Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a circulating water treatment device for liquefied natural gas production. Background Art

[0002] The main component of liquefied natural gas is methane, which is colorless, odorless, non-toxic and non-corrosive. Liquefied natural gas needs to adjust the temperature when it is produced. At present, it is mostly achieved through circulating water treatment devices. The working principle of the existing circulating water treatment device is to extract water from the water tank through a water pump, and input the water into the working tank through the water supply pipe, and then spray it out through the nozzle. The sprayed water falls into the water tank through the pipe. When the water falls from the working tank into the water tank, some impurities will be brought in, which will cause equipment blockage after long-term use. Therefore, the existing circulating water treatment device is equipped with a dosing mechanism. By adding medicine into the water and stirring it through a stirring mechanism, the medicine is mixed into the water to eliminate bacteria and prevent blockage. In addition, a filter is set in the water tank to filter impurities in the circulating water, prevent pipeline blockage, and concentrate impurities. This realizes the recycling of water and can complete the production of liquefied natural gas.

[0003] For example, the patent with publication number CN215161682U discloses a circulating water treatment device for liquefied natural gas production, including a bracket, a working tank is fixedly installed at one end of the bracket, a water tank is fixedly connected to the bottom of the working tank, a filter is detachably installed inside the water tank, a medicine adding box is welded on one side of the top of the water tank, and a support plate is fixedly installed inside the medicine adding box. In the above scheme, after the valve is opened, the medicine will fall on the weight sensor through the medicine dispensing pipe and the first hose, and the weight sensor can sense the weight of the medicine falling on its top. When the weight is about to reach the requirement, the medicine dispensing valve is controlled to close slowly, so that the amount of medicine when the medicine dispensing valve is closed just meets the requirement, and then the first electric telescopic rod is controlled to drive the block to rise, so that the medicine can fall into the water tank through the first through groove, the medicine dispensing groove and the medicine dispensing port, thereby realizing accurate control of the amount of medicine added, avoiding too little or too much medicine, and ensuring that the amount of medicine added can meet the requirements.

[0004] After long-term use of the existing treatment device, some debris will accumulate on the filter screen, affecting the filtering effect. The existing device cannot clean the filter screen well. Therefore, a circulating water treatment device for liquefied natural gas production is proposed to solve the above problem. Utility Model Content
