Detailed description of the invention
Below in conjunction with accompanying drawing, emission-control equipment of the present invention is described in further detail.
As shown in Figure 1, emission-control equipment of the present invention, comprising: emission-control equipment of the present invention, comprising: shell 1; Waste gas container 2, waste gas container 2 is arranged in shell 1, is provided with container waste gas of anesthesia import 3 and container waste gas of anesthesia outlet 4 in the bottom of waste gas container 2; Pressure modular converter, pressure modular converter is arranged in shell 1, and pressure modular converter is connected with appearance waste gas container 2 with container waste gas of anesthesia outlet 4 by container waste gas of anesthesia import 3; Flow meter modules, flow meter modules is arranged in shell 1, and flow meter modules is connected with pressure modular converter.
Pressure modular converter comprise mutually connect successively module base 5, module air chamber 6, module upper cover 7, positive pressuring film plate 8, negative pressure diaphragm 9, malleation valve gap 10 and negative pressure valve gap 11.Positive pressuring film plate 8 and negative pressure diaphragm 9 are column type, and positive pressuring film plate 8 material is copper, and negative pressure film sheet material is aluminum.Flow meter modules comprises flow meter body 12 and flow control valve 13.Module base 5 is divided into the first air chamber 17, second air chamber 18 and the 3rd air chamber 19, first air chamber 17 to be arranged on the side of module base 5; Second air chamber 18 and the 3rd air chamber 19 are set in parallel in the other side of module base 5; First air chamber 17, second air chamber 18 and the 3rd air chamber 19 are interconnected by pore.The outside of module base 5 also comprises: module waste gas of anesthesia enter 14 and module waste gas of anesthesia go out 15, module waste gas of anesthesia enters 14 and 15 to be communicated with negative pressure system with the outlet of module waste gas of anesthesia; Interface 16, flow meter body 12 and flow control valve 13 are connected in series with module base 5 by interface 16.
During work, waste gas of anesthesia enters exhaust device by module waste gas of anesthesia import 14, enters pressure modular converter, is provided with malleation relief valve in the air chamber be communicated with module waste gas of anesthesia import 14, and the diaphragm controlled pressure of malleation relief valve is 10cmH
2o, waste gas enters in container by the rear port of this air chamber again, the waste gas entered in container passes through buffering, under the effect of negative pressure system, 4 are exported out by the container waste gas of anesthesia in container, enter pressure modular converter again, pressure modular converter is divided into three parts: be divided into two parts on the right side of module base 5, the air chamber on the right side of module air chamber 6.This three parts air chamber passing hole communicates, waste gas by time certain back pressure is formed to negative pressure diaphragm.On the right side of module base 5, two parts respectively have interface 16, and for being connected in series effusion meter in gas circuit, effusion meter is divided into two parts: flow meter body 12 and flow control valve 13, discharge finally by module waste gas of anesthesia outlet 15, enter negative pressure system and concentrate purification.
As shown in Figure 2, be the duty of emission-control equipment when negative pressure system extraction flow is excessive.Excessive owing to extracting flow, when waste gas of anesthesia enters into pressure conversion module from waste gas container, the back pressure on negative pressure diaphragm is less than-0.3cmH
2o, negative pressure valve is opened, and air enters rapidly the negative pressure eliminated in gas circuit.Guarantee that anesthetic machine normally works.
As shown in Figure 3, being emission-control equipment extracts in the too small or pipeline of flow duty when having plugging fault at negative pressure system.Too small owing to extracting flow, the pressure increase in exhaust device gas circuit, waste gas of anesthesia enters pressure conversion module, when pressure reaches 10cmH by module waste gas of anesthesia import 14
2during O, positive valve diaphragm is opened, and waste gas enters air by the hole on malleation valve gap 10.Excess pressure in cancellation element, guarantees the normal work of anesthetic machine.
The waste gas that emission-control equipment of the present invention is collected and buffering anesthetic machine is discharged, and the operating pressure of anesthetic machine is not affected, purify the working environment of operating room, ensure that the safety of medical personnel's working environment.
Below the preferred embodiment of the invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
