A smart device for collecting exhaust steam generated in brewing processes

Abstract

This utility model discloses an intelligent collection device for waste steam generated in brewing processes, relating to the field of waste steam collection and treatment equipment. It includes a waste steam collection hood, a waste steam guiding device, and an intelligent control system. The utility model features an arc-shaped gas collection hood with an arc-shaped top and a rectangular opening. Air curtain machines are installed around the hood, forming a fully enclosed air barrier against the rising waste steam through the high-speed airflow of the air curtain machines. This isolates different temperature and humidity zones, blocks lateral airflow interference, and directly pushes the waste steam towards the collection hood for complete collection, preventing overflow during the rising process and avoiding excessive instantaneous flow. The intelligent control system incorporates a gas flow sensor inside the collection hood. By monitoring the flow rate of the exhaust gases inside and outside the hood in real time, it links the on / off state, air volume, and running time of the air curtain machines, as well as the air volume of the exhaust fans, achieving intelligent control of the waste steam collection device. This is beneficial for energy conservation and emission reduction in brewing production processes.

Description

Technical Field

[0001] This utility model relates to the field of waste steam collection and treatment equipment, specifically an intelligent collection device for waste steam generated in brewing processes. Background Technology

[0002] Food processing plants (such as those processing alcoholic beverages, food products, and condiments) generate a large amount of waste gas and heat during the production process. For example, in the liquor brewing process, the still (grain still) generates a large amount of hot waste gas during the distillation (distillation of grains) and turning process. If this hot waste gas is not collected and treated, it will pollute the entire operating environment. Especially when the amount of hot gas is large and the ambient temperature is low, white smoke will spread, affecting the operator's vision and normal operation.

[0003] The current method for treating the aforementioned exhaust steam is to install a collection hood above the exhaust steam source. The hot steam rises to the collection hood for collection, and then the hot steam is discharged through an exhaust fan and exhaust pipe, or discharged into a hot exhaust steam treatment device for further treatment.

[0004] Practice has proven that this approach has significant drawbacks. Because the exhaust steam source equipment or related equipment consists of moving parts (such as during a tipping process), the collection hood cannot collect the exhaust steam nearby (it is usually positioned very high). Furthermore, due to space constraints, the collection hood cannot be made very large, causing hot steam to diffuse outside the hood during its ascent, reducing the collection efficiency. In particular, in cases of excessively high instantaneous flow rates, the collection hood may fail to effectively collect the hot steam, resulting in a large amount of hot steam escaping into the surrounding environment. This not only pollutes the production environment but also directly affects worker operations and hinders clean production in the workshop. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides an intelligent collection device for waste steam generated during brewing processes. By utilizing an air curtain machine and an intelligent control system, it achieves efficient and intelligent collection of waste steam.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A smart collection device for waste steam generated in the brewing industry includes a waste steam collection hood, a waste steam guiding device, and a smart control system. The waste steam collection hood adopts an arc-shaped structure with an arc-shaped top and a rectangular opening. Height-adjustable baffles are installed around the opening, and angle-adjustable guide plates are installed at the bottom of the baffles. An external exhaust port is located at the top of the waste steam collection hood, connecting to an external exhaust fan and a hot waste steam treatment device. The waste steam guiding device is an air curtain machine, with one air curtain machine installed around the opening of the waste steam collection hood to form a waste steam guiding device. A gas flow sensor is installed near the external exhaust port on the waste steam collection hood. The smart control system includes a main control module and a signal... The system comprises a gas flow sensor, a signal acquisition module, a signal processing module, a display module, a communication module, and a host computer. The gas flow sensor, signal acquisition module, and signal processing module are sequentially connected and then connected to the signal input terminal of the main control module. The signal output terminal of the main control module is connected to the switch, air volume adjustment button, running time button of each air curtain machine, the flow control valve of the exhaust fan, and the display module, respectively. The main control module is loaded with a control program that collects flow data from the gas flow sensor, processes it, and then controls the switch, air volume adjustment, running time adjustment of each air curtain machine, as well as the air volume adjustment of the exhaust fan. The main control module is connected to the host computer via the communication module to achieve remote monitoring.

[0007] The main control module uses a PLC controller or a microprocessor / microcontroller.

[0008] An external control cabinet is set up on site, integrating the main control module, signal acquisition module, signal processing module and display module. Data can be viewed and controlled through the display module connected to the display screen.

[0009] The baffle consists of a fixed plate and an adjusting plate. The fixed plate is fixedly installed around the opening of the exhaust steam collection hood. Several adjusting holes are symmetrically arranged on both sides of the fixed plate. The adjusting plate is connected to the fixed plate by screws passing through the adjusting holes. The height adjustment range is 5-10cm.

[0010] The adjustment range of the horizontal tilt angle of the guide plate is set between 45° and 60°, and the bottom of the baffle is provided with an angle adjustment slot for connecting the guide plate.

