Description

Technical Field

[0001] The utility model belongs to the technical field of heating, and particularly relates to an energy-saving and environmental-friendly heater for a distillation system, a heating system and a steaming furnace. Background Art

[0002] At present, in life and industrial production, steaming furnaces are often used, such as steaming rice and steamed buns in life, and steaming liquor in industrial production. When the existing steaming furnaces are heated, they are mostly heated at the bottom of the steaming furnace by means of electric heating, coal and firewood combustion heating, fuel oil heating, gas combustion heating, etc. Electric heating has good safety and no waste gas emission, but the heating speed is slower than that of gas combustion heating, the energy consumption ratio is larger than that of gas combustion heating, and the cost is also higher than that of gas combustion heating. In the heating methods of coal and firewood combustion and fuel oil heating, waste gas will be generated, which is not environmentally friendly. For gas heating, an open-air ignition heating method is adopted in the air. The heating speed and calorific value are higher than those of electric heating, and it is also relatively energy-saving. However, due to the open-air heating, the harmful gases that are not completely burned endanger human health, and the safety is relatively poor. In view of the above problems, the applicant applied for a Chinese utility model patent with the publication number of CN219217949U and the name of an energy-saving and environmental-friendly distillation heating system on September 30, 2022. In this heating system, an ignition chamber and a coil are arranged in a steamer pot filled with water. The coil is spirally placed in the water in the steamer pot. One end of the coil is connected to the ignition chamber, and the other end extends inside and outside the steamer pot. Natural gas is introduced into the ignition chamber, ignited and then sent into the coil, flowing and burning spirally in the coil. The water is indirectly heated by heating the coil until steam is generated. The natural gas combustion of the whole system is carried out in the coil, which greatly improves the safety and is energy-saving and environmental-friendly at the same time. In the subsequent production, the applicant found that the heating system, especially the coil (as shown in the physical diagram of the coil Figure 5 ), has the following deficiencies: the natural gas combustion efficiency is not ideal. Due to the large volume of the steamer pot and the large amount of water in it, from igniting the natural gas to heating the water in the steamer pot to boiling, the heating speed is slow and the time-consuming is long, about 35 minutes.

[0027] As Figures 1-4 shown, this embodiment provides an energy-saving and environmental protection distillation furnace for distilling wine, which includes a furnace body 16 and a heating system. The heating system includes an intake air blower and an energy-saving and environmental protection heater for the distillation system.

[0028] The furnace body 16 is selected as a conventional furnace body, and water is installed inside it.

[0029] The intake air blower is arranged on a preset bracket outside the furnace body 16, and an existing explosion-proof blower for combustible gas transmission is adopted. The intake end of the intake air blower is respectively connected to a gas pipeline and an air pipeline, and flow control valves are respectively arranged on the gas pipeline and the air pipeline. The intake air blower and the flow control valves are controlled by an automatic controller (a conventional controller is adopted).

[0030] The energy-saving and environment-friendly heat supply device of the distillation system includes an ignition chamber 1, an intake pipe 2, an exhaust pipe 3, an inner combustion ring 5, a diversion channel 6, an outer combustion ring 7, a transition combustion ring 8, and a smoke collecting pipe 4.

[0031] The ignition chamber 1 is a hollow cylinder with closed upper and lower ends, and its top is detachably covered with a cover plate. An ignition nozzle 9 for ignition is installed at the upper end inside the ignition chamber 1. The ignition nozzle 9 has a conventional structure and is used to ignite the mixed gas blown into the ignition chamber 1 by an intake air fan.

[0032] The outlet end of the intake pipe 2 (connected to the top cover plate of the ignition chamber 1) is connected to the upper end inside the ignition chamber 1 and is used to pump (send) the mixed gas composed of gas and air into the ignition chamber 1. The inlet end of the intake pipe 2 is connected to the outlet end of the intake air fan, and a flow control valve is provided on the intake pipe 2 to control the amount of gas entering the ignition chamber 1.

[0033] The inner combustion ring 5 is a hollow circular ring surrounding the outside of the ignition chamber 1 and concentric with the ignition chamber 1.

[0034] The diversion channel 6 is a plurality of ( Figure 2 shown as 25) hollow pipe bodies arranged radially and evenly between the ignition chamber 1 and the inner combustion ring 5 and connecting the lower end inside the ignition chamber 1 with the inside of the inner combustion ring 5. The diversion channel 6 is a trapezoidal plate-like structure with a hollow interior, the width of its upper base is smaller than that of its lower base, its upper base is connected to the lower end inside the ignition chamber 1, and its lower base is connected to the inside of the inner combustion ring 5. As Figure 2 shown, a strip-shaped through hole 13 is formed between adjacent diversion channels 6, and water enters the strip-shaped through hole 13 and is quickly heated, improving the heating efficiency.

