高压清洗机在我国推广应用的经济效益Economic benefits of the popularization and application of high-pressure cleaner in China

目前在国有大中型企业及各大城市已占有5%左右的比例，并且还在持续高速发展。目前无论是国营企业，还是民营清洗公司都看好这一方兴未艾的新兴产业，发展这一投资回报短平快的高新技术产业。下面主要介绍一下高压清洗机在我国推广应用的经济效益分析。
At present, it has accounted for about 5% of state-owned large and medium-sized enterprises and major cities, and is still developing at a high speed. At present, both state-owned enterprises and private cleaning companies are optimistic about this emerging industry and developing this high-tech industry with short return on investment. The following mainly introduces the economic benefit analysis of the promotion and application of high-pressure cleaner in China.
根据高压清洗机使用方多年清洗施工的经验，拥有高压清洗机的清洗公司，如果每年按半年工作，其经济效益可概括如下：
According to the years of cleaning construction experience of the user of high-pressure cleaning machines, the economic benefits of cleaning companies with high-pressure cleaning machines can be summarized as follows if they work half a year:
1、各类管道清洗
直径在150～500mm的一般上下水及排污管道，清洗公司每个班次通常可清洗150m，如果每米计费按50-80元来算，每个月工作20个班次，则每台设备每月经济收入就高达15-24万元。若每年工作6个月，则每台设备年利润就可达到90-140万元。
1. Various pipeline cleaning
For general water supply, drainage and sewage pipes with a diameter of 150~500 mm, the cleaning company can usually clean 150 m per shift. If the cost per meter is calculated as 50-80 yuan, and 20 shifts per month are worked, the monthly economic income of each equipment will be as high as 1.5-24 million yuan. If you work for 6 months every year, the annual profit of each equipment can reach 90-14 million yuan.

2、热交换器清洗

热交换器是一种热能转换和余热利用的设备，在化工厂、发电厂及石化企业等工业领域应用十分广泛。有的大型企业一个生产基地就拥有几十台甚至上百台热交换器。由于冷却水在热交换过程中，冷冻水吸收了冷却水的热量，使其温度上升，此时原来溶于水中的Ca(HCO3)2和Mg(HCO3)2在温度的作用下析出CO2生成微溶于水的CaCO3和MgCO3。由于CaCO3和MgCO3的溶解度随温度的上升而下降，从水中结晶析出，当这些结晶物不断地沉积于热交换器表面，便形成了很硬的水垢，这不但影响了热交换效率，还增加了能耗，严重时还会因冷却水的流量不足和压力降低导致停机，所以热交换器使用一段时间后必须进行清洗。中型、一般结垢的热交换器，清洗公司平均一个班次就能清洗一台，如果按每台清洗价格50008000元来计算，每个月工作20个班次，则每台设备每月收入可达10-16万元。若每年工作6个月，则每台设备的年利润就可达到60-96万元。

2. Heat exchanger cleaning
Heat exchanger is a kind of equipment for heat energy conversion and waste heat utilization, which is widely used in chemical plants, power plants, petrochemical enterprises and other industrial fields. Some large enterprises have dozens or even hundreds of heat exchangers in one production base. Because the cooling water absorbs the heat of the cooling water during the heat exchange process, the temperature of the cooling water rises. At this time, Ca (HCO3) 2 and Mg (HCO3) 2 that were originally dissolved in the water precipitate CO2 under the action of temperature to generate CaCO3 and MgCO3 that are slightly soluble in water. Because the solubility of CaCO3 and MgCO3 decreases with the rise of temperature, and crystallizes out of water. When these crystals are continuously deposited on the surface of the heat exchanger, they form very hard scale, which not only affects the heat exchange efficiency, but also increases energy consumption. In serious cases, the cooling water flow is insufficient and the pressure is reduced, resulting in shutdown, so the heat exchanger must be cleaned after a period of use. For medium and general scale heat exchangers, the cleaning company can clean one heat exchanger per shift on average. If the cleaning price of each heat exchanger is 50008000 yuan and 20 shifts per month are worked, the monthly income of each equipment can reach 100000 to 16000 yuan. If you work for 6 months every year, the annual profit of each equipment can reach RMB 60-960000.

3、锅炉、暖气管道、大型罐体及容器等清洗
锅炉、暖气管道、大型罐体及容器运行一段时间以后势必会发生结垢问题，而高压水射流具有冲刷、楔劈、剪切、磨削等复合破碎作用，可立即将结垢物打碎脱落并冲走，从而实现垢层和管壁的分离。所以高压清洗机正是最理想的清洗设备，当高压水射流不能直射时，辅以化学方法，其经济效益与上述大致相等。
3. Cleaning of boilers, heating pipes, large tanks and containers
The boiler, heating pipe, large tank and container will inevitably have scaling problems after a period of operation, and the high-pressure water jet has the combined crushing effects of scouring, wedging, shearing, grinding, etc., which can immediately break the scaling off and wash away, thus realizing the separation of the scale layer and pipe wall. Therefore, high-pressure cleaning machine is the most ideal cleaning equipment. When high-pressure water jet can not be directly shot, chemical methods are used, and its economic benefits are roughly equal to the above.

综上所述，我们可以看出高压清洗机的应用能够带来巨大的经济效益，而购买一台高压清洗机，所需成本只需要3、4个月即可收回。因此，高压清洗机这种新型清洗设备的发展前景是非常广阔的。

To sum up, we can see that the application of high-pressure washer can bring huge economic benefits, while the cost of purchasing a high-pressure washer can be recovered in only 3 or 4 months. Therefore, the development prospect of high-pressure cleaning machine, a new type of cleaning equipment, is very broad.
