Abstract
Description
Technical Field
[0001] The present application relates to the technical field of smoking evaluation equipment, and in particular to an anti-corrosion experimental table with a built-in smoking evaluation function for use in laboratories. Background Art
[0002] Whether it is cigarettes, cigars or new tobacco, before these tobacco products are officially put into production, it is necessary to conduct sensory evaluation of the whole process of tobacco products such as tobacco raw materials, flavors (except cigars), cigarettes, and finished products, and strictly control the quality of the taste and flavor. Professional cigarette evaluation should be implemented in accordance with the national standard GB 5606.4-2005 "Cigarette Part 4 Sensory Technical Requirements", and generally more than 7 people are organized to conduct experiments in the evaluation room. As tobacco is constantly lit and evaluated, it turns into smoke and diffuses in the room. The environmental state of the evaluation personnel gradually deteriorates. At the same time, the concentration of carbon dioxide and other indoors gradually increases. The hypoxic state is not conducive to the evaluation personnel to make clear judgments, especially when they need to evaluate a variety of tobacco products. Although more and more evaluation rooms have been equipped with exhaust systems in recent years, only a simple exhaust system is set up without an effective air supply system. From the theoretical perspective of air volume balance, this determines that the exhaust system cannot quickly and effectively remove harmful smoke in the room, and the evaluation personnel will still be in a harmful environment for a long time. In addition, the exhaust system of the traditional smoking evaluation room needs to be ventilated more than 20 times per hour, which is a very large ventilation volume. This will greatly increase the air conditioning energy consumption of the room in winter and summer, which is not in line with the social trend of energy conservation and emission reduction. In addition, smoking evaluation is also required in independent formula experiments, smoking evaluation ability training, competitive product analysis and other work, and the number of people in this type of work is often uncertain. Using a professional smoking evaluation room with few people will cause energy waste, and the ventilation effect of the smoking evaluation room will not meet the standard when there are many people. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides an anti-corrosion test bench with a built-in smoking evaluation function for laboratory use, which can improve the air quality in the smoking evaluation room and can quickly collect smoke in a small range, which not only helps to protect the health of smoking evaluation personnel, but also enables smoking evaluation personnel to complete their work in a good state. The rapid response method of exhausting and treating smoke immediately can reduce the ventilation times in the smoking evaluation room and reduce the energy consumption of air conditioning. As long as the room is reserved for the unit-type sensory smoking evaluation test bench, it can also be quickly added and moved, so that the convenience of the experiment and the utilization rate of resources are further improved.
[0004] The technical solution provided by the utility model is as follows:
[0005] The invention discloses an anti-corrosion experiment table with a built-in smoking evaluation function for use in a laboratory, comprising a cabinet, a desktop panel, a control cabinet, a smoke exhaust system arranged in the cabinet, and a fresh air replenishment system for always keeping the indoor air clean.

[0011] Preferably, the air outlet end of the circulation pipe and the air outlet end of the fresh air replenishment system share a bag air duct.
[0012] Preferably, the bag air duct is provided with a plurality of nozzles.

