Problems solved by technology

[0003] The casing cooler is not suitable for the situation of large flue gas volume and large cooling range; most of the common flue gas water coolers on the market currently use close-packed tube coolers, the water goes through the tube side, and the flue gas goes through the shell side, relying on the inside of the tube The flowing water takes away the heat, and the heat exchange efficiency is high. However, a large number of tube bundles and water in the tube bundles cause the overall operation quality of the equipment to be relatively high. The requirements for the sealing of the heat exchange tubes and equipment are high. Once water leakage occurs, the entire cooler will be damaged. Cannot be used, or even affect the operation of the rear equipment

specific Embodiment 1

[0034] see figure 1 , Figure 3-4 , is a liquid-holding water cooling device, including more than one heat exchange tube 1 and a liquid-holding area 2 arranged on the upper periphery of the heat-exchange tube 1, and more than one heat-exchange tube 1 is provided with the liquid-holding area 2 is connected to the through hole 3, and the liquid holding area 2 is connected to the water pump through the pipeline.

[0035] In this embodiment, the liquid holding area 2 is an open environment, and the system can be in a dynamic equilibrium state at normal pressure through the cooperation of the liquid level detection device and the flow control valve. The water on the inner wall of the heat exchange tube 1 is in a state of natural flow, even if the heat exchange tube A small damage to the wall will not affect the operation of the entire equipment, reducing welding and sealing requirements, and normal pressure operation can make the equipment have a longer service life.

[0036] In ...

specific Embodiment 2

[0047] see figure 2 , Figure 3-4, the difference from the specific embodiment 1 is that in this embodiment, a liquid level gauge 6 is arranged in the liquid holding area 2, and a flow meter 4 and a water inlet valve 5 are arranged on the pipeline connected to the water pump. In step S2, according to Pipe flow or liquid level height adjusts the opening of water inlet valve 5, thereby controlling the height of the liquid level in the liquid holding area 2.

[0048] The flue gas of the present invention passes outside the pipe, and the cooling water flows naturally from top to bottom along the inner wall of the heat exchange pipe 1 through the through hole 3 on the heat exchange pipe 1 to take away heat. Effectively reduce the weight of water in the entire operating system, making the weight of the entire equipment smaller; the entire system is in a state of normal pressure, even if there is a small damage to the wall of the heat exchange tube 1, it will not affect the operati...

Abstract

The invention belongs to the field of flue gas cooling, and relates to a liquid-holding flowing water cooling device and method. The liquid-holding flowing water cooling device comprises more than one heat exchange tube and a liquid-holding area arranged on the periphery of the upper part of the heat exchange tube, and more than one through hole communicating with the liquid-holding area is formed in the heat exchange tube. According to the device, cooling water naturally flows along the inner wall of the heat exchange tube from top to bottom through the through holes in the heat exchange tube to take away heat outside a flue gas passing tube; the weight of water in the whole operation system is effectively reduced, so that the weight of the whole equipment is smaller; and the whole system is in a normal pressure state, even if the wall of the heat exchange tube is slightly damaged, the operation of the whole equipment is not influenced, the welding and sealing requirements are reduced, and the equipment manufactured according to the principle can obtain longer service life.

Description

technical field [0001] The invention belongs to the field of flue gas cooling, and relates to a liquid-holding and flowing water cooling device and method. Background technique [0002] Indirect water cooling is a cooling device in which the high-temperature flue gas transfers heat through the heat exchange tube wall, and the heat is taken away by the water flowing in the cooler or the interlayer. Commonly used flue gas water cooling devices include water-cooled sleeves and close-packed pipes type water cooler. The advantage of water cooling is that the high-temperature flue gas can make full use of its heat energy while cooling the flue gas, and can realize the recovery and utilization of waste heat. [0003] The casing cooler is not suitable for the situation of large flue gas volume and large cooling range; most of the common flue gas water coolers on the market currently use close-packed tube coolers, the water goes through the tube side, and the flue gas goes through t...
