Detailed implementation mode

[0022] The following provides a preferred embodiment of the present invention in conjunction with the accompanying drawings to elaborate in detail on the technical solution of the present invention.

[0023] Figure 1 It is a schematic diagram of the overall structure of the present invention, as Figure 1 shown: The shared exhaust system for small gas generators provided by the present invention includes a first gas generator exhaust system and a second gas generator exhaust system, and the first gas generator exhaust system and the second gas generator exhaust system are symmetrically arranged; the first gas generator 1 and the second gas generator 2 are both connected to the main pipeline of the waste gas collection pipeline by pipelines. The first gas generator 1 and the second gas generator 2 enter the main pipeline of the exhaust pipeline. The first gas generator 1 and the second gas generator 2 are provided with air extraction bypasses. Sealing butterfly valves are added before and after the main pipeline and the air extraction bypass. The air extraction bypass uses an air amplifier, and a drain butterfly valve is arranged behind the air amplifier.

[0024] The first gas generator exhaust system includes: a first air amplifier 3, a first front exhaust butterfly valve 5, a first rear exhaust butterfly valve 6, a first drain butterfly valve 7, and a first inlet air balloon valve 8; the first front exhaust butterfly valve 5 and the first rear exhaust butterfly valve 6 are installed on the pipeline between the first gas generator 1 and the main pipeline of the waste gas collection pipeline. A branch pipeline is separated from the pipeline between the first front exhaust butterfly valve 5 and the first rear exhaust butterfly valve 6, and the first air amplifier 3 is installed on the separated branch pipeline; a first inlet air balloon valve 8 is arranged on the pipeline of the compressed air inlet section of the first air amplifier 3, and a first drain butterfly valve 7 is arranged on the pipeline of the flue gas exhaust section.

[0025] The second gas generator exhaust system includes: a second air amplifier 4, a second front exhaust butterfly valve 9, a second rear exhaust butterfly valve 10, a second drain butterfly valve 11, and a second inlet air balloon valve 12; the second front exhaust butterfly valve 9 and the second rear exhaust butterfly valve 10 are installed on the pipeline between the second gas generator 2 and the main pipeline of the waste gas collection pipeline. A branch pipeline is separated from the pipeline between the second front exhaust butterfly valve 9 and the second rear exhaust butterfly valve 10, and the second air amplifier 4 is installed on the separated branch pipeline; a second inlet air balloon valve 12 is arranged on the pipeline of the inlet section of the second air amplifier 4, and a second drain butterfly valve 11 is arranged on the pipeline of the exhaust section.

[0026] In the present utility model, the air amplifier is made of stainless steel, and the compressed air connecting pipe is a stainless steel pipe.

[0027] In the present utility model, the specifications and models of the two generators should be the same to avoid large backpressure deviation during operation, which may cause difficulty in exhausting gas for a single generator.

[0028] The main exhaust pipeline and bypass butterfly valve of the generator should both adopt high-temperature resistant butterfly valves, with a heat resistance temperature not lower than 700 °C, and the valve opening and closing adopt pneumatic or electric forms.

[0029] The air amplifier is made of stainless steel, and its exhaust flow rate is greater than the leakage of the main pipeline valve. The compressed air inlet pipe and ball valve are both made of stainless steel.

[0030] The working process of the system of the present utility model is as follows: When the first generator 1 and the second generator 2 operate simultaneously, close the first bypass exhaust butterfly valve 7 and the second exhaust butterfly valve 11, as well as the first compressed air inlet ball valve 8 and the second compressed air inlet ball valve 12; open the first front exhaust butterfly valve 5, the first rear exhaust butterfly valve 6, the second front exhaust butterfly valve 9, and the second rear exhaust butterfly valve 10, so that the exhaust gas of the two generators converges into the exhaust gas collection pipeline; when only one generator is turned on, taking the first generator 1 being turned on and the second generator 2 being turned off as an example, at this time, open the first front exhaust butterfly valve 5 and the first rear exhaust butterfly valve 6, the second exhaust butterfly valve 11, and the second compressed air inlet ball valve 12, and keep the other valves closed. Most of the exhaust gas of the first generator 1 directly enters the exhaust gas collection pipeline, and a small part flows back to the bypass of the exhaust pipe of the second generator 2. The residual gas in the second generator 2 also enters the bypass of the exhaust pipe and is exhausted by the second air amplifier 4; through the above operations, it is avoided that when operating alone, the flue gas flows back to another unit, causing flue gas corrosion to the other unit.

[0031] The shared exhaust system for small gas generators provided by the present utility model, while adopting valve sealing, additionally sets up a bypass air amplifier for air extraction, so that the exhaust gas leaked from the valve of the generator can be timely extracted and exhausted, avoiding corrosion of the generator cylinder block and ensuring equipment safety.
