Description

Technical Field

[0001] This invention belongs to the field of chemical waste incineration technology, and is particularly suitable for incineration treatment of high-calorific-value waste liquid containing corrosive elements such as Cl and F. Background Technology

[0002] The chemical industry generates a large amount of high-concentration organic waste liquid during production and manufacturing processes. This waste liquid is often characterized by high toxicity, difficulty in degradation, complex composition, and strong corrosiveness. If it is discharged directly into the environment without effective treatment, it will cause serious harm to the ecosystem and human health.

[0003] Traditional physicochemical methods for treating wastewater suffer from problems such as high cost, inconsistent effectiveness, and secondary pollution emissions. Incineration, on the other hand, is a technology that burns wastewater at high temperatures, converting organic matter into harmless substances. This method not only effectively treats wastewater but also recovers some energy.

[0004] However, these waste liquids have high viscosity, are prone to clogging when heated, and are highly corrosive, posing a serious threat to the stable operation of the equipment. In addition, some waste liquids have high calorific value and are combustible with low or no auxiliary fuel. For such waste liquids, an incineration device is needed to treat these organic waste liquids with these characteristics. Utilizing the high calorific value of self-combusting waste liquids, and through reasonable design, the incineration device can operate stably for extended periods with low auxiliary fuel consumption, ensuring stable combustion and minimizing clogging and corrosion of the incineration equipment. Summary of the Invention

[0005] The technical problem solved by this application is to overcome the shortcomings of the prior art and provide a horizontal offset incineration device and method for treating high-calorific-value and highly corrosive waste liquids, which can fully burn the high-viscosity, high-calorific-value and highly corrosive waste liquids generated in the chemical industry, thereby reducing the operating cost of the incineration equipment and reducing the risk of equipment corrosion.

[0006] The technical solution provided in this application is as follows:

[0007] In a first aspect, a horizontal offset incineration device for treating high-calorific-value and highly corrosive waste liquid is provided, including an incinerator and an offset burner. The incinerator is equipped with a waste gas gun, a steam gun and / or a first waste liquid gun for introducing general waste liquid into the incinerator. One end of the incinerator is provided with an installation hole for installing the offset burner.

[0008] The offset burner includes a housing, and an ignition gun, a secondary gas gun, a waste liquid-gas combination gun, a flame detector, and a second waste liquid gun connected to the housing. The housing is connected to the incinerator, and one end of the housing is inserted into a mounting hole. The connecting pipes of the ignition gun, the secondary gas gun, the waste liquid-gas combination gun, the flame detector, and the second waste liquid gun all extend into the furnace of the incinerator through the mounting hole. The secondary gas gun is used to introduce gas into the furnace, the waste liquid-gas combination gun is used to introduce gas and high-calorific-value, highly corrosive waste liquid into the furnace, the ignition gun is used to ignite the gas, the flame detector is used to detect whether the gas from the secondary gas gun has been ignited, and the second waste liquid gun is used to introduce high-calorific-value, highly corrosive waste liquid into the furnace.

[0009] The shell is provided with an inner cavity and an air inlet. The air inlet is connected to the inner cavity. The shell is connected to an air duct. One end of the air duct is connected to the inner cavity and the other end is connected to the furnace of the incinerator. The secondary gas gun and the waste liquid gas combination gun are both located inside the air duct, and flame stabilizers are provided between the secondary gas gun, the waste liquid gas combination gun and the air duct.

[0010] The end of the air duct that connects to the inner cavity of the shell is open.

[0011] The secondary gas gun is positioned below the horizontal axis of the incinerator, while the waste liquid gas combination gun and the second waste liquid gun are positioned above the horizontal axis of the furnace body.

[0012] At least two waste liquid gas combination guns are provided, located on both sides of the secondary gas gun, and the second waste liquid gun is arranged between the waste liquid gas combination guns.

[0013] The waste liquid-gas combination gun and the second waste liquid gun are distributed in the same circumference with the axis of the secondary gas gun as the axis, and the circumference of their distribution is the first circumference; the flame detector and the ignition gun are distributed in the same circumference with the axis of the secondary gas gun as the axis, and the circumference of their distribution is the second circumference; the first waste liquid gun, the waste gas gun, and the steam gun are all arranged on the incinerator and distributed in the same circumference with the axis of the incinerator as the axis, and the circumference of their distribution is the third circumference; the radius of the third circumference > the radius of the second circumference > the radius of the first circumference.

