Description

Technical Field

[0001] The invention relates to the technical field of waste liquid incineration, in particular to an automated treatment and incineration system and process for salt- and sulfur-containing waste liquid. Background Art

[0002] There are several main ways to incinerate industrial waste liquid, including high temperature oxidation, rotary kiln incineration and fixed bed incineration.

[0003] High temperature oxidation technology is a method of burning waste liquid by high temperature and oxygen. It is usually carried out in a high temperature combustion furnace, so that the waste liquid is heated and oxidized and decomposed under high temperature and high pressure. The advantage of this method is that it has good treatment effect and can treat various types of waste liquid. The disadvantage is high energy consumption and high cost.

[0004] Rotary kiln incineration is a method of treating waste liquid using a rotary kiln reactor. In the rotary kiln, the waste liquid is transferred to a high temperature for drying and combustion decomposition. The advantages of this method are low energy consumption and no secondary pollution. The disadvantage is that the waste liquid needs to be processed into solid matter first, which takes a long time to process.

[0005] Fixed-bed incineration is a conventional waste liquid treatment technology that uses a fixed-bed reactor to directly burn and decompose waste liquid. The waste liquid is sprayed on the fixed-bed reactor and then oxidized and decomposed at high temperature. The advantages of this method are good treatment effect and low cost. It can also treat some difficult-to-treat waste liquids such as particulate matter and halides. The disadvantage is that it is easy to produce secondary pollution, and the purified gas needs further treatment.

[0006] The process flow of waste liquid combustion is divided into pretreatment: Before the waste liquid enters the main treatment system, preliminary pretreatment is usually required. This link mainly includes operations such as screening, sand settling and oil-water separation. Screening is to remove large suspended particles in the waste liquid through a screen, sand settling is to use gravity to precipitate sand and other solid particles with higher density in the waste liquid, and oil-water separation is to separate the grease and water in the waste liquid by standing or centrifuging. Incineration treatment: After pretreatment, the waste liquid is sent to the incineration device for high-temperature thermal oxidation decomposition. The high temperature environment in the incineration device causes the organic matter to oxidize and decompose, and then generate water, carbon dioxide and other harmless substances and discharge them into the atmosphere. During the incineration process, it is necessary to ensure a good atomization effect and supply sufficient combustion air to obtain stable combustion conditions. Waste heat recovery: The high-temperature flue gas generated by incineration is heat exchanged through a waste heat boiler to generate steam. This process not only recovers waste heat, but also further reduces the flue gas temperature for subsequent treatment. ‌Dust removal and blowdown‌: The flue gas after waste heat recovery enters the Venturi dust collector to remove fly ash and dust. The flue gas after dust removal is directly discharged into the atmosphere after meeting environmental protection requirements. The entire flue gas process is in a negative pressure state to ensure safety‌. ‌Auxiliary equipment and systems‌: The incineration equipment also includes auxiliary equipment and systems such as booster pumps, blowers, induced draft fans, boiler dosing systems, boiler blowdown systems, ash and salt transportation / packaging systems, etc. to ensure the smooth progress of the incineration process‌.

[0007] ‌Waste liquid combustion‌Completely decompose pollutants‌: Waste liquid combustion can completely decompose organic matter in waste liquid through high-temperature combustion, converting it into harmless substances such as water and carbon dioxide, thereby reducing the risk of environmental pollution. ‌Reduction and resource utilization‌: The combustion process can achieve waste reduction and reduce the volume of waste liquid. At the same time, part of the heat generated by combustion can be recycled and utilized to achieve resource utilization‌. ‌Treatment of various types of waste liquid‌: The incineration method is suitable for treating high-concentration, toxic and harmful liquid wastes, especially those with high concentrations, complex components, and pollutants that have no recycling value. ‌Efficient treatment‌: The incineration method is an efficient treatment method that can quickly oxidize and decompose organic matter under high temperature conditions, and the COD removal rate can reach more than 99%. ‌Energy saving and material consumption reduction‌: During the incineration process, the thermal efficiency is high, which can save energy and reduce the consumption of high-temperature and corrosion-resistant materials. ‌High safety‌: Modern waste liquid incineration equipment is designed with a complete safety control logic and alarm system to ensure safety during the combustion process‌. ‌Versatility‌: The waste liquid incinerator can not only treat waste liquid, but also treat organic waste gas and a small amount of solid waste, which is very versatile‌.

