Abstract
A method of immersing-burning-evaporating percolating water of second-phrase landfills, which could dispose percolating water of landfills, leach liquor of refuse burning factories and high concentration organic waste water. Burning landfilled gases or other goods as sources of energy, the resultant high-temperature gases are entered the inner of liquid of a two-stage evaporating unit, evaporating and concentrating the percolating water,the condensated liquor could be discharged for coming up to standards, the concentrated water should be solidified, landfilled, burned or recharged. The process could separate volatile organic compounds and water from percolating water, volatile organic components are mostly oxidizing into CO2 and H2O, which reduces the pollution on environment. Steam produced in the second-step evaporating unit could preheat the original percolating water, which improved heat conductive efficiency, and saving energy.
Description
Technical field
The invention belongs to the technology of garbage disposal field of environment protection, particularly the second order segmentation landfill percolate submerged combustion evaporation technology of landfill percolate and leachate of garbage burning factory and high concentrated organic wastewater processing.
Background technology
It is an important step of solid waste management that landfill is disposed, for a complete solid waste management system, and the landfill key element that is absolutely necessary.At present, the pollution of landfill yard control is still weak link, and the processing of landfill percolate is the difficult problem that efforts at environmental protection person faced all the time.Percolate output is big, Pollutant levels are high, the change of water quality scope is very big, not only annual more folded with the four seasons, the variation that alternately presents regularity in dry season, rainy season, and also show regular variation with landfill yard duration of service, maturity, and existing garbage leachate treatment process all exists complex process, the residence time is long, processing cost is high, the water quality after handling still has end item to be difficult to problems such as up to standard, can form pollution threat to surface water and underground water.
The percolate evaporation technology is not subjected to the influence of leachate quality mutability, has very strong capacity of resisting impact load.At present both at home and abroad the evaporation technology of Application and Development exists all that energy utilization rate is low, tail gas is difficult to problems such as processing.
Summary of the invention
The purpose of this invention is to provide a kind of economy, efficient, energy-conservation second order segmentation landfill percolate submerged combustion evaporation technology, it is characterized in that: the second order segmentation submerged combustion evaporation technology of described landfill percolate, be to be the energy with landfill gas or other merchantable fuels, the high-temperature fuel gas that landfill gas or other merchantable fuels produce after by gas burner feeds the liquid internal in the double flash evaporation unit, with the percolate evaporation, concentrate the back discharging or solidify the back landfill.
Concrete steps are as follows: at first percolate stoste or the percolate concentrated solution through just handling, after preliminary the filtration, enter the evaporation element 2 of fs by interchanger 4, by being the energy with landfill gas or other merchantable fuels, in the high-temperature fuel gas of gas burner 1 burning back generation enters percolate in fs evaporation element 2 and the subordinate phase evaporation element 3 respectively, the heat that is discharged carries out evaporation concentration to percolate, the opposing steam flow that fs evaporation element 2 produces burns to gas burner 1, and temperature is 750-850 ℃; The concentrated solution that fs evaporation element 2 produces enters subordinate phase evaporation element 3 and further evaporates, and maintains about 100 ℃, and the steam that subordinate phase evaporation element 3 produces carries out preheating through 4 pairs of percolate stostes of interchanger, discharges after the condensation; The concentrated solution that subordinate phase evaporation element 3 produces can solidify the back landfill, burn or recharge.
The invention has the beneficial effects as follows: 1). this second order segmentation submerged combustion evaporation technology, the energy evaporation concentration percolate that adopts landfill gas or other merchantable fuels submerged combustion to produce, realize volatile organic matter, the separation of moisture from percolate, and the steam that the subordinate phase evaporation element produces is used for the preheating of percolate stoste, improved heat transfer efficiency, save energy.2). the opposing steam flow that the fs evaporation element produces through the combustion flame high temperature sintering, can be removed wherein volatile organic matter and other non-methane carbohydrate to gas burner, and major part is oxidized to CO
2And water, reduce pollution to environment.

Fig. 1 is for handling the second order segmentation submerged combustion evaporation technology schema of landfill percolate.
Embodiment
The present invention is a kind of economy, efficiently, energy-conservation second order segmentation landfill percolate submerged combustion evaporation technology, technical process concrete steps as shown in Figure 1 are: at first percolate stoste or the percolate concentrated solution through just handling, after preliminary the filtration, enter the evaporation element 2 of fs by interchanger 4, by being the energy with landfill gas or other merchantable fuels, in the high-temperature fuel gas (750-850 ℃) of gas burner 1 burning back generation enters percolate in fs evaporation element 2 and the subordinate phase evaporation element 3 respectively, the heat that is discharged carries out evaporation concentration to percolate, the opposing steam flow that fs evaporation element 2 produces is to gas burner 1, through 750-850 ℃ of burning, volatile organic matter in the percolate is evaporated, and be back to gas burner by burning the destruction organic components, be oxidized to CO
2And water, thereby the organism in separation and the removal percolate; The concentrated solution that fs evaporation element 2 produces enters subordinate phase evaporation element 3 and further evaporates, and fluid temperature is still kept 100 ℃, and the steam of generation also is 100 ℃, and its steam is mainly by water vapor, CO
2, N
2Form, do not contain harmful gaseous constituent.The steam that subordinate phase evaporation element 3 produces carries out preheating through 4 pairs of percolate stostes of interchanger, discharges after the condensation, and this discharging is to make moisture evaporation under the prerequisite of national respective standard as much as possible reaching, and reaches separating of clean water and percolate concentrated solution.The concentrated solution that subordinate phase evaporation element 3 produces can solidify the back landfill, burn or recharge.
For realizing the target in two stages respectively, guarantee: the pH value of the percolate in the fs evaporation element maintains 4.5～5.5, and the pH value in the subordinate phase evaporation element is wanted corresponding increase by 0.3～0.5; The temperature that enters the high-temperature fuel gas of subordinate phase evaporation element can not be higher than the temperature of the high-temperature fuel gas that enters the fs evaporation element.
