Vehicle-mounted detachable cleaning apparatus and quasi-on-line cleaning method for heating system

Abstract

A quasi on-line cleaning method of vehicle mounted detachable type cleaning system and heating system is composed of a detachable device box and a control box, a centrifugal pump, an air compressor, a diesel generator and a chemical pump are mounted in the device box, a water extracting system, a circulation commutating system, a water and air mixing loop wire, a outlet cleaning pollution discharge line and an electric control system are mounted in the control box, the pipelines between the device box and the control box are connected by flexible flanges; the air and water mixing is provided with pulse power for the cleaning water, the circulation commutating system can change the cleaning direction, the pressured drill is connected with a water supplying and returning main pipe of a heating system to form an independent circulation system to perform commutation repeat cleaning, thereby the heating system can implement the cleaning operation without stopping heating, the pipe is not cut, the cleaning speed is fast, the cleaning effect is good without blocking and polluting environment, the cleaning is pure physical operation; the use range of the quasi on-line cleaning device can be extended by the chemical cleaning agent supply system; the effective service radius of the use range is 300 km. In the non-cleaning season, the device can be dismounted only one day, the load-carrying transportation performance of the vehicle can be recovered.

Description

technical field [0001] The invention relates to a cleaning device for a pipeline and a liquid storage tank system, in particular to a vehicle-mounted detachable cleaning system and a quasi-online cleaning method for a heating system using physical and chemical methods. Background technique [0002] In my country, 50% of the regions need heating indoors in winter, and more than 600 million people rely on hot water heating systems for heating to survive the cold winter. At present, more than 99.8% of my country's indoor heating in winter is hot water heating. [0003] The general design life of the hot water heating system is 25-30 years, but the heating efficiency of the heating system decreases year by year after 6-8 years of operation. Usually, the radiator fails to meet the heating requirements after 10-15 years of operation and the indoor low temperature occurs. The essential reason for this problem is the scaling of the heating system. The main hazards of the scaling of...

AI Technical Summary

Problems solved by technology

Although the corresponding corrosion inhibitors and passivators are added to the chemical cleaning agent, due to the non-uniformity of surface scaling in the heating system, the corrosion of the pipe wall by the chemical cleaning agent is inevitable. , Alkali naturally precipitates and corrodes the lower part of the pipeline, causing strong corrosion in the lower part of the heating pipeline, thinning the pipe wall, and reducing the service life of the pipeline

At the same time, the discharge of residual liquid has also caused environmental pollution on the ground.

The second is to dismantle the old pipelines and radiators of the low-temperature building in summer and replace them with new ones; 2 The cost of dismantling and replacing the heating system of residential buildings in China is about 250,000 yuan (excluding the cost of removing and restoring indoor pipelines and the decoration of radiators). At the same time, there are still problems such as long construction period and affecting residents' lives.

[0008] 1. During the half year of the non-heating season, the vehicles used for vehicle-mounted heating and cleaning equipment are idle, causing a lot of waste;

[0009] 2. The circulation reversing system in the vehicle heating and cleaning equipment is placed outside the vehicle and needs to be installed and connected separately;

[0010] 3. In addition to the heating system, the vehicle-mounted heating and cleaning equipment cannot be used for the cleaning of other pipelines and liquid storage tanks. For example, there are many oil storage tanks in Daqing, which also need to be cleaned regularly
