Purification device for sewage and waste gases produced by regenerated lead industry

Abstract

The invention relates to the technical field of sewage and waste gas purification of regenerated lead, and discloses a purification device for sewage and waste gases produced by the regenerated lead industry. The purification device comprises an air inlet pipe and a water inlet pipe, wherein one end of the air inlet pipe is in communication with one end of a first three-way pipe; the other ends ofthe first three-way pipe are in communication with sides of the bottoms of separation tanks; a partition plate is fixedly mounted at the middle part of an inner cavity of each separation tank; a heavy metal adsorption layer is fixedly mounted at the middle part of one side of each partition plate; and the sides of the tops of the separation tanks are in communication with ends of first air guiding pipes. According to the purification device for the sewage and the waste gases produced by the regenerated lead industry, by the cooperative use of the separation tanks, the partition plates, the first three-way pipe and a second three-way pipe, a worker can implement inspection and maintenance on some equipment by closing or opening valves on pipes without stopping the purification device, thereby avoiding the problem that some of emissions are directly discharged when the purification device fails, and improving the purification effect of the purification device.

Description

technical field [0001] The invention relates to the technical field of sewage and waste gas purification of regenerated lead, in particular to a purification device for sewage and waste gas produced in the regenerated lead industry. Background technique [0002] With the continuous development of the lead industry, the consumption of lead raw materials is increasing, and its recoverable resources are becoming less and less. Therefore, the recycling and reuse of lead has naturally become the focus of the lead industry. As the main application of lead, the storage battery industry, its use The life span ranges from 5 to 15 years, and my country is a big country in the production and use of lead-acid batteries, so there is a huge space for its recycling and reuse. However, the process of lead recycling will produce a lot of waste gas and sewage, which is easy to damage the environment. Cause serious pollution, and as the country is constantly increasing the emphasis on environmen...

Problems solved by technology

[0004] The invention provides a purification device for sewage and waste gas produced in the secondary lead industry, capable of treating the waste gas regardless of maintenance, fully absorbing sulfide and nitrogen oxides in the waste gas, accelerating the process of absorbing sewage by flocculants, and having a good purification effect It solves the problem that due to the large amount of equipment required for the sewage and exhaust gas purification device, some equipment will inevitably have some failures during the working process, and need to be shut down for maintenance, but the process of regenerated lead processing is difficult to stop directly, so there are some The possibility of direct emissions, and at the same time, most of the waste gas generated during the processing of recycled lead is sulfide and nitrogen oxides. If they cannot be fully absorbed, it is easy to cause great damage to the environment. In addition, the waste gas generated during the processing of recycled lead Sewage needs to be absorbed by flocculants, but only relying on flocculants to treat sewage slowly, it is difficult to deal with a large amount of sewage in a timely manner