[0014] The waste liquid-gas combination gun includes a main waste liquid gun and a main gas gun. The main gas gun includes an inner gun barrel, an outer gun barrel, a nozzle, and a gas inlet. The outer gun barrel is sleeved outside the inner gun barrel, and one end of the outer gun barrel and the inner gun barrel are fixedly and sealed together. The nozzle is connected between the other end of the outer gun barrel and the inner gun barrel. A gas inlet is provided on the outer gun barrel, and the gas enters the space between the outer gun barrel and the inner gun barrel through the gas inlet. The main waste liquid gun is inserted into the inner gun barrel and connected to the inner gun barrel through a flange. The main waste liquid gun is used to introduce high-calorific-value, highly corrosive waste liquid into the incinerator.

[0015] Refractory castable is poured into the mounting hole to form a refractory zone; a small combustion chamber for stable combustion of the accompanying gas is opened on the side of the refractory zone facing the furnace, and the end of the secondary gas gun is located in the small combustion chamber.

[0016] The incinerator includes a front section and a rear section, which are detachably connected by a flange.

[0017] Secondly, a horizontal offset incineration method for treating high-calorific-value, highly corrosive waste liquid is provided, comprising incinerating using any of the aforementioned horizontal offset incineration devices for treating high-calorific-value, highly corrosive waste liquid, including:

[0018] S1: Start the ignition gun. After the flame detector detects the flame signal of the ignition gun, the secondary gas gun is supplied with gas to the maximum flow rate. Then, one of the waste liquid gas combination guns is supplied with gas until the maximum flow rate is reached. Then, the other waste liquid gas combination gun is supplied with gas until the temperature meets the feeding requirements.

[0019] S2: Turn on the second waste liquid gun, put in high calorific value and highly corrosive waste liquid, and gradually shut off the gas in one of the waste liquid gas combination guns. At this time, the secondary gas gun and one waste liquid gas combination gun spray gas, and the single second waste liquid gun sprays high calorific value and highly corrosive waste liquid.

[0020] S3: Cool one of the waste liquid gas combination guns and shut it off. After the nozzle temperature of the waste liquid gas combination gun cools down, introduce high-calorific-value, highly corrosive waste liquid and gradually shut off the gas supply to the other waste liquid gas combination gun. At this time, the secondary gas gun sprays gas, and the first and second waste liquid guns spray high-calorific-value, highly corrosive waste liquid.

[0021] S4: Cool the other waste liquid gas combination gun. After it cools down, add high-calorific-value, highly corrosive waste liquid. At this time, the secondary gas gun sprays co-burning gas, and the two waste liquid gas combination guns and the second waste liquid gun spray high-calorific-value, highly corrosive waste liquid. At this point, the operation mode of the offset burner has been switched.

[0022] S5: After the offset burner is running stably, turn on the material gun, exhaust gas gun and steam gun on the incinerator to feed materials into the incinerator, and adjust the flue gas temperature at the furnace outlet by adjusting the air intake of the incinerator.

[0023] In summary, this application includes at least the following beneficial technical effects:

[0024] The advantages of this invention compared to existing technologies are as follows: This invention provides a horizontal offset incineration device for treating high-calorific-value, highly corrosive waste liquid, comprising a burner and an incinerator. The burner utilizes the high-calorific-value waste liquid and a small amount of fuel gas to provide heat. Through its offset structural design, it not only treats the high-calorific-value, highly corrosive waste liquid but also provides a stable heat source for the combustion of waste gas and waste liquid (i.e., general waste liquid and waste gas on the furnace body) in the incinerator, effectively reducing the operating costs of the incineration equipment. A special operating method cleverly solves the problem of easy blockage of waste liquid due to heat during the incinerator's start-up process. The detachable design of the furnace body provides design margins for high-risk locations on the incineration equipment that may be damaged, facilitating later maintenance. The arrangement of materials (waste liquid, waste gas, and steam) on the conical surface accelerates the thermal decomposition time of the waste liquid, promoting complete combustion and reducing the risk of corrosion caused by waste liquid spraying onto the wall surface. In incineration equipment, whether it is the burner or the incinerator, all waste liquid is arranged above the horizontal axis. The gas gun at the bottom of the incineration equipment provides a stable gas flame. Even if the waste liquid at the top of the equipment is not completely atomized, the larger droplets will still fall onto the flame generated by the gas gun and be decomposed by heat, ensuring that the waste liquid will not drip onto the wall and corrode the furnace wall. Similarly, the waste liquid gun on the conical surface of the furnace body is also located above the horizontal axis. Droplets generated by incomplete atomization will fall onto the flame generated by the burner and be decomposed by heat.

