Mobile chemical production device and method for producing water reducer using the device

Abstract

The invention provides a mobile type chemical engineering production device and a method for producing a water reducing agent by applying the device, relates to the field of chemical engineering production, and in particular relates to a mobile production device for chemical engineering production. Production equipment is concentrated in a container, so that the product producing capability is realized; the production equipment is transported to all demand places to implement water reducing agent mixing or mother liquid synthesis production, so that the production efficiency is greatly improved, and waste of repeated land acquisition for factory construction is reduced; meanwhile, the transportation cost is greatly lowered; by the method for producing the water reducing agent provided by the invention, the device can work under an atmospheric temperature condition for production of a fixed production line, and the effect that a mobile type production line method replaces the solid production line for producing the products is achieved.

technical field [0001] The invention relates to the field of chemical production, in particular to a mobile chemical production device and its production. Background technique [0002] The construction of large-scale and important projects in my country is inseparable from polycarboxylate (water reducing agent). Since the production of polycarboxylate in my country in 2009, many large-scale production lines have been built in the eastern and central regions, all of which are facing overproduction, market extension and cost. In addition, many units in the western region are repeatedly expropriating land to build factories, but this product is needed for construction in the west and foreign aid projects. In order to save national land resources, save investment in land acquisition and factory construction, and reduce logistics costs, an effective solution must be found. solution.

[0002] The construction of large-scale and important projects in my country is inseparable from polycarboxylate (water reducing agent). Since the production of polycarboxylate in my country in 2009, many large-scale production lines have been built in the eastern and central regions, all of which are facing overproduction, market extension and cost. In addition, many units in the western region are repeatedly expropriating land to build factories, but this product is needed for construction in the west and foreign aid projects. In order to save national land resources, save investment in land acquisition and factory construction, and reduce logistics costs, an effective solution must be found. Solution

[0003] In the production process of many existing polycarboxylates, first of all, a certain amount of raw materials need to be added to the reactor. When the temperature rises to about 40°C-45°C, the solid raw materials are already smooth, and other substances are added for chemical reactions. At present, the manufacturer polycarboxylate The heating method of acid production, one is steam heating, which is not directly added to the reactor, but adopts external circulation heating, which is gradually eliminated due to the problems of environmental protection and high energy consumption; the second is electric heating, most of which use stainless steel water tanks, and the manufacturing cost High, especially slow heating speed, low efficiency, high energy consumption, poor economy

[0004] In addition, many companies use the method of adding cold water first, and then putting the solid raw materials into the reaction kettle, using steam, hot water, hot oil, etc., through the method of heat transfer through the external circulation, so that the temperature of the cold water in the reaction kettle will rise, and the solid raw materials will be put into the reactor. It reaches the melting state, and then enters the chemical reaction in the stirring process. This process takes a long time, especially in winter when the water temperature is low and the heat conduction efficiency is low. It often takes several hours to reach the temperature of the chemical material, which seriously affects the production efficiency. Synthesis It takes more than 8 hours to produce a pot of mother liquor
