the well.

To solve the above problems, the technical staff researches a vacuum self-cleaning air-supplementing device and installs a plurality of branch pipes in the system, but due to the excessive installation quantity, the load of the vacuum pump of the vacuum station for pumping vacuum is easy to be caused, namely, a large amount of atmospheric air is introduced by the vacuum self-cleaning air-supplementing device and then a large amount of vacuum air source is lost, when the vacuum system is restarted (at the moment, the vacuum negative pressure value in the vacuum pipe is zero), so the vacuum station of the system is subjected to the following two stages from 0kpA to the system stop pumping point (-60 kpA to-65 kpA) when the vacuum system is restarted

A. Stage 0 to a predetermined threshold (typically-30 to-50 kpA) for air make-up;

B. the phase is that the air supply is preset to the system vacuum to meet the threshold;

the vacuum air quantity used in the stage A is the largest, and the vacuum air quantity loss of the air supplementing air of all the vacuum self-cleaning air supplementing devices is needed to be overcome besides the actual requirement of the vacuum pipeline, because the vacuum self-cleaning air supplementing devices can automatically start to introduce the air because the vacuum pipeline belongs to the abnormal low-pressure condition, and the system vacuumizing load is caused; and in the B stage, because the pipeline cleaning meets the set point pressure, the air supplementing cleaning action can not be performed any more, and all the vacuum air quantity can directly meet the vacuum degree of the vacuum pipeline to quickly raise. In contrast, if the system is started and completed, the vacuum pipeline is switched from high pressure to low pressure to run, and the problems of energy consumption and large amount of air extraction running are avoided.

The related air supplementing and cleaning principle is as follows:

the sewage in the vacuum sewage collecting system can rapidly advance in the vacuum pipeline, the sewage is conveyed to the vacuum station by the source vacuum well, besides the vacuum gas pumping sewage moves in the pipeline, a large amount of air is pumped out at the same time when the vacuum well is opened and closed or before the vacuum valve is closed each time, the air enters the vacuum pipeline and then is flushed to a high-vacuum area (generally, a vacuum negative pressure barrel in the vacuum station is the highest-vacuum source) at a very high speed, and the high-speed gas can strongly push the sewage blocked in front of the vacuum pipeline to advance and form a gas-water mixed rapid conveying type.

In theory, the gas-liquid ratio of the sewage transported in the normal area is about 7:1-14:1, and the larger the ratio is, the stronger the vacuum transporting capability is, but the more vacuum power is consumed to exhaust the pipeline atmosphere entering the system at the same time, depending on the size and distance of the collecting area and the obstacle avoidance condition.

The energy-saving technology principle is as follows:

the vacuum pipeline pressure detection and the air supplementing operation in the air supplementing cleaning device are separately arranged, the pipeline vacuum negative pressure setting point (adjustable-30-50 kpA) is carried out on the vacuum pressure detection facility, the air supplementing starting threshold is additionally arranged on the air supplementing device, and the part of the excessively low pipeline section vacuum negative pressure value (minus 20 to minus 25 KPA) is regarded as that the air supplementing valve in the abnormal operation cleaning device cannot be opened and does not act as air supplementing.

Based on the above theory, the embodiment of the application provides an energy-saving vacuum drainage pipeline air supplementing cleaning device, see fig. 1 and 3, including vacuum valve a and negative pressure controller B, the negative pressure controller includes vacuum output port 9 and first vacuum pipeline interface 10, the vacuum valve includes vacuum input port A9 and second vacuum pipeline interface a10, first vacuum pipeline interface access vacuum pipeline, second vacuum pipeline interface access vacuum pipeline, the vacuum output port of negative pressure controller with the vacuum input port intercommunication of vacuum valve, the opening and the closing of vacuum valve can be controlled to the big or small change of the vacuum negative pressure value of negative pressure controller output.

In this embodiment, the negative pressure controller is configured to monitor a vacuum negative pressure value in the vacuum pipe, and when the vacuum negative pressure value is smaller than a preset starting threshold of the negative pressure controller, the negative pressure controller is automatically communicated to transmit vacuum negative pressure gas in the vacuum pipe to the vacuum valve; when the vacuum negative pressure value in the vacuum pipeline is larger than the starting preset threshold value of the negative pressure controller, the negative pressure controller can shut off the vacuum gas transmitted to the vacuum pipeline of the vacuum valve and does not react.

The vacuum valve receives the vacuum negative pressure value transmitted from the negative pressure controller, when the vacuum negative pressure value is larger than a starting preset threshold value of the vacuum valve, the vacuum valve acts and is conducted to supplement the atmosphere into the vacuum pipeline for cleaning, and when the vacuum negative pressure value is smaller than the starting preset threshold value of the vacuum valve, the vacuum valve does not act and does not perform air supplementing cleaning.

