The descaling pipe facilitates the installation of an ultrasonic descaling device. Multiple descaling pipes ensure effective descaling. Unused descaling pipes are sealed with plugs, guaranteeing equipment performance. The ultrasonic descaling device utilizes the cavitation effect of ultrasound.

For carbonate and iron oxide scale, acidic solutions such as hydrochloric acid can be used for cleaning. Generally, hydrochloric acid is prepared into a solution of a certain concentration (e.g., 5%-10%) and added to the bend using the acid-alkali filling structure. Corrosion inhibitors (such as hexamethylenetetramine) are added to prevent excessive corrosion of the boiler's metal pipes. The acid solution is injected into the boiler and circulated for a certain period. For sulfate scale, an alkaline boiling method can be used. Sodium hydroxide and sodium carbonate are prepared into a solution in a certain ratio (e.g., 1%-2% sodium hydroxide, 5%-10% sodium carbonate) and added to the bend using the acid-alkali filling structure. The solution is then injected into the boiler and heated. During the alkaline boiling process, the scale layer transforms under alkaline conditions, becoming looser and easier to clean subsequently.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 This utility model provides a device for purifying boiler water, including a pump body 1. One end of the pump body 1 is connected to the boiler through a pipe, and the other end of the pump body 1 is connected to a bend 2 through a flange. The bend 2 is a water supply pipe. Several descaling pipes 3 are uniformly fixed and connected to both sides of the bend 2. An ultrasonic descaling device 5 is screwed to the inner wall of one of the descaling pipes 3, and a plug 4 is screwed to the inner wall of the other descaling pipes 3. A first connecting pipe 7 is fixedly connected to the lower end of the side wall of the bend 2. A pH value measuring instrument 8 is screwed to the inner wall of the first connecting pipe 7. Second connecting pipes 9 are symmetrically assembled on the upper and lower sides of the first connecting pipe 7. Both second connecting pipes 9 are fixedly connected to the side wall of the bend 2, and an acid and alkali filling structure 6 is screwed to the inner wall of both second connecting pipes 9.

[0016] The pump body 1 connects to the water supply bend 2 and the internal pipeline of the boiler. The descaling pipe 3 facilitates the installation of the ultrasonic descaling device 5. Multiple descaling pipes 3 are installed to ensure effective descaling. Meanwhile, the plug 4 seals unused descaling pipes 3, ensuring the equipment's effectiveness. The ultrasonic descaling device 5 utilizes the cavitation effect of ultrasound. When ultrasound acts on the scale layer, tiny bubbles are generated inside the scale layer. The instantaneous bursting of these bubbles generates a powerful impact, causing the scale layer to detach from the inner wall of the pipe. The ultrasonic descaling device 5 can be laid out according to the pipeline, offering advantages such as no damage to the pipeline and good descaling effect. A pH meter 8 is installed through the first connecting pipe for convenient monitoring of the water's pH value. Controlling the pH value between 8 and 10 reduces acid corrosion and scaling problems. Two sets of acid-base injection structures 6 are set up, each controlling the pH level in its respective location. The internal system can be filled with acid and alkali reagents. Adding acid (such as hydrochloric acid) or alkali (such as sodium hydroxide) allows for precise pH adjustment. Simultaneously, the acid and alkali filling structure 6 can be used for descaling. For carbonate and iron oxide scale, acid solutions such as hydrochloric acid can be used for cleaning. Generally, hydrochloric acid is prepared into a solution of a certain concentration (e.g., 5%-10%) and added to the bend 2 using the acid and alkali filling structure 6. Corrosion inhibitors (such as hexamethylenetetramine) are also added to prevent excessive corrosion of the boiler's metal pipes. The acid solution is then injected into the boiler and circulated for a certain period. For sulfate scale, an alkaline boiling method can be used. Sodium hydroxide and sodium carbonate are prepared into a solution in a certain ratio (e.g., 1%-2% sodium hydroxide, 5%-10% sodium carbonate) and added to the bend 2 using the acid and alkali filling structure 6. This solution is then injected into the boiler and heated. During the alkaline boiling process, the scale layer transforms under alkaline conditions, becoming looser and easier to clean subsequently.

[0017] The acid-base filling structure 6 includes an injection pipe 61, which is screwed to the inner wall of the second connecting pipe 9. The outer end of the injection pipe 61 is fixedly connected to a storage cylinder 62. An electric telescopic rod 63 is fixedly connected through the inner wall of the storage cylinder 62. The piston rod end of the electric telescopic rod 63 is inserted into the storage cylinder 62 and a piston 64 is fixedly assembled thereon. The outer wall of the piston 64 is tightly fitted to the inner wall of the storage cylinder 62.

[0018] When the pH meter detects a problem with the pH value of the water, the controller is used to control the acid-base filling structure 6, which is filled with acid or alkali, to add solution into the bend 2 according to different needs, thereby adjusting the pH value of the water. First, the electric telescopic rod 63 is opened. The electric telescopic rod 63 controls the piston 64 to move towards the injection pipe 61 through the piston rod. The injection pipe 61 is equipped with a one-way valve, and the flow direction is that the storage cylinder 62 is facing into the bend 2. At this time, the acid and alkali solutions in the storage cylinder 62 enter the bend 2 through the one-way valve in the injection pipe 61 to adjust the acid-base balance.

[0019] A support 10 is snapped between the two acid and alkali filling structures 6.

[0020] Support 10 can ensure the stability of the two acid and alkali filling structures 6 during use.

[0021] A transparent plate 11 is fitted into the side wall of the storage cylinder 62.

[0022] The transparent plate 11 allows for easy observation of the remaining solution in the storage cylinder 62.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
