Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a coking VOCs-producing dry quenching coke incineration system. Background Art

[0002] VOCs are also called volatile organic compounds. During the process of dry quenching coke incineration in a coking plant, a large amount of VOCs will be generated. Since VOCs contain harmful substances, direct emission will seriously pollute the environment. Therefore, they need to be treated before emission. For example, in the patent application number "CN202211527946.4" and the name of "VOCs waste gas entering dry quenching coke incineration device and method thereof", the VOCs waste gas entering dry quenching coke incineration device also includes a steam generator, and the high-temperature flue gas outlet of the dry quenching coke is connected to the steam generator to drive the steam generator to generate electricity, effectively utilize high-temperature steam, and reduce unnecessary emissions. The embodiment of the present application also provides a VOCs waste gas entering dry quenching coke incineration method In this method, the VOCs waste gas is directly introduced into the reaction chamber of the acid washing spray tower. After the acid washing treatment, the alkaline gas in the VOCs waste gas is purified, and the purified gas is discharged from the top of the acid washing spray tower. The discharged purified gas enters the alkali washing spray tower from the bottom pipeline, and the acid washing substances in the gas are washed and purified by an alkaline solution, and finally discharged from the top of the alkali washing spray tower. The gas after acid washing and alkali washing enters the water washing spray tower, and the water-soluble substances in the gas, such as ammonia, are washed down by the water washing spray tower. The separated ammonia liquid can be recycled and processed, and can be recycled, which effectively reduces the ammonia content again to ensure that the subsequent combustion can be sufficient. However, the above structure still has the following problems in actual use:

[0003] The above structure realizes the treatment of VOCs through a water washing spray tower and an alkali washing spray tower, but toxic substances will be attached to the waste liquid after spraying, so it cannot be discharged directly, and the existing spray tower cannot collect the waste liquid well. At the same time, it is difficult to completely remove the harmful substances in VOCs only by spraying, so the treatment effect is limited.

[0004] Therefore, we proposed that the VOCs produced by coking can be introduced into the dry quenching incineration system to solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a coking VOCs dry quenching incineration system to solve the problem raised by the above-mentioned background technology that toxic substances will be attached to the waste liquid after spraying in the current market, so it cannot be discharged directly, and the existing spray tower cannot collect the waste liquid well. At the same time, it is difficult to completely remove the harmful substances in VOCs only by spraying, so the treatment effect is limited.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a coking VOCs-producing dry quenching coke incineration system, comprising an incinerator, the right side of which is connected to a connecting pipe, and the other end of which is connected to a spray tower;

[0007] It also includes: a fan is fixedly installed on the outer side of the connecting pipe, and a diverter is fixedly installed inside the spray tower, and the diverter is arranged in a staggered structure, and a nozzle is fixed on the lower end surface of the diverter, and the right end surface of the diverter is connected to one end of the hose;

[0008] The lower end surface of the spray tower is connected and fixed with a sewage pipe, and the lower end of the sewage pipe is fixed to the upper surface of the waste liquid collection box, and the waste liquid collection box is placed on the surface of the horizontal plate between the supporting legs;

[0009] An activated carbon plate is fixedly installed above the internal diverter of the spray tower, and a condenser is fixedly installed inside the spray tower above the activated carbon plate.

[0010] Preferably, the outer end of the hose passes through the outer side of the spray tower and is connected to an external water pump, and the external water pump is connected to a water source.

[0011] Preferably, a gas monitor is fixedly mounted on the inner wall of the upper end surface of the spray tower, and an exhaust pipe is connected and fixed to the upper end surface of the spray tower.

[0012] Preferably, an explosion-proof cover is provided above the incinerator, and a sealing strip is bonded and fixed to the lower end surface of the explosion-proof cover, and the sealing strip fits with the incinerator.

[0013] Preferably, plug-in plates are welded and fixed on both sides of the incinerator, and plug-in blocks are plugged into the inside of the plug-in plates, and the upper ends of the plug-in blocks are welded and fixed to the explosion-proof cover.

[0014] Preferably, a clamping rod is clamped inside the outer side of the plug-in block, and the clamping rod is elastically slidably connected to the plug-in board via a return spring, and two ends of the return spring are respectively fixed to the plug-in board and the clamping rod.

