Abstract

The invention can be used in the incineration of waste. The purpose of the invention is to increase the reliability of the system. The supply tank 2 is connected to the source 1 of the suspension supply pipe 3 to the pump 6, as well as the overflow pipe 4. The pipe 3 is connected to the bottom of the tank 2, and the intake pipe 5 connected to the nozzle 7 is also brought into the cavity of the tank through its bottom and installed possibility of axial movement. Increased reliability is achieved by eliminating stagnant zones in the tank, constant circulation of the slurry and controlling the flow rate by changing the hydrostatic difference between the level of the drain and the upper ends of the intake nozzles with variable entrance sections. 1 il.

Description

YES

one

The invention relates to energy and can be used primarily in incinerators for various wastes.

The purpose of the invention is to increase reliability.

The drawing schematically shows a suspension supply system.

The system contains a source of 1 suspension, consumable tank 2 with a supply pipe 3, overflow 4 and intake 5 nozzles. To supply the suspension to the supply tank 2, a pump 6 is installed on the supply pipe 3. The intake pipes 5 are connected to the nozzles 7 by the pipe 8. The tanks 1 and 2 are equipped with a stop valve 9.

The system works as follows.

The suspension from source 1 through line 3 is pumped by pump 6 to the lower part of the supply tank 2 and returned to source 1 through overflow pipe 4. By recirculation, a constant slurry composition is established. Vertical movement of the intake nozzles 5 for removal of the suspension to the nozzles 7 and the regulation of their inlet sections establish the required flow rate of the suspension. The flow rate is proportional to the level difference between the overflow pipe 4 and the upper ends of the intake pipes 5, as well as the area of their input

sections. The inlet sections of the intake nozzles 5 can be changed, for example, by installing washers with openings of different areas or installing diaphragms with an adjustable cross section.

Improving the reliability of the supply of suspensions in the proposed device compared with the known devices

S is achieved by eliminating stagnant zones in the supply tank, continuously circulating the slurry and controlling the flow rate by changing the hydrostatic differential between

15 the level of the drain and the upper ends of the intake nozzles with variable entrance cross sections without the use of regulating valves.