[0008] For example, the application number 202021047343.0 relates to a high-salt organic waste liquid incineration device, which includes a waste liquid incineration component, a waste heat recovery component and a flue gas purification component connected in sequence. The waste liquid incineration component is used to mix and incinerate the waste solvent and waste liquid input from the waste solvent storage tank and the high-salt organic waste liquid storage tank to harmlessly dispose of the organic pollutants in the waste liquid. The waste gas generated during the treatment process is sent to the waste heat recovery component, and the flue gas purification component is used to purify the waste gas after being cooled by the waste heat recovery component. The high-salt organic waste liquid incineration device proposed in the utility model is simple to operate and has various functions. It can harmlessly incinerate waste solvents and high-salt organic waste liquids and has a good purification effect.

[0009] However, the current automated waste liquid treatment systems mostly have the problem that the time for waste liquid to pass through the atomization suspension zone and the combustion zone is too short, resulting in low efficiency and incomplete combustion of waste liquid in the equipment. The high content of solid particles in the high-temperature flue gas often causes blockage of the heat exchanger and difficulty in cleaning. Blockage due to residue on the inner wall affects the combustion effect, and manual shutdown for slag cleaning is required. The degree of automation is low and the labor intensity is high.

A process for using a salt-containing and sulfur-containing waste liquid automatic treatment and incineration system comprises the following steps: S1, the waste liquid enters the atomizing tube through the waste liquid inlet, is dispersed through the spiral groove plate, and the compressed air enters the internal circulation pipe through the compressed air main pipe and is blown out through the blowing pipe, blowing the pneumatic plate on the dispersion disk to rotate along the mist outlet core pipe, thereby driving the waste water in the stirring chamber to rotate and collide with the waste water on the spiral groove plate, and after forming water mist, it is spirally sprayed out through the spiral spray joint fixedly connected to the mist outlet core pipe; S2, the gas enters the gas distribution pipe through the main gas pipe, and is ignited by the flamethrower at the position of the furnace inner tank where the ignition hole is arranged to form a combustion zone; S3, the high-temperature flue gas enters the primary settling exchange mechanism through the smoke outlet, settles the solid particles in the flue gas, and enters the secondary heat exchange mechanism for residual heat exchange after a heat exchange; S4, the high-temperature flue gas after incineration enters the first-level smoke inlet through the smoke outlet, passes through the bottom of the first-level baffle, the top of the second-level baffle, the bottom of the third-level baffle, and flows out through the first-level smoke outlet at the top of the fourth-level baffle. During the flow, the solid particles in the flue gas are blocked by their own gravity when passing through the inclined smoke baffle on the ceramic baffle and fall to the bottom of the sedimentation box. The high-temperature flue gas exchanges heat with the ceramic baffle, and then exchanges heat with the heat exchange network pipe to achieve a heat exchange. When the ceramic baffle needs to be cleaned or replaced, the side door is opened for replacement; S5, the smoke that has undergone the primary heat exchange enters the secondary smoke inlet through the primary smoke outlet, undergoes secondary heat exchange in the fin-tube heat exchanger, and is discharged through the secondary smoke outlet; S6. When the inner wall of the furnace liner needs to be cleaned, the lifting cylinder is pushed out to push the main gas pipe to drive the flamethrower on the gas distribution pipe away from the furnace liner. When the cleaning is completed, the lifting cylinder is retracted and the flamethrower returns to its original position. S7. Under normal circumstances, the core plate is pulled by the steel wire rope and fixedly arranged on the top of the furnace liner. When the furnace liner needs to be cleaned, the lifting motor is reversed, and the core plate moves downward under its own gravity, and the furnace liner is cleaned by the scraper plate. When the cleaning is completed, the lifting motor rotates forward, driven by the main wheel and the auxiliary support wheel, and restored to the original position by the traction of the steel wire rope; S8. When the set time interval is reached, the plate-loading cylinder is pushed out, driving the collision plate to hit the ash guide hopper, and the collision vibration drives the burnt ash attached to the inner wall to fall through the ash drop port; Compared with the prior art, the present invention has the following beneficial effects: 1. By arranging the atomization suspension zone, combustion zone, and flue gas settling zone vertically from top to bottom, the pressure in the upper cavity of the combustion zone is strong, so that the waste liquid forms a short suspension on the upper side of the combustion zone after atomization, which increases the time for the waste liquid to pass through the atomization suspension zone and the combustion zone, and improves the efficiency and sufficiency of the waste liquid combustion of the equipment. The smoke outlet is set on the lower side, which improves the settling of flue gas fly ash and effectively improves the problem of heat exchanger blockage caused by a large amount of fly ash in the high-temperature flue gas.

