Description

Technical Field

[0001] This utility model relates to the field of biomass combustion technology, specifically an energy-saving built-in biomass combustion engine. Background Technology

[0002] With the tightening of energy conditions, including power shortages, oil shortages, rising electricity and oil prices, and the increasingly severe environmental pollution problems, various industries are gradually becoming more aware of the importance of renewable energy. Among these, biomass energy utilization is currently the most practical and feasible solution. Biomass combustion equipment is a semi-automatic biomass high-temperature pyrolysis burner that uses organic biomass such as biomass pellets, wood chips, wood powder, and sawdust as fuel. Its combustion costs are 75% lower than electricity, 50% lower than natural gas, and 40% lower than liquefied petroleum gas, and it is pollution-free, making it widely used.

[0003] Chinese patent CN217952262U discloses an energy-saving built-in biomass burner, including a burner body. A housing is installed at the exhaust end of the burner body's exhaust pipe. A dust filter element is detachably installed inside the housing. A duct is installed on the other side of the housing. The exhaust pipe is connected to the duct through the housing. The exhaust end of the duct penetrates the inner wall of one side of the feed hopper. An exhaust port is opened through the inner wall of the other side of the feed hopper. A feed trough is connected through one side of the inner wall at the top of the feed hopper. This invention, through the combination of the exhaust pipe, housing, and duct, can guide the smoke generated by the burner body into the housing. After being filtered by the dust filter element, the high-temperature flue gas is introduced into the feed hopper, which can heat and dry the biomass fuel in the feed hopper, preventing the biomass fuel from becoming damp and affecting its complete combustion.

[0004] The technical solution described in this plan involves filtering the smoke and dust generated by the combustion of the burner body through a smoke and dust filter element and then introducing it into the feed hopper to dry the biomass fuel. Although the flue gas is filtered before being introduced into the feed hopper, it still needs to be discharged after the biomass fuel is dried inside the feed hopper, resulting in a large amount of smoke and dust in the production workshop, which has a certain impact on the operators.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an energy-saving built-in biomass burner in order to achieve a more practical value. Utility Model Content

[0031] 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.

[0032] Please see Figure 1 - Figure 5The feeding box 2001 contains a screw feeder 2013. The input end of the screw feeder 2013 is connected to the bottom end of the material cylinder 2002. The bottom end of the material cylinder 2002 is equipped with a solenoid valve 2014. The output end of the screw feeder 2013 is connected to the burner body 1001. A water injection pipe 1003 is located on the upper side of one side of the burner body 1001. One end of the water injection pipe 1003 is connected to a water tank 1004.

[0033] Specifically, the working principle of this energy-saving built-in biomass burner is as follows: During use, the user injects water into the water tank 1004 through the water inlet pipe 1003. When combustion begins inside the burner body 1001, it heats the water tank 1004, raising the temperature of the water inside. At this time, the pump 2008 is activated to draw the hot water from the water tank 1004 into the heating tube 2011. The inner ring of the heating tube 2011 abuts against the outer wall of the material cylinder 2002, thus heating the material cylinder 2002 and drying the biomass pellets poured inside. Simultaneously, the servo motor 2007 is activated, causing the stirring rod 2009 to rotate, which stirs the biomass pellets inside the material cylinder 2002, improving drying efficiency. The water vapor generated during the drying process is dissipated by activating the exhaust fan 2006. The material is drawn out from inside the barrel 2002. One end of the heating tube 2011 is fitted with a pressure relief valve 2010, which is connected to the water tank 1004. This allows the water in the water tank 1004 and the heating tube 2011 to circulate. The pressure relief valve 2010 can prevent excessive pressure inside the water tank 1004 or the heating tube 2011 and can automatically relieve pressure. After drying, the user can open the solenoid valve 2014 to allow the material to enter the screw feeder 2013 from inside the barrel 2002. The screw feeder 2013 then feeds the material into the burner body 1001 for combustion. The water tank 1004 is equipped with a submersible liquid level sensor 1005, which can monitor the liquid level in the water tank 1004 in real time. The user can view the level through the touch panel 1002. The user can replenish the water tank 1004 in a timely manner through the water injection pipe 1003.
