Embodiment Construction
[0012] A cryogenic decoking method, comprising filtering, washing processes, and a cryogenic treatment step, the cryogenic treatment step is carried out with a special device for cryogenic decoking, and the steps are as follows: (1) the cooling liquid that is deeply cooled by a refrigeration unit, Circulation is carried out in the cooling pipe of the condenser; (2) after filtering, the stalk gas washed with water flows through the annular space between the inner pipe and the outer pipe of the condenser for heat exchange to achieve complete decoking and dehydration; (3) The decoking and dehydrating standard straw gas is discharged from the outlet pipe, and the detached tar and water flow out through the liquid removal tank.
[0013] The cooling liquid in step (1) is pumped by the cooling liquid pump, refrigerated by the refrigeration unit, enters the condenser through the box body and the cooling liquid filter, and circulates. The straw gas is passed through the annular space o...

The invention relates to a deep cooling decoking method and a device. The method comprises a filtration process and a washing process and also a deep cooling treatment procedure. The deep cooling treatment procedure is dealt by a deep cooling decoking special device with the procedures as follows: firstly, the cooling liquid deeply cooled by a refrigeration unit circulates inside a condensater heat dispersing pipe; secondly, after filtration, water washing straw gas flows through the annular space between the internal and external tubes of the condensater and exchanges heat to realize thorough decoking and dehydration; thirdly, the decoking and dewatering standard straw gas is exhausted through an air outlet pipe and the decoked tar and water are flown out through a liquid exhaust tank. The device comprises an air inlet pipe, a condensater, a liquid exhaust tank, a bracket filter, an air outlet pipe, a cooling liquid filter, a box body, a refrigeration unit, a cooling liquid pump, and a gate valve; wherein, the liquid exhaust tank is arranged on the bracket, the condensater and the filtrter are respectively arranged on both ends of the liquid exhaust tank, the filter is arranged with an air outlet pipe, the condensater is arranged with the air inlet pipe and the cooling liquid cooling system.
Description
1. Technical field [0001] The invention relates to a decoking method and equipment for straw gas power generation, in particular to a cryogenic decoking method and device. 2. Background technology [0002] At present, domestic straw gas power generation progresses slowly, mainly due to the inability to solve the technical problem of high tar content. Straw gas purification generally uses methods such as filtration and water washing to remove tar, which can remove part of the tar and achieve certain results. However, the quality of straw gas after removal still cannot meet the requirements for power generation, and the incomplete removal of tar can easily cause problems such as pipeline blockage, which affects the normal operation of the generating set. 3. Contents of the invention [0003] The purpose of the present invention is to provide an improved cryogenic decoking method. On the basis of rough decoking methods such as filtering and washing straw gas, the method adop...
