Description

Technical Field

[0001] This utility model relates to the field of acid mist recovery technology, and in particular to an acid mist recovery device for washing tanks. Background Technology

[0002] In industries such as electroplating, chemical processing, and metal surface treatment, pickling tanks generate a large amount of acid mist, which not only corrodes equipment and harms workers' health, but also causes environmental pollution. Effective recycling and treatment of acid mist is necessary to reduce environmental pollution. Therefore, a pickling tank acid mist recovery device is used.

[0003] To address this, patent CN215842400U discloses an acid mist recovery device for a hot-dip galvanizing pickling tank, relating to the technical field of acid mist recovery devices. The device includes a tank body with a sealing device on its top wall for controlling the opening and closing of the tank opening. An acid mist recovery device is located on one side of the tank body, comprising an acid mist recovery box and an acid mist absorption pipe. The acid mist absorption pipe connects the tank body to the acid mist recovery box, and an axial flow fan is installed inside the acid mist absorption pipe. An acid liquid flow pipe is also connected to the acid mist recovery box, with one end of the flow pipe away from the acid mist recovery box connected to the tank body. A water pump is installed on the acid liquid flow pipe. This application seals the tank body using a sealing device and draws hydrochloric acid mist from the tank into the acid mist recovery box using the acid mist recovery device. When the acid liquid in the recovery box reaches a certain concentration, the water pump returns the acid liquid to the tank body, achieving the recovery and reuse of hydrochloric acid mist, improving resource utilization efficiency, and also improving the working environment for staff.

[0004] Although the acid mist recovery device for hot-dip galvanizing pickling tanks mentioned above improves resource utilization efficiency, its inconvenience in spraying and purifying uncondensed residual acid mist results in low safety during use. Utility Model Content

[0005] The purpose of this invention is to provide a washing tank acid mist recovery device to solve the problem of inconvenient spraying in existing washing tank acid mist recovery devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a washing tank acid mist recovery device, including a tank body;

[0007] Heating rods are installed on both sides of the bottom of the tank. A lifting structure is fixed on one side of the tank, and a condensation structure is provided on the other side of the tank.

[0008] A spray structure is provided on one side of the condensation structure;

[0009] The spray structure includes a tower body disposed on one side of the condensation structure. An exhaust pipe is fixed to the top of the tower body. A distribution box is fixed to the top of the tower body. Spray nozzles are uniformly fixed inside the distribution box. A packing mesh is fixed inside the tower body below the distribution box. A circulation pump is installed on one side of the bottom of the tower body. A delivery pipe is fixed to the output end of the circulation pump.

[0010] When using this device, the spray structure facilitates purification, thereby improving the safety of the acid mist recovery device for washing tanks; the lifting structure facilitates collection, thereby improving the convenience of use; and the condensation structure facilitates recycling, thereby improving the applicability of the acid mist recovery device for washing tanks.

[0011] Preferably, the lifting structure includes a support, an electric push rod, a collection cover, a guide rod, and a connecting pipe. The support is fixed to one side of the tank. The electric push rod passes through one side of the top of the support. The collection cover is fixed to the bottom end of the electric push rod. A connecting pipe is fixed to one side of the collection cover. Guide rods pass through the interior of the supports on both sides of the electric push rod. The guide rods enhance the stability of the collection cover during movement, allowing it to move to the top of the tank.

[0012] Preferably, the bottom end of the collecting hood abuts against the top end of the tank, the guide rod and the support form a sliding structure, and the bottom end of the guide rod is fixedly connected to the top end of the collecting hood. Under the action of the heating rod, the acid inside the tank is formed into acid mist. At this time, the acid mist enters the interior of the corrugated pipe through the connecting pipe, and the collecting hood can collect the acid mist.

[0013] Preferably, the condensation structure includes a support, a condenser tube, a collection tube, a recovery tube, a drain tube, an air inlet tube, a liquid inlet tube, and a corrugated pipe. The support is disposed on one side of the tank. The condenser tube passes through the top of the support. The collection tube passes through the interior of the condenser tube. The recovery tube is fixed to the bottom end of the collection tube. An air inlet tube is fixed to one side of the collection tube at the bottom end of the condenser tube. A drain tube is fixed to one side of the top of the condenser tube. A liquid inlet tube is fixed to the bottom side of the condenser tube away from the drain tube. A corrugated pipe is fixed to the top end of the collection tube. When acid mist enters the interior of the collection tube through the corrugated pipe, the condenser tube cools the acid mist inside the collection tube, causing the acid mist to condense into liquid.

[0014] Preferably, the end of the air inlet pipe furthest from the collection pipe is connected to one side of the tower body, and the end of the corrugated pipe furthest from the collection pipe is fixedly connected to one end of the connecting pipe. Uncondensed residual acid mist enters the interior of the tower body through the air inlet pipe, and the condensed liquid flows back to the interior of the tank through the recovery pipe for reuse, thereby achieving acid mist recovery.

[0015] Preferably, the input end of the circulating pump extends into the interior of the tower body, and the nozzles are evenly distributed on the inner side of the distribution box. When uncondensed residual acid mist enters the interior of the tower body through the air inlet pipe, the absorbent liquid at the bottom of the tower body will be evenly sprayed down through the nozzles.

[0016] Preferably, the end of the delivery pipe furthest from the circulating pump extends into the interior of the tower and connects to one side of the distribution box. Under the action of the packing mesh, the acid mist and absorbent are in full contact to purify the residual acid mist. The purified gas is discharged through the exhaust pipe, and the absorbent at the bottom of the tower is recycled under the action of the circulating pump.

[0017] The present invention provides an acid mist recovery device for washing tanks, the advantages of which are:

[0018] With a spray structure, when uncondensed residual acid mist enters the tower through the inlet pipe, the absorbent liquid at the bottom of the tower is sprayed evenly through the nozzles. Under the action of the packing mesh, the acid mist and absorbent liquid come into full contact, so as to purify the residual acid mist. The purified gas is discharged through the exhaust pipe. Under the action of the circulation pump, the absorbent liquid at the bottom of the tower is recycled, realizing the purification function of the device and thus improving the safety of the acid mist recovery device for washing tanks during use.

[0019] By incorporating a lifting structure and guided by a guide rod, the stability of the collection hood during movement is enhanced, allowing it to move to the top of the tank. Under the action of the heating rod, the acid inside the tank is condensed into acid mist. At this point, the acid mist enters the interior of the corrugated pipe through the connecting pipe. With the help of the collection hood, the acid mist can be collected, thus realizing the convenient collection function of the device and improving the ease of use of the acid mist recovery device for washing tanks.

[0020] By incorporating a condensation structure, when acid mist enters the collection pipe through the corrugated pipe, the condenser cools the acid mist inside the collection pipe, causing it to condense into liquid. The uncondensed residual acid mist then enters the tower body through the inlet pipe, and the condensed liquid flows back to the tank body for reuse through the recovery pipe. This achieves acid mist recovery, making the device easy to recycle and improving its applicability in use. Attached Figure Description
