Description of the application for a utility model: Plant for the production of cement

The utility model relates to the production of building materials, in particular, to the production of cement.

A known installation for the manufacture of cement and other building materials / I /, including installed in the technological sequence of bunkers for cement raw materials with feeders and transporting the device, raw material mill, about: a kiln, cold linen, estimated heat .

Due to the introduction of cement raw material heaters, the installation allows to reduce energy consumption, however, it does not provide for the blasting of municipal waste in the furnace.

Also known complexes for the production of cement / 2 /, including bunkers for cement raw materials about feeders, conveying devices, a raw mill, a kiln, a refrigerator, a dust-cleaning system.

In these complexes it is also impossible to use municipal waste for incineration in an oven, because The furnace is loaded through a sludge feeder located at the front end of the furnace and having a small through hole for the supply of sludge. When municipal waste is supplied, the sludge feeder will become clogged, which will lead to the impossibility of supplying sludge through it and stopping production.

waste and reducing the consumption of raw materials and fuel during cement production.

This goal is achieved by the fact that in a plant for the production of cement containing bunkers for cement raw materials with a feeder and conveying devices, a raw mill, a refrigerator, a dust cleaning system, a kiln, the latter is equipped with a side hatch for loading solid municipal waste through it.

The drawing shows a plant for the production of cement. The installation includes silos I for cement raw materials with feeders 2, conveying devices 3,4,5, raw mill b, batcher 7, elevator 8, kiln 9 with side hatch 10, refrigerator II, cyclone 12, electrostatic precipitator 13, smoke exhauster 14, outlet pipe 15.

Installation works as follows.

Cement raw material from bunkers I is fed through a feeder 2 by a belt conveyor 3 to a raw mill b. The crushed raw materials are sent to the elevator 8, where additives are also supplied, if necessary, from the dispenser 7.1h of the elevator 8. The raw materials are added to the kiln 9, where the cement clinker is formed, which then, after cooling in the refrigerator II, is fed through the plate conveyor 4 to grind to obtain cement.

The gases entering the furnace 9 are sent to the cyclone 12 for dust cleaning and then to the electric filter 13, of which the deposited dust is returned via the screw conveyor 5 to the elevator 8, and the cleaned gases are exhausted through the pipe 15 through the pipe 15 to the atmosphere. The presence of a side hatch 10 in the kiln 9 allows loading into the furnace and burning solid municipal waste in it, both in the form of briquettes and in a loose state.

In the process of pre-sorting, items are removed from the municipal waste, the combustion of which emits harmful

Bf

substances (chlorine, fluorine, etc.). Then solid waste briquettes

or in a loose state through the side hatch 10 is loaded into the furnace 9,

why the oven is first stopped.

Solid waste incineration in the furnace gives a triple positive

Effect:

-saving of cement raw materials;

-decrease in fuel consumption;

-improving the environmental situation, because utilization of municipal waste leads to the elimination of urban landfills, from which

choking our cities. Patent Attorney Authors:
