DETAILED DESCRIPTION
[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:
[0016] like Figure 1 As shown, the pharmaceutical production three waste incineration disposal device is composed of a rotary kiln 1, a secondary combustion chamber 2, a waste heat boiler 3, a flue gas treatment device, and related pipelines, instruments, etc.
[0017] The rotary kiln 1 is used for the incineration of three types of waste gases. A feed chamber 4 is installed at one end of the rotary kiln 1, and the feed chamber 4 is used for preliminary mixing and heating of materials. The feed chamber 4 is connected to the inner cavity of the rotary kiln 1, and a solid waste feeding device is installed on one side of the feed chamber 4. The solid waste feeding device includes a bucket elevator 5, a high-level silo 6, a hydraulic push device 7 and a hydraulic station 8. The high-level silo 6 is supported above the feed chamber 4, and the top end of the bucket elevator 5 corresponds to the top opening of the feed chamber 4. The bucket elevator 5 is used to lift the solid material and tip the bucket at the top to add the solid material into the high-level silo 6.
[0018] Two upper and lower gate valves 9 are installed in the high-level silo 6, and the gate valves 9 are controlled by the hydraulic station 8. The quantitative discharge of materials can be achieved by opening and closing the two gate valves 9 at intervals. When the gate valve at the bottom is opened, the materials between the two gate valves fall into the hydraulic pushing device 7 below them.
[0019] The hydraulic pushing device 7 includes a hydraulic pushing head 71 and a material guiding cavity 72. The feed port of the material guiding cavity 72 is located directly below the discharge port at the bottom of the high-level silo 6. The material guiding cavity 72 passes through the feed cavity 4 and extends into the rotary kiln 1. Through the control of the hydraulic station 8, the hydraulic pushing head 71 pushes the material falling into the material guiding cavity 72 into the rotary kiln 1 for incineration.
[0020] A waste liquid feeding device is fixedly installed on the side wall of the upper part of the feed chamber 4, and the waste liquid feeding device includes an atomizing nozzle 10, a high-pressure air pipe 11 and a waste liquid pipe 12. The atomizing nozzle 10 extends into the feed chamber 4 from the top of the feed chamber 4. The high-pressure air in the high-pressure air pipe 11 and the waste liquid in the waste liquid pipe 12 are atomized by the atomizing nozzle 10 and then sprayed toward the inner cavity of the rotary kiln 1. The atomized waste water can be quickly and fully burned.
[0021] An air intake pipe is also provided on the side of the upper part of the feed chamber 4, and the air intake pipe is connected to a waste gas feeding device, which is a waste gas fan 13. The input end of the waste gas fan 13 is connected to the tail gas pipe. The waste gas fan 13 sends the waste gas generated in the workshop into the feed chamber 4 for incineration treatment.
[0022] A combustion device is installed in the middle and lower part of the feed chamber 4. The combustion device mainly includes a combustion fan 14 and a combustion gun 15. The combustion gun 15 is inserted into the feed chamber 4 and faces the inner cavity of the rotary kiln 1. The combustion fan 14 sends the natural gas in the natural gas pipeline into the combustion gun 15 and sprays flames into the rotary kiln 1. A cooling fan 26 is connected to the end of the rotary kiln to cool the ash.
[0023] The three forms of materials are dried, pyrolyzed or burned at high temperature in the rotary kiln 1 and completely burned as the kiln body rotates. The residue after combustion falls from the end of the rotary kiln into the secondary combustion chamber 2, and the smoke after combustion continues to move upward in the secondary combustion chamber 2.
[0024] A secondary combustion device is installed in the middle of the secondary combustion chamber 2. The secondary combustion device includes a secondary combustion gun 16 and a secondary combustion fan 17. The secondary combustion fan 17 provides natural gas to the secondary combustion gun 16. A secondary air inlet device is installed above the secondary combustion device. The secondary air inlet device is a secondary fan 18. The secondary fan 18 sends external air to assist combustion. The secondary combustion device continues to burn the combustibles in the flue gas. A smoke exhaust port is provided at the top of the secondary combustion chamber 2, and the smoke exhaust port is connected to the waste heat boiler through a pipeline.
[0025] The slag outlet at the bottom of the secondary combustion chamber 2 is equipped with a star-shaped discharger 19. The ash dropped from the rotary kiln 1 and the ash after secondary combustion fall into the star-shaped discharger 19. The star-shaped discharger 19 is provided with a cooling jacket, and the cooling jacket is connected to a circulating cooling system to achieve high-temperature protection of the star-shaped discharger 19 and cooling of the ash. The cooling system includes a cooling water tank 20 and a cooling water pump 21. The cooling water pump 21 circulates the water in the cooling water tank 20 in the cooling jacket. A scraper ash discharger 22 is installed at the discharge outlet at the bottom of the star-shaped discharger 19. The cooled ash is taken out and collected by the scraper ash discharger 22, waiting for further harmless treatment.
[0026] The lower part of the waste heat boiler 3 is a smoke inlet chamber 31, and the upper part is a heat exchange chamber 32. The smoke inlet chamber 31 is connected to the secondary combustion chamber 2. An ammonia spray gun 23 is installed on the inner wall of the smoke inlet chamber 31, and the sulfides in the flue gas are preliminarily treated with ammonia. An ash hopper 24 is installed at the bottom of the smoke inlet chamber 31 for collecting ash. The smoke enters the heat exchange chamber 32 from the smoke inlet chamber 31. The hot water in the water tank in the heat exchange chamber 32 absorbs the heat of the smoke and generates steam. The top of the heat exchange chamber is connected to a steam buffer tank 25 through a pipeline. The steam buffer tank 25 is connected to the steam network to achieve energy recovery.
