Smoke emission load adjusting and control system of thermal power plant

Abstract

The invention discloses a smoke emission load adjusting and control system of a thermal power plant. The system comprises a first smoke exhaust pipe, a second smoke exhaust pipe, a third smoke exhaustpipe, a fourth smoke exhaust pipe and a controller, wherein smoke outlets are formed in the top ends of the first smoke exhaust pipe, the second smoke exhaust pipe, the third smoke exhaust pipe and the fourth smoke exhaust pipe; smoke sensors are arranged at the inner side walls at all the smoke outlets; smoke inlets are formed in the bottom ends of the first smoke exhaust pipe, the second smokeexhaust pipe, the third smoke exhaust pipe and the fourth smoke exhaust pipe; a motor is arranged on one side of each smoke inlet; an angle sensor is arranged on the other side of each smoke inlet; anadjusting plate is arranged in the middle of the interior of each smoke inlet; and a first smoke flow sensor and a second smoke flow sensor are arranged at the top end of the inner side of each smokeinlet. The system has the beneficial effects that the smoke flow between different chambers of a dust remover can be automatically balanced and adjusted, so that the amount of the smoke flowing through each separation chamber is basically the same, and the defect of uneven distribution of the smoke flow between different chambers of an existing dust remover is overcome.

Description

technical field [0001] The invention relates to the technical field of adjusting the smoke discharge volume of a dust collector in a thermal power plant, in particular to a control system for adjusting the smoke discharge volume of a thermal power plant. Background technique [0002] The dust collector system of the existing thermal power plant is usually arranged in 4 rooms. In actual operation, the amount of flue gas processed by each room varies greatly, and the measured deviation can reach 50%. The deviation of flue gas volume will lead to high flue gas flow rate in some chambers, lower overall dust removal efficiency, and make the actual output of each ash bin pump in the ash removal system inconsistent with the design, resulting in the problem of poor ash removal. Especially for the bag filter, the deviation of the flue gas volume between different rooms will lead to a low life of the filter bag in the room with a large flue gas volume, seriously affecting the normal u...

Problems solved by technology

The deviation of flue gas volume will lead to high flue gas flow rate in some chambers, lower overall dust removal efficiency, and make the actual output of each ash bin pump in the ash removal system inconsistent with the design, resulting in the problem of poor ash removal

Especially for the bag filter, the deviation of the flue gas volume between different rooms will lead to a low service life of the filter bag in the room with a large flue gas volume, which will seriously affect the normal use of the equipment and cause economic losses to the enterprise.

[0003] For the problems in related technologies, no effective solutions have been proposed yet
