This utility model belongs to energy-saving equipment field, especially a kind of pickling line acid mist reclaiming clean equipment.
Background technology
Current China cold-rolling pickling production line has hundreds of bar, no matter the sector is continuous acid-washing or plug-type pickling, its acid cleaning process is all first by hydrochloric acid to 18%��20% concentration, reheat the temperature needed for acid cleaning process, it is circulated flowing by circulating pump and makes the homogeneous temperature of acid, it is re-fed into descaling bath, carries out shallow slot turbulence acid dip strip steel. In this course along with the rising (75��85 DEG C) of acid liquor temperature, substantial amounts of HCL gas evaporates from descaling bath along with water vapour, produces substantial amounts of acid mist. This phenomenon according to my company experience for many years and variable interval to the former field conditions sampling Detection of client, acid mist concentration is between 7%��15%. Therefore the loss of hydrochloric acid and the purification of acid mist just become two hang-ups of puzzlement enterprise.
At present, the acid mist that acid cleaning process is produced by most of producers adopts the mode of purifying column washing that acid mist is carried out spray washing absorption, after absorption, sour water is directly sent to neutralisation treatment station and carries out acid-base neutralization, so both waste acid solution, waste again alkali raw material, (if carrying out process with lime cream to create substantial amounts of waste residue and cause secondary pollution), also environment is created negative effect, make unit cost production increase. Acid mist only carries out spray washing by purifying column simultaneously, is extremely difficult to country's discharge working standard.
The open a kind of acid mist reclaiming clean equipment of patent documentation 201728055U, including acid dip pickle, mist collector, purifying column, fog discharge blower fan, described acid dip pickle is connected with condenser, liquid drop separator, purifying column, fog discharge blower fan successively by mist collector; Described liquid drop separator is connected with acid dip pickle by acid storage tank.
The open a kind of acid mist washing and recycling purifier of patent documentation 201524514U, is constituted including horizontally disposed adsorbing separation pipeline and the spray discharge tower vertically set up, and the outlet of described adsorbing separation pipeline connects with the bottom inlet of spray discharge tower; It is characterized in that: be provided with separating mechanism in described adsorbing separation pipeline, this separating mechanism is then made up of the porous inserts being fixed in pipeline and the porous flat plate being arranged at both sides;Described spray discharge tower is disposed with the spraying mechanism that 2-4 group shower nozzle is downward, and the spraying mechanism that one to two group shower nozzles are upwards is constituted; The outlet of acid solution and mixed liquor it is respectively arranged with in the bottom of the bottom of adsorbing separation pipeline and spray discharge tower.

The technical scheme that this utility model realizes purpose is as follows:
A kind of acid regeneration acid mist reclaiming clean equipment, including acid mist absorbent assembly, mixing column, condensing tower, acid solution recycling can and air-introduced machine, the gas outlet connection of acid mist absorbent assembly connects the gas outlet of the bottom air inlet connection roaster of mixing column, the gas outlet, top of mixing column connects the bottom air inlet of condensing tower, and the gas outlet, top of condensing tower connects air-introduced machine; The structure of described acid mist absorbent assembly, for including a horizontal acid mist extraction duct, is provided with multiple acid mist and absorbs mouth at the interval, bottom of acid mist extraction duct, absorbs at acid mist and installs filter element in mouth; Described mixing column is acid mist water smoke mixing column, water smoke eruption assembly is installed on the top of mixing column, the mist section of entering of water smoke eruption assembly is fastened on the nebulizer of mixing column, condensing fin assembly is installed in described condensing tower, the connection of condensing fin assembly connects refrigeration unit, after cooling, liquid drips downward into acid solution collecting tank, is shaped with collecting tank in condensing tower bottom, and collecting tank connects acid solution recycling can by pipeline.
And, it being shaped with acid solution collecting tank in the tower bottom of described mixing column, this acid solution collecting tank passes through pipeline communication acid solution recycling can.
The beneficial effects of the utility model are:
The pickling line acid mist reclaiming clean equipment that this utility model provides is firstly introduced nebulizer in mixing column, carry out cooling after acid mist and water smoke being mixed to absorb, acid mist can be reclaimed on the one hand, acid mist can be lowered the temperature on the other hand, play dual effect, improve purification efficiency.
The configured in one piece of the pickling line acid mist reclaiming clean equipment that this utility model provides is simple, and operating process is smooth and easy, and restored acid liquid can recycle, environmental protection.
Accompanying drawing explanation
Fig. 1 is this utility model heat pipe flue gas waste heat recovery apparatus (broken section);
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following example are illustrative, are not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of pickling line acid mist reclaiming clean equipment, including acid mist absorbent assembly, mixing column 2, condensing tower 6, acid solution recycling can 9 and air-introduced machine 8, the gas outlet connection of acid mist absorbent assembly connects the gas outlet of the bottom air inlet connection roaster of mixing column, the gas outlet, top of mixing column connects the bottom air inlet of condensing tower, the gas outlet, top of condensing tower connects air-introduced machine, air-introduced machine provides acid solution in intrasystem operation captivation, and after purifying, qualified air is removed in air.
The structure of described acid mist absorbent assembly is for including a horizontal acid mist extraction duct 1, multiple acid mist is installed at the interval, bottom of acid mist extraction duct and absorbs mouth 1-1, absorb at acid mist and filter element 1-2 is installed in mouth, for filtering the impurity absorbed in the acid mist come in, it is ensured that the function smoothly of whole pipeline.
