Description

Technical Field

[0001] The utility model relates to the technical field of steam collection equipment in a coking production area, in particular to a steam tail gas cooling and collection device. Background Art

[0002] my country is a major coking country. In 2016, the world's coking capacity was 650 million tons, of which my country's was 450 million tons, accounting for nearly 70%. As environmental protection becomes increasingly severe, how to solve the problem of zero pollution in waste gas purification has become an indispensable process link in the coking industry.

[0003] Steam will generate a lot of exhaust gas during use. If it is discharged directly, it will not only cause a lot of energy waste, but also form a lot of water vapor when the steam exhaust is discharged, affecting the surrounding environment. The existing treatment method is to pass the steam exhaust through a heat exchanger to generate hot water or hot air for recycling; however, the above treatment method has the disadvantage of incomplete heat recovery and utilization, and steam or condensed water will be discharged from the pipeline.

[0004] The publication number is CN215114064U; the name is: A steam tail gas recovery and utilization device, which specifically discloses: a steam tail gas pipe, an insulated water tank and a circulating cooling pipe, the steam tail gas pipe is connected to the water inlet of the insulated water tank, the water outlet of the insulated water tank is connected to one end of the circulating cooling pipe, the other end of the circulating cooling pipe is connected to the inside of the steam tail gas pipe, and a circulating pump is arranged on the circulating cooling pipe. The steam tail gas recovery and utilization device provided in this application can completely collect the discharged steam tail gas in the insulated water tank, avoiding the steam tail gas from being directly discharged into the atmosphere, solving the problem of incomplete steam tail gas recovery and utilization, reducing the impact on the surrounding environment, and the water in the insulated water tank can be reused for a second time, thereby improving the utilization rate of water.

[0005] The above device has a complex structural design, is inconvenient to maintain and operate, and results in a short service life. Utility Model Content

[0006] The utility model aims to provide a steam exhaust gas cooling and collecting device which has a reasonable and simple structural design, is convenient to use and install, is easy to operate, has a low processing and manufacturing cost, is safe and reliable to use, and is energy-saving and environmentally friendly.

[0007] The utility model discloses a steam tail gas cooling and collecting device, comprising a sleeve, a cooling water outlet pipe is fixedly installed on the surface of the sleeve, a cooling water inlet pipe is fixedly installed on the bottom surface of the sleeve; sealing plates are fixedly installed on the two end surfaces of the sleeve, and a transmission pipeline is installed through the two sealing plates.

[0008] The set casing and sealing plate can form a closed space, and water can be injected into the closed space through the cooling water inlet pipe and the cooling water outlet pipe, so as to cool the steam entering the transmission pipeline; one end of the set transmission pipeline can be connected to the steam exhaust pipe to collect and cool the steam exhaust gas, and the collected steam exhaust gas is cooled and turned into cooling water, which can flow out through the transmission pipeline for recycling and enter the circulating water system, so as to completely eliminate the safety risks caused by the steam exhaust gas dripping to the production site and the freezing of production equipment; at the same time, the steam condensate is collected and supplemented to the circulating water system, so as to reduce the water consumption in the production area, save energy and protect the environment, and has strong practicality.

[0009] The side wall surfaces of the blocking plates arranged on both sides are provided with reserved holes.

[0010] The reserved holes can be used to install the transmission pipeline, and at the same time support and fix the transmission pipeline, making the installation safer and more stable.

[0011] The transmission pipeline includes a first transverse pipe, a second transverse pipe, a third transverse pipe, a first connecting elbow and a second connecting elbow. The third transverse pipe penetrates the sealing plate and enters the interior of the casing through a reserved hole. The end of the third transverse pipe is fixedly connected to the first transverse pipe through the second connecting elbow. The end of the first transverse pipe is fixedly connected to the first connecting elbow. The end of the first connecting elbow is fixedly connected to the second transverse pipe. The second transverse pipe penetrates the sealing plate and extends to the outside of the sealing plate through the reserved hole.

[0012] The first transverse tube, the second transverse tube and the third transverse tube are arranged parallel to each other.

[0013] Setting the transmission pipeline as the first transverse pipe, the second transverse pipe, and the third transverse pipe can increase the flow path of the collected steam exhaust gas, which is more conducive to the cooling of the steam exhaust gas and ensures the cooling effect.

[0014] The second transverse tube and the third transverse tube are arranged with the same length; the length of the second transverse tube and the third transverse tube is greater than the length of the first transverse tube.

[0015] The curvature of the first connecting elbow is smaller than that of the second connecting elbow.

[0016] The first connecting elbow and the second connecting elbow can be used to connect the first transverse pipe, the second transverse pipe and the third transverse pipe, so as to ensure that the flow path of the collected steam exhaust gas is smoother and enhance the fluidity of the steam exhaust gas.
