Description

The invention relates to the field of fuel combustion and can be used in thermal power plants.

The aim of the invention is to increase reliability and efficiency.

FIG. 1 shows a system for the preparation of liquid fuels for combustion; in fig. 2 - multi-way crane, longitudinal section.

sent to the exhaust manifold 21. When regenerating a contaminated filter, for example filter 4, rotate the rotor 13 until the inlet 8 of the crane 9 is connected to which the anti-rinsing filter 4 is connected to the outlet of the outlet 10. Then opening the distribution valve 17 is simultaneous compressed air supply from the source 16 to the locking mechanism 14 and the system contains filters 1-6 with pipelines 7 of counter-current flushing, each is mechanism 15. Since the pressure of which is connected to one Much of the development of the locking mechanism 14

inlet nozzles 8 of a multi-way valve 9, the outlet nozzle iO of which is connected via valve 1 to the damper tank 12. The multi-way crane 9 has a rotor 13 equipped with a pneumatic locking mechanism 14, and valve 11 is an actuator 15. The outlet nozzle 10 of the crane 9 communicates with one of inlet nozzles 8 nosredstvom rotor 13.

less than that of the actuator 15, it is triggered first and fixes the position of the rotor 13. When the operating pressure is reached, the actuator 15 opens the valve 11. At the same time, the rinsed filter 4 is connected to the damping capacity 12, which is under atmospheric pressure. The rinsing time of the filter is determined by the volume of the tank 12, after the stop mechanism 4 of the rotor 13, together with which 20 is pneumatic distribution: 1, positive

with the actuator 15 of the valve 1 are connected to the source 16 of compressed air through the distribution valve 17. Filters 1-6 have shut-off members 18 and 19 at the inlet and outlet nozzles and crane 1 / closes, the air pressure in the actuator 15 and the stopper mechanism 14 drops , as a result, the mechanism 15 is activated and closes the valve 1, and the locking mechanism 14 unlocks the inlet and outlet manifolds 25 -pop 13. Thus, for all time open 20 and 21. The system of preparation of the liquid 11 valve 11 rotor 13 multi-way crane and 9 is blocked from displacement. Flush filter 4 is complete. If necessary, rinse another filter, for example 5. the outlet 10 is reported using

fuel for combustion works in the following way.

The contaminated fuel from the exhaust manifold 20 is guided through the locking bodies 18 to the filters 1, 3 and 5 of the first purification stage, and then to the filters 2, 4 and 6 of the second stage. Filtered fuel

When regenerating a contaminated filter, for example filter 4, rotate the rotor 13 until the inlet 8 of the crane 9 is connected to which the anti-rinsing filter 4 is connected to the outlet of the outlet 10. Then opening the distribution valve 17 is simultaneous compressed air supply from the source 16 to the locking mechanism 14 and the actuating mechanism 15. As the response pressure of the locking mechanism 14

an optional mechanism 15. Since the trigger pressure of the locking mechanism 14

less than that of the actuator 15, it is triggered first and fixes the position of the rotor 13. When the operating pressure is reached, the actuator 15 opens the valve 11. At the same time, the rinsed filter 4 is connected to the damping capacity 12, which is under atmospheric pressure. The flushing time of the filter is determined by the capacity of tank 12, after the zapkkran 1 / closes, the air pressure in the actuator 15 and the stopper mechanism 14 drops, as a result, the mechanism 15 is activated and closes the valve 1, and the stopper mechanism 14 unlocks the ro-pop 13. Thus, for the entire duration of valve 11 opening, the rotor 13 of the multi-way valve 9 is blocked from displacement. Flush filter 4 is complete. If necessary, rinse another filter, for example 5. the outlet 10 is reported using

a rotor 13 with an inlet 8 to which the piping 7 of the filter 5 is connected, and the regeneration process is repeated.
