两风道四风闸环保节能一次码烧轮窑

Double air duct four-air brake environment-friendly and energy-saving ring kiln formed in semi-stiff extrusion process

Abstract

The utility model relates to a double air duct four-air brake environment-friendly and energy-saving ring kiln formed in a semi-stiff extrusion process, which is characterized in that the middle partof a kiln body (1) is provided with two main air ducts, one air duct is a main air duct (17) for discharging smoke and damp in the upper layer, and a damp discharge air brake (9) and a smoke dischargeair brake (8) are arranged in the main air duct (17); the other air duct is a main air duct (18) for pumping after heat in the lower layer, an air brake (5) for pumping after heat is arranged on theupper part of the main air duct (18), and an air brake (6) for sending the after heat is arranged on the lower part of the main air duct (18). By the two air ducts and the four air brakes, the ring kiln optimizes the ventilation system, realizes heat pumping in the upper part, heat sending in the lower part, damp discharge in the upper part and smoke discharge in the lower part of a kiln room, utilizes a desulphurization and dust removal system to achieve environmental protection, is a kiln type with small investment, low energy consumption and high output, and can not collapse.
一种两风道四风闸环保节能一次码烧轮窑其特征是:窑体(1)中间部分设有两条主风道,一条为上层的排烟排潮主风道(17),风道内安设有排潮风闸(9)与排烟风闸(8);另一条为下层的抽送余热主风道(18),风道上部安设有抽余热风闸(5),风道下部安设有送余热风闸(6)。通过两条风道,四种风闸优化了轮窑通风系统,实现了窑室上抽热,下送热,上排潮,下排烟,利用脱硫除尘系统实现了环保,是一种投资少,能耗低,产量高,不倒窑的窑型。
