Description

Technical Field

[0002] During the winemaking process, the microorganisms in the anaerobic reactor need to be highly active at 35 degrees. Therefore, the fermentation liquid needs to be heated during winemaking to ensure that the temperature of the fermentation liquid is stable at 35-37 degrees when it enters the reactor.

[0003] Chinese patent CN208684971U discloses a combined anaerobic fermentation heating and insulation device, comprising a slurry heating tank for holding slurry and at least one heating component arranged on the periphery of the slurry heating tank; the heating component comprises a heater slurry inlet connected to the slurry heating tank, a steam heater, a heater slurry outlet connected to the slurry heating tank, and a steam inlet connected to the steam heater; the slurry flows from the slurry heating tank through the heater slurry inlet, the steam heater, the heater slurry outlet in sequence and then re-enters the slurry heating tank.

[0004] Among them, steam is introduced into the slurry to heat the slurry. This heating method has high thermal efficiency. However, when steam heating is performed, since the direct contact surface between the steam heater and water is too small and the amount of steam is large, it will generate a lot of noise and vibration, which has a great impact on the safety of people and equipment. At the same time, the direct introduction of steam makes it difficult for the steam to be evenly mixed with the slurry in the heating tank, resulting in uneven heating of the slurry.

[0020] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0022] See also Figure 1-Figure 3 As shown, the utility model is an anaerobic steam heater, comprising a heating tank 1, one end of the heating tank 1 is connected to a steam pipe 2, the end of the steam pipe 2 is connected to a nozzle 7 located inside the heating tank 1, and the nozzle 7 is provided with a liquid inlet hole 9 at one end opposite to the nozzle, and an axial flow mixing component located at one side of the steam outlet of the steam pipe 2 is installed inside the nozzle 7;

[0023] Among them, the steam pipe 2 is connected to the steam generator. When the solution in the heating tank 1 is heated, the high-temperature and high-pressure steam generated by the steam generator is first transported to the inside of the nozzle 7 through the steam pipe 2. At this time, the steam drives the axial flow mixing component to rotate, so that the axial flow mixing component sucks the solution in the heating tank 1 into the inside of the nozzle 7 through the liquid inlet hole 9, and fully mixes the steam and the solution through axial flow stirring. Finally, the mixed solution is sprayed into the heating tank 1 through the nozzle of the nozzle 7; by mixing the steam and the solution, the steam can be prevented from being directly sprayed into the solution, the noise and vibration generated during steam injection can be reduced, the safety during steam heating can be improved, and the uniformity of the solution heating can be improved. The solution can be driven to flow in the heating tank 1 through the axial flow mixing component, which has a stirring and circulation effect on the solution, so that the temperature of the solution in the heating tank 1 remains consistent, and temperature stratification will not occur, further improving the uniformity of the solution heating.

[0024] Specifically, the axial flow mixing assembly includes an axial flow blade 10 and a fixed ring 13, the fixed ring 13 is fixedly mounted on the inner wall of the nozzle 7, the axial flow blade 10 is arranged on the inner ring of the fixed ring 13, one end of the axial flow blade 10 is rotatably mounted with a support 11, and the support 11 and the fixed ring 13 are fixedly connected by a connecting frame 12;

[0025] When steam is sprayed onto the axial flow fan blades 10, the steam drives the axial flow fan blades 10 to rotate, and the rotation of the axial flow fan blades 10 generates negative pressure suction, which sucks the solution in the heating tank 1 into the nozzle 7 through the liquid inlet hole 9, and the steam and the sucked solution are fully mixed under the rotation and stirring of the axial flow fan blades 10, and finally sprayed into the heating tank 1 through the nozzle of the nozzle 7.

[0026] Specifically, a boost reducer 8 is fixedly installed at the steam outlet of the steam pipe 2, wherein the boost reducer 8 is a tapered pipe. By gradually reducing the pipe diameter, the pressure and speed of the steam in the steam pipe 2 can be increased when it is ejected through the boost reducer 8, thereby increasing the impact force of the steam on the axial flow fan blades 10, and further increasing the rotational stirring speed of the axial flow fan blades 10.

[0027] Specifically, a temperature sensor 6 extending into the interior of the heating tank 1 is fixedly installed at one end of the heating tank 1, and a solenoid valve 4 is fixedly installed on the steam pipe 2. The temperature sensor 6 and the solenoid valve 4 are connected by a signal line 5. The temperature sensor 6 can detect the temperature of the solution in the heating tank 1 and transmit the temperature data to the solenoid valve 4, so that the solenoid valve 4 can control the steam flow rate in the steam pipe 2 according to the solution temperature, and then control the temperature of the solution in the heating tank 1, so that the solution temperature is stabilized at 35-37 degrees, thereby preventing the anaerobic microorganisms from losing their activity due to excessive temperature in the solution.

[0028] Specifically, a liquid level sensor is also installed inside the heating tank 1. The liquid level sensor is connected to the solenoid valve 4 by signal. The liquid level sensor can detect the liquid level of the solution in the heating tank 1 and transmit the data to the solenoid valve 4, so that the solenoid valve 4 can control the steam flow rate in the steam pipe 2 according to the liquid level of the solution, thereby controlling the heating rate of the solution in the heating tank 1.

[0029] Specifically, a manual valve 3 is connected and installed on the steam pipe 2 , and the opening and closing of the steam pipe 2 can be controlled by the cooperation of the manual valve 3 and the solenoid valve 4 .
