Description

Technical Field

[0001] The invention relates to the technical field of air ducts, and in particular to an intelligent wind control air duct with a built-in guide rod structure. Background Art

[0002] At present, in the layout and use of air ducts in many industries, problems such as uneven airflow distribution and serious deviation in the air ducts are encountered. For example, in the SCR equipment in the cement industry, the catalyst layer has high requirements for the uniformity of flue gas velocity and temperature, but the space of the SCR equipment itself is limited. Although there are guide plates, rectifier layers and other structures to homogenize the flue gas, when the flue gas in the air duct is seriously deflected, the effect is not obvious, which will accelerate the damage of the catalyst and cause significant losses. Therefore, it is necessary to control the uniformity of the flue gas in the air duct. The conventional measure is to install guide plates in the air duct to guide the flue gas. However, in addition to the need to stop production, resulting in losses and high construction costs, it may also be due to the complicated working conditions in the actual production process or other renovation construction that causes the flue gas deviation direction in the air duct to change, causing the original guide structure in the air duct to aggravate the deviation.

[0003] In the cement industry or other industrial fields, in addition to the control requirements for air flow distribution in the air duct, there are also corresponding requirements for controlling the air volume. The conventional measure is to install valves in the air duct and control the air volume by controlling the valve opening. However, the price of installing valves is relatively expensive, and it is found in actual application that conventional valves on the market, such as gate valves and shutter valves, will have a great impact on the flue gas flow field in the air duct. Therefore, conventional valves are not suitable for occasions where high requirements are placed on the uniformity of the flue gas flow field distribution.

[0004] Therefore, in order to solve the above problems, there is an urgent need to provide a multifunctional intelligent air control duct that can achieve uniform airflow distribution and control air volume. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides an intelligent wind control duct with a built-in guide rod structure, which can intelligently and automatically adjust the airflow velocity distribution in the duct according to the real-time smoke velocity distribution in the duct, thereby improving the uniformity of airflow distribution, and can replace the valve to achieve real-time control of the air volume. At the same time, the smoke diversion direction can be adjusted at any time according to actual needs, especially for some industries where the real-time working conditions in the air duct change greatly and frequently, and the demand for real-time guarantee of smoke uniformity or real-time control of air volume can be fully met.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1-Figure 10 ,

[0039] An intelligent air control duct 1 with a built-in guide rod structure, characterized in that it includes an air duct 1, a positioning support device, an intelligent guide rod group 3, and an intelligent monitoring system 4;

[0040] The positioning support device includes a guide rod positioning structure and a support rod group 2-4. The guide rod positioning structure includes a guide rod mounting seat and a support roller. The support rod group 2-4 is composed of a plurality of metal support rods. The metal support rods are welded to the air duct 1. The metal support rods are provided with a plurality of equally spaced arc grooves.

[0041] The intelligent flow guide rod group 3 consists of two parts: a flow guide rod and a traveling device 3-1. The flow guide rod group can be arranged in two groups in the air duct 1, or in one group. When arranged at the same time, the two groups of intelligent flow guide rod groups 3 need to be arranged perpendicular to each other. The intelligent flow guide rod group 3 has a sealing structure at the connection with the air duct 1.

[0042] The intelligent monitoring system 4 includes a speed monitoring module, a signal transmission module and a control module.

[0043] In the present invention, the guide rod mounting base is welded to the air duct 1 and is divided into two parts A and B: the first part mounting base A is installed on the outside of the air duct 1, and is composed of an arc-shaped sleeve and a support, and the arc diameter of the arc-shaped sleeve is D; the second part mounting base B is on the inside of the air duct 1, and is an arc-shaped metal base with the same axis and the same height as the first part, and the arc diameter of the arc-shaped metal base is the same as that of the first part, and the supporting roller includes an ordinary roller 2-5-2 and an elastic roller 2-5-1. An ordinary roller 2-5-2 is installed on the support, and multiple elastic rollers 2-5-1 are evenly distributed in the arc-shaped sleeve.

[0044] In the present invention, the common roller 2-5-2 is composed of a roller and a roller support, and the elastic roller 2-5-1 is based on the common roller 2-5-2, with a high elastic spring added between the roller and the roller support. When the roller is compressed, the roller can move along the direction of the spring compression.

[0045] In the present invention, the diameter of the arc groove on the metal support rod is d1, wherein d1≤D.

