A high-efficiency multifunctional polymer emulsion drying equipment

Abstract

The invention discloses efficient multifunctional polymer emulsion drying equipment. The efficient multifunctional polymer emulsion drying equipment comprises a pressure atomizing drying system, a pulse gas flow cooling system and a control system, wherein the pressure atomizing drying system comprises a drying tower body, a pressure atomizing device, an in-tower hot air preparation device, a powder auxiliary atomizing adding device, a tail gas cooling device, a rapid air cooling device and a fire extinguishment spraying device; and the pulse gas flow cooling system comprises a pulse gas flow cooling device and a material collection and conveying and tail gas treatment device. According to the efficient multifunctional polymer emulsion drying equipment, a plurality of problems of an atomizing and drying tower that a polymer auxiliary is stuck on a wall and stuck with materials, polymer powder has a high temperature and is caked to block a cloth bag dust remover, a dried polymer has a high temperature and is easy to cake, the cooling treatment is slow after the temperature in the drying tower is too high, no excessive temprature or no fire disaster risk prevention and treatment capability is available and the like are solved, so that the yield is high, the safety property is good, the energy consumption is low, and work delay caused by production halts is short.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, in particular to a high-efficiency multifunctional polymer emulsion drying equipment. Background technique [0002] The production of polyacrylate functional polymer materials such as ACR, AIM, and MBS adopts the aqueous phase emulsion polymerization process, and the prepared polymer emulsion can be dried to obtain powder functional polymer additive products. At present, the dry production of polymer emulsion mainly adopts the spray drying of the pressure spray drying tower. The existing pressure spray drying tower has the problems of polymer additives sticking to the wall, polymer powder with high temperature sticking and blocking the bag filter, and polymerization after drying. There are many defects such as high product temperature, easy agglomeration, slow cooling and disposal when the temperature in the drying tower exceeds the temperature, no over-temperature or fire risk preventio...

Problems solved by technology

At present, the dry production of polymer emulsion mainly adopts the spray drying of the pressure spray drying tower. The existing pressure spray drying tower has the problems of polymer additives sticking to the wall, polymer powder with high temperature sticking and blocking the bag filter, and polymerization after drying. There are many defects such as high product temperature, easy agglomeration, slow cooling and disposal when the temperature in the drying tower exceeds the temperature, no over-temperature or fire risk prevention and disposal ability, etc., resulting in high operating risk, poor adaptability, low production capacity, high energy consumption, and so on. Long downtime
