Sludge drying field

Abstract

The invention discloses a sludge drying field. According to the technical scheme, the sludge drying field comprises a field room, an energy absorption device, a heating device, a water filtering device and a sludge cleaning device, wherein the energy absorption device is fixedly installed at the top of the field room, the heating device is fixedly installed on the inner wall of the field room, thewater filtering device is fixedly installed at the bottom of the field room, and the sludge cleaning device is arranged at the top of the water filtering device; the sludge cleaning device is fixedlyinstalled on the inner wall of the field room, the field room comprises two sets of symmetrical causeways, rear plates are fixedly installed at the ends of the inner sides of the two sets of causeways, rear partition plates are arranged at the front ends of the rear plates, the two ends of each rear partition plate are fixedly connected with the causeways, and waterproof bottom plates are fixedlyconnected to the bottoms of the two sets of causeways. The sludge drying field has the beneficial effects that light energy intensity is concentrated after the light gathering plate is irradiated bysunlight, so that the temperature in the field room is increased, wet sludge is dehydrated and dried conveniently, the utilization rate of solar energy is increased, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge drying, in particular to a sludge drying field. Background technique [0002] In daily production, a lot of polluted wet mud is usually produced, which is directly discharged to the outside, and there will be certain hazards. Generally, the sludge needs to be dried and disinfected before being buried deeply to prevent the generation of germs from affecting the ecological environment. Sludge drying is the process of removing most of the water content from sludge through percolation or evaporation. It generally refers to the use of self-evaporating facilities such as sludge drying plants. High-viscosity sludge drying equipment generally uses hot air rotary vane dryers. According to the different viscosity of the sludge, a double-axis rotary vane dryer or a three-axis rotary vane dryer can be used to dry high-humidity materials with an initial water content of less than 85% to a final water content of...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following disadvantages: the existing ones are generally carried out in a simple and transparent greenhouse structure, and the main physical principle used is that when sunlight shines on the sludge surface absorber, the air in the drying workshop is heated, and the drying workshop All common types of transparent greenhouses on the market can be used. Although the glass transfers heat quickly, it is easy to produce condensation. Therefore, the greenhouse does not necessarily require safety glass. On the contrary, because the glass is heavy, it is required to install a relatively strong support for the greenhouse components, which not only increases the cost, but also creates a shadow on the drying bed area, and there will be more energy consumption in the production of traditional sludge drying plants
