specific Embodiment approach 1

[0023] Specific implementation mode 1: The light-weight residential flue of this embodiment is composed of a flue outer shell 1, an intermediate layer 2 and a granular porous adsorption material 3;

[0024] The flue casing 1 is long cylindrical and has a rectangular cross-section; the middle layer 2 is arranged on the inner wall of the flue casing 1, and the granular porous adsorption material 3 is attached to the inner wall of the middle layer 2;

[0025] The middle layer 2 is foamed cement; the density of the foamed cement is 100-120kg / m 3 ;

[0026] The loose bulk density of the granular porous adsorption material 3 is 70-110kg / m 3 , with a particle size of 1 to 3 cm; the granular porous adsorption material 3 is modified foamed glass particles;

[0027] The flue outer shell 1 is poured from lightweight aggregate concrete.

[0028] This embodiment has the following beneficial effects:

[0029] 1. The middle layer 2 in the outer casing 1 of the flue of the present inventi...

specific Embodiment approach 2

[0033] Embodiment 2: This embodiment differs from Embodiment 1 in that: the thickness of the flue casing 1 is 1-3 cm. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0034] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the preparation method of the modified expanded glass particles is carried out according to the following steps:

[0035] ①. Glass powder with a particle size of 30-40 μm, calcium carbonate powder with a particle size of 10-20 μm and Al with a particle size of 33-47 μm 2 o 3 Mix the powder evenly to obtain a mixed powder; spread the mixed powder in a metal tray with a thickness of 0.5cm, then place the metal tray at 650-700°C for 3-5 minutes, and cool it naturally to At room temperature, a glass frit is obtained; the glass frit is crushed to a particle size of 30-40 μm to obtain a composite foaming agent;

[0036] The glass powder, calcium carbonate powder and Al 2 o 3 The mass ratio of powder is (0.8~1):1:0.02;

[0037] In the preparation of the existing foam glass with calcium carbonate as foaming agent, it is generally necessary to add low melting point substa...

Abstract

A light-weight residential chimney relates to a residential chimney. The purpose is to solve the problem that the flue is easy to be damaged in the existing residence. The light-weight residential flue is composed of a flue shell, an intermediate layer and granular porous adsorption materials. The preparation method: pouring light aggregate concrete to obtain the outer shell of the flue; pouring foamed glass particles and foaming slurry into the outer shell of the flue to complete the preparation of the middle layer and the granular porous adsorption material. The light-weight residential flue of the present invention can offset the impact force of falling objects layer by layer from the inside and outside, avoid or weaken the damage to the outer shell of the flue, and the middle layer and granular porous adsorption materials can adsorb tiny particles, acid gases, etc. Compared with direct discharge, it reduces the pollution to the atmosphere, and can also play the function of sound absorption and noise reduction, saving the use of sound insulation coating materials on the outer wall of the flue. The invention is suitable for residential smoke exhaust.

Description

technical field [0001] The invention relates to a house flue. Background technique [0002] The flue in a high-rise or multi-storey residence is mainly used to discharge the smoke and heat generated in the kitchen to the outside. The flue is mostly thin-walled and lightweight structure, such as the flue made of glass magnesium board made of glass fiber mesh cloth reinforced magnesite cementitious material, and is made of light aggregate to reduce the cost and reduce the weight of the flue. There are also flues made of Portland cement as the cementitious material, but cement cementitious materials and magnesite cementitious materials are inorganic cementitious materials, which are prone to brittle fracture. When decoration is carried out in the building after the flue is installed, the falling objects in the flue are the main reason for the brittle damage of the flue. After the flue is hit by the falling object, cracks will occur in light cases, and holes will be formed in s...
