Abstract
Description
本发明涉及一种旋流密封吸气装置。特别是一种能远距离有效地控制污染源，并且吸风量小的吸气装置。适合于对有害气体污染源吸气的场合。The invention relates to a swirl sealing suction device. In particular, it is an air suction device that can effectively control pollution sources at a long distance and has a small suction volume. It is suitable for occasions where harmful gas pollution sources are inhaled.
现有吸气装置一般为单一的吸气方式，这类吸气装置的吸风量与该装置距污染源的距离成平方关系，距离越远，混入空气越多。例如有移动吊车、小车等，为了不影响工艺操作，一般吸气装置安装距污染源较远，吸风量较大。根据日本资料介绍，日本生产一种龙卷风原理的风幕机。该机有四根吹风立管和一个顶部吸风口。它可以距污染源较远，用较少风量有效地控制污染源。但该装置造成龙卷风的四根立管，对工艺操作仍然有一定影响。Existing air suction devices generally use a single air suction method. The air suction volume of this type of air suction device is in a square relationship with the distance between the device and the pollution source. The farther the distance is, the more air will be mixed. For example, there are mobile cranes, trolleys, etc. In order not to affect the process operation, the suction device is generally installed far away from the pollution source, and the suction volume is relatively large. According to Japanese data, Japan produces an air curtain machine based on the principle of a tornado. The machine has four blowing risers and a top suction port. It can be far away from the pollution source and effectively control the pollution source with less air volume. But this device causes four standpipes of tornado, still has certain influence to technological operation.
本发明的目的，是提出一种新的吸气装置。该装置即能远距离控制污染源，风量少，同时又不影响工艺操作的吸气装置。The purpose of this invention is to propose a new suction device. The device is a suction device that can control the pollution source from a long distance, has a small air volume, and does not affect the process operation at the same time.
本发明的目的是以如下方式实现的：在一个吸气装置吸气口的外周，设置一个环形的吹风口，该环形吹风口设置若干个导风叶片，导风叶片安装成一定角度，使吹出的风形成旋转运动气流。其环形旋转气流流线为螺旋线。环形旋转气流隔阻了外界空气的混入。旋转气流的离心作用，在环形中心形成一定的负压。将负压中心对着污染源，通过吸气口吸气，即可用较少风量，远距离、高效率地控制污染源。The purpose of the present invention is achieved in the following manner: on the periphery of the suction port of a suction device, an annular blowing port is set, and the annular blowing port is provided with several wind guide vanes, which are installed at a certain angle so that the blown out The wind forms a swirling airflow. Its annular rotating air flow line is a helix. The circular swirling airflow blocks the mixing of outside air. The centrifugal effect of the rotating air flow forms a certain negative pressure in the center of the ring. Point the negative pressure center to the pollution source, and inhale through the suction port, so that the pollution source can be controlled remotely and efficiently with less air volume.
本发明与现有吸气装置比较，具有能远距离，有效地控制污染源，吸气量少，不影响工艺操作的特点。Compared with the existing air suction device, the present invention has the characteristics of being able to control pollution sources effectively at a long distance, with less air suction and no influence on process operation.
以下将结合附图对本发明作进一步详细描述。The present invention will be described in further detail below in conjunction with the accompanying drawings.
图1是本发明一种典型实施装置的正面视图。Figure 1 is a front view of a typical embodiment of the present invention.
图2是图1的本发明实施装置沿C-C线的剖视图。Fig. 2 is a cross-sectional view of the device for implementing the present invention in Fig. 1 along line C-C.

参照图1、图2、图3，一个旋流密封吸气装置（1），在该装置中部设有吸气口（2），吸气口外周有一环形送风管（3），送风管开有环形吹风口（4）。在环形吹风口设置有若干导风叶片（5），导风叶片与环形吹风口中心线成一定角度安装。吸气口通过管道与负压气源（6）相连接，吹风管与正压气源（7）相连接。该装置安装在污染源（8）附近不影响工艺操作的位置。装置的吸气口对着污染源。由于倾钭安装的导风叶片作用，吹风口吹出的气流，为环形旋转气流，其流线为螺旋线（9）。环形旋转气流隔阻了外界空气的混入，故减少吸风量。由于旋转气流的离心力作用，在环形旋转中心产生对应的与离心力平衡的负压。通过吸气口的负压克服旋转气流中心负压阻力，将污染源的有害气体，通过旋转气流中心、吸气口到负压气源系统中。Referring to Figure 1, Figure 2, and Figure 3, a swirl seal air suction device (1) is provided with an air suction port (2) in the middle of the device, and there is an annular air supply pipe (3) around the air suction port, and the air supply pipe Have annular air blowing port (4). A plurality of wind guide vanes (5) are arranged at the annular blowing outlet, and the wind guiding vanes are installed at a certain angle to the center line of the annular blowing outlet. The suction port is connected with the negative pressure air source (6) through the pipeline, and the blowing pipe is connected with the positive pressure air source (7). The device is installed near the pollution source (8) where it does not affect the process operation. The suction port of the device faces the pollution source. Due to the effect of the wind guide vanes installed at an angle, the airflow blown out from the blower port is an annular swirling airflow, and its streamline is a helical line (9). The circular swirling airflow blocks the mixing of outside air, thus reducing the suction volume. Due to the centrifugal force of the rotating air flow, a corresponding negative pressure balanced with the centrifugal force is generated at the center of the annular rotation. The negative pressure through the suction port overcomes the negative pressure resistance of the rotating air flow center, and the harmful gas from the pollution source passes through the rotating air flow center and the suction port to the negative pressure air source system.
