Detailed description of the invention
below in conjunction with drawings and Examples, the invention will be further described:
a kind of sack cleaner being applicable to psychro-environment as shown in Figure 1, 2, sack cleaner comprises blast pipe 1, deduster body 2, ash bucket 3 and the ash discharging system with air inlet, the discharge pipe 4 with air outlet and controls the valve module of sack cleaner all parts, blast pipe 1, deduster body 2 and discharge pipe 4 phase connect successively, and ash bucket 3 is arranged on deduster body 2 bottom.
in the present embodiment: sack cleaner also comprises and can carry out the pre-heating system of preheating, the deashing injection system that can prevent high-temperature flue gas local condensation in deduster body 2, ash bucket heating and heat-insulation system, deduster insulation of body system and tracing thermal-insulating system to deduster body 2.Below specifically each system is described in detail:
as shown in Figure 3: pre-heating system comprises blower fan 5, heater 6, blower fan 5, heater 6 by being connected with deduster body 2 after placed in series, and the entrance of pipeline, outlet, the entrance of blast pipe 1, discharge pipe 4, outlet are provided with stop valve 7.
when sack cleaner cold boot time, high-temperature flue gas enters the deduster body 2 of cold conditions, can because of generation dew condensation phenomenon of catching a cold, cause dust to harden, stick with paste bag and extra erosion problem, so, before high-temperature flue gas enters deduster body 2, need deduster body 2 to be preheating to suitable temperature, avoid high-temperature flue gas quenching to condense as far as possible.The blast pipe 1 of closedown deduster body 2, the stop valve 7(of discharge pipe 4 entrance open when normally running), the stop valve 7(of unlatching pre-heating system entrance, outlet closes when normally running), open pre-heating system blower fan, last heater, make heat at deduster body 2 internal circulation by blower fan, progressively improve deduster body 2 internal temperature, control pre-heating system by heating-up temperature preset value and the temperature sensor be located on casing.
as shown in Figure 5: deashing injection system comprises compression gas tank 8 for storing deashing gas, import is connected to electric heater 9 in the outlet of compression gas tank 8, inlet parallel is connected to several gas bags combination 10 in the outlet of electric heater 9, be connected to the exit of gas bag combination 10 diffuse pipeline 11, diffuse on pipeline 11 and be provided with the control valves such as stop valve 120, choke valve 121, automatic valve 122.Gas bag combination 10 comprises several point gas tank 100, stop valve 130 and choke valves 131 of being connected in series.Like this, controlled the temperature of blowing gas by electric heater 9, multiple control valve closes the gas of 10 inside for heating displacement gas package, makes it reach the temperature of setting gradually.
in order to ensure that flue gas can not condense because of local quenching when deashing, cause dust to harden and stick with paste bag problem, and the corrosion of aggravation deduster body 2 internal component and box plate, so default only has just allow pulse valve blowing deashing after blowing gas reaches design temperature (0-200 DEG C, adjustable).
the concrete structure of deashing injection system also with reference to the CN 102363088A " deashing gas heating system for preventing dewing in bag filtration " of applicant's application, just no longer can repeat at this.
