Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a novel evaporator. Background Art

[0002] An evaporator is a tool that evaporates liquid to produce a large amount of steam through heat exchange. The steam produced can be used to steam wine, steam food, etc.

[0003] In the prior art, steam in large-scale distilleries is usually generated by steam engines and transported to corresponding locations through pipelines. A large amount of heat is lost during the transmission process. Ordinary evaporators are usually driven by electric heat, and the heating power is insufficient. In addition, ordinary evaporators have a small heat exchange area and cannot fully exchange heat. The amount of steam generated is insufficient. Therefore, an evaporator with high heating power and high heat exchange efficiency is needed. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a new evaporator.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A novel evaporator includes an evaporation head, which is placed in water. When in use, the evaporation head quickly heats water to evaporate and generate a large amount of steam. The evaporation head consists of an air inlet, a premixing burner, a primary heat exchange component, a secondary heat exchange component, and a smoke exhaust port. The air inlet enters premixed gas, which can be burned in a confined space. The air inlet is connected to the premixing burner, and the premixed gas enters the premixing burner through the air inlet. An igniter is provided in the premixing burner, and the igniter ignites the premixed gas to quickly release heat. The premixing burner is connected to the primary heat exchange component. The high-heat flue gas generated by the combustion of the premixed gas quickly exchanges heat with the outside through the primary heat exchange component, and water is evaporated to produce a large amount of water vapor. The primary heat exchange component is composed of at least one blade-type heat exchange tube. The blade-type heat exchange tube has a large contact area with the outside and a high heat exchange efficiency. The primary heat exchange component is connected to the secondary heat exchange component, and the secondary heat exchange component is composed of a smoke collecting pipe and a bellows. The flue gas that has undergone the first heat exchange passes through the smoke collecting pipe and the bellows for a second heat exchange, thereby improving the utilization rate of the flue gas heat. The bellows is connected to the smoke exhaust port, and the cooled smoke gas is discharged to the outside through the smoke exhaust port.

[0007] In one of the embodiments, the blade-type heat exchange tube is composed of a blade air inlet, a heat exchange blade, a heat exchange elbow, and a blade air outlet. The high-temperature flue gas generated by combustion enters the heat exchange elbow through the blade air inlet and then flows out from the blade air outlet. The heat exchange blade is a sheet-shaped rectangular and is located outside the heat exchange elbow. The heat exchange blade increases the heat exchange area of ​​the heat exchange elbow and improves the heat exchange efficiency. The curved pipe of the heat exchange elbow extends the flow distance of the flue gas, increases the area, and extends the heat exchange time, greatly improving the heat exchange efficiency, and can better utilize the heat of the flue gas to heat water to generate steam.

[0008] In one embodiment, the blade air inlet is connected to a premix burner, and the blade air outlet is connected to a smoke collection pipe. The high-temperature flue gas generated by combustion in the premix burner enters the primary heat exchange component through the blade air inlet, and the flue gas that has undergone the primary heat exchange enters the smoke collection pipe through the blade air outlet.

[0009] In one embodiment, the smoke collecting pipe is circular, the corrugated pipe is circular, and the smoke collecting pipe is located below the corrugated pipe. The smoke collecting pipe gathers the smoke flowing out of the blade-type heat exchange tubes at different positions and flows through the corrugated pipe. The corrugated pipe has many corrugations, which can greatly increase the contact area with the outside and improve the heat exchange efficiency. The gathered smoke flows through the corrugated pipe for secondary heat exchange, and the heat of the smoke is fully utilized to heat the water.

[0010] In one embodiment, the evaporation head is connected to a control cabinet, which transmits premixed gas to the evaporation head. The premixed gas is a gas that can be burned in a confined space. The flow rate and mixing ratio of the premixed gas are controlled by the control cabinet. The premixed gas burns and releases heat in the evaporation head, and the control cabinet controls the amount of heat.

[0011] In one of the embodiments, the control cabinet is connected to the evaporation head through an air intake pipe, the air intake pipe is located in an air intake trough, the air intake trough is located below the ground, the control cabinet is located above the ground, and the air intake pipe is buried under the ground through the air intake trough, thereby increasing the safety of the pipe. The method of transmitting the premixed gas to the evaporation head and then burning heated water to generate steam greatly reduces the waste of heat compared to the method of directly transmitting high-temperature steam to cook things, and makes the operation simpler, and there is no need to worry about condensed water affecting pipeline transmission.

[0012] In one embodiment, the evaporation head is located in a ground pot, which is circular and buried underground. The ground pot is filled with water, and the water in the ground pot is heated and boiled by the evaporation head to generate a large amount of steam.

[0013] In one embodiment, the ground pot is located under the ground, a smoke outlet trough is provided on the side of the ground pot, the evaporation head is connected to a smoke outlet pipe, and the smoke outlet pipe passes through the ground pot and the ground trough and leaks out above the ground. The smoke after two heat exchanges is discharged to the outside through the smoke outlet pipe.

[0014] In one embodiment, the premix burner is composed of a combustion head inner ring, a combustion head outer ring, a combustion liner, and an igniter. The combustion head outer ring protects the parts inside the premix burner and maintains the shape of the premix burner. The igniter is composed of an ignition needle, a fire tube, a fire chamber, and an ignition detection needle. When the premixed gas passes through the inner ring of the combustion head, an ignition detection needle is provided in the inner ring of the combustion head and connected to the ignition needle. The ignition detection needle of the igniter detects the premixed gas and cooperates with the ignition needle, the fire tube, and the fire chamber to ignite the premixed gas, so that the premixed gas is fully burned in the combustion liner and generates high-temperature flue gas that is transported to the primary heat exchange component and the secondary heat exchange component for heat exchange. At this time, the evaporation head dissipates a large amount of heat to the outside, causing the external water to boil and evaporate rapidly to generate a large amount of steam for processes such as steaming wine.

[0015] Beneficial effects of the utility model:

[0016] The utility model adopts the above technical scheme, the evaporation head is in the ground pot, the evaporation head is connected to the control cabinet through a pipeline, the control cabinet controls the heating power of the evaporation head, the premixed gas burns in the evaporation head to generate a large amount of heat, the high-temperature flue gas is heat-exchanged with external water through the primary heat exchange component and the secondary heat exchange component to quickly heat the water to generate a large amount of steam, so as to produce an evaporator with high heating power and high heat exchange efficiency. In places where steam cooking is required, such as breweries, the heat of the fuel can be utilized to the maximum extent, the heat loss during the transmission of the water vapor pipeline can be avoided, and there is no need to worry about the condensed water affecting the pipeline transmission, which has advantages in production efficiency and cost.
