Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, in particular to a tobacco odor treatment system. Background Art

[0002] During the production process of each tobacco enterprise, the odor waste gas generated is generally treated by an odor treatment system to eliminate the odor and particulate dust and meet the environmental protection requirements before being discharged.

[0003] Currently, when treating the odor waste gas in the tobacco production process, alkaline substances are usually manually added to the water in the waste gas treatment pool to ensure the acidity and alkalinity of the water quality in the waste gas treatment pool, and then the odor waste gas incorporated into the waste gas treatment pool is neutralized. However, such a treatment method has problems of low odor treatment efficiency, poor odor treatment effect, and labor consumption.

[0004] In order to solve the above problems, it is necessary to improve the tobacco odor treatment system. Summary of the Invention

[0005] The utility model provides a tobacco odor treatment system to solve the problems of low treatment efficiency of odor waste gas in the tobacco production process, non-compliance of waste gas emissions, and labor consumption in the process of treating odor waste gas in the prior art.

[0006] In a first aspect, an embodiment of the utility model provides a tobacco odor treatment system, including:

[0007] An alkaline water tank treatment subsystem, an exhaust gas filtration subsystem, and a tobacco odor treatment subsystem; wherein,

[0008] The alkaline water tank treatment subsystem is used for performing alkaline treatment on the water in the alkaline water tank to obtain alkaline water with a pH value of alkalinity;

[0009] The exhaust gas filtration subsystem is used for filtering the particulate matter in the odor waste gas when receiving the odor waste gas in the tobacco production process to obtain the waste gas to be treated;

[0010] The tobacco odor treatment subsystem is used for receiving the alkaline water conveyed by the alkaline water tank treatment subsystem and performing tobacco odor treatment on the waste gas to be treated based on the alkaline water after receiving the waste gas to be treated conveyed by the exhaust gas filtration subsystem.

[0011] The technical solution of the embodiment of the present utility model includes an alkaline water tank treatment subsystem, an exhaust gas filtration subsystem, and a tobacco odor treatment subsystem. Among them, the alkaline water tank treatment subsystem is used to perform alkaline treatment on the water in the alkaline water tank to obtain alkaline water with an alkaline pH value; the exhaust gas filtration subsystem is used to filter the particulate matter in the odor exhaust gas when receiving the odor exhaust gas in the tobacco production process to obtain the exhaust gas to be treated; the tobacco odor treatment subsystem is used to receive the alkaline water conveyed by the alkaline water tank treatment subsystem, and based on the alkaline water, perform tobacco odor treatment on the exhaust gas to be treated after receiving the exhaust gas to be treated conveyed by the exhaust gas filtration subsystem. In this technical solution, by setting up the alkaline water tank treatment subsystem, alkaline substances can be directly dissolved to obtain alkaline water. Further, when alkaline substances need to be added to the tobacco odor treatment subsystem, the alkaline water is directly added to the tobacco odor treatment subsystem. That is to say, in the tobacco odor treatment subsystem, there is no need to dissolve the alkaline substances again, but directly use the alkaline water to perform acid-base neutralization on the acidic substances in the odor exhaust gas during the tobacco production process, which can not only improve the treatment efficiency of the odor exhaust gas and enhance the treatment effect of the odor exhaust gas in the tobacco production process. At the same time, this technical solution can also solve the problem in the prior art that when directly adding undissolved alkaline substances to the tobacco odor treatment subsystem, there are too many precipitate substances in the tobacco odor treatment subsystem due to incomplete dissolution of the alkaline substances, and the water in the tobacco odor treatment subsystem needs to be replaced frequently. It prolongs the replacement time of the water in the tobacco odor treatment subsystem, thereby reducing the maintenance cost of manpower in the tobacco odor treatment process.

[0018] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described here can be implemented in an order different from those illustrated or described here.

