[0017] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure.
[0018] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.
[0019] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0020] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0021] First of all, it should be noted that Figure 1 and Figure 2 These are two separate figures, which are actually a whole. In order to make the readers understand the connection between the two figures, the pressure stabilizing tank, the second pressure gauge, the three-way valve, and the drain pipe are shown in both figures.
[0022] like Figure 1 As shown, an air conditioning air supply humidification device includes a water tank 5 connected to a water supply pipeline 1, an electric valve 3 is provided on the water supply pipeline, an electromagnetic level gauge 6 for detecting the water level is provided on the water tank, and a PLC 7 for controlling the operation of the electric valve based on the liquid level is electrically connected to the electromagnetic level gauge and the electric valve respectively; it also includes a first liquid delivery pipeline connected to the water tank, an independent water pump 10, a filter element 11, and a first pressure gauge 12 are sequentially provided on the first liquid delivery pipeline; the independent water pump is connected to the frequency converter ( Figure 1The rectangular module beside the PLC is electrically connected, and the PLC for controlling the rotating speed of the independent water pump through the frequency converter based on the pressure detected from the first pressure gauge is electrically connected with the first pressure gauge; the air conditioning air supply and humidification device further comprises a pressure stabilizing tank 13 for ensuring that the water pressure at the water inlet of the high-pressure micro-fog humidifier meets the standard when a leakage point occurs in the front-end various pipelines, and the pressure stabilizing tank is in communication with the first liquid conveying pipeline; the pressure stabilizing tank is in communication with the high-pressure micro-fog humidifier 17 through a second liquid conveying pipeline, and a three-way valve 15 is arranged on the second liquid conveying pipeline, and the three-way valve is provided with a water drain pipe 16 for draining water in the high-pressure micro-fog humidifier when the rear-end high-pressure micro-fog humidifier fails; the air conditioning air supply device further comprises an atomizing frame fixed in the air conditioning humidification section, and the atomizing frame is provided with a high-pressure micro-fog nozzle 32 for spraying humidification water droplets, and the atomizing frame is made of stainless steel; the high-pressure micro-fog humidifier is in communication with the atomizing frame in the air conditioning humidification section through a plastic hose, and an electromagnetic valve is arranged on the plastic hose.
[0023] In some embodiments, a second pressure gauge 14 for monitoring the operating state of the pressure stabilizing tank is further included.
[0024] In some embodiments, a magnetic float level gauge 4 for judging the actual water level in the water tank is arranged on the water tank.
[0025] In some embodiments, a manual valve 2 for controlling the opening and closing of the water replenishment pipeline is further included.
[0026] In some embodiments, an overflow pipe 8 for discharging excess water to a wastewater recovery system when the electric valve fails to cause excessive water replenishment of the water tank is further arranged on the water tank.
[0027] In some embodiments, a blowdown pipe 9 for emptying the water in the water tank is further arranged on the water tank.
[0028] In some embodiments, the electromagnetic valve comprises a first electromagnetic valve 18, a second electromagnetic valve 19, and a third electromagnetic valve 20; the first electromagnetic valve, the second electromagnetic valve, and the third electromagnetic valve are respectively in communication with the control unit in the high-pressure micro-fog humidifier through the plastic hose. Figure 2The first solenoid valve is communicated with the first horizontal pipe through the first plastic hose, the second solenoid valve is communicated with the second horizontal pipe through the second plastic hose, and the third solenoid valve is communicated with the third horizontal pipe through the third plastic hose.
[0029] As shown in Figure 1 The water level in the water tank is detected by an electromagnetic liquid level meter, and the PLC acquires the water level. The PLC determines whether the current water level has reached a required water level. If not, the electric valve is controlled to perform an opening operation. Tap water passes through a water supplement pipeline, passes through a manual valve, and enters the water tank through the electric valve to reach the required water level. After a period of time, if the PLC detects that the current water level has reached the required water level by means of the electromagnetic liquid level meter, the electric valve is controlled to perform a closing operation to stop adding water to the water tank.
[0030] When the electric valve fails to close and cannot be detected in time, causing the water tank to be excessively supplemented with water, the excess water is discharged through an overflow pipe to a wastewater recycling system for reuse. The overflow pipe prevents water from overflowing from the opening at the top of the water tank to the air conditioning machine room, causing flooding.
