Abstract
The utility model discloses a device for landfill leachate returns and spouts, it is by filtration liquid conveyer pipe, heater, hot -water line and burns burning furnace and constitute. It can effectively solve the problem that the furnace temperature declined to a great extent to save the fire coal, reduced the unnecessary economic burden of enterprise.
Description
Technical field
This utility model relates to field of waste incineration, a kind of device returning spray for percolate.
Background technology
Percolate refer to rubbish during long-term stacking, due to the sewage that the Organic substance in rubbish decomposes or precipitation is formed.The feature that this sewage has nitrogen content, heavy metal is high, processes bad meeting and causes environmental pollution.At present, it is typically with back in percolate is transported to incinerator by spray technique carrying out burning, evaporating in the power plant utilizing waste incineration, thus effectively reduces the pollution to environment.
What now power plant was commonly used return spray technique is percolate is delivered directly to incinerator in process, as shown in Figure 1, owing to percolate is Normal Atmospheric Temperature Liquid, return specking and be generally arranged at again the position of overfiren air port height, as shown in Figure 3, position is relatively low, so often causing furnace temperature to decline to a great extent when returning spray, is also possible to make boiler extinguish time serious.Furnace temperature can decline 100～200 DEG C in general, the most, needs to increase fire coal in a large number and, in order to improve furnace temperature, brings the biggest economic pressures to enterprise, does not also meet the energy policy of country.
Utility model content
The purpose of this utility model is contemplated to the deficiency overcoming existing percolate to return spray technique, it is provided that a kind of new percolate returns spray apparatus, and it can effectively solve problem above, saves fire coal, reduces the financial burden that enterprise is unnecessary.
For achieving the above object, the technical solution adopted in the utility model is: a kind of device returning spray for percolate, and it is made up of percolate conveying pipe, heater, hot-water line and incinerator.
Described percolate conveying pipe passes in the middle of heater.
Described heater one end is connected with hot-water line, and the other end connects outlet pipe.
Described hot-water line is connected with several incinerators respectively.
2 percolate nozzles it are separately installed with on the furnace wall of the air flue horizontal position of described incinerator.
The inner side of described percolate nozzle is provided with control valve a, for controlling the amount of the percolate of ejection.
On described outlet pipe, control valve b is installed, the amount that hot water is discharged in controlling heater.
Described hot-water line is provided with control valve c with the junction of heater, flows into the amount of heater for controlling hot water.
Described hot-water line is provided with control valve d with the junction of incinerator, flows into the amount of hot-water line for controlling hot water.
The beneficial effects of the utility model are: on the one hand owing to utilizing the waste heat of incinerator platoon water fully to be heated percolate so that reduce with the temperature difference in incinerator from the temperature of the percolate of percolate nozzle ejection；On the other hand it is arranged on air flue horizontal position due to percolate nozzle, the percolate of ejection is because being acted on by inverse flue gas stream, be in seemingly enter non-enter state, so it is long in high temperature combustion zone residence time, and can promptly be pumped under the effect of flue negative pressure after Qi Hua, therefore furnace temperature and boiler combustion be affected the least.
