(54) yCTAHOBKA FOR THERMAL DISPOSAL OF WASTE OF ANIMAL COMPLEXES

one

The invention relates to devices for disposing of industrial / agricultural wastes, for example, pig-breeding complexes, and can be used in those sectors of the national economy, as a result of the activity of the KOTIOULAH, liquid wastes that are to be thermally disposed of. IQ

Waste treatment plants are known in which the treatment of the waste is carried out in a suspended state in a fluidized bed furnace. These units consist of a reaction volume, a lattice, blower mechanisms, and apparatus for feeding and removing t1J products.

However, the known installations are characterized by a low process efficiency due to the countercurrent supply of waste and the movement of disposal products, large dimensions and metal content.

Closest to the present invention is a plant for co-burning 25 household waste and sewage sludge, containing an evaporator with a heat exchange surface, a combustion chamber and a secondary combustion chamber, and a pipeline for condensed solid waste.

DON and flue gas disposal duct 2.

The disadvantages of the installation are the energy costs of atomization of waste and low efficiency due to the design of the combustion chamber, which has a low intensity of the process, large dimensions and intensity, which requires significant costs for the construction of the installation.

The purpose of the invention is to improve the working efficiency and reduce the size and metal consumption.

This goal is achieved by the fact that in a plant for thermal disposal of livestock waste. complexes containing an evaporator with a heat exchange surface, the combustion chamber and the afterburner killer,. the condensed and solid waste piping, the furnace, the chamber is made in the form of a pulsating combustion chamber with a resonant tube and connected to the afterburner chamber tangentially, and the pipeline for condensed and solid wastes is connected to the resonant tube of the pulsating combustion chamber.

The design of the installation allows for increased efficiency due to the fact that the liquid sediment after the evaporation compartment and the drying compartment is supplied by means of a pump (or ejecting device): Directly into the resonant tube of the pulsating combustion chamber. This same; the line in front of the pump is supplied with solid sediment from agricultural complexes. The sum of these two precipitates, which fall into the resonant tube of the pulsating combustion chamber, is sprayed and burned due to the kinematic energy of the hot gas stream after the pulsating combustion chamber, which operates in self-sucking mode through the air. As a result, an additional blower fan is not required. The implementation of the combustion chamber in the form of a pulsarunde combustion chamber with a high intensity of the processes, significantly reduces the size of the installation and its intensity, resulting in reduced installation costs.

The drawing shows schematically an installation for the thermal disposal of waste from livestock farms.

The installation contains an evaporator 1 with a heat exchange surface 2, on which there is an umbrella with a pipe 3 for discharging disposal products, a condenser 4 with pipes 5-7 for supplying the source liquid waste and heated vapors, respectively.

The evaporator is connected by pipe 8c to the dewatering chamber 9, which pipe 7 is connected to the condenser 4, the afterburning chamber 10 is placed in the dewatering chamber 9 and made in the form of a cyclone, to which pulsed burning chamber 11 is tangentially connected to the resonant pipe 12. Pipeline 13 for conveying and solid waste is connected to the resonant tube 12 of the pulsed combustion chamber 11. The afterburner chamber 10 has a device 14 for removing drying products and burning waste, which can be used to fertilize agricultural fields. The outer surface of the chamber 10 has screw ribs 15 designed to spiral the direction of flow of the fluid being lost and to increase the surface of contact with the heat transfer surface and, therefore, improve heat transfer.

The installation works as follows.

The pulsating combustion chamber 11 is turned on. Wastewater after mechanical treatment comes through

a condenser 4 to an evaporator 1 with a heat exchange surface 2 into which vapors after chamber 9 enter and flue gases after chamber 10 of afterburning. The vapors from the evaporator 1 enter the condenser 4 where they condense. The evaporated solution after the evaporator 1 enters the dewatering chamber 9 and, after passing along the fins 15, is dried and flows through the conduit 13 into the resonance tube 12

 pulsed combustion chambers 11. Sludge flows through the same pipeline after mechanical sewage treatment. Sediment sprayed with a kine-% .tic stream of flue gases, after

5, the combustion chamber of the pulsarium is finally dried and partially burnt in the co-current jets of the tenth gases of the chamber of the pulsary rotational combustion chamber connected tangentially to the chamber 10

0 afterburning. The flue gas flow, before passing to the lower part of the chamber, goes through the central pipe to the evaporator 1, and dried and partially dehydrated particles in the form of pellets enter the conical part of the afterburner chamber 10, from where they are removed by the device 14 (for example, auger).

The implementation of the proposed installation allows to increase the efficiency of the installation, significantly reduce its dimensions and intensity, and consequently, reduce the cost of its construction.
