Description

Technical Field

[0001] The invention relates to the technical field of boilers, in particular to an energy-saving device suitable for a boiler water system. Background Art

[0002] A boiler is an energy conversion device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium (such as water, organic heat carrier, etc.) to a certain temperature to produce steam, hot water or other heat media with a certain temperature and pressure. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. A boiler that generates steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.

[0003] Existing boilers transfer the heat energy released after fuel combustion or the waste heat in industrial production to the water in the container. The boiler operates in both the "pot" and the "furnace" parts at the same time. After the water enters the boiler, the boiler heating surface transfers the absorbed heat to the water, heating the water into hot water of a certain temperature and pressure or generating steam, which is then led out for use. In the combustion equipment part, the fuel combustion continuously releases heat, and the high-temperature flue gas generated by the combustion transfers the heat to the boiler heating surface through heat transfer, while its own temperature gradually decreases and is finally discharged from the chimney. In this process, sewage needs to be discharged continuously. After purification, the sewage is often reused in the boiler, but workers often put in too much reagent at one time, resulting in too much purification reagent in the sewage and affecting its recycling.

[0015] Working principle: When the device is needed, first drain the sewage inside the boiler body to the inside of the heat exchange box through water pipe 1, and then drain the sewage to the inside of the purification box through water pipe 2, and then start the double-headed motor to drive the rotating rod 1 to rotate, and then the rotating shaft 1 rotates synchronously under the drive of the rotating rod 1, and then the rotating rod 2 rotates under the drive of the rotating shaft 1, at this time, the rotating shaft 2 rotates synchronously under the drive of the rotating rod 2, and then the transmission rod rotates around the rotating shaft 3 under the drive of the rotating shaft 2, and then the rotating column 1 rotates synchronously under the drive of the transmission rod, and then the rotating rod 3 rotates around the rotating column 2 under the drive of the rotating column 1, and at this time the slider is rotating The medicine dissolves the scale inside the sewage and reduces the salt content of the sewage. At this time, the reciprocating slider is stuck in the medicine delivery tube to change the size of the medicine outlet of the medicine delivery tube, and finally the purpose of controlling the medicine delivery speed is achieved, so as to ensure the uninterrupted addition of medicine to the sewage to maintain the concentration of medicine and avoid the effect of excessive medicine in the sewage to affect the recycling effect; the lower output end of the double-headed motor drives the transmission column to rotate inside the purification box, and then the stirring blade rotates driven by the transmission column. The stirring of the mixing blades and the dosing are carried out simultaneously, and finally the purpose of uniform mixing of the chemicals inside the sewage is achieved, so as to achieve the effect of ensuring the uniform concentration of the chemicals inside the purification box; after the sewage is purified by the purification box, the pump connected to the pumping pipe 1 is started, and the pump draws the purified sewage into the recovery box. Due to the high residual heat of the sewage inside the heat exchange box, the liquid inside the recovery box is preheated, and then refluxed to the inside of the boiler body through the water pipe 3, and finally the initial temperature of the boiler inlet water is increased, so as to achieve the effect of reducing the energy consumption of the boiler and recycling water resources; by installing A filter is installed, and several water inlet holes are opened on one side of the heat exchange box. The water inlet holes are used to support a water pipe. The water pipe is used to drain the sewage heated by the boiler body into the heat exchange box. The filter is used to screen out large scale in the sewage. At the same time, several water outlet holes are opened on the other side of the heat exchange box. The water outlet holes are used to support a water pipe. The water pipe is used to drain the sewage after preliminary filtration into the purification box. Then, a filter is installed inside the purification box. The filter further screens out scale. After being filtered by the filter and the filter, the scale density inside the sewage is reduced, thereby achieving the effect of reducing the consumption of chemicals.

[0016] The present invention provides an energy-saving device suitable for a boiler water system. It has the following beneficial effects: 1. The sewage generated by the boiler body after heating is discharged into the heat exchange box through the water pipe 1, and then the sewage in the heat exchange box is discharged into the purification box through the water pipe 2. At this time, the double-headed motor is started to drive the rotating rod 1 to rotate, and finally the purpose of controlling the medicine discharging speed is achieved, thereby ensuring that the medicine concentration is maintained at the position where the medicine is added to the sewage uninterruptedly, and avoiding the effect of excessive medicine in the sewage affecting the recycling.

[0017] 2. The present invention drives the transmission column to rotate along the inner wall of the purification box through the lower output end of the double-headed motor. The transmission column is used to drive the stirring blade to rotate synchronously. Since the output ends on both sides of the double-headed motor rotate synchronously, the rotation of the stirring blade is synchronized with the dosing. The stirring blade is used to break up and mix the administered medicine into the sewage, ultimately achieving the purpose of uniform mixing of the medicine inside the sewage, thereby achieving the effect of ensuring the uniform concentration of the medicine inside the purification box.

[0018] 3. The present invention uses a purification box to remove scale inside the sewage and then starts a pump connected to the pumping pipe one. At this time, the sewage after descaling is recycled into the recovery box. Since the sewage discharged from the boiler body to the heat exchange box has a relatively high heat, the residual heat of the sewage is used to preheat the liquid inside the recovery box. Part of the water will be lost in the recycling process of the sewage. At this time, the water pump connected to the pumping pipe two is started to replenish the water source inside the water storage tank to the recovery tank through the pumping pipe two. At the same time, the sewage is mixed with the water replenished from the water storage tank in the recovery tank and preheated. Then the mixed liquid flows back to the inside of the boiler body through the water supply pipe three, thereby finally achieving the effect of increasing the initial temperature of the boiler inlet water, thereby achieving the effect of reducing the energy consumption of the boiler and recycling water resources.

[0019] 4. The present invention installs a filter mesh 1 inside the heat exchange box, and the filter mesh 1 is used to screen out large scale in the sewage. Then, a filter mesh 2 is installed inside the purification box, and the filter mesh 2 further screens out scale. After being filtered by the filter meshes 1 and 2, the scale density inside the sewage is reduced, thereby achieving the effect of reducing the consumption of chemicals.
