Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, this fuel cracking furnace tail gas treatment system includes a carbon dust filter system connected to the cracking furnace, and the carbon dust filter system includes a connecting pipe 1 communicating with the cracking furnace, and the connecting pipe 1 is a square pipe , the other end of which is connected to the hot air water buffer chamber 3, and two or more layers of multi-layer water curtain sprays are arranged in the connecting pipeline, and two layers of water curtain sprays are arranged in the buffer chamber 3, connected from a square The hot gas entering the pipeline weakens the destructive thermal impact force caused by the flue gas (water) driving the carbon particles in the flue gas under the action of multi-layer water curtain spraying and buffer chamber; at the same time, a carbon residue filter 4 is installed at the low...

Abstract

The present invention discloses a fuel cracking furnace containing a boiler, horizontal waste plastics and a waste tyre cracking furnace tail gas treatment system, wherein, fuel comprises solid fuel and gas fuel or liquid fuel. The tail gas treatment system comprises a carbon dust particle filtration system connected with the fuel cracking furnace, a gas-solid separation system connected with the carbon dust particle filtration system, a flue gas emission system connected with the gas-solid separation system, and a circulating water cooling system. Compared with the prior art, the tail gas treatment system is environmental-friendly and economical; the system has long service life and convenient and fast assembly and disassembly; and the system can reduce or eliminate carbon dust particles in tail gas, and the emission temperature is approximately identical with the atmospheric temperature.

Description

technical field [0001] The invention relates to an environmental protection treatment system for tail gas emission of combustion equipment, in particular to a horizontal fuel cracking furnace tail gas treatment system. This cracking furnace includes a boiler and a horizontal waste plastic and waste tire cracking furnace. The fuel includes solid fuel and gaseous or liquid fuel. Background technique [0002] At present, there are a variety of exhaust and treatment systems for horizontal fuel cracking furnaces, but these systems will suffer severe damage to pipes and equipment in a short period of time during use, and the water pump will be scrapped due to high water temperature. Because the problem of destructive impact on pipelines and equipment caused by carbon dust particles driven by hot air flow is not considered, at the same time, there are relatively large black smoke and high-temperature emissions in the process of exhaust exhaust. For example, the Chinese patent appl...