[0014] The present application has the following advantages over the prior art:
[0015] When the laboratory of the present application uses an anti-corrosion test bench with a built-in smoking evaluation function, the setting of a smoke exhaust system and a fresh air supplement system can ensure that cigarette smokers can conduct experiments in a clean indoor environment. At the same time, the harmful smoke generated by the evaluation can be centrally collected and processed through the smoke exhaust system and then discharged to the outdoors or circulated to the indoors; secondly, the test bench of the present application has strict requirements on the rate of gas flowing through each unit in the smoke exhaust system. The smoke flow rate in the smoke intake unit and the smoke exhaust unit must be guaranteed to be 12~15m / s, and the cross-sectional wind speed of the smoke filtration unit must be controlled at 1.5~2m / s. The high wind speed requirement of the former can ensure that the smoke is quickly absorbed and discharged, and the low wind speed flow requirement of the latter can ensure that the smoke is fully absorbed and decomposed in the filtration unit (the basic principle is that The lower the cross-sectional wind speed of the filter unit, the higher the efficiency of harmful substance treatment); in addition, the spatial position and airflow organization of the air outlet of the fresh air replenishment system and the air intake unit of the smoke exhaust system in the room test bench of the present application have also been carefully designed. It can be foreseen that the gas sent out from the air outlet of the fresh air replenishment system can form a natural annular airflow, wrapping the harmful smoke next to the smoking station, and with the support of the rapid exhaust system (negative pressure is formed near the air intake unit of the smoke exhaust system at this time), the air cleaned by the test bench carries the harmful smoke from top to bottom into the suction hood; it should also be noted that starting the internal circulation mode is more conducive to energy saving, while starting the external circulation mode can replenish fresh air, increase the indoor oxygen content, and reduce the carbon dioxide concentration, so that the smoking assessors can make subjective evaluations in a more sober state.

[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] like Figure 1 , 2 As shown, an embodiment of the utility model provides an anti-corrosion experiment table with a built-in smoking evaluation function for use in a laboratory, comprising a cabinet 1, a desktop panel 7, a control cabinet 2, a smoke exhaust system 3 arranged in the cabinet 1, and a fresh air replenishment system 4 for always keeping the indoor air clean. The desktop panel 7 and the control cabinet 2 are respectively arranged on the outside of the cabinet 1, and the air outlet of the fresh air replenishment system 4 and the smoke inlet of the smoke exhaust system 3 are located on the same side of the cabinet 1. The desktop panel 7 is located below the smoke inlet of the smoke exhaust system 3 for the convenience of smokers. A control unit for respectively controlling the smoke exhaust system 3 and the fresh air replenishment system 4 is provided in the control cabinet 2.
[0023] In this embodiment, a total heat exchanger 5 is provided between the smoke exhaust system 3 and the fresh air supply system 4, and the smoke exhaust system 3 and the fresh air supply system 4 share a total heat exchanger 5, and the total heat exchanger 5 is arranged on the gas pipeline for mutual transportation of indoor air and outdoor air.
[0024] In this embodiment, the smoke exhaust system 3 includes an air intake unit, a filter unit and an exhaust unit. The filter unit is arranged on the gas channel between the air intake unit and the exhaust unit. The air intake units are connected to the smoke exhaled by the smoker. The exhaust unit is arranged at the gas outlet of the total heat exchanger 5, and the total heat exchanger 5 is arranged at the gas outlet of the filter unit. According to the gas flow direction, the filter unit includes an electronic dust collection chamber 301, a laminar filter 302, activated carbon 303 and an oxygen ion generator 304 in sequence. The electronic dust collection chamber 301, the laminar filter 302, the activated carbon 303 and the oxygen ion generator 304 are used to remove particulate matter and VCO in the smoke. According to the gas flow direction, the air intake unit includes an air suction hood 305, an air intake pipe 306, and a reducer 307 in sequence. According to the gas flow direction, the exhaust unit includes a reducer pipe 308, an exhaust pipe connected to the outdoor air and a circulation pipe 309 connected to the indoor air. The exhaust pipe includes an exhaust pipe section 1 310 arranged at the gas inlet of the total heat exchanger 5 and an exhaust pipe section 2 311 arranged at the gas outlet of the total heat exchanger 5; an air valve 1 312 and an exhaust fan 313 are respectively provided on the exhaust pipe section 1 310, and an air valve 2 314 is provided on the circulation pipe 309.
