Problems solved by technology
[0004] Detrimental effect on equipment life
[0005] 2. Since solid industrial naphthalene is put into the sulfonation reactor, it is easy to smash the reactor
[0007] 3. During the whole process of melting naphthalene and sulfonation reaction, the steam consumption is very large, causing
[0008] waste of energy
[0009] 4. The production cycle is relatively long, and the labor intensity of workers is relatively high, which is not convenient for workers to live.

The present invention provides a high-effective water-reducing agent production equipment and its production process. Said production equipment includes existent sulfonation reactor and condensation reactor, and contains heat conductive oil furnace, heat-conducting oil pipeline, naphthalene melting tank and its submerged oil pump, liquor metering pump and liquid naphthalene conveying pipeline, and its production process includes the following steps: using the heat-conducting oil of heat conductive oil furnace to melt solid industrial naphthalene in naphthalene-melting tank, pumping the liquidnaphthalene into metering tank, then feeding the liquid naphthalene into condensation reactor, making condensation and neutralization reaction to obtain the liquid naphthalene series high-effective water-reducing agent.
Description
technical field [0001] The invention belongs to the field of chemical product production, in particular to a high-efficiency water reducer production equipment and a production process thereof. Background technique [0002] High-efficiency water reducer is a chemical product, which is a liquid naphthalene-based high-efficiency water reducer product that uses industrial naphthalene as the main raw material and undergoes melting naphthalene, sulfonation reaction, hydrolysis reaction, condensation reaction, and neutralization reaction. In the existing high-efficiency water reducer production technology, steam is used as the main heat source. The process is as follows: firstly, solid industrial naphthalene is put into the sulfonation reactor, and a pressure of 0.6MPa is introduced into the jacket of the sulfonation reactor. After 3 hours, the solid naphthalene melted into liquid naphthalene, and when the liquid naphthalene reached a certain temperature, 98% concentrated sulfuric...