That is, the activation of the air-supplementing cleaning device in the present application needs to satisfy two predetermined thresholds, that is, between the predetermined threshold for activating the vacuum valve and the predetermined threshold for activating the negative pressure controller, the air-supplementing cleaning device is activated to perform the air-supplementing cleaning operation.

Referring to fig. 4 and 7, the negative pressure controller comprises a first chamber 1, a second chamber 2, a third chamber 3, a fourth chamber 4 and a first switching mechanism 5 for connecting the first chamber, the second chamber, the third chamber and the fourth chamber, wherein the first chamber and the third chamber are communicated, the second chamber is communicated with the atmosphere, the third chamber is provided with the first vacuum pipeline interface, the third chamber is communicated with a vacuum pipeline, the fourth chamber is provided with the vacuum output port, and the vacuum output port is communicated with the vacuum valve; a first air supplementing channel is arranged between the third chamber and the fourth chamber, and the air pressure change in the first chamber can drive the first switching mechanism to act so as to enable the first air supplementing channel to be conducted or closed; when the vacuum pipeline is in a normal state, the vacuum pressure value is large enough to enable the first diaphragm to deform and compress the first spring, the blocking block at the tail end of the first moving shaft blocks the first air supplementing channels of the third cavity and the fourth cavity, namely, the first moving shaft is located at the closed position, when the vacuum pipeline encounters a water plug or a water lifting elevation, the vacuum pressure is insufficient, the pressure difference between the first cavity and the second cavity is smaller than the resilience force of the first spring, the resilience force enables the first spring to extend and drive the first diaphragm to drive the first moving shaft to move towards the conducting position of the third cavity and the fourth cavity, namely, the blocking block at the tail end of the first moving shaft leaves the first air supplementing channels of the third cavity and the fourth cavity, at the moment, a large amount of vacuum atmosphere in the third cavity enters the fourth cavity and flows to the connected vacuum valve through the fourth cavity, when the vacuum negative pressure value entering the vacuum valve is larger than the starting preset threshold value of the vacuum valve, the second switching mechanism in the vacuum valve acts, the second air supplementing channel in the vacuum valve is conducted, and the air supplementing cleaning device begins to act, and the cleaning device does not act.

Referring to fig. 4-7, the first switching mechanism 5 includes a first diaphragm 51 and a first moving shaft 52, where the first diaphragm is used to connect the first chamber and the second chamber and make the first chamber and the second chamber not communicate with each other, a head end of the first moving shaft is located in the second chamber and connected to the first diaphragm, a tail end of the first moving shaft passes through the third chamber and is located in the fourth chamber, and a pressure in the first chamber changes to drive the first diaphragm to deform so as to drive the first moving shaft to synchronously move, and a tail end of the first moving shaft moves back and forth between a conducting position and a closing position of the third chamber and the fourth chamber.

Further, the first switching mechanism further comprises a first spring 53, which is disposed in the first chamber and connected to the first diaphragm; the first diaphragm deformation can compress a first spring so as to enable the first moving shaft to move towards the closing positions of the third chamber and the fourth chamber, and the resilience force of the first spring can drive the first diaphragm to drive the first moving shaft to move towards the conducting position of the first air supplementing channel; specifically, when the negative pressure difference between the vacuum pressure and the atmosphere is greater than or equal to a preset threshold value of the negative pressure controller, the first diaphragm extrudes the first spring to compress, and the first moving shaft is positioned at the closing position of the third chamber and the fourth chamber, and at the moment, the negative pressure controller does not act; when the difference between the vacuum pressure and the negative pressure of the atmosphere is smaller than a preset threshold value, the resilience force of the first spring enables the first spring to stretch and drive the first moving shaft to be located at the conducting position of the third chamber and the fourth chamber, and at the moment, the negative pressure controller starts the action of conveying vacuum gas to the vacuum valve.

Specifically, the first chamber is provided with a negative pressure meter 7 reflecting the vacuum negative pressure value in the first chamber (the vacuum negative pressure value in the third chamber is measured by the negative pressure meter because the first chamber is connected with the third chamber), the vacuum negative pressure value in the vacuum pipeline can be displayed in real time according to the negative pressure meter because the vacuum in the first chamber comes from the vacuum pipeline, and when the absolute value of the vacuum negative pressure in the vacuum pipeline is larger than the preset threshold value of the negative pressure controller, the vacuum negative pressure in the vacuum pipeline is normal, so that the negative pressure controller does not perform any reaction and action; conversely, when the absolute value of the vacuum negative pressure in the vacuum pipeline is smaller than the preset threshold value of the negative pressure controller, the negative pressure controller automatically opens the vacuum valve for introducing vacuum gas.

