Method and equipment for industrially producing clean liquid fuel by utilizing household waste or sludge press water

Abstract

The invention relates to a method and equipment for industrially producing a clean liquid fuel by utilizing household waste or sludge press water. The equipment mainly comprises an adjusting kettle, a filtering tank, an impurity removing tank, a descaling tank, a multifunctional reaction kettle and a semi-finished product and product tank which are arranged sequentially in a technological process. In addition, the invention further discloses a method for producing AB-level secondary clean liquid dye in the equipment. The combustion temperature of the clean dye can reach up to 1000 to 1500 DEG C. The method and the equipment provided by the invention have the advantages of no secondary pollution in production process, less investment and low cost, environmental protection, waste utilization, energy conservation and efficacy enhancement, thereby being a novel environmental protection project. Therefore, the method and the equipment provided by the invention can be widely applied to treatment of municipal solid waste in China at present, and have significant social effects.

Description

technical field

[0001] The invention relates to the fields of environmental protection engineering and energy, in particular to a method and equipment for industrially producing clean liquid fuel from domestic garbage or sludge (water content < 85% by weight) by squeezing water (or seepage). Background technique

[0002] At present, after domestic and foreign municipal solid waste (sludge) has been treated and disposed of by various methods (landfill, incineration, composting, recycling), the squeezed water (leakage) produced can only be treated by conventional sewage treatment methods. Treat it to the point where it can be discharged up to the standard or can be used as water, and because the COD content of these squeezed water (leakage) is particularly high, some COD will reach 60,000-80,000, so the investment cost of treating this type of wastewater is high ,High difficulty.

Embodiment 1

[0025] In the equipment for the industrial production of compressed water from domestic waste (leakage) and domestic sludge (water content below 85% by weight) into clean liquid fuels, direct current pumps 1-1 are used to squeeze water from domestic waste and sludge Drive into the waste liquid tanks 3-1, 3-2 respectively, there are pipeline connections between the DC pump 1-1 and the waste liquid tanks 3-1, 3-2, and check valves 2-1 are respectively installed on the pipelines , 2-2, the bottoms of the waste liquid tanks 3-1, 3-2 are equipped with outlets, which are connected by pipelines, and check valves 2-3, 2-4 are respectively installed on the pipelines to control the discharge. The pipelines equipped with check valves 2-3 and 2-4 are connected to the mechanical hydraulic diaphragm metering pump 4-1, and the squeezed water is metered and pumped into the regulating kettle 5 by the mechanical hydraulic diaphragm metering pump 4-1. Add 0.05% by weight of flocculant polymerize...

Embodiment 2

[0027] With the mechanical-hydraulic diaphragm metering pump 4-6, the B-grade clean liquid fuel of Example 1 in the finished product tank 12-1 or 12-2 or 12-3 is pumped into the multifunctional reaction tank 10-2 by the required amount through the pipeline, Enter from feed port 22-1, then gasoline and ammonia liquid additive are added respectively from the feed port 22-2 of multifunctional reaction tank 10-2, the add-on of gasoline additive is 7 weights of B grade clean liquid fuel amount %, the add-on of ammoniacal liquor additive is 5% by weight of B grade clean waste liquid fuel, thus starts the mixing system on the multifunctional reaction tank 10-2 to stir at a slow speed for 30 minutes, then in the additive feeding of multifunctional reaction tank 10-2 Port 15-5-1, 15-5-2, and 15-5-3 add potassium permanganate, hydrogen peroxide, and camphor essence additives respectively, and the addition amounts are respectively 0.2% by weight and 0.03% by weight of the amount of B-leve...

Embodiment 3

[0029] Example 3 The steps of industrialized production of clean liquid fuel are the same as in Example 1, except that the ratio of feed squeezed water:methanol is 35:65 parts by weight, and the combustion furnace temperature of Class B clean liquid fuel can reach 900 degrees.
