Description

Technical Field

[0001] The utility model relates to the technical field of gasifiers, and in particular to a heating system utilizing aquaculture waste and foreign matter. Background Art

[0002] A gasifier is a device that can convert solid fuels (such as coal, biomass) into combustible gases (such as synthesis gas, coal gas). Through gasification reaction, it decomposes solid fuels into gas and ash in an oxygen-deficient or oxygen-restricted environment. The gas mainly includes combustible gases such as carbon monoxide, hydrogen, and methane. A large amount of aquaculture waste foreign matter will be produced in the farm, such as animal manure (cow dung), feed residues, etc. If the aquaculture waste is not properly handled, it will lead to water and soil pollution and have a negative impact on the ecological environment. Therefore, our company intends to use aquaculture waste foreign matter as solid fuel for gasification furnace to convert combustible gas for heating. Aquaculture waste foreign matter will produce a certain amount of sulfide after gasification reaction, so it is necessary to desulfurize the converted combustible gas. On the other hand, it is necessary to consider how to improve the thermal utilization rate. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0018] like Figure 1 As shown, according to the utility model, a heating system utilizing aquaculture waste foreign matter is disclosed, including a gasifier 100 and a boiler 200, wherein the gasifier 100 includes a furnace body 110 with a heat insulation function, wherein a gasification chamber 120 is arranged in the furnace body 110, and a preheating water pipe close to the gasification chamber 120 is arranged between the furnace body 110 and the gasification chamber 120, wherein the output end of the preheating water pipe is connected to the furnace core 210 inside the boiler 200 through a water pipe 130, and the upper end of the gasifier 100 is connected to the desulfurizer 300 through a flue gas duct 140, and the other end of the desulfurizer 300 is connected to a combustion furnace 400 through a pipeline, and the combustion furnace 400 is located below the furnace core 210.

[0019] Embodiment 1:

[0020] In the present application, solid fuel is added into the gasification chamber 120 through the discharge port 111 (cow dung can be used as the solid fuel, and a small amount of small-grained bituminous coal, etc., can be mixed into the solid fuel to further improve the quality of the solid fuel), and a vibrator 112 is installed on the outer wall of the furnace body 110. The solid fuel can better fill the gasification chamber 120 through vibration by the vibrator 112 (in order to prevent the vibration from affecting the connected water pipe and air intake pipe, the input end of the preheating water pipe is connected to the water supply device through a hose, the output end of the preheating water pipe is connected to the water pipe through a hose, and the input end of the air intake pipe is connected to the air supply device through a hose), and the fixed fuel undergoes an oxygen-deficient or oxygen-limited gasification reaction in the gasification chamber 120 to generate combustible gas (the oxygen flow rate is controlled by the air intake pipe 122), and the generated combustible gas enters the desulfurizer 300 through the flue gas duct 140. After the gasification reaction is completed, the ash outlet 121 is opened to allow the ash to enter the ash cleaning chamber 150 and be finally removed by the ash outlet auger 151. In addition, a preheated water pipe is provided between the furnace body 110 and the gasification chamber 120, and the heat generated during the gasification reaction in the gasification chamber 120 can be absorbed by the water in the preheated water pipe, and then the preheated water will enter the furnace 210 of the boiler 200, thereby improving the heat utilization rate. As can be seen from the figure, the water is first preheated in the gasifier 100, and then enters the furnace 210 through the water pipe 130 for heating, and after being heated to the set value, it is transported to the heating area 600 through the heating pipe 211 for heating, and the water with a lowered temperature finally re-enters the gasifier 100 through the water inlet 113 through the circulation pump 700 for preheating, thereby circulating the process.

[0021] The combustible gas output from the flue gas duct 140 contains sulfide and smoke particles. The combustible gas enters the desulfurizer 310 in the desulfurizer 300 for desulfurization and removal of smoke particles (at the same time, the induced draft fan 500 induces air to mix the combustible gas to achieve full combustion, solving the odor generated when the flue gas is discharged). A sensor 340 is provided at the bottom of the inner cavity of the desulfurizer 300. After the sensor 340 detects that the desulfurization effect of the desulfurizer 310 has reached saturation, it is discharged through the sewage outlet 330, and then new desulfurizer is added through the desulfurizer addition port 320. The combustible gas enters the combustion stove 400, and the furnace plate of the combustion stove 400 is ignited to add heat to the furnace 210. When the water in the furnace 210 is heated to the set temperature, it is output through the heat supply pipe 211 for heat supply, and the combustion exhaust gas is discharged from the chimney 220.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
