Description

Technical Field

[0001] This utility model relates to the technical field of benzene removal devices, specifically a high-efficiency negative pressure benzene removal device. Background Technology

[0002] In modern industry, high-efficiency negative pressure benzene removal devices are widely used in gas processing systems to remove benzene pollutants from gases and ensure compliance with environmental protection requirements. The negative pressure benzene removal tower, as the core component of this device, primarily functions to remove benzene using steam. During operation, steam is piped into the tower, where it comes into contact with the gas to be treated, promoting the removal of benzene compounds.

[0003] However, in existing technologies, steam is prone to condensation into water droplets during transmission in cold winter environments due to the drop in external ambient temperature, thus reducing steam utilization efficiency. Specifically, when steam is transported from pipelines to the negative pressure benzene removal tower, the temperature of the steam may drop significantly during the transmission process due to the influence of the external environment, causing the steam to condense into water droplets. This not only affects the normal operation of the benzene removal tower but also increases the system's energy consumption and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency negative pressure benzene removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency negative pressure benzene removal device, comprising a tower body, an outer casing, and an inner casing. The top of the outer casing has a first cavity, the middle of the first cavity has an inner casing, and the bottom of the outer casing has a second cavity. A second pipe is fixed in the middle of the second cavity. One end of the second pipe is connected to one side of a first flange, and the other side of the first flange is connected to an interface, which is fixed to the bottom side of the tower body.

[0006] When using the high-efficiency negative pressure benzene removal device in this technical solution, the operator first needs to connect an external power supply to the device and control its operation through the control panel. The operator then replenishes the required amount of water into the inner tank through the sixth pipe. After replenishing an appropriate amount, the operator stops the input and starts the heating rod. The heating rod heats the water in the inner tank. Once the water reaches the specified temperature, the operator opens the valve and starts the pump. The water in the inner tank is then transferred to one end of the second chamber through the third pipe. The water flows back and forth within the second chamber via a baffle installed there, thus evenly heating the surface of the second pipe. When the water flows to the other end of the second chamber, it is drawn in by the fourth pipe and transferred to the pump. The pump then returns the water to the inner tank through the fifth pipe for heating and recycling. Finally, the operator turns on the steam-generating device. The device delivers the steam to the second pipe through the first pipe. The second pipe heats and insulates the steam to prevent condensation due to external factors. The steam then enters the interface through the second pipe and is finally transferred to the interior of the tower for use.

[0007] Preferably, the other end of the second pipe is connected to one side of a second flange, and the other side of the second flange is connected to the first pipe. The arrangement of the first pipe allows steam-generating equipment to transmit steam through this pipe to the interior of the second pipe, providing a transport channel.

[0008] Preferably, a partition is fixed to the outer surface of the second cavity. The installation of the partition allows a channel for back-and-forth flow to be formed inside the second cavity, so that the water in the inner tank can be evenly heated on the surface of the second pipe after it is transferred into the second cavity.

[0009] Preferably, a sixth pipe is connected to the outer top of the inner tank. The installation of the sixth pipe allows the water to be used in this invention to be transported to the interior of the inner tank through this pipe, providing a replenishment channel.

[0010] Preferably, a heating rod is fixed to the bottom of the inner tank. By installing the heating rod, the water inside the inner tank can be heated, achieving the desired heating effect.

[0011] Preferably, a valve is fixed to the bottom of the outer side of the inner tank, one end of which is connected to a third pipe, and one end of the third pipe is located inside the second cavity. Through the cooperation of the valve and the third pipe, water in the inner tank can be transferred to the interior of the second cavity, achieving the effects of opening and closing the flow.

[0012] Preferably, a fifth pipe is connected to the top of the other side of the inner tank. One end of the fifth pipe is connected to the output end of the pump body, and the output end of the pump body is connected to a fourth pipe, with one end of the fourth pipe located inside the other end of the second cavity. Through the cooperation of the fourth pipe, the pump body, and the fifth pipe, water that has entered the second cavity and heated the surface of the second pipe can be pumped back into the inner tank, achieving a recycling effect.

[0013] Preferably, a lifting frame is connected to the outer bottom surface of the outer casing, and a base is connected to the bottom end of the lifting frame. The installation of the base allows the present invention to be placed stably off the ground for use.

[0014] Preferably, the lifting frame has an internal shaft with a first support rod and a second support rod crosswise installed at both ends, and a hydraulic cylinder is connected in the middle of the shaft. By setting up the lifting frame, the outer casing can be raised and lowered based on the surface of the base, achieving the effect of adapting to the installation position of the interface and the first pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the second pipe for transmitting steam is connected to the interface of the tower body and the first pipe for outputting steam by means of a flange. It can be installed by a lifting frame according to the installation height. Multiple baffles are installed on the surface of the second pipe. After the heated water enters its surface, it can be guided by the baffles to pass evenly over the surface of the second pipe and heat its interior evenly, thus avoiding the condensation of steam into water droplets and improving the utilization efficiency of steam.

The pump body 14 then transports the water back to the inner tank 12 through the fifth pipe 13 for heating and recycling. Finally, the operator turns on the steam generating device, which transports the steam to the second pipe 4 through the first pipe 9. The second pipe 4 heats and insulates the steam to prevent it from condensing into water droplets due to external factors.
