Description
One, technical field
The utility model relates to a kind of central air-conditioning air channel cleaning device, and it is mainly used in the cleaning of central air-conditioning air channel, and the safety of pipe interior laying dust is collected and removed.
Two, background technology
The air channel cleaning that present domestic air-conditioning cleans enterprise's employing is varied, and existing early stage chemical cleaning method and artificial cleaning method also have the more mechanical cleaning method of present employing.China's central air conditioner system air channel laying dust type mostly is respirable dust, and owing to fail for many years in time to clean, general laying dust is thicker.Present existing central air-conditioning air channel cleaning technique all is air motion modes of taking the unidirectional suction of dust catcher.
At present popular at home and abroad is " mechanical ablution is removed in the source " (see figure 1).Its method feature is: adopt blow device 2 to work in and be cleaned 3 inside, air channel, blow device 2 uses modes such as vibrating, stir, whisk off, and the inner-walls of duct laying dust is come off, and is suspended in the pipe interior space; Dust catcher 6 produces air inducing, by flexible pipe 5 with laying dust from the pipeline sucking-off, dust catcher 6 is collected laying dust, air is discharged, thereby reach the removal laying dust, purifies the purpose in air channel.Its device characteristic is: use air bag 1 shutoff to be cleaned the two ends in air channel 3, connect the birdsmouth 4 and dust catcher 6 that is cleaned under the air channel 3 with washing hose 5, form the system of a non-complete closed.The motion of its air-flow relies on the simple suction of dust catcher to realize, after dust-contained airflow enters dust catcher 6 and is cleaned, is directly discharged, and the system pressure balance is entered by new wind and is cleaned the air channel and realizes.Its drawback is: on the one hand, because gas-flow resistance is slow than ambassador's circulation rate of bringing about the desired sensation, rely on the cleaning process power performance of simple drawing-in type of dust catcher not good, air motion speed is slower, and the laying dust collection efficiency is low; On the other hand, because system is not a complete closed, all there is mass exchange in system with outside air all the time, thereby has increased the possibility of pollution sources diffusions, can not stop secondary pollution fully.
Three, the utility model content
The technical problems to be solved in the utility model is in the cleaning process of above-mentioned central air-conditioning air channel, a kind of employing air-flow closed-circulating dust collection manner air duct cleaning method is provided, overcome the shortcoming that " source removal mechanical cleaning method " utilizes the simple suction airstream motion mode of dust catcher, improve the power performance of air motion, improve the control of dust collection efficiency, effectively avoid secondary pollution; A kind of central air-conditioning air channel cleaning device that adopts closed-circulating dust collection manner based on this method formation.
Technical thought of the present utility model is, as shown in Figure 3,: the dust-contained airflow endless form is the closed cycle mode, washing hose 5, high-power blower 8, high-efficiency dust collecting clarifier 9 and be cleaned the system that air channel 3 has constituted a complete closed in the cleaning process of central air-conditioning air channel, provide power by high-power blower 8, make dust-contained airflow flow, enter inner continuation the in air channel again after dust-contained airflow is filtered through high-efficiency dust collecting clarifier 9 and circulate in internal system.
The device that the utility model is used, comprise air bag 1, be cleaned air channel 3 and blow device 2, as shown in Figure 2, it is characterized in that: the control of dust part of this device connects high-efficiency dust collecting clarifier 9 by flexible pipe 5 and high-power blower 8 is formed, thereby replaced the dust catcher 6 in " mechanical ablution is removed in the source " device, again with flexible pipe 5 with this control of dust part be cleaned air channel 3 and be connected, specifically be connected to: the air intake port 7 of high-efficiency dust collecting clarifier 9 is connected with left side birdsmouth 4 under being cleaned air channel 3 with flexible pipe 5, with flexible pipe 5 the air-out port 12 of high-power blower 8 is connected with right side birdsmouth 13 under being cleaned air channel 3 simultaneously, constitutes the system of a complete closed thus.
Main technical schemes of the present utility model is: the laying dust that the air channel inwall adheres to is hit in blow device 2 generation effects down, utilize high-power blower 8 to produce high speed air inducing simultaneously in the internal system of this complete closed, make laying dust be suspended in the pipe interior space, and formation high concentration dust-contained airflow, dust-contained airflow circulates in internal system, realize separating of laying dust and air-flow after filtering through efficient laying dust clarifier 9, thereby with the collection and the removal of laying dust safety.
The beneficial effects of the utility model are: (1) whole process is carried out in the system of sealing, does not have air-flow to leak, and avoids the diffusion of the pollutant that causes because of air current flow, has effectively stopped secondary pollution.(2) air-flow after the filtration continues to have made full use of the kinetic energy of this part air-flow at the internal system shuttling movement, the system dynamic better performances, and cleaning speed and laying dust collection efficiency are improved.(3) utilization method and apparatus of the present utility model cleans State Grid Corporation of China's power supply dispatching center central air-conditioning ventilation shaft, cleans back airduct clean level up to 0.08g/m
2, be higher than national standard and require 1.0g/m
