Fig. 1 schematically illustrates the construction of the tobacco-producing exhaust treatment system of the present application.

Referring to fig. 1, in the present application, a tobacco process exhaust treatment system 100 includes an odor treatment apparatus 101 and a water supply 102. Wherein the odor treatment apparatus 101 is used for washing the exhaust gas discharged from the tobacco production apparatus (not shown) with water to remove the odor in the exhaust gas. The water supply system 102 is used for providing water for washing the tobacco production waste gas treatment system 100, and comprises a reclaimed water supply system 103, wherein the reclaimed water supply system 103 is connected with the reclaimed water source 200 and the peculiar smell treatment device 101 so as to supply reclaimed water of the reclaimed water source 200 to the peculiar smell treatment device 101.

By providing the reclaimed water supply system 103, the odor treatment apparatus 101 is supplied with reclaimed water such that the water used by the odor treatment apparatus 101 to wash the tobacco process waste gas can no longer come from, at least not all of, the tap water, but can come from the reclaimed water.

Because reclaimed water is reclaimed water, compared with tap water, the cost is lower, and the energy conservation and emission reduction are facilitated, so that the return water is utilized to treat the peculiar smell of the tobacco production waste gas, and the waste of water resources of the tobacco production waste gas can be reduced and the cost is reduced on the basis of meeting the daily water requirement of the peculiar smell treatment equipment 101.

In addition, the recycling of reclaimed water can be realized, so that the recycling efficiency of reclaimed water is improved, energy conservation and emission reduction are realized, and the influence of direct discharged reclaimed water on municipal official networks is reduced.

Therefore, the tobacco production waste gas treatment system 100 provided by the application can save energy, reduce emission and reduce cost on the basis of meeting the normal water use of the peculiar smell treatment equipment 101.

As an example of the reclaimed water supply system 103, referring to fig. 1, the reclaimed water supply system 103 includes a water inlet pipe 1, a water tank 2, and a water outlet pipe 6, the water tank 2 is connected to the reclaimed water source 200 through the water inlet pipe 1 and to the odor treatment apparatus 101 through the water outlet pipe 6, so that reclaimed water of the reclaimed water source 200 enters the water tank 2 via the water inlet pipe 1 and flows from the water tank 2 into the odor treatment apparatus 101 via the water outlet pipe 6.

In the above-described aspect, the water tank 2 can store the reclaimed water, so that the reclaimed water supply system 103 can supply the reclaimed water to the odor treatment apparatus 101 more stably.

Furthermore, the provision of the water tank 2 also facilitates the monitoring of the supplied reclaimed water before it is supplied to the odor treatment apparatus 101, to better meet the requirements of the odor treatment apparatus 101.

For example, referring to fig. 1, in some embodiments, the reclaimed water supply system 103 includes not only the aforementioned water inlet pipe 1, the water tank 2, and the water outlet pipe 6, but also the water quality detecting device 3, the water quality detecting device 3 detecting whether the quality of reclaimed water in the water tank 2 is acceptable, and the reclaimed water supply system 103 supplying reclaimed water to the odor treatment apparatus 101 when the water quality detecting device 3 detects that the quality of reclaimed water in the water tank 2 is acceptable. In this way, the reclaimed water supply system 103 can supply only reclaimed water with qualified water quality to the odor treatment apparatus 101, so as not to influence the odor treatment effect of the odor treatment apparatus 101 due to unqualified reclaimed water quality. In general, the odor treatment apparatus 101 requires that the OPR (oxidation-reduction potential, reflecting macroscopic redox properties exhibited by all substances in an aqueous solution) of water for washing is more than 400mv, and the turbidity is less than 30mv, that is, when the OPR of supplied water is more than 400mv and the turbidity is less than 30mv, it means that the quality of supplied water is acceptable and normal.

