AI Technical Summary
In existing hydrolysis furnaces, the steam heater condenses into water droplets during the heating process, causing water to accumulate at the bottom of the cylinder. This affects the sensitivity and detection results of the temperature sensor, leading to unstable operation of the heater.
A baffle plate is installed inside the cylinder and a drainage groove is opened at its bottom. The thermometer is tilted and fitted with an outer sleeve to prevent water accumulation and droplets from affecting the thermometer. Water is drained through the drainage groove. The tilted thermometer prevents droplets from lingering, and the sleeve protects the thermometer from direct contact with steam and water.
It effectively prevents water accumulation and droplets from affecting heater operation, maintains thermometer sensitivity and accuracy of detection results, avoids thermometer malfunction, and ensures stable heater operation.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrolysis furnace technology, specifically a steam heater for a hydrolysis furnace. Background Technology
[0002] Existing steam heaters for hydrolysis furnaces, such as Figure 1 , Figure 2 As shown, it includes a cylinder 1, a heating tube 2 is provided inside the cylinder 1, a junction box 3 electrically connected to the heating tube 2 is installed at one end of the cylinder 1, a steam inlet is provided at the bottom of one end of the cylinder 1, a steam outlet 5 is provided at the top of the other end of the cylinder 1, a first temperature sensor 8 is installed at the steam outlet 5, and a second temperature sensor 9 is provided at the other end of the cylinder 1.
[0003] However, in this type of hydrolysis furnace steam heater, steam may condense into water droplets inside the cylinder during the heating process. After prolonged operation, water will accumulate at the bottom of the cylinder, affecting the heater's operation. Furthermore, larger droplets formed by steam condensation remaining on the surface of the temperature sensor can affect its sensitivity. Additionally, the release of heat from steam condensation on the temperature sensor's sensing element or the absorption of heat by the evaporation of droplets will both affect the sensor's detection results, thus impacting the heater's operation. Summary of the Invention
[0004] To address the drawbacks of existing steam heaters for hydrolysis furnaces, where water accumulates at the bottom of the inner cylinder, and the steam and its condensed droplets affect the sensitivity and detection results of the temperature sensor, thus impacting the heater's operation, this invention provides a steam heater for hydrolysis furnaces that prevents steam and liquid from affecting its operation.
[0005] A steam heater for a hydrolysis furnace includes a cylindrical body, a heating tube disposed inside the cylindrical body, a junction box electrically connected to the heating tube installed at one end of the cylindrical body, a steam inlet at the bottom of one end of the cylindrical body, and a steam outlet at the top of the other end of the cylindrical body. Baffles are arranged sequentially along a horizontal direction inside the cylindrical body, and each baffle has a baffle hole. The baffles are characterized by having a drainage groove at their bottom; a drainage outlet at the bottom of the other end of the cylindrical body; a first thermometer installed at the steam outlet; and a second thermometer disposed at the other end of the cylindrical body. Both the first and second thermometers are rod-shaped, with their sensing elements located at their bottoms. The sensing element of the first thermometer extends into the steam outlet, and the sensing element of the second thermometer extends into the other end of the cylindrical body. The output element of the first thermometer extends out of the steam outlet, and the output element of the second thermometer extends out of the cylindrical body. The first and second thermometers are arranged at an angle.
[0006] Its further features are:
[0007] The angle between the first thermometer and the second thermometer and the vertical direction is 45°;
[0008] The projections of the first thermometer and the second thermometer in the horizontal direction are perpendicular to each other.
[0009] The first thermometer and the second thermometer are fitted with sleeves.
[0010] With the above-described structure of this invention, a drainage groove is provided at the bottom of the guide plate, allowing water accumulated inside the cylinder to drain out through the drain outlet, preventing water accumulation from affecting the operation of the steam heater for the hydrolysis furnace. The thermometer is rod-shaped and tilted, allowing liquid on its surface to slide off under gravity, preventing droplets from remaining on the thermometer for extended periods and affecting sensitivity and detection results. The first and second thermometers are projected perpendicularly to each other in the horizontal direction, preventing mutual obstruction and further avoiding impact on thermometer sensitivity and detection results. The sleeve protects the first and second thermometers from direct contact with steam and water, further preventing interference with thermometer sensitivity and detection results.

[0017] See Figures 3 to 5 A steam heater for a hydrolysis furnace includes a cylindrical body 1, a heating tube 2 disposed inside the cylindrical body 1, a junction box 3 electrically connected to the heating tube 2 installed at one end of the cylindrical body 1, a steam inlet at the bottom of one end of the cylindrical body 1, a steam outlet 5 at the top of the other end of the cylindrical body 1, baffles 6 arranged sequentially along the horizontal direction inside the cylindrical body 1, baffles 6 having baffle holes 7, and a drainage groove 10 at the bottom of the baffles 6; and a drain outlet 16 at the bottom of the other end of the cylindrical body 1.
[0018] See Figure 6 A first thermometer 11 is installed at the steam outlet 5, and a second thermometer 12 is installed at the other end of the cylinder 1. The first thermometer 11 and the second thermometer 12 are rod-shaped. The temperature sensing element 14 of the first thermometer 11 and the second thermometer 12 is located at the bottom. The temperature sensing element 14 of the first thermometer 11 extends into the steam outlet 5, and the temperature sensing element 14 of the second thermometer 12 extends into the other end of the cylinder 1. The output element 15 of the first thermometer 11 extends out of the steam outlet 5, and the output element 15 of the second thermometer 12 extends out of the cylinder 1, which facilitates manual inspection by staff and prevents the output element 15 from malfunctioning due to steam and high temperature.
[0019] The first thermometer 11 and the second thermometer 12 are tilted. In the figure, angles α and β are the angles between the first thermometer 11 and the second thermometer 12 and the vertical direction, respectively, and both angles α and β are 45°.
[0020] The projections of the first thermometer 11 and the second thermometer 12 in the horizontal direction are perpendicular to each other to prevent mutual obstruction from affecting the detection results.
[0021] The first thermometer 11 and the second thermometer 12 are fitted with sleeves 13 to protect them from direct contact with steam and water.
[0022] The first thermometer 11, the second thermometer 12 and the central control system are electrically connected (not shown in the figure), and the heating tube 2 is electrically connected to the central control system through the junction box 3.
[0023] In operation, steam enters the cylinder 1 through the steam inlet 4. The baffle 6 guides the steam to diffuse evenly within the cylinder 1, allowing it to travel from one end to the other. During this process, the steam is heated to a specified temperature by the heating tube 2. A first thermometer 11 detects the temperature of the steam exiting from the steam outlet 5, and a second thermometer 12 detects the temperature of the steam reaching the other end of the cylinder 1. These thermometers transmit the temperature information to the central control system in real time. The central control system then controls the heating tube 2 based on this information to maintain the heated steam temperature within a specified range. Water droplets formed by condensation on the inner wall of the cylinder 1 slide down to the bottom and drain through the drain outlet 16 along the drain groove 10. Liquid on the surfaces of the first and second thermometers 11 and 12 can also slide down under gravity and drain from the drain outlet 16.
