Said supercharging device is a blower.
Owing to adopt above-mentioned technological means, make to the utlity model has following beneficial effect:
1, can realize the recovery of small malleation discharging gas is convenient to second use, and is reduced the pollution to atmosphere environment;
2, simple in structure, need not existing torch airing system is transformed, investment and operating cost are low;
3, automaticity is high, guarantees that equipment pressure in normal range (NR), satisfies the discharging back pressure requirement of manufacturing equipment.
Description of drawings
Fig. 1 is the structural representation of the recovering device of a kind of micro positive pressure discharging of the utility model gas.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing, it should be noted that and can not confirm the utility model claims scope required for protection with following embodiment.
As shown in Figure 1, the recovering device for a kind of micro positive pressure discharging of the utility model gas comprises collecting container 2, blower 3, one-way valve 4; Collecting container 2 is communicated with manufacturing equipment 1 through a collecting pipe 21, and the input end of blower 3 is communicated with collecting container 2 through exhaust tube 31, between the torch blow-down pipe 7 of blower 3 and factory, is provided with a pneumatic tube 5; Concrete is; One end of pneumatic tube 5 is communicated with the output terminal at blower 3, and the other end is communicated with the input end at torch blow-down pipe 7, and; On pneumatic tube 5, one one-way valve 4 and operating valve 51 is installed successively along gas flow; In addition; Above-mentioned recovering device also includes a reflow pipe 6; Its input end is connected on the pneumatic tube 5, and the on positi of itself and pneumatic tube 5 is between one-way valve 4 and operating valve 51, and the output terminal of reflow pipe 6 is communicated to the upper end portion of collecting container; In order to control effectively, a return valve 61 is installed also on reflow pipe 6 to capacity of reflux.
In order to realize intelligent control; Above-mentioned recovering device also comprises a controller and detection unit, and controller is mainly used in control return valve 61 and blower 3, and detection unit then is used for detecting in real time the force value of collecting container 2; And the signal output part of detection unit is connected on the controller.
In some cases; Low pressure discharging gas by manufacturing equipment 1 discharging can have certain temperature; To this situation; Can a cooler be installed on above-mentioned exhaust tube 31, cooler carries out cooling processing to the gas that passes through via exhaust tube 31, so that follow-up pressurized treatment can reach better effect.
The collecting container 2 of the utility model is collected to the low pressure discharging gas of manufacturing equipment 1; Itself and the mode that is not limited to being communicated with of manufacturing equipment 1 be communicated with collecting pipe 21; Can select comparatively suitable Placement for use, for example according to actual conditions; Under the situation of manufacturing equipment 1, can the low-pressure gas exhaust outlet of manufacturing equipment 1 directly be communicated with on collecting container 2 and get final product apart from collecting container 2 close together.
Collecting container 2 can adopt common horizontal pressurized tank or vertical pressure jar, in order to guarantee Security, relief valve is installed above that.
Above-mentioned recovering device is when work, by the low pressure discharging gas of collecting container 2 collection process equipment 1 discharging, when the pressure of detection in collecting container 2 reaches predetermined value; Controller control blower 3 is opened; Extract and discharge gas in the collecting container 2 and these discharging gas are increased to certain pressure (promptly being applicable to the force value of torch airing system), the discharging gas after the supercharging is transported to torch blow-down pipe 7 via one-way valve 4, enters into gas holder 8 then and reclaims; This state is the normal state to torch blow-down pipe 7 air feed; It should be noted that under this state return valve 61 state that keeps shut.
In blower 3 runnings; When the pressure of detection in collecting container 2 is lower than the certain pressure value; Controller control recycle control valve 61 is opened, and the discharging gas that is pressurized is back in the collecting container 2 through reflow pipe 6 again, is adjusted to normal range (NR) in order to the pressure with collecting container 2; After the pressure in the collecting container 2 was adjusted to normal range (NR), controller control recycle control valve 61 was closed condition.
Found out that by above above-mentioned blower 3 mainly plays the pressurization of gas, therefore, it can also adopt other supercharging equipment replacements.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technological scheme and the design of above description.
