Embodiment 1

[0038] Such as figure 1 The shown embodiment of the present invention provides a smoke treatment system, the system includes:

[0039] Primary processing device 101, secondary processing device 102, security processing device 103;

[0040] The primary treatment device 101 includes: a smoke inlet, a treatment chamber and a smoke exhaust outlet, and the treatment chamber is provided with a first cooling water coil, a water curtain nozzle and a second cooling water pan in sequence from the smoke inlet to the smoke outlet pipe; cooling water is injected from the water inlet of the first cooling water coil and the second cooling water coil, and flows out from the water outlet, and the water curtain nozzle is used to spray lime water;

[0041] The secondary treatment device 102 includes: a smoke inlet, a treatment chamber and a smoke exhaust port, the smoke inlet is connected with the smoke exhaust port of the primary treatment device; the treatment chamber is sequentially provided...

Embodiment 2

[0091] Such as Figure 7 The illustrated embodiment of the present invention also provides a soot treatment process, comprising the following steps:

[0092] Step 701: Use the first cooling water coil, the water curtain nozzle, and the second cooling water coil in the treatment chamber of the primary treatment device to perform the first waste heat recovery and the second waste heat recovery for the smoke and exhaust gas from the smoke inlet of the primary treatment device respectively. One washing and second waste heat recovery;

Abstract

The invention discloses a smoke processing system and a method thereof. The system comprises a primary processing apparatus, a secondary processing apparatus and a security processing apparatus; three times processing can be carried out on smoke and exhaust gas by the primary processing apparatus, the secondary processing apparatus and the security processing apparatus in order, so that smoke discharge capacity is reduced at maximum degree, multi-time washing on smoke and exhaust gas is carried out by employing a water screen nozzle and a water mist spray nozzle apparatus, equipment loss due to obstruction of smoke particles is reduced; twice waste-heat recovery on high-temperature smoke and exhaust gas can be carried out by employing the primary processing apparatus, energy is saved; an active carbon adsorption layer is arranged on the security processing apparatus for absorbing harmful substance such as dioxin which is difficultly removed by high temperature and a chemical reaction mode, and harm on environment by the harmful substance such as dioxin is reduced.

Description

technical field [0001] The invention relates to the field of soot treatment, in particular to a system and method for soot treatment. Background technique [0002] The soot and waste gas produced by waste-to-energy plants after burning waste can only be discharged into the atmosphere after being treated up to standard. At present, the treatment process of soot and exhaust gas is usually: filter through high-temperature bag filter, wash through scrubber to remove harmful substances in soot and exhaust gas, and the sewage from scrubbing exhaust gas can be provided to the scrubber for recycling after treatment. [0003] However, in the methods for processing soot in the prior art, there is a strong dependence on the soot collection equipment and scrubber equipment, and the equipment will always be lost due to the blockage of soot, and the downtime and cost caused by equipment maintenance will affect the efficiency of the soot treatment system. And there is also a lack of equip...