[0019] Embodiment 1

[0020] Figure 1 A schematic diagram of a tobacco odor treatment system is provided for the present utility model. This embodiment is applicable to the situation where the odor exhaust gas generated in the tobacco production process is incorporated into the exhaust gas treatment pool, and after neutralizing the acidic substances in the odor exhaust gas, the odor exhaust gas can meet the exhaust gas emission standards after treatment. This system can be executed by the tobacco odor treatment system.

[0021] As Figure 1 shown, the system includes: an alkaline water tank treatment subsystem A, an exhaust gas filtration subsystem B, and a tobacco odor treatment subsystem C. This system can be applied to treat the odor exhaust gas discharged in the tobacco production process so that the discharged odor exhaust gas can meet the current exhaust gas environmental protection standards.

[0022] Among them, the alkaline water tank treatment subsystem A is used to perform alkaline treatment on the water in the alkaline water tank to obtain alkaline water with a pH value of alkaline; the exhaust gas filtration subsystem B is used to filter the particulate matter in the odor exhaust gas when receiving the odor exhaust gas in the tobacco production process to obtain the exhaust gas to be treated; the tobacco odor treatment subsystem C is used to receive the alkaline water transported by the alkaline water tank treatment subsystem A, and after receiving the exhaust gas to be treated transported by the exhaust gas filtration subsystem B, perform tobacco odor treatment on the exhaust gas to be treated based on the alkaline water.

[0023] In this practical application, the odor-containing waste gas generated during the production process of each tobacco enterprise generally needs to be treated by an odor treatment system to eliminate odors and particulate dust, and then discharged to meet environmental protection requirements. During the treatment of the odor-containing waste gas, it is necessary to first filter the particulate matter in the odor-containing waste gas and integrate the filtered waste gas into the waste gas treatment water tank. Since the odor-containing waste gas is usually acidic, as the odor-containing waste gas in the waste gas treatment water tank increases, the water quality in the waste gas treatment water tank becomes acidic and cannot meet the waste gas treatment standards. Therefore, in order to make the odor-containing waste gas meet the discharge standards after being treated in the waste gas treatment system, it is necessary to neutralize the acidic water in the waste gas treatment system before discharging it.

[0024] In the prior art, when treating the odor-containing waste gas during the tobacco production process, it is usually necessary to manually add alkaline substances to the waste gas treatment water tank to maintain the acid-base balance of the water quality in the waste gas treatment tank. However, such a treatment method has problems such as insufficient dissolution of alkaline substances, low manual treatment efficiency, and poor odor treatment effect. At the same time, since the water in the waste gas treatment water tank needs to be replaced regularly, otherwise, as the scale increases, the treatment efficiency of the odor treatment system for the odor-containing waste gas during the tobacco production process will decrease, and the labor maintenance cost will also increase.

[0025] Based on this, in the tobacco odor treatment system of this technical solution, an alkaline water tank treatment subsystem A is set up, as Figure 2As shown, the alkaline water pool treatment subsystem A includes a total water inlet stop valve A1 and a total water replenishment ball valve A2; wherein the total water inlet stop valve A1 is used to start or shut down the water inlet of the alkaline water pool treatment subsystem A; the total water replenishment ball valve A2 is used to start the total water inlet stop valve A1 and open the total water replenishment ball valve A2 when it is detected that the water level in the alkaline water pool treatment subsystem A is lower than the total water replenishment ball valve A2, or to close the total water replenishment ball valve A2 when the water level in the alkaline water pool treatment subsystem A is higher than the total water replenishment ball valve A2. The alkaline water pool treatment subsystem A includes an alkali powder feeding port A3, which is used to add alkaline substances to the alkaline water pool treatment subsystem A when the pH value of the water quality in the alkaline water pool treatment subsystem A is lower than the preset pH value, so as to make the pH value of the water quality in the alkaline water pool treatment subsystem A alkaline. The alkaline water pool treatment subsystem A includes a first stirrer A4, which is used to stir the water in the alkaline water quality treatment subsystem when adding alkaline substances to the alkaline water pool treatment subsystem A to accelerate the dissolution of the alkaline substances. The alkaline water pool treatment subsystem A includes: a first pH value detector A5 and a pH value early warning module A6; wherein the first pH value detector A5 is used to detect the pH value of the water in the alkaline water pool treatment subsystem A to obtain the current pH value of the water quality in the alkaline water pool treatment subsystem A; the pH value early warning module A6 is used to issue an early warning when the current pH value is lower than a preset pH value, so as to prompt the target user to add alkaline substances to the alkaline water pool treatment subsystem A.

