If the part of waste water can be directly recycled, the equipment investment and the operating cost can be greatly reduced, and the enterprise profit is increased.
Based on the above, the embodiment of the invention provides a system and a method for recycling hazardous waste incineration high-salt wastewater, which can reduce equipment investment and operation cost of high-sulfur and high-halogen hazardous waste incineration projects.
In order to provide a thorough understanding of the present invention, a detailed structure will be set forth in the following description in order to explain the present invention. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.
The system and the method for recycling the high-salinity wastewater generated by burning the hazardous waste are further described with reference to the accompanying drawings.
Referring first to fig. 1, fig. 1 shows a schematic diagram of a system for recycling hazardous waste incineration high salinity wastewater according to an embodiment of the present invention. As shown in fig. 1, the system for recycling hazardous waste incineration high-salinity wastewater according to the embodiment of the present invention includes: the wet deacidification tower 101 is used for performing wet deacidification on flue gas generated by burning high-sulfur and high-halogen hazardous wastes by using alkali liquor; the high-salinity wastewater collection tank 102 is connected with the wet-method deacidification tower 101 and is used for collecting alkali liquor with the salt content reaching the preset concentration in the wet-method deacidification tower 101 to obtain high-salinity wastewater; the quenching tower 103 is connected with the wet deacidification tower 101 and is used for receiving the flue gas subjected to wet deacidification; and the high-salt wastewater supply unit is respectively connected with the high-salt wastewater collection tank 102 and the quenching tower 103 and is used for spraying the high-salt wastewater in the high-salt wastewater collection tank 102 into the quenching tower 103 so as to evaporate the high-salt wastewater by utilizing the heat of the flue gas and simultaneously cooling the flue gas by utilizing the high-salt wastewater.
Illustratively, a rotary kiln, a secondary combustion chamber and a waste heat boiler (not shown) are arranged before the wet deacidification tower 101. The high-sulfur and high-halogen dangerous waste is ignited in the rotary kiln and is combusted in a negative pressure state, the dangerous waste slowly moves along the inclined direction of the rotary kiln and is fully combusted for about 1 hour, residues enter a water seal slag conveyor to be discharged, unburned substances escaping from the rotary kiln are further combusted in a secondary combustion chamber, and 99.99 percent of harmful gases such as dioxin are eliminated through high-temperature combustion at 1100 ℃. High-temperature flue gas in the secondary combustion chamber enters a waste heat boiler, the waste heat boiler is used for heating circulating water by utilizing the waste heat of the flue gas to generate steam, and then a steam turbine drives a generator to generate electricity, so that the heat in the flue gas is fully utilized.
Because the hazardous waste burned in the rotary kiln is high-sulfur and high-halogen hazardous waste, a large amount of acidic substances are generated in the burning process, and deacidification treatment needs to be performed on the flue gas generated by burning the acidic substances by adopting deacidification equipment. Exemplarily, the content of sulfur + chlorine of the hazardous waste is more than 10%. The deacidification equipment adopted in the embodiment of the invention is a wet deacidification tower 101, which is used for receiving the flue gas containing the acidic substances and performing wet deacidification on the flue gas by using alkali liquor.
Illustratively, a wet acid removal tower circulating pump 107 is arranged outside the wet acid removal tower 101, circulating alkali liquor is sprayed out from the wet acid removal tower 101 through a spray nozzle by the wet acid removal tower circulating pump 107, and flue gas passes through the wet acid removal tower 101 from bottom to top, passes through the atomized alkali liquor and is neutralized with the alkali liquor, so as to achieve the purpose of absorbing acid gas in the flue gas.
After the alkali liquor absorbs a certain amount of acid gas, the salt content of the alkali liquor reaches a predetermined concentration, and the alkali liquor cannot further absorb the acid gas, so that the alkali liquor needs to be treated. The salt content of the high-salt wastewater is generally 60000mg/L-80000mg/L, and the main components are NaF, NaCl, NaSO4 and NaBr. Because the hazardous waste is fully combusted in the rotary kiln and the second combustion chamber, the COD (chemical oxygen demand) content in the high-salinity wastewater is very low, so that the requirement of the water index of the quenching tower 103 can be met, the high-salinity wastewater does not need to be separately treated, and the equipment investment and the operation cost are saved.
Illustratively, a high-salinity wastewater pipeline 106 is connected to the bottom of the wet-method deacidification tower 101, and is used for guiding the alkali liquor with the salt content reaching the preset concentration and settled at the bottom of the wet-method deacidification tower 101 into a high-salinity wastewater collecting tank 102 connected to the other end of the high-salinity wastewater pipeline 106 for storage, and injecting the alkali liquor into the quenching tower 103 through a high-salinity wastewater supply unit.
Wherein the high-salinity wastewater supply unit comprises a quenching pump 104 and a quenching lance 105. The high salinity wastewater collection tank 102 is connected to a quench pump 104 through a pipe, and the quench pump 104 is connected to a quench lance 105 provided at an upper portion of the quench tower 103 through a pipe. The high-salinity wastewater in the high-salinity wastewater collection tank 102 is conveyed to a quenching lance 105 by a quenching pump 104, and is injected into the quenching tower 103 by the quenching lance 105.
Meanwhile, the quenching tower 103 receives the flue gas deacidified in the wet deacidification tower 101 through a flue gas pipeline, and the other end of the flue gas pipeline is connected with the upper part of the wet deacidification tower, so that the flue gas enters the quenching tower 103 from top to bottom and is mixed with the high-salinity wastewater sprayed by the quenching spray gun 105. In one embodiment, the quench spray gun 105 forms highly atomized droplets of high salt wastewater with compressed air and injects the atomized high salt wastewater into the quench tower 103. In the quenching tower 103, the highly atomized droplets are fully contacted with the high-temperature flue gas, so that the temperature of the high-temperature flue gas is reduced from 550 ℃ to 200 ℃ within 1s, thereby achieving the purpose of inhibiting the generation of dioxin.
On one hand, the high-salinity wastewater can cool the flue gas, so that the fresh water amount required by the quenching tower is reduced; on the other hand, moisture in the high-salinity wastewater contacting with the high-temperature flue gas is evaporated, a part of fly ash formed by solid salinity is deposited at the bottom of the quenching tower 103 and is discharged through an ash discharge port arranged at the bottom of the quenching tower 103, and the other part of fly ash enters a rear flue gas treatment device along with the flue gas, for example, is intercepted by a dust remover arranged behind the quenching tower 103, and the dust remover comprises but is not limited to a bag-type dust remover.
In some embodiments, other flue gas treatment devices may be disposed before and after the quench tower 103, and embodiments of the present invention are not limited in this respect.
Based on the above description, the system for recycling hazardous waste incineration high-salinity wastewater provided by the embodiment of the invention has the following advantages:
1. the high-salinity wastewater can reach the water index of the quench tower, so that the equipment investment and the increase of the operation cost caused by the independent treatment of the high-salinity wastewater are saved;