[0025] High-calorific-value waste liquid can be sprayed onto the burner, while low-calorific-value waste liquid can be sprayed onto the furnace body. Only a small amount of co-firing gas needs to be introduced into the burner to ensure complete combustion of the waste liquid, thereby reducing the operating cost of the incineration equipment and minimizing the risk of equipment corrosion.

[0032] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0033] This application discloses a horizontal offset incinerator for treating high-calorific-value, highly corrosive waste liquid, including a horizontal incinerator suitable for treating such waste liquid, such as... Figure 1 As shown, the incineration apparatus includes an offset burner and an incinerator. The offset burner is connected to one end of the incinerator and is used to ignite the fuel gas and / or waste liquid entering the incinerator.

[0034] On the burner, the high-calorific-value, highly corrosive waste liquid to be treated is positioned above the horizontal axis of the burner, while a small amount of accompanying combustion gas is positioned below the horizontal axis of the burner. The purpose is to create a stable ignition source below the burner, ensuring that while the high-calorific-value, highly corrosive waste liquid is ignited, large droplets generated during atomization can still drip to the ignition source for combustion, rather than dripping directly onto the inner wall of the burner and corroding it. Two waste liquid-gas combination guns are used for furnace heating and feeding. Because the waste liquid is prone to clogging when heated, immediate feeding after heating carries the risk of clogging the spray guns. Therefore, a secondary waste liquid gun is separately designed on the burner, which can be used for immediate feeding after heating is complete. The primary waste liquid gun in the waste liquid-gas combination gun requires cooling before feeding.

[0035] like Figure 1 As shown, the incinerator includes a front section 19 and a rear section 20. The front section 19 is equipped with a first waste liquid gun 10, a waste gas gun 17, and a steam gun 16. The inner walls of both the front section 19 and the rear section 20 are provided with a refractory layer 12. The furnace body is equipped with a manhole 13, a thermocouple 14, and a large sight glass 15.

[0036] The front section 19 of the furnace body is frustum-shaped, with an offset burner arranged on its small circular surface. The large circular surface of the front section 19 is connected to a first connecting flange, and the ends of the front section 19 and the rear section 20 of the furnace body, directly opposite each other, are connected to a second connecting flange. The connection between the first and second connecting flanges allows for a detachable connection between the front and rear sections of the furnace body, facilitating disassembly and maintenance of the front section 19. The offset burner is used to ignite the gas and / or waste liquid within the incinerator, and to introduce gas into the incinerator.

[0037] The first waste liquid gun 10, waste gas gun 17, steam gun 16, and other guns that may need to be arranged on the furnace body are located at the frustum-shaped conical surface of the front section 19 of the furnace body. The first waste liquid gun 10 is used to introduce general waste liquid into the furnace body. High-calorific-value, highly corrosive waste liquid refers to waste liquid that can be burned under low or even no co-firing conditions. General waste liquid refers to waste liquid other than high-calorific-value, highly corrosive waste liquid. The material entering at this location is close to the flame generated by the burner, which is conducive to the rapid heating and decomposition of the material.

[0038] All the first waste liquid guns 10, waste gas guns 17, and steam guns 16 on the incinerators are arranged above the horizontal axis of the incinerator's furnace. Figure 2 As shown, their quantity and location can vary depending on different design conditions; for example, [the following text is incomplete and requires further context]. Figure 2 The 17 intermediate exhaust gas guns were replaced with two, which can be symmetrically arranged on the central axis. Both guns point towards the furnace axis at an angle between 10° and 40°.

[0039] All the first waste liquid guns 10, waste gas guns 17 and steam guns 16 on the incinerator are arranged above the horizontal axis of the furnace body, and are symmetrically arranged on both sides of the incinerator body according to the type and quantity of material guns.

[0040] Manhole 13 is used for personnel to enter and exit the equipment for maintenance and other operations. Thermocouple 14 is used to detect the temperature inside the furnace. Large sight glass 15 is arranged at the tail end of the incinerator to observe the combustion situation inside the entire incinerator.

