DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As attached Figures 1 to 4 The heater shown is for treating waste gas from the production of sodium saccharin. It includes an outer shell 1 and an inner shell 2 inside the outer shell 1. The outer wall of the inner shell 2 is corrugated. Two connecting plates 3 are symmetrically fixed on the outer wall of the inner shell 2, and a compression rod 4 is fixedly connected to the surface of each connecting plate 3. A compression spring 5 is sleeved on the outer side of the compression rod 4. A stop block 6 is fixedly connected to the outer wall of the compression rod 4. A pressure sensor 7 is connected to the outer wall of the outer shell 1 through a connecting frame 10, and the connecting frame 10 is fixed to the outer wall of the outer shell 1 by bolts. The end of the compression rod 4 away from the connecting plate 3 moves through the side wall of the outer shell 1, and the end of the compression rod 4 on the outside of the outer shell 1 is close to the pressure sensor 7. Finally, a mounting base 11 is installed at the bottom of the outer shell 1. A signal controller 8 electrically connected to the pressure sensor 7 is installed on the outer wall of the mounting base 11. Finally, an alarm 9 electrically connected to the signal controller 8 is installed on the connecting frame 10.

[0024] Specifically: When the gas inside the inner shell 2 is heated, the gas expands. The inner shell 2 deforms due to this expansion, increasing its capacity and maintaining stable internal gas pressure to prevent it from bursting. Simultaneously, the expansion of the outer wall of the inner shell 2 moves the connecting plate 3 and the compression rod 4 located on its outer wall. The moving compression rod 4 compresses the pressure sensor 7, which converts the sensed pressure into an electrical signal. The pressure sensor 7 then outputs a signal to the signal control system. The input port of device 8 is connected, and the alarm 9 is electrically connected to the signal controller 8. The signal controller 8 receives the electrical signal converted by the pressure sensor 7. When the pressure value of the pressure sensor 7 reaches a certain range, the signal controller 8 will control the alarm 9 to sound an alarm, thereby reminding the staff and allowing them to take timely precautions to reduce pressure on the device. When the inner shell 2 expands, it drives the connecting plate 3 to squeeze the compression spring 5. At this time, the deformed compression spring 5 will generate elastic force, which in turn acts on the connecting plate 3, thereby providing a certain restraint and protection for the inner shell 2.

[0025] Embodiment 2

[0026] On the basis of embodiment 1, the scheme in embodiment 1 is further refined in combination with the specific working mode as follows: Figures 1 to 4 As shown in the figure, see the following description in detail:

[0027] As a preferred embodiment, the mounting seat 11 is provided with a heating wire assembly 12, and a power supply assembly is arranged in the mounting seat 11. The power supply assembly can apply current to the heating wire assembly 12. After being powered on, the current passes through the resistance inside the heating wire assembly 12, and the current does work to consume electric energy, thereby generating heat to heat the production saccharin sodium waste gas entering the inner shell 2.

[0028] As a preferred embodiment, a connecting pipe is fixedly connected to the top end of the inner shell 2, a connecting pipe is fixedly arranged at the top end of the outer shell 1, and an air inlet pipe 13 is inserted and arranged at the top end of the connecting pipe. The production saccharin sodium waste gas can be introduced through the air inlet pipe 13, and a sealing ring is arranged at the connection between the two, which can improve the sealing performance of the connection between the connecting pipe and the air inlet pipe 13, avoid leakage of the introduced production saccharin sodium waste gas, and fixedly connect a third connecting flange 17 to the outside of the top end of the connecting pipe. A second connecting flange 16 is arranged on the outer side wall of the air inlet pipe 13 and above the third connecting flange 17, and a first connecting flange 15 is arranged at the top end of the air inlet pipe 13. An air outlet pipe 14 is arranged on the side wall of the inner shell 2. The heated production saccharin sodium waste gas can be discharged through the air outlet pipe 14, and the air outlet pipe 14 is provided with a first connecting flange 15 at one end.

[0029] The working process of the utility model is as follows: first, the production saccharin sodium waste gas can be introduced through the air inlet pipe 13, and then the power supply assembly arranged in the mounting seat 11 applies current to the heating wire assembly 12. After being powered on, the current passes through the resistance inside the heating wire assembly 12, and the current does work to consume electric energy, thereby generating heat to heat the production saccharin sodium waste gas entering the inner shell 2. Then, the heated production saccharin sodium waste gas is discharged through the air outlet pipe 14 for the next catalytic reaction.

[0030] When the gas in the inner shell 2 is heated and expanded, at this time the inner shell 2 will be deformed due to the internal gas heating and expansion, so that the capacity of the inner shell 2 is larger, to maintain the stability of the gas pressure in the inner shell 2, avoid the inner shell 2 easily due to the increase of the internal gas and burst, while the outer side wall of the inner shell 2 expands at the same time, the connecting plate 3 and the extrusion rod 4 arranged on the outer side wall of the connecting plate 3 are moved, the extrusion rod 4 is extruded to the pressure sensor 7, and the pressure sensor 7 converts the pressure into an electric signal, the pressure sensor 7 is connected with the input port of the signal controller 8 through the output signal line, the alarm 9 is electrically connected with the signal controller 8, the electric signal converted by the pressure sensor 7 is received by the signal controller 8, then when the pressure value of the pressure sensor 7 reaches a certain value range, the signal controller 8 controls the alarm 9 to emit a warning sound, so as to remind the staff, the above is the working principle of the heater for treating waste gas of sodium saccharin production.
