Description
Technical field
The utility model relates to a kind of scrubber that is applied in the sludge treating system, refers more particularly to the scrubber that adopts Venturi tube.
Background technology
Along with the raising of China's economic construction high speed development and people's environmental consciousness, the sewage treatment plant of all kinds and scale builds up one after another, and country has also worked out comparatively strict feasible standard to the discharging of all kinds of sewage disposals.Yet, to the isolated polluter of sewage treatment plant---the processing of mud does not but cause enough attention.Most of water treatment plant is to containing the mud of various harmful substances, the ways that adopt directly discharging, are used for agricultural fertilizer and landfill cause secondary pollution to environment more, and health is caused metastatic harm, greatly weaken the positive role of sewage treatment plant's purification of water quality, cause massive losses economically.
In sludge handling process, affect sludge quality stable be organic matter amount in the mud, these organic matters contain a large amount of unsettled extractions of humic substances, extremely unstable, will distribute niff at short notice, therefore need to carry out stabilization processes, the residue after final dehydrated sludge cake or the burning also needs further disposal.The sludge quantity that the municipal sewage plant produces is relevant with each country, each regional sewage disposal load, processing method and sewage composition etc.
Therefore, need a kind of scrubber of design, the gas that produces in the sludge treating system process is washed and dedusting.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provide a kind of can to flue gas and dust washs and dedusting, and guarantee not produce any harmful substance and gas, satisfy the Venturi scrubbing deduster of flue gas qualified discharge.
The technical scheme that its technical problem that solves the utility model adopts is:
The Venturi scrubbing deduster, include blower fan and connecting pipe, it is characterized in that: also include Venturi scrubber, cyclone separator and dedusting washer, its pipeline order of connection is followed successively by blower fan-Venturi scrubber-cyclone separator-dedusting washer, wherein said Venturi scrubber includes the Venturi tube nozzle, described cyclone separator side is provided with Venturi tube and leads to the cyclone separator bottom, its top is provided with waste gas outlet, described dedusting washer bottom also has air inlet, the top also is provided with waste gas outlet, and its top also has the cleaning solution import, also is provided with packing layer in the dedusting washer.
In such scheme, described Venturi scrubber is divided into up and down two parts, top is the Venturi tube nozzle, the bottom is liquid holding cavity, and separator is housed in the liquid holding cavity, and Venturi tube nozzle top is the cleaning solution inlet port, the side is the waste gas inlet port, cleaning solution and waste gas abundant mixing jetting in the Venturi tube nozzle enters separator, and the gas after the isolation of purified is got rid of from the other gas vent of liquid holding cavity, and liquid then is stored in the liquid holding cavity.
In such scheme, described cyclone separator is tower structure, and its bottom also is provided with the waste liquid outlet.
In such scheme, described dedusting washer also is tower structure, and its bottom also is provided with the waste liquid outlet.
The injecting type Venturi scrubber is to solve one of most economical method of ever-increasing air pollution problems inherent.Cleaning solution sprays from nozzle, forms the taper spray of hollow.Cleaning solution and contaminated gas are in contact with one another and carry out a large amount of mass exchange and catch particle in the gas, and mixture is discharged to separator.It is used for reducing smog and the peculiar smell of emission gases, cleans and purifies air, and reclaims valuable but is originally discharged in vain the effective ways of product.The injecting type Venturi scrubber also can be used as inspissator, and method is that absorption liquid constantly circulates until till the required concentration as motive fluid.Because do not have moving component and under the low speed operation, the injecting type Venturi scrubber only needs maintenance and maintenance seldom.The injecting type Venturi scrubber use liquid as the power of injector to carry dusty gas, therefore-as do not need air blast to carry to need to process gas.Relatively high liquid-gas ratio and liquid mist rate, and inner open by design is effectively washed the gas that is heavily polluted.
The dedusting washer has used vertical reverse flow design, can very effectively absorb various toxic gases.Except the extensive use aspect the air pollution control, the dedusting washer also can be used for various technical process as gas-liquid contactor.99. the detersive efficiency more than 99% is common in many gas scrubbings are used.In operation, gas upwards flows through packing layer, and cleaning solution is under Action of Gravity Field simultaneously, and along packing layer toward dirty, the reverse flow design principle provides the optimisation substance transmission.
The most suitable particulate of catching less than 3 microns of cyclone separator, it is effective too to submicron-sized particulate.The high velocity air that is full of dust is used to the cleaning solution that atomizes, and in separator, the liquid that carries full dust in the spiralling air-flow is thrown to outer wall under the effect of centrifugal force, deliver to cesspool after liquid is collected.Cyclone separator needs maintenance hardly, in the vicissitudinous situation of gas flow, need to compensate to the speed that gas flow is crossed trunnion to keep the detersive efficiency be scheduled to, can provide automatically and manual two kinds of variable venturis design.Automatically the control trunnion is designed for the gas flow variation greatly, use under the condition that needs often to adjust.When variation just occurs once in a while, available manual control trunnion design.
The beneficial effects of the utility model are: can to flue gas and dust wash and dedusting, and guarantee not produce any harmful substance and gas, satisfy the Venturi scrubbing deduster of flue gas qualified discharge.Simultaneously, the hydrogen chloride in the waste gas of collection has been produced the hydrochloric acid solution that can sell simultaneously, has certain economic benefit.