[0026] In practical applications, in order to ensure that the water quality in the alkaline water pool treatment subsystem A remains alkaline, it is necessary to adjust the pH of the water in the alkaline water pool treatment subsystem A according to the pH value of the water quality in the alkaline water pool treatment subsystem A. Specifically, when it is necessary to add alkaline substances to the alkaline water pool treatment subsystem A, alkaline powder or chemical reagents for adjusting the water quality to alkaline can be added to the alkaline water pool treatment subsystem A through the alkaline powder feeding port A3 provided on the alkaline water pool treatment subsystem A. Further, after the alkaline substances are added, the water in the alkaline water pool treatment subsystem A is stirred by the first agitator A4 provided inside the alkaline treatment water pool subsystem to accelerate the dissolution of the newly added alkaline substances.

[0027] The advantage of this arrangement is that the first agitator A4 helps to form water convection in the alkaline water tank treatment subsystem A, greatly improving the dissolution efficiency of the alkaline substance during the dissolution process, reducing the presence of a large amount of alkaline precipitates due to insufficient dissolution of the alkaline substance in the alkaline water tank treatment subsystem A, and by fully dissolving the alkaline substance, better maintaining the pH value in the alkaline treatment water tank subsystem, thereby improving the treatment effect of odorous waste gas in the tobacco production process.

[0028] On this basis, a total inlet shut-off valve A1 is also provided in the alkaline water tank treatment subsystem A, which is used to start or close the water inlet of the alkaline water tank treatment subsystem A; a total water replenishment ball valve A2, which is used to open the total water replenishment ball valve A2 when the total inlet shut-off valve A1 is started and the water level in the alkaline water tank treatment subsystem A is detected to be lower than the total water replenishment ball valve A2, or to close the total water replenishment ball valve A2 when the water level in the alkaline water tank treatment subsystem A is higher than the total water replenishment ball valve A2.

[0029] On this basis, a first pH detector A5 and a pH warning module A6 are also provided in the alkaline water tank treatment subsystem A. Among them, the first pH detector A5 is used to detect the pH value in the alkaline water tank treatment subsystem A. When the pH value is less than the preset pH value, a warning prompt is given through the pH warning module A6 to prompt the target user (such as, the working user) to add alkaline substances to the alkaline water tank treatment subsystem A to keep the acidity and alkalinity of the water in the alkaline water tank treatment subsystem A balanced.

[0030] On this basis, the tobacco odor treatment system in this technical solution further includes an exhaust gas filtration subsystem B, and the exhaust gas filtration subsystem B is used to filter the particulate matter in the odor exhaust gas when receiving the odor exhaust gas in the tobacco production process to obtain the exhaust gas to be treated. Among them, the exhaust gas filtration subsystem B includes a particulate matter filter B1, and the particulate matter filter B1 is used to adsorb and filter the particulate matter in the odor exhaust gas.

[0031] Specifically, a particulate matter filter is provided in the exhaust gas filtration subsystem B. For example, the particulate matter filter can be a wreathed packing, which is used to filter the particulate matter in the odor exhaust gas in the tobacco production process. Among them, the wreathed packing can be a PP Taylor wreathed packing. The advantage of this packing is that the wreathed packing has a large porosity and is not easily blocked, and also has advantages such as a large throughput and a small resistance. Since there can be a relatively high liquid holdup at the gaps of this wreathed packing, the liquid in the exhaust gas can stay for a longer time, thereby increasing the gas-liquid contact time and improving the filtration efficiency of the particulate matter. In practical applications, users can select different materials such as polypropylene (PP), RPP (glass fiber reinforced polypropylene), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinylidene fluoride (PVDF), etc. plastic wreathed packings according to the usage conditions (such as temperature, pressure, medium, etc.) in the exhaust gas filtration subsystem B.

