Abstract

A blow-down system. The blow-down system is connected to a wastewater composite heat carrier generator (4). The wastewater composite heat carrier generator (4) comprises a generator body (42) and a generator head structure (20) connected below the generator body (42). A scale discharge passage (29) is disposed in the generator head structure (20). The blow-down system comprises a scale discharge manifold (8) communicating with the scale discharge passage (29). A slow scale storage chamber (81) is connected to the scale discharge manifold (8). A first scale discharge valve (82) is connected on the scale discharge manifold (8) between the slow scale storage chamber (81) and the scale discharge passage (29). Also provided is a blow-down method.

Abstract

A cooling and gasification device, a waste water composite heat carrier generator, and a composite heat carrier generation method. The waste water composite heat carrier generator comprises a generator body (42) and a generator head structure (20). The generator body (42) comprises a combustion chamber (41) and a steam chamber (43), and the upper end of the steam chamber (43) is connected to an outlet pipeline (431) and a cooling and gasification device (7). The generator head structure (20) is connected to the lower end of the generator body (42). A combustion nozzle, an ignition electrode, a water inlet channel (28) and a scale discharging channel (29) are disposed in a head body (2) of the generator head structure (20). In the waste water composite heat carrier, the requirements of high-pressure combustion and safe output of a composite heat carrier can be satisfied, meanwhile, waste water separated from crude oil can be used as cooling water to be subject to cooling treatment in the lower portion and the upper portion of the generator, and steam needed by the composite heat carrier is generated; and accordingly clean water resources are saved, and high cost of wastewater treatment can be reduced.

Abstract

A combustion nozzle, comprising: a nozzle body (1), one end thereof having a fuel inlet (11) and a pure oxygen inlet (12), and the other end thereof forming multiple diaphragm outer cavities (13). The interior of the nozzle body (1) is provided with a fuel passage (14) and a pure oxygen passage (15); one end of the fuel passage (14) is in communication with the fuel inlet (11), and the other end thereof is in communication with the multiple diaphragm outer cavities (13) by means of multiple inclined fuel holes (141); the inclined fuel holes (141) are radially and outwardly inclined along the ejection direction of fuel; one end of the pure oxygen passage (15) is in communication with the pure oxygen inlet (12), and the other end thereof is in communication with the multiple diaphragm outer cavities (13) by means of multiple inclined pure oxygen holes (151); the inclined pure oxygen holes (151) are radially and inwardly inclined along the ejection direction of pure oxygen. The combustion nozzle can uniformly atomize pure oxygen and natural gas, so that the uniformly atomized pure oxygen and natural gas are fully burned in a generator. Also disclosed are an ejection method of a combustion nozzle, a generator head construction, a pure oxygen composite heat carrier generator, and a method for generating a composite heat carrier.
