Description

Technical Field

[0001] The present application relates to the technical field of deacidification towers, and in particular to a deacidification tower suitable for secondary incineration treatment. Background Art

[0002] A deacidification tower is a device used to remove acidic gases from gases. It is mainly used in flue gas desulfurization and denitrification processes in industrial production. A large amount of waste gas will be generated in industrial production or garbage disposal. These waste gases contain a large amount of acidic substances. If they are directly discharged into the air, they will cause pollution to the surrounding environment. Therefore, a deacidification tower is needed to treat the waste gas.

[0004] The device collects acidic substances in the waste liquid through activated carbon on the inside of the hopper to achieve the effect of deacidification. However, the device only considers the treatment of waste gas in gaseous form. In reality, there may still be solid particles in the waste gas (such as the waste gas generated after garbage incineration in some scenarios), and secondary incineration is required to achieve a better overall treatment effect.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original deacidification tower structure. Utility Model Content

[0006] In order to overcome the problems existing in the related technology at least to a certain extent, the embodiment of the present application provides a deacidification tower suitable for secondary incineration treatment to solve the technical problem that the related technology proposed in the above background technology only considers the treatment of gaseous waste gas, and cannot achieve a better treatment effect in view of the fact that solid particles may still exist in the waste gas in practice.

[0007] The embodiment of the present application provides a deacidification tower that is suitable for processing a variety of materials. The deacidification tower includes a deacidification tower body, which is fixedly installed on the upper end of the base, and an incinerator is fixedly installed on the upper end of the deacidification tower body, and the incinerator is connected to the deacidification tower body through an exhaust pipe; a waste liquid collecting box, which is fixedly installed on the upper end of the base, and the waste liquid collecting box is connected to the bottom of the deacidification tower body through a waste liquid discharge pipe, the upper end of the waste liquid collecting box is connected to the distillation box through a distillation pipe, and the distillation box is fixedly installed on the upper end of the waste liquid collecting box, and the waste liquid collecting box is connected to the incinerator through a heat conduction pipe; a water tank, which is fixedly installed on the upper end of the base, and the water tank is connected to the distillation box through a circulating water pipe, a water pump is fixedly installed on the upper end of the water tank, and a water pipe is fixedly connected to the outside of the water pump, and a nozzle is fixedly connected to the tail end of the water pipe, and the nozzle is fixedly installed on the top of the deacidification tower body.

[0008] In a possible implementation manner, one-way valves are installed on the outsides of the exhaust pipe, the heat conducting pipe, the distillation pipe, the circulating water pipe, and the water conducting pipe.

[0009] In a possible implementation manner, the height of the distillation tank is higher than the height of the water tank.

[0010] In a possible implementation manner, the height at which the end of the water guide pipe is installed on the deacidification tower body is higher than the height at which the end of the exhaust pipe is installed on the deacidification tower body.

[0016] 3. The implementation scheme of the deacidification tower suitable for secondary incineration treatment is provided with a structure for improving the deacidification effect.

[0017] 4. The implementation scheme of the deacidification tower suitable for secondary incineration treatment is provided with a wastewater recovery structure. In this structure, the wastewater is discharged to the inside of the waste liquid collection box through the waste liquid discharge pipe. At the same time, the heat generated by the incineration of the incinerator will be transferred to the inside of the waste liquid collection box through the heat conduction pipe to heat the wastewater inside the waste liquid collection box.
