Embodiment 1

[0080] In this embodiment, a high-pressure pump with a flow rate of 50 tons per hour is used to remove dust from the water curtain net of a 100-ton boiler. Two layers of water curtain dust collectors 2 are installed in the conveying pipeline 1, and seven high-pressure Nozzles 22, wherein the flow rate of each high-pressure nozzle 22 is 14L / S,

[0081] In this embodiment, the pressure of the flue gas is set between 200-600kpa, and the water pressure of the high-pressure nozzle is set at 700kpa to prevent the sewage from being carried away by the flue gas.

[0082] The embodiment of the water curtain net dedusting pipeline described in this embodiment is the same as the above embodiment.

[0083] After running through the pipeline, it can be obtained that the removal rate of the dust in the pipeline flue gas reaches 97.6%, and the pipeline of the present invention can efficiently remove the flue gas.

Abstract

The invention relates to a dust removal pipeline for a water curtain net. A high-pressure pump water spraying for weaving a water net for removing dust from smoke. The dust removal pipeline comprisesa conveying pipeline used for conveying smoke, at least two water curtain dust removers, at least two water collection tanks and a sewage pool, wherein the at least two water curtain dust removers arearranged in the conveying pipeline for weaving the water net; the water collection tanks are arranged on the outer sides of the water curtain dust removers for collecting sewage subjected to dust removal; the sewage pool is arranged below the water collection tanks and is connected with the water collection tanks for processing sewage in the water collection tanks. The high-pressure pump water spraying is used for weaving the water net, the water net adsorbs dust in the smoke to achieve an effect of smoke dust removal, the water net is used for removing dust to avoid a dust attachment situation, the blockage in the pipeline is avoided, and the dust removal efficiency of the dust removal pipeline is improved.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal, in particular to a water curtain net dust removal pipeline. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, the requirements for the purification of dusty gas generated in the production process are also continuously improved. At present, most of the dust-containing gas is filtered by traditional bag filter or filter element filter, and then discharged directly. In the discharged gas, there are still about 5% of the total amount of ultra-fine dust particles with a diameter of less than 5 μm that cannot be removed. Dust particles directly pollute the environment. Moreover, the disadvantages of the bag filter are also obvious. For example, the filter bag needs to be replaced frequently, and the life of the filter bag is also short. Especially under high temperature, corrosive environment and other working conditions, th...
