Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to double-effect concentrators, in particular to a double-effect concentrator with a condensed water recovery and recycling mechanism. Background Art

[0002] In the chemical industry, some liquid raw materials such as liquid medicine and concentrate need to be concentrated to increase the content. When concentrating liquid raw materials, the commonly used method is vacuum distillation, which is usually carried out through a single-effect evaporator. However, the efficiency of the single-effect evaporator is not high, which has given rise to the birth of the double-effect concentrator. The double-effect concentrator is a combination of two single-effect evaporators. The double-effect concentrator uses two effects at the same time to fully utilize the secondary steam, which saves both boiler investment and energy consumption.

[0003] For example, a double-effect concentrator condensate water recovery and recycling device with publication number CN216169999U includes a confluence mechanism connected to the outlets of the first-effect condenser and the second-effect condenser, and a cooling water pool is arranged below the confluence mechanism. The utility model connects the condensate water outlets of the two condensers in the double-effect concentrator through the confluence mechanism, converges the condensate water generated by the double-effect concentrator to the cooling water pool, draws the water in the cooling water pool to the filter through the first circulation mechanism, and then discharges it back to the cooling water pool after filtering, and draws the cooling water in the cooling water pool to the double-effect concentrator through the second circulation mechanism, so that the condensate water generated by the double-effect concentrator is recycled and utilized, avoiding the waste of water resources.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can reduce the waste of water resources to a certain extent, in actual use, the above device lacks a relatively weak cooling effect on the circulating water, which affects the circulation efficiency of the condensed water to a certain extent when used.

[0005] Therefore, in order to solve the above problems, a double-effect concentrator with a condensed water recovery and recycling mechanism is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the existing technology has the disadvantage of relatively weak cooling effect on circulating water. For this reason, we propose a double-effect concentrator with a condensed water recovery and recycling mechanism.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a double-effect concentrator with a condensate recovery and recycling mechanism, comprising a cooling tank; a water storage tank is fixedly installed at the bottom of the cooling tank, a connecting plate is fixedly installed at the bottom of the inner cavity of the cooling tank, an upper storage box is fixedly installed at the bottom of the connecting plate, a condensing pipe is fixedly installed at the bottom of the upper storage box, a lower storage box is fixedly connected to the bottom of the condensing pipe, a temporary box is fixedly connected to the bottom of the lower storage box, a pump is fixedly installed at the bottom of the temporary box and located at the bottom of the water storage tank, and a water outlet flange is fixedly installed at the bottom of the pump.

[0008] Preferably, a water inlet flange is fixedly installed at the middle portion of one side of the cooling tank, and a drain pipe is fixedly installed at the bottom of the water inlet flange.

[0009] Preferably, an air intake flange is fixedly mounted on one side of the top of the cooling tank, and a second air transfer pipe is fixedly connected to the other side of the air intake flange.

[0010] Preferably, the other end of the second air transfer tube is fixedly connected to a second concentration tank, a control panel is fixedly mounted on the front of the second concentration tank, and operation buttons are arranged on the surface of the control panel.

[0011] Preferably, a second heating tank is fixedly installed on the other side of the second concentrating tank, a first air transfer tube is fixedly connected to the top of the second heating tank, and the other end of the first air transfer tube is fixedly connected to the first concentrating tank.

[0012] Preferably, a first heating tank is fixedly installed on the other side of the first concentrating tank, and the bottoms of the first concentrating tank and the second concentrating tank are both connected to a return pipe, and the return pipe is fixedly connected to the water outlet flange.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model facilitates the circulation of refrigerated water by setting a cooling tank. The cooling tank and the water storage tank at the bottom form a sealed whole. The cooling water can circulate in the whole, thereby cooling the condenser. The connection plate is set to enhance the installation strength of the upper storage tank. The upper storage tank and the lower storage tank are respectively installed at the upper and lower ends of the condenser. The interior is hollow and can store moisture after steam condensation. The water vapor generated by the concentration of the material in the concentrator enters the cooling tank along the pipeline. The condenser in the cooling tank is always immersed in cooling water with a lower temperature, so the temperature of its inner wall is relatively low. When the steam hits the low-temperature inner wall, it will be converted into liquid and flow into the temporary box at the bottom along the pipeline. The temporary box is connected to a pump to circulate the liquefied steam into the concentrator again for subsequent use in generating high-temperature steam.

[0015] 2. The utility model facilitates the introduction of cooling water for cooling the condenser into the space formed by the cooling tank and the water storage tank through the provision of the water inlet flange and the drain pipe, facilitates the guidance of high-temperature steam into the condenser through the provision of the air inlet flange, facilitates the user to electrically control the device through the provision of the control panel and the operation buttons, facilitates the concentration of materials through the provision of the first concentrating tank and the second concentrating tank through the provision of the return pipe, and facilitates the guidance of the condensed steam water into the first concentrating tank and the second concentrating tank through the provision of the return pipe.