In order to realize the water quality detection function of the water quality detection device 3, referring to fig. 1, in some embodiments, the water quality detection device 3 includes a water quality sensor 31 and a water quality monitor 32, the water quality sensor 31 extends into the water tank 2 to detect the quality of reclaimed water in the water tank 2, and the water quality monitor 32 is in signal connection with the water quality sensor 31 to determine whether the quality of reclaimed water detected by the water quality sensor 31 is acceptable. In this way, the quality of the reclaimed water in the water tank 2 is detected by the water quality sensor 31, and the detection result is transmitted to the water quality monitor 32 for analysis, so that whether the quality of the reclaimed water in the water tank 2 is qualified can be determined, and a required water quality detection function is realized, so as to control whether the reclaimed water supply system 103 supplies the reclaimed water to the odor treatment equipment 101.

In addition, for convenience in controlling the reclaimed water supply system 103, referring to fig. 1, in some embodiments, the reclaimed water supply system 103 includes not only the aforementioned water inlet pipe 1, the water tank 2, and the water outlet pipe 6, but also at least one of the water inlet valve 14, the control valve 11, the water outlet valve 61, the first filter 13, the second filter 62, the booster pump 63, the pressure gauge 64, the first check valve 65, the liquid level gauge 4, and the water meter 12.

Wherein, the water inlet valve 14 is arranged on the water inlet pipe 1 and controls the on-off of the water inlet pipe 1. In this way, whether the reclaimed water is introduced into the water tank 2 can be controlled by controlling the opening and closing of the water inlet valve 14, so that the reclaimed water level in the water tank 2 is prevented from being too low or too high, and the normal operation of the reclaimed water supply system 103 is not affected. Wherein the inlet valve 14 may be a manual valve or an electrically controlled valve. When the water inlet valve 14 is an electric control valve, the degree of automation is higher, and the opening and closing control of the water inlet valve 14 is more convenient.

The control valve 11 is arranged on the water inlet pipe 1 and controls the on-off of the water inlet pipe 1. In this way, whether or not to supply the reclaimed water into the water tank 2 can be controlled by controlling the opening and closing of the control valve 11. The control valve 11 may be a manual valve or an electric control valve. In the case that the water inlet valve 14 and the control valve 11 are simultaneously arranged on the water inlet pipe 1, the control valve 11 and the water inlet valve 14 can be mutually standby, so that the protection effect is increased, the working reliability is improved, and one of the water inlet valves is prevented from leaking, so that water leakage is caused.

The water outlet valve 61 is arranged on the water outlet pipe 6 and controls the on-off of the water outlet pipe 6. In this way, by controlling the opening and closing of the water outlet valve 61, it is possible to control whether the reclaimed water in the water tank 2 is supplied to the odor treatment apparatus 101, and thus whether the reclaimed water is supplied to the odor treatment apparatus 101, so that it is convenient to control the reclaimed water supply system 103 to supply the reclaimed water to the odor treatment apparatus 101 only under the condition that the condition is appropriate (for example, the quality of the reclaimed water is acceptable and the liquid level in the water tank 2 is appropriate), so as to better satisfy the water demand of the odor treatment apparatus 101. The water outlet valve 61 may be a manual valve or an electric control valve. When the outlet valve 61 is an electric control valve, the degree of automation is higher, and the opening and closing control of the outlet valve 61 is more convenient.

In this way, the purity of the reclaimed water flowing into the water tank 2 can be improved, the influence of impurities in the reclaimed water on downstream structural components can be reduced, and the operational reliability of the reclaimed water supply system 103 can be improved.

A second filter 62 is provided on the outlet pipe 6 to filter the reclaimed water flowing from the water tank 2 to the odor treatment apparatus 101. In this way, the purity of the water supplied to the odor treatment apparatus 101 can be improved, thereby better meeting the water demand of the odor treatment apparatus 101.

A booster pump 63 is provided on the water outlet pipe 6 to boost the pressure of the medium water flowing from the water tank 2 to the odor treatment apparatus 101.

