[0025] Example 2

[0026] On the basis of Example 1, the waste liquid incineration primary circulation system includes a promotion ring plate 16 and multiple adjustment inclined plates 18.

[0027] In the present invention, the water mist in the incinerator 3 rises in the form of a water vapor mass expansion state after being heated by the burner 8. On the way up, it passes through the cone-shaped promotion ring plate 16. At this time, the high-humidity water vapor will hang on the inner wall of the bottom of the promotion ring plate 16 and condense into water droplets and drip back to the bottom of the incinerator 3, thereby realizing a primary cycle and performing a secondary decomposition of the organic matter that is not completely vaporized and decomposed in the water vapor, thereby improving the evaporation and decomposition efficiency of the waste liquid in the incinerator 3. At the same time, the high-temperature expanded steam mass will increase the pressure inside the incinerator 3 and expand and spray out from the exhaust groove 17. Through the present invention, The new type of regulating inclined plate 18 is set in an inclined manner. The power of the steam mass eruption will drive the promotion ring plate 16 to rotate, thereby disturbing and accelerating the water mist in the upper space of the promotion ring plate 16 in the incinerator 3 to promote evaporation. If the water mist just discharged from the atomizing nozzle 11 falls in the state of high-humidity water droplets at an insufficient temperature, it will drip on the promotion ring plate 16 directly below. The centrifugal force of the rotation of the promotion ring plate 16 drives the water droplets to splash onto the inner wall of the incinerator 3 and roll down the wall. In this way, the suspension time of the water droplets in the incinerator 3 is increased, thereby further improving the evaporation and decomposition efficiency of the waste liquid.

[0028] Example 3, based on Example 2, the waste liquid incineration secondary circulation system includes a collecting sieve plate 23, the collecting sieve plate 23 is funnel-shaped, the outer walls of the collecting sieve plate 23 are fixedly connected to the inner wall of the incinerator 3, and the outer wall of the collecting sieve plate 23 is provided with a leakage hole 24.

[0029] The funnel-shaped collecting sieve plate 23 allows the water droplets rolling down the wall to be gathered towards the center again when they roll down to the bottom layer of the incinerator 3, and the droplets are redispersed through the opened leakage holes 24, which facilitates the combustion and heating at the bottom, thereby further improving the evaporation and decomposition efficiency of the waste liquid.

[0030] Example 4. On the basis of Example 2, the pressure monitoring system includes a pressure monitor 19, a gantry 20, a pressure touch platform 21 and a limit spring 22. One side outer wall of the pressure monitor 19 is fixedly connected to the outer wall of one side of the incinerator 3, and the outer walls at both ends of the gantry 20 are fixedly connected to the inner wall of the incinerator 3. The pressure touch platform 21 is fixedly installed in the center position of the outer wall of the gantry 20. The pressure touch platform 21 is located directly above the limit column 12. The limit spring 22 is movably sleeved on the outer wall position of the limit column 12. The bottom outer wall of the limit spring 22 is fixedly connected to the top outer wall of the inner bearing sleeve 14. The top outer wall of the limit spring 22 is movably connected to the bottom outer wall platform of the pressure touch platform 21. The pressure touch platform 21 is connected to the pressure monitor 19 signal, and the pressure monitor 19 is connected to the burner 8 signal.

[0031] In the present invention, if the combustion power is too large, resulting in the excessive pressure of the steam mass below the promoting ring plate 16 exceeding the exhaust power of the exhaust groove 17, the pressure of the steam mass will push the promoting ring plate 16 to move upward along the limiting column 12, leaving a pressure relief space for the steam mass, and using the limiting spring 22, the pushing pressure of the promoting ring plate 16 is transmitted to the pressure touch platform 21 through the limiting spring 22 to perform pressure detection of the limiting spring 22, and the value is analyzed by the pressure monitor 19. When the pressure in the incinerator 3 is too large and the limiting spring 22 is subjected to the threshold pressure, the pressure monitor 19 transmits instructions to control the combustion flue 9 to adjust the combustion power, thereby reducing the steam mass pressure in the incinerator 3.

[0032] The working principle and use process of the present invention are as follows: In the present invention, the waste liquid processed on behalf of the agent in the liquid carrier barrel 1 is transported to the incinerator 3 through the transport pipe 2. The waste liquid is output in a water mist state after passing through the atomizing nozzle 11 in the spraying system, and is sprayed downward from the top of the inner cavity of the incinerator 3. At the same time, the burner 8 is ignited and heated and burned from the bottom of the inner cavity of the incinerator 3 through the combustion flue 9, so that the temperature of the furnace cavity of the incinerator 3 reaches a specified high temperature. The waste liquid in the water mist state sprayed downward will gradually evaporate into water vapor through the high temperature, and enter the SNCR denitration reduction furnace 5 from the exhaust flue 4 through the high-temperature expansion of the gas for flue gas denitration reduction. The solid crystals produced are discharged from the discharge pipe 6 into the collection bin 7. In the present invention, the water mist in the incinerator 3 rises in the form of a water vapor mass expansion state after being heated by the burner 8. On the way up, it passes through the cone-shaped promotion ring plate 16. At this time, the high-humidity water vapor will hang on the inner wall of the bottom of the promotion ring plate 16 and condense into water droplets and drip back to the bottom of the incinerator 3, thereby realizing a primary cycle and performing a secondary decomposition of the organic matter that is not completely vaporized and decomposed in the water vapor, thereby improving the evaporation and decomposition efficiency of the waste liquid in the incinerator 3. At the same time, the high-temperature expanded steam mass will increase the pressure inside the incinerator 3 and expand and spray out from the exhaust groove 17. Through the inclined adjustment inclined plate 18 in the utility model, the power of the steam mass eruption will drive the promotion ring plate 16 to rotate, thereby disturbing and accelerating the incineration. The water mist in the upper space of the promoting ring plate 16 in the incinerator 3 promotes evaporation, and if the water mist just discharged from the atomizing nozzle 11 falls in the state of high-humidity water droplets at an insufficient temperature, it will drip onto the promoting ring plate 16 directly below. The centrifugal force of the promoting ring plate 16 drives the water droplets to splash onto the inner wall of the incinerator 3 and roll down the wall. In this way, the suspension time of the water droplets in the incinerator 3 is increased, thereby further improving the evaporation and decomposition efficiency of the waste liquid. The funnel-shaped collecting sieve plate 23 allows the water droplets that roll down the wall to be re-gathered to the center when they roll down to the bottom layer of the incinerator 3, and the water droplets are redispersed through the leak holes 24, which facilitates the combustion and heating at the bottom, thereby further improving the evaporation of the waste liquid. Decomposition efficiency. In the present invention, if the combustion power is too large, resulting in excessive pressure of the steam mass below the promoting ring plate 16, exceeding the exhaust power of the exhaust groove 17, the pressure of the steam mass will push the promoting ring plate 16 to move upward along the limiting column 12, leaving pressure relief space for the steam mass, and using the limiting spring 22, the pushing pressure of the promoting ring plate 16 is transmitted to the pressure touch platform 21 through the limiting spring 22 to perform pressure detection of the limiting spring 22, and the value is analyzed by the pressure monitor 19. When the pressure in the incinerator 3 is too large and the limiting spring 22 is subjected to the threshold pressure, the pressure monitor 19 transmits instructions to control the combustion flue 9 to adjust the combustion power, thereby reducing the steam mass pressure in the incinerator 3.
