[0020] The specific embodiments of the patent are described in detail below in combination with the drawings to better understand the technical content of the patent, but the patent should not be limited to this.

[0021] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present patent will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] As shown in the figure, the present patent provides a drum solid-liquid separator waste gas collecting device, which comprises a drum solid-liquid separator, airtight doors and a waste gas collecting device.

[0023] In the embodiment, the drum solid-liquid separator is composed of a drum, a feeding port, a discharging port and a frame. The drum is a hollow cylindrical structure, and a plurality of through holes are uniformly distributed on the outer surface. The drum is supported on the frame through bearings at both ends, and the frame is fixedly connected with the ground to ensure the stability of the overall structure. The drum and the frame together form an airtight space, which effectively prevents the leakage of waste gas. The airtight space is connected with the waste gas collecting device through an airflow guide pipe. A check valve is arranged in the airflow guide pipe. The check valve prevents backflow of waste gas and ensures one-way flow of waste gas during collection and treatment.

[0024] In the embodiment, the feeding port and the discharging port are respectively provided with airtight doors. The airtight door comprises a door frame, a door plate and a sealing ring. The door frame is installed outside the feeding port and the discharging port of the drum solid-liquid separator and is fixedly connected with the drum shell. The door plate adopts a double-layer steel plate structure and is filled with high-density soundproof and heat-insulating material inside. This not only improves the sealing performance, but also significantly reduces the operating noise. The door plate is hinged to the door frame through a hinge to facilitate flexible opening and closing. The sealing ring is fixed to the inner side edge of the door frame and tightly fits the edge of the feeding port and the discharging port, thereby forming a reliable airtight connection to prevent leakage of waste gas.

[0025] In the embodiment, the waste gas collecting device is composed of a waste gas storage cavity, a filter assembly, a purification module and an exhaust fan. The waste gas storage cavity is located on one side of the drum solid-liquid separator and has a rectangular box structure. It is communicated with the airtight space outside the drum through an airflow guide pipe and is used for temporarily storing waste gas. The filter assembly is arranged at the top outlet of the waste gas storage cavity and is fixed by a detachable slot structure for easy maintenance and replacement. The purification module comprises a primary filter screen, an activated carbon adsorption layer and a high-efficiency particle filter membrane, which are arranged in sequence and cooperate to realize multi-stage purification treatment of waste gas. The exhaust fan is installed at the end outlet of the filter assembly and is connected with an external exhaust pipeline through a flexible pipeline for discharging the treated clean gas to the outside.

[0026] In this embodiment, the filter assembly is composed of a primary filter screen, an activated carbon adsorption layer, and a high-efficiency particulate filter membrane, which are arranged in layers to form a layered purification structure. The primary filter screen is used to intercept large particulate matter in the exhaust gas, reducing the load on the subsequent filter layers. The activated carbon adsorption layer is mainly used to adsorb volatile organic compounds (VOCs) in the exhaust gas, significantly reducing the odor concentration of the exhaust gas. The high-efficiency particulate filter membrane is used to capture fine particulate matter, further purifying the gas. The filter assembly is fixed at the top outlet of the exhaust gas storage chamber through a slot structure. The slot design facilitates the quick disassembly and replacement of the filter layer, improving the maintenance efficiency of the equipment. This design is suitable for scenarios where the composition of the exhaust gas is complex, ensuring that the discharged gas meets environmental standards.

[0027] In this embodiment, a slanted gas-liquid separation plate is added inside the exhaust gas storage chamber to further optimize the exhaust gas treatment process. The gas-liquid separation plate is installed at an angle and made of corrosion-resistant metal plate. The upper surface is provided with several guide grooves. When the exhaust gas passes through the storage chamber, the gas-liquid separation plate can effectively separate the liquid components in the exhaust gas. The liquid flows along the guide grooves to the bottom. The bottom of the exhaust gas storage chamber is connected to a liquid discharge pipe, which communicates with the liquid discharge port of the drum solid-liquid separator, thereby realizing the centralized recovery of separated liquid. This improvement is particularly suitable for handling exhaust gas with high humidity, effectively preventing the influence of water vapor on the filter assembly and exhaust fan, and prolonging the service life of the equipment.

[0028] Working principle

[0029] The core function of the drum solid-liquid separator exhaust gas collection device is to collect and purify the exhaust gas generated during the operation of the drum solid-liquid separator through airtight structure and multi-stage purification treatment, to meet the requirements of environmental protection and safety in industrial production. The working principle of the patent is described in detail below.

[0030] The main function of the drum solid-liquid separator is to separate solids and liquids in the material. Its core component is a hollow cylindrical drum.

