Abstract
The invention provides a process method for removing dust in waste gas, and relates to a method for removing dust from waste gas. The process comprises the following steps: directly introducing waste gas into a gas-liquid contact system or blowing the waste gas into the gas-liquid contact system by a blower, performing gas-liquid contact with water sprayed from a liquid distributor, adsorbing dust with water, and exhausting gas in a purified gas mode; collecting the liquid (water) after dust is absorbed by using a liquid collector, and freely flowing into a distributor, then flowing into a tilted plate sedimentation solid-liquid separation system, and regularly discharging sludge at the bottom of a tilted plate from the lower part of the tilted plate; causing the supernatant phase at the upper side of the tilted plate to enter into a circulating water system in an overflow manner, and feeding into a liquid distributor by a circulating pump to realize circulation. The system needs to regularly feed water to the circulating water system due to regular discharge of sludge, moisture distillation and loss and other reasons. The method is simple and convenient to operate, the removal rate of dust in waste gas can be over 99 percent, the treatment cost is advantageous, and a new means is provided for removal of dust in waste gas.
Description
Technical field
The present invention relates to dusty gas field of purification, be specially a kind of process of utilizing the mode of water circulation to remove dust in waste gas.
Background technology
Dust in discharging waste gas is one of main source of dust in atmosphere.Airborne dust is directly related with air quality, and dust affects our living environment, brings series harm.Follow now the multiple of haze weather, removing dust in air has become the mankind and has improved a generally requirement of environment.And directly start with from source, removing dust in waste gas is a mode of effecting a permanent cure.
In existing udst separation technology, more employing have processing methods such as cyclone water-film, static, filter membrane, water-bath, activated carbon filtration absorption, photocatalyst purification, ultraviolet ray and ozone sterilization, technique, equipment complexity that these processing modes are related, application cost and operating cost are higher.
Summary of the invention
In technical problem to be solved by this invention be: provide and from waste gas, remove dust, it is a kind of method that water absorbs dust control gas, can effectively remove dust, meet the requirement of toxic emission, for the dust, the improvement haze weather that effectively reduce atmosphere provide a new approach.
In order to overcome the deficiencies in the prior art, the technical solution adopted in the present invention is: the process of removing dust in waste gas, it is a kind of method of utilizing water circulation to absorb dust in waste gas, the described process of utilizing water circulation to absorb dust in removal waste gas body is made up of five links such as air-blowing, spray, sedimentation, blowdown, backwater, referring to accompanying drawing 1,2.Concrete steps are:
The first step, water absorbs dust in waste gas, discharges Purge gas.
Waste gas is direct or blast gas-liquid contact system by air blast, carries out gas-liquid contact with the water spraying through liquid distribution trough, and dust is adsorbed with water, and gas is discharged with the form of purified gas.
Second step, the collection and treatment of dust, the recycling of water.
The liquid (water) absorbing after dust is collected by liquid header and through from flowing to distributor, then flows to inclined plate sedimentation solid-liquid separation system, and the mud of swash plate bottom, regularly discharges from bottom; The clear liquid phase overflow of swash plate upside enters circulation, sends into liquid distribution trough by circulating pump, realizes circulation.Wherein, because of the regular discharge of mud, the reasons such as moisture evaporation and loss, system needs regularly to circulation moisturizing.
Above-mentioned a kind of process of removing dust in waste gas.
Above-mentioned a kind of process of removing dust in waste gas, described water is middle water, running water or underground water etc.
Above-mentioned a kind of process of removing dust in waste gas, described gas-liquid contact system comprises liquid distribution trough, gas-liquid contact part, liquid recovery device and gas blow-off system.
Above-mentioned a kind of process of removing dust in waste gas, gas-liquid contact system, inclined plate sedimentation solid-liquid separation system, return water system and spray system used all easily obtain by known approach, and described technique is that those skilled in the art is known.
Flow process of the present invention is simple, and the dust that only need remove in waste gas body by simple step gets final product Purge gas; The present invention is easy and simple to handle, and in waste gas body, the clearance of dust can reach more than 99%, and processing cost has advantage, for the dust of removing in waste gas provides a new approach.
