Abstract
The invention discloses an adding equipment of a post-ozone air ejector. The adding equipment comprises an ozone generator, an ozone distribution pipeline and an ozone contact pool, wherein an aerating disc is installed at the bottom of the ozone contact pool, and the ozone gas enters into the aerating disc through the distribution pipeline; a bypass pipeline consisting of the air ejector is additionally arranged on the distribution pipeline, and one-off valves are respectively arranged on the distribution pipeline and the bypass pipeline; besides an ozone gas inlet, the air ejector further comprises a mixed gas inlet connected with an air blower; the mixed wind outlet of the air ejector is connected with the aerating disc through the distribution pipeline. The adding equipment disclosed by the invention can be used for solving the technical problem that a post-ozone adding system of a water plant has different demands on the ozone adding rate in different seasons and the operating cost is effectively lowered.
Description
Technical field
The invention belongs to municipal water supply processing technology field.
Background technology
Ozone and activated carbon technology in water-purifying process to removing micro-Organic Pollutants, reduce disinfection byproduct (DBP) and improvement and smell aspect the Oranoleptic indicators such as taste and play a significant role.Along with the deterioration increasingly of raw water quality and the progressively raising of Effluent criteria, ozone and activated carbon technology has broad application prospects at home.Ozonation system mainly comprises three parts such as source of the gas, ozone generation and ozone add.The specification of ozonizer generally adds rate by maximum and high day service discharge is determined.Ozone adds and is divided into pre-ozone and adds with rear ozone and add two kinds.Rear ozone dosage system comprises ozone gas distributing pipeline and ozone contact tank.Rear ozone contact tank available depth is generally 6m, and aeration plate is installed in bottom, and ozone gas enters aeration plate by gas distributing pipeline, then discharges from aeration plate in trickle bubble mode, fully mixes and reacts with water.
Most of northern area water factory, in the winter time with summer former water in organic content have bigger difference, it is lower that the ozone that need winter adds rate, the service discharge in winter of water factory is few in addition, required ozone dosage is lower, needs ozonizer to move under lower output.Taking Beijing water factory as example, the rear ozone that need summer adds rate up to 2mg/l, and the rear ozone that need winter adds rate only for 0.2mg/l, required rear ozone dosage two season of summer in winter difference very large.
Ozonizer and adding equipment are generally by maximum dosage type selecting, the output of ozonizer all can be adjusted in 10～100% scopes in theory, by the oxygen flow that enters ozonizer is regulated, in the time of ozonizer low yield, play the effect that reduces flow of oxygen reduction running cost.In fact for rear ozonation system aeration plate aeration evenly ensures the transfer efficiency of ozone in water, prevent that aeration plate from stopping up, most of ozone producer requires the tolerance in dosing system must reach certain value (30～40% design discharges).When northern area water factory moves in the winter time mostly, have to adopt the mode that strengthens oxygen air input, reduces ozone concn to be moved, ensure the minimum tolerance requirement of aeration plate, this mode has increased oxygen consumption, has improved running cost.
Summary of the invention
The object of this invention is to provide a kind of after ozone-air injector adding equipment, in different seasons, different ozone is added to the requirement of rate with the rear ozone dosage system that solves water factory, and the technical problem effectively cutting operating costs.
In order to realize foregoing invention object, the technical solution adopted in the present invention is as follows:
Ozone-air injector adding equipment after a kind of, comprises ozonizer, ozone gas distributing pipeline and ozone contact tank, in ozone contact tank bottom, aeration plate is installed, and ozone gas enters aeration plate by gas distributing pipeline; On described gas distributing pipeline, increase a by-pass line being formed by air-sprayer, on gas distributing pipeline and by-pass line, be respectively equipped with on-off valve, this air-sprayer is except having an ozone gas import, also have a mixed gas import being connected with gas blower, the mixed wind outlet of this air-sprayer is connected with aeration plate by gas distributing pipeline.
Advantage of the present invention is: exchange less energy-consumption operational conditions for few investment.Taking 10kg/h specification ozonizer system as example: when actual needs ozone dosage is during only as 1kg/h, by traditional method operation, more than ozonizer oxygen depletion amount must reach 40kg/h, ozone concn is less than 10%.While operation by the present invention, ozonizer oxygen depletion amount is only 10kg/h, ozone concn 10%, and now gas blower current consumption is 3.2 degree/h.Press 2800 yuan/ton of oxygen, 0.8 yuan/degree of the electricity charge calculates, and adopts after the present invention, and working cost is than originally reducing more than 90%.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure, number: 1. liquid oxygen tank, 2. vaporizer, 3. ozonizer, 4. gas distributing pipeline, 5. ozone contact tank, 6. air-sprayer, 7. gas blower, 8. ozone by-pass line.
Embodiment
Concrete structure of the present invention is referring to Fig. 1.This rear ozone-air injector adding equipment, comprises ozonizer 3, ozone gas distributing pipeline 4 and ozone contact tank 5, in ozone contact tank 5 bottoms, aeration plate is installed, and ozone gas enters aeration plate by gas distributing pipeline 4; On described gas distributing pipeline 4, increase a by-pass line being formed by air-sprayer 8, on gas distributing pipeline 4 and by-pass line 8, be respectively equipped with on-off valve, this air-sprayer 6 is except having an ozone gas import, also have a mixed gas import being connected with gas blower 7, the mixed wind outlet of this air-sprayer 6 is connected with aeration plate by gas distributing pipeline 4.
In the time that water factory winter, required ozone dosage was lower, start gas blower and air-sprayer, blower air quantity meets the requirement of ozone devices to the minimum tolerance of dosing system.Forced air and ozone gas enter ozone contact tank after air-sprayer internal mix, mix with water by discharging a large amount of microbubble continuously in aeration plate, ensure the assimilated efficiency of ozone in ozone contact tank, save oxygen consumption.
When water factory, required ozone dosage reaches certain value, and while making gas flow in rear ozone dosage system reach minimum tolerance, the operation of can turn off the blast machine and air-sprayer, recovers traditional dosing method.
