a cooling tower

Abstract

The invention relates to a quenching tower, comprising an outer steel sleeve and an inner graphite sleeve, the upper and lower ends of the outer steel sleeve are respectively covered with an upper spray cover plate and a lower cover plate; The shaft is installed in the outer steel sleeve, and forms a cooling water cavity with the inner wall of the outer steel sleeve, which can accommodate the circulation of cooling water. The inner wall is a spray inner cavity for gas spraying. The spray cover plate is connected, and its lower end is directly connected with the lower cover plate; the upper part of the outer steel sleeve has a cooling water outlet and a drain port, the cooling water outlet and the drain port are staggered, and the drain port is located at the cooling above the water outlet; the lower part of the outer steel sleeve has a cooling water inlet and a clean discharge port, the cooling water inlet and the clean discharge port are staggered, and the clean discharge port is located below the cooling water inlet. The advantages of the present invention are: adopting the quenching tower, the structure is simple, the manufacture is convenient, and the tail gas produced after high-temperature incineration can be effectively quenched, so as to solve the problems of environmental pollution, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a quenching tower, in particular to a quenching tower for quenching tail gas generated after high-temperature incineration. Background technique [0002] After medical waste is incinerated at high temperature, not only the waste is harmlessly reduced, but also toxic and harmful substances and dioxins are effectively treated. [0003] Dioxins can still be synthesized at around 300 degrees, so rapid cooling is required, and dioxins in the environment are difficult to degrade and eliminate naturally. It includes 210 compounds, and its toxicity is very high, 900 times that of arsenic. Known as the "poison of the century", one ten thousandth or even one hundred millionth of a gram of dioxin will bring serious harm to health. [0004] Dioxins often exist in the atmosphere, soil and water in the form of tiny particles. The main sources of pollution are chemical and metallurgical industries, waste incineration, papermaking, and pestic...