In some embodiments, in order to adapt to the vacuum negative pressure value of more vacuum pipelines and accurately control the opening and closing of the negative pressure controller, the first chamber is provided with an adjusting bolt 8 for adjusting the compression amount of the first spring, one end of the adjusting bolt is connected to a top block in the first chamber, the other end of the adjusting bolt is positioned outside the negative pressure controller, and the adjusting bolt is rotated from outside to squeeze the top block in the first chamber, so that the compression amount of the first spring is increased; when the adjusting bolt is screwed down, the first spring is compressed downwards, so that the first spring is accumulated with larger resilience force, at the moment, the first spring is limited to be in a constant state by the fact that larger vacuum negative pressure value is needed to attract compression, the first spring does not stretch to push the first moving shaft below, and a preset threshold value of higher vacuum negative pressure absolute value can be obtained, and the first spring can be actuated to recover as long as the preset threshold value is smaller than the preset threshold value; conversely, when the adjusting bolt is screwed upwards, the compression and limitation on the first spring are reduced, and a smaller vacuum negative pressure value can be obtained at the moment to enable the first spring to be loosened and stretched, so that the adjusting bolt is used for adjusting the negative pressure controller according to the field requirement to enable the negative pressure controller to meet the requirements of starting and closing of the current environment; it is understood that the predetermined threshold may be adjusted by adjusting the bolt and thus the first spring compression, and different vacuum negative pressure environments correspond to different predetermined thresholds.

Specifically, the end of the first moving shaft is provided with a substantially conical blocking block 521, the blocking block 521 is used for conducting or closing the first moving shaft at the first air supplementing channel of the third chamber and the fourth chamber, when the first moving shaft moves downwards, the blocking block 521 is pushed into the fourth chamber, at this time, the first air supplementing channel is opened, and a large amount of air enters the fourth chamber and flows to the connected vacuum valve through the first air supplementing channel.

In this embodiment, the negative pressure controller is configured to monitor a vacuum negative pressure value in the vacuum pipe, and when the vacuum negative pressure value is smaller than a preset starting threshold of the negative pressure controller, the negative pressure controller is automatically communicated to transmit vacuum negative pressure gas in the vacuum pipe to the vacuum valve; when the vacuum negative pressure value in the vacuum pipeline is larger than the starting preset threshold value of the negative pressure controller, the negative pressure controller can shut off the vacuum gas transmitted to the vacuum pipeline of the vacuum valve and does not react.

when the vacuum negative pressure value in the first air chamber of the vacuum valve is smaller than the starting preset threshold value of the vacuum valve, the vacuum negative pressure value with the low height (smaller than the starting preset threshold value) cannot drive the second switching mechanism to act, the vacuum valve does not act, the tail end of the second moving shaft is blocked at the second air supplementing channel, the third air chamber and the fourth air chamber are not conducted, and the device does not conduct air supplementing cleaning work.

When the vacuum negative pressure value in the first air chamber of the vacuum valve is larger than the starting preset threshold value of the vacuum valve, the second diaphragm of the vacuum valve deforms and compresses the second spring under the vacuum negative pressure value of the higher vacuum degree (larger than the starting preset threshold value), the second moving shaft moves towards the first air chamber, the tail end of the second moving shaft leaves the second air supplementing channel of the third air chamber and the fourth air chamber, the third air chamber is communicated with the fourth air chamber, and the atmosphere of the third air chamber flows into the vacuum pipeline through the fourth air chamber to start air supplementing cleaning.

When the vacuum pipeline gradually recovers the normal vacuum negative pressure value due to the gas sweeping function, the higher vacuum negative pressure value is larger than the preset threshold value of the negative pressure controller, the negative pressure controller can automatically cut off the transmission of vacuum negative pressure gas to the vacuum valve, the vacuum valve suddenly loses vacuum negative pressure attractive force, a second diaphragm in the first air chamber is not sunken towards the first air chamber and is restored to be smooth, at the moment, the second spring is reduced due to the thrust of the second diaphragm, the rebound force of the spring is generated again to stretch to drive the connected second moving shaft to be closely adhered to a sealing ring at the second air supplementing channel, the third air chamber and the fourth air chamber are not conducted, the atmosphere gas from the third air chamber is cut off, the air supplementing operation is stopped, namely the air supplementing sweeping device stops the air supplementing operation, and the pipeline sweeping operation is ended.