[0013] 2. By setting up a cyclone combustion mechanism and combining it with a spiral spray joint, the wastewater is atomized and then passes through the spiral spray joint to form a rotating mist. Multiple groups of cyclone combustion mechanisms are evenly arranged on the outer wall of the furnace shell, spraying fire inward at an oblique angle to form a fire cyclone in the opposite direction of the wastewater atomization. The two collide and combine in the combustion zone, effectively improving the combustion efficiency. Multiple groups of flamethrowers are arranged side by side from top to bottom, which increases the wastewater treatment capacity while improving the waste removal rate in wastewater treatment.

[0014] 3. By setting the main gas pipe, the flamethrower frame lifting seat, the lifting cylinder and the push rod joint, when the inner wall needs to be cleaned, the lifting cylinder pushes the main gas pipe to hide the flamethrower, which is convenient for cleaning the inner wall. When the cleaning is completed, it is pushed out, which improves the overall automation of the equipment and reduces the labor intensity.

[0015] 4. By setting up the waste liquid atomization mechanism, the waste water density is effectively reduced, the high temperature combustion speed is increased, and the processing speed is increased. By setting up the bottom cover plate, supporting steel balls, dispersion disk, pneumatic plate, stirring chamber, and air blowing pipe, the speed of waste water atomization is increased. Compared with the conventional atomization structure, the atomization speed is increased.

[0016] 5. By setting up a two-stage flue gas cooling mechanism, the first-stage sedimentation exchange mechanism is combined with the second-stage heat exchange mechanism. Through the design of the first-stage sedimentation exchange mechanism, not only the effective recovery of the residual heat of the high-temperature flue gas is achieved, but also the design of the first-stage baffle, the second-stage baffle, the third-stage baffle, and the fourth-stage baffle increases the number of high-temperature flue gas circulations in a small space. Combined with the effect of the inclined smoke baffle, the content of solid particles in the high-temperature flue gas is greatly reduced, and the phenomenon of heat exchanger blockage and difficulty in cleaning caused by the high content of solid particles in the high-temperature flue gas is reduced. By adding a second-stage heat exchange mechanism, the recovery rate of flue gas residual heat is improved and energy loss is reduced.

[0017] 6. By setting up ceramic baffles, heat exchange network pipes and sealing plates, the heat exchange network pipes and the flue gas channel are blocked by ceramic baffles, which not only ensures the heat exchange effect, but also effectively reduces the adhesion of solid particles to the heat exchange network pipes, effectively reduces the overall maintenance and cleaning frequency of the equipment, and improves the equipment utilization rate.

[0018] 7. By setting up the inner wall slag cleaning mechanism, the automation level of inner wall slag cleaning is improved, the manual shutdown for slag cleaning is changed, and the service life of the equipment is effectively improved by increasing the frequency of inner wall slag cleaning. The blockage caused by the inner wall residue and the influence on the combustion effect are improved. The avoidance grooves arranged at intervals between the two sets of scraper discs effectively avoid the situation where the effective movement is impossible due to the strong adhesion of the residue.

[0019] 8. By setting up an oscillating dust-falling mechanism, the phenomenon of dust adhering to the inner wall is effectively avoided. The impact plate connected to the plate-mounting cylinder hits the ash guide hopper, making the dust falling smoother and effectively avoiding blockage. BRIEF DESCRIPTION OF THE DRAWINGS
