本发明的冷却气化装置7用于向蒸气室43的蒸气气化腔433内喷射水流，具体的，该水流为废水水流，该废水为原油开采中油水分离后的废水。通过该冷却气化装置7向废水复合热载体发生器内喷射废水，一方面用于冷却发生器，另一方面，自冷却气化装置7喷入蒸气气化腔433内的废水会吸收废水复合热载体发生器的热量而生成高温蒸气，该高温蒸气与蒸气环腔433内的蒸气和燃烧室41内的燃料燃烧后生成的气体共同掺混形成复合热载体。该冷却气化装置7节约了水处理成本，避免了原油分离废水的直 接排放，实现了多元热流体技术在油砂低成本开采中的应用。The cooling gasification device 7 of the present invention is for injecting a water flow into the vapor gasification chamber 433 of the vapor chamber 43. Specifically, the water flow is a wastewater water flow, which is a waste water after oil and water separation in crude oil production. The wastewater is sprayed into the wastewater composite heat carrier generator by the cooling gasification device 7, and is used to cool the generator on the one hand. On the other hand, the wastewater injected into the vapor gasification chamber 433 from the cooling gasification device 7 absorbs the wastewater composite. The heat of the heat carrier generator generates high temperature vapor which is blended with the vapor in the vapor ring chamber 433 and the gas generated after combustion of the fuel in the combustion chamber 41 to form a composite heat carrier. The cooling gasification device 7 saves the water treatment cost and avoids the straightness of the crude oil separation wastewater. The discharge is realized, and the application of multi-component thermal fluid technology in low-cost mining of oil sands is realized.
具体是，该冷却气化装置7包括多组喷水组件71，每组喷水组件71包含两个喷水头711，该两个喷水头711对称连接在发生器本体42的蒸气室43径向方向相对的两侧，且该两个喷水头711与蒸气室43的蒸气气化腔433相连通。Specifically, the cooling gasification device 7 includes a plurality of sets of water spray assemblies 71, each set of water spray assemblies 71 including two water spray heads 711, which are symmetrically connected to the steam chamber 43 of the generator body 42. The two spray heads 711 are in communication with the vaporization chambers 433 of the vapor chamber 43 in opposite directions.
如图2所示，每组喷水组件71的两个喷水头711之间连接有一个冷却水管72，该冷却水管72与外部废水源相连通。在本实施例中，外部废水源中的废水为原油开采中油水分离后的废水。As shown in Fig. 2, a cooling water pipe 72 is connected between the two water spray heads 711 of each group of water spray assemblies 71, and the cooling water pipes 72 are in communication with an external waste water source. In this embodiment, the wastewater in the external wastewater source is the wastewater after the separation of the oil and water in the crude oil production.
当外部废水源通过冷却水管72向一组喷水组件71的两个喷水头711注入废水时，两个喷水头711由于沿蒸气气化腔433的径向相对设置，因此，自两个喷水头711喷出的废水会在蒸气气化腔433的中心，也即燃烧室41的正上方对撞掺混并吸收热量，瞬间形成水雾而生成高温蒸气，该高温蒸气与来自燃烧室41的燃料燃烧后的气体以及蒸气环腔432中废水吸热后形成的蒸气三者掺混形成复合热载体。When the external waste water source injects the waste water into the two spray heads 711 of the water spray chambers 71 through the cooling water pipes 72, the two water spray heads 711 are disposed opposite each other in the radial direction of the vapor gasification chamber 433, and therefore, The waste water sprayed from the water spray head 711 collides and absorbs heat in the center of the vapor gasification chamber 433, that is, directly above the combustion chamber 41, and instantaneously forms a water mist to generate high temperature steam, which is from the combustion chamber. The gas after combustion of the fuel of 41 and the vapor formed by the heat absorption of the waste water in the vapor ring chamber 432 are mixed to form a composite heat carrier.
在本发明的一实施例中，在蒸气室43的外壁上沿其圆周方向间隔设置有多组喷水组件71，且多组喷水组件71位于同一水平面上。这样可使自多组喷水组件71中的多个喷水头711喷出的废水集中于蒸气气化腔433的中心对撞，一方面用于形成水雾，另一方面可使燃烧室41的燃料燃烧后的气体与废水吸收后形成的蒸气均匀掺混。在本实施例中，在蒸气室43上端沿其圆周方向设有2组～4组喷水组件71。In an embodiment of the invention, a plurality of sets of water spray assemblies 71 are disposed on the outer wall of the vapor chamber 43 at intervals in the circumferential direction thereof, and the plurality of sets of water spray assemblies 71 are located on the same horizontal surface. In this way, the waste water discharged from the plurality of spray heads 711 in the plurality of sets of water spray assemblies 71 can be concentrated in the center of the vapor gasification chamber 433, on the one hand for forming water mist, and on the other hand, the combustion chamber 41 can be used. The fuel after combustion of the fuel is uniformly blended with the vapor formed by the absorption of the wastewater. In the present embodiment, two groups to four sets of water spray assemblies 71 are provided at the upper end of the vapor chamber 43 along the circumferential direction thereof.
在本发明的一实施例中，如图3所示，该喷水头711具有水流通道712，该水流通道712的入口端713直径是水流通道712的出口端714直径的3倍。进一步的，该水流通道712靠近其出口端714处设有直径减缩段715。在本实施例中，水流通道712的入口端713的直径为1.5mm～3.5mm。In an embodiment of the invention, as shown in FIG. 3, the water jet head 711 has a water flow passage 712 having an inlet end 713 having a diameter three times the diameter of the outlet end 714 of the water flow passage 712. Further, the water flow channel 712 is provided with a diameter reduction section 715 near its outlet end 714. In the present embodiment, the inlet end 713 of the water flow passage 712 has a diameter of 1.5 mm to 3.5 mm.
该直径减缩段715为形成在水流通道712内的圆台体形通道，该直径减缩段715为自入口端713向出口端714的方向，通道的直径呈逐渐收缩状，本发明在喷水头711的水流通道712内采用直径减缩段715的设计，可以使自水流通道712的入口端713流入水流通道712的出口端714的废水水流形成射流，以便吸收蒸气室43内的热量，且减低喷水头711的出口端714温度。The diameter reduction section 715 is a truncated cone shaped passage formed in the water flow passage 712. The diameter reduction section 715 is in the direction from the inlet end 713 to the outlet end 714, and the diameter of the passage is gradually contracted. The present invention is in the water spray head 711. The design of the diameter reduction section 715 is employed in the water flow passage 712 to allow the waste water flow from the inlet end 713 of the water flow passage 712 to the outlet end 714 of the water flow passage 712 to form a jet to absorb heat in the vapor chamber 43 and reduce the water spray head. The outlet end 714 of 711 is at a temperature.
进一步的，该水流通道712的出口端714形成有弧形倒角外周缘716，也即，在出口端714的外边缘形成一圈弧形倒角结构，这样可防止自喷水头711喷射的废水在喷水头711的出口端714形成结垢，同时该弧形倒角外周缘716的喷口加工端面及水流通道712的内表面粗糙度低，使废水流过时表面光滑，以进一步防止结垢。 Further, the outlet end 714 of the water flow channel 712 is formed with an arcuate chamfered outer circumference 716, that is, a circular chamfered structure is formed at the outer edge of the outlet end 714, thereby preventing the ejection from the water jet head 711. The wastewater forms fouling at the outlet end 714 of the water jet head 711, and the nozzle processing end surface of the curved chamfer outer peripheral edge 716 and the inner surface roughness of the water flow passage 712 are low, so that the surface of the waste water flowing through is smooth, so as to further prevent scaling. .