[0011] The beneficial effects of this utility model are as follows: 1) An arc-shaped gas collection hood with an arc-shaped top and a rectangular opening was designed, and air curtain machines were installed around the gas collection hood. The high-speed airflow of the air curtain machines around the hood forms a fully enclosed air barrier for the rising exhaust steam, isolating different temperature and humidity areas, blocking the interference of lateral airflow, and pushing the exhaust steam flow directly into the gas collection hood for complete collection, thus avoiding the overflow of exhaust steam during the rising process and the occurrence of excessive instantaneous flow. 2) An adjustable height baffle and an adjustable angle guide plate are installed at the bottom of the gas collection hood opening to allow the rising exhaust steam to enter the gas collection hood for collection more quickly. The adjustment can be made according to the specific exhaust steam source equipment without adjusting the position and shape of the gas collection hood. This provides high operational flexibility and greatly improves the exhaust steam collection efficiency. 3) An intelligent control system was designed, with a gas flow sensor installed inside the gas collection hood. By monitoring the flow rate of the exhaust gas inside and outside the gas collection hood in real time, the system can link the on / off state, air volume, running time of the air curtain machine, and the air volume of the exhaust fan to achieve intelligent control of the exhaust steam collection device. Tests have shown that this reduces heat loss by 80-90%, which is beneficial to energy conservation and emission reduction in the brewing process. 4) It is especially suitable for situations where the exhaust steam source equipment has a complex shape and needs to be moved. It is not limited by space and does not require the design of a complicated movable gas collection hood. It only needs to be slightly adjusted according to the actual situation. It has a wide range of applications, collects exhaust steam thoroughly, greatly improves the environment of the production workshop, meets the clean production requirements of the workshop, and provides a better environment for workers to operate.

The waste steam collection hood 1 adopts an arc-shaped gas collection hood structure with an arc-shaped top and a rectangular opening. Height-adjustable baffles 11 are installed around the opening, and angle-adjustable guide plates 12 are installed at the bottom of the baffles 11. An external exhaust port 3 is provided at the top of the waste steam collection hood 1, which is connected to an external exhaust fan and a hot waste steam treatment device. The waste steam guiding device 2 is an air curtain machine, with one air curtain machine installed around the opening of the waste steam collection hood 1 to form the waste steam guiding device 2. A gas flow sensor 14 is installed near the external exhaust port 13 on the waste steam collection hood 1. The intelligent control system includes a main control module 31, a signal acquisition module 32, and a signal processing module 33. The system comprises a processing module 33, a display module 34, a communication module 35, and a host computer 36. The gas flow sensor 14, signal acquisition module 32, and signal processing module 33 are sequentially connected and then connected to the signal input terminal of the main control module 31. The signal output terminal of the main control module 31 is connected to the switch 21, air volume adjustment button 22, running time button 23 of each air curtain machine, the flow regulation valve of the exhaust fan, and the display module 34, respectively. The main control module 31 collects the flow data from the gas flow sensor 14, processes it, and then controls and regulates the execution components 37, specifically including the switch, air volume adjustment, running time adjustment of each air curtain machine, and air volume adjustment of the exhaust fan. The main control module 31 is connected to the host computer 36 through the communication module 35 to realize remote monitoring.

[0014] In this preferred embodiment, the main control module 31 is a PLC controller or a microprocessor / microcontroller.

[0015] As a preferred embodiment, an external control cabinet is set up on site, and the main control module 31, signal acquisition module 32, signal processing module 33 and display module 34 are integrated in the control cabinet. Data can be viewed and controlled by connecting the display module 34 through the display screen.

[0016] In a preferred embodiment, the baffle 11 is composed of a fixed plate 11 and an adjusting plate 112. The fixed plate 111 is fixedly disposed around the opening of the exhaust steam collection hood 1. Several adjusting holes are symmetrically arranged on both sides of the fixed plate 111. The adjusting plate 112 is connected to the fixed plate 111 by screws passing through the adjusting holes. The height adjustment range is 5-10cm.

[0017] In a preferred embodiment, the angle adjustment range of the guide plate 12 with the horizontal direction is set between 45° and 60°, and the bottom of the baffle 11 is provided with an angle adjustment slot for connecting the guide plate 12.

[0018] It should be noted that in this embodiment, the specific integrated circuits of the main control module 31, signal acquisition module 32, signal processing module 33, and display module 34 involved in the intelligent control system, as well as the control program loaded on the main control module 31, the communication module 35, and the remote monitoring implemented by the host computer 36, can all be expanded to include remote control or mobile APP control as needed in the future.

Related technicians can design and select applications according to actual needs and edit corresponding control programs, such as... Figure 5 The diagram shows the control system circuit used in this embodiment. This invention aims only to apply the intelligent control system to the waste steam collection device to achieve better intelligent linkage effects, rather than to improve or upgrade the specific circuitry and functions of the intelligent control system. Therefore, there are no issues of insufficient disclosure or unclear solutions.

[0019] In practical use, this invention adjusts the height of the baffle 11 and the inclination angle of the guide plate 12 according to the conditions of the steamer equipment 4 on site. When the steamer is about to generate exhaust steam during the tilting and unloading process, the control system (controlled by the control cabinet or remotely monitored) turns on the switches of the four air curtain machines in advance. The air curtain machines start working, and when the gas flow sensor 14 detects no gas, the exhaust steam collection is complete, and the switches of the four air curtain machines are turned off. During the exhaust steam collection process, the air volume and running time of the air curtain machines and the air volume of the exhaust fan are adjusted according to the flow data of the gas flow sensor 14. With a moderate exhaust fan air volume, a good exhaust steam collection effect is achieved, thereby meeting the requirements of energy conservation and emission reduction.
