Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust-containing gas conveying pipelines such as activated carbon dioxin removal and dry desulfurization, and specifically is a multi-outlet dust-containing fluid distributor. Background Art
[0002] With the large-scale promotion of dry deacidification process, the waste gas purification process is increasingly used in large flue gas deacidification projects. Usually, the treatment requirements require a supporting baking soda, slaked lime, and activated carbon injection system. Usually, a single set of waste gas purification process is equipped with a desulfurizer injection system, and the waste gas purification process is equipped with a single reactor system. The contact surface between the desulfurizer and the reactor is very large. In order to spray the desulfurizer into the reactor so that the desulfurizer can better contact with the flue gas, the outlet conveying main pipe needs to be split into 3-4 injection pipes, and the reactor is equipped with 3-4 desulfurizer injection points. If a conventional tee is used for diversion at each diversion position, the conventional tee is prone to dust accumulation, easy to block, and frequent maintenance and clearing.
[0003] According to the search, Chinese patent literature, announcement number: CN214841831, discloses a fluid distributor, including a distributor body, in which a distribution chamber is arranged; a diverter element, which is arranged in the distribution chamber and divides the distribution chamber into a front chamber and a rear chamber; a liquid inlet pipe, which is connected to the front chamber; a plurality of distribution branches, which are connected to the rear chamber; the liquid inlet pipe and the plurality of distribution branches are parallel to the axis of the diverter element. The fluid distributor divides the liquid evenly, achieving good uniformity and stability, which can reach or even exceed the uniformity and stability of the existing Venturi distributor; furthermore, the heat exchanger using the liquid distributor can be evenly divided and the energy efficiency can be improved. The diverter element has a simple structure, is easy to process and mold, and has a low processing cost.
[0004] However, when the utility model is in use, it is easy to cause dust accumulation and blockage, and it is inconvenient to clean. In particular, baking soda and other powders with relatively small particle sizes and easily affected by moisture are particularly prone to blockage when conveying through the three-way. Utility Model Content
[0005] 1. Technical issues to be resolved
[0006] In view of the shortcomings of the prior art, the utility model provides a multi-outlet dust-containing fluid distributor, which adopts a centralized multi-point distribution method. The distributor is designed to be an elliptical arc. The arc-shaped structure is not easy to accumulate dust and blockage. In addition, it is equipped with an inspection hand hole for easy observation and clearing, thereby solving the above-mentioned technical problems.
[0007] (II) Technical solution
[0008] To achieve the above object, the utility model provides the following technical solution: a multi-outlet dust-containing fluid distributor, comprising an inlet main pipe, an inlet flange is installed on the outer surface of the inlet main pipe, a distributor is fixedly installed on the top surface of the inlet main pipe, and mutually symmetrical diversion pipes are fixedly installed on the top surface of the distributor;
[0009] An outlet flange is installed on the outer surface of the shunt pipe, and a wear-resistant rubber tube is connected to the end surface of the shunt pipe.
[0010] Preferably, the upper and lower ends of the distributor are elliptical in structure.
[0011] Through the above technical solution, by designing the two ends of the distributor into an elliptical arc, the inner wall can be made into a smooth surface, thereby reducing friction. Compared with the traditional right-angle tee, it avoids dust getting stuck in the corners, reduces dust accumulation, and reduces the possibility of blockage.
[0012] Preferably, a purge inspection hole is provided on the right side surface of the distributor.
[0013] Through the above technical scheme, by setting up the purge inspection hole, it is convenient for the operator to observe the situation inside the distributor, so as to make timely judgments and adjustments, and the purge inspection hole can be used to clean the inside of the distributor, avoiding dust accumulation caused by long-term use, thereby increasing the service life of the equipment.
[0014] Preferably, the distributor, the inlet main pipe and the diversion pipe are designed in a suitable proportion.
[0015] Through the above technical scheme, by designing different sizes of the device according to different flow rates, according to the requirements of the required multi-point distribution, and according to the actual situation, it is designed according to twice the inlet pipe diameter. When 4-point or 5-point distribution is required, the diameter of the multi-point distributor can be changed to 2.5 or 3 times, thereby improving the practicality of the device.
[0016] Preferably, the wear-resistant rubber tubes are arranged with equal lengths.
[0017] Through the above technical solution, by adopting wear-resistant rubber tubes with equal length, the resistance along the distributor to the injection point can be ensured to be the same, thereby ensuring that the dust-containing fluid can be evenly ejected from the injection port, thereby improving the stability of the device during diversion.
[0018] Preferably, the diverter pipes are evenly distributed on the top of the distributor.
[0019] Through the above technical solution, by evenly arranging the diversion pipes, the dust-containing fluid can be evenly sprayed out from the inside. Usually, a single exhaust gas purification process is equipped with a desulfurizer injection system. The exhaust gas purification process is equipped with a single reactor system. The contact surface between the desulfurizer and the reactor is very large. In order to spray the desulfurizer into the reactor so that the desulfurizer can better contact with the flue gas, the outlet conveying main pipe needs to be diverted into multiple injection pipes.

[0021] 1. The utility model designs the two ends of the distributor into an elliptical arc shape, so that the inner wall can be a smooth surface, thereby reducing friction. Compared with the traditional right-angle tee, it avoids dust getting stuck at the corners, reduces dust accumulation, and reduces the possibility of blockage. In addition, by setting a purge inspection hole, it is convenient for the operator to observe the situation inside the distributor, so as to make judgments and adjustments in time. The purge inspection hole can be used to clean the inside of the distributor, avoiding dust accumulation caused by long-term use, thereby increasing the service life of the equipment.
[0022] 2. The utility model designs the device in different sizes according to different flow rates and the requirements of multi-point distribution according to actual conditions. Generally, it takes twice the inlet pipe diameter. When 4-point or 5-point distribution is required, the diameter of the multi-point distributor can be changed to 2.5 or 3 times, so as to improve the practicality of the device. In addition, by adopting wear-resistant rubber tubes with equal lengths, it can be ensured that the resistance along the way from the distributor to the injection point is the same, thereby ensuring that the dust-containing fluid can be evenly ejected from the injection port, thereby improving the stability of the device during diversion.
