Technical characteristics and advantages of steam sludge dryer

As a result of coal combustion will produce a large number of carbon and sulfur oxides, environmental pollution is very large, once the surrounding residents complain, the loss of enterprises will be very large. Therefore, according to the environmental protection requirements, the traditional coal-fired sludge dryer is used less and less. The sludge dryer manufacturers have developed a new type of steam sludge dryer by updating the heat source equipment and strengthening the tail gas dust removal, that is, the large-scale drying equipment that uses steam as the heat source to dry high humidity and high viscosity materials. At present, the steam sludge dryer has become a solution to the environmental protection problem One of the main methods.

Compared with traditional coal-fired and fuel oil, steam is a clean fuel. Steam as a heat source has the following advantages:

1. Good cleanliness. When coal is burned, a lot of sulfur dioxide and nitrogen oxides will be produced, so it is difficult to treat the waste gas. Steam as a heat source is not only clean, but also much simpler.

2. High cost performance. Compared with natural gas, using steam as heat source is cheaper and more cost-effective.

Therefore, in terms of ecological environment protection, steam has more advantages than coal and other fossil fuels. Using steam as heat source instead of traditional energy, the sludge dryer can not only reduce the impact of waste gas and dust on the environment, but also save energy. Now, more and more enterprises begin to use steam as the heat source of sludge dryer.

Technical features of steam sludge dryer:

1. Compared with the traditional equipment, the steam sludge dryer reduces the investment. The installation of the equipment is simple and convenient. It can be installed indoors and outdoors with less investment in civil engineering.

2. High degree of automation, only 1 ~ 2 people can complete the drying operation, simple and convenient operation, stable performance and continuous operation;

3. It adopts three-stage multi loop drying process with negative pressure operation, good sealing performance and good insulation effect, which can effectively reduce energy consumption

4. The dust containing waste gas in the drying process is purified and filtered by the purification and dust removal equipment, which can meet the national emission standards and reduce the impact on the environment.
