The hot water main pipe transversely penetrates through one side of the water mixing tank, hot water in the hot water main pipe flows into the water mixing tank through the flow dividing pipe and is input through the hot water main pipe, then the hot water is discharged through the flow dividing pipe and collected around the hot water main pipe to form a hot water area, and correspondingly, the cold water main pipe outputs cold water, and the cold water is divided through the cold water thin pipe and finally sprayed through the spray head. A cold water layer is formed on the periphery of the hot water area for coating, and along with continuous injection of water heat, the water pressure of the hot water area is increased, so that the hot water and the cold water layer are mixed to form mixed water which diffuses towards the periphery, and finally the mixed water is pumped away by the water outlet branch pipes and discharged for use.

Normal operation and safety of the boiler are guaranteed, the pre-cooling mechanism receives hot water discharged from the steam boiler, and the hot water is prevented from directly entering the cooling tower, so that the load of the cooling tower is reduced, the hot water is changed into small liquid drops, the contact area of the hot water and a cooling medium is increased, heat dissipation is accelerated, and the pre-cooling efficiency is improved.

This invention belongs to the field of water circulation technology, and particularly relates to a non-discharge cold-point water-for-injection circulation system, comprising: a water storage tank for storing water for injection; and a circulating water pump installed on one side of the water storage tank. The circulating water pump, after being cooled by a heat exchange structure, is returned to the main pipeline via a branch pipe and then flows back into the water storage tank through a connecting pipe, avoiding direct discharge of low-temperature water for injection. This solves the problem of water loss in traditional discharge schemes, reduces the production costs of pharmaceutical companies, and forms a closed loop between the main pipeline and the water storage tank. The branch pipe is connected to the main pipeline through a heat exchange structure, and all return water from the usage points returns to the main pipeline. At the same time, the circulating water pump drives the water flow circulation, ensuring that the flow velocity in the main pipeline meets the subsequent turbulence requirements, inhibiting microbial growth. Several cooling points are set up to support the simultaneous use of single or multiple cooling points, adapting to the room temperature or low temperature water-for-injection needs of different scenarios such as bottle washing machines, ultrafiltration, and disinfectant preparation, thus improving the system's versatility.

The invention relates to the technical field of mass concrete temperature control, aims to overcome the defects in a traditional temperature control water circulation technology, and particularly relates to a mass concrete cooling water adjusting method based on the temperature difference between the water temperature of a water tank and concrete water. Comprising the following steps that S1, the highest temperature Tmax in concrete and the water inlet temperature Tin of a water tank are collected in real time, and the starting water temperature Tst is set; s2, whether the conditions that Tin is larger than Tst and Tmax-Tin is smaller than delta T are met at the same time or not is judged, wherein delta T is the target concrete-water temperature difference; if not, the automatic water supplementing and draining configuration is not started; if yes, continuing the next step; s3, expected water supplementing and draining duration is set, water is drained to the lowest water level of the water tank, and then water is supplemented to the highest water level of the water tank; and S4, returning to S2 for circulation. Temperature matching has timeliness, short-time, high-frequency and automatic water replenishing can be carried out according to the internal temperature field of the concrete, and the situation that the cooling effect of the concrete is affected due to cooling water temperature regulation hysteresis caused by manual water replenishing is avoided.

The application discloses a boiler environment-friendly induced draft fan cooling circulating water system and belongs to the technical field of cooling water circulation, which comprises a normal water circulating device and an emergency water circulating device. When the normal water circulating device operates, the water outlet pipe is communicated with the water supply pipe, water in the water tank is introduced into the water supply pipe from the water outlet pipe, and then is drained into the cooling assembly from the water supply pipe. The water absorbs heat in the cooling assembly and cools the induced draft fan. The heat-absorbed water is returned to the inside of the water tank from the return pipe, and the induced draft fan is cooled in circulation. When the emergency water circulating device operates, the emergency pipe is communicated with the water supply pipe, and the emergency pipe provides water source for the water supply pipe. At this time, the water supply pipe is drained into the cooling assembly from the water supply pipe. After the water absorbs heat in the cooling assembly and cools the induced draft fan, the heat-absorbed water is returned to the inside of the water tank 1, so that a complete emergency water circulation is completed, and the induced draft fan is not damaged due to untimely cooling after a sudden power failure, thereby ensuring the normal operation of the induced draft fan.
