Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, and more specifically to a VOC waste gas treatment device for environmental protection equipment. Background Art

[0002] VOC stands for volatile organic compounds. In the general sense, VOC refers to volatile organic compounds. VOC in industrial waste gas is an important source of air pollutants. The waste gas needs to be separated and treated before it can be discharged.

[0003] Existing catalytic VOC waste gas treatment devices use dispersion pipes to spray waste gas into reaction equipment and liquid catalysts for spray purification. When spraying, high-temperature waste gas carries solid impurities directly into the dispersion pipes. Solid impurities can cause pipes, especially nozzles, to be blocked, affecting gas passage efficiency. In view of this, we propose a VOC waste gas treatment device for environmental protection equipment. Utility Model Content

DETAILED DESCRIPTION

[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] This embodiment provides a VOC waste gas treatment device for environmental protection equipment, referring to Figure 1, including a box body 1, the box body 1 is manufactured by a welding frame and a rear-laid plate to form a rectangular box structure that is through from left to right, with a port on each side at both ends, wherein a continuous air inlet section 2, a relay section 8 and an air outlet section 9 are arranged inside the box body 1, and the air inlet section 2, the relay section 8 and the air outlet section 9 are formed by the solid-gas separation frame 4 and the cooling component 5 inside the box body 1 to separate the continuous space of the box body 1. Specifically, a solid-gas separation frame 4 is arranged at the junction of the air inlet section 2 and the relay section 8, so that the exhaust gas entering the relay section 8 through the air inlet section 2 is dust-removed by the solid-gas separation frame 4, and the solid-gas separation frame 4 can separate and intercept solid impurities in the exhaust gas to obtain cleaner exhaust gas. Afterwards, a cooling component 5 is arranged at the junction of the relay section 8 and the air outlet section 9, and the clean exhaust gas passes through the cooling component 5 through the relay section 8 and enters the air outlet section 9. The cooling component 5 adopts a water-cooled pipe or an air-cooled pipe group, and is matched with a reciprocatingly coiled pipe to obtain a larger surface area, which can be In order to cool down the exhaust gas passing through and protect the subsequent blower 7 and catalytic impurity removal system, wherein the blower 7 is arranged in the air outlet section 9, and works to push the exhaust gas in the box body 1 to the right and discharge it, so that the box body 1 is in a negative pressure state, and the exhaust gas is continuously sucked into the box body 1 from the left opening. During use, when the solid-gas separation rack 4 is blocked and the air flow rate difference is caused, an air guide duct 6 is installed between the relay section 8 and the air outlet section 9. The air guide duct 6 is opened to pass through the cooling component 5 to connect the relay section 8 and the air outlet section 9. At this time, the blower 7 is connected to the atmosphere and reversed for backblowing. It should be noted that the blower 7 adopts a blower that can be pumped forward and backward, and the high-speed airflow can be passed through the cooling component 5 through the air guide duct 6 to backblow and clear the solid-gas separation rack 4. The air guide duct 6 passes through the cooling component 5 to avoid the speed reduction when the airflow directly passes through the cooling component 5, which can effectively improve the backblowing cleaning efficiency of the solid-gas separation rack 4.

[0022] Reference Figure 2 Two openings are provided on the side wall of the box body 1 directly above the cooling assembly 5. The openings penetrate the plate body on the top surface of the box body 1 and are arranged on the left and right sides of the cooling assembly 5. At this time, the air guide duct 6 is connected and installed between the two openings, so that a bypass airway can be formed at the position of the cooling assembly 5 for the subsequent direct backblowing operation of the solid-gas separation rack 4.

[0023] Reference Figure 3 An auxiliary air duct 10 is installed on the vertical side wall of the box body 1 located at the cooling component 5. In order to increase the coverage area of ​​backblowing, a through hole is also opened on the vertical side wall of the box body 1 to arrange another bypass air duct. At the same time, the auxiliary air duct 10 is exactly the same as the air duct 6 except for the different position. When backblowing, backblowing can be performed from the top and the rear side at the same time. Similarly, auxiliary air ducts 10 can be set at the bottom and the front side to perform backblowing dust removal on the four air outlets of the solid-gas separation rack 4, which greatly increases the backblowing coverage area and further improves the backblowing cleaning effect of the solid-gas separation rack 4.

[0024] Reference Figure 4 The air guide duct 6 includes a shell 62 that is set through. The shell 62 is a hollow rectangular shell with two 90-degree bent ports, which can be attached to the outer wall of the box body 1 for convenient fixed installation. At the same time, valve plates 1 61 and 2 63 are respectively installed at the port positions of the shell 62. When the exhaust gas is normally treated, valve plates 1 61 and 2 63 are closed, which can prevent the exhaust gas from directly contacting the blower 7 without passing through the cooling component 5, and can effectively ensure the normal cooling of the exhaust gas. When backblowing cleaning is performed, valve plates 1 61 and 2 63 are opened. At this time, the backblowing airflow generated by the blower 7 is blocked by the cooling component 5, and then it passes over the cooling component 5 from the position of the shell 62 to achieve smooth high-speed backblowing cleaning of the solid-gas separation frame 4.

[0025] Reference Figure 4 , wherein the valve plate 2 63 is located at the lower edge of the end of the shell 62 located in the relay section 8, and is located on the inner side of the box body 1, and the end of the valve plate 2 63 close to the solid-gas separation frame 4 can be driven to open and close. When the valve plate 2 63 is opened, it swings open in the direction away from the solid-gas separation frame 4, and can be opened sixty degrees to form an inclined guide surface, which bends the airflow blown out of the shell 62 toward the solid-gas separation frame 4, so that the airflow can be blown toward the solid-gas separation frame 4, which can improve the cleaning effect compared with the airflow parallel to the right side wall of the solid-gas separation frame 4.

[0026] Reference Figure 4 The cooling assembly 5 includes a main body 51, which is a serpentine tube group formed by winding pipes and has heat-conducting fins, which will block and slow down the airflow. A sealing plate 52 is installed in the gap between the main body 51 and the inner wall of the box body 1 to avoid leaving a gap between the inner wall of the box body 1 and the main body 51, ensuring that air can only pass through the main body 51 to the right to cool down.

[0027] Reference Figure 2 An air inlet is provided at one end of the air inlet section 2 of the box body 1, and a movable door 3 is installed at the air inlet of the box body 1. When there are many rolling body impurities in the exhaust gas, the movable door 3 can be closed. A mesh plate is embedded in the movable door 3. The exhaust gas is initially filtered through the mesh plate, which can reduce the filtering load of the solid-gas separation frame 4 and avoid the solid-gas separation frame 4 being blocked too quickly. At the same time, when there are fewer impurities in the exhaust gas, the movable door 3 can be opened to allow the exhaust gas to pass through at high speed, thereby improving the processing efficiency.
