Embodiment 1

[0026] figure 1 Schematically shows imidazolidine drying systems according to two embodiments of the present invention.

[0027] Such as figure 1 As shown, the imidazolidine drying system of the present invention includes a dryer host 10 . The host 10 of the dryer is an "n"-shaped drying passage, the input end 11 of the main dryer 10 is located at the bottom of one side of the "n"-shaped drying passage, and the output end 12 is located at the other side of the "n"-shaped drying passage; A material inlet 111 is provided on the end side wall; a steam heater 20 is connected to the opposite side of the material inlet 111; a spiral stirring system 101 is provided between the material inlet 111 and the steam heater 20 at the bottom end of the input end 11, The spiral stirring system 101 includes a motor 1011 located in the main body of the dryer 10 and a spiral turntable 1012 connected to the output shaft of the motor, the output shaft of the motor is vertically arranged; the outp...

Embodiment 2

[0031] The structure of this embodiment of the present invention is basically the same as that of claim 1, the difference being that a flame sensor is installed in the dryer host 10, the flame sensor is connected to the control system, and the valve 601 is connected to the control system and controlled by the control system.

[0032] At this time, the flame sensor can automatically sense the flame and fire light, and send the signal to the control system. After the control system receives the flame signal, the automatic control valve 601 is opened, and water vapor is passed in to extinguish the fire. The phenomenon of untimely firefighting caused by the negligence of the staff guards reduces the labor intensity of the staff.

[0033] In this embodiment, the output temperature of the steam heater 20 is 190°C; the temperature of the imidazolidine output from the output port 12 of the dryer host 10 is 65°C.

[0034] In summary, the imidazolidine drying system provided by the pres...

Abstract

The invention provides an imidazolidine drying system comprising a dryer mainframe. A feed end of the dryer mainframe is connected with a steam heater, and a discharge end of the dryer mainframe is connected with a material inlet of a rotary separator. A gas outlet of the rotary separator is connected with a dusty gas inlet of a dust collector; a purified gas outlet of the dust collector is connected with an induced draft fan; the dryer mainframe is further connected with a firefighting water steam passage, and a valve is arranged at the joint of the water steam passage and the dryer mainframe; a spiral stirring system is further arranged at the feed end of the dryer mainframe. The imidazolidine drying system has the advantages that structural layout is reasonable, and operation is facilitated; meanwhile, due to the arrangement of the firefighting water steam passage, after materials in the dryer mainframe are burnt, water steam can be fed timely for fire fighting, and fire hazards can be eradicated effectively.

Description

technical field [0001] The invention relates to the field of imidazolidine production equipment, in particular to an imidazolidine drying system that eliminates fire hazards. Background technique [0002] The drying system is a mechanical system that uses thermal energy to reduce the moisture content of materials, and is used to dry objects. The drying system evaporates and escapes the moisture (generally water or other volatile liquid components) in the material by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. [0003] The drying system usually operates under the conditions of high temperature, high pressure and high dust, and the machine is prone to fire and even explosion accidents. [0004] The two factors for the drying system to catch fire are: 1. Very high temperature; 2. Combustible substances The drying system works under the conditions of high temperature and...
