Description

A kind of pressure spray drying tower with quick wind cooling temperature lowering function
Technical field
This utility model belongs to pressure spray drying tower technical field, particularly to a kind of pressure spray drying tower with quick wind cooling temperature lowering function.
Background technology
The esters of acrylic acid functional polymer auxiliary agents such as ACR, AIM, MBS and other thermoresponsive polymer have decomposes and flammability, series of problems and the risk such as once heating temperature is too high, the long variable color of will decomposing of heated time, rotten, overheated burning.Now being spray-dried esters of acrylic acid functional polymer emulsion with pressure spray drying tower, dry run uses the hot-air of 180-250 DEG C to be dried material, and equipment does not has quick temperature-reducing function device, it is impossible to carry out fast cooling disposal.In production process, once hot blast temperature control system is out of control or polymer emulsion spraying control system is malfunctioning, polymer is easily caused to decompose variable color, the series of problems such as wall, overheated burning rotten, viscous in spray drying tower if temperature over-range, will result in polymeric material temperature too high, cause product to glue wall, decompose variable color, the series of problems such as rotten.
Summary of the invention
For solving above-mentioned technical problem present in prior art, this utility model provides a kind of pressure spray drying tower with quick wind cooling temperature lowering function.
nullThe purpose of this utility model is achieved through the following technical solutions: a kind of pressure spray drying tower with quick wind cooling temperature lowering function,Including dry tower body、Hot-air preparation system、LS system、Exhaust treatment system、DCS or PLC control system and quick Wind cooling temperature reducing device,Described dry tower body includes air compartment and hothouse,Described air compartment is connected with hot-air system by pipeline,Connect on described pipeline and have quick Wind cooling temperature reducing device,Thermal resistance installed by described hothouse,Temperature in hothouse is measured by described thermal resistance in real time,If temperature is higher than set temperature value,The most described DCS or PLC control system control the hot air duct stop valve of hot-air system and close,Described DCS or PLC control system control the cold air duct stop valve of described quick Wind cooling temperature reducing device and open,Cold wind is sent into described hothouse.
Preferably, described quick Wind cooling temperature reducing device includes air filter and automatic control stop valve.
This utility model provides the benefit that: in this utility model when spray drying tower internal temperature exceed process stipulation need fast cooling time, enter tower hot air duct stop valve to close, cold air duct stop valve is opened, cold wind enters inside drying tower, can be with fast cooling, eliminate polymeric material temperature too high, cause product to glue wall, decompose the series of problems such as variable color, rotten, overheated burning.
Accompanying drawing explanation
Fig. 1 is the pressure spray drying tower structural representation with quick wind cooling temperature lowering function of the present utility model;
In figure: 1 air compartment, 2 spray chambers, 3 first hothouses, 4 secondary drying chambers, 5 expansion chambers, 6 gather materials room, 7 screw discharging machines, 8 spin vibration sieves, 9 feed screws, 10 cyclone separator, 11 sack cleaners, 12 air-introduced machines, 13 atomizers, 14 emulsion pumps, 15 heat exchangers, 16 air filters, 17 quick Wind cooling temperature reducing devices, 18 hot air duct stop valves, 19 cold air duct stop valves, T1 the first thermal resistance, T2 the second thermal resistance, T3 the 3rd thermal resistance.
Detailed description of the invention
In conjunction with the accompanying drawings and embodiments this utility model is described further.
A kind of pressure spray drying tower with quick wind cooling temperature lowering function, including dry tower body, hot-air preparation system, LS system, exhaust treatment system, DCS or PLC control system and quick Wind cooling temperature reducing device, described dry tower body includes air compartment and hothouse, described air compartment is connected with hot-air system by pipeline, connect on described pipeline and have quick Wind cooling temperature reducing device, thermal resistance installed by described hothouse, temperature in hothouse is measured by described thermal resistance in real time, if temperature is higher than set temperature value, the most described DCS or PLC control system control the hot air duct stop valve of hot-air system and close, described DCS or PLC control system control the cold air duct stop valve of described quick Wind cooling temperature reducing device and open, cold wind is sent into described hothouse.
Preferably, described quick Wind cooling temperature reducing device includes air filter and automatic control stop valve.
nullEmbodiment: a kind of pressure spray drying tower with quick wind cooling temperature lowering function,Including dry tower body、Hot-air preparation system、LS system、Exhaust treatment system、DCS or PLC control system and quick Wind cooling temperature reducing device,Described dry tower body includes air compartment 1、Spray chamber 2、First hothouse 3、Secondary drying chamber 4、Expansion chamber 5、Gather materials room 6,Described air compartment 1 is connected with air-supply arrangement,Described air-supply arrangement includes heat exchanger 15、Air filter 16 and the first thermal resistance T1,Described spray chamber 2 is upper cone structure,Described spray chamber 2 is provided with atomizer 13,Atomizer 13 is connected with emulsion pumps 14 by pipeline,Described secondary drying chamber 4 is provided with the second thermal resistance T2,Lower end, described secondary drying chamber 4 connects expansion chamber 5,Expansion chamber 5 is connected with the room 6 that gathers materials,The room 6 that gathers materials is connected with screw discharging machine 7,Screw discharging machine 7 is connected with spin vibration sieve,Spin vibration sieve 8 is connected with feed screw 9,Feed screw 9 is connected with cyclone separator 10 and sack cleaner 11 respectively,Described cyclone separator 10 is connected with described expansion chamber 5 by pipeline,On pipeline between described cyclone separator 10 and expansion chamber 5, the 3rd thermal resistance T3 is installed,Described cyclone separator 10 is connected with sack cleaner 11,Sack cleaner 11 is connected with air-introduced machine 12.
Air compartment 1 described in this utility model is connected with hot-air system by pipeline, connect on described pipeline and have quick Wind cooling temperature reducing device 17, the second thermal resistance T2 installs in described secondary drying chamber 4, temperature in secondary drying chamber 4 is measured by described second thermal resistance T2 in real time, if temperature is higher than set temperature value, the most described PLC control system controls the hot air duct stop valve 18 of hot-air system and closes, described DCS or PLC control system control the cold air duct stop valve 19 of described Wind cooling temperature reducing device and open, and send into cold wind to described hothouse.
So, when pressure spray drying tower is because hot blast temperature control system is out of control or polymer emulsion spraying control system is malfunctioning, in spray drying tower during temperature over-range, can the most effectively carry out wind cooling temperature lowering disposal, eliminate polymer builder high-temperature fusion and glue wall, decompose variable color, rotten, the problem of overheated burning and risk.
In this description, this utility model is described with reference to its specific embodiment.But it is clear that still various modifications may be made and conversion is without departing from spirit and scope of the present utility model.Therefore, specification and drawings is regarded in an illustrative, rather than a restrictive.
