Description

A kind of annular air curtain suitable for medicament compartment material filtering centrifuge pollutant catabolic gene The exhaust system combined
Technical field
This patent proposes a kind of annular air curtain suitable for medicament compartment material filtering centrifuge pollutant catabolic gene and mutually ties The exhaust system of conjunction belongs to the field of industrial ventilation, pollutant catabolic gene.
Background technique
As people increasingly pay close attention to natural environment, working environment, prevent industrial pollutants pollution room air from most having The method of effect is: generating place in pollutant and is directly trapped, by purified treatment, drains into outdoor, local ventilation is in industry In be also used widely.
Layout in each post of the technique of pharmaceutical factory will meet design and GMP requirement, be divided into the design of main production district Clear production area and general production district, clear production area are designed according to the requirement of cleanliness, and general production district has hygienic requirements, but No clean rank requirement, such as bulk pharmaceutical chemicals synthesis, antibiotic fermentation and refinement, Chinese medicine liquid extract and liquid extract dissipate (powder) agent, pre- The workshops such as mixture, sterilizing, packaging.The general technology process in pharmaceutical factory: raw material, purification, processing, extraction, concentration, medicinal extract, drying, Crushing, tabletting, coating, finished product.Various particulate matters, steam and gas pollutant can be distributed during drying and crushing, if being not added To control and handle, indoor air environment can be made to be contaminated, endanger workers ' health, influence the normal operation of production process, It can also cause damages simultaneously to the environment of the Nature.
After the collection processing for carrying out pollutant frequently with local ventilation in the general production district of pharmaceutical factory at present, collection Middle discharge, but common exhaust hood will appear that inspiratory flow velocity attenuation is very fast, while the disturbance vulnerable to crossflow, traditional row The arresting efficiency of fan housing is lower, and pollutant is easily diffused into surrounding working environment, causes to cause environment to the health problem of worker Pollution the problems such as.
Chinese invention patent " annular umbrella-like gas-proof curtain exhaust hood " (application number: CN95114855, publication date: 1995.12.13) Realize with motor be axially that the coniform air draught part in center region and the annular umbrella-like air curtain around center air draught region are dried Part had not only effectively prevent the diffusion of pernicious gas, but also enhanced local suction effect.But this design has some shortcomings, from annular The flow direction of jet stream and circular cone exhaust hood suction airflow that umbrella air curtain sprays around is inconsistent, has violated air motion side To the consistency principle, and the air current composition disorder below exhaust hood, the possibility for having pollutant to reveal, while whole system are in the presence of dynamic The waste of power, it is therefore necessary to this design be improved, the arresting efficiency of pollutant is more effectively improved, reduce energy consumption, improve medicine Factory's environmental amenity.
Summary of the invention
This patent purpose is provided in medicament compartment material filtering centrifuge pollutant catabolic gene and combines annular gas-proof curtain exhaust hood Local ventilation system.On the basis of original exhaust system, annular air curtain is installed in material filtering centrifuge middle and upper part, in material When filtering centrifuge is opened, annular air curtain exhaust system is opened simultaneously.
This patent described problem is mainly achieved through the following technical solutions:
The present invention discloses a kind of air draft system that the annular air curtain suitable for medicament compartment centrifuge pollutant catabolic gene combines System, the system are mainly made of annular air curtain stream portion, centrifuge, air section and air exhaust part.The air section by Axial flow blower, hose coupling, threeway, air supply tube branch pipe composition.
Centrifuge, annular air curtain and exhaust hood are concentric, and annular air curtain is mounted on centrifuge, air section by fresh air send to Annular air curtain, air curtain jet stream and the equidirectional effect of exhaust hood inspiratory airflow form Push-pull Flow, and it is upward that fresh air passes through annular air curtain Pollutant is sent into exhaust hood mouth by jet stream, and the gas stream of pollution volume of rising inhales surrounding flow and forms interflow, and exhaust hood inhales pollutant Enter in cover, while blocking the polluted gas in centrifuge or particulate matter leaks to factory, efficiently controls the diffusion of pollutant, The processing discharge of exhaust hood centralized collection.
This system can effectively separate lateral gas and collect pollutant effects to exhaust hood, prevent the diffusion of pollutant Influence the health of people;Arresting efficiency good to the control effect of pollution source gas, that exhaust hood is improved using lesser air quantity, is reduced Energy consumption;Structure is simple, and installation is easy to operate, and operating cost is low.Use scope of the present invention is suitable for industrial premises workshop pernicious gas Local exhaust occasion.
Detailed description of the invention
