Abstract: The present invention discloses a method for recycling heavy oil produced water for use in a steam injection boiler without desilication, comprising: the heavy oil produced water sequentially undergoes pre-treatment, filtration treatment and divalent and trivalent scaling ion removal by using a macroporous weak acid resin and the like. The method may reduce the concentration of the divalent and trivalent scaling ions in the heavy oil produced water to below 50 ?g/L, and can recycle high-silicon-containing heavy oil produced water for use in the steam injection boiler without desilication. Further disclosed is a system for recycling heavy oil produced water for use in a steam injection boiler without desilication.

Abstract: A method for deep removal of divalent and trivalent scaling ions from heavy oil produced water is described. The method comprises performing divalent and trivalent scaling ion deep removal treatment on heavy oil produced water by using a macroporous weak acid resin, to reduce divalent and trivalent scaling ions in the heavy oil produced water to 50 ?g/L. The water quality of produced water treated using the method is superior to the boiler water standard, a silicon removal process in a conventional heavy oil produced water treatment process can be cancelled, and significant economic benefits are achieved.

Abstract: A sampling assembly, including a sampling needle, a first pipeline, a second pipeline, a driving member, a first switching member, and a second switching member, is disclosed. The first pipeline is connected between the sampling needle and the first switching member. The second pipeline is connected between the first switching member and the driving member. The first switching member is used for connecting or disconnecting the first pipeline and the second pipeline. The second pipeline is connected, by means of the second switching member, to a negative pressure source. The sampling time of the sampling assembly of the present disclosure is relatively short. The present disclosure further discloses a sample analyzer and a sampling method.

Abstract: Disclosed in the present invention is a blood sample analyzer, including a sample conveying device, a first agitating device, a second agitating device and a controller, etc. When the first agitating device drives a sample container placed in a sample container accommodating hole to agitate a blood sample, a bottom of the sample container is kept lower than an opening of the sample container. In addition, the present invention further discloses a blood sample agitating device, a blood sample analysis method, a blood sample agitating method, and a computer storage medium.

Abstract: Disclosed is a blood sample analyzer, including: a sample conveying device for conveying a sample rack loaded with a sample container; a first agitating device having a sample stirring component for stirring a blood sample in the sample container and being capable of driving the sample stirring component to uniformly agitate the blood sample in the sample container; a second agitating device capable of picking up the sample rack or a second sample container on the sample rack, and driving the second sample container containing a common-volume blood sample on a second agitating position to uniformly agitate the blood sample; and a controller configured to communicate with the sample conveying device, the first agitating device and the second agitating device, and control the sample conveying device, the first agitating device and the second agitating device. In addition, the present application further discloses a blood sample agitating device, a blood sample analysis method, and a computer storage medium.

Abstract: A sample analyzer, comprising a reaction assembly and a detection assembly, wherein the reaction assembly comprises a sampler and a reaction tank, the sampler is used for collecting a biological sample and injecting the biological sample into the reaction tank, a wall of the reaction tank is provided with a first through-hole used for injecting a first reagent, and a center line of the first through-hole is arranged to be misaligned with the sampler after the sampler moves into the reaction tank, the detection assembly is connected to the reaction tank and is used for drawing fluid from the reaction tank for test. The reaction assembly enables a solution to be more uniformly mixed.
