Abstract
Description
Technical Field
[0001] The utility model is a distributor component used on a preheater, and relates to the field of preheaters. Background Art
[0002] The preheater uses the flue gas in the boiler's tail flue to pass through the internal fins to preheat the air before it enters the boiler to a certain temperature. This is used to improve the boiler's heat exchange performance and reduce energy consumption.
[0003] A distributor is required for preheater operation. Its function is to evenly distribute the liquid across the tower's cross-section, ensuring efficient operation. Currently, most distributors are showerhead, impingement, pagoda, multi-hole pipe arrangement, multi-hole coil, overflow tray, and overflow trough types. These distributors, when used within preheaters, have poor distribution effects, directly impacting preheater performance. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a distributor assembly for a preheater, which introduces liquid through a water inlet pipe, and evenly sprays the liquid to the bottom of the inner cavity through a guide pipe, a diversion pipe and a spray head. As the liquid is sprayed, the liquid is distributed through a V-shaped distribution plate to ensure that the liquid can be evenly distributed to the bottom of the inner cavity, thereby improving the distribution effect and the use effect of the preheater to solve the problems raised in the above background technology.
[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a distributor assembly for a preheater, comprising an outer fixing ring, an inner cavity is opened inside the outer fixing ring, the top and bottom of the inner cavity are both opened through, a guide pipe is fixedly connected to the inner wall of the top end of the inner cavity, a plurality of diversion pipes are evenly penetrated and fixedly connected on both sides of the guide pipe, a filter screen is fixedly connected to the inner wall of the bottom end of the inner cavity located at the guide pipe, and a plurality of V-shaped distribution plates are arranged on the top of the filter screen.
[0006] Furthermore, a plurality of sprinkler heads are evenly and fixedly connected to the bottom of the guide pipe and the diversion pipe.
[0007] Furthermore, the bottoms of the multiple V-shaped distribution plates are fixedly connected to a plurality of support columns, and the bottoms of the multiple support columns are fixedly connected to the top of the filter screen.
[0008] Furthermore, a water inlet pipe is fixedly connected to the side wall of the outer fixing ring that matches the position of the guide pipe, and the water inlet pipe passes through one end of the outer fixing ring and is fixedly connected to the guide pipe.
[0009] Furthermore, a water inlet valve is provided at one end of the water inlet pipe located on the outer fixing ring.
[0010] Furthermore, the guide tube and the diversion tube are evenly arranged in the inner cavity.
[0011] The beneficial effects of the utility model are as follows: the liquid is introduced through the water inlet pipe, and the liquid is evenly sprayed to the bottom of the inner cavity through the guide pipe, the diversion pipe and the spray head. As the liquid is sprayed, the liquid is distributed through the V-shaped distribution plate to ensure that the liquid can be evenly distributed to the bottom of the inner cavity, thereby improving the distribution effect and improving the use effect of the preheater.
