Embodiment 1
[0014] A saline waste liquid incineration and recovery system provided in this embodiment has a structure such as figure 1 As shown, it includes membrane fireplace body, semi-dry quenching tower, Venturi reactor, air box bag filter, spray scrubber, absorption tower and independent chimney. The membrane fireplace body passes through membrane wall flue and membrane type The wall boiler is connected, the smoke outlet of the membrane wall boiler is connected with the air inlet of the semi-dry quenching tower, and the top of the semi-dry quenching tower is equipped with an atomizing device, and the atomizing device is atomized by extracting the lye in the lye pool by the quenching pump. At the bottom of the semi-dry quenching tower, there is a waste liquid outlet leading to the sewage pipeline; the gas outlet of the semi-dry quenching tower is connected to the inlet of the Venturi reactor, and the feeding port of the Venturi reactor is equipped with a star-shaped discharge for addin...

The invention relates to a salt-containing liquid waste incineration and recovery system. The salt-containing liquid waste incineration and recovery system comprises a membrane-wall furnace body, a semi-dry quench tower, a Venturi reactor, an air chamber type bag dust collector, a spray scrubber, an absorption tower and a detached chimney. The membrane-wall furnace body is connected with a membrane-wall boiler through a membrane-wall flue, a smoke outlet of the membrane-wall boiler is connected with a gas inlet of the semi-dry quench tower, an atomization device is arranged at the top of the semi-dry quench tower and is used for atomization by using a quench pump for extracting alkali liquor in an alkali liquor pond, and a liquid waste outlet formed in the bottom of the semi-dry quench tower leads to a drainage pipeline. The salt-containing liquid waste incineration and recovery system has the advantages that since a membrane-wall furnace is used for incineration and heat exchange, utilization ratio of waste heat obtained by liquid waste incineration is increased effectively, the defect of proneness to blockage of a traditional furnace shape can be overcome, and waste discharge is smooth; by the aid of heat insulation materials, corrosion to the furnace body is reduced greatly, and service life of the furnace body is prolonged; besides, 15-20% of salt content can be recovered, and liquid waste treatment cost is lowered.
Description
technical field [0001] The invention relates to an incineration disposal device, specifically a saline waste liquid incineration and recovery system, which belongs to the technical field of environmental protection equipment. Background technique [0002] With the development of industry, the high-concentration refractory organic waste liquid discharged from pharmaceutical, chemical and other industries is increasing day by day. If it is discharged without treatment, it will cause serious pollution to the environment. The components of the waste liquid are usually: salt in a saturated state, some organic matter, and the rest is water. Although the traditional treatment technology can effectively remove COD, N, P and other pollutants in the waste liquid, it consumes a lot of energy and resources during the treatment process. In addition, a large amount of residual sludge will be produced. It can be seen that this waste liquid treatment method is not only time-consuming and i...
