Abstract

The utility model discloses an automatic desulfurization and dust removal device, the structural features of which are as follows: an air inlet is arranged on the upper left of the cyclone centrifuge, the upper end is an air outlet pipe, the lower end is an ash storage chamber, the bottom of the ash storage chamber is a dust outlet, and the bottom of the ash storage chamber is a dust outlet. The air inlet is connected to the air outlet pipe, and at a certain height is a gravity sensing partition, the lower end is a sediment collection chamber, the bottom is a sewage outlet, a dial, a water level sensor and a liquid inlet valve are set somewhere in the reaction pool, and the upper end is a Gas storage room, the right end of the gas storage room is connected to the concentration sensor, and then the gas outlet. The effect of this practical automatic desulfurization and dust collector is that the flue gas containing sulfur and dust enters the centrifuge for centrifugal dedusting and then passes through the reaction tank. The sulfur flue gas is absorbed by Ca(OH)2, and discharged after the concentration measurement reaches the standard, and the flue gas that does not reach the standard is returned to the air inlet, so as to achieve a higher dust removal effect.

Description

Automatic desulfurization and dust removal device

technical field

The utility model relates to a desulfurization and dust removal device, in particular to an automatic desulfurization device for a coal-fired boiler.

Background technique

Automatic desulfurization and dust removal devices are very common in the field of coal-fired boiler evolution. The basic principle is that the sulfur-containing and dust-containing flue gas enters the centrifuge for centrifugal dedusting and then passes through the reaction tank. The unremoved sulfur-containing flue gas is absorbed by Ca(OH)2, After the concentration measurement reaches the standard, it is discharged, and the flue gas that does not meet the standard is returned to the air inlet, so as to achieve a higher dust removal effect. Although the traditional desulfurization and dust removal method has high dust removal efficiency, it will generate a large amount of sewage by spraying and absorbing smoke, and the structure is complicated.

Contents of the invention

The purpose of this utility model is to provide an automatic desulfurization and dust removal device, which uses physical and chemical methods for desulfurization and dust removal, that is, the sulfur-containing and dust-containing flue gas enters the centrifuge for centrifugal dust removal and then passes through the reaction pool, and the unremoved sulfur-containing flue gas is absorbed by Ca( OH)2 absorption, after the concentration measurement reaches the standard, it is discharged, and the flue gas that does not meet the standard is returned to the air inlet, so as to achieve an efficient sulfur removal effect.

The utility model is achieved in this way, an automatic desulfurization and dust removal device, which includes an air inlet, an ash storage chamber, a dust outlet, an air outlet pipe, a reaction pool, a partition, a gravity sensor, a sewage outlet, a liquid inlet, Dial, water level sensor, exhaust port, concentration sensor, air outlet; it is characterized in that: the air inlet is set on the upper left of the cyclone centrifuge, the upper end of the cyclone centrifuge is the air outlet pipe, the lower end of the cyclone centrifuge is the ash storage chamber, and the bottom of the ash storage chamber It is the dust outlet, the air inlet of the reaction tank is connected to the air outlet pipe, and a certain height of the reaction tank is a gravity induction partition, the lower end of the gravity induction partition is a sediment collection chamber, and the bottom of the reaction tank is a sewage outlet , a dial and a liquid inlet are set somewhere in the reaction pool, the upper end of the reaction pool is a gas storage chamber, the upper end of the gas storage chamber is connected to a concentration sensor, and the concentration sensor is connected to the gas outlet.

The gravity sensing partition of the utility model is arranged at the lower end of the dial and the liquid inlet.

The upper end of the liquid inlet of the utility model is provided with a water level sensor, and the water level sensor is at the same height as the dial.

The effect of this practical automatic desulfurization and dust collector is that the flue gas containing sulfur and dust enters the centrifuge for centrifugal dedusting and then passes through the reaction pool. The flue gas that does not meet the standard is returned to the air inlet, so as to achieve a higher dust removal effect.
