Description

Technical Field

[0001] This utility model relates to the field of circulating granulation systems, specifically an inert gas closed-loop circulating granulation system. Background Technology

[0002] With rapid economic development, production in all sectors is constantly expanding, and production technologies are continuously being updated. Granulation is an essential step in the production of granular products. Traditional granulation methods include high-tower granulation, rotary drum granulation, pressure spray granulation, and centrifugal spray granulation. High-tower granulation and rotary drum granulation are generally used for large particle granulation; pressure spray granulation and centrifugal spray granulation are generally used for powder products. Different granulation methods are selected based on different particle sizes. The granulation process generally uses cold air to contact and cool the material to achieve the purpose of granulation.

[0003] Because air contains oxygen, traditional granulation processes are not suitable for some special materials (products with explosive risks). Due to the special properties of some materials, the oxygen content needs to be controlled during the granulation process for safe production. Therefore, it is necessary to use inert gases to granulate under air-isolated conditions. Thus, we propose an inert gas closed-loop circulation granulation system. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an inert gas closed-loop circulation granulation system to solve the technical problem that traditional granulation processes are not applicable to some special materials (products with explosive risks) because the air contains oxygen.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an inert gas closed-loop circulation granulation system, including: a granulation tower, a product collector, a power machine, an oxygen concentration sensor, and a heat exchanger;

[0006] A pipe connects the granulation tower and the product collector, a pipe connects the product collector and the power machinery, a pipe connects the power machinery and the heat exchanger, and a pipe connects the heat exchanger and the granulation tower.

[0007] Preferably, an oxygen concentration sensor is installed in the outlet pipe of the power machinery.

[0008] Preferably, when the oxygen concentration detected by the oxygen concentration sensor is higher than the set value, the gas replenishment valve is opened to replenish inert gas to the system.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model can provide a safe, stable and reliable production system for products with explosive risks, and solves the technical problem that traditional granulation processes are not applicable to some special materials (products with explosive risks) because the air contains oxygen.

[0011] 2. This utility model can effectively monitor and control the oxygen concentration of the system within a specified range by setting an oxygen concentration sensor, thereby eliminating the risk of explosion of special materials. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the system of this utility model. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] Example 1: An inert gas closed-loop granulation system, see [link to example]. Figure 1 The system includes: a granulation tower, a product collector, power machinery, an oxygen concentration sensor, and a heat exchanger. Pipes connect the granulation tower and the product collector, the product collector and the power machinery, the power machinery and the heat exchanger, and the heat exchanger and the granulation tower. Liquid product enters the granulation tower from the top, is granulated, and then cooled by contact with inert gas. The cooled product exits from the bottom of the granulation tower, while the cooling gas flows out from the top and enters the product collector, where some of the product carried by the cooling gas is collected. The exhaust gas exits from the product collector, is pressurized by the power machinery, cooled by the heat exchanger, and then re-enters the granulation tower for the next cycle. This cycle, involving circulation with inert gas, reduces the oxygen concentration, thereby eliminating the risk of explosion. This system provides a safe, stable, and reliable production system for products with explosive risks, solving the technical problem that traditional granulation processes are not suitable for some special materials (products with explosive risks) due to the presence of oxygen in the air.

[0015] For details, see Figure 1 Installing an oxygen concentration sensor in the outlet pipe of the power machinery can effectively monitor and control the oxygen concentration of the system within the specified range, thereby eliminating the risk of explosion of special materials.

[0016] Further, see Figure 1 When the oxygen concentration sensor detects that the oxygen concentration of the system is higher than the set value, the gas replenishment valve is opened to replenish inert gas to the system.

[0017] In an inert gas closed-loop granulation system, the liquid product enters the granulation tower from the top. After granulation, it is cooled by contact with inert gas. A portion of the cooled product exits from the bottom of the tower, while the gas flows out from the top into a product collector. The remaining product is collected here. The exhaust gas exits the product collector, is pressurized by a power machine, cooled by a heat exchanger, and then re-enters the granulation process for the next cycle. This inert gas circulation reduces the oxygen concentration, thereby minimizing the risk of explosion. This system provides safe, stable, and reliable production for products with explosive risks. The presence of an oxygen concentration sensor effectively monitors and controls the system's oxygen concentration within a specified range, thus eliminating the risk of explosions of certain materials.
