Environmental Division - Incinerator & Air pollution prevention facilities

Incinerator Facility

By burning waste or solid fuel (liquid) Reduction and stabilization facilities. Through improved design and shape to fit the customer's requirements, we are striving to achieve high durability and maximize combustion efficiency.

Stoker Type

  • One of the most widely used type of incinerator, and move through the grate of the various types of waste mixing, combustion, emissions are to facilitate the moving type is the representative types of incinerators.
    Grate structure, mode of operation, the direction of movement, and how to follow numerous shapes.

Rotary Kiln Type

  • Viscous waste, hazardous waste of caloric demonstrate exceptional ability, and a rotating cylindrical furnace of a type that is dry and burning.
    Has a good stirring effect, and at the same time, the shape of the waste digestion can be one problem and efficient supply of combustion air to the heat dissipation due to the thermal efficiency is relatively low disadvantage.

Fluid Bed Type

  • Charge the heat medium such as sand by blowing hot air drying and fluidized bed combustion by forming a type that is momentarily.
    General difficult to burn in an incinerator, flame retardant suitable for incineration in the mechanical parts inside the less easy to maintain, but the problem with pre-separation and restored the flow of the medium has a problem.

Air pollution prevention Facilities

Facilities for noxious gases arising from industrial processes to reliably handle.
Alternative design for customer ease of use and operational savings and partial blending applied to satisfy customers, and make unremitting efforts.

Cyclone

  • Granted by the centrifugal force on the particles, the particles contained in the gas given the turning movement proportion of coarse particles in a particle separation device.
    The higher the efficiency of the gas flow rate, increasing the pressure loss of the one is increased. So that the design is within the optimum range, there's a lot of gas inside a single cyclone that uses multiple forms of the principle of multi-cyclone are also used.

Bag filter

  • Particles contained in the dirty gas filter is a principle that filtered through the filtration surface using big one Filter media expect from the surface reaction with various powders, and expect high collection efficiency in the device. Composition of the gas with properties depending on the chemical Filter, so are used in many ways.

Dry Reactor

  • Mainly used for acid gas removal device is induced by the neutralization reaction that induces a sufficient residence time and turbulence to maximize Efficiency somewhat, but a simple device, so it should be sufficient to remove the device initial.

Wet Reactor;Scrubber

  • Exhaust gas to absorb and neutralize the reaction temperature at reducing as a principle, and dispose of the neutralization reaction and the efficiency of the exhaust gas is the most stable are known to be excellent.
    But the process is virtually independent of waste water use will cause waste water to handle the process rather than as a multi-uses.

SDR ; Semi-Dry Reactor

  • SDR (SDA) is widely known as, complementary advantages and disadvantages of wet and dry between the dry and wet is a facility that can get better efficiency.
    Similarly, small amounts of neutralizing the reaction and adsorption reaction has the advantage of being insane.
    In addition, waste water does not occur does not cause secondary pollution.

Adsorbers

  • Hazardous substances contained in the gas by using various adsorbents to adsorb as a way to remove impurities, moisture, odors, etc. used.
    Activated Carbon Adsorption of organic matter by how much is being used, in addition to activated carbon, acid clay, silica gel, zeolite, etc. are also used.
    Depending on the amount that passes through the adsorbent effective sorbents appears when using the same standards of selection is also very important task.
