Mute type self-circulation type clean operating room
The utility model relates to air cleaning facility technical field, particularly relates to a kind of mute type self-circulation type clean operating room.
Clean operating room is the control adopting air purity technique to take degree different to microbial contamination, reaches air purity in control space environment and is suitable for the requirement of all kinds of operation, and provide suitable epidemic disaster, create the operative space environment that a cleaning is comfortable.
The air (first the air entering operating room must purify through high efficiency particulate air filter) of existing clean operating room technology major requirement high cleaning, and requirement can control the circulating direction (namely adopting the ultra-clean device of laminar flow) of air-flow, air-flow is made to flow to the low region of cleanliness factor from the operative region that cleanliness factor is high, and the dust granules (grit) taken away and discharge in air-flow and bacterium.
But the new wind of the general all a large amount of unified employings of existing clean operating room, which increases the filtration burden of laminar flow air-blow ceiling, indoor cleanliness factor also can be caused to be restricted, and noise is large simultaneously.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, mute type self-circulation type clean operating room of the present utility model, to comprise and civil engineering wall 100 keeps interval 200 and the framed side wallboard 1 be fixedly connected with column, the top board 2 be fixedly connected with crossbeam, and three dimensional angular 3, be fixedly installed on the laminar flow air-blow ceiling 4 in the middle part of described top board, the air inlet of described laminar flow air-blow ceiling is provided with high efficiency particulate air filter 5, to be arranged on bottom framed side wallboard and in it, to be provided with the return air inlet 6 of just effect or medium effeciency filter, be communicated with each return air inlet 6 and laminar flow air-blow ceiling air inlet and be positioned at the circulating line 7 at described interval, and be serially connected on described circulating line in order to impel air to circulate and the blowing unit 8 be fixedly connected with described civil engineering wall, and the fresh air pipeline 9 that controlled with described blowing unit air intake is communicated with, described circulating line is divided into air supply duct and return air duct two parts by blowing unit, return air duct and fresh air pipeline also access the air intake of blowing unit, wherein, fresh air pipeline is provided with valve to control its opening time and open degree.
Civil engineering wall refers to the body of wall that civil construction builds up, be generally xoncrete structure, namely, clean operating room is embedded in the room body of a civil engineering, wherein, described clean operating room comprises the column 10 be fixedly connected with ground by footing, forms the crossbeam of clean operating room top frame by upright supports, and forms the framed side wallboard of clean operating room locular wall, top board and three dimensional angular.Specifically, described blowing unit comprises noise reduction box 15, the blower fan 17 be fixedly installed in noise reduction box, the air inlet of described blower fan and air outlet respectively with circulating line through one section of flexible pipe 16, as the connection such as sebific duct or bellows.Wherein, described noise reduction box to be fixedly installed on civil engineering wall and to be airtight casing, and the wall of casing is provided with sound-absorbing material.Be fixed on civil engineering wall, and framed side wallboard keeps interval, the transmission shaken can be avoided, reduce room noise and pollute, meanwhile, utilize the acoustically effective of sound-absorbing material, utilize the partition effect of flexible pipe to reduce the transmission of vibrations along circulation line, indoor quiet requirement can be ensured.
Wherein, the magnitude setting of return air inlet and the quantity one_to_one corresponding of laminar flow air-blow ceiling air inlet, that is, a pair return air inlet of correspondence is communicated with air inlet by each circulating line, simultaneously, a blowing unit is set in each circulation air path, independent circuit design, effectively reduces the windage in pipeline, adopts low power blower fan, the noise of effective control produces, and is conducive to the control of cost simultaneously.Certainly, both sides also can be adopted to arrange a set of blowing unit respectively, and namely both sides carry out collective's wind circulation respectively, or adopt two or three one group to carry out grouping Inner eycle.
For improving, the temperature of operation chamber interior is controlled, temperature control cavity 18 is serially connected with in described circulating line, temperature control assembly 19 is provided with in described temperature control cavity, as heat exchanger etc., described temperature control cavity can adopt insulation material to make, the corollary equipment of described heat exchanger is arranged on other regions or top, wherein improves the control of humidity, in each circulating line, also can arrange dehumidifier or humidifier.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