A pressure gauge 64 is provided on the outlet pipe 6 to detect the pressure of the medium water flowing from the water tank 2 to the odor treatment apparatus 101. In this way, the pressure of the reclaimed water flowing to the odor treatment apparatus 101 can be detected, and the reclaimed water pressure supplied to the odor treatment apparatus 101 can be conveniently and accurately controlled.

A first one-way valve 65 is provided on the outlet pipe 6 to control the one-way flow of water from the tank 2 to the odour treatment apparatus 101. Thus, the reverse flow of the reclaimed water can be prevented, and the water supply reliability of the reclaimed water supply system 103 can be improved.

The level gauge 4 detects the level of the reclaimed water in the tank 2. Therefore, the liquid level in the water tank 2 can be detected, the liquid level condition in the water tank 2 can be conveniently and accurately known in real time, and the water in the water tank 2 is effectively prevented from being too little or too much.

The water meter 12 is provided on the water inlet pipe 1 to detect the amount of reclaimed water flowing into the water tank 2. In this way, monitoring the amount of reclaimed water in the reclaimed water supply system 103 is facilitated.

Furthermore, referring to fig. 1, in some embodiments, the reclaimed water supply system 103 includes not only the aforementioned water inlet pipe 1, the water tank 2, and the water outlet pipe 6, but also a drain pipe 51 and a drain valve 52, the drain pipe 51 is connected with the water tank 2, and the drain valve 52 is disposed on the drain pipe 51, and controls whether to drain reclaimed water in the water tank 2 by controlling the on-off of the drain pipe 51. Thus, the sewage in the middle water tank 2 can be discharged in time so as to replace the middle water and improve the quality of the middle water.

As a further improvement to the foregoing embodiments, referring to fig. 1, in some embodiments, the water supply system 102 includes not only the reclaimed water supply system 103, but also a tap water supply system 104, the tap water supply system 104 connecting a tap water source 300 with the odor treatment apparatus 101 to supply tap water to the odor treatment apparatus 101. In this way, the water supply system 102 not only can supply the reclaimed water to the odor treatment device 101, but also can supply tap water to the odor treatment device 101, so that different water supply modes can be flexibly selected according to actual conditions, and the water demand of the odor treatment device 101 can be better met.

As an example of the tap water supply system 104, referring to fig. 1, in some embodiments, the tap water supply system 104 includes a water supply pipe 7 and a water supply valve 71, the water supply pipe 7 connects the tap water source 300 with the odor treatment apparatus 101, and the water supply valve 71 is provided on the water supply pipe 7 and controls on-off of the water supply pipe 7. In this way, whether the tap water supply system 104 supplies tap water to the odor treatment apparatus 101 can be controlled by controlling the opening and closing of the water supply valve 71, so that the water supply system 102 can be conveniently controlled to supply tap water to the odor treatment apparatus 101 only when the reclaimed water supply system 103 cannot meet the water demand of the odor treatment apparatus 101, so that the waste of water resources is reduced as much as possible when the normal water demand of the odor treatment apparatus 101 is met.

Also, referring to fig. 1, in some embodiments, the tap water supply system 104 includes not only the water supply pipe 7 and the water supply valve 71, but also a second check valve 72, the second check valve 72 being provided on the water supply pipe 7 to control the one-way flow of tap water from the tap water source 300 to the odor treatment apparatus 101. Thus, the reverse flow of the tap water can be prevented, and the water supply reliability of the tap water supply system 104 can be improved.

The present application will be further described with reference to the embodiment shown in fig. 1.

