Description
技术领域technical field
本实用新型涉及油气田地面工程技术领域，特别涉及油田污水处理，是一种用于油气田生产中污水回注的自清洁式沉砂过滤器。 The utility model relates to the technical field of oil and gas field surface engineering, in particular to oil field sewage treatment, and is a self-cleaning sand settling filter used for sewage reinjection in oil and gas field production. the
背景技术Background technique
目前，在油气田生产过程中，由于产生大量的污水需要处理，同时由于环保要求不能任意排放，只能通过污水回注地层的方式解决污水问题。在污水回注过程中，由于污水中存在砂子及结晶等，经常引起滤网被堵塞，需要频繁清洗滤网，不仅费工费时，而且影响正常回注效果，堵塞地层。 At present, in the production process of oil and gas fields, due to the large amount of sewage that needs to be treated, and due to environmental protection requirements, it cannot be discharged arbitrarily, so the sewage problem can only be solved by reinjecting sewage into the formation. In the process of sewage reinjection, due to the presence of sand and crystals in the sewage, the filter screen is often blocked, and the filter screen needs to be cleaned frequently, which is not only labor-intensive and time-consuming, but also affects the normal reinjection effect and blocks the formation. the
实用新型内容Utility model content
本实用新型的目的是：提供一种自清洁式沉砂过滤器，能实现污水中存在砂子及结晶被过滤分离出来，并且滤网能实现自动清洁，减少人工清洗滤网。 The purpose of this utility model is: to provide a self-cleaning sand settling filter, which can realize the sand and crystals in the sewage to be filtered and separated, and the filter screen can realize automatic cleaning, reducing manual cleaning of the filter screen. the
本实用新型采用的技术方案是：自清洁式沉砂过滤器，主要由过滤网、过滤器主罐和储砂罐组成，在过滤器主罐的顶部固定有罐顶(封头)，在过滤器主罐的侧壁上固定有入水口，其特征在于：在过滤器主罐内上部固定有的过滤网，在过滤器主罐顶部的罐顶上固定有出水口。在过滤器主罐的下部连接有密闭的储砂罐，在储砂罐的侧壁上固定有排砂口。 The technical solution adopted in the utility model is: a self-cleaning sand settling filter, which is mainly composed of a filter screen, a filter main tank and a sand storage tank, and a tank top (sealing head) is fixed on the top of the filter main tank. A water inlet is fixed on the side wall of the main tank of the filter, and it is characterized in that: a filter screen is fixed on the upper part of the main tank of the filter, and a water outlet is fixed on the top of the main tank of the filter. A closed sand storage tank is connected to the lower part of the filter main tank, and a sand discharge port is fixed on the side wall of the sand storage tank. the
所述的入水口、出水口和排砂口上连接有阀门。 Valves are connected to the water inlet, water outlet and sand discharge port. the
所述的过滤器主罐为圆柱体罐，过滤器主罐罐体的下部是漏斗形。 The filter main tank is a cylindrical tank, and the lower part of the filter main tank body is funnel-shaped. the
所述的入水口是斜向下固定在过滤器主罐的侧壁上。 The water inlet is fixed obliquely downward on the side wall of the filter main tank. the
简述自清洁式沉砂过滤器的工作原理：参阅图1。过滤网3安装在入水口1上方并在出水口的下方。含砂污水从入水口1进入后，在过滤器主罐4中产生水砂分离，部分砂子下沉到储砂罐5，同时还有部分砂子在液体的带动下向上运动，经过过滤网3时由于砂子不能通过过滤网3而被拦阻在过滤网3的下部，过滤网3上的砂子积累后下沉到储砂罐5中，过滤出来的砂自动下沉不会堵塞过滤器。液体则顺利通过过滤网3向上运动通过出水口2，从而保证输出的水是不含砂子的合格水，储砂罐中的砂子要定期通过排砂口6排出。过滤网3制作材质可采用不锈钢、碳钢等。封头与主体采用螺栓连接。 Briefly describe the working principle of the self-cleaning grit filter: see Figure 1. The filter screen 3 is installed above the water inlet 1 and below the water outlet. After the sandy sewage enters from the water inlet 1, water and sand are separated in the filter main tank 4, and part of the sand sinks to the sand storage tank 5, and at the same time, part of the sand moves upwards driven by the liquid, and passes through the filter screen 3 Because the sand cannot pass through the filter screen 3 and is blocked at the bottom of the filter screen 3, the sand accumulated on the filter screen 3 will sink in the sand storage tank 5, and the filtered sand will sink automatically and will not block the filter. The liquid moves upwards through the filter screen 3 smoothly through the water outlet 2, thereby ensuring that the output water is qualified water without sand, and the sand in the sand storage tank will be discharged through the sand discharge port 6 on a regular basis. The filter screen 3 can be made of stainless steel, carbon steel or the like. The head and the main body are connected by bolts. the
本实用新型的有益效果：本实用新型自清洁式沉砂过滤器，能实现污水过滤处理，过滤出来的砂自动下沉不会堵塞过滤器。能减少人工清洗滤网，操作方便，成本低廉。 Beneficial effects of the utility model: the self-cleaning sand settling filter of the utility model can realize sewage filtration treatment, and the filtered sand will sink automatically without blocking the filter. It can reduce manual cleaning of the filter screen, and is easy to operate and low in cost. the
