Description
Technical Field
The invention relates to a smoke abatement and temperature reduction device and a smoke abatement and temperature reduction process for a diesel generator set, and belongs to the technical field of tail gas treatment.
Background
The exhaust temperature of the diesel engine is generally as high as several hundred degrees centigrade, and some special places have strict requirements on the exhaust temperature, and the final exhaust temperature is required to be close to the external environment temperature. For example, a protection engineering underground power station uses a diesel generator (diesel engine for short) as a power source, the diesel generator emits more than 200 kinds of harmful gas and solid emissions when working, but mainly smoke and high-temperature gas which can expose engineering targets can be detected by shooting or far infrared rays, so that the research of the scheme is mainly to greatly reduce the concentration and temperature of black smoke emitted by the diesel generator, and the black smoke is discharged outside the engineering without exposing the targets.
There are many measures for purifying exhaust gas from diesel engines, and these measures are broadly classified into two main categories: one is to control the generation amount of pollutants in the combustion process before the fuel gas is discharged out of an exhaust valve and after the combustion process, namely, the control technology before the exhaust, or the technology of purifying in the engine; another type is to reduce the amount of pollutants that enter the atmosphere after the exhaust exits the exhaust valve, i.e., exhaust after-treatment techniques. At present, the post-treatment mode adopted for reducing the soot of the diesel engine at home and abroad is easy to cause exhaust blockage and increase the back pressure of the diesel engine.
The particulate trap (DPF) is the most common technology for solving the diesel engine particulate matter emission effectively at present, and can reach the capture effect of Particulate Matter (PM) more than 90%, but along with the increase of operating time, the filter core lateral wall particulate matter is constantly attached to, leads to the exhaust backpressure to constantly rise, and this has seriously influenced the economic nature of the dynamic nature of diesel engine. Cleaning particulate matter in a DPF is referred to as DPF regeneration, and current regeneration methods include two major types, active regeneration and passive regeneration. The active regeneration method comprises oil injection regeneration, electric heating regeneration, infrared regeneration, microwave regeneration, back flushing regeneration and the like, and the active regeneration method has the defects of complex structure and consumption of other energy, such as consumption of additional fuel oil for oil injection regeneration, consumption of electric energy for electric heating regeneration, and consumption of radiation energy for infrared regeneration and microwave regeneration. The back flushing regeneration utilizes compressed air to back flush the DPF, and the energy consumption is relatively low. The passive regeneration has the advantages of no need of energy consumption, but has the disadvantages of poor controllability, easy burning-through of the carrier and no guarantee of safety; wherein the requirement of heavy load regeneration on the working condition is higher; the regeneration of the catalyst is required to be carried out under the condition of low smoke intensity emission, and the catalyst is easy to be poisoned, so that the catalytic purification effect is influenced; the fuel oil additive requires low-sulfur diesel oil, the sulfur content of the domestic diesel oil is generally higher at present, and the additive can generate secondary pollution when being combusted.
