Low-cost environmental protection cleaning system with ice crystals as working medium

Abstract

The invention discloses a low-cost environmental protection cleaning system with ice crystals as a working medium. The low-cost environmental protection cleaning system has the strong cleaning ability, and is provided with a high-pressure water conveying pipe (1), a high-pressure pump (7) and a first valve (2) are sequentially connected to the inlet end of the high-pressure water conveying pipe (1), an outlet of the high-pressure water conveying pipe (1) is connected to a capillary tube nozzle (3), and a semiconductor refrigerator (4) is arranged at the position, outside the high-pressure water conveying pipe (1), at the rear end of the first valve (2); and a temperature sensor (5) is arranged on the high-pressure water conveying pipe (1) or the capillary tube nozzle (3) at the rear end ofthe semiconductor refrigerator (4), and the temperature sensor (5) and a PID controller for controlling the semiconductor refrigerator (4) to the zero degree are connected.

Description

technical field [0001] The invention relates to the field of cleaning, in particular to a low-cost and environment-friendly cleaning system with strong cleaning ability and using ice crystals as the working medium. Background technique [0002] It can be used in a wide range of cleaning systems. Such as cleaning the oil, grease and dirt on the surface of large objects such as aircraft, ships, gas storage, oil storage tanks, automobiles, trains, trucks, etc.; cleaning the paint, rust and stains on the surface of belt conveyor systems, molds and mechanical equipment , dirt, etc.; cleaning graffiti, posters, etc. on the inner and outer surfaces of buildings; cleaning machinery, equipment and workplaces in food production and processing industries. Existing cleaning systems include dry ice cleaning machines, sandblasting cleaning machines, high-pressure water jet cleaning machines and chemical cleaning. [0003] The dry ice blasting machine is composed of three parts: dry ice ...

AI Technical Summary

Problems solved by technology

The disadvantage is that the cost of dry ice processing is high, and it is easily affected by gasification, so the scope of application of this cleaning machine is small, and it is extremely unsuitable for cleaning large areas such as outdoors.

The structure of the sandblasting cleaning machine is similar to that of the dry ice cleaning machine. It uses particles such as baking soda to be sprayed onto the surface of the object to be cleaned under the action of high-pressure gas. The disadvantage is that the environment is polluted and the workload of cleaning the work site is large. industry

At the same time, because the nozzle will generate strong static electricity, it cannot be used in places with explosion-proof requirements.

The high-pressure water jet cleaning machine uses high-pressure water to directly spray the surface of the object to be cleaned. Although it is low in cost and environmentally friendly, due to its poor cleaning ability, it is only suitable for the surface of dusty objects with low adhesion and low cleaning requirements.

Chemical cleaning is only suitable for special industries due to serious environmental pollution
