Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production, in particular to a temperature-rising heating furnace. Background Technique

[0002] Under normal temperature and pressure, hydrogen is a gas that is extremely flammable, colorless, transparent, odorless and tasteless. Hydrogen is the lightest gas known in the world. Therefore, hydrogen can be used as the filling gas for airships and hydrogen balloons. When producing hydrogen, the off-gas generated during the production of methanol from coke oven gas can react with water vapor at high temperature to obtain water gas, so as to carry out subsequent hydrogen production work.

[0003] According to a disclosed temperature-rising heating furnace for hydrogen production (publication number: CN215893226U), in the above application, by driving the baffle plate and the stirring rod to rotate synchronously, the water in the heating furnace is fully stirred to be heated quickly and evenly, so as to improve the hydrogen production efficiency.

[0004] However, in the actual use process of the above equipment, there is no structure for turning the coal. When mixing the coal with water vapor, the water vapor can only contact a part of the coal, and the density of the water vapor is relatively light, so it will only adhere to the upper part of the equipment and cannot fully contact the coal to obtain water gas, which affects the hydrogen production efficiency. In view of this, we propose a temperature-rising heating furnace. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] As Figures 1-4 shown, the present invention provides a technical solution: a temperature-raising heating furnace, including a furnace body 1.

The inner wall of the furnace body 1 is fixedly connected with a ventilation net 4 later. The outer wall of the furnace body 1 penetrates and is fixedly connected with an air outlet 5. The inner wall of the air outlet 5 is fixedly connected with a filter screen 6. A vibration assembly 7 is arranged inside the furnace body 1. The vibration assembly 7 includes: a reciprocating motor 71, an electric push rod 72, a heating mesh 73, a baffle 74, a connecting shaft 75, a rotating shaft 76, a cleaning plate 77, and a limiting block 78. A fan assembly 8 is arranged inside the furnace body 1. The fan assembly 8 includes a swinging motor 81, a turntable 82, a slider 83, a connecting seat 84, a swinging shaft 85, a transmission column 86, a fan motor 87, and a fan blade 88.

[0023] In an embodiment of the present utility model, a reciprocating motor 71 is fixedly connected to the outer wall of the furnace body 1. The output end of the reciprocating motor 71 penetrates through the outer wall of the furnace body 1 and is fixedly connected to an electric push rod 72. The arc-shaped outer wall of the electric push rod 72 is fixedly connected to a heating grid 73. The outer wall of the heating grid 73 is fixedly connected to a baffle 74. One end of the baffle 74 close to the air outlet 5 is fixedly connected to a connecting shaft 75. The arc-shaped outer wall of the connecting shaft 75 is rotatably connected to a cleaning plate 77. The outer wall of the cleaning plate 77 is rotatably connected to a rotating shaft 76. One end of the heating grid 73 away from the electric push rod 72 is fixedly connected to a limiting block 78.

[0024] In an embodiment of the present utility model, a swing motor 81 is fixedly connected to the upper outer wall of the furnace body 1. The output end of the swing motor 81 penetrates through the upper outer wall of the furnace body 1 and is fixedly connected to a turntable 82. The lower end of the turntable 82 is fixedly connected to a slider 83. The center of the slider 83 penetrates and is slidably connected to a connecting seat 84. The outer wall of the connecting seat 84 is rotatably connected to a swing shaft 85. The lower end of the connecting seat 84 is fixedly connected to a transmission column 86. The lower end of the transmission column 86 is fixedly connected to a fan motor 87. The output end of the fan motor 87 is fixedly connected to a fan blade 88.

[0025] In addition, one end of the rotating shaft 76 away from the baffle 74 is fixedly connected to the inner wall of the furnace body 1. Both ends of the swing shaft 85 are fixedly connected to the inner wall of the furnace body 1. When the baffle 74 swings, the cleaning plate 77 rotates around the rotating shaft 76. When the slider 83 rotates with the turntable 82, the connecting seat 84 rotates around the swing shaft 85. The connecting seat 84 drives the transmission column 86 to swing, causing the fan to swing and blow the water vapor, so that it reacts more fully with the coal.

[0026] In an embodiment of the present utility model, the number of the heating grids 73 is set to two groups. The two groups of heating grids 73 are mirror-symmetrically distributed at the upper and lower ends of the baffle 74. The limiting block 78 is fixedly connected to the outer wall of the heating grid 73 at the lower end of the baffle 74. The heating grids 73 at the upper and lower ends are fixedly connected to the baffle 74. When the coal is placed in the heating grid 73, it can react with the water vapor.

[0027] In an embodiment of the present utility model, the filter screen 6 is fixedly connected to the inner wall of the edge of the air outlet 5 close to the inner wall of the furnace body 1, and the cleaning plate 77 is attached to the filter screen 6. When the cleaning plate 77 rotates, it can clean the filter screen 6.

[0028] In an embodiment of the present utility model, a chute matching the limiting block 78 is provided on the inner wall of the furnace body 1. The limiting block 78 is slidably connected to the inner wall of the chute to limit the heating grid 73, so that the heating grid 73 can move more smoothly, thereby making the coal turn over more smoothly without piling up in one place, and making the reaction between the coal and the steam more sufficient.

[0029] In an embodiment of the present utility model, the water inlet 2 is disposed on the inner wall of the furnace body 1 below the ventilation net 4, and the air outlet 5 is disposed on the inner wall of the furnace body 1 flush with the baffle 74. Water is poured into the furnace body 1 from the water inlet 2, and the water can evaporate into water vapor in the furnace body 1. The water vapor floats upward and reacts with coal to form water gas, and then passes out through the air outlet 5. The integrated device saves space.

[0030] In the present utility model, during use, water is poured into the furnace body 1 from the water inlet 2. The heating tube 3 inside the furnace body 1 heats the water to start evaporating water vapor. The water vapor floats into the heating net 73 from the ventilation net 4. The reciprocating motor 71 is started, and the reciprocating motor 71 causes the electric push rod 72 to quickly reciprocate and contract. The heating net 73 fixedly connected thereto reciprocates. At the same time, the limiting block 78 and the sliding groove on the heating net 73 enable the heating net 73 to move more smoothly, preventing coal from accumulating in one place. The reciprocating movement of the heating net 73 causes the coal on the heating net 73 to reciprocate accordingly, so that more coal can be contacted by the water vapor and the reaction is more sufficient. When the heating net 73 reciprocates, the connecting shaft 75 connected to the baffle 74 causes the cleaning plate 77 to reciprocally swing around the rotating shaft 76. The reciprocating swing of the cleaning plate 77 cleans the ash on the filter screen 6, preventing the ash from blocking the outlet and affecting the discharge of water gas from the air outlet 5. At this time, the swing motor 81 is started, and the swing motor 81 causes the turntable 82 to rotate, thereby causing the slider 83 to rotate. The slider 83 slides on the connecting seat 84 while rotating, and also causes the connecting seat 84 to swing around the swing shaft 85. The swing of the connecting seat 84 causes the transmission column 86 to drive the fan motor 87 to swing. The fan motor 87 causes the fan blade 88 to rotate, enabling the fan to blow the water vapor while reciprocating, so that the water vapor does not float upward all the time, enabling the water vapor to react with coal for a longer time and making the production efficiency of hydrogen higher.

[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
