Reinforcing ribs 3-5 are welded on the side wall and the bottom wall of the reaction kettle 3 in the example. The reinforcing ribs 3-5 in the example are angle steels which are easy to obtain, and the purpose of reinforcing the structure of the reaction kettle 3 is achieved by welding the angle steels on the reaction kettle 3.

In this example, the welds of adjacent steel plates, adjacent breaker plates 3-2-1 and adjacent screens 3-3-1 are welded together by adaptors 3-6. Preferably, the adaptors 3-6 of the present example are bent gussets.

The adaptor 3-6 of the present example is a unitary structure, i.e. a common adaptor for the bottom shell 3-1, the middle shell 3-2 and the top shell 3-3. In other embodiments of the present invention, for the convenience of welding, the adaptor 3-6 may also be a split structure, and the bottom shell 3-1, the middle shell 3-2 and the upper shell 3-3 have respective adaptors or two adjacent shells share the same adaptor.

The mounting port 5-2-3 is used for replacing and cleaning the spray nozzle 5-6, and in order to facilitate processing and division of functions, the mounting port 5-2-3 and the circulating water inlet 5-2-1 are respectively arranged at two sides of the smoke exhaust pipe 5-2; referring to fig. 1 and 4, in the present embodiment, each smoke exhaust pipe 5-2 is provided with a tail gas inlet 5-2-3, and the tail gas inlet 5-2-2 and the installation port 5-2-3 are arranged on the same side of the smoke exhaust pipe 5-2 and below the installation port 5-2-3. When the exhaust gas treatment device of the present example is in operation, the sealing cover 5-7 is to be sealingly mounted on the mounting opening 5-2-3 to prevent exhaust gas from leaking through the mounting opening 5-2-3, and sealing is accomplished between the sealing cover 5-7 and the mounting opening 5-2-3 by mounting a sealing gasket or a sealing ring.

In this example, the lower end of the water tank 5-1 is also provided with a waste water discharge port 5-1-2. After the tail gas is treated by adopting the water circulation in the water tank 5-1 for a period of time, the water quality of the water tank 5-1 can influence the treatment effect of the tail gas, and at the moment, the water in the water tank 5-1 can be discharged through the wastewater discharge port 5-1-2.

In the example, the lower end of the water tank 5-1 is also provided with a lower liquid level meter interface 5-1-3, and the upper end of the water tank 5-1 is provided with an upper liquid level meter interface 5-1-4 and a water replenishing port 5-1-5. An upper liquid level meter interface 5-1-4 and a lower liquid level meter interface 5-1-3 which are arranged at the upper end and the lower end of the water tank 5-1 are respectively used for connecting an upper liquid level meter and a lower liquid level meter, and the upper liquid level meter and the lower liquid level meter are used for monitoring the water quantity in the water tank 5-1. The lower liquid level meter can be connected with the alarm element, when the lower liquid level meter detects that the water level of the water tank 5-1 is lower than a certain value, a signal is sent to the alarm element, and the alarm element works to remind related personnel of adding water into the water tank through the water replenishing port 5-1-5; the lower liquid level meter can be connected with a control element, the control element is connected with a water adding pump, the water adding pump is connected with the water replenishing port 5-1-5 through a water pipe, when the lower liquid level meter detects that the water level of the water tank 5-1 is lower than a certain value, a signal is sent to the control element, the control element controls the water adding pump to work, and water is added into the water tank 5-1 through the water replenishing port 5-1-5.

In this example, the upper end of the water tank 5-1 is provided with a medicine feeding port 5-1-6, and a protective cover 5-8 is arranged on the medicine feeding port 5-1-6. In order to enhance the purification effect of the tail gas, some medicaments capable of neutralizing harmful substances in the tail gas, such as NaOH, are added into the water tank 5-1 through the medicament adding port 5-1-6; after the chemicals are not required to be added or are added, a protective cover 5-8 is arranged on the chemical adding port 5-1-6 to prevent other impurities such as dust from falling into the water tank 5-1 to affect the flowability of water and the normal work of equipment in a water circulation system.

In this example, the bottom of the water tank 5-1 is further provided with a support frame 5-9 for supporting the exhaust gas treatment device 5. Referring to fig. 7-8, the bottom of the water tank 5-1 of the present example is provided with two support frames 5-9 for stably supporting the whole exhaust gas treatment device 5.

The waste carbonization and pyrolysis system of the example is also provided with an exhaust fan 9 connected with the tail gas treatment device 5, so that the tail gas can be discharged after being treated by the tail gas treatment device 5 at an excessive speed.

It should be noted that, one end of the carbonization furnace 1 for transferring the reaction kettle 3 in the present example is provided with a sealing door 1-2 for sealing the carbonization furnace 1, and the outside of the sealing door 1-2 is provided with a switch door 1-3; a furnace body base 1-4 for supporting the carbonization furnace 1 is arranged at the bottom of the carbonization furnace 1; each area for placing the reaction kettle 3 on the support frame 2 in the carbonization furnace 1 is provided with a radiant tube 1-1 for heating the reaction kettle 3, and in order to meet the combustion inside the radiant tube 1-1, the garbage carbonization pyrolysis system is also provided with an air blower 10 for supplementing air to the radiant tube 1-1 and ensuring the combustion of the radiant tube 1-1; referring to fig. 2, the radiant tube 1-1 is spaced a distance from the blower 10 to facilitate replacement of the radiant tube 1-1. Referring to fig. 2-3, a guard rail 7 and a ladder 8 are arranged above the garbage carbonization and pyrolysis system, so that the whole system can be conveniently installed and maintained.
