Description

Technical Field

[0001] The utility model belongs to the technical field of experimental ventilation waste gas purification equipment, and specifically relates to a condensation water backflow prevention structure for an experimental ventilation purification system. Background Art

[0002] Due to the use of various chemical substances in the laboratory, the air in the laboratory is polluted. Some substances not only have a bad smell, but also endanger human health. Therefore, a ventilation and purification system is usually set up in the laboratory to ventilate the laboratory and purify the exhaust gas.

[0003] At present, the ventilation purification system mostly uses activated carbon adsorption and spray tower equipment to purify the waste gas. The activated carbon box is a clean device that absorbs waste gas and harmful gases. It plays a key role in cleaning harmful gases generated in the laboratory and reducing pollution. However, it will become ineffective once it absorbs too much water. Since the pipes connecting the activated carbon box and the spray tower equipment are mostly made of PP material, when the waste gas generated in the laboratory passes through the spray tower during ventilation, it is easy to generate reflux, causing the water vapor in the spray tower to be brought into the activated carbon box, reducing the service life of the activated carbon box and affecting the waste gas purification effect. Utility Model Content

[0004] The utility model aims to solve the above problems and provides a condensation water backflow prevention structure for an experimental ventilation purification system.

[0005] The utility model is realized through the following technical scheme: a condensate backflow prevention structure for an experimental ventilation purification system, comprising an activated carbon box and a spray tower, wherein the activated carbon and the spray tower are connected via an exhaust duct one, and is characterized in that the exhaust duct one comprises an air duct one connected to the activated carbon box, the rear end of the air duct one is connected to an anti-backflow pipe, the rear end of the anti-backflow pipe is connected to an air duct two, the outlet of the air duct two is connected to the spray tower, the anti-backflow pipe is of an inclined design of "high in front and low in back", and a drain port is provided at the bottom of the exhaust duct one.

[0006] Furthermore, anti-corrosion sealing rings are provided at the connection points between the anti-backflow pipe and the air duct one and the air duct two.

[0007] Furthermore, the anti-backflow pipe is made of corrosion-resistant stainless steel.

[0008] The beneficial effect of the utility model is that the utility model arranges an anti-corrosion stainless steel backflow prevention pipe on the exhaust pipe, so that when the water vapor from the spray tower is brought into the backflow, condensation occurs in the backflow prevention pipe, and the condensed water droplets slide along the inclination to the waterproof port and are discharged through the drain port.

[0009] The utility model can timely prevent the water vapor in the spray tower from flowing back to the activated carbon box, effectively prolong the service life of the activated carbon box, improve the exhaust gas purification effect, and reduce environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model.

[0011] Figure 2 for Figure 1 Schematic diagram of the enlarged structure at point A in the middle.

[0012] In the attached drawings, 1 is an activated carbon box, 2 is an exhaust duct one, 201 is an air duct one, 202 is an anti-backflow duct, 203 is an air duct two, 3 is a spray tower, 4 is a drain port, and 5 is an exhaust duct two. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.

[0014] like Figure 1 to Figure 2 As shown, a condensate backflow prevention structure for an experimental ventilation purification system comprises an activated carbon box 1 and a spray tower 3, wherein the activated carbon and the spray tower 3 are connected via an exhaust duct 2, wherein the exhaust duct 2 comprises an air duct 201 connected to the activated carbon box 1, wherein the rear end of the air duct 201 is connected to an anti-backflow duct 202, wherein the rear end of the anti-backflow duct 202 is connected to an air duct 203, wherein the outlet of the air duct 203 is connected to the spray tower 3, and the anti-backflow duct 202 is designed to be "high in front and low in back" in an inclined manner, wherein a drain port 4 is provided at the bottom of the exhaust duct 2, i.e., the drain port 4 is provided at the lowest point of the bottom of the exhaust duct 2, and the backflow water is discharged through the drain port 4.

[0015] In order to ensure the tightness of the connection, anti-corrosion sealing rings are provided at the connection points between the anti-backflow pipe 202 and the air duct 1 201 and the air duct 2 203.

[0016] In order to condense the water vapor when it refluxes, the anti-reflux pipe 202 is made of anti-corrosion stainless steel.

[0017] During use, the exhaust gas enters the exhaust pipe 2 after passing through the activated carbon box 1, and then enters the spray tower 3 for spray purification. The water vapor generated by the spraying may be brought into the exhaust pipe 2. At this time, the anti-backflow pipe 202 of the exhaust pipe 2 is inclined, has a certain slope with the ground, and is made of anti-corrosion stainless steel. When the water vapor passes through this structure, the water vapor will condense on the inner wall of the anti-backflow pipe 202, and the condensed water droplets will slide down along their own slope to the drain port 4, and the drain valve will be opened to discharge them, so that the water vapor will no longer enter the activated carbon box 1.

[0018] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art.
