Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf processing, in particular to a tobacco dry distillation cooling, impurity removal and purification device. Background Art

[0002] In recent years, due to the rise of new tobacco products such as electronic cigarettes and low-temperature atomizer cigarettes, the demand for lower heating and atomization temperatures, low harmfulness and strong reducing taste has made distillation one of the important processes for providing aroma substances for new tobacco products. The existing tobacco distillation equipment is basically completed by four major components: a distillation chamber, a collection chamber, a condensing device in the collection chamber and a vacuum pump. By heating the tobacco raw materials in the distillation chamber, high-temperature gas is generated. After this part of the high-temperature gas is collected by the collection chamber, the corresponding tobacco distillation product is obtained.

[0003] During the dry distillation process of tobacco, although a gauze is installed at the position of the airway channel, as the high-temperature gas circulates during the dry distillation process, dust or cracked solid powder particles will inevitably enter the collection chamber with the high-temperature gas. Secondly, even if air is introduced into the dry distillation chamber to minimize the production of black tar during the dry distillation process, small tar droplets will still combine with dust or solid powder particles and enter the collection chamber with the high-temperature gas, reducing the purity of the collected liquid. Therefore, the tobacco dry distillation products often have problems such as unstable physical and chemical indicators and unstable product quality. Utility Model Content

[0004] The purpose of the utility model is to provide a tobacco dry distillation cooling, impurity removal and purification device to solve the problem raised in the above-mentioned background art that although the generation of black tar during the dry distillation process can be minimized by introducing air into the dry distillation chamber, fine tar droplets still combine with dust or solid powder particles and enter the collection chamber with the high-temperature gas, thereby reducing the purity of the collected liquid. As a result, the tobacco dry distillation product often suffers from unstable physical and chemical indicators and unstable product quality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tobacco dry distillation cooling and impurity removal purification device, comprising a purification chamber, the upper surface of the purification chamber is provided with a top cover plate, the surface of the top cover plate is provided with an installation opening, the inner wall of the installation opening is fixedly connected with an air inlet pipe, the lower surface of the top cover plate is fixedly installed with a temperature sensor, a sewage bottom valve is installed at the lower end of the purification chamber, two collecting chambers are sequentially provided on the side of the purification chamber, the upper surface of the collecting chamber is provided with a feed port, the lower surface of the collecting chamber is provided with a discharge port, the surface of the collecting chamber is connected with a liquid level gauge, the upper surface of the collecting chamber is provided with a vacuum pump pipe, the two collecting chambers are connected by a pipeline, and an air guide pipe is installed between the collecting chamber and the purification chamber on one side.

[0007] By adopting the above technical solution, when using the device, raw materials are added to the dry distillation chamber through the feeding port for processing, so that the pushing screw shaft pushes the raw materials to be discharged from the discharge bin.

[0008] Preferably, the top cover plate is sealed to the clean room shell via a flange and a sealing ring.

[0009] By adopting the above technical solution, when using the device, the top cover plate is sealed and connected to the purification chamber through the flange and the sealing ring, and the gas is introduced into the purification chamber through the exhaust port and the air inlet pipe for purification.

[0010] Preferably, one end of the temperature sensor is connected to the thermometer, and the end of the temperature sensor connected to the thermometer passes through the top cover.

[0011] By adopting the above technical solution, when the device is used, the thermometer at one end of the temperature sensor is extended into the purification room for detection.

[0012] Preferably, one end of the temperature sensor connected to the thermometer is flush with the air duct, and the liquid level gauge is located on the outer surface of the purification chamber.

[0013] By adopting the above technical solution, when the device is used, the purified gas is conveniently introduced into the collection chamber for collection through the air guide pipe, and the impurities adsorbed by the solvent are discharged from the purification chamber through the sewage bottom valve.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the purification device for cooling and removing impurities for tobacco dry distillation:

[0017] 1. This device treats the high-temperature gas generated by dry distillation before it enters the collection chamber, removes dust and tar droplets by adsorption, and reduces the temperature of the high-temperature gas, thereby ensuring the purity of the collected material, reducing the working pressure of the cooling circulation system in the collection chamber, thereby reducing energy consumption, and improving the physical and chemical indicators and product stability of the dry distillation product.

[0018] 2. This device uses gravity to settle fine dust and tar-like substances in the high-temperature gas generated in the retorting chamber. By adding a certain solvent to the device, the proportion and type of solvent added can be selected based on the conditions for selective adsorption of the high-temperature gas generated by the retorting process. For example, since dust and tar droplets are insoluble in water, and water has a relatively large specific heat capacity, adding water as a solvent not only prevents fires but also easily adsorbs dust and tar droplets through its surface tension, making it a safe and affordable cooling solvent.

