Abstract
The invention discloses a dust absorbing device for a storage hopper in wet powdered activated carbon dosing equipment. In the invention, by means of suction of an induced draft fan, the dust generated in the storage hopper while dosing enters an absorption trough via a dust collecting pipe with air and then the dust is absorbed by water, and the part of the dust absorbed by water and water form mixed liquid of powdered activated carbon and water; and when the density of the powdered activated carbon in the mixed liquid reaches the dosing requirement, an air release valve can be opened to discharge the mixed liquid from a blow-down pipe, and then the powdered activated carbon can be dosed to a process dosage point where the activated carbon is required. The dust absorbing device can eliminate dust pollution generated in the storage hopper while dosing and realize reutilization of the collected dust, thus saving the powdered activated carbon; and the dust absorbing device has low invested and operating cost, reliable operation and simple and convenient operation.
Description
Technical field
The present invention relates to a kind of dust absorption unit, this device is used for absorbing the dust that Powdered Activated Carbon wet type adding equipment feed bin is produced when charging.
Background technology
The drinking water source of China pollutes and is on the rise, and the organism kinds in the water source is many, in water treatment procedure, adds charcoal absorption usually and removes impurity such as organism in the former water.Because the specific surface area of Powdered Activated Carbon is big, therefore have very strong adsorptivity, can effectively remove colourity, turbidity and the peculiar smell of former water, effectively reduce the pollutant load in the former water.
The dosing method of Powdered Activated Carbon adopts the wet type dosing method usually, after being about to Powdered Activated Carbon and water mixing, drops in the former water by the mixed solution of volume pump with Powdered Activated Carbon and water again.
Feed bin in the Powdered Activated Carbon wet type adding equipment is positioned at the upstream of whole plant, and its purposes is the storage powder gac.The top of feed bin is typically provided with the opening that communicates with ambient atmosphere, so that the feed bin internal pressure keeps constant, guarantees that Powdered Activated Carbon can successfully join in the feed bin and successfully provides from feed bin.But Powdered Activated Carbon can produce a large amount of airborne dusts in the process that adds feed bin, just because of this opening at feed bin top, make airborne dust run out of feed bin easily, surrounding environment is caused serious dust pollution, not only endanger health of operators, also caused the waste of Powdered Activated Carbon.So there is the dealer to install fly-ash separator at this opening part, with the minimizing dust pollution, but this has increased complicacy, input cost and the running cost of equipment.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides the dust absorption unit of feed bin in a kind of Powdered Activated Carbon wet type adding equipment, this device can solve feed bin caused dust pollution when charging, and device drops into and running cost is low, reliable, easy and simple to handle.
The present invention for the technical scheme that solves its technical problem and adopt is:
The dust absorption unit of feed bin in a kind of Powdered Activated Carbon wet type adding equipment, the feed bin top is provided with venting port, dust leg one end is communicated with described venting port, be provided with the absorption cell of sealing, absorption cell top is communicated with water service pipe, described water service pipe is provided with feedwater valve, current in described feedwater valve its place pipeline capable of blocking are logical, the described dust leg the other end stretches in the interior liquid of absorption cell, the absorption cell upper end is provided with induced draft fan, there is fore-and-aft distance between the liquid level in induced draft fan and the absorption cell, this fore-and-aft distance is enough to guarantee that the liquid in the absorption cell is not inhaled in the induced draft fan, described absorption cell bottom is communicated with blow-down pipe, and described blow-down pipe is provided with blow-off valve, the liquid communication in described blow-off valve its place pipeline capable of blocking.
Further technical scheme of the present invention is:
Described absorption cell is divided into horizontal section and first, two vertical sections, the two ends of described horizontal section are respectively with first, two vertical sections one communicate, described horizontal section and first, two vertical sections make described absorption cell be the class U-shaped, the described dust leg the other end from first vertically the section upper end stretch into the liquid in the absorption cell, described induced draft fan is installed in the described second vertical section upper end, the position of a little higher than described horizontal section of the described second vertical section is provided with overflow port, described overflow port is communicated with upflow tube, described upflow tube is provided with surplus valve, liquid communication in described surplus valve its place pipeline capable of blocking, have fore-and-aft distance between the described second vertical section upper end and described overflow port, this fore-and-aft distance is enough to guarantee that the liquid in the absorption cell is not inhaled in the induced draft fan.
The invention has the beneficial effects as follows: the dust absorption unit of feed bin is by the suction of induced draft fan in this Powdered Activated Carbon wet type adding equipment, the dust that feed bin is produced when charging is entered in the absorption cell by dust leg with air and is absorbed by water, this part dust that is absorbed by water and water form the mixed solution of Powdered Activated Carbon and water, when reaching, the concentration of Powdered Activated Carbon in the mixed solution adds when requiring, can open blow-off valve, mixed solution is emitted from blow-down pipe, and can add the technology that adds gac to needs and add a little, this device has not only solved feed bin caused dust pollution when charging, and the dust of collection is reused, saved Powdered Activated Carbon, again and device drops into and running cost is low, reliable, easy and simple to handle.
