Background

In summer and autumn and winter every year, a large amount of straws of wheat, corn and the like are incinerated in the field, a large amount of dense smoke is generated, and the straw incineration method not only becomes a bottleneck problem of rural environment protection, but also even becomes a chief culprit of compromising urban environment. According to relevant statistics, as a big agricultural country, China can generate more than 7 hundred million tons of straws every year, and the straws become wastes which are not used much but need to be disposed. In this case, a phenomenon of incineration occurs in large quantities, which is completely handled by farmers.

The crop straw belongs to a valuable biomass energy resource in an agricultural ecological system. The comprehensive utilization of the crop straw resources has great significance for promoting the income increase of farmers, protecting the environment, saving the resources and developing the sustainable agriculture economy. In order to solve the problem, China has a lot of active exploration and creatively adopts a plurality of beneficial experiences and methods. If the straw is used for making paper or the straw board without formaldehyde series is produced by using the straw, the straw board can be widely used as base materials of high-grade furniture, high-grade packaging, high-grade building materials, high-grade sound boxes and the like, the income of farmers can be increased, the income of foreign exchange can be increased, and the straw resource is converted into economic advantages; encourages farmers to enlarge the breeding scale and leads the straw to become coarse fodder of cattle and sheep; in some places, straw gasification principles and technologies are utilized to implement straw biogas engineering in rural areas, which is very significant. However, the specific process for straw utilization is still imperfect, the straw processing equipment and related processing facilities are limited, the straw utilization technology is relatively low, and the efficiency and benefit of straw comprehensive utilization need to be improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a processing apparatus about straw solid waste in order to solve the above-mentioned problem, furthest turns into usable resource with the straw when solving straw solid waste problem.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model provides a processing apparatus about straw solid waste, include the casing that comprises inside and outside two-layer steel sheet, support frame and air vent and the wire through-hole that runs through the inside cavity of casing including setting between the inside and outside two-layer steel sheet, the air vent is equipped with the valve, the casing is equipped with the sealing door, the sealing door is with the inside cavity of casing and external isolated the opening, be equipped with the heat preservation at the inside cavity of casing, the inner steel sheet one side is kept away from on the heat preservation case layer is equipped with the couple, hang the resistance wire on the couple, outside wire passes the wire through-hole.

A confined space has been built through above-mentioned scheme, can carry out heat treatment to the straw waste material in this confined space, and the confined space does not contact with the outside air, and the straw can not burn during the heating, and straw pyrolysis produces straw gas, and the clout can regard as active carbon to use for sewage treatment, air purification, impurity adsorption etc. and the active carbon after the use still can regard as fuel to use after the drying, so very big improvement the utilization ratio of straw.

Preferably, the number of the vent holes is two, one vent hole is connected with the vacuum pumping equipment, the other vent hole is connected with the air storage bag, and the vent hole connected with the air storage bag is provided with a barometer for detecting the air pressure of the cavity in the shell. On one hand, the vacuum pumping equipment is used for vacuumizing the cavity of the shell, so that oxygen in the cavity of the shell can be reduced, and the generation of carbon dioxide can be reduced; on the other hand, the straw gas is more favorable for generating the straw gas in a vacuum environment.

Preferably, the gap between the wire through hole and the wire is filled with a heat-resistant filler.

Preferably, a reflective screen having a smoothness of 10- & lt 12 & gt is suspended on the support frame. Have a large amount of heat energy to pass to the casing outside through the form of heat radiation in the heating process, increase behind the reflecting screen can effectual reduction penetrate the influence of radiation to the user of service, reduce the loss of electric energy simultaneously.

Preferably, the air storage bag is made of a fire-resistant material with elasticity.

Preferably, the refractory layer is a refractory brick.

The utility model has the advantages that:

1. the utility model discloses simple structure, stability is high, reasonable in design, the realization of being convenient for.

2. The utility model discloses application scope is wide, can be applicable to the processing of multiple agricultural straw waste material.

3. The utility model discloses it is abundant to the conversion product of straw discarded object, and the conversion rate is high, and the conversion process is pollution-free.
