Description
Technical field
The utility model relates to wet cottrell technical field, specially a kind of wet type with spray washing function
Electrostatic precipitator.
Background technique
Wet flue gas dust separation technology is the technology being most widely used.For dedusting, be capable of handling high temperature, high humidity,
Large viscosity and gas containing high resistivity dust, processing is flammable, explosive gas or when dust, can by kindling, explosion can
It can reduce to minimum.Liquid or the solid particles that diameter is 0.1~20 μm can be effectively removed, gaseous pollutant can be also removed.
And counter current contacting spray purification tower is the mainstream tower of wet flue gas dedusting and purifying device, belongs to low energy wet dust removal
Device.In, tower few with internal component it is less scaling with blocking, the pressure loss is small, operating cost is low, performance is stable, easy to operate
The advantages that.The usual pressure loss is 0.2~2.5kPa, and the cleaning harmful gas process such as flue gas ash removal and desulfurization is widely applied.
Counter current contacting spray purification tower is used for dedusting, is that inertial collision, interception function, diffusion effect, thermophoresis and electrostatic are made
With etc. the process realized jointly of a variety of effects, wherein inertial collision and interception function are the main dedusting mechanism of wet scrubber.
When trapping the grit of very little, the influence of diffusion caused by Brownian movement will receive.Inertial collision effect mainly takes in tower
Certainly in grit quality and its speed of related movement between water droplet；There is important relationship with drop size simultaneously.In general water
It drips hour, inertial collision effect enhancing is conducive to separate grit from dusty gas.So being wanted for given dust-laden system
Improve the quasi- number St value of Stokes, it is necessary to improve the speed of related movement between gas-liquid and reduce drop diameter.In amount of water sprayed one
Periodically, water droplet is thinner, and the ratio that decline water droplet is covered with tower section is bigger, and the probability for generating interception trapping grit is bigger.
But counter current contacting spray purification tower is used for dust removal process, and drop diameter is not smaller better, the sedimentation speed of fine water droplet
Degree is slower, or even the phenomenon that too small water droplet of diameter is moved with air-flow, the relative motion between fine water droplet and gas occurs
Speed is smaller than thick water droplet, thus reduces by the probability of inertial collision trapping grit with drop diameter and reduce, and is unfavorable for from dust-laden
Grit is separated in gas, while increasing the gas-liquid separation difficulty of flue gas after purification.Therefore drop diameter will be by water droplet
Landing time in tower and the limitation being entrained by the flow of air.
Conventional counter-current contacts spray purification tower for cleaning harmful gas processes such as flue gas desulfurizations, equally exists absorbent mist
Change partial size is too big, and absorbent utilization rate is low, too small to be easy to carry out scrubbing section by flue gas, and the desulfurizing agent not reacted completely is caused to damage
It loses, increases load to equipment such as technique back segment demisters.The atomizing particle size of usual wet desulphurization is at 1300--3000 μm.And foundation
Boundary-layer theory strengthens mass transfer measure mainly by good atomization, generates tiny drop, while increasing relative motion speed
Degree.
Wet purifier causes flue gas to enter in tower to enter after rising in spraying layer using unilateral horizontal access intake method
Flow Field Distribution bias current is serious at mouthful, be easy to cause tower wall flue gas short-circuit, and flue gas is exported from absorption tower without spraying layer and escaped, so that
The efficiency of dust collection deficiency of the device far can not reach the requirement of minimum discharge, and flue gas ash when carrying out depositing dust is easy accumulation, no
Convenient for removing, it is based on this, the utility model devises a kind of wet cottrell with spray washing function, on solving
State problem.
