PRODUCTS

Environmental protection dust removal system

The environmental protection dust collector produced by us is suitable for the recycling of environmental dust removal materials in metallurgy, electric power, chemical industry, building materials, machinery and other industries. features.

Screw

The company independently develops and designs seven advanced environmental protection and energy-saving vertical kilns with inner diameters of 6000, 5800, 5300, 4200, 4000, 3800, 3700, 3500, 3200, etc.

Blower

The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (and fuel tank), and drip nozzle.

Distributor

The distributor is a distributing device that distributes raw materials and solid fuels on the cross-section of the shaft kiln as required, also known as the "vertical cellar distributor". The distributor is one of the key equipment in the production of the shaft kiln.

Hoist

Winch, a light and small lifting equipment that uses a drum to wrap a wire rope or chain to lift or pull heavy objects, also known as a winch. The winch can be lifted vertically, horizontally or obliquely to pull heavy objects.

Unloading bucket

Star ash machine

The star-shaped ash extractor is a supporting equipment for the conical ash extractor. The star-shaped ash extractor discharges the limestone in the kiln through the rotation of the star rotor, and at the same time, it can always maintain a sealed state during the unloading process, so that the unloading ash does not stop the wind, so that the temperature in the kiln is always stable.

Environmental protection dust removal system

The environmentally friendly dust collector we produce is suitable for the recycling of environmental dust removal grade materials in metallurgy, electric power, chemical industry, building materials, machinery and other industries.

Environmental protection kiln design technology

Basic Theoretical Parameters of Lime Calcination

When lime is calcined, CaCO3=CaO(s) + CO2(g)-178.4KJ/mol Generally, CaCO3 begins to decompose between 880°C and 915°C. In order to increase the decomposition rate of CaCO3, the calcination temperature of limestone in the lime kiln should be maintained in the range of 950°C to 1200°C, and the temperature can reach 1250°C.

Process flow

After the limestone that has been processed and screened in the mine is transported to the limestone quarry in the plant, the qualified limestone is transported by the loader to the limestone storage silo in front of the kiln. The coal is also screened from the storage yard and then transported to the coal storage silo.

Cloth Equipment Design

After uniform mixing, it is lifted to the top of the furnace by the single-bucket elevator and put into the stone unloading bucket. The stone unloading hopper is controlled by the electrical switch to start turning at the angle specified by the four-point cloth. The hopper runs to the bottom of the inclined bridge and the pressure bar of the lower bell cap is pressed down by the weight of the material truck itself.

Calcination measurement and control

Furnace temperature detection: Limestone is calcined in the kiln through three sections, namely the preheating section, combustion section and cooling section. According to the kiln thermal theory calculation, the preheating section should account for 25% of the kiln height, and the calcination section accounts for 50%. , the cooling section accounts for 25%.

Monitoring and Automation

The kiln is equipped with 6 monitoring points, which are distributed in various key parts of the kiln. The operator can know all kinds of kiln operation conditions in the control room and observe the various operation states of the kiln at any time.

Dust removal system

The kiln gas comes out of the kiln roof and passes through the multi-rotor separator to remove dust, then contacts with alkaline water through the desulfurization chamber to remove sulfur dioxide, and after cooling and dehydration, it is discharged to the chimney by the induced draft fan.
