Description

Waste gas treatment process
Technical field
The invention belongs to technical field of waste gas treatment, and in particular to a kind of waste gas treatment process.
Background technology
Enterprise's waste gas is major source of pollutant, and manufacturing enterprise is perplexed in its processing always.Especially as society development, country and People increasingly pay attention to environmental pollution, environmental improvement.Therefore, the processing of enterprise's waste gas is urgent problem.
The content of the invention
The purpose of the present invention is to propose to a kind of waste gas treatment process, and its technique is simple, easy to use, and cost is low, at waste gas Efficiency high is managed, low exhaust gas emission is dropped, reduces environmental pollution, meet market use demand, be advantageous to the popularization of product.
In order to reach above-mentioned purpose of design, the technical solution adopted by the present invention is as follows:
A kind of waste gas treatment process, waste gas are collected by collection conduit and are delivered to cyclone dust collectors, carry out dust removal process, with Enter two-stage exhaust-gas treatment afterwards;First, waste gas first passes through spray column, by water pump shower water, most organic matter and dust Attach in water, UV photodissociation purified treatments are carried out again after the discharge of a small amount of organic exhaust gas.
Preferably, the waste gas treatment process, comprises the following steps:
Step 1: gas sampling and conveying, the waste gas that enterprise produces is collected by pressure fan, and carried out by pipeline defeated Send;
Step 2: waste gas coagulation, is sent to cyclone dust collectors by waste gas, carries out coagulation, its process is:In waste gas Dust rotate, grit is separated from air-flow by means of centrifugal force and is trapped in wall, then is made by Action of Gravity Field Grit falls into ash bucket;
Step 3: waste gas two stage treatment, is transported to spray column by seal for pipe joints by the waste gas that cyclone dust collectors come out, enters Row two stage treatment, its process are:Waste gas introduces purifying column by airduct, and by packing layer, waste gas carries out gas-liquid two-phase with absorbing liquid Fully contact absorbing reaction, waste gas are discharged after purification, then after demisting plate dehydrating demisting by blower fan, and absorbing liquid passes through in bottom of towe Water pump supercharging after tower top spray and under, be finally back to bottom of towe recycling;
Step 4: waste gas tertiary treatment, is transported to UV photodissociation equipment by seal for pipe joints by the waste gas that spray column comes out, enters Row tertiary treatment, its process are:The oxygen molecule decomposed using high energy high ozone UV ultraviolet beams in air produces free oxygen, i.e., It active oxygen, need to be combined because free oxygen is unstable with oxygen molecule, and then produce ozone;UV+O2 → O-+O* (active oxygen) O+O2 → O3 (ozone), Pre-Ozonation on Organic Matter has extremely strong oxidation, so that waste gas is purified, is pumped finally by air-introduced machine To discharge tube qualified discharge;
Step 5: exhaust, the waste gas after the tertiary treatment of step 4, is discharged through blower fan.
The spray column of the step 2, circular water treating system is equipped with, is specially:The waste water of spray column enters recirculated water Pond, the water in circulating water pool sequentially enter three reaction tanks, are reacted, subsequently into sedimentation basin, precipitated, after precipitation Water enters clear water reserviors, and clear water reserviors unidirectionally communicate with circulating water pool so that the water in clear water reserviors enters circulating water pool.
The beneficial effect of waste gas treatment process of the present invention is:Its technique is simple, easy to use, and cost is low, waste gas Treatment effeciency is high, drops low exhaust gas emission, reduces environmental pollution, meet market use demand, be advantageous to the popularization of product.
Brief description of the drawings
Fig. 1 is the schematic diagram of waste gas treatment process of the present invention.
Embodiment
Preferred embodiment of the invention is described in further detail below.
As shown in figure 1, waste gas treatment process of the present invention, waste gas is collected by collection conduit and is delivered to cyclone dust removal Device, dust removal process is carried out, subsequently enters two-stage exhaust-gas treatment;First, waste gas first passes through spray column, by water pump shower water, greatly Partial organic matter and dust is attached in water, and UV photodissociation purified treatments are carried out again after the discharge of a small amount of organic exhaust gas.
Specifically include following steps:
Step 1: gas sampling and conveying, the waste gas that enterprise produces is collected by pressure fan, and carried out by pipeline defeated Send;
Step 2: waste gas coagulation, is sent to cyclone dust collectors by waste gas, carries out coagulation, its process is:In waste gas Dust rotate, grit is separated from air-flow by means of centrifugal force and is trapped in wall, then is made by Action of Gravity Field Grit falls into ash bucket;
Step 3: waste gas two stage treatment, is transported to spray column by seal for pipe joints by the waste gas that cyclone dust collectors come out, enters Row two stage treatment, its process are:Waste gas introduces purifying column by airduct, and by packing layer, waste gas carries out gas-liquid two-phase with absorbing liquid Fully contact absorbing reaction, waste gas are discharged after purification, then after demisting plate dehydrating demisting by blower fan, and absorbing liquid passes through in bottom of towe Water pump supercharging after tower top spray and under, be finally back to bottom of towe recycling;
Step 4: waste gas tertiary treatment, is transported to UV photodissociation equipment by seal for pipe joints by the waste gas that spray column comes out, enters Row tertiary treatment, its process are:The oxygen molecule decomposed using high energy high ozone UV ultraviolet beams in air produces free oxygen, i.e., It active oxygen, need to be combined because free oxygen is unstable with oxygen molecule, and then produce ozone;UV+O2 → O-+O* (active oxygen) O+O2 → O3 (ozone), Pre-Ozonation on Organic Matter has extremely strong oxidation, so that waste gas is purified, is pumped finally by air-introduced machine To discharge tube qualified discharge;
Step 5: exhaust, the waste gas after the tertiary treatment of step 4, is discharged through blower fan.
The spray column of the step 2, circular water treating system is equipped with, is specially:The waste water of spray column enters recirculated water Pond, the water in circulating water pool sequentially enter three reaction tanks, are reacted, subsequently into sedimentation basin, precipitated, after precipitation Water enters clear water reserviors, and clear water reserviors unidirectionally communicate with circulating water pool so that the water in clear water reserviors enters circulating water pool.
