Description

Filter with efficient circulation function Technical Field The utility model relates to the technical field of hydrogen peroxide production, in particular to a filter with an efficient circulation function. Background In the complex flow of hydrogen peroxide production, the filter plays an irreplaceable important role, like a guard on a production line, can accurately and efficiently filter various impurities mixed in working solution, builds a firm foundation for continuous and stable operation of production, is a key ring for guaranteeing the product quality to reach high standards, however, in the current actual production process, the replacement of a filter element and the treatment link of a new filter element expose a plurality of difficult problems which are difficult to solve. The traditional filter element replacing mode has obvious defects, when the filter element is cut out, a large amount of working solution is always remained in the scrapped filter element, the residual working solution not only causes potential pollution to the environment and increases the environmental protection pressure of enterprises, but also can cause unnecessary rising of the production cost, because the loss of the working solution means waste of resources and increase of economic cost, in addition, when the filter element is repeatedly used for realizing the aim of saving energy and reducing consumption, new dilemma is faced, when the filter element is subjected to ultrasonic cleaning, the excessive residual working solution in the filter element greatly hinders the smooth development of cleaning work, the cleaning effect is reduced, the loss of the working solution is further increased, meanwhile, a large amount of working solution is contained in sewage generated by cleaning, the difficulty and cost of sewage treatment are undoubtedly increased, more importantly, after the filter element is replaced, the glue contained in the new filter element can have serious negative influence on the subsequent production flow, the original composition of the working solution can be interfered by the impurities in the new filter element, further influence on the reaction in the hydrogen peroxide production process, the production efficiency is greatly reduced, the production quality is also seriously influenced, the market-friendly quality of the product is difficult to reach the expected market standard of the system is greatly influenced. Disclosure of utility model In order to solve the technical problems, the filter with the efficient circulation function is provided, the technical scheme solves the problem that the traditional filter element replacement mode provided in the background technology has obvious defects, when the filter element is cut out, a large amount of working solution is always remained in the scrapped filter element, the residual working solution can cause potential pollution to the environment, the environmental protection pressure of enterprises is increased, the unnecessary rising of production cost can also be caused, the loss of the working solution means the waste of resources and the increase of economic cost, in addition, when the filter element is repeatedly used for realizing the aims of saving energy and reducing consumption, the novel dilemma is faced, when the filter element is subjected to ultrasonic cleaning, the excessive residual working solution in the interior greatly hinders the smooth development of cleaning work, not only reduces the cleaning effect, but also further aggravates the loss of the working solution, meanwhile, a large amount of working solution is contained in sewage generated by cleaning, the difficulty and cost of sewage treatment are definitely increased, more importantly, the glue contained in the novel filter element can not be effectively treated in time, the case of serious subsequent production flow is wasted, the novel filter element can have serious influence on the subsequent production flow, the quality of the hydrogen peroxide can be greatly influenced, the expected negative effect of the product is greatly influenced in the market, and the production system is greatly influenced by the expected negative effect of the product quality of the product is greatly, and the product quality of the product is greatly influenced by the expected fluctuation, and the problem is greatly influenced by the market.