[0032] Furthermore, the tobacco odor treatment system of this technical solution further includes a tobacco odor treatment subsystem C, and a water pump and a water pipe are arranged between the tobacco odor treatment subsystem C and the alkaline water tank treatment subsystem A for transporting the alkaline water in the alkaline water tank treatment subsystem A to the tobacco odor treatment subsystem C. And the exhaust gas filtration subsystem B and the tobacco odor treatment subsystem C are connected through a ventilation duct to obtain an exhaust gas treatment subsystem, and the number of the exhaust gas treatment subsystems is set to one or more according to the exhaust gas volume of the odor exhaust gas in the tobacco production process.

[0033] In practical applications, when treating the odor exhaust gas in the tobacco production process, the odor exhaust gas first passes through the particulate matter filtration of the exhaust gas filtration subsystem B, and further transports the filtered odor exhaust gas to the tobacco odor treatment subsystem C through the ventilation duct between the exhaust gas filtration subsystem B and the tobacco odor treatment subsystem C, so that the odor exhaust gas is integrated into the alkaline water in the tobacco odor treatment subsystem C, thereby performing acid-base neutralization on the acidic substances in the odor exhaust gas to meet the exhaust gas emission standards.

[0034] Furthermore, in this technical solution, by installing a second pH detector C1, a solenoid valve C2, and a second stirrer C3 in the tobacco odor treatment subsystem C, the acid-base balance of the water quality in the tobacco odor treatment subsystem C is maintained. As Figure 3 shown, among them, the second pH detector C1 is used to detect the pH value of the water in the tobacco odor treatment subsystem C and give an abnormal pH value prompt when the pH value is lower than the preset pH value; the solenoid valve C2 is used to open when receiving the abnormal pH value prompt to automatically input the alkaline water in the alkaline water tank treatment subsystem A into the tobacco odor treatment subsystem C; the second stirrer C3 is used to stir the alkaline water and the un-neutralized acidic water in the tobacco odor treatment subsystem C to neutralize the pH value of the water in the tobacco odor treatment subsystem C. The tobacco odor treatment subsystem C is provided with an overflow port C4 for overflowing the water exceeding the installation height of the overflow port C4 from the tobacco odor treatment subsystem C when the water in the tobacco odor treatment subsystem C exceeds the installation height of the overflow port C4.

[0035] Specifically, the water quality in the tobacco odor treatment subsystem C needs to be alkaline to ensure that after the odor exhaust gas carrying acidic substances is incorporated into the water in the tobacco odor treatment subsystem C, the acidic substances in the odor exhaust gas can be neutralized. Based on this, the second pH detector C1 installed in the tobacco odor treatment subsystem C can monitor the pH value of the water quality in the tobacco odor treatment subsystem C in real time. When the current pH value in the tobacco odor treatment subsystem C is lower than the preset pH value, the solenoid valve C2 is opened so that the alkaline water in the alkaline water tank treatment subsystem A can be transported to the tobacco odor treatment subsystem C through the water pump and water pipe between the alkaline water tank treatment subsystem A and the tobacco odor treatment subsystem C. At the same time, the second stirrer C3 is turned on to fully neutralize the acidic and alkaline substances in the tobacco odor treatment subsystem C. After the solenoid valve C2 is opened for a period of time, it is closed, and the pH value of the water quality in the tobacco odor treatment subsystem C is detected again based on the second pH detector C1 until the current pH value is greater than the preset pH value, then the water pump and water pipe between the alkaline water tank treatment subsystem A and the tobacco odor treatment subsystem C are closed, and the transportation of alkaline water to the tobacco odor treatment subsystem is stopped.

