A kind of for on-the-spot Chemical cleaning and blowdown acid-base neutralization integrated apparatus
Technical field
The utility model belongs to Chemical cleaning water technical field, particularly a kind of for on-the-spot Chemical cleaning and blowdown acid-base neutralization integrated apparatus.
Background technology
The Chemical cleaning of boiler, be to keep the heating surface inner surface clean, prevents that heating surface from causing accident because of fouling, corrosion, reduces the burning cost simultaneously, improves one of requisite measure of water and steam quality.
Boiler Chemical comprises the Chemical cleaning of capital construction boiler and boiler operation.Capital construction Boiler Chemical purpose is to remove corrosion product, welding slag and the silt pollution thing etc. that high-temperature oxydation that boiler forms in rolling, process rolls skin and depositing, producing in transportation, installation process; Operation stove Chemical cleaning purpose is to remove in boiler running process iron oxide dirt that heating surface gathers, calcium magnesium incrustation scale, copper dirt, silicate scale etc.
Power station heat power equipment Chemical cleaning mainly comprises the processing steps such as water flushing, alkali cleaning, rinsing, passivation and neutralization, contains the chemical substances such as acid, alkali, salt, complexing agent, passivator, surfactant in the cleansing medium of use.In Process of Chemical Cleaning, clean compound and other inorganic ionic compound of lower grease, mineral oil, high polymer, phosphoric acid salt crust sulfate scale, silicate scale, iron and copper from being cleaned equipment.When condenser and the cleaning of recirculated water cooling water tower, also have the dirts such as biological clay and suspension.These all enter in cleaning fluid, form the waste liquid that contains multiple pollutant matter.If these waste liquids, without dealing carefully with direct discharge, will inevitably cause ill effect to ecological environment, also directly have influence on our working environment and living environment.
After the station boiler Chemical cleaning, adopt after traditional Chemical cleaning waste liquid because can not meet environmental protection, energy-conservation requirement is restricted day by day, the station boiler Chemical cleaning that recommend now widely used " heat power plant boiler Chemical cleaning guide rule " (DL/T794-2001) (hereinafter to be referred as cleaning) passivation technology ubiquity waste liquid temperature is high, in and the problem such as the time is long, even some waste liquids are originally as carcinogenic substance, and environmental issue is outstanding; Therefore necessary exploitation is a kind of new for on-the-spot Chemical cleaning and blowdown acid-base neutralization integrated apparatus.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of for on-the-spot Chemical cleaning and blowdown acid-base neutralization integrated apparatus.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of for on-the-spot Chemical cleaning and blowdown acid-base neutralization integrated apparatus, comprise water tank and boiler, described water tank is equipped with particle contaminant filter barrier case by being connected in series successively in its right side wall bottom, the water pumping switch valve, the pipeline of inserting water valve under suction pump and water tank is connected with boiler bottom, form and clean the oral siphon road, described boiler bottom is connected with tank top by the pipeline that the underlying draining valve is installed, form the underlying water return loop, setting pressure table on the pipeline between described water pumping switch valve and suction pump, top left side at described water tank has water inlet, settle motor at tank top outer side center place, motor shaft extends to the water tank bottom apart from water tank bottom 20-30cm place through tank top straight down, low side at motor shaft is equipped with agitation blades, by pipeline, blowoff valve is installed in water tank right side wall bottom.
And the Plane of rotation that the rotation of described agitation blades bottom forms and the distance between water tank bottom are 20-30cm.
And the top of described boiler is connected with tank top by the pipeline of putting draining valve on being equipped with, forms and separately put on the way water return loop.
And, the water side on described suction pump right side and on put and be connected another road on the pipeline between draining valve and boiler the pipeline of inserting water valve is installed, formation is separately inserted water loop on the way.
Advantage of the present utility model and good effect are
The utility model has realized that Chemical cleaning, waste liquid are comprehensive, scrape the mud integrated treatment, has greatly shortened the Process of Chemical Cleaning time of boiler, has effectively alleviated the pollution problem of cleaning waste liquid.
The accompanying drawing explanation
Fig. 1 is the utility model device overall structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of for on-the-spot Chemical cleaning and blowdown acid-base neutralization integrated apparatus, as shown in Figure 1, comprise water tank 1 and boiler 5, described water tank is equipped with particle contaminant filter barrier case 12 by being connected in series successively in its right side wall bottom, water pumping switch valve 10, the pipeline of inserting water valve 6 under suction pump 8 and water tank is connected with boiler bottom, form and clean the oral siphon road, described boiler bottom is connected with tank top by the pipeline that underlying draining valve 3 is installed, form the underlying water return loop, setting pressure table 9 on the pipeline between described water pumping switch valve and suction pump, top left side at described water tank has water inlet 15, settle motor 2 at tank top outer side center place, motor shaft 14 extends to the water tank bottom apart from water tank bottom 20-30cm place through tank top straight down, low side at motor shaft is equipped with agitation blades 13, by pipeline, blowoff valve 11 is installed in water tank right side wall bottom.
In concrete enforcement of the present utility model, the Plane of rotation that the rotation of described agitation blades bottom forms and the distance between water tank bottom are 20-30cm.
In concrete enforcement of the present utility model, the top of described boiler is connected with tank top by the pipeline of putting draining valve 4 on being equipped with, forms and separately puts on the way water return loop.
In concrete enforcement of the present utility model, the water side on described suction pump right side and on put and be connected another road on the pipeline between draining valve and boiler the pipeline of inserting water valve 7 is installed, formation is separately inserted water loop on the way.
Operation principle
At first acidic cleaning solution is injected to water tank, start into water and water return loop boiler is cleaned, after cleaning end, by entering import, in water tank, add alkaline neutralising fluid, starter motor stirs neutralization by agitation blades, until the liquid in water tank is neutral.Simultaneously, along with the chemical reaction of N-process, will produce a large amount of sediment Direct precipitations in liquid in water tank bottom, reduce the directly externally discharge of pollutant.