[0015] Preferably, the front side of the incinerator is provided with an air blast port, and the rear end of the air blast port penetrates to the inner bottom end of the incinerator, and an incineration plate is fixedly provided inside the incinerator, and through holes are opened on the surface of the incineration plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the VOCs produced by coking are introduced into the dry quenching coke incineration system, which not only realizes the collection of waste liquid, thereby facilitating the centralized treatment of waste liquid by workers, but also further reduces the harmful substances in the waste gas, improves the purification effect, and monitors the VOCs waste gas at the same time, so as to avoid the harmful substances in the VOCs waste gas from being discharged before being treated, thereby avoiding the VOCs waste gas from polluting the environment, and finally the VOCs waste gas that meets the standards will be discharged through the exhaust pipe, thereby achieving the effect of treating the VOCs waste gas, and its specific contents are as follows:

[0017] (1) By starting the external water pump, the water pump sends water into the diverter through the hose, and then sprays it out in the diverter nozzle through the diverter, thereby achieving the effect of spraying the VOCs waste gas. The waste liquid after spraying will fall to the bottom of the spray tower by gravity. Through the setting of the sewage pipe, the waste liquid can be sent to the waste liquid collection box through the sewage pipe, thereby realizing the collection of the waste liquid, so as to facilitate the centralized treatment of the waste liquid by workers;

[0018] Furthermore, by setting up the activated carbon plate, the harmful substances in the VOCs exhaust gas can be adsorbed and evolved, thereby further reducing the harmful substances in the exhaust gas and improving the purification effect;

[0019] Furthermore, through the setting of gas monitors, VOCs waste gas can be monitored to prevent harmful substances in VOCs waste gas from being discharged without being treated, thereby preventing VOCs waste gas from polluting the environment. Finally, the VOCs waste gas that meets the standards will be discharged through the exhaust pipe, thereby achieving the effect of treating VOCs waste gas.

[0020] (2) When the dry quenched coke in the incinerator is completed and new dry quenched coke needs to be added, the clamping rod is pulled to separate the inner end of the clamping rod from the plug-in block, thereby releasing the limit of the plug-in block. At this time, the explosion-proof cover can be lifted upward, so that the explosion-proof cover drives the plug-in block to separate from the plug-in board, and then the explosion-proof cover can be taken down. Through the above structural setting, the explosion-proof cover can be opened quickly, thereby saving a lot of time and effectively improving the work efficiency of workers;

[0021] After adding new dry quenched coke, the explosion-proof cover is then closed, so that the explosion-proof cover drives the plug-in block to contact and squeeze the clamping rod, which causes the clamping rod to slide outward under force, and then the elastic force of the reset spring drives the clamping rod to reset, so that the clamping rod is engaged with the plug-in block again, thereby limiting the plug-in block and completing the installation of the explosion-proof cover.

[0032] By starting the fan 11, the fan 11 can send the VOCs waste gas in the incinerator 1 into the spray tower 12 through the connecting pipe 10, and then by starting the external water pump, the water pump sends water into the diverter 13 through the hose 15, and sprays it out in the diverter nozzle 14 through the diverter 13, so as to achieve the effect of spraying the VOCs waste gas, and the waste liquid after spraying will fall to the bottom end of the spray tower 12 by gravity, and through the setting of the sewage pipe 16, the waste liquid can be sent to the waste liquid collection box 17 through the sewage pipe 16, so as to achieve the collection of the waste liquid, so as to facilitate the centralized treatment of the waste liquid by the workers, and at the same time, through the setting of the staggered structure between the diverters 13, the VOCs waste gas will pass through the diverters 13 The gaps of the activated carbon plate 18 are used to float to the activated carbon plate 18 above.

[0033] Embodiment 2: Different from Embodiment 1, this embodiment realizes the rapid opening of the explosion-proof cover 2, thereby saving a lot of time.

When the plug-in block 4 drives the card slot to move to be parallel to the card rod 6, At this time, the elastic force of the reset spring 7 drives the clamping rod 6 to reset, so that the clamping rod 6 is engaged with the plug-in block 4 again, thereby realizing the limit of the plug-in block 4, and then completing the installation of the explosion-proof cover 2. At the same time, the explosion-proof cover 2 will also drive the sealing strip 3 to fit with the incinerator 1, thereby achieving a sealing effect, thereby preventing the VOCs waste gas generated during incineration from floating out and polluting the air.
