Description
Technical field
This utility model relates to semi-coke production technical field, is specifically related to a kind of tail of semi coke reutilization system.
Background technology
Coal is completely cutting off the heated under air physics to about the 600 DEG C series of complexes occurred of high temperature, the low temperature distillation of chemical change process, referred to as coal.The production of semi-coke use exactly in low temperature distillation mode.The product of low temperature distillation is in addition to having solid semi-coke, and also liquids and gases, corresponding is exactly tar and tail gas product respectively.The semi-coke technological process of production is broadly divided into three parts such as drying stage, dry distilling stage and semicoke cooling stage.Drying stage: low-disintegration coal drying stage temperature is about room temperature to 300 DEG C, evaporates containing wet moisture in this stage low-disintegration coal, meanwhile, absorption gas abjection in coal hole, finally make feed coal be dried, preheat.The dry distilling stage: produce semi-coke, burnt oil and gas product.Owing to current semi-coke manufacturing enterprise production technology falls behind, cause char yeild low, the substantially all outer row of coal gas, not only resource is caused waste greatly, also environment is caused the biggest pollution simultaneously.Therefore, it is badly in need of at present developing the utilization to tail of semi coke and process.
Summary of the invention
The purpose of this utility model is that the problem such as the tail of semi coke waste for above-mentioned existence and pollution provides a kind of tail of semi coke reutilization system, its advantage obtained is that it has raising tail of semi coke utilization rate of active components, reduce energy consumption, reduce the advantage such as atmospheric pollution and dust harzard.
The technical solution of the utility model is as follows:
A kind of tail of semi coke reutilization system, including irradiation modules, dry distilling module and semicoke refrigerating module, three modules are sequentially connected, raw material passes sequentially through three modules and prepares finished product semi-coke, tail gas recycle recycling module it is additionally provided with, including tail gas collecting device, gas furnace, heat exchange of heat pipe, preheating apparatus and waste gas isolation of purified processing means in described dry distilling module.
Described tail gas collecting device one end is connected with irradiation modules, and the other end connects gas furnace by appendix；Described gas furnace is connected with irradiation modules by thermal energy transfer duct road, gas furnace air vent is connected with heat exchange of heat pipe by appendix, heat exchange of heat pipe connects preheating apparatus by thermal energy transfer duct road, and heat exchange of heat pipe air vent is provided with isolation of purified processing means.Heat energy is inputted irradiation modules by gas furnace, by appendix, waste gas is inputted heat exchange of heat pipe, and waste gas enters heat exchange of heat pipe by appendix, enters waste gas isolation of purified processing means after heat exchange, the heat energy input preheating apparatus of heat exchange of heat pipe, further increases the service efficiency of the energy.
As preferably, described tail gas collecting device includes that coal tar device, desulfurizer, air-introduced machine and cleaner unit are received in electric fishing, first by coal tar recovering, then carries out desulfurization process, improves the value of tail gas, prevents dust pollution.
As preferably, the appendix between described gas furnace and heat exchange of heat pipe is provided with Pressure gauge.
In order to improve the efficiency of combustion of gas furnace, described gas furnace is provided with oxygen supply device.
In order to prevent the loss of heat energy, improve energy utilization rate, outside described appendix, be provided with one layer of heat preservation layer.
The beneficial effects of the utility model are:
This utility model is novel, add up to ingenious rationally.Derive by semi-coke being produced the tail gas of dry distilling stage generation, carry out coal tar oil recovery, again the residual gas after desulfurization and dedusting is burnt and discharge heat energy for drying stage, simultaneously the most further by the heat energy in the waste gas after burning again with, there is provided for raw material and preheat, substantially increase the service efficiency of the energy, reduce the energy consumption of drying stage, and be effectively reduced atmospheric pollution and dust pollution.
