Embodiment 1

[0033] As shown in Figure 1 and 4.

[0034]A multi-tower ozone sterilization system, including an ozone generator (the same as the prior art, can be purchased directly from the market), an air supply device (composed of a fan A' and a fan B'), a first air-powder mixing The main tower 28 and the second air-powder mixing main tower 48, the ozone generator is connected with the air outlet ducts of the air supply fan A' and the fan B' through the pipeline, and the air inlet and outlet of the fan A' and the fan B' pass through the corresponding The pipeline is connected with the corresponding inlet and return ducts on the first gas-powder mixing main tower 28 (A tower) and the second gas-powder mixing main tower 48 (B tower). The powder mixing main towers 48 are directly or indirectly connected with a powder feeding pipeline and a powder returning pipeline for sending powder from one main tower to another main tower. Catalytic converter, 8 and gas cooler are installed on the outpu...

Embodiment 2

[0038] As shown in Figures 1, 3, and 5.

[0039] The difference between the present embodiment and embodiment one is only that the air supply device only uses a fan 1 (should adopt a high-pressure fan), and the layout of the fan 1, the odor generator 11 and the control valve is as follows: Figure 5 shown. By controlling the opening and closing of valves 3, 4, 9, and 10, one fan can be used to change the wind direction between the two main towers, so that the powder in one tower can be sent to the other tower and can work alternately. , compared with Embodiment 1, a fan can be omitted, but the control part is slightly more complicated.

Embodiment 3

[0041] As shown in Figure 2 and 3.

[0042] The difference between this embodiment and Embodiment 1 is that an intermediate mixing tower N is connected in series between the two main towers A and B (multiple series can also be used as required) to extend the powder transportation path. , the intermediate mixing tower 63 has only powder inlet and outlet pipes, as shown in Figure 2. Specifically, the bottom of the intermediate mixing tower 63 is provided with an air powder distributor 54, an air powder input pipe 66 and an air powder output pipe 58 are installed on its upper end, and an air guide pipe 62 is installed on the tower wall to distribute the air powder. The device 54 is connected to each other with the gas powder output pipe 58 stretching out outside the tower by the suction pipe 56, and the gas powder input pipe 66 is mixed with the gas powder output pipe 58 on the adjacent intermediate mixing tower or the gas powder on the first gas powder mixing main tower. The po...

Abstract

The invention disclose a multi-tower powder ozone sterilization system which is characterized in that an air supply device, an ozone generator, a first air-powder mixing main tower and a second air-powder mixing main tower are included. An air suction pipe and an air return pipe which can generate positive pressure and negative pressure in an alternative way in the two towers are connected between the first air-powder mixing main tower and the second air-powder mixing main tower; the air supply device is connected between an air supply pipe and the air return pipe in series; a powder supply pipeline and a powder return pipeline which send powders from one tower to the other tower are also connected between the first air-powder mixing main tower and the second air-powder mixing main tower; and the powder supply pipeline of one main tower is communicated with the powder return pipeline of the other main tower; air-powder distributors are arranged on the lower parts of the first air-powder mixing main tower and the second air-powder mixing main tower; the tops of the towers are both provided with air-powder filters that cause the air suction pipe and the air return pipe of each main tower to be indirectly communicated with a tower cavity which is filled with the powders to ensure that the powders are not contained in the air suction pipe or the air return pipe. The system has the advantages of simple structure, favorable sterilization effect, energy conservation, environmental protection and wide application.

Description

technical field [0001] The invention relates to a powdery material sterilization equipment, especially a kind of equipment that uses ozone to sterilize powdery materials such as medicine powder, milk powder, edible powder, chemical industry or pharmaceutical raw material powder, specifically a kind of equipment that uses air force Conveying principle A multi-tower ozone sterilization system that realizes disinfection and sterilization during the process of moving powder from one tower to another. Background technique [0002] At present, traditional sterilization methods for powder and powdery materials (such as traditional Chinese medicine, Chinese patent medicine, western medicine raw material powder, edible powder, milk powder, etc.) at home and abroad include dry heat, damp heat, Co60, ethylene oxide and other methods. However, due to the nature of the material and high temperature, the loss of its components is large, and the operating costs of Co60 and ethylene oxide a...