[0025] In this embodiment, the air outlet end of the circulation pipe 309 and the air outlet end of the fresh air replenishment system 4 share a bag air duct 6. The bag air duct 6 is provided with a plurality of nozzles 61, and the inner angle between the nozzles 61 arranged on both sides is 120°~150° (the specific angle can be determined according to demand). The nozzles 61 on both sides are arranged at this angle, and the air supply can form a natural annular airflow, wrapping the harmful smoke around the smoking station, and with the support of the rapid exhaust system, a negative pressure is formed near the suction hood 305, and the cleaned air enters the suction hood 305 from top to bottom with the harmful smoke. The bag air duct 6 is provided with a plurality of nozzles 61, and the fresh air or the filtered air can be evenly delivered to the vicinity of the smoking station.
[0026] In this embodiment, the fresh air replenishment system 4 includes a fresh air inlet pipe 401, a primary filter 402, a medium filter 403 and a fresh air exhaust pipe. The fresh air exhaust pipe includes a fresh air exhaust pipe section 1 404 located at the gas inlet of the total heat exchanger 5 and a fresh air exhaust pipe section 2 405 located at the gas outlet of the total heat exchanger 5. The fresh air exhaust pipe section 1 404 is provided with a fresh air fan 406, and the fresh air exhaust pipe section 2 405 is provided with a fresh air valve 407.
[0027] In this embodiment, the operation mode of the smoke exhaust system 3 is as follows: the smoke exhaled by the smoker enters the air inlet pipe 306 through the suction hood 305, and then enters the smoke filtration treatment section after being intercepted and reduced in speed by the reducer 307. After passing through the electronic dust collection chamber 301, the laminar filter 302, the activated carbon 303, and the negative oxygen ion generator 304 to remove the particulate matter and VCO in the smoke, the smoke is sucked into the exhaust pipe section 1 310 from the reducer 2 308 by the exhaust fan. If the treated smoke is to be discharged outdoors, the clean smoke is discharged through the exhaust pipe section 1 310-1, air valve 1 312 enters the exhaust cavity of the total heat exchanger 5 and then enters the exhaust pipe section 2 311, and is finally discharged to the outside through the exhaust hole of the exhaust pipe section 2 311; if the treated smoke needs to be circulated to the room, the clean smoke enters the bag air duct 6 at the air supply end through the circulation pipe 309 and air valve 2 314, and is evenly delivered to the area where the smoker is located by the small hole nozzle 61 arranged on the bag air duct 6. In the circulation mode, the air valve 1 312 and the fresh air valve 407 are closed, and the fresh air supply system 4 stops working.
[0028] In this embodiment, the operation mode of the fresh air replenishment system 4 is as follows: outdoor fresh air is sucked into the fresh air inlet pipe 401 through the fresh air port, and after being processed by the primary filter 402 and the medium efficiency filter 403, the fresh air is transported to the fresh air duct exhaust section 1 404 by the fresh air fan 406, and then enters the exhaust cavity of the total heat exchanger 5 and enters the fresh air exhaust pipe section 2 405, and is transported to the bag air duct 6 at the air supply end after being adjusted by the fresh air valve 407, and is evenly delivered to the area where the smoker is located by the small hole nozzle 61 arranged on the bag air duct 6.
[0029] In this embodiment, when the smoke exhaust system 3 and the fresh air supply system 4 operate together, it is in the internal circulation mode, and when the smoke exhaust system 3 circulates to the room alone through the circulation pipe 309, it is in the internal circulation mode. Regardless of the internal circulation mode or the external circulation mode, both can ensure that tobacco smoking testers can conduct experiments in a clean environment (both can achieve the following functions: 1) Indoor air volume balance, with both delivery and exhaust or delivery and return; 2) Harmful smoke is exhausted and treated immediately; 3) Effective airflow organization can prevent the spread of smoke; 4) Reasonable wind speed design improves the absorption and treatment effect of smoke). The difference is that the internal circulation mode is more energy-saving because only one fan is turned on and no outdoor fresh air is introduced; while the external circulation mode can supply fresh air, increase the indoor oxygen content, and reduce the carbon dioxide concentration, so that the indoor environment is both clean and comfortable. The user can switch the control mode according to needs.
[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