[0041] like Figure 2 and Figure 3 As shown, the offset burner includes a housing 3, and connected to the housing 3 are an ignition gun 1, a secondary gas gun 2, at least two waste liquid-gas combination guns 4, two flame detectors 5, and a second waste liquid gun 18. The waste liquid-gas combination gun 4 is used to introduce gas and high-calorific-value, highly corrosive waste liquid into the furnace. The ignition gun 1 is used to ignite the gas. The flame detectors 5 are used to detect whether the gas in the secondary gas gun 2 is ignited. The second waste liquid gun 18 is used to introduce high-calorific-value, highly corrosive waste liquid into the furnace.

[0042] A mounting hole is provided on the small circular surface of the front section 19 of the furnace body. One end of the shell 3 is inserted into the mounting hole, and the shell 3 is connected to the front section 19 of the furnace body via a flange. The shell 3, the front section of the furnace body, and the rear section of the furnace body are coaxial. Refractory castable is applied into the mounting hole to obtain the refractory zone 6.

[0043] Both the secondary gas gun 2 and the waste liquid gas combination gun 4 are connected to the shell 3 and pass through the refractory zone 6 to enter the furnace chamber at the front of the furnace body. Each of the secondary gas gun 2, the second waste liquid gun 18, and each waste liquid gas combination gun 4 is externally fitted with an air duct 9. One end of the air duct 9 is connected to the shell, and the other end passes through the refractory zone 6, thus connecting the air duct 9 to the inner cavity of the shell 3 and the furnace chamber at the front of the furnace body. The end of the air duct 9 connecting to the inner cavity of the shell 3 is open. The shell 3 is provided with an air inlet for supplying air into the inner cavity of the shell. The open shape of the air duct 9 has a guiding function, facilitating air entry into the air duct and reducing resistance. The airflow of each air duct can be distributed according to the diameter of each air duct 9.

[0044] The ignition gun 1, the flame detector 5, and the second waste liquid gun 18 also pass through the refractory zone 6 and enter the furnace chamber at the front of the furnace body. The flame detector is equipped with a connecting pipe for installation. The connecting pipe for installing the flame detector is inserted into the furnace chamber. The flame detector is a monitoring device similar to a light signal and does not need to be inserted into the furnace chamber.

[0045] Each of the secondary gas gun 2, the second waste liquid gun 18, and each waste liquid gas combination gun 4 is equipped with a flame stabilizer between itself and the inner wall of the outer air duct 9. The flame stabilizer includes a preset number of swirl vanes 8, which are connected between the waste liquid gas combination gun 4 and the inner wall of the air duct. They are used to make the air flow in a rotating manner after passing through the swirl vanes 8, so that the fuel can burn stably.

[0046] A small combustion chamber 7 is provided on the side of the refractory zone 6 facing the furnace to ensure stable combustion of the auxiliary combustion gas. The end of the secondary gas gun 2 is located inside the small combustion chamber 7. The diameter of the air duct 9 on the outside of the secondary gas gun 2 decreases at the end facing the furnace to form a throat. The air intake can be adjusted by the size of the throat. The small combustion chamber 7 is located behind the throat to ensure stable combustion of the gas.

[0047] like Figure 4 As shown, the waste liquid-gas combination gun 4 includes a main waste liquid gun 41 and a main gas gun 42. The main gas gun 42 includes an inner gun barrel 421, an outer gun barrel 422, and a nozzle 423. The outer gun barrel 422 is sleeved outside the inner gun barrel 421 and is connected to the air duct, with a flow stabilizer connected between them. One end of the outer gun barrel 422 and the inner gun barrel 421 are fixedly and sealed together, while the other end of the outer gun barrel 422 and the inner gun barrel 421 is connected to the nozzle 423. A gas inlet is provided on the outer gun barrel 422, through which gas enters the space between the outer gun barrel 422 and the inner gun barrel 421 and is finally ejected from the nozzle 423. The main waste liquid gun 41 is inserted into the inner gun barrel 421 and connected to it via a flange. The main waste liquid gun 41 is used to introduce waste liquid into the incinerator.

