Embodiment 1

[0053] The acid waste gas containing HCl and H2S enters the reactor with filler A and filler B through the pipeline, and is fully mixed with the alkaline aqueous solution containing NaOH sprayed from the top of the reactor, and the acid-base neutralization reaction occurs on the surface of the filler to become neutral . The remaining alkaline aqueous solution that descends to the bottom of the reactor becomes thinner due to the consumption of alkali, which can be supplemented with alkali for recycling. The neutral gas from the reactor can meet the standard and be directly discharged into the atmosphere.

Embodiment 2

[0055] The concentration of concentrated sulfuric acid used for product drying becomes thinner after use. After being heated to above 50°C, it is sprayed from the top of the evaporator. The easily evaporated water evaporates on the surface of the packing and is taken out of the evaporator by the wind. The sulfuric acid returns from the top of the packing to the bottom. Department, circulation treatment, sulfuric acid concentration becomes concentrated.

Embodiment 3

[0057] The low-concentration medicinal solution dissolved and extracted is heated and controlled below 50°C to avoid deterioration of heat-sensitive drugs. It is sprayed from the top of the evaporator, and the water or solvent in the medicinal solution evaporates on the surface of the filler and enters the air, which is continuously absorbed by the air. Take away, the liquid flowing to the bottom along the filler can be concentrated, and the concentrated solution after multiple cycles can be discharged from the bottom of the evaporator to form a finished product or a semi-finished product after reaching the concentration requirement.

[0058] The evaporator is as image 3 structure shown.

Abstract

The invention provides multifunctional filler, and further provides sewage treatment equipment utilizing the multifunctional filler. The multifunctional filler comprises a frame, the frame is internally provided with a plurality of connecting pieces from the upper top part to the lower bottom part, grooves are formed in the connecting places between the upper part of the frame and the connecting pieces as well as between the lower part of the frame and the connecting pieces, so that liquid flows to the lower portion along the connecting pieces, and the multiple connecting pieces are parallel;and during using, the connecting pieces are perpendicular to the ground. The multifunctional filler can be assembled into an evaporator and a condenser, so that low-temperature evaporation and high-efficiency condensation are achieved; and as long as the condition that the cooling temperature is lower than the evaporation temperature is met, evaporation and condensation between 5 DEG C and 100 DEGC can be realized. According to the multifunctional filler, the evaporator, the condenser and a reactor composed of the multifunctional filler can be connected in series through pipelines according to the need, so that multi-stage cyclic evaporation condensation or multi-stage cyclic gas absorption and reaction and the like are formed, and the evaporator, the condenser and the reactor can be usedfor sewage treatment, waste gas treatment, seawater desalination, concentration, separation and purification.

Description

technical field [0001] The invention belongs to the fields of environmental protection and chemical industry, and in particular relates to a multifunctional filler and an evaporator, a condenser and a reactor containing the multifunctional filler. Background technique [0002] At present, there are two main types of evaporation technologies widely used in the fields of environmental protection and chemical industry: multiple effect evaporation technology (Multiple Effect Distillation, abbreviated as MED) and vapor recompression evaporation treatment technology (Mechanical VaporRecompression, abbreviated as MVR). The MED process is to pass heating steam into an evaporator, and use the secondary steam generated by heating and boiling the solution as heating steam through indirect heat exchange, and introduce it into the next evaporator, and so on, the new secondary steam generated by the second evaporator The secondary steam can be used as the third evaporator as heating steam...
