Description

Technical Field

[0001] This utility model relates to the field of low-carbon gel material production technology, specifically a spray dryer for low-carbon gel material production. Background Technology

[0002] Low-carbon cementitious materials are a new type of environmentally friendly building material designed to replace traditional silicate cement in order to reduce energy consumption and carbon emissions. With increasing environmental awareness and growing concern about energy consumption, low-carbon cementitious materials require efficient drying equipment during production to reduce energy consumption and carbon emissions. The working principle of a spray dryer is to rapidly atomize the liquid material into fine droplets through centrifugal force or pressure, thereby obtaining a large specific surface area, and then transforming it into dry powder upon contact with hot air.

[0003] Traditional spray dryers suffer from poor thermal circulation, high energy consumption, and low drying efficiency when processing low-carbon gel materials. In particular, the hot exhaust gas cannot be effectively recycled, resulting in high energy consumption.

[0004] Therefore, a new type of spray dryer is needed to improve drying efficiency, reduce energy consumption, and reduce carbon emissions. Utility Model Content

[0005] The purpose of this invention is to provide a spray dryer for the production of low-carbon gel materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spray dryer for the production of low-carbon gel materials, comprising a drying chamber and a hot air supply cylinder. The drying chamber is internally enclosed by a drying cylinder, and a ventilation channel is provided at the connection between the outer wall of the drying cylinder and the inner wall of the drying chamber. Heat-conducting plates are arranged inside the ventilation channel. The inner wall of the drying cylinder has a downward conical structure, and turbine blades are arranged around the inside of the drying cylinder. A breathable hood is provided at the bottom of the drying cylinder and the connection between the ventilation channel and the bottom of the breathable hood is connected to a particle collection chamber. An air outlet groove is opened at the top of the ventilation channel, and exhaust gas filter sleeves are fitted around the outer sides of multiple sets of air outlet grooves. The hot air supply cylinder is arranged in a ring shape, and air outlet holes are arranged around the bottom of the hot air supply cylinder. An embedded groove is opened in the middle of the hot air supply cylinder, and a spray atomizer is installed on the inner side of the embedded groove. A gas supply pipe is installed on the outer side of the top of the hot air supply cylinder, and the spray nozzle of the spray atomizer is...

[0007] Furthermore, the hot gas supply cylinder is connected by an embedded groove and a jet atomizer.

[0008] Furthermore, the drying chamber and the drying cylinder are connected in a wrapping manner, and the outer walls of the drying chamber are provided with support legs on both sides.

[0009] Furthermore, the drying cylinder is interconnected with the ventilation hood and the ventilation channel.

[0010] Furthermore, the hot gas supply cylinder is interconnected with the drying cylinder through an outlet trough.

[0011] Furthermore, the turbine blades are arranged in a spiral shape and are attached to the inner wall of the drying cylinder.

[0012] Furthermore, the exhaust gas filter sleeve and the multiple sets of exhaust slots form an encapsulated connection.

[0013] This utility model provides a spray dryer for the production of low-carbon gel materials, which has the following features:

[0014] Beneficial effects:

[0015] 1. This utility model uses a drying cylinder as the drying space and provides spiral turbine blades on the inner wall of the drying cylinder, which can guide the hot air transmitted from the top, making the hot air transmission smoother. It can also atomize the gel material sprayed at the center of the top into tiny particles, increasing the contact area with the hot air and improving the drying efficiency.

[0016] When hot air enters, it is guided by a hot air supply cylinder and discharged from the embedded groove on the bottom side. This ensures the uniformity of the hot air during heating and also shortens the contact path between the hot air and the atomized gel material, reducing energy consumption during drying.

[0017] 2. In this utility model, a ventilation channel is provided at the connection gap between the drying chamber and the drying cylinder. The ventilation channel is connected to the bottom ventilated cover mesh, so that the hot air transmitted from the top of the drying cylinder from top to bottom passes through the ventilated cover mesh and enters the ventilation channel, and then is discharged through the air outlet groove opened at the top.

[0018] The exhaust gas enters the ventilation channel for circulation, allowing the heat carried by the exhaust gas to be transferred inwards and absorbed by the heat-conducting plates on the inside. This process recovers and utilizes the heat carried by the exhaust gas, reducing the drying energy consumption rate.

[0019] 3. In this utility model, an exhaust gas filter sleeve is also fitted on the outside of the exhaust slot, which can adsorb and filter the exhaust gas, reduce exhaust gas emissions and air pollution, and achieve the goal of low-carbon and environmentally friendly production.

[0020] The bottom of the breathable hood is connected to the particle collection chamber, allowing the dried particles to fall into the particle collection chamber for collection, resulting in high equipment reliability and stability. Attached Figure Description
