Description
Technical field
The present invention relates to emission-control equipment field, more particularly to a kind of low-concentration organic exhaust gas recovery and processing system.
Background technology
The technology of domestic treatment organic exhaust gas is divided into two major classes from principle at present：Reclaim and decompose.Recovery process is main
It is that, with charcoal absorption, then by alternating temperature, the mode of transformation is desorbed, and reuse is condensed after desorption.This kind of recovery technology is directed to
Small air quantity, the waste gas of middle and high concentration has recovering effect higher, is widely used.But it is directed to large-wind-volume low-concentration and has
The organic exhaust gas of higher reclamation value can not but be applied well, main reasons is that air quantity is too big, cause the capital cost of equipment
With very high, floor space is very big, and operating cost also can be very high in addition, without feasibility economically.Other traditional activity
Charcoal adsorption recovery system is due to charcoal absorption limited efficacy, if the exhaust gas concentration of front end instantaneously increases, such as fixed gas return air, life
Produce discharge capacity and increase etc., these situations can all cause the exhaust-gas treatment can not to reach existing discharge standard.
Generally, recyclable organic exhaust gas (middle and high concentration) will first be processed by pre-processing device, reach removal
The purpose of particulate matter, soda acid waste gas and cooling.Enter charcoal absorption desorption column, absorption by pretreated organic exhaust gas
Tower using multitower parallel connection by the way of, the waste gas qualified discharge for having adsorbed.The activated carbon adsorber of adsorption saturation is carried out using steam
Regeneration, when normal operation, the activated carbon that can at least meet has an activated carbon adsorber after regenerative operation, regeneration is inhaled
Attached tower is transferred to adsorption cycle, such cyclic switching again after drying cooling.The quantity and size of tower need air quantity according to waste gas,
Concentration is determined.
Using steam heating desorption (alternating temperature principle), the mixture of desorption organic steam out and vapor leads to again for regeneration
Cross condenser to be condensed, the temperature of cooling water is fixed according to different organic principles.It is condensed into the organic principle and liquid of liquid
Water is separated into special separating barrel, and again by rectifying reuse, sewage enters sewage network to the organic principle after separation, enters
Enter next step treatment.The principle being desorbed by charcoal absorption, realizes the recycling of organic principle in waste gas, reaches waste gas
Treatment and the good combination for reclaiming, realize good economic benefit.This be in the market in most common waste gas it is organic into
Divide recovery process.
The cooling water temperature that heat exchanger is used typically uses normal-temperature water or salt solution, and chilling temperature is limited, according to it is organic into
The saturated vapour pressure data divided, still have substantial amounts of organic principle to exist in a gaseous form, i.e. fixed gas after cooling.Fixed gas leads to
Crossing pipeline and being re-introduced into activated carbon adsorber front end carries out adsorption treatment again, and this part air quantity is smaller, but dense typically exists
Every cube or so of tens of thousands of milligrams, this can also increase the load of activated carbon adsorber, cause charcoal absorption to process not up to standard.Separately
Outward, many production technologies are unstable, and in extreme circumstances, the exhaust gas concentration that certain a period of time excludes can be inhaled more than activated carbon
The adsorption treatment ability of attached tower, in turn results in exhaust-gas treatment not up to standard.
It can be seen that, the shortcoming of existing mainstream technology mainly has at 2 points：
1st, it is not suitable for the organic exhaust gas for having recovery value of large-wind-volume low-concentration, main reasons is that air quantity is too big, leads
The investment cost of cause equipment is very high, and floor space is very big, and operating cost also can be very high in addition, without feasibility economically.
2nd, traditional in addition charcoal absorption recovery system due to charcoal absorption limited efficacy, if the exhaust gas concentration of front end
Instantaneously increase, such as fixed gas return air, production discharge capacity increases etc., these situations can all cause the exhaust-gas treatment can not to reach existing row
Put standard.