[0019] 3. The solvent level added to this device is selectively submerged or submerged at the end of the inlet pipe, allowing for selective adsorption of the high-temperature gases generated by dry distillation. This allows for adsorption of the gases entering the collection chamber, further improving the purity and concentration of the desired products and reducing the difficulty of subsequent separation and purification. For example, water, propylene glycol, glycerin, and vegetable oil can selectively adsorb components in the high-temperature gases due to their different polarity. The addition of zeolite can further absorb hazardous components such as tobacco nitrosamines and benzene series. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] An installation opening 3 is provided on the surface of the top cover plate 2, and an air inlet pipe 4 is fixedly connected to the inner wall of the installation opening 3. One end of the temperature sensor 5 is connected to the thermometer, and the end of the temperature sensor 5 connected to the thermometer passes through the top cover plate 2. The end of the temperature sensor 5 connected to the thermometer is flush with the air guide pipe 8. The liquid level gauge 11 is located on the outer surface of the purification chamber 1. During operation, gas is introduced into the purification chamber 1 through the air inlet pipe 4, and the high-temperature gas is used to settle fine dust and tar-like substances in the purification chamber 1 through the action of gravity. By adding a certain solvent to the purification chamber 1, the temperature of the high-temperature gas can be reduced at the same time. Finally, the adsorbed impurities are discharged and cleaned through the sewage bottom valve 6, and then the water pipe in the collection chamber 7 cools the gas again through the movement of water flow.

[0027] A temperature sensor 5 is fixedly installed on the lower surface of the top cover plate 2, a bottom valve 6 is installed at the lower end of the purification chamber 1, two collecting chambers 7 are arranged on the side of the purification chamber 1, a feed port 9 is installed on the upper surface of the collecting chamber 7, a discharge port 10 is arranged on the lower surface of the collecting chamber 7, and two openings are arranged on the outer surface of the collecting chamber 7, and the two openings of the collecting chamber 7 are staggered up and down. The two openings of the collecting chamber 7 are respectively connected to the water inlet pipe and the water outlet pipe. Based on the principle that Bernoulli gas flows from a narrow channel into a larger channel, the gas flow rate decreases, so that After the high-temperature gas enters the purification chamber 1 through the air inlet pipe 4, the gas flow rate drops sharply due to the sudden increase in the gas channel. At this time, due to the effect of gravity, the dust particles and tar droplets will fall, while other gas molecules will rise, which plays a role in purification and impurity removal. Adding one or more mixed solvents such as water, propylene glycol, glycerol, and vegetable oil into the purification chamber 1 can adsorb the descending dust particles and tar droplets, and by adding the solvent and reducing the gas flow rate, the temperature of the high-temperature gas is reduced, which plays a certain cooling role.

[0028] A liquid level gauge 11 is connected to the surface of the collecting chamber 7, and a vacuum pump pipe 12 is installed on the upper surface of the collecting chamber 7. The two collecting chambers 7 are connected by a pipeline, and an air guide pipe 8 is installed between the collecting chamber 7 on one side and the purification chamber 1. A water pipe is fixedly installed on the inner wall of the cavity of the collecting chamber 7, and the two ends of the water pipe on the inner wall of the collecting chamber 7 are respectively connected to the water inlet pipe and the water outlet pipe. This device is not only easy to operate and has a simple structure, but also adsorbs and removes dust and tar oil droplets and reduces the temperature of the high-temperature gas before the high-temperature gas enters the collecting chamber 7, thereby improving the purity of the collected material in the collecting chamber 7, and also reducing the working pressure of the cooling circulation system such as the water pipe in the collecting chamber 7, thereby reducing energy consumption. This device can be used in series or parallel to further enhance its purification and impurity removal, selective adsorption and cooling effects, and this device can also be a constant type, and by using it in series or parallel, it can also achieve its purification and impurity removal, selective adsorption and cooling effects, and has good practical significance.

[0029] Working principle: When using the cooling and impurity removal purification device for dry distillation, a cooling and impurity removal purification structure is designed between the dry distillation chamber and the collection chamber 7, so that the air inlet pipe 4 introduces the gas into the purification chamber 1, and the high-temperature gas entering the collection chamber 7 is purified by adding a solvent into the purification chamber 1. The adsorbed impurities are discharged through the sewage bottom valve 6, thereby improving the purity of the collected liquid in the collection chamber 7. At the same time, the temperature of the high-temperature gas entering the collection chamber 7 is further reduced, and the working pressure of the circulating cooling system such as the water pipe in the collection chamber 7 is reduced, thereby reducing energy consumption and increasing overall practicality.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
