ECT ENVIRO TECH
Technical specification equipment and technology
The entire line for regulated thermal degradation consists of two parts:
- This is a thermal device, the source of heat is electrical energy.
- The controlled thermal degradation device meets the requirements for energy recovery of waste and is fully automated and mobile. This allows it to be used directly at the source of the waste (landfill, production waste).
- Simple installation, energy self-sufficiency
- The device has zero emissions.
- The facility consists of 3 reactors, each reactor has 4 chambers (reservoirs), i.e. in total the facility will have 12 chambers (reservoirs).
- Installed power supply is about 40 kW/hr, the maximum temperature in the interior of the reactor is 650 °C.
- Chamber size (container) – 300 mm diameter, length 2,000 mm. The volume of one container is about 141 litres.
- The capacity of the device varies from 3 to 4 m3 depending on the modulation of the temperature curve.
Variant Nr. 1
Dimensions Equipment with three reactors:
- 6 800 mm (length) x 2 400 mm (width) x 2 400 (height).
- Illustration as follows:
Technology – may be composed of individual elements:
- Drying equipment (input moisture of the processed material is reduced)
- Crushing and filling equipment
- Carbon cooling
- Gas cleaning and drying
- Cogeneration unit
- Pressure vessel
I. Drying equipment
- there are a large number of different dryers on the market for materials (drums, rotary, continuous etc.).
- for purposes of reducing moisture in the input material, a device for drying loose materials and a continuous drying method is appropriate
- the advantage is that the waste heat from the facility can be used as a heat source for the drying plant.
II. Crushing and filling equipment
- milling or crushing equipment ensures the achievement of a higher specific weight and input material.
- the homogenised input material is filled further into the reservoirs via a filling device.
III. Carbon cooling
- simple steel construction of shelf type with dimensions max. 2 000 mm (length) x 2 200 mm (height) x 2 500 mm (depth).
- it is used to store and cool carbon storage tanks from 180 degrees, when the container is removed from the device and placed in a shelving structure, where it is cooled to 70-80 °C. When this temperature is reached, carbon can be safely manipulated.
IV. Cleaning and drying of the gas
- if the gas contains a higher water content, the gas must be dried before being injected into the CHP unit.
- the gas can also contain tar aerosols, but these will be minimal but need to be simply filtered out through a particulate filter before using the gas itself.
V. Pressure vessel
- used for temporary possible storage of gas, in case of excess gas.
- One pressure vessel will have a floor plan of approximately 1,500 x 1,500 mm.
- More pressure vessels can be used as a temporary storage tank.
VI. Cogeneration unit
- used for power generation, using the heat released in the electricity generation process in an efficient way.
- the heat source is gas, or oil, which is the output from the process of controlled temperature degradation.
- A single three-chamber RTD device is capable of producing as much thermal energy as a source for a 100 – 250 kWh CHP unit, depending on the type of material processed, the chemical composition and the calorific value of the output from the controlled thermal degradation proces.
- there are many manufacturers of compressors on the market for filling the pressure vessel with gas
Variant Nr. 2
- Equipment for thermal degradation of tyres of large tyres with one large magazine.
- The reactor has a diameter of 950 mm and contains one magazine.
- The tyres are loaded into the container without pre-treatment, i.e. in whole.
- The device consists of 1 reactor and 1 radiator.
- The installed power input of the device is 30 kW/hr, the maximum temperature in the interior of the reactor is 320 °C.
- The size of the reactor is 950 mm diameter, length 1,800 mm.
A burning curve has been created for the thermal degradation of the tyres, which will take a total of 12 hours.
After cooling the reactor to about 180 °C, the reactor can be opened the existing container with a steel cord and carbon residue can be removed while inserting a new stake, i.e. a set of additional tyres ready for storage.
After further cooling, a steel cord can be easily selected from the removed batch. The process produces a gas that condenses through the radiator, transforming the whole of it into a liquid fraction. These are high calorific output products (liquid fraction and solid carbon fraction).
