Quenching smoke-removing device with vertical low-resistance cooling system

Abstract

The invention discloses a quenching smoke-removing device with a vertical low-resistance cooling system. The quenching smoke-removing device is characterized by comprising a quenching tower, a collecting cover, a quenching vehicle and a shell tube, wherein the collecting cover is located above the quenching tower; the quenching vehicle is located in the quenching tower; the shell tube is communicated with the collecting cover; the vertical low-resistance cooling system is vertically fixed in the shell tube; a dust collector is communicated with a side wall of the shell tube; a water outlet of the shell tube is communicated with a wastewater pool; the vertical low-resistance cooling system comprises a cooling pipe; an inlet end of the cooling pipe is communicated with one end of a cooling liquid inlet pipe; an outlet end of the cooling pipe is communicated with one end of a cooling liquid outlet pipe; the other end of the cooling liquid inlet pipe and the other end of the cooling liquid outlet pipe are respectively communicated with a cooling liquid circulating cooling device. According to the invention, the vertical low-resistance cooling system is vertically arranged in the shell tube, so that the condensate water downward vertically flows out of the wastewater pool under the effect of gravity and the waste of water resource and the environmental pollution are greatly reduced.

Description

Technical field [0001] The invention relates, in particular to a flue gas treatment device, and in particular to a coke quenching and smoke removal device with a vertical low-resistance cooling system. Background technique [0002] Water quenching refers to a method in which the spray device in the quenching tower sprays the quenching water on the hot red coke placed on the quenching car at the bottom of the quenching tower to cool the hot red coke into normal temperature coke. When quenching the coke with water, the quenching water will produce a lot of high temperature flue gas when it encounters the hot red coke. The flue gas contains a lot of water vapor and harmful substances. Usually the flue gas will be directly discharged into the atmosphere from the top outlet of the quenching tower , This has caused serious pollution to the environment, and the exhausted flue gas contains a lot of water vapor, and also caused a waste of water resources. Summary of the invention [0003]...

AI Technical Summary

Problems solved by technology

During coke quenching with water, when the coke quenching water encounters hot red coke, a large amount of high-temperature flue gas will be generated. The flue gas contains a large amount of water vapor and harmful substances. Usually, the flue gas will be directly discharged into the atmosphere from the top outlet of the coke quenching tower. , which has caused serious pollution to the environment, and the exhausted flue gas contains a large amount of water vapor, which has also caused a waste of water resources
