[0015] Figure 1 It is the structure diagram of a compressed air purification device of the utility model. DETAILED DESCRIPTION

[0016] The utility model will be described further below with the accompanying drawings and relevant knowledge, and it is obviously that the application only is a part of the embodiment of the utility model, but not all the embodiment.

[0017] Referring to Figure 1 The utility model discloses a compressed air purification device, including air inlet end pipeline 1, slow -release pipeline 2, confluence pipe 3 and purification pipeline 4 that set gradually, air inlet end pipeline 1 with slow -release pipeline 2 between set gradually have gas -water separator 5, oil mist separator 6, fine dust collector 7. Through main pipeline air inlet end is provided with gas -water separator, oil mist separator, fine dust collector, enters slow -release pipeline after three -stage filter, and slow -release pipeline is connected to purification pipeline 4, finally gathers to BA grade gas holder for downstream use, can provide the compressed air after purification. In the utility model, slow -release pipeline is convenient for the slow passage of gas, and subsequent filtration is facilitated, and further gas is shunted by setting the confluence pipe, better purification is realized, and more specifically, the use of the confluence pipe not only effectively reduces the negative pressure loss, increases the single-channel negative pressure, and effectively improves the pumping negative pressure.

[0018] In the utility model, the diameter of slow -release pipeline 2 is 2 times of the diameter of air inlet end pipeline 1, and further preferably, the diameter of slow -release pipeline is 2 inches, and the diameter of air inlet end pipeline is 1 inch, so that the pressure at the air inlet end is greater than the pressure of slow -release pipeline, the air inlet is facilitated into the purification device, and subsequent purification of the gas is facilitated, and the processing flow can be realized: 10bar pressure, maximum flow 3000SLPM.

[0019] In the utility model, the confluence pipe 3 includes the first confluence pipe and the second confluence pipe arranged side by side, so that the compressed air can enter the slow -release pipeline after three -stage filtration, and then be shunted by the confluence pipe.

[0020] Furthermore, the purification pipeline 4 includes four purification branches. The first confluence pipe is connected to two purification branches, and the second confluence pipe is connected to the other two purification branches. That is to say, after passing through the confluence pipe, it branches into four purification branches, which can carry out subsequent purification more efficiently.

[0021] As a further solution of the present invention, two high-efficiency filters 8 and an ultra-high-efficiency filter 9 are sequentially installed on the purification branch, wherein the two high-efficiency filters are located between the manifold and the ultra-high-efficiency filter. It is further preferred that both the high-efficiency filter and the ultra-high-efficiency filter are equipped with differential pressure sensors. After the compressed air passes through the three-stage filtration, it enters the slow-release pipeline, which is connected to four purification branches. Each purification branch first passes through two high-efficiency filters, and then an ultra-high-efficiency filter is connected to the rear end of the high-efficiency filter. Each filter is equipped with a differential pressure sensor to monitor the change from initial pressure to final resistance pressure. When the final resistance pressure is reached, an alarm message is output to remind the replacement of the filter element.

[0022] To sum up, the air inlet end pipeline of the utility model is a 1-inch compression fitting, which is connected to the gas-water separator, oil mist separator, fine dust collector, and connected to a 1-inch to 2-inch VCR adapter. The adapter is connected to a 2-inch slow-release pipeline, and the slow-release pipeline is connected to the manifold. The three 1-inch connectors of the manifold are connected to four purification branches. A pressure difference is formed between the air inlet end and the air outlet end to facilitate the passage of gas. Preferably, the diameter of the slow-release pipeline is twice the diameter of the air inlet end, and the pipeline diameter of the purification branch is consistent with the diameter of the air inlet end pipeline. The above-mentioned pipeline can realize convenient entry and passage of gas and can achieve better subsequent filtration effect, mainly through the manifold and then through the purification branch to achieve better filtration. That is to say, by setting four purification branches, it is convenient to achieve better purification effect. Each purification branch first passes through two high-efficiency filters, and the rear end of the high filter is connected to an ultra-high-efficiency filter, and finally reaches the BA-level gas storage tank. Each filter is equipped with a differential pressure sensor to monitor the change from initial pressure to final resistance pressure. When the final resistance pressure is reached, an alarm message is output to remind you to replace the filter element.