[0035] The outer combustion ring 7 is a hollow circular ring surrounding the outside of the inner combustion ring 5 and concentric with the ignition chamber 1.

[0036] The transition combustion ring 8 is three hollow circular rings arranged concentrically outside the ignition chamber 1 from the inside to the outside in sequence, and all three transition combustion rings 8 are located between the inner combustion ring 5 and the outer combustion ring 7. There is no contact between the innermost transition combustion ring 8 and the inner combustion ring 5, between adjacent transition combustion rings 8, and between the outermost transition combustion ring 8 and the outer combustion ring 7, and annular through holes 12 are respectively formed. There are four diversion channels 11 respectively connecting between the innermost transition combustion ring 8 and the inner combustion ring 5, between adjacent transition combustion rings 8, and between the outermost transition combustion ring 8 and the outer combustion ring 7, that is, four diversion channels 11 are evenly distributed in each annular through hole 12; at the same time, the diversion channels 11 between adjacent annular through holes 12 are arranged staggeredly. Water enters the annular through hole 12 and is quickly heated, improving the heating efficiency.

[0037] The smoke collecting pipe 4 is communicated with the outer combustion ring 7 through four uniformly arranged smoke guiding pipes 10, and the smoke collecting pipe 4 is in a three-quarter arc shape.

[0038] One end of the exhaust pipe 3 is communicated with the smoke collecting pipe 4, and the other end extends to the outside of the room to discharge waste gas or send the waste gas to waste gas treatment.

[0039] The ignition chamber 1, the inner combustion ring 5, the shunt channel 6, the outer combustion ring 7, the transition combustion ring 8 and the diversion channel 11 are all placed in the furnace body 16 and immersed in water; the air inlet pipe 2 and the exhaust pipe 3 respectively pass through the holes preset in the upper part of the side wall of the furnace body 16 and extend to the outside. The inner combustion ring 5, the transition combustion ring 8 and the outer combustion ring 7 are all circular rings, and the three form a disc-shaped structure.

[0040] During use, water is added into the furnace body 16 to submerge the disc-shaped structure formed by the inner combustion ring 5, the transition combustion ring 8 and the outer combustion ring 7. After reaching a certain depth, the pot containing the material to be distilled is placed on the furnace body 16. After controlling the opening degrees of each flow control valve, the intake air blower is started. The intake air blower sends the mixed gas composed of combustible gas and air into the ignition chamber 1 through the air inlet pipe 2. The ignition nozzle 9 in the ignition chamber 1 ignites the mixed gas. The ignited mixed gas enters the lower end of the ignition chamber 1 under the blowing of the intake air blower, and then enters the shunt channel 6, and is dispersed into multiple strands of burning mixed gas by the shunt channel 6. Then the burning mixed gas converges into the inner combustion ring 5 and continues to burn. Then it sequentially enters each transition combustion ring 8 through the diversion channel 11 from the inside to the outside and gradually burns. Finally, it enters the outer combustion ring 7 to complete the final combustion and turn into smoke. The smoke in the outer combustion ring 7 enters the smoke collecting pipe 4, enters the exhaust pipe 3 through the smoke collecting pipe 4, and is discharged by the exhaust pipe 3. During the whole process, the combustible gas continuously burns efficiently in the energy-saving heating device of the distillation system, so that the inner combustion ring 5, the transition combustion ring 8 and the outer combustion ring 7 are continuously and rapidly heated, thereby realizing the heating of water. In addition, due to the existence of the annular through holes 12 and the strip-shaped through holes 13, the heating efficiency is further improved. Embodiment 2

The strip-shaped hole 14 divides the side of the shunt channel 6 close to the inner combustion ring 5 into two channels that are respectively connected to the inner combustion ring 5. The existence of the strip-shaped hole 14 can also enable water to enter it, thereby accelerating the increase of the water temperature. Embodiment 3

[0043] To further make the mixed gas burn fully, the following settings are added in this embodiment on the basis of Embodiment 1 or 2:

[0044] The distance between the inner circle and the outer circle of the outer combustion ring 7 is more than twice the distance between the inner circle and the outer circle of the transition combustion ring 8. Embodiment 4