[0048] A single secondary gas torch 2 is positioned below the horizontal axis of the furnace body, two waste liquid gas combination torches 4 are located on either side of the secondary gas torch 2, and a single second waste liquid torch 18 is positioned between the two waste liquid gas combination torches 4. Furthermore, the two waste liquid gas combination torches 4 and the single second waste liquid torch 18 are positioned above the horizontal axis of the furnace body.

[0049] The waste liquid-gas combination gun 4 and the second waste liquid gun 18 are arranged in the same circumference with the axis of the secondary gas gun 2 as the axis, and the circumference of their arrangement is called the first circumference. The flame detector 5 and the ignition gun 1 are arranged in the same circumference with the axis of the secondary gas gun 2 as the axis, and the circumference of their arrangement is called the second circumference. The first waste liquid gun 10, the waste gas gun 17, and the steam gun 16 are all arranged on the incinerator and are arranged in the same circumference with the axis of the incinerator as the axis, and the circumference of their arrangement is called the third circumference. The radius of the third circumference > the radius of the second circumference > the radius of the first circumference.

[0050] Ignition gun 1 is equipped with an auxiliary flame detector. After ignition, ignition gun 1 can be used as a flame detector, simultaneously aligned with the end of the single secondary gas gun 2 along with two other flame detectors 5, to monitor the flame of ignition gun 1 and the flame of the single secondary gas gun 2 after ignition. That is, it is used to detect the presence or absence of a flame during the ignition phase and to detect whether the gas gun is operating normally during normal operation, ensuring the normal operation of the equipment. Ignition gun 1 and flame detectors 5 are positioned above the horizontal axis of secondary gas gun 2, with their nozzles facing secondary gas gun 2, to ignite the gas in secondary gas gun 2 and monitor its flame.

[0051] The secondary gas gun 2 provides stable combustion gas, while the gas from the two waste liquid gas combination guns 4 is used for furnace heating and incinerating high-calorific-value waste liquid containing F and Cl elements. The waste liquid and gas in the waste liquid gas combination guns cannot operate simultaneously. The second waste liquid gun 18 can operate independently.

[0052] Because the waste liquid on the offset burner is prone to clogging the nozzle when heated, the specific operating steps of the entire equipment are as follows:

[0053] 1) Start the ignition gun 1 on the bias burner. After the flame detector 5 detects the flame signal of the ignition gun 1, the secondary gas gun 2 is supplied with gas to the maximum flow rate. Then, one of the waste liquid gas combination guns 4 is supplied with gas until the maximum flow rate is reached. Then, the other waste liquid gas combination gun 4 is supplied with gas until the temperature meets the feeding requirements.

[0054] 2) Turn on the second waste liquid gun 18, put in high calorific value and highly corrosive waste liquid, and gradually shut off the gas in one of the waste liquid gas combination guns 4. At this time, the secondary gas gun 2 and one waste liquid gas combination gun 4 spray gas, and the single second waste liquid gun 18 sprays high calorific value and highly corrosive waste liquid.

[0055] 3) Use atomizing medium (compressed air) to purge one of the closed waste liquid gas combination guns 4 to cool it down (to prevent the waste liquid from being heated and blocking the waste liquid gas combination gun 4 in a high-temperature environment). After the gun head temperature has cooled down, introduce high-calorific-value, highly corrosive waste liquid and gradually close the other waste liquid gas combination gun until it no longer supplies gas. At this time, the secondary gas gun 2 sprays gas, and one waste liquid gas combination gun 4 and a single second waste liquid gun 18 spray high-calorific-value, highly corrosive waste liquid.

[0056] 4) Similarly, cool the other waste liquid gas combination gun 4. After it cools down, put in high-calorific-value, highly corrosive waste liquid. At this time, the secondary gas gun 2 sprays co-burning gas, and the two waste liquid gas combination guns 4 and the single second waste liquid gun 18 spray high-calorific-value, highly corrosive waste liquid. At this point, the operation mode of the offset burner has been switched.

[0057] 5) After the offset burner is running stably, turn on the material guns on the incinerator - the first waste liquid gun 10, the steam gun 16, and the waste gas gun 17, and feed the material into the incinerator. Adjust the flue gas temperature at the furnace outlet by adjusting the air intake of the incinerator.

Those skilled in the art will understand that various equivalent substitutions, modifications, or improvements can be made to the technical solutions and implementation methods of the present application without departing from the spirit and scope of the present application, and all such modifications and improvements fall within the scope of the present application.