The control valve 11, the water meter 12, the first filter 13 and the water inlet valve 14 are sequentially arranged on the water inlet pipe 1 along the flowing direction of the reclaimed water so as to control the on-off of the water inlet pipe 1 and filter and monitor the water quantity of the reclaimed water flowing to the water tank 2. The water outlet pipe 6 connects the water tank 2 and the odor treatment apparatus 101. The water outlet valve 61, the second filter 62, the booster pump 63, the pressure gauge 64 and the first check valve 65 are sequentially disposed on the water outlet pipe 6 along the flowing direction of the reclaimed water to control the on-off of the water outlet pipe 6 and to filter, boost pressure, detect pressure and control the flowing direction of the reclaimed water flowing to the odor treatment apparatus 101. The liquid level meter 4 and the drain pipe 51 are both arranged on the water tank 2 and are respectively used for detecting the liquid level and draining. A drain valve 52 is provided on the drain pipe 51 to control whether or not the drain is discharged.

In this embodiment, as shown in fig. 1, both the second check valve 72 and the first check valve 65 are located upstream of the junction of the water supply pipe 7 and the water outlet pipe 6.

Based on the above structure, the water supply system 102 of this embodiment can realize the following operation modes:

(1) Automatic control mode

The water inlet valve 14 is opened, the level gauge 4 detects the level of the reclaimed water, the water quality sensor 31 detects that the quality of the reclaimed water is qualified (ORP is more than 400mv, turbidity is less than 30 mv), the drain valve 52 is closed, the water outlet valve 61 and the booster pump 63 are opened, and the water supply valve 71 is closed, so that the reclaimed water supply system 103 supplies the reclaimed water to the odor treatment apparatus 101.

During the supply of reclaimed water, the water level in the water tank 2 can be controlled by opening and closing the water inlet valve 14. When the liquid level of the water tank 2 reaches the high limit, the water inlet valve 14 is closed, and when the liquid level of the water tank 2 falls to the low limit, the water inlet valve 14 can be opened again to supplement water.

(2) Abnormal water quality mode

The water quality sensor 31 detects abnormality of the reclaimed water quality (ORP is less than 400mv, turbidity is greater than 30 mv), closes the water inlet valve 14, closes the water outlet valve 61 and the booster pump 63, opens the drain valve 52, opens the water supply valve 71 to supply the reclaimed water to the odor treatment apparatus 101 from the tap water supply system 104, and stops the reclaimed water supply, and drains the reclaimed water supply system 103.

In the above process, the water inlet valve 14 may be opened and the drain valve 52 may be closed at regular intervals (for example, 24 hours) to update the reclaimed water in the water tank 2, until the water quality sensor 31 detects that the water quality is normal (ORP is greater than 400mv and turbidity is less than 30 mv), the water outlet valve 61 and the booster pump 63 may be opened, and the water supply valve 71 may be closed to enter the above-described automatic control mode.

(3) Device anomaly mode

When the water level in the detection of the liquid level meter 4 is continuously lower than the low level, the fault of the booster pump 63, the faults of the valves or the abnormality of the water quality sensor 31 for a certain period of time (for example, 5 minutes) occurs, the abnormal equipment mode is entered, the water inlet valve 14, the water outlet valve 61 and the booster pump 63 are closed, the water supply valve 71 is opened, and the tap water supply system 104 supplies tap water to the odor treatment equipment 101.

It can be seen that the system 100 for treating waste gas in tobacco production in this embodiment has a simple structure and convenient use, and in particular, the water supply system 102 can supply reclaimed water or tap water to the odor treatment device 101, and under the condition that the reclaimed water quality is normal and the device has no fault, the reclaimed water is preferentially supplied, and under the condition that the reclaimed water supply system 103 has the device fault, tap water can be supplied, and meanwhile, under the condition that the reclaimed water quality in the water tank 2 is abnormal, the reclaimed water in the water tank 2 can be discharged and changed, so that the reclaimed water quality in the water tank 2 is recovered to be normal, thereby not only effectively meeting the normal water requirement of the odor treatment device 101, but also recycling the reclaimed water, reducing the consumption of tap water by the odor treatment device 101, reducing the cost, saving energy and reducing emission.
