Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for pharmaceutical preparation. Background Technology
[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. In particular, waste gases emitted by chemical plants, steel mills, pharmaceutical factories, and oil refineries have strong odors, seriously polluting the environment and affecting human health. The modern pharmaceutical industry inevitably uses large quantities of chemical and biological agents in its production processes, thus generating significant amounts of waste gas.
[0003] The pharmaceutical industry generates a large amount of waste gas during the production process. This waste gas contains a variety of harmful substances, such as volatile organic compounds (VOCs) and particulate matter, which pose serious threats to the environment and human health.
[0004] Currently, waste gas treatment typically employs a combination of physical and chemical methods. On one hand, particulate matter is filtered using filtration components; on the other hand, a catalyst is used to catalyze the oxidation of the waste gas. However, pharmaceutical waste gas exhibits unstable temperatures after filtration, sometimes reaching high levels, making it difficult to match the optimal reaction temperature of the catalyst and resulting in low waste gas treatment efficiency. Utility Model Content
[0005] Based on the above situation, the main purpose of this utility model is to provide a pharmaceutical material processing waste gas treatment device to solve the problem that the temperature of pharmaceutical waste gas is unstable after filtration, and the temperature is too high, making it difficult to match the optimal reaction temperature of the catalyst, resulting in low waste gas treatment efficiency.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The filtration assembly, cooling assembly, and catalytic assembly are connected in series;
[0009] The cooling assembly includes a cooling cylinder and a cold water pipe, wherein the cold water pipe is a spiral-shaped pipe.
[0010] The catalytic assembly includes a catalytic tower and a catalyst bed, the catalyst bed being fixed inside the catalytic tower and having a honeycomb structure.
[0011] Preferably, a second connecting pipe is provided between the cooling cylinder and the catalytic tower;
[0012] An electric valve and a temperature sensor are installed in the middle of the second connecting pipe.
[0013] Preferably, the electric valve is located closer to the cooling cylinder than the temperature sensor.
[0014] Preferably, it also includes an emission assembly, which includes a fan and a flue, a third connecting pipe connecting the flue and the catalytic tower, and the fan being disposed in the middle of the third connecting pipe.
[0015] Preferably, the inside of the flue is fixed with an activated carbon layer.
[0016] Preferably, both the inlet and outlet ends of the cold water pipe extend outside the cooling cylinder.
[0017] The beneficial effects of this utility model are as follows: the catalyst bed is honeycomb-shaped, which allows the cooled flue gas to fully undergo catalytic oxidation reaction after entering the catalytic component, converting harmful gases into harmless gases. In this application, a spiral cooling water pipe and a honeycomb-shaped catalyst bed are used in combination, so that the exhaust gas can be adapted to the catalyst reaction temperature, allowing the exhaust gas to be stably catalytically oxidized, meeting the exhaust gas emission standards, and improving the exhaust gas treatment efficiency.

[0029] Reference Figure 1-3 This utility model provides a pharmaceutical manufacturing waste gas treatment device, including a filter assembly 1, a cooling assembly 2, a catalytic assembly 3, and an emission assembly 4. The filter assembly 1, cooling assembly 2, and catalytic assembly 3 are interconnected. The filter assembly 1 removes particles from the waste gas, the cooling assembly 2 lowers the temperature of the waste gas, and the catalytic assembly 3 can be equipped with a catalytic oxidant to convert the waste gas into harmless substances. The gas converted into harmless substances can be discharged through the emission assembly 4.
[0030] One end of the filter assembly 1 is connected to the pharmaceutical equipment through the air inlet pipe 11 to collect exhaust gas. The internal structure of the filter assembly 1 can be an electrostatic precipitator or a multi-layer filter cotton screen structure. The above structures are all existing technologies and will not be described in detail in this application. The filter assembly 1 is mainly used to remove particles in the exhaust gas so that the exhaust gas can enter the catalytic assembly 3 for better reaction.
[0031] The cooling assembly 2 includes a cooling cylinder 21 and a cold water pipe 22. The cooling cylinder 21 is fixed to the ground by a straight rod and is vertically arranged. The cooling cylinder 21 and the filter assembly 1 are connected by a first connecting pipe 12. The first connecting pipe 12 can discharge the filtered flue gas into the cooling assembly 2. The cold water pipe 22 is a spiral pipe and is fixed in the cooling cylinder 21. The inlet and outlet of the cold water pipe 22 extend to the outside of the cooling cylinder 21. The inlet and outlet of the cold water pipe 22 can be connected to an external circulating refrigeration system, so that the inside of the cooling cylinder 21 can be kept at a low temperature to maintain the cooling effect on the exhaust gas.
[0032] A second connecting pipe 211 is fixed to the upper end of the cooling cylinder 21, and the second connecting pipe 211 is connected to the catalytic assembly 3. The catalytic assembly 3 includes a catalytic tower 31 and a catalyst bed 32. The catalytic tower 31 is connected to the second connecting pipe 211, and the catalyst bed 32 is fixed inside the catalytic tower 31. The catalyst used in the catalytic assembly 3 can be a metal oxide, which is less expensive than precious metal catalysts. The catalyst bed 32 is honeycomb-shaped, which allows the cooled flue gas to fully undergo catalytic oxidation after entering the catalytic assembly 3, converting harmful gases into harmless gases. In this application, a spiral cooling pipe and a honeycomb-shaped catalyst bed 32 are used in combination, so that the exhaust gas can be adapted to the catalyst reaction temperature, allowing the exhaust gas to be stably catalytically oxidized, meeting the exhaust gas emission standards, and improving the exhaust gas treatment efficiency.
[0033] In one embodiment, an electric valve 212 and a temperature sensor 213 are provided in the middle of the second connecting pipe 211. The temperature sensor 213 is connected to the electric valve 212 and is located closer to the cooling cylinder 21 than the electric valve 212. The flue gas discharged through the cooling cylinder 21 can remain in the cooling cylinder 21 and the second connecting pipe 211 under the control of the electric valve 212. The temperature sensor 213 detects that the temperature of the exhaust gas in the second connecting pipe 211 is within a suitable range. The temperature sensor 213 can send a command to the electric valve 212 or manually control the electric valve 212 to open it, so that the flue gas with a suitable temperature enters the catalytic tower 31.
[0034] The emission assembly 4 includes a fan 41 and a flue 42. A third connecting pipe 33 is fixed below the catalytic tower 31, connecting the third connecting pipe 33 and the flue 42. The fan 41 is located in the middle of the third connecting pipe 33. The flue 42 is vertically arranged, allowing the flue gas emitted from the catalytic tower 31 to be discharged through the flue 42. The inside of the flue 42 has an activated carbon layer 421, which further removes residual harmful substances. It should be noted that the top of the flue 42 can be equipped with detection devices such as thermocouples or infrared spectrometers as needed; this will not be elaborated upon in this application.
[0035] The implementation principle of this utility model is as follows: the catalyst bed 32 is honeycomb-shaped, which allows the cooled flue gas to fully undergo catalytic oxidation reaction after entering the catalytic component 3, converting harmful gases into harmless gases. In this application, the spiral cooling water pipe 22 and the honeycomb-shaped catalyst bed 32 are used in combination, so that the exhaust gas can be adapted to the catalyst reaction temperature, allowing the exhaust gas to be stably catalytically oxidized, achieving the exhaust gas emission standards and improving the exhaust gas treatment efficiency.
