Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of simple in construction, two grades of bittern purifying flue gas conveyer devices that cost of manufacture is low, and the using method of this conveyer device are provided, the phenomenon that salt can be avoided to flow backwards because of siphonage, prevents smoke conveying duct from bursting.
The technical solution adopted for the present invention to solve the technical problems is:
Two grades of bittern purifying flue gas conveyer devices of the one of the present invention, including flue gas compressor, at least 1 control valve and relief valve；Described flue gas compressor connects with flue gas delivery pipe, is delivered to bottom bittern purifying reaction container by the flue gas after compression；Described flue gas delivery pipe includes main flue gas conveying pipe and at least 1 flue gas delivery pipe, and described flue gas delivery pipe is provided with control valve；One end of described relief valve connects with main flue gas conveying pipe, its other end and atmosphere.
Further, the rated pressure of described relief valve is 0.2 ~ 0.3MPa.
Further, the end of described flue gas delivery pipe distance≤1.0m bottom bittern purifying reaction container.
The using method of a kind of two grades of bittern purifying flue gas conveyer devices, comprises the following steps:
1), before two grades of bittern purifyings, first open control valve, then, start flue gas compressor, flue gas can be passed through in bittern purifying reaction container and carry out bittern purifying；
2) after two grades of bittern purifying reactions terminate, first closing control valve, then, stop flue gas compressor, the flue gas in main flue gas conveying pipe, by relief valve releasing pressure automatically, keeps pressure stability in flue gas delivery pipe, prevents pipe bursting.
When quantity >=2 of control valve, the concrete operations of control valve be open simultaneously or according to purify reaction need open in batches；Simultaneously close off or close in batches according to purifying extent of reaction in purifying reaction container.
The beneficial effect of a kind of two grades of bittern purifying flue gas conveyer devices of the present invention: simple in construction, cost of manufacture is low, can be prevented effectively from the phenomenon that salt in bittern purifying reaction container occurs to flow backwards under siphonage, extend the service life of flue gas compressor.
The beneficial effect of the using method of a kind of two grades of bittern purifying flue gas conveyer devices of the present invention: change the operational approach of flue gas conveyer device in prior art, thoroughly solve two grades of bittern purifying flue gas conveyer devices in prior art and there is the difficult problem that salt refluence causes flue gas compressor to be damaged, use relief valve, maintain pressure stability in flue gas delivery pipe, avoiding stopping in venting process, there is the phenomenon of pipe bursting because of pressure abruptly increase in flue gas delivery pipe.