[0046] In the present invention, the traveling device 3-1 includes a device box, a traveling motor 3-1-4, a traveling gear 3-1-3, a traveling guide rail 3-1-2 and a traveling support wheel. The guide rod includes m metal round tubes with a diameter of d, wherein d < d1. The round tubes are not limited to standard models. According to the position of the round tubes, the lengths are L1, L2...Ln respectively. The traveling motor 3-1-4 is connected to the traveling gear 3-1-3. The motor rotates the gear to engage with the traveling guide rail 3-1-2 to move forward or backward, thereby realizing the guide rod entering and exiting the air duct 1. The traveling support wheel is fixed to the device box and installed at the lower end of the guide rod to support the guide rod to move forward or backward.

[0047] In the present invention, the traveling support wheel is a common roller 2-5-2.

[0048] In the present invention, the speed monitoring module is composed of a plurality of wind speed measuring devices 4 - 1 uniformly arranged in the circumference of the air duct 1 , which are respectively denoted as V1 , V2 , V3 . . . VnT1 , (T2 , T3 . . . Tn).

[0049] In the present invention, the speed monitoring module can be replaced by a temperature monitoring module, and the wind speed measuring device 4-1 can be replaced by a temperature measuring device.

[0050] In the present invention, the control logic of the intelligent wind control duct 1 is: when the speed monitoring module or the temperature monitoring module in the intelligent monitoring system 4 records the wind speed or temperature in the duct 1 and transmits it to the control module, when △V>Vm△T>Tm, where △V=Vmax-Vmin or △T=Tmax-Tmin, Vm / Tm is the set value, the control module issues an adjustment command, and the intelligent guide rod group 3 starts to run until △V≤Vm(△T≤Tm), and the adjustment stops.

[0051] Embodiment 1: This embodiment is mainly aimed at certain industries where the real-time working conditions in the air duct do not change much, there is no demand for real-time intelligent control, and there is only a demand for improving the flow field in the air duct and controlling the air volume, as well as controlling costs. The air duct form described in this embodiment can be used.

[0052] After on-site calibration, it was found that due to the deviation of the air flow in the original air duct, the wind speed on the A1 side of the air duct was much lower than that on the A3 side of the air duct, and the wind speeds on the A2 and A4 sides were basically similar. The main deviation of the air flow occurred in the A1 and A3 directions. Therefore, it is necessary to solve the deviation problem on the A1 and A3 sides, and at the same time, it is planned to consider reducing the amount of air entering the air duct. In view of the above problems, this embodiment only needs to use the first layer of the guide rod group to solve the problem: this layer is equipped with 5 guide rod mounting seats. After calculation, 3 DN300 steel pipes are selected as guide rods, which are installed on the A3 side. The guide rods are passed through the guide rod mounting seat A and placed on the corresponding arc groove of the metal support rod and the guide rod mounting seat B. In this embodiment, the 2-5-1 elastic roller is replaced with a locking bolt, and then the three guide rods are locked and fixed to the guide rod mounting seat A by the locking bolt. Subsequently, due to the effect of the guide rod, the airflow resistance on the A3 side is greatly improved, and the airflow tends to flow toward the A1 side, thereby changing the direction of the airflow in the air duct and making the flow field tend to be uniform; further, by selecting 3 DN300 steel pipes as guide rods, the ventilation area in the air duct is reduced by about 35%, which is equivalent to closing the valve by 35%, thereby achieving control of the air volume in the air duct.

[0053] Example 2: During the flow of air in the air duct, the wind speed measuring devices V1, V2, V3 and V4 in the intelligent monitoring system monitor and find that the speed on the V1 side is 10m / s, the speed on the V2 side is 12m / s, the speed on the V3 side is 18m / s, and the speed on the V4 side is 12m / s, then △V is 8m / s, and the set Vm is 5m / s, which is higher than the set value. Therefore, it is necessary to start the intelligent wind control device at this time, but because the wind speeds on the V2 and V3 sides are similar, it is also necessary to start the intelligent guide rod group that controls the airflow on the V1 and V3 sides. The speed monitoring module transmits the wind speed monitoring to the control module and issues an adjustment instruction. In this embodiment, a layer of intelligent guide rod group includes 5 groups. Since the speed monitoring module finds that the wind speed on the V3 side of the air duct is higher than the wind speed on the V1 side and the difference is higher than the limit value Vm, the intelligent guide rod group starts to start the adjustment, and changes the airflow direction by pushing the guide rod on the V3 side. When the speed △V≤Vm, the adjustment is completed.

[0054] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