[0031] When the water tank needs to be maintained and cleaned, the manual valve on the blowdown pipe is opened to empty the water in the water tank, facilitating maintenance personnel to perform maintenance tasks.
[0032] The magnetic reed liquid level meter provided on the water tank facilitates workers to observe the real-time water level in the water tank and serves as evidence for determining the real water level in the water tank.
[0033] As shown in Figure 1 The water pressure in the first liquid delivery pipeline is detected by a first pressure gauge. When the water pressure is too high, the PLC controls the rotation speed of the independent water pump by means of a frequency converter to stop the rotation of the independent water pump, i.e., to stop the pump. When the water pressure is too low, the independent water pump is started to ensure constant-pressure water supply.
[0034] Because the water for supplementing or in use is tap water, which generally contains many impurities, a filter element is provided to filter the tap water, ensuring the cleanliness of the water source and avoiding the failure of the water pump in the high-pressure micro-fog humidifier to operate normally.
[0035] The pressure stabilizing tank is arranged to ensure the constant water pressure of the high-pressure micro-fog humidifier when the water leakage occurs in the front end of the high-pressure micro-fog humidifier.
[0036] The second pressure gauge is arranged to detect the water pressure in the front end of the high-pressure micro-fog humidifier, monitor the operation state of the pressure stabilizing tank, and monitor the water pressure state when the high-pressure micro-fog humidifier in the rear end operates or fails, so as to exclude the failure of the water pressure instability in the front and rear ends.
[0037] The three-way valve is arranged to control the drainage of the drain pipe, so as to drain the water in the high-pressure micro-fog humidifier when the high-pressure micro-fog humidifier in the rear end fails, and facilitate the maintenance of the high-pressure micro-fog humidifier in the rear end.
[0038] As described above, the humidification process of the air conditioner supply air in the air conditioning humidification section 24 at the end is stated next.
[0039] According to the specific requirements, the opening or closing of the first electromagnetic valve, the second electromagnetic valve, and the third electromagnetic valve is controlled. Specifically, if 30% of the micro-fog needs to be opened, only the first electromagnetic valve needs to be opened. If 60% of the micro-fog needs to be opened, the first electromagnetic valve and the second electromagnetic valve need to be opened. If 100% of the micro-fog needs to be opened, the first electromagnetic valve, the second electromagnetic valve, and the third electromagnetic valve all need to be opened.
[0040] Please note that, from the perspective of cost, the first plastic hose, the second plastic hose, and the third plastic hose are made of general hose pipes, because even if there is a breakage and water leakage, the staff can discover it in time. However, the atomizing frame inside the air conditioning humidification section 24 is made of stainless steel, because it is difficult to discover the problem of the water droplet ejection unit inside. Therefore, in some embodiments, the atomizing frame is made of stainless steel, so as to balance the cost and technical effect, and ensure that the device can be used for a long time.
[0041] It can be further stated that the atomizing frame is customized according to the size of the air handling unit / air duct, and includes a first horizontal pipe, a second horizontal pipe, and a third horizontal pipe, and a first vertical pipe, a second vertical pipe, a third vertical pipe, and a fourth vertical pipe. The first horizontal pipe, the second horizontal pipe, and the third horizontal pipe are arranged perpendicularly with the first vertical pipe, the second vertical pipe, the third vertical pipe, and the fourth vertical pipe, and the intersection is a high-pressure micro-fog nozzle for spraying humidification water droplets. The stainless steel material of the atomizing frame and the absence of obvious connections ensure the water pressure and sealing performance.
[0042] The high-pressure micro-fog nozzle produces very uniform water droplets with an average diameter of 10-15 μm after being supplied with pressurized water, and the water droplets can be easily absorbed by air.
[0043] The air supply and humidification device of the present disclosure is equivalent to adding a water supplement system, which avoids the disadvantage of unstable water pressure caused by the original water supplement system and avoids the failure shutdown of the high-pressure micro-fog humidifier in the air supply and humidification device. In addition, over time, water leakage may occur at the hose joint, which may further cause the failure shutdown of the high-pressure micro-fog humidifier in the air supply and humidification device. However, by changing the outlet hose to a hard pipe of the atomizing rack made of stainless steel, this problem is effectively solved.
[0044] The technical means adopted by the present disclosure can effectively improve the stability of air supply and humidification, and provide guarantee for the quality of cigarette production.
[0045] Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the present disclosure. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