[0031] Feeding and separation: The material enters the drum from the feeding port. When the drum rotates, the liquid and gas are evenly distributed through the perforations on the drum surface, while the solids are retained in the drum and eventually discharged from the discharge port.

[0032] Exhaust gas generation: Due to the characteristics of the material (such as humidity, volatile organic content, etc.) and the friction and agitation during the separation process, a certain amount of exhaust gas is generated in the drum. These exhaust gases may contain volatile organic compounds (VOCs), fine particulate matter, water vapor, and other pollutants, which need to be collected and treated in a timely manner.

[0033] The drum solid-liquid separator and the frame form a sealed space. The exhaust gas generated in the drum is introduced into the treatment through the exhaust gas collection device. The working principle is as follows:

[0034] The role of the airtight structure

[0035] Both the inlet and outlet of the drum solid-liquid separator are equipped with airtight doors made of double-layer steel and high-density soundproofing and heat-insulating materials, which are tightly attached to the equipment shell through a sealing ring to form an airtight connection.

[0036] When waste gas is generated, the airtight door can effectively prevent waste gas leakage.

[0037] The role of airflow guide and check valve

[0038] The waste gas in the airtight space enters the waste gas collection device through the airflow guide pipe. The check valve inside the airflow guide pipe ensures one-way flow of waste gas, preventing external air from flowing into the drum solid-liquid separator, and maintaining the airtightness and stability of the waste gas treatment system.

[0039] After the waste gas enters the waste gas collection device through the airflow guide pipe, it goes through the steps of waste gas storage, gas-liquid separation, filtration and purification, and discharge in sequence. The specific working principle is as follows:

[0040] (1) The role of waste gas storage chamber

[0041] Waste gas first enters the waste gas storage chamber, which is a rectangular box structure, used to temporarily store waste gas and balance gas pressure, avoiding the impact of instantaneous high-flow waste gas on subsequent processing modules.

[0042] Inside the storage chamber, the flow rate of waste gas is reduced, and part of the particulate matter naturally settles to the bottom due to gravity, thereby reducing the burden on the subsequent filtration system.

[0043] (2) Gas-liquid separation process

[0044] The waste gas storage chamber is equipped with an inclined gas-liquid separation plate. When waste gas passes through the separation plate, the guide grooves on the surface of the plate will guide gas-liquid separation:

[0045] After being intercepted by the separation plate, water vapor and other liquid components flow along the guide grooves to the bottom of the storage chamber and are discharged through the drain pipe to the drum drain port. The liquid is eventually collected and recycled together with the waste liquid generated during the drum separation process.

[0046] The separated waste gas then enters the filtration system for further processing.

[0047] (3) Multi-stage filtration and purification

[0048] After gas-liquid separation, the waste gas is subjected to multi-stage purification treatment through the filtration assembly, which specifically includes:

[0049] Primary filter screen: filters large particles in waste gas, serving as a preliminary purification function;

[0050] Activated carbon adsorption layer: adsorbs volatile organic compounds (VOC) in waste gas, reduces odor and harmful substance concentration in gas;

[0051] High-efficiency particle filtration membrane: captures fine particulate matter in waste gas, further purifies gas, and ensures that emissions meet environmental protection standards.

[0052] The filter assembly is fixed with a slot structure, which is convenient for operators to replace the filter layer regularly.

[0053] (4) The role of the exhaust fan

[0054] The clean gas after multi-stage filtration and purification is extracted by the exhaust fan, discharged to the atmosphere through flexible pipeline and external exhaust pipeline.

[0055] The exhaust fan can adjust the waste gas flow to ensure the stability of waste gas collection and purification.

[0056] The working principle of the device is to achieve comprehensive control of waste gas through closed design and multi-stage purification treatment:

[0057] Environmental protection: the purified waste gas completely meets the emission standards, reducing the pollution of industrial production to the environment;

[0058] Safety: The design of closed system and check valve effectively prevents waste gas leakage, reducing the risk of leakage of explosive or harmful gas.

[0059] Through the above structural design, the embodiment can realize efficient collection and treatment of waste gas, and significantly improve the working environment.

[0060] The above specific embodiment is a typical embodiment of the patent, but the patent is not limited to this, and reasonable changes can be made to its structure, material and pulse ash removal device logic without deviating from the core technical idea of the patent. All improvements based on this fall within the scope of protection of the patent.

Without departing from the spirit and essence of the patent, various changes and modifications can be made to the specific embodiments of the patent, and these changes and modifications all belong to the scope covered by the patent.
