Description

Technical Field

[0001] The utility model relates to the technical field of tail gas recovery, in particular to a device for recovering tail gas from ammonia production. Background Art

[0002] Ammonia has many uses in industry and laboratories, such as cleaning agents and decontaminants, gas absorbents, fertilizer production, metal surface treatment, preparation of other chemicals, and laboratory uses. It has the properties of decontamination, deodorization and disinfection. It is often used to clean surfaces such as glass and stainless steel. It can also be used to clean places such as kitchens and bathrooms.

[0003] After searching, a Chinese patent discloses a tail gas treatment device for ammonia production (authorization announcement number CN217939682U) including a water storage tank, a cyclone is fixedly connected to the top of the water storage tank, a gas-liquid separator is fixedly connected to the top of the cyclone through a pipeline, the bottom of the gas-liquid separator is fixedly connected to the water storage tank through a pipeline, a water pump is arranged on one side of the water storage tank, and the output end of the water pump is fixedly connected to the cyclone through a pipeline. Although the above patent technology can prevent the exhaust air from mixing with more water vapor and causing nearby equipment to rust and age after being damp by setting a gas-liquid separator, it has a simple structure, low cost and is easy to produce. By setting a cyclone, when the inner wall of the cyclone is corroded by ammonia water and damaged after a period of use, the vortex body, the straight cylinder body and the cone cylinder can be replaced or maintained separately according to the degree of damage, and the cyclone does not need to be replaced as a whole, thereby reducing the cost of maintenance;

[0004] However, in the actual application of this patented technology, the above-mentioned ammonia production exhaust gas treatment device cannot clean the filter when in use. On the one hand, over time, dust, particulate matter and other pollutants will accumulate on the surface of the filter, causing the pores of the filter to be blocked, thereby reducing the speed and efficiency of gas passage. This will make it impossible for the exhaust gas treatment device to effectively remove harmful substances, thereby affecting the treatment effect of the exhaust gas. On the other hand, when the filter is contaminated and blocked, the exhaust gas treatment device needs to apply greater pressure to push the exhaust gas through the filter, which will increase the energy consumption of the system.