[0036] It should be noted that in this technical solution, the exhaust gas filtration subsystem and the tobacco odor treatment subsystem are connected through a ventilation duct to obtain an exhaust gas treatment subsystem. Referring again to Figure 1 , taking the number of exhaust gas treatment subsystems as 2 as an example, in actual application, due to the different amounts of odor exhaust gas in the tobacco production process, the number of activated exhaust gas treatment subsystems is determined. When the amount of odor exhaust gas is small, only the alkaline water tank treatment subsystem and a group of exhaust gas treatment subsystems (where the exhaust gas treatment subsystem includes an exhaust gas filtration subsystem and a tobacco odor treatment subsystem) can be activated. However, when the amount of odor exhaust gas is large, a single group of exhaust gas treatment subsystems cannot fully neutralize the odor exhaust gas. Therefore, when the amount of odor exhaust gas is large, according to the actual situation, the alkaline water tank treatment subsystem and at least two groups of exhaust gas treatment subsystems can be activated to ensure that the odor exhaust gas in the tobacco production process can meet the exhaust gas treatment standard.

[0037] Specifically, during the tobacco production process, if the alkaline water tank treatment subsystem and at least two sets of waste gas treatment subsystems are started simultaneously, adjacent waste gas treatment subsystems can be connected through ventilation ducts, so that after the odor-containing waste gas passes through the first set of waste gas treatment subsystems, the odor-containing waste gas is conveyed to the second set of waste gas treatment subsystems through the ventilation ducts, and so on, and the odor-containing waste gas can be conveyed to each started waste gas treatment subsystem. Further, through the water pumps and water pipes between the alkaline water tank treatment subsystem and each waste gas treatment subsystem, the alkaline water in the alkaline water tank treatment subsystem is conveyed to each waste gas treatment subsystem, so as to perform acid-base neutralization treatment on the odor-containing waste gas in each waste gas treatment subsystem based on the alkaline water, so that the odor-containing waste gas meets the waste gas emission standards after being treated.

[0038] The technical solution of the embodiment of the present invention includes an alkaline water tank treatment subsystem, a waste gas filtration subsystem, and a tobacco odor treatment subsystem; wherein, the alkaline water tank treatment subsystem is used to perform alkaline treatment on the water in the alkaline water tank to obtain alkaline water with an alkaline pH value; the waste gas filtration subsystem is used to filter the particulate matter in the odor-containing waste gas when receiving the odor-containing waste gas during the tobacco production process to obtain the waste gas to be treated; the tobacco odor treatment subsystem is used to receive the alkaline water conveyed by the alkaline water tank treatment subsystem, and based on the alkaline water, perform tobacco odor treatment on the waste gas to be treated after receiving the waste gas to be treated conveyed by the waste gas filtration subsystem. In this technical solution, by setting up the alkaline water tank treatment subsystem, alkaline substances can be directly dissolved to obtain alkaline water. Further, when alkaline substances need to be added to the tobacco odor treatment subsystem, the alkaline water is directly added to the tobacco odor treatment subsystem. That is to say, in the tobacco odor treatment subsystem, it is no longer necessary to dissolve the alkaline substances, but directly perform acid-base neutralization on the acidic substances in the odor-containing waste gas during the tobacco production process through the alkaline water, which can not only improve the treatment efficiency of the odor-containing waste gas and enhance the treatment effect of the odor-containing waste gas during the tobacco production process. At the same time, this technical solution can also solve the problem in the prior art that when directly adding undissolved alkaline substances to the tobacco odor treatment subsystem, there are too many precipitates in the tobacco odor treatment subsystem due to incomplete dissolution of the alkaline substances, and the water in the tobacco odor treatment subsystem needs to be replaced frequently, extending the replacement time of the water in the tobacco odor treatment subsystem, thereby reducing the maintenance cost of manpower in the tobacco odor treatment process.

[0039] It should be understood that the various forms of processes shown above can be used, steps can be reordered, added, or deleted. For example, the steps described in the present invention can be executed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved, and no limitations are imposed herein.

[0040] The above specific embodiments do not constitute a limitation to the protection scope of the present utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
