Novel dry desulfurization and dust removal device

Abstract

The invention discloses a novel dry desulfurization and dust removal device. The device comprises a cyclone dust collector, a high-pressure induced draft fan and a bag type dust collector, the cyclonedust collector is connected with the high-pressure induced draft fan through a flue; the high-pressure induced draft fan is connected with the bag type dust collector through a high-pressure flue; aflue gas inlet pipe is arranged at the front section of the cyclone dust collector; the other side of the bag type dust collector is connected with a chimney; three chambers are arranged in the bag type dust collector; the middle bin chamber is a dust removal cloth bag chamber; activated coke bins are arranged on the two sides, dust remover flue gas inlets are formed in the outer sides of the activated coke bins and connected with a high-pressure flue, feeding bins are arranged at the tops of the activated coke bins, discharging inserting plates are arranged at the bottoms of the activated coke bins, feeding pipes are arranged at the tops of the feeding bins, and the feeding pipes are connected with an elevator. According to the device, a desulfurizing agent is not needed in actual use, only active coke particles need to be added, the operation cost is low, circulating water is not needed in the desulfurization process of the device, and no pollution is caused to the ground surface andunderground water resources.

Description

technical field [0001] The invention relates to the field of desulfurization and dust removal, in particular to a novel dry desulfurization and dust removal device. Background technique [0002] With the promulgation of various national environmental protection laws and regulations, environmental protection standards continue to improve, and the environmental protection pressure faced by enterprises is also increasing. Various pressures are forcing companies to develop towards compliance. Only by actively implementing various environmental compliance work can enterprises meet the increasingly stringent requirements of environmental administrative law enforcement and supervision, prevent environmental legal risks, and gain more advantages in market competition. In recent years, in my country, the area of ​​pollution hazards caused by sulfur dioxide emissions has reached 30% of the country's land area. The discharged pollutants have brought serious threats to the atmospheric ...

Problems solved by technology

[0003] The invention solves the problems in the prior art that the desulfurization efficiency of the currently used desulfurization tower is not high, and a large amount of desulfurizer is required to achieve the desulfurization effect, which increases the cost of desulfurization, etc., and provides a new type of dry desulfurization and dust removal device. When it is applied, the flue gas entering the pneumatic scrubber, dust removal and desulfurization purifier is evenly distributed through the special internal structure and forms a rotating and rising turbulent air flow, which is in reverse contact with the falling desulfurizer, and the turbulent flue gas will continuously pulverize the desulfurizer Form into small droplets, thereby greatly increasing the contact area between the flue gas and the desulfurization agent, improving the desulfurization efficiency, and finally reducing the amount of desulfurization agent used in the desulfurization process, thereby reducing the cost of the desulfurization process and reducing the desulfurization investment of enterprises
